Effect of intercropping wheat with fodder beet under different levels of n- application on yield and quality [electronic resource].

Includes reference.

Two field trials were carried out at Sids Experimental Research Station, ARC, Beni Sueif Governorate through 2004/2005 and 2005/2006 seasons to study the effect of intercropping wheat with fodder beet under different N fertilizer rates on yield, yield components and chemical composition. The intercropping treatment was planting wheat on the back ridges 120 cm wide, in four rows (50 % of solid crop), while the treatments of N fertilizer were 70, 90, 110 and 130 kg NI fad. The treatments were assigned in randomized complete blocks design with three replications. The results indicated that the application of N significantly increased wheat grains yieldl fad. The increases in grains yieldl fad. were 9.91, 25.44 and 35.24 % for 90, 110 and 130 kg NI fad., compared with that of adding 70 kg NI fad. Roots yieldl fad. of fodder beet was significantly increased by increasing N fertilizer level. The increases in roots yield/fad. were 6.80,25.89 and 28.74 %, compared with that of adding 70 kg NI fad. Chemical compositions for fodder beet (crude protein, ash, total digestible nutrients and digestible crude protein) of fodder beet were significantly increased by increasing N fertilizer level, while crude fibers take an opposite trend. Intercropping fodder beet with wheat increased land eqUivalent ratio in the average of both seasons by 1.21,1.07,1.15 and 1.22%, when adding 70, 90. 110 and 130 kg N fertilizer/fad., respectively. The total income was calculated by L.E 4063.81, 5838.00, 6542.50 and 6838.80 for 70, 90, 110 and 130 kg NI fad., respectively. The highest return between growing fodder beet as sole crop and its growing with wheat was collected when adding 130 kg NI fad (2718.80 L.E.).
