Abstract

Soybean seeds are orthodox seeds that quickly deteriorate, especially if the storage environment conditions are less favorable (sub optimum). Soaking using coconut water can be done to overcome the deterioration of soybean seeds by utilizing vegetable waste. The purpose of this research was to study the effect of concentration and duration of coconut water soaking on the process of soybean seed germination. This research was conducted in January-February 2020, at the Agronomy Laboratory, Agrotechnology Study Program, Faculty of Agriculture-Livestock. The soybean used in the study was the Dena I variety. Factorial Completely Randomized Design (CRD) with 2 factors was used in this study. Factor 1 was coconut water concentration (K0 = 0% Coconut Water Concentration; K1 = 25% Coconut Water

Abstract

The increasing demand for tomatoes has prompted concerns about the potential decrease in tomato supply, as reflected in rising market prices. To address this issue, efforts should be directed towards enhancing the productivity of tomato plants. This study focuses on identifying the interactive effects of fertilizer type and tomato variety on tomato plant development.Utilizing a Completely Randomized Design (CRD) with two factors, the first factor involves three types of fertilizers (Goat Manure, NPK, and Liquid Organic), while the second factor includes four tomato varieties (Permata, Donna, Serfo F1, and Tinatoon F1). Various parameters, such as plant height, number of leaves, number of branches, stem diameter, number of fruits, and fruit weight, were monitored.The study's results highlight a significant interaction between fertilizer types and tomato varieties, with the NPK fertilizer treatment and the Tinatoon F1 variety demonstrating optimal height among the tomato plants. Notably, NPK fertilizer exhibited a positive influence on tomato plant development, particularly in plant height at weeks 7, 10, and 13, as well as in the number of leaves, number of branches, fruit weight, and stem diameter. In contrast, the type of tomato plant did not significantly impact tomato growth, except for the Tinatoon Variety, which consistently outperformed others in terms of branches, leaves, stem diameter, and fruit weight during the observation period at weeks 7, 10, and 13. These findings underscore the importance of fertilizer selection, specifically favoring NPK, in optimizing tomato plant productivity.

Abstract

Basil is one of the indigenous plants, that has the potential to be used as a plant that is cultivated intensively in Indonesia. Basil include as one of the shrubs that can grow in almost all areas with a fairly dense canopy appearance. Each plant has different growing conditions. Basil can be grown in all regions of Indonesia. The purpose of this study was to identify the response of 2 types of basil against the use of N fertilizer dose on the early growth. In the growth process, plants require sufficient nutrients so that the physiological processes in plants’ organs can be held properly. The nutrients used by plants can be sourced from within the soil itself or in the form of fertilizers that have been put into the soil. Plants will grow properly if the elements needed by plants are fulfilled. Plants need sufficient N, P, and K nutrients for system growth. The elements of N and P are needed in the growth of proteins, carbohydrates, and nucleic acids. Basil plants are leafy vegetable plants that remarkably require Nitrogen in the optimal amounts of the growth process. The research was carried out from February to April 2022 at the Experimental Field of the Faculty of Agriculture and Animal Husbandry at the University of Muhammadiyah Malang. The design used in this study was the factorial Randomized Complete Block Design (RCBD) with a treatment dose of Urea fertilizer in basil type. The results showed that there was no interaction between the types of basil and the dose of urea at all the observation parameters. On the other side, the type of basil affects the parameters of the number of leaves, plant height, and total fresh weight where the type of tidore basil was better than other types of basil. Furthermore, the urea fertilizer dose treatment affected the number of leaves, plant height, and total fresh weight where the better urea fertilizer dose was N125.
