Wheat Productivity as Affected by Different Fertilization Regimes

Abstract

T HIS STUDY was conducted to determine the effect of balanced fertilization based on soil test for wheat plant grown in sandy soil. Two experiments were conducted during the seasons 2009/2010 and 2010/2011 at the research station of the Agricultural Research Center - Ismailia Governorate, Egypt. The design was randomized complete block with four replications and included seven treatments include control (T 0 ), farmers fertilization (T 1 ), recommended by Ministry of Agriculture MoA (T 2 , T 3 and T 4 ), based on soil test (T 5 ) and (T 6 ) based on soil test plus micronutrients. The results in this study indicated that all NPK treatments had a positive effect on all parameters tested compared to control (no addition of fertilizers). The positive effects of the treatment are estimated in descending order: NPK by soil test +MN ( T 6 ) ˃ NPK by soil test ( T 5 )˃ NPK MoA ( T 2 )˃ fertilization by Farmers ( T 1 ) NK MoA ( T 4 )˃ NP MoA ( T 3 )˃ control ( T 0 ).NPK, depending on soil test plus foliar micronutrient (balanced fertilization) had also been shown to significantly increase plant nutritional status, grain yield, yield components and nutritional value of grain and straw. The highest values of nutrient were achieved by the balanced fertilization treatment NPK by soil test +MN ( T 6 ) which were in the first season (116:41:55) and the second (122:45:65) N, P 2 O 5 and K 2 O, respectively. in combination with two times foliar feeding with chelated micronutrient compound).
