Abstract

ABSTRACTPhosphorus deficiency test research in several clones of sugar cane produced in seven months has been carried out during 25 April-25 November 2007 in the Laboratory ICBB, Nagrak Cilubang-Bogor. The purpose of this research is to influence the interaction between phosphoru concentration of sugarcane clones. This research using completely randomized design arranged as a factorial with two factors. The first factor is composed of sugarcane clones with three levels different there are: cv. Triton (V1), cv. PSJT 94-41 (V2), and cv. PA 175 (V3). The second factor is the addition of KH2PO4 in the culture medium modification of P deficiency consisting of six levels, namely: 0 mg/l KH2PO4 (D1), 34 mg/l KH2PO4 (D2); 68 mg /l KH2PO4 (D3); 102 mg /l KH2PO4 (D4); 136 mg /l KH2PO4 (D5) and 170 mg /l KH2PO4 (D6). Results obtained by the interaction between concentration of P given by clones tested in vitro, and sugarcane cv PA 175 best growth on media by providing 170 mg /l KH2PO4Key words: Saccharum officinarum L, phosphorus, devisiensi, in vitro

Abstract

Phosphorus in the soil is essential macronutrient for plant growth. Phosphate solubilizing bacteria are capable of managing phosphate availability in its soluble forms and are often found in the rhizosphere. This study aimed to know the level of total density and characteristics of phosphate solubilizing bacteria isolated from the rhizosphere of maize plants at three dry land locations in Banten.  The bacteria were isolated using serial plate dilution method. Results showed that four isolated phosphate solubilizing bacteria were obtained. Two isolates were obtained from Curug, one from Walantaka, and one from Petir. The total density of phosphate solubilizing bacterial colonies from those dry land locations were  1.9 x 1010 CFU/ml for Curug 1, 1.9 x 1012 CFU/ml for Curug 2, 6x1012 CFU/ml for Walantaka, and 4,8x1010 CFU/ml for Petir.

Abstract

ABSTRACTThe research was determine yield response of tomato plants (Lycopersicum esculentum Mill.) to the giving of several doses of banana stem compost and theconcentration of rice washing water. This research was conducted in Pasir villageBinangun Waringin Kurung Serang Banten, with used Randomized CompletelyBlock Design as factorial with three repetation. The factor were examined included the compost banana stem: 20 ton ha-1 (60 g polybag-1); 25 ton ha-1 (75 g polybag-1); 30 ton ha-1 (90 g polybag-1), and a dose of rice water, namely: rice water 500 ml+500 ml of water; 750 ml rice water+250 ml of water; 1000 ml rice water. Parameters observed include: number of fruits per plant, fruit diameter and fruit weight per plant. The results showed that the dose of 25 ton ha-1 (75 g polybag-1) compost banana stem gave the best effect to the parameters of number of fruits per plant (4.85 fruits), fruit diameter (2.88 cm), and fruit weight plant-1 (87.51 g ). Provision of rice washing water concentration of 1000 ml of rice washing water tend gave better effect to parameter number of fruit plant-1 (4.24 fruit), fruit diameter (2.87 cm), and fruit weight plant-1 (85.10 g). However Between the use of compost banana stems and rice washing water interactions do not occured on the yield of tomato (Lycopersicum esculentum Mill.).

Abstract

Fusarium is a phatogenic fungy that causes wilting in banana plants. One of alternative in controlling Fusarium oxysporum fungy is by using Botanical Pestiside on of them is talas beneng. This plants is local plants that grows wild around Karang Mountain, Pandeglang, Banten. A research to determine the effectiviness extract of talas beneng leaf (Xanthosoma undipes K.Koch) as fungy control Fusarium oxysporum in banana plants in vitro. The research used  randomized completely design with five treatments and five replication. The treatments is consisting of talas beneng leaf extract 0%, 5%, 5,5%, 6%, dan 6,5%. Observation was conducted after incubation for nine days at room temperature. The parameters observed was inhibition Fusarium oxysporum growth with indicated size of the diameter mycelium colony, inhibition percentage of mycelium and inhibits and thickness mycelium . The result of the talas beneng leaf extract showed that there was no difference in the concentration of the talas beneng leaf extract on the diameter of mycelium Fusarium oxysporum, but the extract of talas beneng leaf effective for inhibits and thickness myscelium density in mycelium fungi in vitro with concentration is 6%.

Abstract

ABSTRACTAnoectochilus formosanus is one species of Orchids, known as a “Jewel Orchids”and have been used as a folk medicine in China and Taiwan.The aim of this studywas to examine the response of using different types of explants and combination of growth regulators TDZ and BAP to morphogenesis of Anoectochilus formosanus Orchids by in vitro. The results showed that using different types of explants had very significant effect to the percentage of callus and shoot morphogenesis on 12 weeks after planting, the number of adventitious buds, adventitious shoot length, and callus diameter on three weeks until 12 weeks after planting. The best explant to callus morphogenesis was showing on shoot tip explant (50%) and to shoot morphogenesis was showing on auxillary buds and internode explant (100%). The best number of adventitious buds was observed in second internode explant with average number of shoots are 7.62 shoots. The best adventititous length was observed in axillary buds explant with average number of shoot length in 1.16 cm, and the best callus diameter was observed in shoot tip explant with average of diameter in 2.2 mm. The combination of plant growth regulator TDZ and BAP had a very significant effect to adventitious length on 10 weeks after planting, and a significant effect to adventitious length on 11 and 12 weeks after planting. The best adventitious length was observed on 0.25 mg L-1 TDZ + 0.75 mg L-1 BAP in 1.13 cm per explant on 12 weeks after planting. The best combination to callus and shoot morphogenesis was observed on 0.75 mg L-1 TDZ + 0.25 mg L-1 BAP. There was no interaction between used a different types of explant and combination plant growth regulator to morphogenesis Anoectochilus formosanus orchids by in vitro.

Abstract

This study aims to determine land suitability class for of plantation crops, namely; cocoa, arabica coffee and durian in Cemplang region, Ciomas district, Serang Regency. The research used several stages of research method including; collecting data and information, determining soil sample points and field surveys, taking soil samples and field observation, conducting laboratory analysis and assessing land suitability classes. Data processing was carried out using GIS through the ArcGIS application by overlaying and applying the matching method of land suitability parameters. The results showed that the assessment of land suitability at two sample points for cocoa plants was quite suitable (S2) with limiting factors for nutrient retention and erosion hazard, arabica coffee plants were not suitable (N) with temperature limiting factors, while the durian plants were by the marginal (S3) with the limiting factor of water availability. Efforts to improve the land can be made by making terracing, making drainage, applying agroforestry patterns, adding organic matter, liming and fertilizing.Keywords: land suitability, plantation crops, SIG
