The effect of organic fertilizers on growth several varieties of soybeans

Abstract

This study aims to analyse the effect of three types of organic fertilizers on the vegetative growth several varieties of soybeans. This study used a factorial randomized block design with two treatment factors, namely organic fertilizers and varieties. The first factor is: organic fertilizer from 3 levels, namely: K1 (1.5 kg of compost), K2 (1.5 kg of goat manure), and K3 (1.5 kg of chicken manure). The second factor is: soybean plant varieties consist of 4 levels, namely: V1 (Dena 1), V2 (Devon 1), V3 (Anjasmoro) and V4 (Derap 1). The parameters observed were plant height, number of branches, number of leaves, amount of chlorophyll, leaf area, and flowering age. The results of our research is organic fertilizers have a significant effect and are able to increase the growth of soybean plants except for leaf area and flowering age. Types of varieties had a significant effect and were able to increase plant height, number of branches, leaf area, and flowering age, but had no significant effect on the parameters of the number of leaves and the amount of chlorophyll. Moreover, there isn't interaction effect between the two treatments for all parameters.

Respon Fisiologi Kedelai (Glycine max. L (Merr)) Varietas Ajasmoro Di Kecamatan Ruteng, Kabupaten Manggarai

“…Berdasarkan hasil analisis menunjukkan bahwa tanaman kedelai dibeberapa perlakuan pupuk jerami berpengaruh tidak nyata untuk meningkatkan kandungan klorofil tanaman meskipun setiap perlakuan menunjukkan penambahan jumlah klorofil (Tabel2). Berbeda dengan penelitian Rizwan et al (2021) menjelaskan bahwa pupuk organik memengaruhi pertumbuhan dan jumlah klorofil pada tanaman kedelai. Hal tersebut dapat terjadi diduga karena adanya pengaruh naungan sekitar tanaman.…”

Evaluation of growth and yield of upland rice varieties under various shading levels and organic fertilizer concentrations

“…Variety responses to fertilizer, particularly organic fertilizer, mirror plant adaptability to nutrient input from the environment. Fertilizing using organic fertilizer deemed to be better due to its ability to continue providing nutrients according to plant needs (Rizwan et al 2021;Tuhuteru et al 2021). Furthermore, raw material sources such as rice straws are abundant.…”
