Abstract (AB)Poor dry bean yields have been frequently observed in variety trials on research stations in Mauritius. Since there was no obvious cause, trials were conducted in 1990 and 1991 to assess the effects on yields of nematodes; the macronutrients, N, P, and K; the minor nutrients S and Ca; the micronutrients, B and Mo; and organic matter (OM). In three trials in 1990, no responses were observed to B and carbofuran, eliminating B deficiency and nematodes as causes of the poor yields. The addition of OM in the form of sugar cane factory scums improved yields. Greater levels of NPK than the recommended 46 kg N, 73 kg P2O5 and 70 kg K2O per ha had little effect on yields, suggesting that macronutrient levels were adequate. In two trials in 1991, neither Ca applied as lime nor elemental S applied at sowing had any effect, though there was a slight positive effect of Mo. The adequacy of recommended levels of N, P and K and the positive effects of organic matter in the form of farmyard manure (FYM) or factory scums were confirmed. On-farm trials on seed quality, the effects of green manure and the control of root rots are required before issuing recommendations on how to achieve consistently good bean yields.
