Abstract

A field experiment consisted of seven pea based cropping sequences viz. Pea-mustard 'NDRE 4', Pea-mustard 'JD 6', Pea-toria 'Bhawani', Pea-local sarson 'Yungar', Pea-French bean 'Contender', Pea-buckwheat 'Local' and Pea-buckwheat 'USDA' was conducted at Kukumseri (Lahaul and Spiti) during 2010 and 2011 to find out the most remunerative second crop after main pea crop for dry temperate conditions of western Himalayas. The local sarson 'Yunger' took the least days (58 days) for maturity closely followed by French bean. Buckwheat USDA took highest number of days (92) to mature. Among new introduced mustard varieties 'NDRE 4' took 81 days. The highest pea equivalent yield (6377 kg/ha) with net return of INR 86714/ha and B: C ratio of 1.82 was obtained from pea-Frenchbean 'Contender' sequence followed by pea-mustard 'NDRE 4' (5561 kg/ha) with net return of INR 81478/ha and B: C ratio of 1.86. The increase in yield and net return with the best sequence (pea-Frenchbean 'Contender) over the most prevalent pea- local sarson 'Yunger' sequence was 24.9 and 23.8%, respectively.

Abstract

Aerobic rice is a method of rice cultivation in which the crop is raised under un-puddle non-saturated aerobic condition with high external inputs with the objective of achieving higher productivity and water use efficiency. A field experiment was conducted during kharif 2012 at Malan to standardize seeding time for six promising rice varieties (four high yielding varieties and two locally recommended hybrids) under aerobic conditions. Each variety was sown at three different dates (10, 20 and 30 June). On an average, significantly higher grain yield was recorded when the sowing was done on 20 June though it was at par with 10 June sowing. Among the varieties, on an average hybrid PAC 807 gave significantly highest yield followed by Arize 6129. However, while comparing different combinations of seeding and variety altogether, Arize 6129 gave significantly highest yield when sown on 10 June. Among the HYVs tested, highest yield was recorded from HPR 1068 while HPR 2143 gave lowest yield. The economic indices calculated also showed similar trend with hybrids showing higher values for gross and net return but had lower B:C ratio owing to the higher cost of seed.

Abstract

A field experiment to know the efficacy of some new fungicides against neck blast was conducted at Rice and Wheat Research Centre, Malan (HP) during Kharif 2014. New combination product of tricyclazole 18% + mancozeb 62% (MERGER) was found quite effective resulting in 72.6 per cent reduction in disease incidence over control, while application of tricycalzole 75 WP alone reduced neck blast incidence by 69.2 per cent. Another combi-fungicide, ICF-110 (tricyclazole 45% + hexaconazole 10% WG) also resulted in significant reduction (67.8%) in neck blast incidence over control. Also, the new molecules i.e. MERGER and ICF-110 significantly enhanced the grain yield as compared to rest of the fungicides with 192.5 and 176.1 per cent increase in grain yield over control.

Abstract

Farmers of Lahaul were using upto four times higher seed rates of peas which was not only their concern but of the scientists and the policy makers. Therefore, seed rates (100,150, 200, 250, 300 and 350 1^/ha) with recommended (20:60:30 :: kg N:P₂0₅,:K₂0/ha) and 150% NPK were evaluated at Highland Research and Extension Centre, Kukumseri during 2010 and 2011 to find out optimum seeding rate of peas under dry temperate region of Northwestern Himalayas. It was observed that emergence count and final plant stand of peas increased with increase in the seed rate upto 300 1^/ha during 2010 and upto 350 kg/ha during 2011. Pods/plant was also significantly affected during 2010. But there was consistent decrease in pods/plant beyond the seed rate of 150 kg/ha. Seeds/pod and seed weight/pod were not significantly affected during both the years. Peas green pod yield was significantly increased upto a seed rate of 250 kg/ha during 2010 and at 200 kg/ha during 2011. Yield attributes and yield of peas were not significantly influenced due to fertility levels.

