The experiment therefore consisted of 12\ntreatments with three replicates, and plots were completely randomized. Growth\nand P uptake were followed on complete selected plants 56 and 101 days from\nsowing, corresponding to VT and V6 of maize phonological stages. At harvest\n(after 101 days), productivity of grain yield and straw were measured and some\nefficiency parameters related to growth. Also, P uptake and productivity were\ncalculated. Maize plants produced the highest dry matter in non-humic treatments\nat VT stage in the treatment P5H0 (115.1g\/plant), which was not significantly\ndifferent compared to the second TSP application rate in the presence of humate\n(treatment P2H1=112 g\/plant). The analysis of variance showed a highly\nsignificant effect for both phosphate and humates applications on relative\ngrain yield increase (RGYI), which increased in P3H0 treatment by 21.5% and in\nP3H1 treatment by 28.1%. Humate application did not provide a significant\nimpact on the phosphate utilization efficiency.<\/p>\n\n\n\n<p><strong>Keyword: <\/strong>Phosphate fertilizer TSP, Potassium humate, <em>Zea mays,<\/em> Calcareous soil.<\/p>\n\n\n\n<p>Full paper in Arabic: <a href=\"http:\/\/agri-research-journal.net\/sjar\/wp-content\/uploads\/2020\/06\/v7n3p27.pdf\">PDF<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Osama Hatta(1) Ghiath Alloush*(2) and Rabee Zainah(1) (1).
