PERFORMANCE OF LENTIL VARIETIES AS INFLUENCED BY IRRIGATION LEVELS

Abstract

The present study was conducted at the research field of the Department of Agronomy, Sher-e-Bangla Agricultural University, Dhaka during the period from November, 2010 to February, 2011 to evaluate performance of lentil varieties as influenced by irrigation levels. The treatment variables were three varieties (V : BARI mosur 4, V 2 : BARI mosur 5 and V : BARI mosur 6) and four irrigation levels (I 0 : no irrigation, I v : irrigation at 25 DAS, I 3 f : irrigation at 50 DAS and I : irrigatation at both 25 and 50 DAS). The experiment was laid-out in a randomized complete block design (RCBD) (factional) with three replications. Results of the study were recorded on plant height, branches plant -1 , leaves plant -1 , pods plant , plant dry weight, 1000-seed weight, seed yield, stover yield, biological yield and harvest index and were found significantly variable with irrigation levels. Individually, BARI mosur 6 and irrigation at both 25 and 50 DAS, showed the best performance on growth and yield of lentil. Combined effect also showed significant effect on all parameters of the study. BARI mosur 6 along with irrigation at both vegetative and productive stage produced the highest 1000-seed weight (24.33 g), seed yield (1967.17 kg ha -1 ) and biological yield (4467.13 kg ha -1 ). From the results it is suggested that BARI mosur 6 with irrigation at both vegetative and reproductive stages may give optimum yield. -1 vf , seeds pod 1 -1