Abstract

A field experiment was conducted at CSK HP Krishi Vishvavidyalaya, Rice and Wheat Research Centre, Malan during kharif 2016 to find out the bio-efficacy of new herbicide rinskor 2.5% EC in wet seeded rice (sowing of sprouted rice seeds in puddled fields). Four herbicide treatments comprising single herbicide rinskor at two doses (31.25 and 37.5 g a.i./ha 4-7 leaf stage of weeds), bispyribac sodium 30 g a.i./ha 3-4 leaf stage of weeds, and sequential application of pyrazosulfuron ethyl (25 g 3-5 days after sowing; DAS) followed by (fb) metsulfuron methyl + chlorimuron ethyl (4 g 25-30 DAS) were evaluated along with weed free (three hand weedings; 20 40 & 60 DAS), two hand weedings and weedy check. The crop was heavily infested with weeds (288.7/m²) viz., Monochoria vaginalis, Commelina benghalensis, Digitaria sanguinalis, Paspalum paspalodes, Echinochloa colona, E. crusgalli, Eleusine indica, Phyllanthus niruri and Setaria glauca, thus recording significantly more dry matter of both grass and broadleaf weeds compared to different weed control treatments. The weed index (increase in yield over weedy check) of different weed control treatments recorded values of 23.1 to 43.6 per cent; highest being with rinskor 37.5 g/ha. Rinskor at both the doses, bispyribac and sequential application of pyrazosulfuron ethy Jb metsulfuron ethyl + chlorimuron behaved alike in reducing weed density and were at par with two hand weedings. Rinskor and bispyribac were statistically equally effective in reducing dry matter of broad leaf weeds and were at par with weed free treatment. The significant effect of weed control treatments was reflected in growth and yield attributes of the crop. Rinskor 37.5 g/ha recorded tillering (336/m²) and panicles (320/m²) and grain (4.35 Mg/ha) at par with its lower dose (31.25 g/ha) and weed free treatment (weeding at 20,40 & 60 DAS). Thus, the new herbicide, rinskor 37.5 g/ha may be applied at 4-7 leaf stage of weeds (25 DAS) for efficient control of mixed weed flora in wet seeded rice.

Abstract

A field experiment was conducted during kharif 2019 at the Research Farm of Department of Agronomy, College of Agriculture CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the bio efficacy of new herbicide for managing weeds in undulating pasture land pockets. The experiment was laid out in Randomised Block Design with three replications, and consisted of seven weed control treatments including GOD H007 at 860, 882 and 903 g/ha, pyrithiobac sodium 62.5 g/ha, glyphosate 820 g/ha, hand weeding and a weedy check. Application of this new herbicide combination product GOD H007 903 g/ha though remaining statistically alike with glyphosate 820 g/ha, resulted in significantly lowest total weed density and total weed dry matter at all the stages of observation except that at 30 days after spray (DAS) at which hand weeding proved to be a superior treatment. These three treatments interventions also recorded higher weed control efficiency. However, significantly highest fresh and dry herbage yield at 60 DAS was recorded with the application of pyrithiobac sodium 62.5 g/ha. Application of this new herbicide GOD H007 903 g/ha showed promise to be effective for managing weeds in pasture land.

Abstract

A field experiment was conducted at the Experimental Farm of Department of Agronomy of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur (H.P.) during kharif 2019 to study the growth and performance of rice hybrids under varying fertility levels. The treatments consisted of four rice varieties (three hybrids viz., Arize 6129, Arize Swift, AZ 6508 and inbred HPR 2143) which were tested under five fertility levels viz., 50% recommended dose of fertilizer (RDF), 100% RDF (90:40:40), 150% RDF, 150% RDF + ZnSO₄ @ 25 kg ha-1 and natural farming treatment. The trial was laid out in split plot design with fertility levels in main plot and rice varieties in sub plot and was replicated thrice. Plant height and dry matter accumulation were significantly influenced by fertility levels with highest values recorded with the application of highest dose of fertilizers along with zinc while significantly lower values recorded in natural farming treatment. Significantly higher values of crop growth rate (CGR) and relative growth rate (RGR) at both the stages (between 30-60 days and 60–90 days after transplanting, DAT) were recorded with the application of 150% RDF + ZnSO 4though this treatment was at par with the application of 150% RDF alone. Significantly lowest values of both these parameters at both the stages were recorded with the natural farming treatment. Varieties also differed significantly with HPR 2143 producing significantly taller plants while Arize Swift producing shorter plants. Hybrids accumulated more dry matter as compared to inbred HPR 2143 with AZ 6508 recording significantly higher value of this parameter. Among the varieties tested AZ 6508 recorded significantly higher values of CGR, RGR and NAR at both the stages of observation indicating higher potential of this hybrid.

