    EFFECT OF NITROGEN AND IRRIGATION MANAGEMENTS ON THE YIELD ATTRIBUTES AND YIELD OF MUNGBEAN
    (DEPARTMENT OF AGRONOMY, 2006) MD. ASADUZZA MAN
    An experiment Was conducted at the experiment field of the Department of Agronomy. Sher-e-Bangla Agricultural University: I)haka to evaluate the ciThet of nitrogen and irrigation managements on the yield attributes and yields of mungbean (V/gnu rat/ia/a lj.) cv.BARI mung-5 during the period from March 2006 to May 2006. The trial comprised often treatments such as T1 control. 12 20 kg N ha 4 as basal. 13=20 kg N ha4 as basal with one irrigation at first flowering stage, 1 4 =30 kg N ha" as basal. T5 30 kg N hzi' as basal with one irrigation at first flowering stage. •1'--40 kg N ha" as basal. 'F 40 kg N as basal with one irrigation at first flowering stage. lhasal 10 kg N ha' and 10 kg N h&' as split with one irrigation at first flowering stage, l 9=bacal 15 kg N ha'' and 15 kg N ha'' as split with one irrigation at first flowering stage and 1, 0—basal 20 kg N h& and 20 kg N ha'' as split with one irrigation at first flowering stage. Irrespective of treatment di rierenees the mungbcan plant as a pulse crop showed a lag phase in early growth stage (up to 40 DAS) while increase of growth parameters like number of leaves, leaf dry weight and steam dry weight per plant very slow. Thus, initiation of flowers (35 DAS) caused low dry matter production. Application of 30 kg N ha'' as basal with one irrigation at first flowering stage (35 DAS) improved the growth parameters significantly. This greater dry matter eventually supported the plant to produce more number of branches and pods per plant. which resulted with maximum seed yield per plant (5.53 g) or per hectare (1.65 ton). A Iiinctional positive relationship was observed among number of branches per plant. pods per plant. seeds per pod and seed yield.
