| Popis: | There is a dearth of information on the effective irradiation dose for inducing variability in groundnut genotypes. A screen house experiment was conducted at the Department of Soil Science, Ahmadu Bello University, Zaria (ABU). It was to investigate the effect of induced genetic variability (by neutron irradiation) and four phosphorus rates (0, 20, 40 and 60 kg P 2 O 5 ha -1 ) on the performance of some groundnut [(Arachis hypogaea (L.)] genotypes grown on a P-deficient Alfisols at Samaru, Zaria. A fraction of each of the two genotypes (SAMNUT 24 and SAMNUT 26) was irradiated, in a 5-Curie Americium-Beryllium (Am-Be) isotope neutron source, having a thermal neutron flux of 2.7387 x 10 4 n cm -2 sec -1 for six days, at the Centre for Energy Research and Training, ABU. The irradiated (G 1A and G 2A ) and nonradiated (G 1B and G 2B ) seeds; and the P rates were laid out in a randomised complete block design (RCBD), in a screen house, and replicated thrice. Data collected during the study included; plant height, numbers of branches, flowers, nodules, leaves and chlorophyll content (CC). Both G 1A and G 2A significantly (P |
