Abstract

Iron (Fe) toxicity is a major constraint in rice production that decreases yield due to high level of soluble Fe. The aims of this experiement were to study the effect of particular Fe concentrations in nutrient solution on rice growth, and to determine Fe concentration in nutrient solution that caused light, moderate, and severe Fe toxiciy symptom. The experiment was conducted in a greenhouse, Bogor Agricultural University from May to July 2010. A randomized block design with two factors and three replications were used in this study. The first factor was Fe concentration in the medium solution (2, 50, 100, 200, 400, 600 ppm Fe), and second factor was rice genotypes (IR64, Margasari). The results showed the higher Fe concentration in the solution resulted in higher scores of iron toxicity symptoms, higher Fe levels in the plant, and caused stunted growth of rice plants. Levels of Fe in a solution of ≥ 200 ppm Fe inhibited plant growth. Iron toxicity symptom in Margasari was lower than the IR64 varieties, especially at concentrations of 200 and 400 ppm. According to the regression equation Y = 0.022X+ 1849, Fe concentration in the solution which caused light Fe toxicity symptom (score ≤ 3) was ≤ 52 ppm Fe, moderate (score = 5) was 143 ppm Fe, heavy (score = 7) was 234 ppm Fe, and severe (score ≥ 9) was ≥ 325 ppm Fe. Keywords: iron toxicity symptoms, iron concentration, rice

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.
