| Abstract | ||||
| An intercropping trail of wheat with sugar beet was carried out at Gemmeza Research Station, El Gharbiua Governorate,Egypt, in2009/10 and 2010/11 seasons to study the effect of intercropping wheat with sugar beet at different sowing dates. 1-Results showed that all the traits of sugar beet were significantly reduced by intercropping system of wheat with sugar beet as compared with pure stand in both seasons.Intercropping system of wheat with sugar beet on the top of the second bed (120cm)S4 had the highest values for all character. ,while,the lowest values were obtained from intercropping wheat with sugar beet on the other side of the second ridge (60cm S1). 2- All characters for yield and yield components of wheat were significantly affected by intercropping system and sowing date in the two seasons,except,spike length in the first season and No. of spikelets in the second season,respectivily.The highest values were obtained from intercropping wheat with sugar beet on S3 in both seasons,while,from S1 on sowing date (T1) in the both seasons . 3-Table(1) The interactions between intercropping system and sowing dates of wheat had significant effects on all the traits of sugar beet ,except,yield(t/fed.) in both seasons,while,all charactersof wheat had in insignificant in both seasons,except, plant height, no.of spikes/m2,No. of grains/spike and grain yield/fed.were had significant effects in both seasons. 4- The highest values of land equivalent ratio( LER) was1.306and1.253 in the of first and second seasons,respectively. 5-Relative crowding coefficient(R.C.C.)was12.99 and 5.36 in the two seasons,were recorded with intercropping wheat on the top of the second bed of sugar beet (S4) . 6-Aggressivity(Ag) indicated that sugar beet was the dominat crop,whereas wheat was the dominated in both seasons. 7- The highest gross return was obtained with cropping 25% of pure stand of wheat on the top of the second bed of sugar beet (S4) in the first season,while,the highest value was produced when wheat sown on all beds of sugar beet in the second season(S3). From this study it could be concluded that, the best results for sugar beet was obtained by intercropping system of wheat with sugar beet on the top of the second bed(120cm)S4with sowing wheat after42 days(T3).While,the highest grain yield/fed for wheat was obtained with suger beet planted on both sides of the bed(120cm) and wheat planted on the top of all bedsxwheat planted in the same time of seeding sugar beet (S3/T1)in both seasons. | ||||
