Abstract
This study was conducted during the seasons 1993/94 and 1994/95 at the Demonstration Farm of the Faculty of Agriculture, University of Khartoum to investigate the effect of different levels phosphorous fertilizer, two solving methods and two cultivars on growth, forage yield, forage quality and seed production of alfalfa. Three levels of Phosphorous were applied (0, 50, 100 Kg P2O5/ha) in form of triple superphosphate (48 % P2O5). The sowing methods were sowing on flat versus sowing on ridge. The cultivars used were the local, Hegazi and the introduced Pioneer 5929). Phosphorous application increased plant height, plant density, fresh weight, dry weight, leaf to stem ratio, seed yield components, final seed yield of alfalfa and improved forage quality in term of crude protein. Sowing alfalfa on ridges increased plant density during the sampling occasions before harvest. However, at all harvesting dates sowing on flat gave higher plant and consequently improved forage fresh weight and dry weight. At all sampling occasions, plant height was higher on ridge due to the reduction in plant population. Sowing the crop on ridge was found to improve seed yield components and final seed yield. The local cultivar, Hegazi was found to be superior over the introduced cultivar, Pioneer 5929 in plant height, fresh weight, and dry weight, while Pioneer 5929 was superior to the cultivar Hegazi, in plant density, leaf to stem ratio, forage quality, most of the seed yield compoonents, and final seed yield.
