Growth and yield of ELS cotton as influenced by method of planting, intercrops and fertilizer management in summer season

A field experiment was carried out during summer 2019 in field No. NA 2 at Eastern Block farm, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during 2019 to find out the establishment techniques of ELS cotton, suitable intercrops in between cotton rows and fertilizer management. The experiment field was geographically located in western agro climatic zone of Tamil Nadu at 11oN latitude and 77oE longitude and at an altitude of 426.7 meters above the Mean Sea Level (MSL). The texture of the experimental site was sandy clay loam. The experiment was laid out in randomized block design consist of two crop establishment methods viz., transplanted cotton and direct seeded cotton and three different levels of fertilizer viz., 75%, 100%, 125% NPK and three intercrops viz., green gram, black gram and onion. Observations were recorded for survival percentage, growth and yield characters of cotton. Assessment of intercrop productivity. The results revealed that transplanted seedlings improved the survival rate of 20.45 % over the normal direct seeded cotton. Transplanted cotton seedling intercropped with black gram along with 125% fertilizer level gave higher growth and seed cotton yield of 3392.91Kgha-1.
