growth, yield and its components, as well as chemical constituents in cloves and bulb storability of garlic (Allium sativum L.) cv. Sids-40 under three levels of nitrogen (90, 120and 150 kg N/fed) and four levels of elemental sulphur (0, 50, 100 and 150 kg S fed -1).The experiment was laid out in split plot design with three replications assigning nitrogen levels in the main plots and sulphur levels in sub-plots. The results of this study revealed that application of nitrogen and sulpher and their combinations had significant effects on most of the studied characters. The maximum plant height (80.91cm), leaf number (11.96), bulb diameter (6.40cm), and number of cloves per bulb (21.33) and bulb yield (8980 kg fed -1 ) were observed with N 150 S 150 treatment. While the minimum plant height (52.64cm), leaf number (7.91), weight of bulb (58.40g) and projected yield (6620 kg fed -1 ) were observed under N 09 S 0 treatment. S at 150 kg fed -1 and nitrogen at 90 kg/fed recorded the minimum physiological loss in weight (%) for garlic during the storage period (6 monthes). However increasing nitrogen and decreasing sulphur level had adverse effect on storability of bulbs. Sulphur fertilization increased the Allicin concentration from 13.87mg g -1 in the control treatment to 26.59mg g -1 dry weight at 150 kg S fed -1 after 2 weeks of storage period. Allicin decreased gradually in the garlic cloves during the storage period (12 weeks).

Two field expereriments were carried out on sandy soil at a private farm, at El-Shaarawey Village, El Bustan Region, El Behira Governorate located at lat. 30° 43' 22.01"N, long. 30° 13' 44.50" E. during two consecutive seasons at 2012/2013 and 2013/2014.The study was to assess the influence of appling K as soil addition alone or in combination with K foliar application and foliar applied humic substances (HS) at two rates (1 and 2 g/L) in absence or presence of foliar applied molybdenum (6 ppm) on the yield productivity of faba bean plants (C.V Nubaria 1). The results could be summarized in the following points:Data inferred that molybdenum had a significant promotive effect on weight of pods/plant, 100-seed weight, straw, pod and seed yields. Also, the data indicated that content of N%, K% and their uptake , as well as protein% were significantly increased due to foliar application of molybdenum .Soil application of the half recommended rate(HR) of K with foliar spray of HS (1 or 2 g/L) or 1% potassium sulphate, irrespective of molybdenum treatments, gave the most positive effect on yield, its components, and uptake of N,P and K in seeds compared to sole application of full or half recommended rate with no significant differences in most cases.The highest pod or seed yield as well as weight of pods/plant were achieved by application of 50%-K along with foliar HS (1g/L) while, the highest 100-seed and straw yield were recorded by using HS (2g/L). The interaction effect on the studied characters notably appeared in the triple treatment of K-50% as soil addition with foliar application of humic substances at rate (1g/L) and molybdenum (6 ppm) which was superior to others and achieved the significant effect on 100-seed weight, straw yield, N%, P% ,K% and protein %, as well as N, P and K uptake.

Two field experiments were carried out at El-Sharawy village in ELBostan area-Noubaria Region, Elbeheira governorate Egypt, (Latitude 30° 43' 22.01" N, Longitude 30° 16' 44.50" E), during the two growing successive seasons of 2012/2013 and 2013/2014, to study the effects of compost, nitrogen application levels and Humic substances as foliar sprays on wheat yield as well as some nutrient contents in wheat grain and straw, grain protein content and total carbohydrate of wheat plants (Masr-1 variety). A split-split plot deign with three replicates was used. The main plots were assigned for two rates of compost (0 and 10 m 3 /fed), the sub-sub plots were assigned for three levels of nitrogen treatments while sub-sub plots were assigned for two Khumate treatments i.e. without addition and foliar application at 2 L fed-1. The obtained results revealed that application of compost significantly increased the wheat grain and straw yields and their contents of N, P, K and grain protein. Raising mineral nitrogen fertilizer level from 50 to 75 and 100 % resulted in significant increases in 1000-grain weight, grain and straw yields/fed and protein content of grain and straw as well as N, P and K content in grain and straw. Foliar application of K-humate generally had enhancing effects on wheat productivity and improved its nutrient contents. In this concern, the soil application of 10 m 3 compost together with mineral nitrogen fertilizer at of the recommended N 75 or100 % level and 2 L fed-1 K-humate had the superior impact.
