This study was conducted in research farm and laboratories of Horticultural Research Institute, Agric. Res. Center during the period from 2012 to 2014 to estimate heterosis, and both general and specific combining abilities of some pumpkin (<em>Cucurbita maxima</em> Duch. ex Poir.) economical traits, <em>viz</em>., main stem length, number of branches/plant, number of nodes to first female flowers, average length, diameter and weight of fruit, average flesh thickness, number of fruits/plant, and total yield/plant. Five different inbred lines of pumpkin, namely <em>PK 27A</em> (P<sub>1</sub>), <em>PK 27</em> (P<sub>2</sub>), <em>PK 26</em> (P<sub>3</sub>), <em>PK 33</em> (P<sub>4</sub>), and <em>PK 31A</em> (P<sub>5</sub>) were used for carrying out half diallel cross in all possible combinations excluding reciprocal. Results showed that the maximum significant true heterosis in desirable direction (71.8%) was recorded for TY followed by NB (67%), AFW (41.9%), NF (40.5%), MSL (39.5%), NNF (29.1%), AFL (28.7%) and AFD (12.4%). Analysis for combining ability indicated that general (GCA) and specific combining ability (SCA) variances were highly significant, indicating that both additive and non-additive gene effects involved in the expression of all studied traits except for NB and NF traits which were mainly controlled by non-additive and additive types of gene action, respectively. The ratios of GCA/SCA were higher than unity suggesting that the additive and additive by additive type of gene action was more important for most traits. Based on general combining ability effects, the parental lines P<sub>3,</sub> P<sub>4 </sub>and P<sub>5</sub> were good combiners for most studied traits. The highest desirable SCA and heterotic effects were obtained from the crosses; (P<sub>1</sub> × P<sub>4</sub>), (P<sub>2</sub> × P<sub>3</sub>) and (P<sub>3</sub> × P<sub>5</sub>) for yield and most of the studied traits, which are the best and promising hybrids.

Laboratory experiments were conducted at the laboratory of Seed Technology Research Section, Mansoura during 2013 and 2014 years to study the effect of soaking wheat seed of. Misr 1, Misr 2 and Gemmiza 10 cultivars in six salty solutions i.e. CaCl<sub>2</sub> 2%, CaCl<sub>2</sub> 4%, KH<sub>2</sub>PO<sub>4</sub> 1%, KH<sub>2</sub>PO<sub>4</sub> 2 %,KCL 2 %, KCL 4% and in addition to water and dry seed on germination percentage, seed and seedling vigor as well as seedlings chemical measurements under salinity conditions (0, 5 and 10 dS/m). The results revealed that: Increasing salinity levels not only reduced seed germination but also decreased seed vigor measurements which measured by (speed germination index, germination rate and co-efficient of germination). Seedlings measurements at the highest salinity levels (10 dS/m) were most weakness comparing (0 and 5 dS/m). Cholorophll a , b, carotenoids , K<sup>+</sup> content and K/ Na ratio decreased at high salinity levels. Misr 2 wheat cultivar showed superiority and recorded the highest values of water uptake %, seed and seedling vigor, chemical measurements and lowest Na <sup>+</sup>content .While, Gemmiza 10 wheat cultivar was the lowest of all studied measurements and the highest of Na <sup>+</sup> content. The highest values of seed, seedling vigor, chemical measurements (cholorophll a, b, carotenoids, K<sup>+</sup> contents, and K/Na ratio) and lowest Na<sup>+</sup> content in seedlings were obtained by wheat priming in KH<sub>2</sub>PO<sub>4</sub> 1%solution.
In general, under salinity conditions, It could advised sowing seed of Misr 2 wheat cultivar and treated with KH<sub>2</sub>PO<sub>4</sub> 1%solution to improved seed germination, seedlings vigor and mitigation the harmful effect of salinity according to the obtained results in this investigation.

