Abstract

The experiment aimed to know the best inoculant and incubation time of organic fertilizer to the growth and yield of paddy. The experiment was conducted in Kasihan, Bantul, Yogyakarta. The altitude of experiment site is 110 m above sea level with the soil type of regosol.The experiment used the 3 x 4 factorial with one control and was arranged in Randomized Completely Block Design with three block as replication. The first factor was kind of inoculant to make organic fertilizer, consisted of 3 levels i.e (1) without inoculant, (2) EM4 and (3) Stardec. The second factor was incubation time, consisted of 4 levels i.e (1) 7 days, (2) 14 days, (3) 21 days and (4) 28 days. The control used organic fertilizer (Urea, SP36, KCl) with recommended dose.The result showed that neither organic fertilizer without inoculant nor with addition of EM4 and Stardec (with incubation time 7-28 days) affected significantly to the growth and yield of paddy, the used 3ton/hectare of organic fertilizer with or without inoculant did not affect significantly to the yield of paddy.

Abstract

This research was addressed to study the effect of plant growth media composition and nutrients concentration on yield of Cucumis melo L. The research was designed in complete factorial test of 4x4 with three replicates. Mixed growth media of bokashi:cocopeat:husk charcoal were tested in four compositions, i.e. 90%:5%:5% (M1), 80%:10%:10%(M2), 70%:15%:15% (M3) and 60%:20%:20% (M4) respectively. The other tested factor was nutrients concentraion that consists of four levels, i.e. control/no nutrient given (K0), 2 g/L (K1), 4 g/L (K2) and 6 g/L (K3). The Action 434 variety of Cucumis melo L. seedlings were then transplanted into 10 kg’s polybag and allowed to grow till harvested. The results showed that Chlorophyll content of M1 plants were higher than others, but the highest sugar content was resulted by M3 plants, and the highest thick of flesh fruit was resulted by interaction 60% bokashi:20% cocopeat:20% husk charcoal with 4 g/L nutrient concentration.

Abstract

Bondowoso tobacco is a type of  sliced tobacco that is developed in eleven district i.e. Bondowoso, Tenggarang, Tegal Ampel, Pakem, Curahdami, Maesan, Pujer, Wonosari, Binakal, Taman Krocok and Wringin. In order to fulfill the improvement of new variety program, yield evaluations is a step that should be done. The aims of the experiment were to examine the yield of local varieties, the superior traits and then choose the best variety. The experiment was conducted on March to September 2009 in tobacco producing areas. The experiment tested 6 local  varieties i.e. Sam1, Se2, Mar3, Sam4, Sam5 and Sam6. Each of them was plant with three replicates. The experiment design was  randomized complete block design (RCBD). Each plot consisted of 200 plants. The result showed that three varieties of which relatively had the same superiority on characters: yield potensial, quality index, plant index, nicotine content and disease tolerance. The selected varieties were Sam1, Sam5 dan Sam6, with yield potensial each acession i.e: 1.682 kg/ha, 1.399 kg/ha and 1.282 kg/ ha.

Abstract

A study on the effect of length time shading (approx 70 % of sun rise intensity) to the growth and yield of Camar mung bean variety was conducted in Nogotirto, Gamping, Yogyakarta. The experiment was arranged in a Randomized Complete Block Design with 3 replications. The treatment were 6 levels of length and time of shading of Camar mung bean variety, i.e.: shading at the whole life cycles (A), the first half life cycles (B), the second half life cycles (C), the first quarter life cycles (D), the second quarter life cycles (E) and no shading at the whole life cycles or control (F).The result showed that the length and time of shading affected the growth and yield of Camar mung bean variety significantly except for the number of root - pimples, the number of effective root - pimples and weight of 100 grain per plant parameters. In accordance with the control, the shading at the first quarter and second quarter or at last life cycles gave no significant different in the growth and yield. The yield of that treatments ware 1.77, 1.72 and 1.82 tons seed per hectare. While in accordance with the control, the shading at the first half, the second half and at the whole life cycles gave the lower growth and yields. The decreasing at the yields were 28.95, 32.96 and 42.36 %.

Abstract

Spodoptera litura is a major pest in soybean cultivation causing damage by 80%. One of control is done  by using bintaro plants (Cerbera manghas) potential as a botanical pesticide (insecticide). This study aims to determine the effectiveness of botanical pesticide from bintaro extract and get the precise extract concentration of fruit, young leaves, and old leaves of bintaro to control Spodoptera litura on soybean plants, and its influence to  the growth of soybean plants. This study used an experimental method that is designed in a single factor completely randomized design using pesticides Bintaro (young leaves, old leaves, and fruit), which consists of three concentrations (100 g / l, 200 g / l, and 300 g / l), add two treatments, namely, sprayed with water and a  synthetic pesticides as a control. Result showed the leaves and fruit of Bintaro at concentrations of 100 g/ l to 300 g/ l by solvent extraction has not been effectively used as botanical pesticide to control Spodoptera litura on soybean plants. Old leaf Bintaro extract (100 g/ l) produces highest pest mortality value and  rate of 40.00% and 2.00. The use of botanical pesticide from extract bintaro (fruit and leaf) is not inhibit the growth of soybean plants.

Abstract

The eruption of Mount Merapi had been giving adverse effect for the community, but on the other hand, there are great benefits in it such as the enrichment back to the land. Enrichment process in land with materials that are rich in nutrients is often known as rejuvenation. In general, the rocks containing certain minerals or mineral assemblages, which has large amount of the potential nutrient that can be used by plants in the form of weathered minerals. Therefore, it is a big question about the relationship between primer mineral deposits on Mount Merapi volcanic material with the potential nutrient for crop. The results showed that the identification of Merapi pyroclastic material derived from basaltic andesite magma with primary mineral content easily weathered the dominant form of plagioclase. Utilization of volcanic material as macromineral is easy to use, because the nutrient content of the existing potential in minerals included in the group of minerals that easily weathered.

Abstract

In Sumedang, local variety of groundnut DM Situraja has a great potential and showed increasing production rates. This support the agribusiness development of groundnut in Sumedang District and surrounding areas. The objective of this experiment was to determine production potential of local variety groundnut Situraja especially in Sumedang. This research was arranged in a randomized complete block design whereas each treatment was replicated 4 times. The data were analyzed using SPSS version 16 and treatment means were separated using LSD (Least Significant Difference) with 5% error level. The results indicated that morphology of Situraja variety had an upright growth habit, rod-shaped and green purplefish, 2-seeded, and seed weight 40-55 g for 100 seeds, maturing age of 90 days, and the production potential 3,02 t/ha. The content of oil was 45%, with a relatively high protein content of 28% and crunchy sweet taste. High productivity of DM Situraja local variety was resulted by interaction between variety and spesific enviroment.
