Abstract

This research was conducted to determine the most effective concentration of young coconut water to increase the growth of land kangkung. This study used a regression analysis design, with 15 coconut water concentration treatments, namely: 0%; 7.14%, 14.28 %, 21.42 %, 28.56 %, 35.70 %, 42.84 %, 48.98 %, 57.12 %, 64.26 %, 71.40%, 78.54%, 85.68%, 92.82%, and 99.96%. The variables observed in this study included plant height, number of leaves, leaf area, fresh weight, and dry weight. The data were analyzed using linear regression to see the effect of coconut water concentration on the growth of land kangkung plants from 15 treatments. The results of the study found that the application of coconut water at various concentrations had a significant but negative effect on plant height at 2 and 6 week, number of leaves at 2 week, leaf area at 2 week, as well as wet weight and dry weight of plants at age 6 week.

Abstract

Analysis of the growth of the Shoot Root Ratio, Stem Leaf Ratio and Leaf Weight Ratio on pagoda mustard plants are expected to provide an accurate picture of growth and yields. The aim of the study was to determine and analyze the growth of the shoot-root ratio, stem leaf ratio and leaf weight ratio of pagoda mustard greens (Brassica narinosa L.) due to the administration of liquid organic fertilizer Kascing, Papua Nutrient and MA-11. This research is held at the screen house of the Department of Soil Science, Faculty of Agriculture, University of Papua for 2 months. The tools and materials used include: machetes, hoes, polybag shovels, digital scales, 30 cm ruler, stationery, trays seedling, notebook, medication label, sprayer, hand spray, 10 ml liquid measuring tube, oven, f1 pagoda mustard seed, Kascing, Papua Nutrient, MA-11, granulated sugar, vegetable pesticide nem oil, soil media, compost, manure goats and cows. There is a significant effect due to the application of Liquid Organic Fertilizer on the Root Root Ratio, Stem Leaf Ratio and Leaf Weight Ratio. Analysis of variance and further tests showed significantly different results between the control treatment and other treatments (P1, P2, and P3). The results of the 5% BNJ test were carried out by comparing the average difference between each treatment, both P0, P1, P2 and P3 with a critical value of 3.2. Treatment of P1 Liquid Organic Fertilizer vermicompost can be said to have the most significant effect on plant growth variables because it shows the ratio of absolute average prices is greater than the critical value.
