Abstract

A field investigation was conducted during Kharif season The experiment was laid out in split plot design with three replications. There were twelve treatment combinations comprising three plant geometries viz., 90 cm x 60 cm, 120 cm x 45 cm and 180 cm x 30 cm and four nutrient levels viz., 80:40:40, 100:50:50, 120:60:60 kg NPK/ha and 75 % RDF + 5 t FYM/ha. The plant geometries were allotted to main plot and nutrient levels were accommodated in sub plots. The plant geometry of 90 cm x 60 cm has recorded significantly higher number of sympodias per plant, the number of picked bolls per plant and seed cotton yield per plant over 120 cm x 45 cm and 180 cm x 30 cm. The seed cotton yield per hectare was also higher in plant geometry of 90 cm x 60 cm than 120 cm x 45 cm and 180 cm x 30 cm. The application of nutrient level i.e. 120:60:60 kg NPK/ha was found superior for enhancing growth parameters viz., plant height, number of leaves, leaf area and dry matter. The application of 75% RDF + 5 t FYM/ha recorded significantly higher seed cotton yield per hectare. Based on the results it can be concluded that the yield attributes of Bt cotton were improved in plant geometry of 90 cm x 60 cm. The seed cotton yield of Bt cotton was significantly higher in plant geometry of 90 cm x 60 cm than 120 cm x 45 cm and 180 cm x 30 cm which recorded 23 % and 21 % higher over 120 cm x 45 cm and 180 cm x 30 cm, respectively. Application of 75% RDF + 5 t FYM/ha to Bt cotton was significantly superior than rest of all other treatments which recorded 14, 9 and 5.5 per cent higher yield over 80:40:40 kg NPK/ha, 100:50:50 kg NPK/ha and 120:60:60 kg NPK/ha, respectively.

Abstract

The experiment was laid out in Randomized Block Design with five sowing dates viz., S₁ -22^nd June, S₂ -29^th June, S₃ -6^th July, S₄ -13^th July and S₅ -20^th July and four replications. The observations on initiation of tikka diseases and per cent disease intensity were recorded periodically at an interval of one week after the occurrence of these diseases. The first incidence of tikka disease was observed at 30 DAS in S₁, S₂, S₃, S₄ treatments and at 56 DAS in S₅. The maximum incidence in all the five dates of sowing in Kharif season was observed between 65 to 79 DAS. Favourable climatic conditions for disease incidence and development were temperature ranged between 26°C to 32°C and relative humidity ranged between 61-79 per cent. The data revealed that in case of tikka disease there was positive significant correlation between disease intensity and maximum temperature (0.66), morning relative humidity (0.34), evaporation (0.39) and bright sunshine hours (0.65), whereas minimum temperature (-0.55), evening relative humidity (-0.69), wind speed (-0.73) and rainy days (-0.26) showed negatively significant correlation with disease intensity in Kharif season and wind speed, rain and rainy days were responsible for development tikka disease intensity. From the multiple regression analysis here it is concluded that the tikka disease severity was significantly related with wind speed (-5.53), rain (0.12) and rainy days (-4.46) and these factors were found to be significantly superior among the all weather parameters.

The gross and net plot size of experimental unit was 6.4 m × 3.6 m and 5.4 m × 2.4 m, respectively with a row spacing of 30 cm and plant spacing as 10 cm. All recommended agronomical practices were adopted as per schedule. First date (D₁) and second date (D₂) crop sown in MW 40 and MW 41 recorded significantly higher leaf area index than other dates of sowing. The various growth characters like, plant height, spread of plant were higher in second (D₂) date than other dates of sowing. Mean number of branches per plant and dry matter accumulation was found significantly superior in first (D₁). D₁ which required less number of days for 50 per cent flowering and more days for maturity. The various yield attributing characters viz., number of capsules plant^-1, weight of capsules plant^-1, number of seeds capsule^-1, seed weight plant^-1 and thousand seed weight were found higher in first date of sowing. D₁ recorded significantly higher seed yield, straw yield, biological yield and harvest index than other treatments. The various growth characters viz., number of branches plant^-1, spread of plant, total dry matter accumulation were substantially more in cv. GARIMAexcept plant height, which was recorded more in cv. RLC-4. Number of days required to 50 per cent flowering were also lesser in cv. GARIMA. The number of days required for physiological maturity were more in cv. KIRAN. Remarkably, the various yield attributes like mean number of capsule plant^-1, weight of capsules, mean number of seeds capsule^-1, seed weight plant^-1, weight of straw plant^-1 and thousand seed weight were higher in cv. GARIMA over other cultivars. Among the cultivars, Garima recorded higher seed yield, straw yield, and biological yield as well at harvest index.

