REPRODUCTIVE DEVELOPMENT AND NUTRITIONAL ATTRIBUTES OF GROUNDNUT AS INFLUENCED BY BORON AND LIGHT
MD. QUAMRUZZAMAN
Abstract
Boron application at proper concentration and providing adequate light is necessary to improve the reproductive development of crops. Therefore, a field experiment was conducted to study the effects of boron and light at planting to evaluate their effect on the reproductive development and mineral elements of two groundnut cultivars. Treatments comprised two groundnut cultivars, viz., ‘Dhaka-1 (C1)’ and ‘BARI Chinabadam-8 (C2)’; three levels of boron (B), viz., 0-kg B ha-1 (B0), 1-kg B ha-1 (B1) and 2-kg B ha-1 (B2); and two levels of light, viz., normal daylight (≈12-h light) and normal daylight + 6-h extended red light at night (≈18-h light). Results revealed that the reproductive characters, yield, shelling percentage and mineral elements were markedly increased for B application and for ‘BARI Chinabadam-8’. All of the reproductive units and mineral elements were increased for imposition of light but decreased the number of pods and pod yield. Thus, reproductive development can be improved by application of boron but not for under extended light and mineral elements can be improved by both light and boron.
