Mung beans are one of the common beans comodities consumed after soybeans and peanuts. The national mung beans production was 0.7 tons in average, which is lower than the potential yield. Production of mung bean can be improved by modifying the microclimate by mulching and regulating crop density. The purpose of this research was to improve the yield of mungbean. Research method used was Completely Randomized Design (CRD). The treatments were organic mulching of mahagony leaves, straws, husks, and without mulch (M1, M2, M3, M0) and the crops density 1 and 2 crops (B1 and B2). The results showed interaction between organic mulches and crops density significantly affected the crops’ height and number of productive branches. Interaction of straw mulches and two crops density increased the crops’ height 37,91% than the control and has the most productive branches. Organic mulches significantly affected to flowering period and number of hardseeds. Husk mulches accelerated flowering period and decrease the number of hardseeds. Organic mulch and number of crop’s density treatments has not to improve the yield of mungbean yet. The yield of mungbean can achieved in this research was 1,54 ton ha-1.

In modern agriculture, over use of inorganik fertilizers causes dangerous effects on environment, human health and loss of soil fertility. Soil organic matter is a main indicator of the quality and healthy soils. Organic matter mineralization is a key process that releasing the available nutrients to the plants. There are many organisms involved in the mineralization processes. Earthworm enable to digest soil organik matters, and the excretion’s have more available nutrients content, that potential to increase nutrients absorption. This research intended to study influences of organic fertilizers residuals and earthworm introduction on growth of the upland rice in pots. The experiment was conducted in Agricultural Faculty of Universitas Islam Nusantara (UNINUS), from January – June 2017, with RBD that comprised of two factors: (1) earthworm; and (2) residual of kinds and rates of the organik fertilizers. The results showed that aren’t significantly interaction influences of the organik fertilizers residuals and earthworm introduction on growth and yield of upland rice also to increase yield components of upland rice.

Punung is a village in Pacitan Regency which potentiall for cultivating of cocoa, on the contrary it produces low seeds quality. This condition is caused by unintensive fertilization and low light intensity caused by shading. The effort to increase cocoa seed quality was by light compensation and the use of nitrogen (N) fertilizer. The purpose of this reseach was to determine of optimum N dosage fertilizer for inproving seed quality. The research was arranged in Completely Randomized Block Design with one factor which is the varies N dosages (0 as control, 820, 870, and 920 gram plant-1 year-1), level of radiation represented as blocks. Nitrogen fertilization was applicated three times. Fertilization of P (SP36) and K (KCl), 1390 and 1000 gram tree-1 year-1 respectively. The observation variables are soil character, micro climate, leaf anatomi, physical and chemical seed quality. The result showed that N fertilizer influenced positively toward increasing potassium (K) content in leaf tissue on the first and second month, while on the third month no significant influence toward N, P and K content. However there was preference of increased N, P and K content in leaf tissue on each month although in small rise number. In the leaves tissue, there was detected that nitrogen proportion was larger than potassium and phosphorus. N fertilizer increased the physical and chemical seed quality (protein and fat content). Optimum dosage was 870 gram tree-1 year-1, highest weight of 100 seed (146 gram) and seed quality was categorized as grade 1.

Pumpkin is a promising commodity to be developed as food substitute for flour-based flour. Pumpkin cultivation is currently cultivated by farmers on dry land as secondary crop. Pumpkin cultivation constraints as requires a large area and long time. Pumpkin commodities development can be done by hydroponic substrates cultivation that have advantages to accelerate the plant growth, can be cultivated on limited area, and increase the quality of plant yields. The hydroponic substrate cultivation depends on the quality of nutrients as well as the availability of the nutrients. The aim of this research is to study the response of plant flowering to the composition of nutrients (modification of the balance of Nitrogen and Phosphor) and concentration of hydroponic substrate nutrition solution and interaction between treatments. This research used Completely Randomized Design which consists of 2 factors, nutritional composition and concentration of solution with 3 replications and each treatment consist of 6 plants. Observation variables included flower age, flower position, and number of flowers. The results showed that there were interactions between the treatment of nutrient composition and adjustment concentration on the observing variables flower age appear, and flower position. Nutritional composition with the balance of elements of Phosphorus and Nitrogen shows the higher balance of Phosphorus elements followed by lower Nitrogen elements tend to give a lower response to flowering pumpkin on hydroponic substrate. Adjustment lower concentration of application solutions (20 ml concentrated in 1 L solution) or equivalent to EC 3.8-4.0 mS/cm gives a better response to flowering pumpkin on hydroponic substrate.