Abstract

An experiment was laid out in Randomized Block Design with five sowing dates viz., S₁ -22^nd June, S₂ -29^th June, S₃ -6^th July, S₄ -13^th July and S₅ -20^th July and four replications. The observations on initiation of rust diseases and per cent disease intensity were recorded periodically at an interval of one week after the occurrence of these diseases. In rust disease maximum temperature (0.59), morning relative humidity (0.33), evaporation (0.33) and bright sunshine hours (0.55) showed positive correlation with disease intensity. Whereas, minimum temperature (-0.44), evening relative humidity (-0.58) and wind speed (-0.63), showed negatively significant correlation with disease intensity in Kharif season. Other climatic factors i.e. rainfall showed no significant correlation with disease intensity. The morning relative humidity and bright sunshine hours were correlated for rust disease incidence. The result from all the relevant observations indicated that the morning relative humidity (2.87) and bright sunshine hours (5.65) during the crop growing period was found to be highly significant weather conditions for rust disease development among the all other weather parameters. The multiple regression equation developed from the data in this regard is as : Y= -257.591 +2.879RH-I(W-1) +5.651BSS(W-1).

Abstract

The field experiment was laid out in Split Plot Design with three replications. The treatments consisted of 6 dates of sowing D₁: 40th MW, D₂: 41st MW, D₃: 42nd MW, D₄: 43rd MW D₅: 44th MW and D₆: 45th MW as main plot treatment and 3 cultivars V₁: Kiran V₂: Garima V₃: RLC-4 as sub plot treatment at college of Agriculture latur during Rabi season. The data presented revealed that duration required for emergence ranged from 6 days under different date of sowing in different cultivars tested whereas in P₃ (branching to flowering) and P₄ (flowering to capsule formation) which are critical growth stages from the seed yield point of view, ranged from 17 to 22 days and 22 to 27 days, respectively. The data revealed that, the total heat requirement during the crop life cycle ranged from 1221 ⁰Cd to the 1514 ⁰Cd. The heat load, reported a decreasing trend as the sowing time was delayed. Decreasing trends in accumulated growing degreedays was observed with successive delay in sowing of all the cultivars. The data further reveled that the heat requirement was almost double, during reproductive growth stages than the vegetative growth stages. As regards the total thermal requirement of cv. KIRAN, it required maximum thermal units as 1514 ⁰Cd in first (D₁) date of sowing at MW 40. This cultivar recorded the lowest thermal requirement as 1334 ⁰Cd in sixth (D₆) date of sowing at MW 45. Cultivar Garima required maximum thermal units as 1270 ⁰Cd when linseed crop was sown in MW 40. This cultivar recorded the lowest thermal units as 1334 ⁰Cd under (D₆) treatment (MW 45). Cultivar RLC-4 recorded the highest thermal requirement of 1416 ⁰Cd in (D₁) MW 40. This cultivar recorded the lowest thermal unit as 1221 ⁰Cd under sixth (D₆) date of sowing at MW 45. The photosynthetic active radiation (PAR) recorded periodically in different treatments data revealed that at 30 DAS the minimum and same value were recorded in almost all the treatments. However, as the crop growth advanced the absorption rate increased abruptly, in all the treatments except D₄ during the period of 40-50 DAS. The increase in absorbed PAR was almost higher in treatments D₁ and D₂, which persisted up to 70 DAS. Thereafter a gradual decreased in PAR absorption was noticed till 110 DAS i.e., physiological maturity. However in treatment D₄ the abrupt decrease during 90 to 100 DAS was also noticed. The increased PAR from 40 DAS to 70 DAS indicated a proper source sink relationship because of proper canopy development.

