Sulphur and boron have been found to act in a synergistic manner for enhancing the yield and quality of sesame (Sesamum indicum L.). As it is the choice crop of farmers in the summer rice fallows of Onattukara, field experiments were laid out in factorial RBD with four levels each of sulphur and boron with the variety Thilarani. The levels of sulphur tried were 0 kg S ha-1, 7.5 kg S ha-1, 15.0 kg S ha-1 and 30.0 kg S ha-1 and 0 kg B ha-1, 2.5 kg B ha-1, 5.0 kg B ha-1 and 0, 2.5, 5.0 and 7.5 kg B ha-1 for boron which were applied as gypsum and borax, respectively. The incubation study, designed to understand the release pattern of nutrients reveled that highest quantity of sulphur and boron were available during the 30th day of incubation and there after showed a decreasing trend. Application of sulphur @ 30 kg ha-1 and boron @ 7.5 kg ha-1 improved the available nutrient status of Onattukara soil. The nutrient use efficiency of sulphur was highest at 30 kg ha-1 and that for boron it was 2.5 kg ha-1. It also registered a significant positive impact on enhancing the yield and yield attributes of sesame in such a way that the highest rates of both the nutrients registered maximum yield from the crop in both the years.

Abstract


Sulphur and boron have been found to act in a synergistic manner for enhancing the yield and quality of sesame (Sesamum indicum L.). As it is the choice crop of farmers in the summer rice fallows of Onattukara, field experiments were laid out in factorial RBD with four levels each of sulphur and boron with the variety Thilarani. The levels of sulphur tried were 0 kg S ha-1, 7.5 kg S ha-1, 15.0 kg S ha-1 and 30.0 kg S ha-1 and 0 kg B ha-1, 2.5 kg B ha-1, 5.0 kg B ha-1 and 0, 2.5, 5.0 and 7.5 kg B ha-1 for boron which were applied as gypsum and borax, respectively. The incubation study, designed to understand the release pattern of nutrients reveled that highest quantity of sulphur and boron were available during the 30th day of incubation and there after showed a decreasing trend. Application of sulphur @ 30 kg ha-1 and boron @ 7.5 kg ha-1 improved the available nutrient status of Onattukara soil. The nutrient use efficiency of sulphur was highest at 30 kg ha-1 and that for boron it was 2.5 kg ha-1. It also registered a significant positive impact on enhancing the yield and yield attributes of sesame in such a way that the highest rates of both the nutrients registered maximum yield from the crop in both the years.
