Effect of Phosphorus and Calcium Availability as Influenced by Manure, Rock Phosphate, and Dolomite on Soybean Yield

Abstract

Soybean (Glycine max) contains nutritional components such as high protein which support health needs and improve the quality of life. However, to achieve this standard, soybean productivity needs to be increased. Manure, rock phosphate, and dolomite are potential alternatives in improving soybean production. This study aims to examine phosphorus and calcium availability as Influenced by manure, rock phosphate, and dolomite to increase soybean yield. The experiment consisted of six treatments groups with four replications using a completely randomized block design. Furthermore, the groups include T0 (Control), T1 (5 t ha− 1 manure + 2.5 t ha−1 rock phosphate), T2 (5 t ha−1 manure + 5 t ha−1 rock phosphate), T3 (5 t ha− 1 + 2.5 t ha−1 dolomite), T4 (5 t ha−1 manure + 5 t ha−1 dolomite), and T5 (5 t ha−1 manure + 5 t ha− 1 rock phosphate + 5 t ha−1 dolomite). The results showed that phosphorus and calcium availability were significantly influenced by manure, rock phosphate, dolomite, and simultaneously increase soybean yield. Also, the best number of filled pods, 100-seed weight and yield were obtained with the application of 5 t ha−1 manure + 5 t ha−1 rock phosphate + 5 t ha−1 dolomite (20 pods plot−1, 0.62 g, and 260.89 g plot−1 respectively). Therefore, based on the results, phosphorus and calcium obtained from manure, rock phosphate and dolomite potentially increase soybean yield.

The Effectiveness of Dolomite Phosphate Rock on Growth and Yield of Black Sesame (Sesamum indicum L.) in Paddy Field

“…There were no significant differences in sesame yield between plants fertilized with 0.5 and 1.0 t ha -1 DPR. The soybean yield increased when dolomite or phosphate rock was applied in a single form or in combination (Minardi et al, 2021).…”

Growth and Yield of Soybeans in Various Growing Media Composition and Inoculation of Rhizobacteria on Marginal Soils

“…Common problems in latosol soil are acid soil reactions, low organic matter content, low nutrient availability and reserves, and high Al saturation (Maas et al 2020;Ikhwani et al 2021;Wardani et al 2021;Wei et al 2021). The typical reaction of this soil will impact increasing Al content, which is toxic to plants, besides affecting P availability because P is fixed in the form of Al-P (Widawati dan Suliasih 2020;Fernandes et al 2021;Minardi et al 2021). Therefore, a necessary effort needs to be found as an alternative to improve soil fertility and optimize the management of soil organic matter (Diptaningsari dan Rivaie 2021;Thapa et al 2021).…”
