Effect of Carbon Source in Woody Plant Medium with Different Salt Strengths on Oak (Quercus aegilops L.) Micropropagation
This study aimed to test the influence of different carbon sources in woody plant medium with various salt strengths on in vitro propagation of oak. The results showed that, sucrose was better than the other sugars by giving the highest shoots number, length of shoots and leaves number per explant (2.05, 1.30 and 17.67 respectively). The highest shoots number per explant was achieved when 45 gl-l of glucose and 30 gl-l of sucrose were added by giving 3.44 and 3.33 shoots/ explant respectively followed by 45 gl-l sucrose and 30 gl-l of glucose by giving 2.67 and 2.11 shoots/ explant respectively. On the other hand, full Woody Plant Medium salt strength gave the best multiplication results while the quarter Woody Plant Medium salts strength gave the lowest values. The highest roots number per explant was achieved when full salts strength was used which gave 5.40 roots followed by half salts strength with 2.60 roots then quarter salts strength by 0.30 root which was the lowest parameter. Furthermore, the highest rooting percentage was acquired in both full and half salts strength which was 100% and the lowest rooting rate was 30% in quarter salts strength. Sucrose was the best carbon source by giving the best root system and giving the highest rooting percentage (100%) followed by glucose (60%). The produced oak plantlets were successfully hardened and acclimatized to be transferred to the permanent field in the greenhouse with a success reached 85%.

Effectiveness of Fungal Disinfectants under Various Seed Drying Treatments on Physiological Seed, Quality and Field Performance of Wheat Seedlings
Laboratory and field experiments were conducted to estimate the effect of fungal disinfectant (Tendro 40% FS) and seed drying treatments and their interaction on physiological quality and field performance of wheat seed. Seeds were exhibited to the fungal disinfectant concentrations i.e., 5cm3kg-1, 3cm3kg-1 and 7cm3kg-1 seed in addition to undressed seed as control treatment, while the second factor was seed drying treatments i.e., natural drying (indirect sunlight), interrupted drying (hot air dryer) and rapid drying (oven dryer). Factorial experiment in RCD and RCBD with 4 replicates were set to perform laboratory and field experiments, respectively. All fungal disinfectant concentrations significantly enhanced the germination indices over the untreated seed, while 5cm3kg-1 treatment showed the greatest increase upon control of G% (5.4%), FE% (7.4%), SDW (40%) and (23%), SVI (46.2%) and (27.2%) of laboratory and field performance, respectively. SMC ranged from 11.18%, 11.07% and 11.0% for natural, interrupted and rapid drying treatments, respectively. More, rapid drying recorded the highest loss of water in the shortest period of drying which was 4h(4h×1day), followed by interrupted and natural drying treatments which recorded 8h(4h×2days) and 24h(6h×4days), respectively. Moreover, the interrupted drying significantly permits the higher values of G% (93.5%), FE% (87.8%), SDW (0.20g) and (0.17g) and SVI (0.19) and (0.15) of laboratory and field performance, respectively. Finally, the interaction treatments showed no significant effect but on MGTday trait, more treatment 5cm3kg-1×8h of interrupted drying showed the highest seed physiological and field performance values upon the other interaction treatments.

Comparative Study on some Pure Successive Maintained Nuclei (Foundation Seed) of Giza 95 Cotton Cultivar and its Corresponding Handled one’s in General Cultivation.
Four successive pure maintained nuclei (N) and four handled farmer's seeds (F) of Giza 95 Egyptian cotton cultivar were used to evaluate the changements that might occur in earliness, yield ,fiber quality and genetic constitution of the cultivar after handling the seeds by the farmers. Two field experiments were carried out at Sids Agric. Res. Station, throughout growing seasons 2017 and 2018. Genotypes mean squares were significant and/or highly significant for seed cotton yield, lint yield, earliness index and yarn strength in both seasons and combined analysis. The greatest amount of differences among the studied strains were mainly due to the variances among the farmer's seeds and the interaction (N vs F), for these characters indicating farmer seeds might get genetic imperfection due to mechanical mixture or out-crossing by off-type plants. The interactions of genotypes by environments (G x E) were insignificant for all studied characters except boll weight and fiber fineness. Regarding mean performances, the results indicated that the pure nuclei strains surpassed the farmer's ones for most studied traits. The older farmer's strains (G.95/2014) exhibited lower mean performance estimates for most studied yield traits over the two environments and it’s combined data. Also, nuclei seeds gave the best performances for most fiber properties compared with the farmer's ones. Seed cotton yield in both nuclei and farmer's strains was positively and significantly related with earliness index and fiber fineness suggested that any changes when appear in these characters may be correlate with decrease of seed cotton yield or any deterioration appeared.

