In addition to assessing the effect of mature (FYM), sediments (separated from extract), and both foliar application of extracts of farmyard manure (as organic farming technique) and mineral fertilizer treatment (as conventional cultivation system) on the quality and yield of potato (Solanum tuberosum, L.) and soil health (physical, chemical and biological properties) after harvesting stage. Nine treatments were arranged in a complete randomized block design with four replicates, (mineral NPK, mature FYM, watery FYM extract, watery sediment, watery FYM extract with sediment, ethanolic FYM extract, ethanolic sediment, ethanolic FYM extract with sediment, and control treatment). FYM extracts were sprayed on plant foliage, while others were added as soil application. The soil application of mineral fertilizer (as conventional system) has the highest significant values for all vegetative growth parameters, yield, yield components, of potato comparing with other organic treatments. In contrary, the soil application of FYM achieved the highest values for improving soil health after harvesting stage (including soil physical, chemical and biological, properties), also reducing the accumulation of NO3- and NO2- contents in potato tuber. FYM application methods (as organic system) enhanced all studied potato vegetative growth parameters, quality and quantity of the yield and also improve soil health, compared to the untreated treatment. For all potato plant growth parameters, FYM application methods can be arranged in the order: spraying of ethanolic FYM extract with its sediment> spraying of watery FYM extract with its sediment> spraying ethanolic FYM extract> spraying watery FYM extract> mature FYM> watery sediment> ethanolic sediment. While, for improving soil health parameters the soil application of mature FYM gave the highest values followed by spraying of watery FYM extract with its sediment> ethanolic FYM extract with its sediment> watery sediment> ethanolic sediment. Furthermore, it was observed that ethanol as extractor was more effective than water and consequently  spraying ethanolic FYM extract with its sediment or alone achieved higher values for all potato growth parameters compared to spraying of watery FYM extract either with or without its sediment.}, keywords = {}, url = {https://jssae.journals.ekb.eg/article_55420.html}, eprint = {https://jssae.journals.ekb.eg/article_55420_c767c3b4c1be7d139eb1518599ea2a58.pdf} } @article { author = {Abou-Zied, S.

The experiment contained two active organic acids treatments, i.e., humic acids as K-humate or fulvic acids as K-fulvate  were used as soil application and foliar spray as solely treatment or incorporated together at five rates of 0, 5, 10, 15 and 20 L fed-1  from humic or fulvic acids as soil application or (0, 50, 100, 150 and 200 ppm) as foliar spray as compared with the combined treatment on some physical properties i.e., bulk density, total porosity, moisture constants (field capacity, wilting point and available water), hydraulic conductivity and chemical properties i.e., pH, EC, organic matter and availability of N, P and K in clay loam soil. On the other side, the positive effect of these treatments on cucumber yield and its content of nutrients were taken into consideration.        Generally, results indicated that application of organic acids as soil application incorporated with foliar spray was more effective on improving soil and plant parameters under studied, followed by soil and foliar application as solely treatment, especially at the fourth rate of 20 L fed-1as soil application and 200 ppm as foliar spray.

The irrigation treatments were based on cumulative pan evaporation (CPE) at different empirical pan factors (0.6, 0.8, 1.0, 1.2, 1.4 and 1.6 of CPE. Irrigation interval was based on available water = Ef * CPE. Results indicated that reducing the irrigation interval through increasing empirical pan factor (Ef) value from 0.6 to 1.6 has a highly significant effect on fresh seed yield. The highest mean fresh seed yield in the two seasons (1066.5 kg/fed.) was obtained when irrigation was done at Ef 1.6 and the lowest fresh seed yield (507.5 kg/fed.) was obtained when we use Ef 0.6.  The highest value of crop water productivity CWP (0.93 kg/m3) was obtained by using Ef 1.6 and the lowest CWP (0.45 kg/m3) was obtained by using Ef 0.6 .  The highest value of biological yield (7.67 ton/fed.) was get with the treatment of Ef 1.4, where the lowest value (5.16 ton/fed.) was resulted from the treatment irrigation at Ef 0.8. Studied treatments have highly significant effects on fresh pod yields. The highest fresh pod yield (2.98 ton/fed.) was produced from treatment irrigation at Ef 1.6, where the lowest value (1.94 ton/fed.) was obtained by using Ef 1.0. Insignificant differences were found between the studied treatment means regarding to weight of 100 seeds and percentage of moisture in seeds. Number of seeds/pod was high significantly influenced by studied treatments. The number of seeds/pod (9.0) resulted from 1.6 as Ef treatment. While, the lowest number of seeds/pod (7.2) was obtained from Ef 0.6 treatment. The highest value of netting percentage 36.1% was obtained from irrigation at Ef 1.2 and 1.6 treatments, while the lowest 21.2% was obtained from irrigation at Ef 0.6 treatment. The highest mean value of pod filling (0.86) was resulted from irrigation at Ef 1.0, 1.2 and 1.6 treatments.

The overall objective of this research was to assess the ground water resources quality for an agroecological system in Behaira governorate. To achieve this objective, water samples of 59 well at depth’s 15 to 40 m were taken and chemical as well as heavy metal analyses revealed that: pH values varied from slightly alkaline to alkaline.

According to USDA diagram, the majority of the studied water samples were in class C3S1 (slightly dangerous for irrigation purposes.
