Abstract

Soybeans become a source of plant protein and an essensial food ingredient in Indonesia. Extreme climate change causes weather changes; the impact is a long dry season which results in drought. Efforts to deal with drought stress are carried out using drought-tolerant soybean varieties that drop of production can be suppressed. The purpose of the study is to study growth responses for several different soybean varieties with drought-stricken conditions. The research was conducted from October 2019 to January 2020 at the Green House Agroecotechnology Laboratory of the Faculty of Agriculture, University of Sultan Ageng Tirtayasa, Banten. Factorial randomized block design method was then used which consists of two factors and three repetition. The first factor were that the Varieties consists of V1: Argo mulyo variety; V2: Deja 2 and V3 varieties: Dena varieties. The second factor was drought percentage comprising k1: 100% ATT (Groundwater Available); k2: 80% ATT, k3: 60% ATT and k4: 40% ATT. The results showed that differences in varieties and drought stress did not significantly affect the growth and yield of soybean crops. Argo Mulyo varieties are superior to drought stress compared to Deja 2 and Dena varieties from the weight of 100 seeds. No interaction of different soybeans varieties treatment and drought stress on all observation parameters.

Abstract

The Kasepuhan Cicarucub Indigenous farming system based on local wisdom, can play a role in the mechanism of meeting household food needs (Food Coping Strategy, the Indigenous People of Kasepuhan Cicarucub, Level I. in general, the food coping strategy at Stage I, namely 1) looking for other work, 2) changing food, 3) adding access to immediately get food, 4) doing changes in food distribution and frequency. Food Coping Strategy Kasepuhan Cicarucub Indigenous Peoples are at Level I, these conditions indicate that the mechanism of household survival in meeting food needs, including food security. Because the mechanism of food fulfillment at the household level of the Kasepuhan Cicarucub Indigenous Peoples does not take drastic steps, such as the mechanism of defending the behavior found in nerves II or III. The behavior of food coping strategy is done differently according to the problems faced by it. More and more households are taking drastic steps such as behavior at Levels II and III, showing a household that cannot stand food. This is due to a decrease in production, income to food consumption and nutritional status influenced by factors, such as.

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

This research was aimed to know effect of Physiological Character Response of Soybean Plants (Glycine max L.) on Waterlogging and Nitrogen Fertilizer. This research has been conducted from November 2019 until January 2020 at Green House Faculty of Agriculture, Sultan Ageng Tirtayasa University, Serang, Banten. This research used a Randomized Block Design with two factors, the first factor was waterlogging of four levels: 100% Soil Water Available (SWA), 125% SWA, 150% SWA, 175% SWA. The second factor was nitrogen fertilizer of three levels: 0 kg ha-1), 25 kg ha-1), 50 kg ha-1 with three replication. The results showed that treatment of waterlogging affects the number of soybean plant leaves at five Weeks After Planting (WAP). The number of leaves in the waterlogging treatment is 175% less compared to the waterlogging of 100% SWA, 125% SWA, and 150% SWA. Nitrogen treatment affects the stomata length of soybean crops. Nitrogen fertilizer doses of 50 kg ha-1 have a lower stomata length compared to doses of 0 kg ha-1 and 25 kg ha-1. There is interaction in the treatment of waterlogging and nitrogen fertilizers at a plant height of 2 WAP.

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
