 ABSTRACT

A field experiment was conducted during kharif, 2016-17 on black cotton soils of RARS Farm, Nandyal to study the effect of sowing dates and phosphorus levels on growth, yield attributes and yield of maize. The experiment comprised of four main plots viz., crop sown during I FN of July, II FN of July, I FN of August and II FN of August and three sub plots viz., 75% recommended dose of phosphorus, 100% recommended dose of phosphorus and 125% recommended dose of phosphorus. The results revealed that all the growth parameters, yield attributes and yield was significantly influenced with the sowing dates. However, the influence of phosphorus levels on growth and yield parameters of maize was recorded to be non significant.

Key words: Sowing dates, Phosphorus levels, Vertisols, Cobs, Kernel, Stover, Yield and Maize