The present investigation was conducted during 2012, 2013 and 2014 seasons on 10-year-old Superior grapevines cultivar grown in a sandy soil, planted at 2 m within rows and 3 m between rows and irrigated using drip irrigation system at a private vineyard located at El-Khatatba, Menoufiya governorate, Egypt. The obtained data was discussed in details for the last 2 seasons only. The main objective of this investigation was to study the effect of fulvic acid foliar application 9 ml/liter /vine, either alone or in combination with micro-elements (Fe SO<sub>4</sub>. 7H<sub>2</sub>O at 0.36 g + Zn SO<sub>4</sub>.7H<sub>2</sub>O at 0.18 g + MnSO<sub>4</sub>. H<sub>2</sub>O at 0.18 g) and bio-fertilizers (<em>Trichoderma viride</em> + <em>Trichoderma harzianum</em> + <em>Serratia sp</em>. + <em>Pseudomonas fluorescens</em> + <em>Bacillus polymyxa</em>) at 7.14 ml/liter/vine (10<sup>4</sup>/ml per fungi and 10<sup>9</sup>/ml per bacteria viable cell) on vegetative growth, total chlorophyll content, yield, physical and chemical characteristics of cluster and quality of berries, total carbohydrates, total N and C/N ratio in canes of Superior seedless grapevines. Results revealed that the combined treatment of fulvic acid, micro-elements plus bio-fertilizers induced indispensable positive effects for enhancing vegetative growth, total chlorophyll content, yield, physical and chemical characteristics of cluster and quality of berries, total carbohydrates, total N and C/N ratio in canes of Superior grapevines. A stronger effect may probably support the hypothesis of that humic substances have different effects on plant adequately supplied with nutrients, in sustainable or organic viticulture for production of organic products, which can be a noteworthy alternative to synthesized chemicals fertilizers to produce a healthy product-free from their toxic residues and fit for export. Foliar spray applications of these products can have prospects for optimal economical use in terms minimizing the cost of production and in turn increased the income of vineyards.

This study aimed to estimate the combining ability and gene action for eight flax genotypes under sandy soil conditions. This was achieved via evaluating the eight parents and their 16 F<sub>1</sub><sup>,</sup>s progenies. The eight parents consisting of four females (P<sub>1</sub>= S.541-C/6, P<sub>2</sub>= S.402/1, P<sub>3</sub>= S.813, and P<sub>4</sub>= S.997) and four males (P<sub>5</sub>= Sakha 3, P<sub>6</sub>= S.541-C/7, P<sub>7</sub>= Sozana and P<sub>8</sub>= S.541-D/4). In 2013/14 season, each of the four male parents was crossed to the four female parents to obtain 16 F<sub>1</sub> crosses at the breeding nursery of Fiber Crops Res. Section, ARC at Giza. In 2014/15 season, the parents and their 16 F<sub>1</sub>,s seeds were evaluated in Ismailia Exp. Station, Ismailia Governorate. The experiment was laid out in a randomized complete block design with four replications.
The collected data indicated that the values of additive and dominance as well as, the ratio of GCA/SCA indicated that additive played greater role than non-additive gene effects in the inheritance of straw yield per plant, plant height, technical stem length, no. of basal branches and 1000-seed weight. Therefore, selection should be possible within the F<sub>2</sub> and subsequent populations for these characters. On the other hand, the ratio of GCA/SCA revealed that non-additive played greater role than additive gene effects in the inheritance of seed weight per plant, no. of capsules per plant and no. of seeds per capsule. P<sub>1</sub> and P<sub>5</sub> among parents were outstanding as they showed significant desirable combining ability for straw yield per plant and in most important components as well as P<sub>5</sub> for technical stem length and P8 for both straw yield per plant and no. of basal branches per plant. On the other hand, P<sub>1</sub> and P<sub>8</sub> among parents are good general combiners for seed yield and most of its components, indicating that the use of these parents in flax breeding programs could be increase the above mentioned treats. Only one cross (P<sub>4</sub>xP<sub>5</sub>) exhibited significant positive SCA effects for straw yield and its components as well as this cross included high x low general combiner parents for straw yield per plant and two important components, plant height and technical stem length. Also, one cross (P<sub>1</sub>xP<sub>5</sub>) for both plant height and technical stem length, in addition one cross (P<sub>1</sub>xP<sub>6</sub>) for both straw yield/plant and plant height included high x high general combiner parents. For seed yield, three crosses (P<sub>1</sub>xP<sub>5</sub>, P<sub>1</sub>xP<sub>6</sub> and P<sub>4</sub>xP<sub>8</sub>) exhibited significant positive SCA effects for seed yield per plant and no. of capsules per plant as well as high x low general combiner parents. Also, three crosses (P<sub>1</sub>xP<sub>5</sub>, P<sub>1</sub>xP<sub>7</sub> and P<sub>4</sub>xP<sub>8</sub>) exhibited significant positive SCA effects for no. of seeds per capsule included high x low general combiner parents. While, out of the previous crosses, three crosses (P<sub>1</sub>xP<sub>5</sub>, P<sub>1</sub>xP<sub>6</sub> and P<sub>4</sub>xP<sub>8</sub>) only included high x high general combiner parents for 1000-seed weight. These crosses were involved one good combiner parent, which indicated that such combinations are expected to throw desirable transgressive segregates. It could be concluded that the above mentioned crosses would be interesting and prospective for the future in flax breeding program for improving seed yield and straw yield and their components.

