Abstract

One type of vegetable products in Indonesia is cabbage. However, in the application of  cultivating cabbage vegetables had experience some problems, especially the caterpillar pest is Plutella xylostella. Pest control at the level of farmers in some areas, generally still use chemical pesticides. As a solution for excessive use of chemical pesticides, the use of biological ingredients as bio insecticides was developed. One of the plant material that is easily found in the surrounding environment is beluntas plants which contain alkaloids, flavonoids, saponnins, and tannins. The purpose of this study was to determine the effect of beluntas (Pluchea indica) leaves extract on P. xylostella caterpillar mortality and effect of beluntas extract that forming some phytotoxicity. The results of the research showed that extract if beluntas wasn't sufficiently able to affect the mortality of P. xylostella larvae, however the treatment of beluntas leaf extract with the concentration of 30% was able to suppress the emergence of the imago. In the phytotoxicity test in the field also did not show any phytotoxicity symptoms of giving beluntas leaves extract to the pakcoy plant.

Abstract

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 hektar-1), NK6172 (8,34 ton ha-1), and EFGH (7,13 ton ha-1).

Abstract

Mung beans are one of the common beans comodities consumed after soybeans and peanuts. The national mung bean 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 mulch and crops density gave a real impact to the crops’ height and number of productive branches. Interaction of straw mulch and two crops density increased the crops’ height 37,91% from the control and has the most productive branches. Organic mulch gave real impact to age flowering and number of hardseeds. Husk mulch afford to accelerate age flowering and decrease the number of hardseeds. Organic mulch and number of crop’s density treatments has not afford to improve the yield of mungbean. The yield of mungbean can achieved in this research was 1,54 ton ha-1.

Abstract

In modern agriculture, over use of inorganik fertilizers causes dangerous effects on environment, human health and loss of soil fertility. Soil organik matter is a main indicator of the soils quality and healthy. Organic matter mineralization is a key process that release 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 organik 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 Januari-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.

Abstract

Punung is one of villages in Pacitan Regency which potentially for developing of cocoa, but it produces low seeds quality. This condition is causes by unintensive fertilization and low light intensity coused by shading. The effort to increase cocoa seed quality is by light compensation with the use of nitrogen (N) fertilizer. Purpose of this reseach was to determine of optimum N dosage fertilizer for seed quality. The research by experiment method arranged in Completely Randomized Block Design one factor of varies N dosages (0 as control, 820, 870, and 920 gram plant-1 year-1), level of radiation represented as blocks. Nitrogen fertilization 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 influential positively toward increasing potassium (K) content in leaf tissue at first and second month, while at third  month no influential toward N, P and K content. However there was preference increased N, P and K content in leaf tissue at each month although it had small rise number. In the leaf tissue, there was detected that nitrogen proportion larger than potassium and phosphorus. N fertilizer increased 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 include grade 1.

Abstract

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 are require a large area and long time. Pumpkin cultivation can be done by hydroponic substrates that has advantages including to accelerate the plant growth, quality of plant yields, and can be cultivated on limited area. 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 ratio of Nitrogen and Phosphor) and concentration of hydroponic substrate nutrition solution and interaction between treatments. This research used Completely Randomized Design which consisted of 2 factors, nutritional composition and concentration of solution. Observation variables included flower age, flower position, and number of flowers. The results showed that there were interactions between nutrient composition and concentration of nutrition solution on flower age and flower position. Nutritional composition ratio N-NO3-:P=234:175 ppm tend to give faster period flowering and more pumpkin flowering number. Concentration adjustment of the A-B Mix solutions 20 mL concentrated in 1 L solution gives a better response to accelerate flowering pumpkin.

Abstract

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 repeated 4 times with 3 plants each replication. The results showed that the planting age treatment at 1 month old seed 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 tuber length is 20,5 cm from planting age at 2 months. Tuber weight of treatment planting age 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.

Abstract

The purpose of the research was knowing the response honey pumpkin (Cucurbita moschata Durch) to the giving some kind of natural PGRs substances with various dosages.Theb research was conducted at the Greenhouse of agriculture Faculty Siliwangi University since April 2017 until September 2017, using experiment method with Randomized block  design, 9 treatment, i.e., b0: control, b1: onion bulb 200 ml, b2: onion bulb 300 ml, b3: bamboo shoots 200 ml, b4: bamboo shoots 300 ml, b5: banana 200 ml, banana b6: banana 300 ml, b7: mix (onion bulb + bamboo shoots + banana) 200 ml, b8: mix (onion bulb + bamboo shoots + banana) 300 ml. An each treatmnent is repeated three times. The parameters analyzed were plant height, number of leaves, leaf area, plant dry weight, fruit weight per plant, fruits weight per pieces, fruit length, and fruit diameter. The results showed that honey pumpkin gave the same response to the natural PGRs  with various dosages on  plant height, number of leaves, plant dry weight, fruit weight, fruit length, and fruit diameter. But, honey pumpkin gave the different response on  the leaves area and fruit weight per plant. The largest leaves was found by giving extract of banana bulb of 300 ml  (7119,8 cm2) and the mixture extract (onion bulb + bamboo shoots + banana bulb) of 300 ml (6978, 5 cm2). The highest of  fruit weight per plant is in extract of bamboo shoots 300 ml (388.6 g), and extract of banana bulb 300 ml (347,6 g).
