The application of fertilization and giving organic matter of different causes differences in soil fertility status, with the availability of macro nutrients on a farm, then to know the action proper fertilization. The purpose of this study is to determine the dose fertilization fertility status of the local potential. The research was conducted using a survey method, ie by observing and sampling the soil directly in the field, followed by laboratory analysis to determine the chemical content of the soil. The results showed the level of soil fertility in Wonogiri low fertilizer needs are different in each district in Wonogiri. Areas with low nutrient availability will provide a high dose of fertilizer, and conversely a low fertilization results indicate the availability of nutrient elements in the soil are sufficient for plant growth, although it should still be nurtured to backup next season.

Community awareness in healthy life is increasing by consuming nutritious food through such as fruit. So it is necessary for increasing the availability of fruit either by cultivation expansion or technology development. The production life of papaya crop approximately three years only, so that replanting takes relatively fast. But there is some limitations mainly the availability of suitable seedling (age and uniformity). For improving the availability of suitable papaya seedling can be used gibberellin as growth regulator substance. But gibberellin in pure analysis limitations are expensive, not always available, and high technology in application. The aim of the research was to test of shallot juice (1 kg of shallot bulbs destroyed by juicer) as gibberellin substitute for improving papaya seedling. The experiment was conducted at terrace house, consist of percentage and speed of germination and growth of seedling observation after seed soaked 2 hours in shallot juice several concentration treatment. Test of the germination percentage and speed conducted for 10 seeds on pastur paper in petridish (11.5 diameter) as germination media. The experiment for growth seedling was arranged in randomized completely design which the treatments are: seed soaked in water, soaked in 5, 10, 15, dan 20 ml l-1 shallot juice concentration, and soaked in gibberellin 10 ppm. Each of the experiment unit consist of 8 seedlings which planted on trypot (composite of plastic pots by size 5.5x5.5 cm at surface, 5.5 cm height, and 2,5x2,5 cm at the base, each of traypot consist of 32 pots). So in each of tray pot there are 8 experimental units, each of experimental unit repliclated 3 times. Traypot and petridish at terrace house shaded by woven plastic 65%, by size 2.5x1.5x2.0 m (length, width, and height). Yield of the research showed that shallot juice potential as gibberellin replacement in papaya nursery. Response of papaya seed (percentage and speed of germination) and seedling (length of root, stem diameter, number of leafs, leaf area, and weight of biomass) to 15 ml l-1 shallot juice equal with gibberellin 10 ppm.

Garlic is one of the important horticultural crops in Indonesia so that the needs increas from year to year. In Indonesia plant material (seed) for cultivating garlic always uses comsumption bulb. The impact of that technique in a long time that the yield gradually decrease by virus infection from preliminary crop. The aim of the research was to find out of seed plant material which virus free by in vitro propagation technology. Acclimatitation is one of succesfuly determination in invitro propagation. Research by the experiment was to study the ability of New Tawangmangu, Gunung Kidul, and Bali garlic varieties on acclimatitation in several light intensity (by paranet shading). The results showed that the totipotency of the garlic varieties was high but in acclimatitation by the shading technique just survived two weeks only. The failure of acclimatitation was range of temperature 12-37°C.

Soybean is one of the most important food commodities in Indonesia and also it has high value. The needs continue to increase each year, but not offset by increased production become an issue that must be addressed. One attempt to increase soybean production is through the cultivation in agroforestry systems through improving the quality of soil fertility. This research aims to study the effect of various doses of litter teak and NPK fertilizer on chemical soil fertility and the potential of soybeans yield in agroforestry systems based teak crops. Experiments using a Randomized Complete Block Design (RCBD) with two factors, namely litter teak doses (0 ton ha-1, 2.500 ton ha-1, 5.000 ton ha-1, 7.500 ton ha-1) and doses of NPK fertilizer (60-60-60 and 60-120-60) on Grobogan soybean varieties. The variables measured were pH, organic matter content, N-total soil, cation exchange capacity (CEC), plant tissue of N, P-total soil, and component production. Data analysis using analysis of variance F-test based on the level of 5% and significantly different variables followed by Tukey’s method level of 5%. The results showed that combination treatment with various doses of teak litter NPK fertilizers can increase total nitrogen content of the soil with the highest yield of 1.69% on S1D2 treatment, but to organic matter, CEC, pH, and total soil P not significant effect. Component of soybean varieties of the highest Grobogan of 0.83 tons ha-1 in the treatment S1D1. The result was still below the average of the national soybean production.

Tujuan kegiatan pengabdian adalah memberikan informasi teknologi budidaya padi gogo, jagung dan kacang tanah di bawah tegakan sengon, khususnya dalam perolehan cahaya, sehingga tanaman di bawah tegakan dapat tumbuh dan memberikan hasil yang optimal. Hal ini dilakukan karena selama ini hasil yang diperoleh tanaman di bawah tegakan belum maksimal. Pengabdian diselenggarakan mulai bulan Oktober sampai Desember 2018 di desa Maliran, Kecamatan Ponggok, Kabupaten Blitar dengan melibatkan pihak perhutani dan masyarakat di sekitar hutan (petani agroforestri). Kegiatan pengabdian meliputi pembuatan demplot, penyuluhan dan diskusi (focus group discussion/FGD) yang dilaksanakan di kantor KBH Blitar dengan melibatkan pihak Perhutani dan petani. Pembuatan demplot dilakukan dengan penanaman jagung, padi gogo dan kacang tanah di bawah tegakan sengon umur 3, 4, dan 5 tahun. Hasil FGD diperoleh kesepakatan bahwa diperlukan pemangkasan kanopi pohon bagian bawah sepertiga dari tinggi kanopi. Hal ini diperlukan sebagai upaya menyediakan cahaya bagi tanaman di bawah tegakan saat sengon mencapai umur di atas 3 tahun, sehingga tanaman di bawah tegakan dapat tumbuh dan memberikan hasil yang optimal. Dari hasil demplot menunjukkan padi gogo dan jagung yang ditanam pada tegakan sengon umur lebih dari 3 tahun tanpa pemangkasan tidak memberikan hasil, tetapi kacang tanah masih dapat menghasilkan. Setelah terlibat langsung dalam kegiatan demplot, petani menyatakan bahwa pemangkasan kanopi memberikan wawasan baru dalam melakukan budidaya di bawah tegakan pohon. Selain itu, juga diperoleh informasi bahwa seresah sengon dapat digunakan sebagai pupuk hijau, dan tanaman kacang-kacangan (legum) sangat potensial sebagai tanaman sela, serta tanaman dibawah tegakan dapat digunakan sebagai alternatif sumber pangan organik.
