INFLUENCE OF PLANTING METHOD AND LEAF CLIPPING ON THE YIELD PERFORMANCE OF WHITE MAIZE

Abstract

An experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University, Dhaka-1207 during January 2018 to June 2018 to evaluate the influence of planting method and leaf clipping on the yield performance of white maize. The experiment was laid out in a split plot design with three replications. The experiment comprised of two factors. Factor A: Planting method - 2 types [P 1 ii

= Sowing, P 2 = Transplanting] and Factor B: Leaf clipping - 4 levels [C 1 = no leaf clipping, C 2 = all leaf clipping, C 3 = clipping of four leaves above cob, C 4 = clipping of four leaves below cob]. White Maize Yungnuo 3000 was used for the experiment. Significant variation was observed on growth, yield and yield contributing parameters. In the case of planting method, the highest plant height (85.43, 163.56 and 212.34 cm, respectively) at different days after planting, leaf length (39.87 cm), cob length (17.63 cm), cob breadth (12.45 cm), number of cob bearing node (7.67), number of row cob -1 (13.67), number of grain row -1 (26.61), grain yield (7.46 t ha -1 ), 100 seed weight (21.58 g), oven dried shell weight (15.72 g) and oven dried chaff weight (7.29 g) were recorded in P 1 treatment and those of the lowest from P 2 . In the case of leaf clipping, the highest plant height (89.31, 168.32 and 217.21 cm, respectively) at different days after planting, leaf length (41.87 cm), cob length (19.77 cm), cob breadth (18.42 cm), number of cob bearing node (9.33), number of row cob -1 (14.67), number of grain row (34.65), grain yield (8.69 t ha -1 ), 100 seed weight (28.47 g), oven dried shell weight (17.87 g) and oven dried chaff weight (10.88 g) were recorded from C 1 treatment

and those of the lowest from C 2 . In the case of interaction, the highest plant height (91.38, 172.34 and 219.36 cm, respectively) at different days after planting, leaf length (42.19 cm), leaf breadth (6.08 cm), cob length (20.57 cm), cob breadth (18.79 cm), number of cob bearing node (10.67), number of row cob -1 (16.33), number of grain row -1 (36.89), grain yield (8.70 t ha -1 ), 100 seed weight (29.45 g), oven dried shell weight (18.11 g) and oven dried chaff weight (11.05 g) were recorded from P 1

C 1 treatment

and those of the lowest from P 2 .
