Experiment code SRT Agro. IV
Experiment Title Feasibility of different intercrops in Bt Cotton hybrid
Research Type State Trial
Experiment Background Cotton (Gossypium sp.) is one of the most important fibre and cash crop in India belongs to Malvaceaefamily and known as “King of Fiber” and “White gold” plays a prominent role in the rural, national and international economy. It is grown mostly for fibre used in the manufacture of cloths for mankind. India is a major producer of cotton. India stands first position in area and third in its production. In India it is grown over an area of 115.13 lakh hectares with production of 375 lakh bales and productivity of 489 kg/ha. Intensification of cotton based cropping system with intercrops was successful as a component in the system have different nutrient and moisture requirement, varied feeding zones in the soil profile, differential growth duration for enabling the utilization of natural resources optimally. Intercropping of legumes is an important aspect for biological farming system not only for weed control, but also in reducing the leaching of nutrients, pest control and in reducing soil erosion. Keeping all the views in mind an experiment is planned to find out the effect of different intercrops on growth and yield attributes on American cotton.
