Effect of sowing date and intercropping pattern of sunflower with sugar cane on stalk-rot disease, productivity and quality [electronic resource].

One of the major problems in the Egyptian agricultural system is the severe shortage of edible oil production. Spring sugar cane area could provide a chance for farmers to use it for intercropping with oil crop such as sunflower in order to obtain additional income and help overcoming oil shortage. So_;:two field experiments were conduct at Mallawi Agric. Res. Station, El Minia-Egypt (latitude of 27.43° N & longitude of 30.50° E) during the seasons 2011/2012 and 2012/2013. The work aimed to study the effect of two intercropping dates (after cane harvest and after one month from the first date) and three cropping patterns of sunflower on the productivity and quality of cane and sugar yields in a split plot design. The obtained results could be summarized as follows: Seed yield/fed, of sunflower with sowing after cane harvest and remove crop waste was increased by 146.81 and 40.74% than sowing sunflower after one month from the first date in the two seasons, respectively. Sowing two rows of sunflower at 60 em on sugar cane recorded increases in seed yield (ton/fed) by 30.00 and 7.06% in the 1st season and by 8.51 and 6.25% in the 2nd season compared with sowing one row of sunflower at 30 em and sowing three rows of sunflower at 90 em. respectively. The minimum stalk-rot disease of sunflower was recorded at sowing sunflower.