Abstract

A field experiment was conducted at the farmers’ field in Panchrukhi block of Kangra District (H.P.) during kharif 2019 to evaluate the bio-efficacy and phytotoxicity of glyphosate 41% SL in tea (Camellia sinensis). The experiment was laid out in a Randomized Block Design with ten treatments and was replicated thrice. The treatments comprised of six doses of a new formulation of glyphosate 41 % SL (All Clear, Anu Products Ltd.) 1.0, 2.0, 3.0, 4.0, 5.0 and 8.0 litre / ha, glyphosate 41 % SL (Roundup, Monsanto), glyphosate 71 % SG 3.0 kg / ha and weedy and weed free checks. Major weeds that were found to infest the experimental tea orchard included Erigeron canadensis, Ageratum conyzoides, Cynodon dactylon, Imperata cylindrica, Paspalum conjugatum and Polygonum alatum. The results revealed that in tea crop weeds can be effectively controlled with the application of glyphosate 41% SL (All Clear) 3.0 litre/ha and 4.0 litre/ha. No phytotoxicity symptoms on tea were observed at any of dose of herbicide.

Abstract

An experiment with nine orchard floor management practices viz., legume intercropping (soybean-peas), turmeric intercropping, fodder intercropping (pearl millet-oats), sod culture (setaria grass), glyphosate, paraquat, weed mulch, manual weeding and weedy check was carried out at Palampur during kharif 2018 to rabi 2019-20 to study their effect on fruit quality and yield of peach. Highest weed population was recorded in weedy check in all the months and lowest weed count was observed in legume intercropping during both the years. Legume intercropping resulted in highest peach yield and quality over rest of the treatments and lowest fruit yield per tree was recorded under weedy check during both the years of study. Uninterrupted growth of weeds reduced the fruit yield by 41.13 per cent during 2019 and by 50.84 per cent during 2020. No phytotoxicity of any herbicide tested (pendimethalin, quizalofop and chlorimuron ethyl to intercrops and directed application of glyphosate and paraquat) was recorded on peach indicating that all the herbicides used were safe for managing weeds in peach orchard.

Abstract

The field experiment was conducted at the Experimental Farm of Department of Agronomy, CSK HPKV, Palampur during kharif 2019 and 2020 to find out the effect of ethalfluralin 36 % EC on weeds, yield attributes and their correlation with yield of soybean. Nine weed control treatments viz. ethalfluralin 540 g/ha, 630 g/ha, 720 g/ha, 810 g/ha, 1440 g/ha, imazethapyr 100 g/ha, pendimethalin 1000 g/ha, weed free treatment and weedy check were tested in Randomized Block Design with four replications. Soybean variety ‘Harit soya’ was sown manually in furrows 45 cm apart using a seed rate of 100 kg/ha. Results revealed that ethalfluralin 810 g/ha proved statistically superior to all other treatments in reducing the weed population and weed dry weight at harvest during both the years. Plant height, branches per plant, 1000 seed weight and seed yield of soybean was significantly higher with the application of ethalfluralin 720 g/ha behaving statistically alike with 810 g/ha followed by imazethapyar 100 g/ha and pendimethalin 1000 g/ha during both the years of study. Correlation studies carried out between different parameters revealed that plant height, branches per plant, 1000 seed weight and straw yield were positively and significantly correlated with the seed yield of soybean.

