It appears from the results that the short duration lines flower as early as 35-44 days but mature within 90-95 days. The lines though complete podding early but don’t mature early because of low temperature up to mid February. Not only that the short duration lines have very less no. of plants/m2, less braches/ plant, very few pods/plant and ultimately produced very low yields compared to the released varieties. BARI Masur-5 produced the highest grain yield (2142 kg/ha) followed by BARIMasur-3 (1643 Kg/ha) and the lowest yield (318.3 kg/ha) was recorded in 22-15 which is statistically similar to 22-95, 22-215, 22-146. Among short duration lines, 21-109 produced slightly higher yield of 1067 kg/ha. Earlier, this genotype also found short duration with promising yield. Considering the maturity, yield and other characters it may be concluded that short duration lentil can’t be fitted in between Aman and Boro rice as a relay crop but it can be fitted in between T.aman and T.Aus rice.

Variety and Species
To find out the short duration variety for better establishment of lentil relay cropping for the development of T.aman/+lentil relay –Boro rice cropping pattern.
A field experiment of lentil relay cropping was conducted at PRC, Ishurdi, Pabna during rabi season of 2012-13 under rainfed condition in transplanted aman rice field. There were 8 lentil genotypes/variety viz. 21-109, 22-15, 22-70, 22-215, 22-95, 22-146, BARI lentil-3 and BARI lentil-5. It was laid out into RCB design with three replications. The unit plot size was 4m x 5m. The sowing date was 11 November 2012. In the experimental plots, fertilizers @ 40-20 kg/ha of P205-K20 were applied in the existing rice field before two days of seed sown. Different genotypes seeds of lentil were sown in the existing rice field as per design. The seed rate of lentil was 50 kg/ha. After 15 days of lentil germinations rice plants were harvested retaining 25cm rice straw height. Intercultural operations were done as and when necessary. Urea was applied @ 20 kg/ha of N at 20 DAE in the experimental plot. Lentil was harvested on different dates as per maturity of lentil genotype/variety. Data on yield contributing characters were recorded from 10 randomly selected plants from each plot and grain yield (kg/ha) was recorded from whole plot at harvest. The recorded data were statistically analysised and mean values were adjudged by Duncan’s Multiple Range Test.
