Babar, J.A.
An experiment, to study the Response of Cotton Under High and Low NP Levels on the growth and yield of cotton variety Shahbaz-95 was conducted Cotton Section, Agriculture Research Institute, Tandojam during summer 2000- 2001. The experiment was laid out in randomized complete block design, ultimate plot size 10m x 7m, having four replications. The fertility levels were; F1=0-0, F2=56-28, F3=112-56 and F4=224-112. All the traits were highly significantly affected by fertility levels. Application of maximum amount of NP fertilizer kg/ha produced taller plants of 91.20 cm. more number of sympodial branches (15.46) per plant, higher number of bolls (26.47) per plant. Maximum seed cotton yield 60.18 g per plant and per hectare (1929.34 kg), higher seed index (7.71 and also higher GOT % (32.98) in cotton variety Shahbaz-95 were obtained under higher level of NP kg/ha under agro climatic conditions of Tandojam.
