Abstract

The use of natural hormones of young sweet corn extract, coconut water extract, and banana stem extract and application of cow biourine has been introduced as an innovation to reduce the use of chemical fertilizers to increase the productivity of shallot. This study aims to compare the growth and yield of shallot with chemical fertilizer treatment and that of shallot treated with a combination of the natural hormone and cow urine. The study was conducted from October 2019 to January 2020 in Temon Wetan, Temon, Kulon Progo, Special Region of Yogyakarta using a Complete Randomized Block Design, which consists of two factors and one control (chemical fertilizer). The first factor is a natural hormone: young sweet corn extract, banana stem extract, and coconut water. The second factor is the concentration of cow urine: 30%, 40%, and 50%. Data were subjected to an analysis of variance followed by Duncan’s Multiple Range Test and Orthogonal Contrast at 5% It was revealed that the control group with combined treatments was not significantly different from the growth and yield of shallot of the group with chemical fertilizers. Types of treatments with natural hormone and cow urine concentrations provided the same growth and yield as that of chemical fertilizer.

Abstract

Intercropping is an attempt from agriculture’s intensification program which purposes to obtain optimum yield and maintain soil’s fertility. This research aims to know whether intercropping systems have better crops and higher yields than monoculture systems. This research was conduct on May-August 2020 at Trengguno Kidul, Sidorejo, Ponjong, Gunung Kidul. The design of the experiment was arranged in a randomized block design (RBD) one factor and three blocks. One factor namely ST 1: soybean monoculture Dega variety, ST2: maize monoculture Dega 1 variety, ST 3: Maize monoculture Srikandi Ungu variety, ST 4: Intercropping system of soybean Dega 1variety with maize Pulut Uti 1 variety, ST 5: Intercropping system of soybean Dega 1 variety and maize Nasa 29 variety, ST 6: Intercropping system of soybean Dega 1 variety with maize Pulut Uri 1 variety, ST 7: Intercropping system of soybean Dega 1 variety and maize Srikandi Ungu variety. Data were analyzed statistically using SAS (Statistical Analysis System) ANOVA 5% and further tested with the Duncan test at a significant level of 5%. The results show soybean on monoculture system has better growth and yield than intercropping while on maize of Pulut Uri and Nasa 29 plant intercropping system has the same growth and yield than monoculture. Combination intercropping of maize variety namely Srikandi Ungu and Soybean variety namely Dega proved better growth and yield.
