Water availability is main constraint to optimalization dry land condition for agriculture development. Therefore innovation technology for water utilization is need. The aims of this study is to determine function of mulch and soil ameandment base of bio-char for improving soil physics, especially for water holding capacity, and to increased productivity and fertilizer efficiency. Filed experiment was conducted in dry land Exp. Station Naibonat, Kupang, during 2010 and 2011. Randomized Block Design was used with three replications. There five treatment was applied such as: control, mulch surface, mulch + soil amandment, vertical mulch, vertical mulch + soil amandment. The result showed that mulch and soil amandment gave significantly effect on growth and yield of Maize. It is also indicated that application of vertical mulch + soil amandment gave a good growth and yield. At extreme condition application mulch and soil amandment did not improve growth and yield of Maize. Application of bio-char as soil amandment in the long-run will improve utilization of organic fertilizer and to support carbon conservation in the soil

One of the horticulture commodity able to take role in agricultural development is string bean. In Sub-Province Lamongan, centre production of string bean is District Babat, Sekaran, Laren and Kedung Pring with productivity; level 15,0 t/ha. Result of research indicate there is two, system marketing of string bean in Village Kuripan, and channel marketing I (entangle farmer, merchant mount countryside/supermarket and wholesaler), channel II (entangle farmer, compiler merchant mount supermarket and district). Executed by marketing function that is transfer function which consist of purchasing, sale and physical function (depository and transportation function, and also facility function that is market information). Efficiency marketing value at channel marketing of I (0.26%), relative lower if compared to marketing efficiency value at channel marketing of II (3.17%). It is assume channel marketing of I relative more efficient because efficiency value smaller than II channel and its marketing marjin also smaller relative

The low level of farms income from agricultural sector mainly happens in dry season had to inappropriate soil cultivation. The utilization of soil for brick ste manufacturing is one of this case. The excavation process occurs on top soil inflicting degradation of soil fertility. Soil in the impact of this condition has a problem in providing chemical element for the agriculture, especially the lack of N. One of alternative attempts to increase the soil fertility in providing N on formerly brick ste excavation-soil is by supplying Petroganik fertilizer and compost. Petroganik and compost is an organic fertilizer containing N, P, K, the other nutrient, similar to the other organic fertilizers. The aims of the research are to determine the effect Petroganik fertilizer and compost application on N uptake and toward the growth of corn on former brick ste excavation-soil, and to know the chosen dosage which is resulting in growth and N uptake of corn. Research used is Random Block Design with 9 treatment and 3 replication. Dosage of treatment T0 : Control, Petroganik (14, 17, 20, 23) t/ha and compost (14, 17, 20, 23) t/ha. Indicator plant was used Hybrid Corn BISI 2. The result of experiment showed that : 1. Significant effect in increasing uptake of N the corn. The treatment of Petroganik 17 t/ha (P2) increasing 145 % and compost 14 t/ha (P2) increasing 93.8 %, 2. Insignificant effect on plant growth (height, number of leaf) However, it gives significant effect on dry weight of the corn biomass. The treatment Petroganik 17 t/ha (P2), increases 101.45 %, 3. The application of Petroganik fertilizer is more effective in increasing the growth and N uptake of corn than that of compost since the application of 17 t/ha of Petroganik has already increased the N uptake and growth of corn .

Cigarette industries in Indonesia especially nowadays still need to import some raw ingredients. The highest import for 10 years (2001-2010) is from China i.e. for about 28,288,197 ton/year or 53.38% from import total of the total import of 52,999,855 kg/year with a value of USD 127.149.050/year. The price of dried tobacco leaves from China is only USD 1,996/kg or 83.84% from the average price of import dried tobacco leaves. Base on these data, it is showed that most local cigarette industries need to have dried tobacco leaves with medium quality and low price. Opportunity for East Java to develop virginia tobacco is high enough. East Java not only has quite potential area, but also has technology packages which are sufficient enough to increase productivity up to 2,000kg/ha or more. The weakness is the system for guiding farmers. There is no link in the technology partnership, production tools, furthermore marketing resulted in low productivity and quality. As a fancy product there should be a link between farmers as producers and tobacco industries as consumers for all sub-systems of virginia tobacco farming business. Cooperation of producers, consumers, and local governments is the basic framework of the system for guiding. Producers and consumers had more cooperation in the aspects of production and quality improvement. Local government regulations governed on all parties working together based on justice. Farmers as producers are obliged to apply the technology built and sell dried tobacco leaves according to the company's pricing agreement builder

Improved management of dryland agriculture could be one strategy to increase cassava production in order to meet national demand particularly for food and bioetanol industry. A field experiment was carried out to evaluate the influence of biomass modification addition (biochar, cattle manure, and corn-straw) on the growth and yield of cassava grown on sandy soils of northern Lombok. The treatments tested were: without addition of organic biomas as control (M0); the straw was put in the lowest part of rhyzoshere, biochar in the middle and subsequently followed by manure mixed with soil on top (M1); biochar, cattle manure, straw were mixed thoroughly within rhyzosphre (M2); biochar and cattle manure were only mixed with soil (M3); the manure was put down in the bottom part of rhyzoshere, straw in the middle and subsequently followed by biochar mixed with soil on top (M4). Results of the research showed that modification of biomass addition (biochar, manure and corn-straw) within soil increased significantly the growth and yiled as a results of better nutrient retention compared to soil without organic addition. The yield was increased by 32 and 33% at M1 and M4 respectivelly and reached closed to 40% at treatments of both M2 and M3 (27 t/ha)

The objectives of this research was leaning and finding the consentrade of IAA (Indole Acetic Acid) on vegetative growth of Phalaenopsis sp. The research used a randomly completely block design consisting of five treatments on level IAA consentration : 0 mg/l (A0), 100 mg/l (A1), 200 mg/l (A2), 300 mg/l (A3) and 400 mg/l (A4). Every treatment was replicated five times. The observed parameters included the amount of increasing leaves, the length and width of lives, the amount of increasing roots and the length of increasing roots. The results showed that the consentrade 400 mg/l IAA was the most appropriate consentrade to stimulated on vegetative growth of Phalaenopsis sp. The length of increasing leaves was 0,93 cm and the amount of increasing roots was 3,90

The performance of improved sweetpotato clones (Ipomoea batatas (L.) Lamb) in two location reported in this studies. The first location at Jatikerto-Malang Regency, from March to August 2012 and second at Sambigede-Blitar Regency, from April to September 2012. Both of the trials were done with a randomized complete block design with 3 replications. The experimental material consisted of nine sweetpotato clones. All the clones were planted in a plot size 5 m x 5 m, consisted of four rows with 75 cm between the rows, 25 cm spacing between plants within the row. The experimental plots received 100 kg N, 20 kg P2O5, and 75 kg K2O/ha in the form of Urea, SP-36 and KCl. Roots were harvested four months after transplanting. Fresh storage root yield and protein content presented in this report. Fresh storage root yield is significantly influenced by location, among improved clones ranging 7 to 21 t/ha in Malang and 5 to 18 t/ha in Blitar, two clones of them to reach 114 to 161% higher to control variety, Boko. On the contrary with protein content is not sensitive on differ locations, among improved clones ranging 6 to 7,63% dry weight basis
