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

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 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

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

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.
