Abstract

Fertilizer is one of the main sources to increase the growth of rice plants. Provision of fertilizers in accordance with the vegetative and generative needs of rice plants will be able to increase the vegetative growth of rice plants, to see how the nutrients needed by rice plants are sufficient or not can be seen by the soil nutrient index so that fertilization effectiveness can be achieved. The purpose of this study was to provide N,P,K,Mg fertilizer doses according to the vegetative and generative needs of the plants and to see the soil reaction by looking at the nutrient index. The design of this experimental study was a factorial Completely Randomized Design (CRD) with 2 factors and 3 replications. The first factor is the complete application of Urea, SP-36, Kcl, and dolomite fertilizer consisting of: 0 g/plot; 549.574 g/plot; 824.36 g/plot; 1099.15 g/plot; 1373.94 g/plot. The second factor is the soil nutrient index consisting of: 0.9 (dose reduced by 10%); 1 (Standard nutrient index); 1.1 (Dose of fertilizer plus 10%) . The results showed that the application of fertilizer based on the nutrient index had a significant effect on the growth of plant height and the number of rice tillers. The addition of fertilizer in high doses of 1373.94 g/plot was able to produce a maximum growth of 101.73 cm/plot and the number of tillers was 55.52 stems/plot. The results of the research on the interaction between fertilizer doses and soil nutrient index combinations were best found in the P4B2 treatment on plant height and P4B1 on the number of tillers.

Abstract

This research aims to determine the effect of fertilizer dosage on the growth of land kale (Ipomoea reptansPoir). The research was carried out using a completely randomized experimental design (DEC) involving several fertilizer dose treatments, namely 0 kg/ha, 50 kg/ha, 100 kg/ha, and 150 kg/ha. Each treatment was repeated three times to ensure the accuracy of the results. The parameters observed included plant height, number of leaves, and land kale plant biomass. The results showed that fertilizer dosage had a significant effect on plant growth. A fertilizer dose of 100 kg/ha gave the best results on all growth parameters, followed by a dose of 50 kg/ha and 150 kg/ha. A fertilizer dose of 0 kg/ha shows the lowest growth. These findings indicate that optimal fertilization is very important to increase the growth yield of land kale. This research provides recommendations for efficient fertilizer doses to support maximum growth of land kale plants. Keywords: fertilizer, land kale, fertilizer doses