Abstract

This two-year research was aimed to identify the relationships between irrigation and nutrient management practices on crop growth and yield. Treatments consisted of three irrigation levels viz. recommended critical stages regimes (I₁), irrigation at 0.6 CPE (I₂) and irrigation at 1.0 CPE (₂) in main plots and four nutrient management practices viz. inorganic nutrient management (F₁), organic nutrient management (F₂), natural farming management (F₃), integrated nutrient management (F₄) in subplots, laid out in split-plot design with three replications. It was revealed that irrigation at 1.0 CPE (I₃) produced significantly taller plants and higher dry matter accumulation but did not influence the days taken for 50 % flowering and physiological maturity. Nutrient management practices also had a significant influence on these parameters in which integrated nutrient management (F₄) was found to be superior for dry matter accumulation, plant height, days taken for 50 % flowering, physiological maturity and yield.

Abstract

An experiment was conducted to study the effect of tillage practices and different nutrient sources on growth, growth indices and yield of mustard. The experiment was directed in split plot design comprising of three main plots [(Zero tillage, Reduced tillage and conventional tillage) and four sub plots (75% RDN, 100% RDN, 75% RDF and 100% RDF) treatments]. Results revealed that plant height (137.92 cm), dry matter accumulation 2 2 (393.03 g/m ), absolute growth rate (0.20 g/day), crop growth rate (0.83 g/m /day), dry matter efficiency (0.149 %), 2 unit area efficiency (0.00062 kg/ m /day), seed yield (1045.0 kg/ha) and straw yield (3242.3 kg/ha) of mustard were highest under reduced tillage. Among different nutrient sources, 100 per cent recommended 2 dose of fertilizer recorded highest plant height (139.72 cm), dry matter accumulation (407.81 g/m ), dry matter 2 efficiency (0.151 %), unit area efficiency (0.00065 kg/ m /day), seed yield (1098.4 kg/ha) and straw yield (3112.6 2 kg/ha) whereas absolute growth rate (0.17 g/day) and crop growth rate (0.77 g/m /day) were highest with 75 per cent recommended dose of fertilizer. Correlation studies showed that plant height, dry matter accumulation, absolute growth rate, dry matter efficiency and unit area efficiency had positive significant association with mustard yield, indicating the importance of these traits in selection for yield. It was concluded that among tillage practices, reduced tillage proved best for growth and productivity of mustard whereas in case of different nutrient sources, 100 per cent recommended dose of fertilizerwas found better.

Abstract

Afield experiment was carried out for two years from 2020-2022 on maize to evaluate the effect of seed priming, tillage practices and nutrient management on growth parameters and yield of the crop in rainfed conditions. The experiment was laid in a factorial randomized block design, consisting of three factors. Factor A (Tillage practices) consisted of Conventional tillage (CT), Conventional tillage+ mulch (CT+M) and Zero tillage+ mulch (ZT+M); Factor B (Seed priming) consisted of Hydropriming and micronutrient priming; Factor C (Nutrient management practices) consisted of the recommended dose of fertilizers (RDF) and Integrated nutrient management. An additional treatment of control was also kept as an independent module for a general comparison of results. Significant differences in growth parameters and yield were observed as affected by tillage practices and nutrient management. All growth parameters and yield were found to be significantly better under conventional tillage+mulch (CT+M) as compared to other tillage practices. Moreover, integrated nutrient management proved to be comparatively superior to recommended dose of fertilizers in terms of growth studies as well as the yield of maize.

Abstract

A field trial was conducted during rabi season of 2020-2021 at Water Management Farm, CSKHPKV, Palampur to find out the effect of irrigation levels and management practices on growth and yield of different Brassica species. The experiment was laid out in split plot design with two irrigation regimes viz. irrigation at 30 days after sowing (DAS) and at flowering (two irrigations) and irrigation at pre-sowing, 30 DAS and at flowering (three irrigations) in main plots, and combinations of three brassica species viz. Brassica oleracea ‘KBS 3’, Brassica juncea ‘RCC 4’and Brassica napus ‘GSC 7’and two management practices viz. conventional and natural farming in sub plots. The results revealed that application of three irrigations significantly increased the plant height, dry matter accumulation, seed and stover yield of Brassica species as compared to two irrigations. Brassica oleracea ‘KBS 3’ outperformed all other Brassica species where as conventional management proved superior over natural farming on mean basis. However, application of two irrigations in Brassica oleracea ‘KBS 3’ under conventional management, being at statistically at par with three irrigations was found best in terms of seed yield besides saving precious irrigation water.

