Abstract

The goal of this research was to determine the growth response and yield of corn plants (Zea mays L.) towards the application of chitosan organic fertilizer and nitrogen fertilizer. This research used randomized block design which consists of two factors. The first factor was the concentration of chitosan organic fertilizer whith four levels: 0 ppm/ plant, 10 ppm/ plant, 20 ppm/ plant, and 30 ppm/ plant. The second factor was the dose of nitrogen fertilizer with four levels 0 g/plant, 5 g/plant, 10 g/plant and 15 g/plant. There was 16 combinations of treatments. Each treatments was replicated three times to obtain 48 experimental units. Parameters observed were number of cobs per plant, number of seeds per plant and weight 100 seeds. The results of this research showed that application of chitosan fertilizer does not affect the yield of corn plants. Chitosan fertilization with a concentration of 10 ppm tends to show higher yields on the parameters of the number of cobs (2.25 cobs) and weight of 100 seeds (35.00 g). The application of nitrogen fertilizer affects the yield of corn plants. Nitrogen fertilization with a dose of 15 g/plant increased the number of cobs (2.83 cobs) and the number of seeds per plant (647.75 seeds) compared to the control treatment. There is no interaction between chitosan fertilizer and nitrogen fertilizer on corn yields.

Abstract

The application of Moringa leaf POC is one of the best materials because it contains iron, sulfur and phosphorus which function for plant growth. Another alternative to improve pakcoy plant production is by adjusting the composition of the right planting media, for example by adding organic compost or husk charcoal. Husk charcoal is one of the planting media that functions as a soil improver and can improve soil properties. The purpose of this study was to determine the effect of several concentrations of moringa liquid organic fertilizer and the combination of planting media on the growth and yield of pakcoy (Brassica rapa L.). Data collection and processing methods using factorial group randomized design consisting of two factors. Observation data were analyzed with variance analysis (F test) at the 5% level. If there is a significantly different effect, it is continued with Duncan's Multile Range Test (DMRT) at the 0,05 level. There is an interaction between the concentration of moringa leaf POC and the combination of planting media on the parameters of plant height at 1 MST.”
