Effect of irrigation and mulch on maize yield (Zea mays) in southern areas of Bangladesh
Journal Title: Journal of Agricultural and Crop Research - Year 2018, Vol 6, Issue 2
Abstract
This study was conducted at the farmer's field of Babugong Upazilla, Barisal to determine the effect of irrigation sequences and straw mulch on the yield of maize. The experiment consisted of two factors: irrigation and mulch. The irrigation treatments in the main plot as I1 Farmer practice, I2 One irrigation at 4 leaf stage, I3: Two irrigations each at 4 leaf stage and 8-10 leaf stage, and I4: Three irrigations each at 4 leaf stages, 8-10 leaf stage and tasseling stage. The subplot treatments as M1: No mulch, M2: Mulch with 1 cm thickness, M3: Mulch with 2 cm thickness, and M4: Mulch with 3 cm thickness. The variety of test crop was BARI hybrid Maize-9. I4 (Three irrigations each at 4 leaf stage, 8-10 leaf stage and tasseling stage) produced the highest plant height (274.3 cm) stating that plant height is directly proportional to water availability but the quantity must not exceed the optimal quantity. From two year observations, I3M3 (Two irrigations each at 4 leaf stage and 8-10 leaf stage with 2 cm thick mulch) produced the highest number of grain per cob and 100-grain weight. The highest grain yield and biological yield were also obtained from I3M3 over two years of observations. Among all treatments, I3M3 (Two irrigations each at 4 leaf stage and 8-10 leaf stage with 2 cm thick mulch) produced the highest BCR (1.70).
