Effect of Deficit Irrigation and Planting Method on Maize Plants under Middle Delta Conditions of Egypt
Two field experiments were carried out at El-Gemmeiza Agricultural Research Station Farm, Egypt, during 2017 and 2018 summer seasons to study the effect of soil water deficit and the planting method on maize plant under Middle Delta conditions of Egypt. Irrigation at 65% available soil moisture depletion (AVSMD) did not significantly decrease chlorophyll content, dry matter (DM), leaf area index (LAI), crop growth rate (CGR), relative water content (RWC), osmotic potential (OP), ear length, ear diameter, rows per ear, kernels per row,100-kernel weight and grain yield. 50 % irrigation treatment decreased crop water productivity (CWP) by 9.93 % across the two seasons compared to irrigation at 80 % AVSMD. Irrigation at 80 % of AVSMD increased drought sensitivity (YR/ SD) and the drought susceptibility index (S) and CWP in both seasons. The reduction in WCU due to irrigation at 65 % of AVSMD reached 19.34 to 20.30 % and the improvement in CWP was 15.42 to 14.37 % compared to the irrigation at 50 % (control) in both seasons, respectively. Sowing maize plants on beds140 cm apart on both sides of beds and the distance between the hills was 25 cm (24000 plants per feddan) resulted in the highest chlorophyll content, DM, LAI, CGR, RWC, ear height, ear length, 100-kernel weight and grain yield in the two seasons, This treatment decreased YR/SD and S. Decreasing YR/SD and S. such decreases were accompanied with increasing CWP. It can be recommend that sowing maize plants on beds140 cm apart on both sides of beds, and the distance between hills 25 cm and irrigation at 65 % of AVSMD decreased WCU and improved CWP, in addition this treatment did not significantly decrease yield and its components and attained the lowest YR/S and S values.

Effect of some Stimulants on Productivity of Pea (Pisum sativum L.) under High Temperature Stress Conditions
Two filed experiment were conducted at El- Baramoon Experimental Farm during 2016/2017 and 2017/2018 seasons to study effect of sowing dates and some growth stimulants on growth, yield and its component and seed quality of pea. The experiment was laid-out in a split-plot design with three replications. Sowing on 1st week of Sept. recorded the best results of plant height, number of leaves, fresh and dry weights of plant, N, P and K contents in leaves, pods number/plant, yield per plant and feddan than. Treated pea plants with NPK at 50 % of RR + humic acid + magnetic iron recorded highest values of plant height, number of leaves, total fresh and dry weights/plant, yield per plant fed in the both seasons and 100-seed weight in 2nd season. The N, P and K % in leaves were obtained with NPK at 50 % RR + humic acid + proline. Sowing on 1st week of Sept. and fertilizing with NPK at 50 % RR + humic acid + magnetic iron increased plant height, number of leaves, total fresh and dry weights/plant, yield per plant fed in both seasons and 100 seed weight in the 2nd season. While, sowing on 1st week of Feb. and spraying with proline amino increased proline content and oxides enzyme activity. Meanwhile, sowing on 1st week of Sept. and fertilizing with NPK at 50 % RR+ humic acid + proline gave the highest values of N, K and lowest values of proline content and oxides enzyme.

Effect of Some Factors Affecting Selected Carob Strain (Ceratonia siliqua L.) Propagation by Grafting
This study was carried out in the experimental orchard of Horticultural Research Institute, Agriculture Research Center, Giza Governorate, Egypt through 2017 and 2018 seasons. The main aim was to find out the most reliable carob (Ceratonia siliqua L.) grafting technique (cleft with apical and axillary buds, saddle with apical and axillary buds, cleft with axillary buds and saddle with axillary buds) and the suitable grafting date (15th February, 15th March or 15th April). Results showed that cleft with axillary buds grafting proved to be the best technique regarding modified success percentage, leaves number, scion and rootstock diameters. Cleft with apical and axillary buds grafting technique recorded the highest modified survival percentage and vegetative growth length values. February was the best grafting date concerning vegetative growth length, leaves and sprouted shoots numbers. Modified survival percentage and grafting union diameter were improved in March. Using saddle with axillary buds grafting in February and March produced the maximum sprouted shoots number, whereas using it in March recorded higher grafting union diameter value. Vegetative growth length and modified survival percentage were improved using cleft with apical and axillary buds grafting technique in February and March, respectively. Both cleft with axillary buds and with apical and axillary buds grafting techniques were the best regarding grafting union examination. It can be recommended that, carob can be vegetatively propagated by using either cleft with axillary buds or with apical and axillary buds grafting techniques. Also, grafting carob can be done in February or March.