This study was designed and implemented to evaluate productivity of three cereal crops <em>i.e.</em> Wheat, Barley and Triticale as affected by different nitrogen levels <em>i.e.</em> 0, 100 and 200 kg N/fed, two field experiments were carried at Exp. Res. Sta., Fac. Agric., Benha Univ. during 2010/2011 and 2011/2012 seasons. Results indicated significant differences in the total fresh forage yield for each of the three crops under study. Highest fresh and dry forage yield was produced from Barley whereas, the lowest yield was obtained from wheat with significant differences of different magnitudes. Highest grain yield and yield component was recorded from sown triticale and the lowest was recorded from sown Barley with significant differences. It could be concluded that total forage and grain yield as well as yield components were substantially increased as nitrogen fertilization levels increased from 0 to 100 and up to 200kg N/fed, respectively. However, an opposite trend was observed for the No of spikelets/spike and spike length.

Genetic stability and diversity are two of the key factors for the improvement of many crop plants. A major challenge for plant breeders is selection of high yielding genotype with wide adaptation. Therefore, thirty six wheat genotypes were evaluated under two locations (Sohag and Aswan, Egypt) on favorable and late sowing date during winter seasons of 2012/2013 and 2013/2014 to estimate its performance and stability parameters. The wide range of weather conditions resulted in a broad variation of mean yields, ranging from 6.59 t/ha in favorable sowing date to 4.99 t/ha in late sowing date as heat stress. The combined analysis of variance showed that the flag leaf area, days to heading, spike length, 1000-kernel weight and grain yield were significantly influenced by years, locations, sowing dates and genotypes. Mean environmental grain yield ranged from 2.70 t/ha to 9.27 t/ha. The results showed that sowing at the favorable date increased all studied traits. The 36 genotypes showed diversity for the slopes of the joint regression. Genotypes No. 5, 6, 14, 19, 20, 22, 24 and 32 exhibited stability for grain yield and useful in the breeding program in developing new wheat genotypes with tolerance to heat stress conditions. Positive correlation was found between b<sub>i</sub> and for days to heading, spike length, number of kernels/spike, 1000-kernel weight and grain yield (0.89**, 0.50**, 0.07, 0.13 and 0.51**), respectively. This might be due to adaptation of these genotypes to wide differences in climatic conditions which prevailed at the two studied locations. The best genotypes in terms of both favorable and heat stress indicating that selecting for improved yield potential may increase yield in wide range of environments.

In order to determine the best planting procedures where three inter spacing (row spacing) and three intra spacing (plant spacing) and their combination. The inter spacing were 20, 30 and 40 cm distances between rows, and the intra spacing between plants were 10, 15 and 20 cm distances between plants and their combinations. Field experiments were conducted at Ismailia Agriculture Research Station, Agriculture Research Center, Ismailia, Egypt during two winter successive seasons of 2012/2013, 2013/2014.
Results indicated that highest grain yield of quinoa was produced when using the narrowest inter species of rows (20 cm) and the narrowest intra spaces of plants (20 cm) with significant interaction effect in each of the two seasons. This result could be accepted due to the well even distribution of plants which reduced the compotation for all of prevailing enormous essential requirements of plants as germination seed line emergence, growth and development which reflected on production and quality. A significant reduction of grain yield was obtained by increasing intra spacing between plants <em>i.e.</em>10, 15, 20 cm. This reduction was notical only at the lowest inter spacing of rows at 20 cm. However at wider inter spaces of plant <em>i.e.</em>30 and 40 cm, increases of intra spaces between plants <em>i.e.</em>10, 15, 20 cm cause sub stand increase in grain yield in the first and second seasons with significant differences in the first seasons.
It could be concluded the best treatment for growing quinoa produced from the inter and intra spacing were the lowest. This may be attributed to the appropriate distribution of plants, which decrease completion among plants and allows it to maximum were of the circumstance surrounding it in the caption soil

