Abstract

A field experiment was carried out during summer season of 2012 at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal to study the effect of N arid K application in splits along with or without Azophos on the yield parameters and yield of cotton var. SVPR 4. The experiment was laid out in randomized block design with three replications. The results revealed that application of 25% N and K as basal and 25% N and K as top dress on 40 DAS and 50% N and K on 60 DAS along with 4 kg of azophos biofertilizer registered improved yield attributes and higher seed cotton yield of 1565 kg/ha.
