Abstract: The experiment was conducted to study the effect of fertigation on yield, quality and soil nutrient status under cotton grown in Vertisol at Akola during kharif season of 2009-10 to 2011-12. The experiment consists of various levels of fertilizers through drip fertigation along with Zn laid out in randomized block design with three replications. The results of the present experiment revealed that, the maximum values of nutrient uptake, fibre quality parameters, economics and highest seed cotton (18.19 q ha-1) and stalk (41.89 q ha-1) yield was recorded with 100% RD (100:50:50 kg N:P2O5:K2O ha-1) along with combined application of Zn (4 kg ha-1) + Fe (5 kg ha-1) through drip from water soluble fertilizers (WSF). The higher values of N, P, K Zn and Fe was recorded with 100 % recommended dose of fertilizer alongwith combined application of Zn (4 kg Zn ha-1) + Fe (5 kg Fe ha-1) through soil application from conventional fertilizer (Urea,DAP, MOP). Application of 75% RD + (3 kg ha-1) + Fe (3.75 kg Fe ha-1) through drip (WSF) recorded higher Gross monetary returns (Rs. 74914 ha-1), net monetary returns (Rs. 34447 ha-1) and B:C ratio (1.85). The performance of treatment 75% RD + Zn (3 kg ha-1) + Fe (3.75 kg ha-1)through drip from water soluble fertilizers was found at par with the treatment giving the highest yield showing its importance in saving of 25% N, P2O5, K2O, Zn and Fe through drip from water soluble fertilizers.
