Experiment Title Effect of spacing and sowing time in cotton (Gossypium hirsutum L.) under rainfed conditions
Research Type Departmental Research
Experiment Background India ranks second in area and production of cotton in the world. It plays a vital role in the national economy by contributing 29.8% India’s agricultural gross domestic production. Among the different cotton growing countries in the world, India ranks second next to china with regards to production. In India, cotton is cultivated in an area of 132.9 lakh hectares with a production of 352.5 lakh bales of seed cotton (170 kg/bale) with a productivity of 451 kg/ha (Agricultural Statistics at a Glance, GoI, 2022). Cotton is a sub-tropical plant having indeterminate growth habit. Among various agronomic practices to boost up crop productivity, plant population is one of the most important factors for efficient utilization of available resources. The manipulation of plant density and crop geometry is a time tested agronomic technique for achieving higher crop yield. In wider spacing, yield reduces due to less number of plants per unit area and closer spacing reduces yield due to competition within the plants (Patel et al., 2021). Suitable sowing time is a non-monetary important agronomic practice to increase the yield of any crop. Sowing time provide favourable climate conditions to crop at different growth stages of crop that resulted in production of higher crop yield. Keeping these points in view, an investigation was undertaken to effect of spacing and sowing time to enhance the productivity of cotton with existing plant architecture.
