Komparasi Pengaruh Pupuk Kandang Ayam dan Domba Terhadap Pertumbuhan Tiga Komoditas : Padi, Kedelai, dan Pakcoy

Abstract

This study aims to analyze the effect of various types of manure on the growth of rice (Oryza sativa L.), soybeans (Glycine max L.) and pakcoy (Brassica rapa L.), as well as to provide practical recommendations for the use of manure in supporting sustainable and environmentally friendly agriculture. This research was conducted at the Faculty of Agriculture of the University of North Sumatra from july 2024 to December 2024. The study employed a Non-Factorial Randomized Block Design with treatments including chicken manure 20 tons/ha, sheep manure 20 tons/ha, chicken manure 20 tons/ha + sheep manure 20 tons/ha, chicken manure 15 tons/ha + sheep manure 15 tons/ha, and chicken manure 10 tons/ha + sheep manure 10 tons/ha. The results showed that the response of rice plants to chicken manure and sheep manure had a significant effect on plant height, number of leaves, number of tillers, biomass weight, and fresh weight of the canopy, but had no significant effect on fresh root weight. The best treatment for rice plants was obtained with a combination of 20 tons/ha of chicken manure and 20 tons/ha of sheep manure. A different response was obtained for soybean plants, where the application of chicken manure and sheep manure had a significant effect on plant height and number of soybean leaves at 3-5 weeks after sowing. The combination treatment of 20 tons/ha of chicken manure and 20 tons/ha of sheep manure showed the highest yield, but did not have a significant effect on biomass weight, fresh weight of the canopy, and fresh weight of the roots. The response of pakcoy plants to the application of various doses of chicken manure and sheep manure did not have a significant effect on plant height, number of leaves, biomass weight, fresh shoot weight, or fresh root weight of pakcoy plants.
