Abstract

This study aims to evaluate how green manure applied with Chromolaena odorata and Gliricidia sepium leaves, along with NPK compound fertilizer (phonska), affects the growth and yield of sweet corn (Zea mays saccharata L.). Conducted in Telaga Kodok, Central Maluku, from September to November 2022, the experiment utilized factorial design with varying doses of green manure (0, 10, and 20 tons per hectare) and phonska fertilizer (0%, 50%, and 100% of the recommended dose). Observed parameters included plant height, leaf count, leaf area, leaf area index, cob length, cob weight with husk, cob weight without husk, and cob diameter. The results of the ANOVA analysis indicate that both factors and their interaction significantly influence sweet corn's growth and yield parameters. It is recommended to apply 20 tons of green manure per hectare and 100% phonska dose to achieve optimal results, considering parameters such as plant height, leaf count, leaf area, cob length, cob weight with and without husk, and cob diameter. By enhancing sweet corn productivity, supporting food security, and promoting sustainable agricultural sector growth, this research significantly contributes to optimizing the use of organic and inorganic fertilizers.

Abstract

In mustard cultivtion, the right combination of the concentration of liquid organic fertilizer given through the leaves and the frequency of application are factors that can optimize growth and yield. This research aimed to test the effectiveness of the concentration and frequency of NASA liquid organic fertilizer on the growth and yield of Samhong mustard (Brassica juncea L.). The research was carried out in the greenhouse of the Faculty of Agriculture, Pattimura University, Ambon. This research was conducted as an experiment using a Randomized Block Design with 2 factors. The first factor was the concentration of NASA liquid organic fertilizer which consisted of 4 levels, namely: concentration of 0 mL/L of water (without giving POC); 4 mL/L of water; 8 mL/ mL/L of water; and 12 mL/L of water. The second factor was the frequency of fertilizer application which consists of 3 levels, namely 6 times, 3 times and 2 times of application. There were 12 treatment combinations, with 3 replications, so there were 36 experimental units. The research results showed that the concentration of NASA liquid organic fertilizer had a very significant effect on plant height, number of leaves, leaf area, plant fresh weight, plant dry weight and root dry weight. A concentration of 8 mL/L of water was the best concentration for plant fresh weight, namely 323.89 g. For the treatment of frequency of application, there was a very significant effect on the number of leaves, leaf area, plant fresh weight, plant dry weight and root dry weight, with a frequency of 3 applications being the best frequency for the growth and yield of Samhong mustard greens. The interaction between NASA liquid organic fertilizer concentration and application frequency did not significantly effect all observed variables.