Abstract

An experiment was laid out in a split plot design with three replications and twelve treatment combinations formed due to (A) three sowing dates viz., 49^th MSW (D₁), 50^th MSW (D₂), 51^st MSW (D₃), four potash levels, 0 kg K₂O ha^-1 (K₁), 25 kg K₂O ha^-1 (K₂), 50 kg K₂O ha^-1 (K₃) and 75 kg K₂O ha^-1 (K₄). The soil of experimental field was deep black clayey in texture, low in available nitrogen (148.25 kg ha^-1), medium in available phosphorus (16.64 kg ha^-1) and very high in potassium (432.58 kg ha^-1) with slightly alkaline in reaction (pH 8.1). The chickpea was sown on various sowing dates viz., 10^th, 17^th and 24^th December 2009. The treatments of potassium levels along with recommended dose of fertilizer (25:50:00 kg NPK ha^-1) was given at the time of sowing. The seeds were treated with rhizobium culture @ 25 g per kg seeds. The value of yield attributes such as number of pods per plant (46.99), weight of grain per plant (12.75 g) and weight of 100 seeds (26.28 g) were significantly higher when chickpea was sown on 10^th December over crop sown on 24^th December but it remained at par with 17^th December sown chickpea. The yield attributes viz., number of pod, weight of pod, weight of grains per plant and 100 seed weight (g) were significantly the highest due to application of 50 kg K₂O ha^-1. The protein content in the grain was significantly increased with increased potash levels.The interaction effect between sowing dates and potash levels on growth, yield and quality of chickpea were non-significant. Thus, from the results of the present investigation it is concluded that for Rabi chickpea (cv. DIGVIJAY) on deep black soil under irrigated conditions, 10^th December sown crop along with application of 50 kg K₂O ha^-1 through muriate of potash at the time of sowing would be the best proportion for higher productivity.

Abstract

The experiment was laid out in Rabi season(2009-2010 and 2010-2011). IRGA instrument (LI-6400XT) was used for estimation different microclimatic parameters of the crop within the height of 2 mt. In general, during both seasons, there was a rapid increase in mean stomatal conductance from early growth stage to 56 days and thereafter it gradually decreased towards maturity of the crop.Highest mean values of stomatal conductance were recorded at 56 DAP interval as 0.38 and 0.52 mol. m^-2 s^-1 in 2009 and 2010, respectively. Further, there was also gradual increase in mean stomatal resistance from early growth stage towards maturity of the crop. Lowest mean values of stomatal resistance were recorded at 28 DAP interval as 4.21 and 3.28 mol. m^-2 s^-1 in 2009 and 2010, respectively. Increased stomatal conductance appeared to be the reason for the first peak whereas for the second peak non stomatal characters may be responsible. Stomatal resistance governs photosynthesis and transpiration. Decrease in soil moisture content increased stomatal resistance. High temperature was associated with decreased stomatal resistance. Stomatal resistance is affected by many factors including PAR, leaf age, air temperature and the CO₂ concentration. Analysis of the relationship between PAR, leaf age, air temperature and the CO₂ concentration at the various growth stages for the different treatments showed that 1.2 IW/CPE ratio and planting on 44th MW with mulching treatment proved to be superior to the other treatments. It is observed from the data that during both the years of experimentation, of haulm yield (q ha^-1), mulching produced significantly higher mean values of these haulm yield (q ha^-1) than without mulching. The haulm production which was reduced by the effect of water stress on stem growth and reduction in number of branches, as well as to a limited extent on the tubers themselves.

