Abstract

ABSTRACTThe objective of this experiment were find out responses various local peanut cultivars of Pandeglang to soil water availability decline condition. Randomized complete block design with three replications was used in this experiment. First factor is level of soil water availability consisted of three levels (100%, 75%, and 50%). Second factor is local cultivar of Pandeglang consisted of four levels(local cultivar of Menes, of Cibaliung, of Malingping, and of Cikeusik). Result of research indicates that decline soil water availability results degradation of number of root nodules and seed wight per plant for all local cultivar peanut of Pandeglang. Degradation of soil water availability out of 100% becomes 75%to result degradation of number of root nodules per plant average of 24,59% and degradation of soil water availability out of 100% becomes 50% to result degradation of number of root nodules 31,15%. Degradation of soil water availability out of 75% becomes 50% doesnt show degradation of number ofroot nodules manifestly. Degradation of soil water availability out of 100% becomes 75% to result degradation of seed wight average of 10,77% and degradation of soil water availability out of 100% becomes 50% to result degradation of seed wight 22,08%. Degradation of soil water availability out of75% becomes 50% doesnt show degradation of seed wight manifestly.Key words: local cultivar, peanut, root nodule, soil water availability

Abstract

The experiments were conducted to determine soybean growth and yield responses to various ways of placement and dose of urea fertilizer. Experiments using a randomized block design factorial, with four replications. The first factor is the ways of placement of urea consists of two levels, namely: be placed next to the planting hole and placed along the bolt in between the rows of plants. The second factor is the dose of urea fertilizer consists of four levels, namely: 50 kg ha-1, 100 kg ha-1, 150 kg ha-1, and 200 kg ha-1. The results showed that the growth of soybean (plant height and number of leaves) showed no differences due to different ways of placement urea but soybean yield components and the yield showed differences due to different ways of placement of urea. Yield components (pod number, pod dry weight, and number of seeds) and yield (seed dry weight) of soybean is higher when the ways of placement of urea along the bolt is placed in between rows of plants compared with plants placed on the side. Differences urea dose given either 50 kg ha-1, 100 kg ha-1, 150 kg ha-1, and 200 kg ha-1 showed no difference on the growth and yield of soybean plants.Key words: doses, fertilizers placement, soybean, urea

Abstract

The objective of the research was to determine the effectiveness of botanical pesticides Galangal rhizome, Lemongrass, and Babadotan leaves solvent on mosquito bugs (Helopeltis sp) of Cocoa crop (Theobroma cacao L.). The research was conducted from July to August 2013 on cocoa farms at Luarang Sukalaba Village, Gunungsari District, Serang Regency of Banten Province. The research used a randomized block design (RBD) with one factor that consists of 4 treatments, ie P0 = Control, PL = Galangal Rhizome 100 gr/l, PB = Babadotan Leaves 100 gr/l, PS = Leaves Lemongrass100 gr/l and these were repeated four times. The parameters observed were widespread attack, intensity of pest attacks and Helopeltis sp population. The results showed that application of Galangal Rhizome solvent could suppress extensive solution and intensity of Helopeltis pest attacks. The application of lemongrass leaves solvent solution could suppress the pest population, where as babadotan leaves act as an attractant against Helopeltis sp. in cocoa.Key Words: Botanical pestisides, Insect pest, Galangal rhizome, Lemongrass, and Babadotan

Abstract

Experiments were performed to characterize the response of peanut local cultivars from Banten to soil water availability decreased during the reproductive phase. The experiments used factorial randomized block design with three replications of two factors. The first factor was the soil water availability consists of three levels (100%, 75%, and 50%). The second factor was the peanut local cultivars from Banten consists of four levels (local cultivars of Cikeusal, Petir, Anyer, and Cisoka).  The results showed a similar general pattern that was the decreasing soil water availability resulting in the decreasing amount of flowers and pod number of peanut local cultivars from Banten.  Flowers appear began to plant at 24 and ending at 46 days after planting with a period of at most appear at the age of 26 up to 36 DAP.  Four peanut local cultivars from Banten showed no difference in tolerance to the declining of soil water availability.  Number of flowers and peanut pods begin to decrease when soil water availability as as much as 75%. Keywords: Flower, Local cultivars, Peanuts, Soil water availability, Pod number

Abstract

The research was aimed to determine the response of root-shoot ratio of melon (Cucumis melo L.) on planting medium and different water availability. The research was conducted for three months starting from July until September 2017 at Greenhouse of Agriculture and Marine of Cilegon City. The experimental used Randomized Completely Design as factorial with 2 factors. The first factor was planting medium consisted of 3 levels ie 100 % soil medium, compost medium 100%, and soil medium + compost 1: 1. The second factor was water stress consisted of 4 levels ie without water stress, water stress interval every 3 days, water stress interval every 6 days, and water stress interval 9 days. The results showed that the root-shoot ratio was influenced by reduced water availability and medium planting. The longer the water delivery interval decreased the root-shoot ratio of melon.Keywords: Root-shoot ratio, Planting medium, Water deficit

Abstract

The research was conducted to know the effect of different doses of nitrogen fertilizer on the land without and with weeding. The experiments used Randomized Completely Block Design as Factorial was conducted at Sitandu Curug Serang. The result showed that the difference of dosage of N fertilizer up to 100 kg Urea ha-1 did not show the difference of green bean plant yield. Weeding once a week could increase the yield and the components of green beans about 78.3% both the number of pods per plant and the weight of seeds per plant.Keywords: Green bean, Nitrogen, Weeding
