Abstract

This research aimed to determine the effect of a combination of  organic fertilizer and synthetic fertilizer on the growth and yield of Dayak onion  plant. The research was carried out in a garden in  Berbah, Sleman Special Region of Yogyakarta, at an altitude of ± 194 m above sea level, the average rainfall is 145 mm year-1 and the temperature is between (24 -32) °C. The research is arranged in a Factorial Completely Randomized Design {(3 x 4) 3} = 36 units, each unit consists of 8 plant polybags, 4 plants as sample plants. The first factor is three levels of source  organic fertilizer: cow manure (P1), goat manure (P2) and household waste compost (P3). The second factor is four levels of dose of urea : 0 (N0), 4 (N1), 6 (N2) and 8 (N3) g polybag-1. Observations variables included components of growth and yield of Dayak onions. Analysis of variance used diversity analysis at the 5% level significant, followed by Duncan's Multiple Range Test at the 5% level significant. The result of the research showed that there was an interaction between the source of organic fertilizer and the dose of urea fertilizer on the variable components of growth and yield of Dayak onion plant. The best growth of dayak onion plant was obtained from a combination of goad manure with urea fertilizer at a dose of 6 g polybag-1, while high tuber weight was obtained from combination of compost fertilizer and urea at a dose 4 g polybag-1.

Abstract

This study aims to evaluate the agronomic response of Ciherang rice plants during the vegetative and generative phases under deficit irigation conditions, as a benchmark for cultivation in dry land. This study used a factorial Completely Randomized Design with two factors. First, the level of water efficiency consisting of three levels, namely 300 ml, 600 ml, and 900 ml; second, the ratio of cattle manure and urea fertilizer also consisting of three levels, namely 80:20, 50:50, and 20:80. The observed variables include vegetative phase parameters, such as plant height, number of tillers, and dry weight of biomass, as well as generative phase parameters, such as percentage of filled grains and weight of filled grains per clump. The results showed that there was a significant interaction between water efficiency and fertilizer ratio during the generative phase, but no similar interaction was found during the vegetative phase. Furthermore, the combination of 600 ml water treatment with a 50:50 fertilizer ratio produced the highest percentage of filled grains and weight of filled grains. These results indicate that Ciherang rice can grow well under efficient water conditions, making it potentially suitable for cultivation in dry land.
