Finger millet (Eleusine coracana L.) grain yield and yield components as influenced by phosphorus application and variety in Western Kenya uri icon

abstract

  • Finger millet is one of the potential cereal crops that can contribute to the efforts ofrealization of food security in the Sub-Saharan Africa. However, scientific information availablewith regards to improving soil phosphorus supply and identification of P efficient varieties for thecrops potential yield is limited. In order to investigate the effects of P levels on yield componentsand grain yield On-station field experiments were conducted in two sites of western Kenya duringthe long and short rain seasons of 2015. The experiment was laid out in a Randomized CompleteBlock Design in factorial arrangement with four levels of P (0, 12.5, 25 and 37.5 kg P2O5 ha-1 andthree finger millet varieties (U-15, P-224 and a local check-Ikhulule) and the treatments replicatedthree times. The increase of phosphorus levels significantly (P?0.05) increased the grain yieldover the control up to 25 kg P2O5 ha-1 during the long rain seasons and 25 kg P2O5 ha-1 during theshort rain seasons in both sites. Interactions at P?0.05 were revealed on the grain yield whereimproved variety P-224 at 25 kg P2O5 ha-1 produced the highest grain yield of 4.74 t.ha-1 in Alupeand 4.77 t.ha-1 in Kakamega and the consistent results suggest that the combination is highlyrecommended. Therefore the use of judicious and proper rates of P fertilizers can markedlyincrease the grain yield of finger millet in western Kenya
