Influence of Integrated Nutrient Management on Growth and Yield of Bt Cotton (Gossypium hirsutum L.) Hnder Dry Farming Condition

The field experiment was conducted during kharif seasons of 2008–2013 on medium black soil at Dry Farming Research Station, Junagadh Agricultural University; Targhadia to study the effect of integrated nutrient management (INM) techniques on seed cotton yield, economics and soil physico-chemical properties under dry farming condition. The experiment was laid out in randomized block design with ten different treatment combinations comprising of organic and inorganic fertilizers (NPK), gypsum, castor cake, compost and vermi-compost replicated in a thrice. The experimental result showed that the significantly higher seed cotton yield (2298 kg/ha) and highest net return (98289/ha) were recorded under treatment T₉ (80 kg/ha + 10 tones compost/ha + 500 kg castor cake/ha + bio-fertilizer-Azotobacter + PSM). The highest number of branches/plant, numbers of balls/plant and plant height (cm) were also recorded under treatment T₉.