Abstract

A field investigation entitled studies on physio-chemical properties of soil under nutritional requirement studies in soybean was conducted during Kharif season 2009-10 at AICRP for Dryland Agriculture, M.A.U., Parbhnai. The experiment was laid out in Randomized Block Design (RBD) with three replications. There were eight treatments viz., T₁-75 per cent RDF without FYM, T₂-75 per cent RDF with FYM @ 5 t/ha, T₃-100 per cent RDF without FYM, T₄-100 per cent RDF with FYM @ 5 t/ha, T₅-125 per cent RDF without FYM, T₆-125 per cent RDF with FYM @ 5 t/ha, T₇-FYM @ 10 t/ha and T₈-Absolute control. The grain yield and straw yield were significantly more in treatments T₄ (100% RDF + 5 t FYM/ha). Based on the results it can be concluded the treatment T₄ (100 % RDF + 5 t FYM/ha) was found beneficial in improving growth, yield attributes, yield of soybean as compared to other treatments, Treatment T₄ (100 % RDF + 5 t FYM/ha) also recorded double yield than absolute control and the physio-chemcial properties were improved with FYM application.

Abstract

The experiment was laid out in Factorial Randomized Block Design with twelve treatment combinations, formed due to three varieties (Tapi (JLT-7), Phule Til-1and Hawari) and four levels of fertilizer (0, 12.5 + 6, 25+12.5 and 37.5 + 18.5 N + P₂O₅ kg/ha) replicated three times. Amongst the three varieties studied, the mean values for height, spread of plant, number of functional leaves were more in the variety Phule Til-1 at 60 days. The total dry matter accumulation per plant, straw yield, straw to grain ratio were also more in Phule Til-1. the number of capsules and branches per plant, number of seeds per capsule, thousand grain weight, grain to empty capsule ratio and harvest index were significantly more in variety Tapi (JLT-7). Due to expressions of higher order for yield contributing characters, the variety Tapi (JLT-7) produced significantly more grain yield and oil yield. The protein content in the varieties was found to be non-significant. The variety Hawari is early type and required less days for maturity as compared to the rest of the varieties. The growth attributes viz., plant height, spread number of functional leaves and dry matter accumulation per plant were influenced by different fertilizer levels. The values of the yield attributes viz., number of capsules, grain weight per plant and thousand grain weight were increased with every successive increased level of fertilizer and was maximum with 37.5 kg N+18.5 kg P₂O₅ ha. The grain (9.93q/ha), straw (20.97 q/ha) and oil (4.68 q/ha) yields obtained due to the application of 37.5 kg N+18.5kg P₂O₅/ha were the highest and significantly more than the rest of the lower levels.

Abstract

Factorial randomized black design was laid out with twelve treatment combinations, formed due to four levels of fertilizer (0,12.5+6,25+12.5 and 37.5+18.5 N+p₂0₅ kg/ha), three varieties (Tapi (JLT-7), Phule Til-1and Hawari) and replicated three times. Amongst the three varieties studied, the mean values for height, spread of plant, number of functional leaves were more in the variety Phule Til-1 at 60 days. The total dry matter accumulation per plant, straw yield, straw to grain ratio were also more in Phule Til-1. The number of capsules, branches per plant, number of seeds per capsule, thousand grain weight, grain to empty capsule ratio and harvest index were significantly more in variety Tapi (JLT-7). Due to expressions of higher order for yield contributing characters, the variety Tapi (JLT-7) produced significantly more grain yield and oil yield. The protein content in the varieties was found to be non-significant. The variety Hawari is early type and required less days for maturity as compared to the rest of the varieties. The growth attributes viz., plant height, spread number of functional leaves and dry matter accumulation per plant were influenced by different fertilizer levels. The values of the yield attributes viz., number of capsules, grain weight per plant and thousand grain weight were increased with every successive increased level of fertilizer and was maximum with 37.5 kg N+18.5 kg P₂O₅ ha. The grain (9.93 q/ha), straw (20.97 q/ha) and oil (4.68 q/ha) yields obtained due to the application of 37.5 kg N+18.5 kg P₂O₅/ha were the highest and significantly more than the rest of the lower levels.
