Artichoke seeds germination shows variation in germination percentage and speed with non-uniform seedlings. Two labratory and nursery experiments were carried out during seasons of years 2011/2012 and 2012/2013 to investigate the enhancement role of seed priming agents on seed germination and seedling behvior of locally produced seeds of globle artichoke <em>Cynara scolymus</em> L (green globe CV.).Seeds were primed in 8 different priming agents (PEG 8000, KNo<sub>3</sub>, K<sub>2</sub>HPO<sub>4</sub>, Na<sub>2</sub>SO<sub>4</sub>, NaCl, MgSO<sub>4</sub>, KCl, or Mannitol.) plus the control treatment (without priming). Both germination under laboratory conditions and emergence under nursery conditions were evaluated.
Germination percentage, coefficient of velocity and germination performance index were significantly increased as a result of seed priming treatments. KNO<sub>3</sub> , PEG and mannitol were found to be the best treatments in this regard. Priming artichoke seeds in different priming agents reduced mean germination time and time required to reach 50% germination.
KNO<sub>3</sub> , PEG and mannitol significantly improved the seedling characters in terms of seedling length and seedling fresh and dry weights as well as amylase activity. However, K2HPO4 was the best treatment in activating theperoxidase enzyme.
Emergence and subsequent growth of seedling in trays responded positively to seed priming and KNO<sub>3 </sub>was the suprior in enhancing emergance percentage and seedling growth in terms of seedlings height, number of leaves and dry weights of shoots and roots.
It could be recomended that, priming local produced artichoke seeds in KNO<sub>3</sub> , PEG and mannitol will enhance seed germination and subsequent seedling growth which in turn will lead to using seed as a new method for propagtion and multplication under Egyptian condition and subsequently the cultivated area with artichoke will increase.

The present study was carried out during three successive seasons (2011, 2012 and 2013). (the first year was considered as a preliminary trial) on ten years old Flame seedless grape vines cultivated in a private vineyard at 64<sup>th</sup> kilometer Cairo-Alexandria desert road. The main of study was to evaluate the effect of using organic fertilizer as compost in combination with or without two natural rocks ; Rock Phosphate and Feldspar. Also three different biofertilizers were used; Biogen (<em>Azotobacter chroococcum</em>) for N, Phosphorien (<em>Bacillus Megathrium</em>) for P and Potasiumag (<em>Bacillus circulans</em>) for K in comparison with the mineral fertilization , yield and its components as ( number of clusters per vine and cluster weight), physical and chemical characteristics of berries, and nitrite and nitrate content in berry juice of Flame seedless grapevine.
The results revealed that using combined application of%100 compost, natural rocks and the three biofertilizers of NPK were very effective in increasing yield per vine and per feddan, cluster number per vine and weight, physical and chemical properties of berries were significantly improved. On the other side, Both nitrate and nitrite content in berry juice of Flame seedless grapevines were minimized comparing with the vines received 100% mineral fertilization or 100% compost alone. Furthermore, organic agriculture is very safe for human and environment by reducing pollution via improving soil nutritional status as well as decreasing mineral fertilization and that will be reflected on yield and quality of the grapes.

Two field experiments were conducted at Baramoon Research Station, Mansoura, Dakahlia Governorate, Egypt during the two successive seasons of 2011/12 and 2012/13, to study the effect of foliar spray with boron (25 and 50 ppm) or potassium (1000 and 2000 ppm) and their combination on earliness, yield and quality, chemical composition as well as seed yield of globe artichoke (<em>Cynara scolymus</em> L.) c.v green globe.
<strong>The obtained results could be summarized as follows:-</strong>
Early yield, total yield and head characters were significantly increased, in both seasons, in response to foliar spray with boron or potassium levels and there mixture.
Foliar spray with 50 ppm B + 2000 ppm K significantly affect the concentration of N,P,K,total sugars and inulin of globe artichoke in both seasons of study<strong>.</strong>
Number and weight of seeds /head as well as weight of100 seeds and germination percentage on different orders were positively and significantly responded to foliar spray with boron or potassium levels and their mixture in the two seasons. While, No significant difference was found between 50 ppm B + 2000 ppm K or 50 ppm B + 1000 ppm K.
In general, most studied characteristics of the plants received foliar spray with boron and potassium were better than those of control. Increasing the rate of foliar spray with boron and <strong>/</strong>or potassium significantly increased early yield total yield, head characters ,chemical components and head position characters including number and weight of seeds/ head as well as weight of100 seeds and germination percentage.
It could be stated that, foliar spray of globe artichoke with boron at 50 ppm and potassium at 1000 ppm is a promising practices for getting the highest seed yield and quality under local Egyptian conditions

