The Effects of Bat Guano Manure as Alternative Organic Fertilizer in Rice Production in Delta State, Nigeria

Field experiment was conducted in Delta State University, Asaba Campus during 2018 and 2019 raining seasons to evaluate the influence of different rates of bat guano manure as organic fertilizer in rice production. The bat guano was applied at 0 (control), 2.5, 5.0 and 10.0 t/ha. The experiment was laid out in a randomized complete block design replicated four times for the two years. On weekly bases, plant height and plant leaf area were measured while number of tillers, dry matter and grain yield were measured at harvest. Data obtained were subjected to analysis of variance and means were separated with Duncan Multiple Range Test at 5% level of probability. Results showed that bat guano manure significantly influence the growth and yield of rice. The growth and yield parameter of rice increases with all the bat guano rates but 10 t/ha rate recorded the highest estimates in both years. This indicates that the bat guano manure can be successfully used as alternative organic fertilizer in production of rice in the study area.
