Clove leaf (Syzygium aromaticum L.) is one of the plants that have the potential as a vegetable insecticide to control pests. This study aims to obtain the concentration of clove leaf extract (S. aromaticum) with organi…
ABSTRACT Soybean (Glycine max (L.) Merr.) is a legume crop. Soybean productivity continues to decline, one of the reasons being the declining level of soil fertility. Efforts to increase the productivity of soybean plants by compensating the application of organic matter and inorganic fertilizers from empty oil palm fruit bunches with cellulolytic microbes and N, P, K fertilizers. This researc…
ABSTRACT Onions that are cultivated on inceptisol soils have the main constraints, namely low soil fertility and low organic matter content. The efforts to overcome these problems can be done by giving liquid organic fertilizer and rock phosphate. This reserach aims to determine the interaction of Gamal leaf LOF and RP fertilizer and to determine the best concentration of Gamal leaf LOF an…
ABSTRACT This study aims to obtain the best combination dose of NPK fertilizer with organic fertilizer and biofertilizer on the growth and production of sweet corn (Zea mays saccharata Sturt.) in reducing the use of NPK fertilizer. The study used a completely randomized design (CRD) with six treatments repeated four times resulting in 24 experimental units. Each experimental unit consisted of …
ABSTRACT Sweet corn (Zea mays saccharata Sturt.) is very popular because it tastes delicious, savory and sweet and can be processed into various kinds of food. The demand for sweet corn is increasing in line with the increase in population and various processed foods derived from sweet corn. Efforts to increase sweet corn production by extensification, namely the program to expand the plan…
ABSTRACT Corn is the second important food ingredient in Indonesia after rice. The main problem in corn cultivation is the attack of Spodoptera frugiperda J.E. Smith. Botanical pesticide neem leaf flour extract Azadiractha indica A. Juss can be the alternative to control S. frugiperda in a safe way. The purpose of this study was to obtain an effective concentration flour extract of neem leaf t…
ABSTRACT Mungbean plants are one of the most important food crops for the community after soybeans. Generally, farmers use inorganic fertilizers continuously which can have an impact on reducing soil fertility. Efforts can be made to increase the production of mungbean plants, one of which is by applying Bacillus cereus biofertilizer. This research was conducted experimentally using a complete…
