| NOWADAYS, there is a call for the reduction of the environmental pollution resulted from over application of chemical fertilizers. Therefore, research has been done to investigate the possibility and efficiency of using bio fertilizers. This work was carried out at El-Mattana Agricultural Research Station (latitude of 25.17o N and longitude 32.33o E), Luxor Governorate, Upper Egypt during 2011-2012 season (plant cane crop) and 2012-2013 season (first ratoon crop) to study the effect of different levels of P- bio fertilizer (200, 400 and 600 g P- bio fertilizers /fad) on yield, yield components and quality of three sugarcane varieties (G.T.54-9, G.98-28 and G.99-103). P- bio fertilizer comprises an effective dissolvers strain of phosphate Bacillus megatherium var. Egyptiacum. Randomized complete block design with four replications arranged in split- plots system was used. The results indicated that the examined sugarcane varieties differed significantly. Promising varieties G.99-103 recorded the highest values of number of millable cane /m2, millable cane height, diameter and cane yield, while G.T. 54-9 surpassed in respect to Brix, sucrose , sugar recovery percentages and sugar yield in plant cane and its ratoon crops. Increasing P-bio fertilizer levels up to 600 g/fad significantly increased in number of millable cane /m2, millable cane height, diameter, Brix % sucrose%, sugar recovery%, cane and sugar yields in plant cane and its ratoon crops. It could be concluded that under the conditions of the present work, it is recommended to inoculate G.99-103 or G.T 54-9 sugarcane varieties cuttings by 600 g P-bio fertilizer/fad to produce the highest cane , sugar yield, as well as decrease the environmental pollution. | ||||