Morphological Identification of some Faba Bean Genotypes
A study of 8 promising lines (from G1-G8) and 4 varieties (Misr1, Giza 843, Roomy, and Peter15) of faba bean genotypes. Was carried out at Sakha Agricultural Research Station, ARC, Kafr El-Shikh Governorate during the winter seasons of 2017/2018 and 2018/2019. Agro- morphological variability based on the internationally recognized descriptors of the International Union for Protection of new Varieties (UPOV, 2015) was used to characterize these genotypes. The results showed that G1 had broad leaflet, two pods/ node, strong curved pod and highest weight of 100 seeds. The angle between pod and the main axis in G2 was perpendicular. Narrow leaflet and pod curvature was absent in G4. Flower ground color was light purple, strong curved pod in G5. Strong intensity of stem anthocyanin coloration in G6, with beige ground flower color and with angles on its dry seed shape. Misr1 recorded the shortest genotype. G8 identified with longest leaflet and was the highest genotype. Each pod and seed of Roomy genotype had the maximum length and width with elongated flattened seed shape. Giza 843 was ovate leaflet shape. Peter15 had two pods/node but ranked the short pods, lowest 100 seed weight short and narrow seed. The morphological variation of these genotypes was useful and can allow breeders identify faba bean plants with desirable characteristics that can be used in breeding programs.

Response of some Bread Wheat Genotypes to Less Irrigation Water
This study was performed at Sakha Agricultural Research Station, Kafer El-Sheikh, Egypt, in 2014/2015 and 2015/2016 seasons under normal (five irrigation) and reduced irrigation (only one irrigation after planting one) regimes. Eighteen bread wheat genotypes were used to study the agronomic and morpho-physiological characters and tolerance indices to distinguish wheat high yielding genotypes under reduced irrigation. The used genotypes were evaluated using randomized complete block design. The results revealed that reduced irrigation caused noticeable reduction in earliness, yield and yield components, harvest index and morpho-physiological in both growing seasons except 1000 kernels weight. Lines 3, 4 and 5 were the earliest ones for earliness characters and could be used in breeding program for earliness. It is obvious that lines 1 and 9 recorded the maximum values for most studied characters, especially, grain yield. Lines 1, 4, 6, 9, 10 and cultivar Misr 1, Giza 171 and shandweel1 had the highest relative water content and rate of water loss in both seasons. Also, Line 1 and Line 9 recorded the highest values for water use efficiency. Based on drought tolerance indices of mean productivity, geometric mean of productivity, stress tolerance index, yield index, harmonic mean and modified stress tolerance index, Line 1 and Line 9 were identified as suitable genotypes under well-watered and water deficit conditions. Misr 1, Misr 2, Giza 171, Lines 2, 6, 8, 10, 11, 12 and 13 were moderate for drought tolerance index and the others wheat genotypes were sensitive for water deficit.

Physical and Mechanical Characterization of Three Egyptian Woody Species
Currently, there is lack of data provided in the literature regarding the wood quality of locally grown timber trees. It is known that the wood quality varies greatly from one geographical area to another depending on the growth conditions and environmental factors. Therefore, this study aimed to characterize the wood quality of three hardwoods species; Dalbergia sissoo Roxb. (irrigated with treated wastewater), Morus nigra, and Ficus retusa L. grown in Egypt in order to find the possible utiliz

Improving Vegetative and Flowering Characteristics of Kalanchoe by Using some Plant Growth Retardants
The objective of this investigation was to study the effects of cycocel (CCC) and paclobutrazol (PBZ) on Kalanchoe blossfeldiana, L. to produce plants more compact, shorter, with a plurality of branches and inflorescences, flowering earlier, and to be more suitable as a pot plant. Different concentrations of CCC at 1000, 2000, and 3000 ppm and PBZ 50, 100, and 150 ppm were applied as foliar spray for once (after 45 days) or twice (after 45 and 60 days from planting). All treated plants were shorter with profuse branches specially the ones which have been treated with PBZ at 150 ppm twice (6.00 branches/ plant), and by the same treatment achieved the maximum number of inflorescences as it recorded 5.00 inflorescences/ plant. Sprayed plants with PBZ at 150 ppm twice gave the minimum number (125.33) of days to flowering. The total chlorophyll and carbohydrates content were increased in all sprayed plants, as it was 0.679 mg/ g FW for chlorophyll (PBZ 100 ppm twice) and 207.07 mg/ g DW for carbohydrates (PBZ 150 ppm twice). For compressed Kalanchoe plants with dark green leaves, abundant branches, abundant blooms and early blooms, paclobutrazol may be recommended at 150 ppm twice.
