Abstract

The purposes of this activity are 1) the diffusion and testing of cultivation agricultural technology to farmers and 2) to know the problems of UPSUS activities and gives solution to solve it. The activities held on April to July 2017 in Wonosobo Regency and the areas which selected are the Wonosobo, Kalikajar and Sapuran District. Methods for this activity are training and assistance of farmer groups, supervision of agricultural machinery and subsidized seeds aid, provision of balanced fertilizers application, arrange of planting season, rehabilitation of tertiary irrigation, supervision of planting realization; land optimization, and demonstration plots. The results of this activity are providing knowledge for farmers about Salibu and organic rice cultivation, balanced fertilizer, planting according to the planting calendar and providing farmer group’s data that will obtain farmer card; providing information to the Department of Agriculture and Food Crop Wonosobo Regency about the agricultural machinery equipment assistance is still not maximized but the activities of providing subsidized seed, balanced fertilizer and rehabilitation tertiary irrigation have been running well. Some problems in the implementation of UPSUS are the time is too short, agricultural machinery equipment aid is not appropriate, the quality of seed aid is not good, the target program of Luas Tambah Tanam is too high and many PPL and farmers do not understand about Salibu. To improve of UPSUS, the government should prioritize the bottom up principle for all kinds of aids or programs; and socialize the new technology system to PPL and farmers.

Abstract

The role of technology is very important in supporting improvement of agricultural production. The high-tech strategic role was demonstrated by the success in achieving increased production of rice within the last 35 years is the contribution of the application of more advanced technology. Mosher et al. (2003) put technology as an essential condition for agricultural development. If there is no change in the technological development of agriculture was halted. Production halted the increase, it may even decline because of declining fertility tannic or because of damage increased by pest play an increasingly rampant. A view to changing the technology, can be interpreted as an adaptive technology on the condition of the biophysical and social environment of the local culture. Practical application of specific technologies by farmers, for example how farmers adjust to the conditions of cultivation of local agro-ecosystem forming a specific production system on irrigated land, rainfed lowland, upland, swampy areas, and tidal. Choice according to agro-ecosystem farmers are adapting cultivation is calibration-specific technologies. It’s caused each commodity grows well on climatic conditions, soil and culture-specific social support. Community service activities has been implementing the specific technology that is enriched with appropriate technology research team of the Faculty of Agriculture of UGM by utilizing site-specific conditions of Ponggok Hamlet, Trimulyo, Jetis, Bantul, which have ingredients that can be used for making fertilizer and also wisdom locations in rice cultivation which has been done by farmers for generations. Community Service Team of Faculty of Agriculture, UGM during 2013-2015 had engaged in community service based on the results of research and appropriate technologies in Ponggok Hamlet, for 2 seasons seen significant progress and participation of farmers. In 2013 the results of the demonstration plot tile average of 6.8 tons/ha, after continuous mentoring and counseling in 2014 the results of tile becomes 7.8 to 9.8 tons/ha. Activities application of appropriate technology in a farmer’s land is not easy. Although guidance and counseling has been done before, but not all farmers want and dare to carry out all of the technology that is recommended because it is still in doubt, especially with regard to plant spacing, seed age and the number of seedlings planted. In 2015, a technology package has been introduced covering healthy seedlings, planting system “footprint tiger”, “tajarwo”, homemade compost with waste around the site and biological fertilizers. The results of the application of specific technologies in the growing season of April to July 2015 showed an increase in rice production, but the farmer as a principal factor remains the key to successful application of the technology.

Abstract

The objective of this study was to determine the changes in the basic soil chemical properties including pH, electrical conductivity (EC), available phosphorus (P), dissolved organic carbon (DOC) and inorganic Nitrogen (NH4+ -N and NO3- -N) after approximately 15-40 years land use change from rice paddy field to orchard, wetland and upland in northeast Japan. Five land use change fields were investigated, including, forest, rice paddy, orchard, wetland and upland near Kumagai shrine, Shonai-machi, Yamagata, Japan. Soil samples were collected from surface layer (0-15 cm) and subsurface layer (15-30 cm) in October 2015. Soil chemical properties of pH, EC, available P, DOC and inorganic N (NH4+ -N and NO3- -N) were analyzed on air-dried samples. The pH increased significantly in the upland after 15 years conversion from rice paddy in both layers, with other land use changes only increasing pH in subsurface layer. EC significantly decreased in the surface layer of orchard and upland fields and in subsurface layers of all the converted fields. Available P significantly decreased in the converted fields, except in the upland subsurface layer. DOC amounts were not significantly different after land use changes from paddy fields. The NH4+ -N decreased significantly only in the surface layer of upland, while NO3- -N increased significantly only in the surface layer of wetland. Significant changes in soil properties were observed after 15 years conversion to upland and 40 years conversion to orchard and wetland from former rice paddy field in this study.

Abstract

The objective of this study was to examine the effect of planting distance of paddy var. Rojolele planted in conventional legowo system and dosage of gamma rays irradiated on nitrogen uptake and productivity of paddy. The experiment was arranged in a randomized complete block design (RCBD) with twelve treatments and three replications. The first factor was gamma ray radiation, consisted of three levels, namely control seed (B0), seed irradiated with gamma rays of 200 gray (B2), and seed irradiated with gamma ray of 300 gray (B3). The second factor was planting distance, consisted of four levels, namely distance of 25 x 25 (J1), distance of 30 x 30 (J2), legowo system of 2 : 1 (J3), and legowo system of 4 : 1 (J4 ). The results showed that jajar legowo system with planting distance of 2 : 1 significantly affected the nutrient content of nitrogen in shoot, nitrogen uptake of plant, and yield  per hectare. Paddy var. Rojolele irradiated by 300 gray produced higher nitrogen content in shoot, nitrogen uptake of plant, and yield per hectare than those in control seeds and seeds irradiated with 200 gray. There was a tendency that planting distance with jajar legowo system resulted in higher grain (yield), on the contrary, the narrow row spacing impacted on lower grain (yield).

