Abstract

Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore, during kharif 2007 and 2008 to study the effect of sulphur and boron fertilization on yield attributes and yield of soybean. The experiment was laid out in a factorial combination of S and B following factorial randomized block design replicated thrice. There were 25 treatment combinations consisting of five rates of both S (0, 10, 20, 30 and 40 kg S ha-1) and B (0, 0.5, 1.0, 2.0 and 4.0 Kg B ha-1). The results of the experiments revealed that application of 30 kg S ha-1 recorded better yield attributes viz., branches plant-1, pods plant-1, seeds pod-1 and 100 seed weight and higher yield than the other treatments. Similarly, application of boron 1.0 kg ha-1 recorded better yield attributes and higher yield of grain and straw.
