The Influence of Guano Organic Fertilizer in Sustainable Agricultural Systems on Growth and Results of Sweet Corn Plants (Zea mays saccharata L)

The availability of renewable natural resources needs to be maintained as biological and sustainable survival, the use of guano or bat droppings is one of them, bat droppings can be used as an ingredient for making organic fertilizers for plant growth and yields, so this study aims to determine the effect of guano organic fertilizer dosage. on growth and yield of sweet corn (Zea mays saccharata L). This research was conducted on agricultural land using beds measuring 300 cm x 200 cm x 20 cm. using 4 (four) treatments and 4 (four) replications. Fertilizer dosage treatments were: g0 = without Guano organic fertilizer, g1` = 3 tons of guano organic fertilizer. ha-1 or 1.8 kg. plot-1, g2 = 5 tons of guano organic fertilizer. ha-1 or 3 kg. plot-1, g3 = 7 tons of guano organic fertilizer. ha-1 or equivalent to 4.2 kg. Plot-1. Observation parameters consisted of plant height (cm), number of leaves (strands), stem diameter (cm), fruit diameter (cm), fruit length (cm), fruit weight per plot (kg). The results showed that the use of various doses of organic fertilizer guano g3 = 7 tonnes of organic fertilizer guano ha -1 or equivalent to 4.2 kg/plot had a significant (P < 0.05) effect on plant height, number of leaves of sweet corn plants, and a very significant effect. significantly (P < 0.01) on cob diameter, stem diameter, and fruit weight per plot. The use of guano or bat droppings as organic fertilizer at increasing doses up to 7 tons.ha-1 gave the best results for all research parameters. Bat populations as producers of guano or organic fertilizers need to be maintained and preserved in a sustainable agricultural system.
