Bacterial leaf blight disease is an economically important disease for the growth of rice plants. The research was aimed to know the most resistant varieties to bacterial (Xanthomonas oryzae pv. oryzae) in seedling phase. The research was conducted May up to Juli 2012 at Green House Livestock, Agriculture and Horticulture UPTD Serang city. The research used a Randomized Completely Blok Design (RCBD) with one factor, each one tray planted 3 varieties. Test varieties were planted in the middle, on the right was susceptible variety (IR-64) and to the left of the comparison resistant variety (Conde). Each variety was planted 10 seeds, so there were 30 rice stalks. There were 10 trays experiment, with 3 replications. Overall there were 30 trays trial. Results of research showed that from 10 varieties had tested, levels of resistance to bacterial leaf blight disease (BLB) in seedling phase were: (1) Waler 17,56 %, (2) Tambleg 18,46 %, (3) Kewal Bulu Hideng 20, 43 %, (4) Gadog 20,84 %, (5) Jaketra 21,58 %, (6) Kewal Cere 23,65 %, (7) Ketan Laleur 25,80 %, (8) Jalawara Hawara 26,29 %, (9) Ketan Solo 29,20 %, (10) Kewal Gudril 29,93 %. The fastest BLB incubation period was local variety of Kewal Gudril within 4-5 days.Key words : Local Varieties of Banten, Bacterial Leaf Blight, Xanthomonas oryzae pv. oryzae, Resistance and Disease Intensity.

The aim of this research was to know In Vitro initiation on shoots of marasi (Curculigo latifolia) by different concentration of NAA(Naphthalene Acetic Acid) And BAP (Benzyl Amino Purine). This research has been done at Biotechnology Laboratory of Agriculture Faculty, Sultan Ageng Tirtayasa University since August to October 2014. This research used Randomized Complete Design (RCD) with two factors. The first factor was NAA concentration with 4 levels, they were mg/l; 0,2 mg/l; 0,4 mg/l; 0,6 mg/l. The second factor was BAP concentration with 4 levels, they were 0 mg/l; 0,5 mg/l; 1 mg/l; 1,5 mg/l. The research showed that the NAA concentration gave significant effect on plant height at 4, 5, 6 and 7 WAP (Week after planting), and the BAP concentration gave significant effect on plant height at 7 WAP. There were not combination effect on NAA and BAP concentration on bud initiation time and plant height. All the living explants during the observation reached 83,5% with the number of contaminating explants was 60% and browning explants 87,5%.

Tomato plants require intensive cultivation techniques to growth and high production. The use of fertilizers is one of the techniques that need to be developed. This study aimed to determine the effect of bokashi and urea fertilizer on the growth and production of tomato plants. The treatments tested is bokashi the dose of 0 or without bokashi, 10 ton Bokashi ha-1, and 20 ton bokashi ha-1, and urea that doses of 0 or without urea, 200 kg urea ha-1 and 400 kg urea ha-1. The study was designed using a randomized block design, two factors with three replications. The results showed that administration of bokashi fertilizer and urea together can cause interaction effects increased plant height, number of fruits per plant and fruit weight per plant, and a dose combination bokashi and urea best is 20 tons bokashi ha-1 and 400 kg urea ha-1.

ABSTRACT The research was aimed to know genetic potential of growth and production of four new superior varieties of rice plants grown in the village Kadu Bale in Banjar sub-district pandeglang Regency of Banten Province. Research was conducted in the village Kadu Bale Banjar District Pandeglang in May until September 2010. The research used a randomized block design with new superior varieties as factor, which consisted of 4 levels with six replications. Parameters were observed: 1) The number of tillers (stems), 2) plant height (cm), 3) Age of panicle appear (HSS), 4) Age of harvest (days), 5) production per ha, and 6) The percentage of empty grains per clump (%). 7) The percentage of attacks Bacterial Leaf Light. The result showed that each variety (Ciherang, Inpari 1, Inpari 7, and Inpari 8 ) had potential interaction to abiotic and biotic environment during the period of its life (one season). Inpari 8 showed the best potential interactions of abiotic and biotic environment during the period of its life (one season).Keywords: rice, production potential, new superior varieties

ABSTRACTPalm juice as a raw material of brown sugar can be fermented easly. Smoke is used traditionally as an alternative indirect way to preserve the palm juice. Preservation of palm juice using liquid smoke directly have never been conducted before. The aim of this study is to investigate the effects of liquid smoke on palm juice preservation. First step, the liquid smoke was redestilated. Then, 0,50%, 1,00%, 1,50%, 2,00%, and 3,00%(v/v) concentration of liquid smoke was applied on palm juice when tapping and storage. It showed that the liquid smoke with concentration under 0,5% (v/v) cannot preserve the palm juice during 12 hours storage. 1% until 3% liquid smoke can preserve the palm juice during 12 hours storage. In fact, the pH of palm juice with liquid smoke increased when it was tapped, but the pH of palm juice without liquid smoke decreased certainly. The concentration of liquid smoke 1% and 3% could preserve the pH of palm juice above 6. That indicated the palm juice could be processed become brown sugar.Key Words: Liquid Smoke Palm Juice, Tapping, and Storage
