Abstract

Field experiments were conducted at Yezin farm and Sepin research farm, Yamethin, Myanmar to study the effect of different mulching materials on percent reduction of soil moisture content and physiological traits in Yezin and Yamethin. Randomized complete block design (RCB) was used with three replications from October, 2019 to March, 2020. Rice straw mulching (T2), rice husk mulching (T3), maize stover mulching (T4), mung bean stover mulching (T5), soybean stover mulching (T6) and white plastic polyethylene mulching (T7) and no mulching (T1) were tested with NK-621, variety. At Yezin, the minimum percent reduction of soil moisture content (45.89) was obtained from T2 and (76.79, 58.07) was resulted in T7 whereas the maximum percent reduction of soil moisture contents (76.93, 89.00, 83.93) were recorded from T1 at 14 DAI (Days after irrigation). At tasseling stage, the maximum photosynthesis rates (20.45 µmol m-2s-1) and (21.59 µmol m-2s-1) were observed from T2 at Yezin and Yamethin. At two locations, the maximum stomatal conductance (158.36 mmol m-2s-1) and (204.44 mmol m-2s-1) was observed from T2 at maximum growth stage. At maximum growth stage, the maximum SPAD values (33.90) and (53.98) were obtained from T6 at Yezin and T2 at Yamethin. The maximum five ears weight (1830.6 g) was recorded from rice straw mulching whereas the minimum five ears weight (1326.0 g) was resulted from no mulching at Yamethin. According to the results, rice straw mulching resulted in the highest physiological traits of maize, and white plastic polyethylene mulching recorded the minimum percent reduction of soil moisture content at Yezin and maize stover mulching at Yamethin.

Abstract

Two field experiments were conducted during dry season (October, 2019 to March, 2020) at Yezin Agricultural University farm and Sepin research farm, Yamethin, Myanmar to investigate the effect of different mulching materials on yield and yield components of maize. No mulching and six mulching materials (rice straw mulching, rice husk mulching, maize stover mulching, mung bean stover mulching, soybean stover mulching and white plastic polyethylene mulching) were laid in a Randomized Complete Block Design (RCB) with three replications on NK-621 variety. The longest days to 50% tasseling (69.67) at Yezin and (71.67) at Yamethin were obtained in no mulching while the shortest days to 50% tasseling (62.00) at Yezin and (64.33) at Yamethin were observed from rice straw mulching at Yezin and white plastic polyethylene mulching at Yamethin. Number of kernel row-1, rows ear-1, row length, kernels ear-1, thousand grains weight were significantly different among different mulching materials at Yezin. The maximum grain yield (5.72 ton ha-1) and (10.39 ton ha-1) were observed from rice straw mulching at Yezin and Yamethin. According to the results, rice straw mulching resulted in the highest yield and yield components of maize at two locations.