Seeds of legumes are extremely important crop plants which are widely cultivated in Egypt. Climate changes are the most important challenge facing agriculture today. Two field experiments were conducted at the Horticulture Research Farm Elbaramon during 2010 and 2011 seasons to determine the effect of different seeding dates and the plant distribution system on growth, yield and quality of common bean (<em>Phaseolas vulgaris</em> L. cv. Nebraska). The treatments were three sowing dates 20 Feb., 10 and 30 March and four plant distribution systems, <em>i.e</em>., 5 and 10 cm plant spacing on one or both sides of the row. The plant length, number of leaves, number of branches, the grain yield, number of seeds per pod, dry weight of seeds per pod, 100 seeds weight, biological yield, harvest index and chemical analysis of bean seed were affected significantly by sowing dates and the plant distribution system. The highest values of all these characters were recorded on 10 March and the lowest values of them were recorded on 30 March. Among four plant distribution system highest value of seed yield was obtained in 5 cm plant spacing on two sides and the lowest value was measured in 10 cm on one side. Further, sowing common bean seeds on 10 March with 5 cm on two sides had the best results for seed yields under the same conditions.

Two field experiments were carried out on at Baramon Research Station- Horticulture Research Institute during the winter season 2009/2010 and 2010/2011 lettuce to improve the growth, head and seed yield by enhancing the metabolic processes. Two weeks after transplanting, plants were sprayed (spraying were repeated every two weeks), the treatments were as following: seaweed extract, humic acid complex, NPK (8-8-8), amino acids mixture, Ascorbic acid (VC), Vitamine E+ Selenium and control. The effect of these treatments on vegetative growth, biological constituents, photosynthetic pigments, flowering, head and seed yield were studied. The results can be summarized as following: most treatment surpassed the control in all studied characteristics, as they promoted lettuce performance and yield under the experiment conditions. The best treatment was the seaweed extract; it significantly increased most of vegetative characteristics, biological and chemical parameters which led to the increase of head and seed yield in the two seasons of the experiment. It resulted in 50% increase in head yield and 100% increase in the seed yield. Therefore, it’s recommended to spry lettuce plants with seaweed extract (5ml L<sup>-1 </sup>) four times during the season in order to get the highest head and seed yield

Inoculation with phosphorien-containing phosphate-dissolving bacteria (PDB) and/or foliar application of magnesium (Mg) at the rates of 0, 0.5 and 1 mM on the growth, some chemical constituents and fruit yield and yield quality of pumpkin (<em>Cucurbita moschata</em> Duchesne) grown on a sandy calcareous soil were investigated.
Two field experiments (2012 and 2013) were performed in a completely randomized blocks design with six treatments, each with four replicates. The results indicated that PDB and/or Mg significantly increased stem length, canopy dry weight plant<sup>–1</sup>, number of leaves plant<sup>–1</sup>, total leaf area plant<sup>–1</sup>, leaf area leaf<sup>–1</sup>, leaf contents of pigments, free proline, nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), and calcium (Ca) and the ratio of Ca/Na, while leaf Na content was reduced. The application of PDB and/or Mg also increased fruit yield and yield quality (fruit length and diameter, flesh thickness, average fruit weight and fruit yield fed<sup>–1</sup>). It could be concluded that that PDB and Mg have pronounced positive effects on the growth, fruit yield and yield quality of pumpkin plants grown on sandy calcareous soil. PDB and Mg, therefore, have the potential to be used as a soil inoculation and foliar application, respectively for various crops to overcome the adverse effects of the newly-reclaimed sandy calcareous soils.

Two field experiments (2012 and 2013) were performed on a newly-reclaimed saline soil using a design of completely randomized blocks with six treatments, each with four replicates. Results indicated that SAS and/or FAA increased growth traits (i.e., stem length, canopy dry weight plant<sup>–1</sup>, number of leaves plant<sup>–1</sup>, average leaf area and total leaf area plant<sup>–1</sup>), fruit yield and yield quality (i.e., fruit length and diameter, flesh thickness, TSS, average fruit weight and fruit yield fed<sup>–1</sup>), leaf concentrations of N, P, K, S and AsA, and K/Na ratio. In contrast, leaf concentration of Na was reduced as a result of SAS and/or FAA. SAS and FAA, therefore, have the potential to be used as a soil and foliar applications, respectively for pumpkin to overcome the adverse effects of the newly-reclaimed saline soils.

