ABSTRACT
In Pakistan, the research work on cotton since started from the independence and many of the cultivars were introduced and evolved. But the fiber quality and seed cotton yield up to now till is poor in quality as compared to other developed countries. A judicious combination of manures and fertilizers depending upon the availability, the type of the soil and crops to be grown would not only maximize the crop production and improve the quality of agricultural products but would also maintain the fertility, productivity and overall health of the soil for posterity. So, keeping in view the beneficial effects of organic sources i-e compost and farm yard manure (FYM), a field experiment was planned with the objectives to study the comparative effect of organic sources on cotton growth and yield and to evaluate the comparative performance of different BT cotton variety. The treatments were T0: Control T1: FYM @10 tons ha-1, T2: Compost @10 tons ha-1 and T3: FYM @10 tons ha-1+ Compost @10 tons ha-1. Three BT cotton varieties (BT-142, Lala zar and BT-786) were tested against the organic sources applications impacts. The application of compost and FYM in combined increased the physical parameters number of bolls per plant, plant height, sympodial branches, monopodial and seed cotton yield as compared to compost and FYM individual application. Among the all varieties, Lalazar performed better by producing maximum monopodial and sympodial branches, plant height, bolls per plant and seed cotton yield as compared to BT-142 and BT-786 while minimum performance was observed in BT-142.
