seasons to investigate the effect of different methods and rates of fulvic acid (FA) and Zn on yield and its components of maize. In both seasons, the two filed experiments were set up in a randomized complete block design (RCBD) with three replications. The treatments were as follows; The control treatment (T1), soil application of FA at the rate of 12 kg/ha at 30 and 45 DAS (T2), soil application of Zn at the rate of 12 kg Zinc sulphate/ha at 30 and 45 days (T3), spraying of FA at the rate of 1.2 kg/ha at 40 and 50 days (T4), spraying of Zn at the rate of 1.2 kg/ha at 40 and 50 days (T5), soil application of FA and Zn at the rate of 12 kg/ha at 30 and 45 days (T6), spraying of FA and Zn at 40 and 50 days (T7), soil application of FA and spraying of Zn (T8), and soil application of Zn at 35 and 45 days and spraying of FA at the rate of 1.2 kg/ha at 40 and 50 days (T9 in both seasons. The results showed that soil application of Zn at 35 and 45 days and spraying of FA at 40 and 50 DAS (T9) gave the highest mean values of yield and its components of yellow hybrid of maize followed by soil application of FA and spraying of Zn (T8) which gave the same trend while the control treatment recorded the lowest mean values of the studied characters of maize in both seasons under this study conditions.

After sugarcane, sugar beet (Beta vulgaris L.) is regarded as the second most significant sugar crop. It is an edible plant of the Amaranthaceae family. It is an essential crop for humans as a source of high energy and as a source of feed for livestock. The significance of this crop stems from its ability to grow on the recently reclaimed ground and provide a high sugar recovery rate, as well as its lower water need when compared to sugarcane.Furthermore, sugar beet is specialized as a short-duration crop, with a growth time around half that of sugarcane. Furthermore, being the most significant cash crop in the cycle, sugar beet leaves the land in good condition for the next summer grain harvest. As a result, it became the first source of sugar production in Egypt. (Amr and Ghaffar, 2010).Sugar beet production accounted for 67.7 % (1.8 million tons) of total sugar production in Egypt. The total sugar beet cultivated area in Egypt reached 617000 feddans. However, the total sugar beet cultivated area in the world is estimated to be 12.5 million

Two field experiments were carried out at Itay El-Baroud Experimental station in El-Beheira Governorate, Agriculture Research Center, Egypt in the 2019/2020 and 2020/2021 winter seasons to study the effect of four different systems to display the ridge in the planting of sugar beet (ridge width 110 cm (Rw1), ridge width 100 cm (Rw2), ridge width 90 cm (Rw3) and ridge width 80 cm (Rw4), four nitrogen fertilizer levels (75 kg N /fed (N1), 90 kg N /fed (N2), 105 kg N /fed (N3) and 120 kg N /fed (N1) and three systems of boron foliar spray (zero boron (B0), foliar spray once of boron at 95 days from sowing (B1) and Foliar spray twice of boron at 95 and 125 day from sowing (B2) on growth, yield and quality characters of sugar beet. Results showed that planting sugar beet on a wider ridge of 110 cm recorded the highest chlorophyll content and crop growth rate while planting sugar beet on a narrow ridge of 80cm resulted in the highest leaf area index. Grown sugar beet on a narrow ridge of 90cm resulted in the highest root yield, sugar yield /fed and quality in both seasons. Increasing nitrogen fertilizer levels from 75 to 90, 105 and 120 kg N /fed significantly decreased root yield, sugar yield/fed and quality in both seasons. Whereas increasing foliar spray of boron from zero to one and twice foliar spraying increased root yield, sugar yield/fed and quality. It could be concluded from these results that planting sugar beet on ridge narrow of 90 cm, 75 kg N/fed and twice foliar spraying of boron are the suitable recommendation to maximize sugar beet productivity and quality.
