EFFECT OF SOWING DATE AND FERTILIZER ON DRY MATTER, GRAIN NUTRITION LEVEL AND YIELD OF FABA BEAN ( Viciafaba cv. Kalimotor)

Abstract

An experiment was conducted at the Agronomy field, Sher-e-Bangla Agricultural University. Dhaka to evaluate the effect of sowing date and fertilizer on the dry matter, grain nutrition level and yields of faha bean (V/cia ft-thu L.) cv. Kalimotor during the period from October 2006 to March 2007. The trial comprised with three sowing dates (20 October, 15 November and 10 December) and thur fertilizer treatments (6 kg N +- 20 kg P205 ~- 20 kg K20 + 15 kg S hi'; 12 kg N + 40kgP205 - 40kgK70+ 30kgSha1 ; 18kgN+60kgP205 +60kgK20+45 kg S hi 1 and 24 kg N + 80 kg P205 + 80 kg K20 + 60 kg S ha 1 ) which were tested in a RCBD design with three replications. Fertilizers were applied during linal land preparation. All data were recorded at harvest. Results showed that the highest values were attained with 15 November. There was a severe reduction in yield due to delay of sowing. The highest value of pods per plant (53.80), filled pods per plant (28.12). 1000-seeds weight (92.1 3g) and grain weight per plant (8.946g) were obtained with 18kg N + 60 kg P205 + 60kg 1(20 + 45 kg S hi'. The interaction effect of date of sowing and fertilizer levels was also significant. Seed yield (1.454 tlha) was the highest in 15 November sowing fertilized with 18 kg N 60 kg P205 + 60 kg 1(20 45 kg S ha* Sowing dates and fertilizers also contributed on grain nutritional level. However, the effects were a hit inconsistent.
