Abstract
Field experiments were conducted during the 2008 rainy season and 2009 dry season at the Faculty of Agriculture Farm, Bayero University, Kano, Nigeria (11° 58' N and 8° 25' E). The experiment investigated the response of three varieties viz: SAMNUT 21, SAMNUT 22 and SAMNUT 23 and five levels of gibberellic acid viz: 0, 100, 200, 300 and 400 mg L-1) foliar applied at 3 and 6 weeks after sowing on yield and yield traits of groundnut. The 15 treatment combinations were laid out in a randomized complete block design and replicated four times. The results obtained showed that 200 mg L-1of gibberellic acid level significantly (P<0.01) reduced days of first flowering and 50% flowering. The highest pod, kernel and haulm yields was obtained at 100 mg L-1 levels of gibberellic acid during wet and dry seasons. SAMNUT 23 had the highest pod, kernel and the haulm yields also across seasons. There were no significant interactions between gibberellic acid concentrations and the varieties in all the traits evaluated. Regression analysis however, pointed out that 172.7 and 161.4 mg L-1 gibberellic concentrations during the wet and dry seasons respectively are the optimum levels required in enhancing growth and yield in groundnuts. Further studies with respect to the best performance of varieties during growing seasons under the influence of gibberellic acid to be ascertain in a further research
