Abstract
A B S T R A C T A field experiment was carried out during the two summer seasons of 2012 and 2013 at El- Areish Research Station, North Sinai Governorate, Egypt, (lat. 31.05 and long. 33.50) to study the effect of different rates of compost i.e. 0, 2 and 4 ton fed -1 combined with foliar application of ascorbic acid at different rates (0, 0.2, 0.4 and 0.6 g L -1 ) on growth, yield, its components and nutritional status of sunflower plants variety Sakha 1. Results could be summarized as follows: increasing the addition of compost up to 4 t fed -1 or ascorbic acid concentration up to 0.6 g L -1 increased significantly values of plant height, plant dry matter, chlorophyll A, B and A+B content at 90 days from planting as well as the head diameter, seed yield/ plant, 1000 seed weight and seed yield (t fed -1 ) of sunflower plant at harvest time 120 days from planting. Also, N, P, K and oil percentage of sunflower seeds with compared to control treatment (without addition of compost) in both seasons. Generally, the results in most cases, demonstrate that the all parameters increased significantly by using the high concentration of ascorbic acid 0.6 g L -1 combined with higher rates from compost 4 t fed -1 in both seasons.
