Abstract

Chilli (Capsicum annum L.) is a horticulture comodities that high demand because it has a high economic value. The demand of Chilli increase every year as the population grows and the industry grows which requires Chilli as raw materials. The productivity of red chili in Jember Regency is also low, which is only 87.68 quintals hectare-1. Fluctuations in red chili production that occurred in the Jember area were caused by several things including an unsupportive environment such as declining soil fertility, high pest attacks, and excessive use of pesticides. Therefore there is a need for agricultural development in order to be able to meet food needs and increase export opportunities to neighboring countries. The parameters observed in this study were secondary data from the soil unit map. The secondary data referred to are soil drainage, soil depth in cm, slope related to erosion, altitude, standing water, soil cation exchange capacity, and soil pH. The improvement efforts made to improve the land suitability class is by setting the spacing, giving organic matter, agricultural lime, P fertilization, cutting and filling the land with a mound terrace system or bench terrace to reduce soil erosion.

Abstract

Provision of nutrients is one of the important things in plant cultivation. One of the nutrients that can be obtained from organic fertilizers. Manure is one type of organic fertilizer that can increase soil nutrients. The manure used in the media is cow and goat manure. In addition to manure, the application of Liquid Organic Fertilizer (POC) of lamtoro leaves can also provide nitrogen elements in the soil. The element nitrogen has good benefits for nurseries because it can accelerate vegetative growth in plants. The purpose of this study was to determine the effect of adding manure media by giving lamtoro leaf POC to vanilla seeds. This research was carried out at the Jember State Polytechnic in July – November 2020. This study used a factorial randomized block design with two factors, namely the first factor was 3 types of planting media consisting of control, addition of cow kendang fertilizer and addition of cow kendang fertilizer. Then the second factor was giving lamtoro leaf liquid organic fertilizer with three levels consisting of control, 25%, and 50%.. The results showed that goat manure showed the best results in increasing shoot length, shoot diameter, leaf width and wet weight of vanilla plants. Application of liquid organic fertilizer with a concentration of 50% gave the best results for increasing shoot length, shoot diameter and wet weight of vanilla plants.
