Abstract

Sunflower response to four cropping systems and 30 (N1), 45 (N2) and 60 (N3) kg N/fed. were studied at Agriculture Research Station, Alexandria University, Egypt, during 2013 and  2014 summer seasons. Cropping systems were sunflower relay-cropping into (Sun1) or double cropping with faba bean (Sun2), in addition to sunflower double cropping following fodder (Sun3) and silage (Sun4) maize crops. Responses of head and 100-seed weights, as well as seed yield/ fed and harvest index (HI) to cropping systems, were significant over the two seasons. The highest values of those traits were obtained from relay-cropped sunflower to faba bean (Sun1), however, the lowest values resulted from sunflower sowing after silage maize (Sun4), that was previously relay-cropped into faba bean. Differences in seed yield and HI, for the combined treatments, were significant, as indicated by crop systems*N levels interaction in both seasons. The highest values of the two traits were obtained from (Sun 1) at 45 kg N /fed, whereas, the least values resulted from (Sun4) at 15 kg N/fed. increasing the nitrogen level from 30 to 60 kg/ fed led to significant increases in plant height, head seed weight, seed yield/ fed and harvest index in both seasons. Response of head –seed and 100-seed weight, in addition to seed yield /fed. of sunflower, as N level was applied up to 45 kg N/fed. to nitrogen fertilization, was linear. Sunflower relay-cropping and growing of short season crops should be applied to enable farmers to plant more than two crops per year.
