EFFECT OF IRRIGATION ANID VARIETY ON GROWTH AND YIELD OF LENTIL

Abstract

A field experiment was conducted at Sher-e-Bangla Agricultural University farm, Dhaka during the period from November 2008 to February 2009 to study the effect of irrigation and variety on growth and yield of lentil. The experiment was consisted of two treatment factors; factor A: four irrigation levels (!= no irrigation, 11= irrigation at 25 DAS, 12= irrigation at 50 DAS and 13= Irrigation at both 25 and 50 DAS) and factor B: four lentil varieties ('i= BARI Masur-3.

V2= BARI Masur-4, V3 = BARI Masur-5 and V 4 = BARI Masur-6). The experiment was laid-out in split plot design with three replications assigning irrigation level in the main-plot and variety in the sub-plot Results showed that irrigation level, variety and their interaction exerted significant influence on plant height and plant dry matter at different days after sowing (DAS), on pods plani', seeds per pod', 1000-seed weight, seed yield, stover yield, biological yield and harvest index of lentil. Increasing irrigation level increased seed yield. BARI Masur-6 gave the highest seed yield followed by BARI Masur-5, BARI Masur-4 and BARI Masur-3. Irrigation at both 25 and 50 DAS in BARI Masur-6 showed the highest seed yield. In all the cases, increasing seed yield were obtained by increasing the values of the said parameters.
