Resources use efficiency in Bt-cotton (Gossypium hirsutum L.) to nutrient management practices under supplemental irrigations
Author(s): Sangh Ravikiran and AS Halepyati
Abstract: Experiment was laid out in split plot design with three fertilizer levels in main-plots and six foliar applications of nutrients in sub-plots with three replications at Agricultural College Farm, Raichur on vertisol during 2010-11. Effect of nutrient management practices differed significantly on efficiency of resources in cotton. Fertilizer levels of 156.25: 93.75:93.75 kg N:P2O5:K2O ha-1 with 12.5 t ha-1 of farm yard manure recorded significantly higher seed cotton yield (17.1 q ha-1) over other fertilizer levels. Besides, foliar applications of 0.5 per cent tracel (Zn, Fe, Mn and B) recorded significantly higher seed cotton yield (17.5 q ha-1) against other treatments. In addition, interaction effect due to fertilizer levels of 156.25: 93.75:93.75 kg N:P2O5:K2O ha-1 with 12.5 t ha-1 of farm yard manure with foliar applications of 0.5 per cent tracel recorded significantly higher seed cotton yield (19.9 q ha-1), besides it was on par with fertilizer levels of 156.25: 93.75:93.75 kg N:P2O5:K2O ha-1 with 12.5 t ha-1 of farm yard manure with foliar applications of 10 ppm planofix when compared to rest of the other treatment combinations.
