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

ABSTRACTThe toxicity of Al, Fe, and Mn is highly determined by the shape of the metalfractions. Therefore, the specific forms of Al, Fe, and Mn inside the soil are veryimportant to know because they are related to soil fertility. The purpose of this study was to determine the distribution of the Al fraction on the acid soil profile of dry land in Lebak Regency, Banten Province. This research was conducted from April to June 2019 in Maja District, Lebak Regency, Banten. The research was descriptive explorative with intentional sampling for special purposive sampling. The soil was tested with a main parameter using single extraction for Al Fractionation. The results showed that the Al fraction in amorphous form (Al-o) was more dominant than Al in dissolved form (Al-dd) in all horizon layers (0-120 cm). Moreover, the Al fraction in organic amorphous form (Al-p) was also more dominant than Al in the inorganic amorphous form (Al-po) at horizon layer of 0-15 cm, while at horizon laeyer of 15-120 cm the Al-po form was higher than Al-p. Al fraction in the form of organic amorphous had higher bond compared with Al form of organic amorphous in the soil layer of 0-120 cm.
