EFFECT OF CULTIVAR AND ROW SPACING ON THE GROWTH AND YIELD OF LENTIL

Abstract

The experiment was carried out at farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, during the period from October 2008 to April 2009 to find out the effect of cultivar and row spacing on growth and yield of lentil. The experiment consisted of two factors, viz., Factor A: Cultivar (4 levels) - C : BARI Masur-3, C 2 : BARI Masur-4, C 3 : BARI Masur-5 and C : BARI Masur-6; Factor B: Row spacing (4 levels) - S 1 : Row spacing – 20 cm, S 2 4 : Row spacing – 25 cm, S : Row spacing – 30 cm and S : Row spacing – 35 cm. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on growth parameters of the studied crop were recorded after every 10 days starting from 30 DAS to 70 DAS and at harvest. Among the 4 cultivars, C 4 (BARI Masur-6) produced the highest height in plant, maximum number of branches plant 4 -1 and maximum dry matter plant -1 at every recording day, whereas the corresponding lowest values were obtained from the cultivar C 1 (BARI Masur-3). In row spacing S (20 cm) obtained the highest value in plant height, number of branches plant -1 1 and in dry matter accumulation while the corresponding lowest values were obtained from the row spacing S (35 cm). In respect of yield and yield contributing characters such as number of pods plant 4 -1 , pod length, grain yield and straw yield, the cultivar C (BARI Masur-6) also had the highest values which were 48.26 plant -1 1 4 3 , 3.26 cm, 2.14 t ha

and 2.81 t ha -1 , respectively, while the cultivar C (BARI Masur-3) gave the lowest values which were 40.21 plant -1 , 2.89 cm, 1.64 t ha 1 -1 and 2.17 t ha -1 , respectively. In combination effect of cultivars and spacing, the combination of C (BARI Masur-3) and row spacing S 1 1 (20 cm) performed the worst obtaining the lowest values in all growth and yield parameter while BARI Masur-6 with row spacing 20 cm obtained the highest value in plant height, BARI Masur-5 with row spacing 30 cm on number of branches plant -1 and BARI Masur-6 with row spacing 30 cm in yield and yield contributing characters. The highest grain and Stover yield obtained in the combination effect of study were 2.27 t ha corresponding lowest values were 1.36 t ha -1 -1 and 3.02 t ha and 1.69 t ha -1 -1 . , respectively while the -1
