GROWTH AND YIELD RESPONSE OF MUSTARD TO LEAF CLIPPING

Abstract

The experiment was conducted at Sher-e-Bangla Agricultural University Farm, Dhaka during the period from October 2017 to February 2018 to study the growth and yield response of mustard to leaf clipping. The treatment consisted of three variety viz. V 1 =BARI Sarisha-14,V 2 =BARI Sarisha-15 and V =BARI Sarisha-17 and five leaf clipping viz. C 0 = No leaf clipping, C 1 = Clipping of 1 3 st and 2 nd leaf at main stem, C = Clipping of 2 nd and 3 rd leaf at main stem, C 3 =Clipping of 3 rd and 4 leaf at main stem, C 4 = Clipping of 4 th and 5 th leaf at main stem. The experiment was laid out in split plot design with three replications. Significant effect was observe on the basis of plant height (cm), branches plant -1 , avobe ground dry matter plant , length of siliqua(cm) siliquae plant -1 , seeds siliqua -1 , 1000 seed weight (g), yield (t ha ), stover yield (t ha -1 ), biological yield (t/ha) and harvest index. Results revealed that the highest length of siliqua (5.07 cm), siliqua plant -1 (102.4), seeds siliqua (26.67), thousand seed weight (3.82 g) ), total yield (1.86 t ha -1 th -1 -1 -1 ),Biological yield(5.78 t ha ) and harvest index (64.62%) was obtained from BARI Sarisha-17 with clipping of 2

and 3 rd leaf on main stem at flower initiation stage while the lowest (1.007 t ha ) from BARI Sarisha-14 with clipping of 4 th and 5 th leaf on main stem at flower initiation stage. -1 2 -1 nd
