Abstract

High soil acidity is one of the problems caused low groundnut productivity on South Kalimantan. Using adaptive variety is one effort for increasing yield. The objective of this research was to determine the yield performance and tolerance of groundnut to soil acidity on swamp areas. This research was conducted on acid sulphate soil at Jajangkit Timur-Batola-South Kalimantan on wet season of 2003/04 and on swamp area at Setiap-Pandawan-Hulu Sungai Tengah-South Kalimantan on dry season of 2003. This research was arranged in Randomized Complete Block Design with three replications. Twelve genotypes and 3 check varieties i.e. Jerapah, Singa and Lokal variety, were tested on those regions.The result showed that some groundnut promising lines had good performance on acid sulphate soil and swamp areas. Performance of yield and its component  were influenced by soil environment, i.e. soil acidity, Ca content and Al saturated. The best five promising lines on acid sulphate soil were GH-3, GH-4, GH-5, GH-8 and GH-9, while on swamp area were GH-2, GH-5, GH-6, GH-9 and GH-11. Two promising lines, i.e. GH-5 and GH-9, performed better on both areas.   Key words: Performance, groundnut, swamp areas

Abstract

The aims of this experiment were to evaluate the effect of rock phosphate application and combination phosphate- solubilizing bacteria and farm yard manure on soil available P and growth of soybean on Ultisol from Kentrong village, Banten province. Factorial experiment design with two factors was used in randomized complete block design ; with three replications. The first factor was rock phosphate i.e. : 0, 30, 60, and 90 kg Plha, and the second factor was ' combination of phosphate solubilizing bacteria (PSB) and farm yard manure (FYM) i.e. : without PSB and FYM (control), PSB (Pseudomonas fluorescens), FYM 10 t/ha, and PSB+FYM Results indicated that significant positive effect of rock phosphate and combination of PSB and FYM application occurred on soil available P, number and dry weight of nodule, dry weight of root and shoot. Rock phosphate application with rates of 30, 60, 90 kg P/ha increased soil available P 247%, 356% and 592% respectively compared 'to without P. Phosphate-solubilizing bacteria, farm yard manure and PSB+FYM increased 27%, 30% and 48% respectively compared to control. Phosphate-solubilizing bacteria and farm yard manure combination with phosphate rock 30 kg P/ha dosage increased dry weight of soybean shoot 29% compared to control. Key words: Rock phosphate, Phosphate-solubilizing bacteria, Farm yard manure; Soybean, Ultisols.
