Abstract

[MANURE APPLICATION AS A SOIL AMENDMENT TO PROMOTE GROWTH AND YIELD OF MELON (Cucumis melo L.) IN ULTISOL]. The application of manure may overcome soil fertility problems in Ultisol triggered by low pH, high P retention, high content of Al and Fe, and low CEC. The objective of this study was to determine the optimum dose of different manures applied to promote the best growth and yield of melon. The study was conducted from February to May 2019 at the Experimental Plot of the Faculty of Agriculture, University of Bengkulu. Three different manures (chicken, cow, and goat manure) were applied at 5, 10, 15, and 20 tons/ha. These treatments were arranged in Completely Randomized Design with three replications. The results show that the enhancement in chlorophyll content (SPAD index) was highest in plots solely applied with 20 tons ha-1 manure, whereas application of manure even at 20 tons/ha had no effects on melon yield and its components. Manure types solely promoted plant height, maturity date, fruit diameter, and soluble solid content (Brix). Melon growth and yield were not affected by combined application of manure type and dose. These indicate that application of manure types irrespective of the amount applied failed to solve fertility problems in Ultisol where melon was grown.

Abstract

Soybeans can be cultivated in Entisol. However, soybean cultivation on Entisol land has problems, including low soil fertility. Providing compost and NPK is an alternative to overcome this. The research objective was to determine the best type of compost and NPK fertilizer dosage for soybean growth and yield in entisol. The research has carried out in the Entisol Bengkulu field from August to November 2020. The research design used a Complete Randomized Block Design (CRBD) with 2 factors including: the type of compost organic fertilizer consisting of: P1 = Widelia trilobata, P2 = Tithonia diversivolia, P3 = oil palm empty bunches, and P4 = Eichhornia crassipes and the NPK fertilizer dosage consisting of: N0 = 0 kg ha-1, N1 = 150 kg ha-1, N2 = 300 kg ha-1, N3 = 450 kg ha-1. Observation variables include plant growth and yield and supporting observations which include the results of initial soil analysis and climate data during the study. The results showed that NPK dosing had a significant effect on the variables of plant height, number of leaves, number of branches, root wet weight per plant, and dry weight per plant. However, the application of compost did not significantly affect all variables. Meanwhile, there was no interaction between the application of compost types and NPK dose on the growth and yield of soybean in entisols. The application of compost types and NPK fertilizer doses up to 450 kg ha-1 has not improved the growth and yield of soybeans in entisol fields.
