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.

Abstract

The experiment was laid out in Split Plot Design with three replications, with eighteen treatment combinations of date of sowing D₁ - 7^th October (MW 40), D₂ - 14^th October (MW 41), D₃ - 20^th October (MW 42), D₄ - 25^th October (MW 43), D₅ - 30^th October (MW 44) and D₆ - 5^th November (MW 45) as main plot treatments, and three cultivars (V₁ - Kiran, V₂ - Garima and V₃ - RLC- 4) as sub plot treatments. 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.
