Soil Fertilyty and Minus One Test of Sandy Land For Shallot. Besides to prove the potential of N, P and K nutrients as limiting factors for shallot plants, the objectives of this research was to find out physical characteristics and fertility in sandy land (soils) in Bantul, Kulon Progo district, Special Region of Yogyakarta. Research was carried out in two stages. The first stage was survey and analysis of sandy land in Bantul and Kulon Progo by the age ofamelioration. Survey techniques was based on four age ameliorations of sandy soil. The second stage was conducted using complete randomized block design sigle factor. The second was minus one test of N, P and K consists of five treatments: 1 .TP = no fertilizer (control), 2. PK (-N) = complete fertilizer without N, 3. NK (-P) = complete fertilizerwithout P, 4.NP (-K) = complete fertilizer without K and 5. NPK = complete fertilizer. The results showed that the introduction of amelioration techniques changed and improved soil different changes in physical and chemical of sandy land. Ameliorant addition into the planting media had positive with the percentage change in silt (0.55-2.37%) and clay (0.45-0.51%) increasing significantly, followed by levels P2O5 and lowerring the sand (1.05-2.07%).

Abstract

ABSTRACT Influence of fertilization on soybean’s growth and yield in post-mined land in Central Banka. Ministry of Agriculture focuses to increase soybean production through extensification of  marginal lands such as tin post-mined land. However, the soil fertility is a limitation factor to optimize the marginal land. This study aimed to get an optimum rate of inorganic fertilizer for the growth and production of soybean at the tin post-mined land in Central Bangka. This research was conducted in tin post-mined lowland in the village of Perlang, Central Bangka district from June to September 2015. The study was arranged in a randomized block design (RAK) with inorganic fertilizer treatment dose level, which were urea 50 kg/ha, SP36 125 kg/ha and KCl 50 kg/ha (P1); urea 75 kg/ha, SP36 125 kg/ha and KCl 75 kg/ha (P2); urea 100 kg/ha, SP36 125 kg/ha and KCl 100 kg/ha (P3). The treatment was repeated nine times and it used Wilis soybean variety. The activities consisted of land preparation, early soil data collection, planting, fertilizer application dose treatment, maintenance, observation, harvest and post-harvest. The oberserved parameters were the chemical properties of the soil, growth and yield of soybean. Statistical data was analyzed with analysis of variance. The results showed that the rate of inorganic fertilizer did not significantly affect the plant growth of soybean but significantly affected on the soybeans yield. Fertilizer rate of 100-125-100 kg/ha (Urea-SP36-KCl) gave the highest yield, i.e. 1.16 tonnes/ha compared with the rate of 75-125 -75 kg/ha (Urea-SP36-KCl) and 50-125-50 kg/ha (Urea-SP36-KCl). Fertilization with the rate of 75-125-75 kg/ha Urea-SP36-KCl was the optimum rate in tin post-mined land for soybean crop since it gave the highest MBCR value, i.e. 7.76. fertilization, tin post-mined land, soybean ABSTRAK Kementerian Pertanian telah memfokuskan untuk meningkatkan produksi kedelai dengan ekstensifikasi ke lahan-lahan marginal. Optimalisasi lahan marginal terkendala oleh faktor kesuburan tanah yang rendah sehingga dibutuhkan tambahan pupuk organik dan anorganik. Pengkajian bertujuan untuk mendapatkan dosis pemupukan anorganik yang optimum untuk pertumbuhan dan produksi kedelai di lahan bekas tambang timah. Pengkajian dilakukan di Desa Perlang, Kabupaten Bangka Tengah dari Bulan Juni hingga September 2015, menggunakan rancangan acak kelompok (RAK) dengan perlakuan tiga taraf dosis pupuk anorganik: urea 50 kg/ha, SP36 125 kg/ha, KCl 50 kg/ha (P1); urea 75 kg/ha, SP36 125 kg/ha, KCl 75 kg/ha (P2); urea 100 kg/ha, SP36 125 kg/ha, KCl 100 kg/ha (P3).

Abstract

ABSTRACT Assessment of "Jejer Manten" Planting Technique and Biofertilizer on Rice Farming in Pasawaran District, Lampung Province. One of the efforts to increase productivity is the application of a good planting technique and biofertilizers. Assessment of rice planting techniques and the application of a biological fertilizer was conducted at Sukadadi village, Gedong Tataan district, Pesawaran Regency, Lampung Province, from May to September 2014. Size of each plot was 400 m2 with total area of 1 ha. The objective was to obtain an effective planting techtique and biological fertilizer to increase rice productivity and farmers income on rice farming. The treatments consisted of three factors i.e: planting techniques (S1 = “jajar tegel”, S2 = “jajar legowo” 2:1, and S3 = “jejer manten”) and dosage of biological fertilizers (D1 = 200 kg Urea + 300 kg NPK Phonska; D2 = 100 kg Urea + 150 kg NPK Phonska + 40 kg biological fertilizer; D3 = 200 kg Urea + 300 kg NPK Phonska + 40 kg biological fertilizer). Inpari 10 was used as the variety of rice. The experiment was arranged on the split plot design with three replications. The results showed that plant height and number of tillers produced by “jejer manten” planting technique were high, while length of panicle, number of grains/panicle, hollow of grain, and weight of 1.000 grains were not significantly different for all planting techniques. Rice productivity was not significantly affected by application of the biological fertilizer. Innovation of “jejer manten” planting techniques produced a higher productivity and farmers' income than “jajar tegel” and “jajar legowo” row 2:1 planting techniques. To increase rice productivity, “jejer manten” planting technique is potential to be applied and it does not require an extra cost for planting.   Keyword :rice, “jejer manten”, “jajar tegel”, “jajar legowo” 2:1, biological fertilizer ABSTRAK alah satu upaya peningkatan produktivitas adalah dengan rekayasa cara tanam dan penggunaan pupuk hayati.

