Application of various source animal manure and dosage on the growth and yield Phaseolus vulgaris L.

Abstract

Animal dung in Indonesia has many types; each type of manure gives different plant growth response. This study aims to determine the type of manure and its adequate dosage to increase the growth of bean plants. The research has been carried out in the experimental field of Universitas Padjadjaran, Jatinangor, Sumedang-West Java with altitude 753 m above sea level (asl). The study used a factorial randomized block design. The first factor is the type of manure (k1 = cow manure, k2 = sheep manure, k3 = chicken manure, and k4 = rabbit manure) and the second factor is the dose (d1 = 10 t ha−1, d2 = 20 t ha−1, and d3 = 30 t ha−1). Each unit was repeated three times. The growth parameters observed were plant height, dry plant weight, number of pods, and pod weight per plant. The data from observations were then analyzed using analysis of variance at 5% significance level and then followed by Duncan’s test at 5% significance level. The results showed the application of chicken manure 20 t ha-1 gives better growth results than other manure, but the type of manure at various dosage levels has not been able to increase the weight of pods per plant.
