Abstract/ Executive Summary:

A field trial was conducted at the Hill Agricultural Research Station, Kagrachari during the period from November 2006 to March 2007 to find out the influence of hilly environment on vegetative growth and reproductive development in lentil varieties. Four varieties of lentil were tested in a RCB design with three replications. The hilly environment significantly affects the growth, development and yield of lentil varieties. BARI masur 4 showed better growth and development, produced highest total dry matter, bear maximum branching and finally contributed highest grain yield under hilly environment. Although the experiment was late sown and infested by stem phylum blight disease due to heavy rain during flowering and pod development stage that causes low yield of lentil. Therefore the experiment should be repeated in the next season.

Keywords: Hilly envirornment, Growth, Reproductive development, Lentil varieties

Location: ARS, Khagrachari

Start Date: 00-11-2006

End Date: 00-03-2007

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

To find out the influence of hilly environment on growth, flowering and pod setting and yield of lentil.

Methodology:

The study was conducted at the Hill Agricultural Research station, Khagrachari after T.aman rice harvest during the period from November 2006 to March 2007. The trial was laid out in a RCB design with three replications. Four BARI released lentil varieties viz. BARI masur 1, BARI masur 2, BARI masur 3 and BARI masur 4 were included in the experiment. Seeds were sown on 30 November 2006 @ 25 kg/ha in solid line with 30 cm row spacing. The unit plot size was 5m x 4m. Fertilizers @ 40-60-20-10-5 kg/ha N, P₂O₅, K₂O, S, Zn and B respectively were applied. All fertilizers were applied as basal before sowing. Other intercultural operations such as weeding, thinning, irrigation, pesticide application were done as and when necessary. The data were collected on days to flowering, days to maturity, grain growth period, plant population at harvest, total dry matter production, plant height, branches per plant, pod per plant, seed per pod, 1000-seed weight and grain yield. Collected data were statistically analyzed following "MSTAT" program. The differences between the means were compared using the least significant difference (LSD) test.

Achievement/Findings:

The hilly environment significantly affects the growth, development and yield of lentil varieties. BARI masur 4 showed better growth and development, produced highest total dry matter, bear maximum branching and finally contributed highest grain yield under hilly environment. Although the experiment was late sown and infested by stem phylum blight disease due to heavy rain during flowering and pod development stage that causes low yield of lentil.
