Abstract

The people in Indonesia widely know cauliflower plants. In addition to their delicious taste, they also contain a high nutritional value for various kinds of dishes, both in restaurants and families. The purpose of this study was to determine the appropriate dose of liquid organic fertilizer (LOF) in order to obtain maximum growth and production of cauliflower (Brassica olerasea var Botritis). The study was conducted at the greenhouse of the Agriculture Faculty of Kadiri University. The experimental design employed a Completely Randomized Design (CRD), which consisted of six treatments repeated four times with a level test using the 5% Least Significant Difference test. Based on the results of observations and data analysis, it was found that the LOF dose treatment had no significant effect on the parameters of the average plant height, the number of leaves, and leaf area at the age of 9 days after planting (DAP). However, there was a highly significant difference in the observations of the average plant height, number of leaves and leaf area at the age of 16, 23 and 30 DAP. The average plant height, number of leaves, and leaf area were the largest in the D3 treatment (LOF dose of 75ml/plant). The observation of root wet-weight, root dry-weight, plant wet-weight, plant dry-weight, flower wet-weight, and flower dry-weight on different LOF dose treatment showed a highly significant difference, and the highest average was in the D3 treatment (75ml/plant). For the observation of harvest index, various doses of LOF showed a highly significant difference, and the highest average was in treatment D2 (50 ml/plant). However, it was not significantly different from D4 (100 ml/plant).

Abstract

Cucumber is one of the important vegetable commodities that have high nutritional value and is alternative medicine. To increase the productivity of both plants and the land where plants are grown, organic fertilization is needed. Manure is an organic fertilizer to increase soil fertility so that plant growth increases. Giving different types of manure with different doses will result in different plant growth and development. The purpose of this study was to determine the effect of the interaction between the type and dose of manure treatment on the growth and production of cucumbers. This study is a factorial experiment with two factors, which were arranged according to a completely randomized design (CRD) and repeated 3 (three) times. The first factor is the type of manure consisting of 3 levels, namely: chicken manure (K1), cow manure (K2), and goat manure (K3). The second factor is the dose of manure which consists of 3 levels, namely: 10 tons/ha (D1), 15 tons/ha (D2), and 20 tons/ha (D3). Observational data were analyzed by analysis of variance to determine the effect of the treatment on the observed parameters. After knowing the effect of treatment on the observed parameters, it is continued with the Least Significant Difference (BNT) test at the 5% level if it is significantly different. The combination of types and doses of manure significantly affected plant height, number, and leaf area at the age of observation 21 and 28 DAP, number of fruits, and fruit production per plant. The combination of the type of manure and the dose of manures did not significantly affect the number of leaves at 14 days of age, fruit length, fruit diameter, and fruit weight. The combination of goat manure at a dose of 20 tons/ha resulted in the best growth and production of cucumbers.
