EFFECT OF NUTRIENT SOURCES AND IRRIGATION FREQUENCY ON GROWTH AND YIELD OF FRENCH BEAN

Abstract

A field experiment was carried out in the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh during the period of November 2016 to March 2017 The variety BARI Jhar Sheem 1 was used as test crop. Four levels of nutrient sources viz. F 1 : 0 (Control), F 2 ii : N 60 +P 20 +K 30 , F 3 : Vermicompost (10 t ha -1 ) and F 4 : N 30 +P 10 +K 15 + Vermicompost (5 t ha -1 ) and three levels of irrigation frequency viz. I 1 = 3 days interval, I 2 = 6 days interval and I 3 = 9 days interval were used for the present study. The experiment was laid out in Randomized Complete Block Design with three replications. Different nutrient sources treatment showed significant influence on most of the parameters and the treatment. The highest yield ha -1 (12.87 t) of French bean was obtained from F 4 and the lowest (9.05 t) was obtained from F 1 .

Considering different irrigation frequency, the highest yield ha -1 (12.07 t) of French bean was observed in I 2 and the lowest (9.47 t) was obtained from I 3. In terms of combined effect of nutrient sources and irrigation frequency, all the studied parameters were influenced significantly. The highest pod yield ha -1 (15.19 t) was recorded from the treatment combination of F 4 I 2 where the lowest (8.53 t) was recorded from the treatment combination of F 1 I 3 . Therefore, Application of N 30 +P 10 +K 15 and Vermicompost (5 t ha -1 ) with Irrigation at 6 days interval was best for French bean production.
