EFFECT OF ALTERNATE FURROW IRRIGATION ON WHITE MAIZE VARIETIES

Abstract

A field experiment was accomplished in the Agronomy Field of Sher-e-Bangla Agricultural University, Dhaka during the period from November, 2017 to April, 2018 to study the effect of alternate furrow irrigation on maize varieties. Maize varieties viz. V 1 (PSC - 121), V 2 (Yungnuo-3000), V 3 (BHM-12), V 4 (BHM-13) and Irrigation application: I (conventional irrigation), IA (Alternate furrow irrigation) were used in this experiment arranged in Randomized Complete Blocked Design (RCBD) with three replications. Data on different growth and yield attributes were taken in which all the treatment showed significant variations. Among variety, tallest plant height (234.7 cm), cob breadth (15.9 cm), grain yield/ cob (106.8 g), grain yield/ hectare (8.9 t), chaff weight/cob (11.6 g), shell weight/cob (25.3 g) were found from V 1 (PSC - 121) whereas minimum in variety V 3 (BHM-12) and for irrigation application, maximum cob bearing node (9.07), cob grain number (359.5), cob length (15.5 cm), grain yield/hectare (8.1 t) found in conventional irrigation application. Maximum yield per hectare (10.05 t) were found in V 1 I and minimum (4.85 t) in V 3 IA. In view of overall performances, variety V 1 with conventional irrigation application has potentiality for maize production.
