Abstract

Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. By keeping the water-table constantly, soybean will be avoided from negative effect of inundation on soybean growth because soybean will acclimatize and improve its growth. The objective of the research was to study the response of soybean varieties under saturated soil culture on tidal swamps. The research was conducted at Banyu Urip of  Tanjung Lago Sub District, Banyuasin District, South Sumatera Province, Indonesia from April to August 2009. The experiment was arranged in a split plot design with three replications. The main plot was water depth in the furrow consisted of without watering, 10, 20, 30, 40 cm under soil surface (uss). The subplot was soybean variety consisted of Tanggamus, Slamet, Willis, and Anjasmoro. The result showed that the interaction between varieties and water depth significantly affected growth and seed production, except pod numbers/plant. The values of all variables were higher under SSC compared to those cultivated without watering (control), but varieties responded to SSC differently. The highest seed production was obtained from Tanggamus with 40 cm uss, i.e. 4.83 ton/ha but it was not significantly different from those at water depth 20 (4.63 ton/ha) and 30 cm uss (4.71 ton/ha). However, technically and economically, 20 cm uss was the most appropriate water depth for soybean production on tidal swamps.   Key words: Glycine max L. (Merr.), water management, water table

Abstract

A study to explore the agronomic response of some soybean genotypes to temporary flooding in the type-B overflow tidal swamp and to obtain the adaptive genotype to the environment was arranged in a split-plot design at coordinates 2°64’46.77” S and 104°75’27.75” E with an altitude of 3.5 m above sea level. The main plot was subject to short-term flooding with a variety of cultivation technologies consisting of saturated soil culture (SSC) for one month without flooding, SSC for one month with flooding, SSC during plant growth without flooding, SSC during plant growth with flooding and non-SSC/dry cultivation. The subplot was soybean genotype consisting of 6 genotypes: Tanggamus, Karasumame (Naihou), M652, Anjasmoro, M100-47-52-13, and Tachinagaha. The result showed that impaired soybean growth at the beginning of the growth stage caused pressure on the later growth stage and decreased soybean yield. Short-term flooding reduced the soybean yield. The non-tropical genotypes of Karasumamae (Naihou), M652 and Tachinagaha produced the lowest yield of seeds; 20% lower than the tropical genotypes of Anjasmoro, M100-47-52-13 and Tanggamus with SSC during plant growth without flooding treatment. The Karasumame (Naihou) genotype produced the highest seed yield of the three non-tropical genotypes. Anjasmoro and M100-47-52-13 produced the highest seed yield at temporary flooding.

Abstract

Many peanut planting fields have limited water resources, therefore farmers must use water efficiently. A study aimed to obtain appropriate watering intervals and adaptive peanut cultivars at limited water conditions. The greenhouse study was conducted at Central Bengkulu Regency, Indonesia, from December 2019 to March 2020. Three varieties of peanut (Takar 2, Talam 1, and Kancil) and four watering intervals (1, 3, 6, and 9-day intervals) were arranged using a split-plot design and replicated three times. Results showed that the three varieties evaluated had similar agronomic performance (P≥0.05). The Takar 2 and Kancil had similar growth and yield components to the dry land adaptive variety Talam 1. It indicates that Takar 2 and Kancil cultivars are suitable for cultivation in a water-limited field. Watering every 6 days reduced peanut growth and insignificantly differed from watering every 9 days. Daily watering produced the highest growth and yield of peanut, irrespective of genotypes. Nevertheless, in areas with limited water availability, watering every 3 days was sufficient with yield reduction by about 25.55% of watering daily. Keywords: drought, irrigation, peanut production
