Abstract/ Executive Summary:

An experiment was conducted with four selected lines of lentil viz. ML-30, ML-52, ML-563, ML-596 and a popular check L-5 at BINA, Mymensingh during November 1992 to February 1993. The experiment was laid out in completely randomized design with three replications. Plant height, total dry matter and yield of lentil genotypes were decreased significantly at 20%FC compared to other threatments. Thre was no signifacant difference between 60 and 40% FC in plant height, total dry matter and pods per plant. The plants at 40% FC showed better translocation ability which in turn produced significanly higher yield than the plants at 60% FC. The lines ML-52 and ML-ML-563 showed better better yield at 40 and 20% FC. Due to lower traslocation ability, ML-596 did not produce substantial yield at any moisture level inspite of its highest biomass production.

Keywords: Water stress, Total dry matter, Yield, Yield attributes, Lentil

Location: BINA, Mymensingh, Bangladesh

Start Date: 00-11-1992

End Date: 00-02-1993

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

To assess the effect of water stress on lentil lines and to find out stress tolerant line

Methodology:

A pot experiment was conducted with four selected lines of lentil viz., ML-30, ML-52, ML-563, ML-596 along with a check variety L-5 at BINA during November 1992 to February 1993. Each pot contained 4 kg BINA farm soil. Three soil moisture regimes viz., 60, 40 and 20% field capacity was maintained through weighing adjustment, 2 to 3 times watering per week. The experiment was laid out in completely randomized design with three replications. Data on plant height, total dry matter and yield per plant were recorded at maturity. Data were analyzed statistically and Least Significant Difference (LSD) was used to compare the means.
