Abstract
This experiment comprises a Laboratory and field trials at Horticulture Research station, Mansoura and Shabrawish Village, Aga, Dakahila Governorate, Egypt during the winter seasons of 2020/21 and 2021/22 on carrot to investigate the effect of seed priming and foliar application with some stimulants on growth, yield and quality of carrot. In the experiment dry seed (control), distilled water, salicylic acid (SA) at a rate of 50 ppm, ascorbic acid (AsA)100 ppm, chitosan (Chit.) 0.5 %, Zinc sulphate (ZnSO4 .7H2O) 2% and hydrogen peroxide (H2O2) 1% were tested as seed priming for 24 (hr.). In addition, the same stimulants were tested as foliar application in the same concentration in priming whereas (Chit.) was applied at 200 ppm, ZnSO4 at 200 ppm and (H2O2) at 100 ppm spraying was done thrice at 35, 50 and 65 days after sowing date. In the Laboratory trail all priming treatments significantly increased seed germination parameters of carrot ZnSO4 being the most effective treatment for (germination %, weight of 100 seedling, seedling length and seedling vigor index) while the least seed germination time was recorded in response to (chit.). Results of the field trial indicated that vegetative growth parameters, yield and its component root quality, NPK content in leaves, chlorophyll a, b and total chlorophylls were significantly increased due to seed priming in ZnSO4 in both seasons. The highest NPK in roots were obtained due to foliar spraying with (H2O2) however, the highest value of Zn in root was recorded in response to foliar spraying ZnSO4.
