Title
Phosphorus Role on Growth, Yield and Quality of Grain Amaranth: Grain amaranth (Amaranthus cruentus L.),Used
Delivery time: 8-12 business days (International)
Knowledge of P uptake, utilization and requirements of improved grain amaranth varieties are lacking while the high cost of conventional phosphorus fertilizers limits their use by resourcepoor farmers resulting in increased interest in lowcost rock phosphates (RPs) as alternative P sources for grain amaranth production. The study was therefore conducted on the horticultural experimental farm at Ibadan, Nigeria (730N, 3054E, 168m a.s.l.). The study was conducted to: (1) determine the optimum P rate for grain amaranth and (2) evaluate P sources and their residual effects under three consecutive croppings of grain amaranth in the screenhouse and under field conditions for grain amaranth production. It was concluded that since ORP and SRP are as efficient as SSP, they could be used as an alternative low cost P sources in grain amaranth production. They are therefore recommended to be applied at every second cropping of amaranth under continuous cropping.
