RESPONSE OF MUNGREAN VARIETIES UNDER DIFFERENT SPACING

Abstract

An experiment was conducted at the Agronomy field, Sher-e-J3angla Agricultural university. Dhaka, during August to October, 2008 to study the response of mungbcan varieties under different spacing management. Four mungbean varieties; (i) V 1 = BARI mung-3, (ii) V 2 = BAR! mung-4, (iii) V 3 = BAR1 mung-5 and (iv) V 4 = BAR! mung-6 with four plant spacing;i j S, =30 cmx 5cm, (ii) S 1 =30 cmx 10 cm, (iii) S 3 =40 cmx Scm and (iv) S 4 =40cm their combination were used under the present studY)The experiment was laid out in a Randomized Complete Block Design (RCBD) (factorial) with three replications, tile results showed that growth, yield and yield attrtbutes of mungbean significantly responed to the different varieties, spacings and their combined effectsJ(\t harvest, variety BAR! mung-6 gave maximum branches plant" (1.83), above ground dry matter planf' (11230 g), pod length (9.29cm), pods plant -'(] 3.92), seeds pod ' (1397), 1000 seed weight (51.03 g). seed yield (1483 kg hi'), stover yield (2432.48 kg ha 4 ). harvest index (37.83%) and light intensity (47.83 lux). pacing S4 (40 cm , :10 cm) gave maximum branches plant" (1.96), above ground dry matter plant" (116.20 g), pod length (9.71 cm), pods plant"(15.36). seeds pod" (12.40), 1000 seed weight (52.40 g), light intensity (51.42 lux) but failed to gave maximum seed yield due to less plant population per unit area. where as S1 ( 30 cmx 10 cm) gave maximum seed yield (3520 kg ha") and harvest index (38.17%) with higher plant establishment. The combination effect of BAR! mung-6 along with spacing 30 cmx 10 cm showed maximum grain yield (1645 kg ha") with higher value of harvest index (40.16%).
