EI<'FECT OF VARIETY AND FI<:RTLIZER MANAGEMENT ON YIELD AND YIELD CONTRIBUTING CHARACTERS OF COTTON

Abstract

A field experiment was conducted at Regional colton Research, Training and Seed multiplication Hum, Jagadishpur, Jessore during July 2003 10 March 2004 to observe the effect or variety and fertilizer management on yield and yield contributing characters of cotton. The experiment was conducted in Randomized Complete Block Design (factorial) replicated four times. The treatments consisted of two colton cultivars and three fertilizer management. It was observed that the number of squares plant", number of flowers plant", number of bolls plant", seed colton and lint yield, seed index and lint index varied significantly due to variety and fertilizer management of cotton. However, seed cotton yield plant" and ginning percent were significant for variety but not for fertilizer management. Interaction effect of variety and fertilizer management on the number of squares plant", number of flowers plant", number of bolls plant', seed colton yield planr' and seed index were significant but other parameters were not significant Seed cotton yield (3712 kg ha') and lint yield (1540 kg ha") was higher in CB-5 in comparison to CB-9 (328917 and 1139.04 kg ha respectively) and which were 12.87% more seed cotton yield and 35.22% lint yield over variety C13-9. The highest seed cotton yield «4088 kg ha') and lint yield (1563 kg ha') were obtained from farmers' practice. Ginning percentage was significantly influenced due to variety. Fertilizer management using farmers' practice gave maximum yields (4308.50 and 1787.60 kg lint ha' with variety CB-5). Ginning percentage of variety C8-5 was 41.50 which were significantly higher than that ofCB-9 (36.15)
