Abstract
An experiment was conducted at Cotton Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MS) during kharif season of 2009-10 on medium deep black soil under factorial randomized block design with fifteen treatment combinations replicated four times. The treatments imparted to cotton crop were 5 split applications of nitrogen and potassium and 3 levels of fertilizer. The result revealed that application of N and K in six splits i.e. 25% as basal and remaining in five equal splits starting from 15 DAS at 15 days interval significantly improved seed cotton yield, GMR, NMR and B:C ratio. Among the fertility levels RDF i.e. 50:25:25 kg NPK ha-1 was found to be effective in this respect. While fiber quality parameters remained unchanged due to fertilizer levels and split applications of nitrogen and potassium.
