PENINGKATAN PENDAPATAN PETANI PADI RAWA PASANG SURUT MELALUI PENERAPAN TEKNOLOGI RAISA DI SUMATERA SELATAN

Tidal swamp land has great potential and opportunities to be used as food production areas, especially rice. The IAARD has produced many technologies and varieties that are adaptive in the growing environment of tidal swamps, but their use and distribution have not been widely known and applied by farmers. The research to increase the income of tidal swamp rice farmers is intended to analyze the tidal swamp rice technology that is being developed. Research in Sukamulya Village, sub district Tungkal Ilir, District of Banyuasin, South Sumatera. The research on 2018 dry season, activities began with a pre-survey which was also used to conduct needs and opportunity studies on farmer groups who would apply tidal swamp rice cultivation technology to tidal swamp rice activities using the RAISA technology approach. Data collection is done using with and without method by means of farm record keeping. Farming analysis is used to analyze collected data. Pre-survey results, based on ranking and priority, there are 5 problems that must be immediately implemented and addressed, namely substandard irrigation, rat control, weed control, drought in the constitutional court, and fertilizer dosage. Based on the agreement, the 5 problems will be overcome by mutual cooperation on the cleaning of tertiary channels, integrated rate control, integrated weed control, planting on time, the use of water pumps, rice variety tolerant to drought, and applying fertilizer doses based on kid fertilizer. The average grain yield of farmers cooperator in tidal swamp rice farms of 5,420 kg/ha is 18.86% higher than that of non-cooperator farmers who average 4,560 kg/ha and the level of profit from tidal swamp farming in farmers cooperator is more feasible when compared to non-cooperator farmers.

RESPON PERTUMBUHAN TANAMAN DAN HASIL BEBERAPA VARIETAS PADI SAWAH TADAH HUJAN (Oryza sativa L.) AKIBAT PENERAPAN TEKNOLOGI

Rainfed land with an area of 1.4 million ha is the second rice barn after irrigation land for Indonesia. Understanding rainfed land is land that has a bund but cannot be irrigated with a certain height and time continuously. Therefore the irrigation of rainfed land is largely determined by rainfall so that the risk of drought often occurs in the area during the dry season. So far, rice varieties for rainfed land that have resistant properties to blast disease are still very limited. On the other hand, it is very necessary to diversify the resistant varieties of blast disease to overcome the disease so that the resistance genes are not easily broken. Therefore we need a number of varieties with a wide diversity of resistance genes that are recommended for planting by farmers. The Agricultural Research and Development Agency has released drought-tolerant rainfed lowland rice varieties and several pests and diseases such as Inpari 10, inpari 38, inpari 40, inpari 42, inpari 43 and HHZ5-DT1-DT1 lines. The research method used was Factorial RGD with the treatment of PTT application and conventional technology interacted with rice varieties.The results showed that the application of PTT technology had a real / good influence compared to conventional technology on the growth and yield of rice plants. PTT can increase production by 5.9% and income by 12.6%. Inpari 42, Inpari 43 and HHZ5-DT1-DT1 varieties are relatively more stable than other varieties and Inpari 43 has a higher production compared to other varieties.

developed. This study aims to obtain optimum fertilization technology in several new high yielding rice varieties with high yield potential in new open fields. Research has been carried out in new openings in two locations, namely in West Kalimantan Province, with the criteria for new openings in the first location are new openings less than 5 years old and the second location is openings aged 5-10 years after opening. The study refers to a split plot design with 3 replications. The main plot is fertilization level consisting of (R1) Fertilizer dosage recommendations for new openings, (R2) PTT recommended dosage fertilizers, (R3) Fertilizer dosage way of farmers (local), as plots are (V1) Inpara 9, (V2) Inpari 22, (V3) Inpari 30. Research results show that in new openings of land aged <5 years, inpari 22 has a significant effect on the formation of panicles per clump and percent grains of contents while inpari 30 has an effect on increasing the weight of 1000 grains. In newly opened land of 5-10 years, inpari 22 had a significant effect on the formation of panicles per clump while inpari 30 had an effect on increasing percent grains of content and weight of 1000 grains. The dosage treatment with recommended fertilizer dosages for new openings and inpari 22 has a tendency to produce the highest MPD results in new openings with land age <5 years. The dosage treatment with the recommended PTT fertilizer dosage and inpari 30 variety has a tendency to produce the highest MPD results in new openings with a land age of 5-10 years.

PENGARUH DOSIS PUPUK KANDANG AYAM DAN PUPUK NITROGEN TERHADAP PERTUMBUHAN DAN HASIL SELADA (Lactuca sativa L)

The experiment was conducted to know the effect of chicken manure doses and nitrogen fertilizers on growth and yield of lettuce (Lactuca sativa L). The experiment was conducted at Kutawaringin Village, Selajambe District, Kuningan, West Java Province, from March until May 2018. The experimnetal design was used Randomized Completely Block Design (RBD) with factorial pattern. Each treatment was repeated three times. The treatment consisted two factors. The first factor was rates of chicken manure that consisted four levels : K1 (0 ton/ha), K2 (10 ton/ha), K3 (20 ton/ha), K4 (30 ton/ha), while the second factor was nitrogen fertilizers rates which consist three levels : N1 (77 kg/ha), N2 (100 kg/ha), N3 (123 kg/ha). The result showed that there was an interaction effect between chicken manure doses and nitrogen fertilizers on root volume (28 days after planting), total weight per plant, total weight per plot, and total biomass. Independently, chicken manure doses gave significant effect of plant high, number of leafs, leaf area, relative growth rates (28 and 35 days after planting). While nitrogen fertilizers rates effected plant height, number of leaves, leaf area, net assimilation rates (21 days after planting), relative growth rate (21 and 28 days after planting), root volume (35 days after planting). Chicken manure doses 20 ton/ha and nitrogen fertilizers doses 123 kg/ha gave the best result on total weight per plant and per plot which produces 30,56 g per plant and 638,38 g per plot (2,5 ton/ha).

PENGARUH PUPUK KANDANG DAN INOKULASI MIKORIZA VESIKULAR ARBUSKULAR TERHADAP PERTUMBUHAN DAN HASIL BAWANG MERAH (Allium ascalonicum L)

Fertilizer has a function as being able to improve soil properties and chemistry, as well as soil biology. From the decomposition process, soil fertilizer will produce a topsoil fraction that can be made with soil particles made by soil humus complexes, so that it becomes more stable which will further reduce the rate of air infiltration in the soil. The granting of arbuscular vesicular mycorrhizae inoculation is one of the collaborative works of fungi, soil and plant roots which supports the supply of nutrients for plants, improves soil structure, and provides resources to promote unfavorable plant growth. The purpose of this study was to study the best interaction between the dose of fertilizer and mycorrhizal VA on the growth and yield of shallots. The design used was an experimental method with randomized block design (RBD). This study consisted of two factors, namely the dose of chicken fertilizer and the arbuscular vesicular mycorrhiza inoculation. The 15 ton / ha fertilizer application showed the best increase in red 3.90 kg / plot or equal to 17.33 tons / ha and the arbuscular vesicular mycorrhizae 4 tons / ha showed the best results on the growth and yield of shallots on dry weight tubers per plot which produces 3.60 kg / plot or the equivalent of an average yield of 16 tons / ha.
