Abstract
The current study was conducted to assess the main and interaction effects of humic acid with different levels of phosphate fertilizer on growth of grain sorghum {Sorghum bicolor (L) Moench} grown in calcareous soil. two field experiments were carried out consecutively at tamiya experiment station Agric. Res. center (A.R.C ), Fayoum Governorate Egypt, during the during the summer growing seasons 2019 and 2020. The experimental layout was a split- split plot arranged in randomized complete block design with four replications. At the vegetative growth results displayed that application of phosphorus fertilizers had a significant effect in all growth parameters plant height, stem diameter, number of green and dry leaves plant-1 and flag leaf area plant-1, plant weight. Soil application and Foliar spraying of humic acid reflected positive significant influences on growth parameters in both seasons. Soil application H20 followed by H10 and Foliar spraying F2 followed by F1 were the potent treatment for increasing growth parameters compared with control treatments (without humic acid).