Abstract

The effect of continuous application of fertilizers and amendments on maize and wheat yield in an acid Alfisol>/i> during 2019-20 was evaluated in a field experiment at the research farm of the Department of Soil Science, CSKHPKV Palampur (HP). The field experiment was conducted on a pre-established long-term fertilizer experiment (1972-73) which comprised of ten treatments up to 1980-81. The eleventh treatment, consisting of 100 per cent NPK (-S) was introduced in kharif, 1981. Thereafter, another treatment, consisting of Beejamrita, Jeevamrita and Ghanajeevamrita (Natural Farming) was introduced in kharif, 2019. The soil of the experimental area was silty clay loam and classified taxonomically as “Typic Hapludalf”. Continuous application of fertilizers and amendments for forty-seven years significantly influenced the yield of maize and wheat. The highest productivity of maize as well as wheat was recorded in the treatment comprising 100 per cent NPK + FYM and was statistically comparable with 100 per cent NPK + lime. Continuous application of N alone over the decades resulted in no yield. However, potassium and sulphur omission from the fertilization schedule for more than four decades resulted in drastic reduction in the yield. The grain and stover/straw yield recorded in natural farming plots was significantly lower as compared to other treatments except control

Abstract

A field experiment was conducted during kharif 2021 at the Research Farm of Department of Agronomy, College of Agriculture, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the effectiveness of a new post-emergence broad-spectrum herbicide GOD H008 (Bispyribac sodium 5% SC+ Pyrithiobac sodium 12.5% SG) to control mixed weed flora in direct-seeded upland rice (Oryza sativa L). The experiment was laid out in Randomized Block Design with three replications and seven weed control treatments. The treatments consisted of three doses of GOD H008 (Bispyribac sodium 5% SC+ Pyrithiobac sodium 12.5% SG) viz. 375ml/ha, 500ml/ha and 625ml/ha, bispyribac sodium 250ml/ha, pyrithiobac sodium 625ml/ha, hand weeding (weed free) and untreated check respectively. The predominant weed flora present in the experimental field was Ageratum conyzoides, Cyperus rotundus, Commelina benghalensis, Echinochloa colona, Digitaria sanguinalis and Synedrella nodiflora. Application of new herbicide combination product GOD H008 (Bispyribac sodium 5% SC+ Pyrithiobac sodium 12.5% SG) 500ml/ha being statistically at par with GOD H008 (Bispyribac sodium 5% SC+ Pyrithiobac sodium 12.5% SG) 625ml/ha and bispyribac sodium 250ml/ha resulted in significantly lower total weed count, total weed dry weight and highest weed control efficiency as compared to other weed control treatments. Significantly highest grain and straw yield were recorded with the application of GOD H008 (Bispyribac sodium 5% SC+ Pyrithiobac sodium 12.5% SG) 500ml/ha at harvest and this treatment was closely followed by GOD H008 (Bispyribac sodium 5% SC+ Pyrithiobac sodium 12.5% SG), 625 ml/ha.

Abstract

A field experiment was conducted during kharif 2021 at the Research Farm of Department of Agronomy, College of Agriculture CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the bio-efficacy of flumioxazin against mixed weed flora in grassland. The experiment was laid out in Randomized Block Design with three replications. The experiment consisted of nine weed control treatments viz., flumioxazin 150 g/ha, 200 g/ha, 250 g/ha, 300 g/ha, 500 g/ha, oxyfluorfen 1000 g/ha, weed free, glyphosate 4000 g/ha and untreated control. The major weeds in the experiment area were Ageratum conyzoides, Erigeron canadensis, Bidens pilosa, Cynodon dactylon, Cyperus sp., Digitaria sanguinalis and Plantago lanceolata. The results revealed that post-emergence application of flumioxazin 500 g/ha, which was statistically at par with flumioxazin 300 g/ha, flumioxazin 250 g/ha, flumioxazin 200 g/ha and glyphosate 4000 g/ha were quite effective in controlling weeds with higher weed control efficiency. Application of flumioxazin 300 g/ha resulted in significantly higher fresh and dry herbage yield of grasses which was at parwith flumioxazin 500 g/ha, 250 g/ha and 200 g/ha.