True seeds of twenty sweet potato lines were collected and used for croup production. The six hybrids were evaluated in a randomized complete blocks design with four replicates with best two check cvs (Mabrouka and Abees) for some morphological and root yield characters at Motopous conditions Kaferel Sheikh, Governorate . Differences were found among the F1 hybrids in all studied traits. All the F1 hybrids significantly exceeded the two cheek cvs. The percentage of increase in the hybrids with Mabrouka cv. was ranged from (168%) in the hybrid No (1) to (51.5%) in the No (3). While it ranged from (173%) to (56%) compared with Abees cv. Average tuber root was highly significant in hybrids No (4) compared with the two check cvs. Two degrees of skin colour, i.e., purple and dark purple, were observed in roots of the hybrids, while six degrees of flesh colour from white to purple were noticed in this study. Most of F1 hybrids significantly exceeded the to check cultivar in most studied traits. Hybrid vigor attributed to over dominance was detected in total tuber root yield and the other studied traits. Dominance in complete and partial was also observed.

Two field experiments were conducted during the two successive seasons of 2012 and 2013 at Sakha Agricultural Research Station, Kafrelsheikh to investigate the efficacy of some weed control treatments for controlling total annual weeds as well as yield and chemical composition for maize grains. The weed control treatments were acetochlor, fluroxypyr and bentazone plus one hand hoeing at 30 days after sowing in addition to the hand hoeing twice.
Results indicated that the hand hoeing twice or the herbicides (acetochlor, fluroxypyr and bentazone) plus one hand hoeing were effective in controlling broad-leaved, grassy and total annual weeds at two surveys in both seasons. Whereas, these treatments suppressed dry weight of total annual weeds at least by 93.3 % than un-weeded control treatment. Also, the results revealed that all weed control treatments increased maize plant height, ear length, ear diameter; ear grains weight, shelling percentage, 100- grain weight and grain yield/fed.
The results showed that all treatments gave a noticeable increase in protein and oil contents of the grains, and a decrease in phenols content. Also, all treatments affected slightly carbohydrates, starch%, amino acids contents and fatty acids composition of maize grains as comparing with the control treatment.
It can be concluded that all the applied weed control treatments, whether, hand hoeing twice or (acetochlor, fluroxypyr and bentazone) plus one hand hoeing could be recommended for optimum weed control and grain yield of single hybrid maize c.v. single cross 10 (SC<sub>10</sub>). These practices gave a promising reduction of total annual weeds and increased maize yield and its components. Thus, these herbicidal treatments can replace hand hoeing for the control of total annual weeds in maize crop.

Two field experiments were carried out during the two successive seasons of 2010/2011 and 2011/2012 in the Farm of Agric. Res. Station, Wady El-Natrown Area, Fac. Agric. Cairo University, Egypt under saline water and sandy soil conditions. This investigation aimed to study the effect of compost, natural alternative fertilizers (rock phosphate and feldspar) combined with bacterial inoculation (<em>Azotobacter spp </em>and <em>Azospirillum perna + B. megaterium + B. circulans</em>) on yield, tubers quality and its component of (dry matter, NPK, carbohydrate and nitrate) of potato tubers Diamant cultivar.<em> Azotobacter spp </em>and <em>Azospirillum perna</em> were used as nitrogen fixing bacteria from compost, <em>B. megaterium </em>was used as phosphate dissolving bacteria from rock phosphate and <em>B. circulans </em>was used as potassium dissolving bacteria from feldspar. The experiment included 13 treatments as follows three compost levels source of (N) (5.9, 8.8, 11.8 ton/fed.), three rock phosphate levels source of (P) (204.4, 140.7, 77.04 kg/fed.) and five feldspar levels source of (K) (888.8, 592.6, 580.7, 333.3, 251.9 kg/fed.) compared with control (mineral NPK at rate of 120 N -75 P<sub>2</sub>O<sub>5 </sub>- 96 K<sub>2</sub>O kg/fed.) were applied in a (RCBD) randomized complete blocks design with three replicates. Results at harvest showed that significant increases in yield characteristics as (yield/plant, total yield, number of tubers and weight of tubers/plant) and tubers quality (dry matter, carbohydrate, nitrate) were treated with high rate of compost (11.8 ton/fed.) combined with potassium at the highest rate in the presence of bacterial inoculation mixture and showed significantly increasing compared with control. Therefore, compost, rock phosphate, feldspar and biofertilizers could be an alternative to mineral fertilizer for potato production.
