Effect of different tillage practices on the growth and yield of cotton (Gossypium hirsutum L.)

摘要

A field experiment was conducted from 2001 to 2003 at Punjab Agricultural University, Ludhiana to evaluate the effect of different tillage practices on the growth and yield of cotton during the kharif seasons. Four treatments consisted of no tillage,conventional tillage, deep tillage and deep+conventional tillage. The results revealed that deep tillage produced significantly higher seed cotton yield (1431 kg/ha) which was 78.21 and 53.05% more than no tillage (803 kg/ha) and conventional tillage (935 kg/ha), respectively. Similarly, in deep tillage 82.63 and 28.15% higher number of bolls per plant was recorded as compared to no tillage and conventional tillage, respectively. In deep tillage, the seed cotton yield per plant was 92.5 g which was significantly higher as compared to no tillage and conventional tillage but at par with deep+conventional tillage.
