Abstract
A series of experiments were conducted at Sindh Agriculture University, Tandojam. The experiment was laid out in Randomized Complete Block Design (RCBD) with factorial arrangement consisting four replications and repeated in the 2nd year. The treatments consisted crop two sequences [(C1= Cotton (before legume) and C2= Cotton (after legume)] and varying fertility levels (F1=150-50, F2=100-50 and F3=150-50 NP Kg ha-1). The berseem was cultivated as leguminous crop in the sequence. The crop sequences revealed that the cotton crop sown after legume produced tall plants (99.41 cm), higher production of monopodia plant-1 (2.68), sympodia plant-1 (14.10), more bolls plant-1 (24.83), heavier seed index (6.83 g), maximum GOT (34.47%), better staple length (28.83mm), higher oil content (22.87%), superior seed cotton yield (2428 kg ha-1) and N-uptake increased upto 91.17 kg ha-1. The incorporation of NP fertilizer significantly affected crop parameters. Among the tested fertilizers