Abstract

 The Role of progressive farmers for Farmer Empowerment in West Java. Farmer empowerment is increasingly marginalized by the reduced number of government extension workers in the village. It requires an alternative problem solving to narrow the poverty gap between cities and villages. Extension services providedly of progressive farmer are needed to help farmers. To find study analyze the role of progressive farmer in providing extension services and factor affecting the services contribute advantages to other farmers. A survey was conducted to gather data from 224 respondent who represent progressive farmers in four districts (Bogor, Karawang, Majalengka, and Sukabumi) West Java. Data processing using descriptive technique and regression analysis. The results show that the majority of progressive farmer have a high role as the facilitator of empowerment, motivator, technical assistant, environmental analyzer and marketing partner in farmer empowerment. It proves the effective role of progressive farmer in assisting farmers to obtain the information needed for their agribusiness activity. Farmers are able to cooperate with their community, able to choose innovations that appropriate to their specific location, or apply local innovations existed in their region. The role of progressive farmer  also has a positive effect on the effectiveness level of extension activities from farmers to farmers because they are able to facilitate and bridge the information for farmers from government research institutions and extension agencies.

Perlakuannya sebagai berikut;1) 300 g phonska pupuk anorganik + 150 g urea/pohon; 2) pupuk organik 250 g + 225 g phonska + 112,5 urea/pohon; 3) 500 g pupuk organik +150 g phonska+75 g urea/pohon; 4) 750 g pupuk organik + 75 g phonska + 37,5 g urea/pohon; dan 5) 1.000 g pupuk organik /pohon. Pengamatan dilakukan terhadap (1) pertumbuhan generatif yaitu:bantalan bunga, pentil, jumlah buah, serta (2) hasil, yang meliputi bobot kering biji dan produktivitas tanaman. Hasil penelitian menunjukkan hasil bahwa: (a) pupuk organik dapat dikombinasikan dengan pupuk anorganik, (b) pemberian 250 g pupuk organik + 225 g phonska + 112,5 g urea dan 500 g pupuk organik + 150 g phonska + 75 g urea atau 25%-50% pupuk organik merupakan kombinasi terbaik dan (c) penggunaan pupuk organik pada tanaman kakao secara ekonomi layak dengan B/C >0 atau R/C >1. Penggunaan pupuk organik berperan positif dapat meningkatkan produktivitas kakao melalui pengaruhnya pada pembentukan biji, namun tingkat efektivitasnya terhadap produktivitas tergantung pada keseimbangan dengan dosis pupuk phonska dan urea.Kata kunci: efektivitas, pupuk organik, kakao, lingkungan

Abstract

ABSTRACT Farmers Perception Analysison The Implementation of JajarLegowo Planting System Technology on Rice in Southeast Sulawesi. Jajarlegowo is one of the planting system that introduced by Indonesian Agency for Agricultural Research and Development (IAARD) to increase rice production. The research was conducted to know perception of the farmer, benefit of farm and influencing factors of implementation jajarlegowo planting system technology on rice plant in South East Sulawesi Province.  The research was used survey method for 90 farmers as respondents in Bombana, West Muna and Konawe Regency, South East Sulawesi Province since July to November 2015. The result of research showed that 62.32% of respondents agreed with jajarlegowo technology, 18.85% hesitate and 18.82% reject this technology.  The economic analysis showed that jajarlegowo planting system using drum seeder gave higher benefit Rp16.185.000 per ha per season than other planting systems. Wide area had negative effect but farmer perception gave possitive effect for application of jajarlegowo planting system. Jajarlegowo planting system technology will become one of the most prospective strategy for increasing of rice production in South East Sulawesi, therefore should be conducted through field of demonstration system and also other massive dissemination models.Perception, benefit, jajarlegowo planting system Jajar legowo merupakan salah satu sistem tanam yang diperkenalkan Badan Penelitian dan Pengembangan Pertanian untuk mendorong peningkatan produksi padi. Penelitian di lakukan untuk mengetahui persepsi petani, keuntunganusahatani penerapan teknologi cara tanam jajar legowo dan faktor yang mempengaruhi penerapan teknologi sistem tanam jajar legowo pada tanaman padi di Sulawesi Tenggara. Penelitian menggunakan metode survey terhadap 90 orang responden di Kabupaten Bombana, Muna Barat dan Konawe Provinsi Sulawesi Tenggara, pada Juli – November 2015. Hasil penelitian menunjukkan bahwa 62,32% petani setuju terhadap sistem tanam jajar legowo, 18,85% ragu-ragu dan 18,82% tidak setuju. Hasil analisis ekonomi menunjukkan bahwa sistem tanam jajar legowo dengan menggunakan tabela memberikan pendapatan tertinggi yaitu sebesar Rp 16.185.000,- per musim tanam per ha. Luas lahan berpengaruh negatif, sementara persepsi petani berpengaruh positif terhadap penerapan sistem tanam jajar legowo di tingkat petani. Sistem tanam legowo dapat menjadi salah satu strategi peningkatan produksi padi sawah di Sulawesi Tenggara, oleh karena itu diseminasi teknologi tersebut baik melalui demonstrasi lapangan maupun melalui media diseminasi lainnya perlu terus dilakukan secara massif.
