Abstract

Field experiments were conducted during the summer (February-May) and south west monsoon (June-September) seasons of 1996 and 1997 at the Aliyarnagar Agricultural Research Station of Tamil Nadu Agricultural University, India, to study the growth and yield of soybean in response to irrigation, composted coir pith, time of N, P, K application and use of a nutrient mixture spray. The results revealed that irrigation at 0.90 IW/CPE [ratio of Irrigation Water Depth (IW) to Cumulative Pan Evaporation (CPE)], the application of composted coir pith and the split application of N, P and K in conjunction with a nutrient mixture spray significantly increased the plant height, leaf area index, dry matter production and grain yield of soybean. However, the root length of soybean was significantly reduced by irrigating at 0.90 IW/CPE (compared to irrigation at 0.70 IW/CPE and 0.50 IW/CPE) and by the application of composted coir pith.

8 of 10 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
