Abstract

Cocoa (Theobroma cacao L.) is a plantation commodity with high economic value. The need for cacao is increasing but the production yields are decreasing every year, so it is necessary to increase cocoa production. The purpose of this study was to find out how the application of liquid organic fertilizer can increase the growth of cocoa plants and how to apply liquid organic fertilizer to cocoa plants. The research was carried out in several stages, namely making liquid organic fertilizer and planting cocoa plants. This study used a randomized block design with the Least Significant Difference (LSD) test. The results showed that the application of liquid organic fertilizer to cocoa seedling plants had an effect on growth and gave better results than without the application of liquid organic fertilizer. The highest yield was found in the 500 mL/L treatment with an average plant height of 20.67 cm, leaf area of 28.49 cm and an average number of leaves of 5.67.

Abstract

Corn (Zea mays L.) is one of the important food crops in Indonesia and has a strategic role in the Indonesian national economy as the main food crop which not only provides food, but is also a source of animal feed and industrial raw materials. This research aims to determine the effect of applying liquid organic fertilizer from goat manure to increase the growth of corn plants (Zea mays L.). This study used a randomized block design consisting of four treatments and three replications, namely control treatment (J0), 50 mL/L (J1), 100 mL/L (J2) and 150 mL/L (J3). The research stages are preparation of materials, making liquid organic fertilizer from goat manure, planting corn, applying liquid organic fertilizer and maintenance. The results of research on plant height parameters showed that the highest plant height was in treatment J3 (150 mL/L) at 110.67 cm. The highest number of leaves was found in treatments J3 (150 mL/L) and J2 (100 mL/L), amounting to 10.00 and 10.67. The highest leaf area was in treatment J3 (150 mL/L) at 820.25 cm. Goat manure liquid fertilizer contains the nutrients N, P and K that plants need for plant height, number of leaves and leaf area. Key words: corn seeds, goat manure, fertilizer

Abstract

High seed vigor is one of the determining factors for the successful early growth of rice (Oryza sativa L.). However, drought stress often becomes a constraint in rice cultivation because it can inhibit water imbibition, reduce germination, growth synchrony and decrease the vigor index. Therefore, efforts are needed to maintain seed vigor in water limited conditions, one of which is through the application of liquid organic fertilizer (LOF) from goat manure. This study aims to examine the effect of the application of liquid organic fertilizer from goat manure on rice seed vigor under drought conditions. The parameters observed were germination power, growth synchrony and vigor index. The results showed that the application of 50 mL and 100 mL of goat manure LOF had a significant effect on germination power, growth synchrony and vigor index. This is because the organic acid content from the fermentation of LOF is able to dissolve and wash out some of the dissolved salts. Goat manure organic fertilizer (LOF) contains macronutrients (N, P, K), micronutrients and fermented organic compounds that support seed metabolism, stimulate root growth and improve plant adaptation to drought conditions. Keywords: Seed Vigor, Drought, Rice (Oryza sativa L.), Goat Manure Liquid Organic Fertilizer