Arrowroot (Marantha arundinacea) is potential plant to be developed in Indonesia. Arrowroot usually grows wild without special treatment so that makes the productivity is low. The purpose of research was to find the suitable planting age and seeds origin of arrowroot. The research was conducted from October 2016 to November 2017 at Experimental Field of Agriculture Faculty of Universitas Sebelas Maret. The research used RCBD (Randomized Completed Block Design) with two factors.The treatment of planting age consist of 3 levels (1 month, 2 months, 3 months) and seeds origin consist of 2 levels (tuber seeds and seed of nursery), each is repeated 4 times with 3 plants each replication. The results showed that the planting age treatment at 1 month of planting age has the better result compared with other treatments in almost every variables observed i.e plant height, number of tillers, tuber lenght, diameter tuber, and tuber weight per plant. The number of leaves,fresh weight plant, dry weight plant, and number of tubers are not significantly different at 1 month of planting age, although the plant is higher. The highest lenght of tuber is 20,5 cm from 2 months of planting age. Tuber weight of planting age treatment reached 31,8–124,9 gram per plant. Seed of nursery showed better results than tuber seeds although not significanly different. Between planting age and origin of seeds was no interaction.

One type of vegetable products in Indonesia is cabbage. However, in the application of cultivating cabbage vegetables had experienced some problems, especially the crop caterpillar of Plutella xylostella. Pest control at the level of farmers in some areas, generally they still use chemical pesticides. As a solution for excessive use of chemical pesticides, the use of botanical insecticides is interesting to develop. One of the plant materials that is easily found in the surrounding environment is “beluntas” leaf (Pluchea indica L) containing alkaloids, flavonoids, saponnins, and tannins. The purpose of this study was to determine the effect of leaves extract of (P. indica) on caterpillar mortality of P. xylostella and the phytotoxicity effect on pakcoy. The results of the research showed that the extract wasn't sufficiently able to affect the larvae mortality of P. xylostella, The treatment concentration of 30% however was able to suppress the emergence of the imago. The extract did not show any phytotoxicity symptom the pakcoy .

Maize (Zea mays L.) is the second most important cereal crop of Indonesia after rice. The productivity of corn in Central Java province in 2015 was increased that considered as relatively low. Maize productivitiy needs to be improved to supply the requirement of people through of plant spacing and use the hybrid maize varieties. The aims of study was to determine the effectiveness level of plant spacing, to test the best hybrid maize varieties, and test the combination of two treatments to optimize the yield potential hybrid maize. This study has been conducted from June until October 2017, at Desa Srimartani, Kecamatan Piyungan, Kabupaten Bantul, Daerah Istimewa Yogyakarta. This study was arranged in Split Plot Design consisting of two factors that have been researched, varieties (ABCD, EFGH, NK6172, P27 and DK77) and plant spacing (70 x 20 cm, 75 x 20 cm, and 75 x 25 cm). The results show that treatment of varieties mostly can increase all of variable analysis but there is no interaction on both treatment except plant height, fresh and dry biomass weight. Variable of plant height, tasseling and silking, cob weight with husk, cob weight without husk, kernel seeds weight per plot, 100 seeds weight, yields per hectare show that the highest average is variety of P27. While treatment of plant spacing has no effect because the interval between treatments plant spacing is too close therefore it shows insignificantly different result. The highest dry kernel product on variety treatment P27 (8,82 ton ha-1), followed by DK77 (8,53 ton ha-1), ABCD (8,50 ton ha1), NK6172 (8,34 ton ha-1), and EFGH (7,13 ton ha-1).
