EFFECT OF LEAF CLIPPING AND DIFFERENT FERTILIZER DOSES ON THE YIELD OF MUNGBEAN

Abstract

A field experiment was conducted at the experimental farm of Sher-e-Bangla Agricultural University (SAU), Dhaka, during the period from March 2007 to June 2007 to study the in uluence of different leaf clipping and fertilizer doses on growth and yield of mungbcan. The trial comprised four treatments on leaf clipping (No removal, removal of new leaves developed after first flowering, removal of subtending leaves beneath the inflorescences and removal of empty leaves), and(.three treatments on fertilizer doses per hector (10 kg N + 20 kg P205 + 15 kg K20. 20 kg N + 40 kg P205 ± 30 kg K20 and 30 kg N + 60 kg 13205+ 45 kg K2O).'ResuIts showed that the leaf clipping treatments had significant effect on growth and yield parameters. Removal of empty leaves resulted in the highest plant height, dry matters from leaf. stem, root and infioreseenees with yield and all the yield attributes as well1.flie fertilizer doses also affected the studied parameter significantly. The highest values on most of the growth and yield parameters were obtained with 20 kg N 4- 40 kg P205 kg K 20Tha In case of interaction of treatments, removal of empty leaves coupled with 20 kg N + 40 kg P205 ± 30 kg K2 0 (ha) showed significantly highest values on stem dry weight (10.69 plant), root dry weight (2.49 g/plant), stover weight (2.10 g/plant), pod length (12.98 cm), number of seeds/pod (12.31), 1000 seed weight (40.67 g).(grain yield (1.12 tiha) and harvest index (34.78 %) The higher yield was attributed to the absence of leaves having no infloresc-enee on their axils and also to the balanced fertilization.
