Influence of foliar nutrition on leaf reddening of Bt cotton under rainfed condition

Abstract

A field experiment was conducted on farmers field at Kautha, Tq. Kandhar. Dist. Nanded during Kharif 2018-19 on Vertisol to find out the effect of foliar nutrition on leaf reddening of Bt cotton under rainfed condition. The experiment was laid out in Randomized Block Design with eight treatments and replicated thrice. The result revealed that application of 100 per cent RDF (100:50:50 kg NPK ha-1) in combination with foliar spray of DAP@ 2% + KNO3 @ 1% + MgSO4@ 1% and micronutrient Grade II @ 0.5% at flowering, boll formation and boll development stage recorded the maximum leaf nutrient content and total chlorophyll content and helpful in minimize the anthocyanin content and leaf reddening index in Bt cotton under rainfed condition.