Two field experiments were carried out at the Experimental Farm of Rice Research& Training Centre, Sakha, Kafr-El-Sheikh, Egypt, during the two successive summer seasons, 2012 and 2013, to study the effect of rice husk as an organic fertilizer on the performance of two Egyptian rice cultivars. A strip plot design with three replication was used. Rice cultivars (Sakha 106 and E. hybrid rice1) were occupied the horizontal plots .While four rates of fully grounded rice husk (0, 5, 7 and 9 Ton /ha) were devoted to the vertical plots. Growth, yield, yield components, and grains quality characters of two rice cultivars were investigated.
The results showed that the mean values of all the studied characters except cooking and eating quality characters were significantly affected by rice cultivars. Different responses to rice husk rates were obtained for the all studied characters. In most cases, The mean values of these characters increased by increasing rice husk rates and maximized at the rate of 9.0ton /ha., and no significant was found between 7 ton/ha and 9 ton/ha, while, number of days to 50% heading and cooking and eating quality didn’t affected by rice husk at any rate in both seasons. The interaction between cultivars and rice husk rates under study had significant effect on most tested characters, it was detected in two or/and one season of study. Meanwhile, this type of interaction was not significant regarding all grain quality characters in the two seasons of study. This study suggested that rice husk could be applied as organic fertilization (7 ton /ha) with 50% of recommended dose of nitrogen (72 kg N\ha).

Two field experiments were carried out during the fall seasons of 2012 and 2013 at the Agriculture Research Farm, El-Kassasien Hort. Res. Station, Ismalia Governorate, Egypt, and storage Lab., Hort. Dept., Fac. of Agric., Zagazig University, to study the effect of seed and soil inoculation (arbuscular mycorrhizal fungi, soil yeast) as well as foliar application with some natural materials (pigeon manure tea, compost tea, humic acid and effective microorganisms) on growth, photosynthetic pigments, yield and its components as well as chemical constituents of snap bean pods (<em>Phaseolus</em> <em>vulgaris</em> L.) cv. Paulista. It aimed also to study the effect of the abovementioned treatments on snap bean pods storability during cold storage at 7<sup> o</sup>C and 90-95% RH in different periods, i.e., 7, 14,21 and 28 days. Results show that there were significant increases in vegetative growth characters, photosynthetic pigments, yield and it's components as well as some chemical constituents of pods as aresult of snap bean seeds inoculation with AMF plus application with soil yeast around root zone by using hand sprayer as compared to other treatments.<br /> Spraying snap bean plants with pigeon manure tea at 10g/L recorded maximum values of vegetative growth characters, photosynthetic pigments, yield and it's components as well as chemical constituents of pods followed by humic acid at 3cm<sup>3</sup>/L as compared to the control.<br /> The interaction treatment between dual inoculation with AMF and soil yeast and foliar spray with pigeon manure tea gave the highest values of vegetative growth characters, photosynthetic pigments, yield and it's components as well as chemical constituents of pods followed by the interaction treatment between dual inoculation with AMF and soil yeast and foliar spray with humic acid. <em> </em> <br /> Generally, quality parameters of snap bean pods during cold storage at 7<sup> o</sup>C and 90-95 RH indicate that weight loss was increased, while dry matter, total carbohydrates and crude protein percentage in snap bean pods were decreased as the storage period prolonged up to 28 days from the beginning of storage period. Green pods obtained from plants treating by dual inoculation with AMF and soil yeast and sprayed with pigeon manure tea or humic acid and stored at 7<sup> o</sup>C and 90-95 RH for 21 days was the best interaction treatment recorded the lowest values of weight loss and the best values of dry matter, total carbohydrates and crude protein percentage.