Abstract

The available soils for surgarcane plantation is Ultisols. However, the Ultisols has some limitations on its chemical fertility. Efforts to improve the quality of the soil can be done with applying organic matter such as filter cake and bagasse ash resulting from the process of making sugar from sugarcane. This study was proposed to determine the effects of bagasse ash and filter cake to availabilities of NPK in the soil and NPK uptakes by sugarcane, so that they were expected to be able to improve maximum sugarcane growth in Ultisols in Tulang Bawang. This field research used completely randomized design with two factors. The first factor was the bagasse ash doses in four levels: without bagasse ash (A0), 10 ton/ha of dry bagasse ash (A1), 20 ton/ha of dry bagasse ash (A2), and 40 ton/ha of dry bagasse ash (A3). The second factor was the filter cake doses in four levels: without filter cake (B0), 20 ton/ha of dry filter cake (B1), 40 ton/ha of dry filter cake (B2), and 80 ton/ha of dry filter cake (B3). There were a total of 16 combinations of treatment with 3 blocks as repetitions. Data were analyzed by using F-test with 5% significance. When analysis result showed significant differences between treatments, it was then followed by DMR test with 5% significance level for normal data. The results showed that the improvement of NPK status of Ultisols in Lampung might be achieved by applying the filter cake and bagasse ash techniques. Some results of this study showed that treatment of 40 ton/ha bagasse ash for NPK uptakes was significantly different and higher than without bagasse ash treatment. Treatment of 80 ton/ha filter cake for NPK uptakes was significantly different and higher than without filter cake treatment. The highest N uptake (27.84 kg/ha) was in sugarcane at 2 MAP with 80 ton/ha filter cake treatment. The highest P uptake (11.59 kg/ha) was in sugarcane at 2 MAP with 40 ton/ha bagasse ash treatment. The highest K uptake (117.67 kg/ha) was in sugarcane at 8 MAP with 80 ton/ha filter cake treatment. Treatment of 80 ton/ha filter cake influenced significantly to the sugarcane height compared to without filter cake and 20 ton/ha filter cake treatment, but it did not differ significantly compared to 40 ton/ha filter cake treatment. The highest sugarcane (167.99 cm) was at 80 ton/ha filter cake treatment. Filter cake dose treatments did not influence significantly the numbers of saplings and stem diameter of sugarcane aged 8 MAP.

Abstract

Fusarium wilt of shallot is caused by Fusarium solani could affect yield on shallot planting. This research was conducted to study the effect of  addition urea fertilizer on total nitrogen of soil, ammonium, nitrate, nitrogen uptake of foliage and bulbs, and bulbs yield of shallot. This research was conducted at KP4 Kalitirto Berbah and Faculty of  Agriculture, Gadjah Mada University with Randomized Complete Block Design (RCBD) with 2 factors and 4 replications. The first factor was two type of soil which were inoculated soil by Fusarium solani inoculums and sterilized soil by heating  treatment at more than 100 °C at least 3 hours. The second factor was five different dose of urea and KCl fertilizer on percentage (0, 50, 100, 150 and 200) from fertilizer recommendation. The result showed that total nitrogen of soil, ammonium, nitrate in inoculated soil lower  compared to sterilized soil. There is a positive and significant correlation between ammonium and total nitrogen of soil to fresh weight of bulb, the number of bulb and nitrogen uptake of foliage. Likewise, the fresh weight of bulbs and the number of bulb has a positive and highly significant correlation with nitrogen uptake of foliage and nitrogen uptake of bulb.

Abstract

Ultisols is a less fertile soil also esay to soil leaching and erosion can cause lower efficiency of soil nutrient uptakes such as Nitrogen. The objective of this research was to find out the influences of Urea and ZA fertilizers to soil chemical properties, N uptake and sugarcane growth in Seputih Mataram Ultisols in Lampung. The experiment was conducted in a completely randomized design in 2 factors and 3 blocks for repetitions. The first factor was the sugarcane varieties; TC-09 (V1) sugarcane variety and TC-15 (V2) sugarcane variety. The second factor was fertilizer doses and combinations in 7 levels: 0 kg N/ha or without N fertilizer (N0); 100% of urea fertilizer from total of standard dosage of  SGC (151 kgs of N/ha), which is 328 kg Urea/ha (N1); 86% urea and 14% ZA or 283 kg urea/ha and 100 kg ZA/ha (N2); 75% urea and 25% ZA or 246 kg urea/ha and 100 kg ZA/ha (N3); 50% urea and 50% ZA or 164 kg ura/ha and 360 kg ZA/ha (N4); 25% urea and 75% ZA or 82 kg urea/ha and 539 kg ZA/ha (N5); and 100% ZA fertilizer of 719 kg ZA/ha (N6).  This  results showed that Urea at the dosage of 328  without Za  is the most effective and economist combination to increase the weight of sugar-cane per hectare, N uptake of plants, and N efficiency uptake of plants. Additional dosage of ZA increased soil acidity (decreased of soil pH). The study also showed recent that the weight and amount of population per hectare of TC 15 variety are higher than TC 09 variety.
