PERFORMANE OF BUSH BEAN (BAR! bush bean-i) AS AFFECTED BY INTEGRATED NUTRIENT MANAGEMENT

Abstract

An experiment xNas conducted at the expertniental IlcIc. Demrtnient of Soil Science. Slier-cBangla Agricultural I .niversit -

Dhaka during mid-November. 2011 to mid-March. 2012 to \aIuate the suitability of I3ARI bush bean-I cultivation \\ alt inorganic N lértilizer and organic co' dune application. Ihe experiment was laid out löllo ing Randomized Complete i3iock Design (RCI3D) with three replications. The treatments of the experiment involved. .1_I (90 kg N from urea): 12 (80 kg N from urea tO kg N supplemented by cowdung): 1: (70 ke N from urea 20 kg N supplemented by cow dung): I 00 kg N from urea- 30 kg N from urea): 1 (50 kg N from urea 40 kg N supplemented Ii) codung): l (40 kg N from tirea- 50 kg N supplemented by cowdun(l): T 7 (30 kg N front urea- 60 kg N supplemented by cowdung): T ( 90kg N supplemented by eowduug) and 19 (Control) treatment. And the variety which was involved in the experiment. V 1 = I3ARI bush bean-I. A signilicani variation as observed among the treatment in respect of different parameters of IIARI bush bean-I. The tallest plant (43.67 eni) was recorded from i. while the shortest plant (33.67 cm) from I, (control) treatment. The maximum number of branches per plant (7.667) was obtained from Is (90 kg N supplemented by cowdung). The maximum number of' flowers/plant (27.67) was observed from Ti(50 kg N from urea 40 kg N supplemented by cowdun(). the minimum number of I1owersplant (12.33) was observed from T 9 (control) treatment. The maximum number of pods per plant (25.0) was obtained from Ti treatment And the niinmtunt number of pods per plant (1 I .3) was obtained from 1., (control) treatment The highest length of pods in each harvest (1 2.89 cm) was recorded from T (50 kg N from urea -'40 kg N supplemented by cowdung). While the lowest weight (II). 11 cm) front 1 (control) treatment. An optimum amount m nitrogen tbr the whole growth period is necessary to produce niaximuin yield of good quality bush bean. The highest weight of 100 pods (4.71kg) at each harvesting was recorded from 1 4 (50 kg N from urea 140 kg N supplemented hs co'duugL the lowest weight (199 k) from 1I) ( control) treatment Maximum green pod yield of bttsh bean (13.44 \rI]ile tlha) was recorded from R (50 kg N from urea -40 kg N supplemented by cow dung).
