Abstract:

An experiment was conducted at Agricultural Research Station Buner, Khyber Pakhtunkhwa Pakistan during 2014 to study the effect of plowing time i.e. in dark (at night) and in sunlight (at day) and sowing time i.e. immediate after plowing and 12 hours later, on various maize hybrids. Two fields were selected for day and night plowing. Night plowing was done at 10.00 p.m. while day plowing at 8.00 a.m. Furthermore, half of the plowed field in each case was sown immediately after plowing and the rest, 12 hours later. Three hybrids of maize i.e. Monsanto-2021, Rafhan-3313 and Rafhan-3304 were sown in each field under two factorial randomized complete block design (RCBD) with four replications. Generally a significant interaction among plowing and sowing time was observed for the recorded parameters. Fewer weeds infestation (90 gm-2) was observed for the field plowed at night. Day time plowing increased weeds infestation (247 gm-2); however, heavier 1000 grains (307 g), greater shelling percentage (78.8%), and highest grain yield (8242 kg ha-1), were recorded for the field plowed at night. There were also significant differences among various hybrids, where Monsanto-2021 produced better results. Plowing the field at night proved superior in term of weeds reduction, grain yield and crop growth rate as compared to the field plowed at usual daytime. Night plowing is recommended to decrease weeds emergence and to increase grains and stovers yield. Sowing can be done immediately after night plowing or on subsequent day of plowing. Hybrids particularly, Monsanto-2021 is recommended for maximum yield and yield components.
