FIELD experiment was conducted at Sakha Agric. Res. Station, Kafer EL-Sheikh Governorate, Egypt during 2013/2014 and 2014/2015 seasons to study the relative advantage of intercropping faba bean (variety Giza 643) with sugar beet (variety Geloria) and its impact on yield and quality attributes of both crops. A split plot design with three replications was used. The treatments of faba bean sowing distance (10, 20 and 30 cm) allocated in the main plots, while, the ten combination of nitrogen levels with bio fertilizers (90, 72, 54, 36 kg N/fad, 72, 54, 36 kg N/fad + Cerealine, 72, 54, 36 kg N/fad + Rizobacterine) were arranged in sub plots, the obtained results showed that:
Two field experiments were carried out at al-Gemmiza ,Agricultural Research Station , Egypt El-Gharbia Governorate, during the two successive summer seasons of 2016 and 2017 to study the effect of four nitrogen fertilizer applications, i.e. 75, 90, 105 and 120 kg N/fed and foliar sprays of micronutrient treatments, i.e. Non -fertilized (control) , Zn 0.6 % , Mn 0.6 % , Fe 0.6 % and (Zn 0.2 % + Mn 0.2% + Fe 0.2 %) on the growth , yield and its component and some chemical properties of maize grains of the single cross (Sc 10 ). The experiments were laid out in a split plot design in a randomized complete block arrangement with four replications. The four nitrogen fertilizer applications, i.e. 75, 90, 105 and 120 kg N/fed were allocated in the main plots and foliar sprays of micronutrient treatments, i.e. Non -fertilized (control) , Zn 0.6 % , Mn 0.6 % , Fe 0.6 % and (Zn 0.2 % + Mn 0.2% + Fe 0.2 %), occupied the sub plots. The results can be summarized as follows : All traits of maize under study (plant height , No. of green leaves /plant and leaf area index at 100 days from planting , ear length, ear weight, weight of kernels/ear, 100-kernel weight , kernels shelling % , biological yield/fed , grain yield /fed , stover yield /fed , harvest index % , kernels nitrogen uptake/fed , kernels protein yield /fed , leaf and kernel nitrogen contents , zinc, manganese and iron contents of maize leaves in the two seasons ) showed significant increase by increasing nitrogen fertilizer rate , except, mid tasseling and silking dates , while significantly decreased with increasing nitrogen rates and kernel zinc, manganese and iron contents in both seasons. Application of 120 kg N/fed significantly gave the maximum values of previous traits. Results revealed that mixed micronutrient foliar spray using (Zn 0.2 % + Mn 0.2% + Fe 0.2 %) treatment was the highest treatment for previous growth maize in both seasons. Meanwhile, maize plants which were foliar sprayed singly by Zn 0.6 % , Mn 0.6 % or Fe 0.6 % significantly gave the higher values of leaf zinc content , manganese and leaf iron contents , respectively, except leaf and kernel nitrogen contents, in both seasons . The interaction between nitrogen fertilizer of 120 kg N/fed. and foliar spray by the mixture (Zn 0.2 % + Mn 0.2 % + Fe 0.2 % ) treatment gave the greatest values of maize traits, i.e. plant height, No. of green leaves/plant and leaf area index at 100 days from planting , No.of kernels/ear, ear weight, weight of kernels/ear, biological yield/fed , grain yield/fed , kernels nitrogen uptake/fed. and kernels protein yield/fed except 50 % tasseling and silking dates , ear length , 100-kernel weight , kernels shelling % , stover yield/fed., harvest index % , leaf and kernel nitrogen contents , zinc, manganese and iron contents of maize kernel in both seasons . It could be concluded that fertilization of maize plants by 120 kg N/fed. and foliar spray by (Zn 0.2 % + Mn 0.2% + Fe 0.2 % ) maximized grain yield / feddan under Gharbia Location .