Optimizing Sowing Date and Nitrogen Fertilizer Level for the New Rice Variety Sakha Super 300
A field trial was performed in Randomized Complete Block Design (RCBD) with three replications at the Experimental Farm of Sakha Agricultural Research Station, Kafr ELSheikh, Egypt, during 2018 and 2019 rice growing seasons, to investigate the effect of three sowing dates (May 10th, June 1st and June 20th) and four levels of nitrogen fertilizer (0, 55, 110 and 165 kg N/ha) on the productivity of Sakha Super 300 variety. The results showed that the sowing date June 1st produced the highest grain yield 10.67 and 10.71 t ha-1 in both seasons. Nitrogen level of 165 kg N ha-1 produced the highest grain yield 10.50 and 10.45 t ha-1 without any significant difference with level of 110 kg N ha-1 in 2018 and 2019 seasons. The interaction between sowing dates and nitrogen levels was highly significant for number of panicles hill-1, panicle length, number of filled grains panicle-1, unfilled grains percentage and 1000-grain weight, as well as grain and straw yield and harvest index in both seasons. Interaction results showed that, the first sowing date (May 10th) with nitrogen level of 110 kg N ha-1 gave the highest grain yield 10.91 and 10.79 t ha-1. On the other hand the second sowing date (June 1st) with nitrogen level of 165 kg N ha-1 gave the highest grain yield 12.03 and 11.92 t ha-1 in 2018 and 2019 seasons. The highest values of accumulated growing degree days (GDD) and photo thermal units (PTU) were recorded when plants sown on May 10th. On the other hand the maximums heat use efficiency (HUE) was achieved when Sakha Super 300 sown on 1st June with application of 165 Kg N ha-1 in both seasons.

Effect of Natural Potassium Resource (K2O 10 %) with Bio-fertilizer on Performance of Date Palms Cv. Zaghloul
Performance of the palm trees and fruit quality of cv. Zaghloul under different levels of natural potassium (NP) resource (K2O 10 %) individually or in combination with potassium soluble bacteria (KSB) were studied in the 2016 and 2017 seasons. Treatments included 3, 6 or 9 kg/palm per year of NP either individually or in combination with KSB on ‘Zaghloul’ date palms grown on sandy soil with 7 meters apart under surface irrigation system; whereas, palms received 2 kg/palm per year potassium sulfate (50% K) served as the control. The results revealed that 9 kg of NP in combination with KSB enhanced vegetative growth, pinnae mineral content, chlorophyll, bunch weight, palm yield and fruit quality than other applications or control palms. Therefore it is recommended to use 9 kg of NP in combination with KSB/palm/year for increasing yield of Zaghlol date palms and improving fruit quality.

Influence of Irrigation Treatments and Humic Acid (HA) Application on Vegetative Growth, Yield, Tuber Quality Water Requirements and Water Utilization Efficiency (WUE) of Potato Plants.
The present investigation were carried out in the two successive summer growing seasons 2018 and 2019 on potato plant, CV. Sponta, at South El- Tahrir district, newly reclaimed sandy soils at the experimental station farm, Horticulture Research station Beheira Governorate to study the influence of irrigation treatments and humic acid (HA) application at different growth stages on vegetative growth, yield potential, tuber quality, water requirements and water utilization efficiency (WUtE) of potato plants. Nine irrigation treatments were applied at three periods, (S1) vegetative growth, (S2) tuber formation and (S3) tuber bulking. Results revealed that there were significant effects due to the irrigation and humic acid treatments and their interactions on potato production in both growing seasons. T1 irrigation treatment gave the mean highest values of vegetative growth traits (plant height, number of branches, fresh and dry weight of plant, yield/plant, and number of tubers plant-1, average tuber weight, yield/feddan, and tuber diameter). Application of humic acid (HA) resulted in improving vegetative growth characters, in both seasons. Water stress treatments at S1 generated the lowest mean values of all vegetative growth characters, which illustrated that this stage is sensitive to water stress treatments. The interaction between irrigation treatments and HA reflected significant differences on the studied vegetative growth parameters. The interaction of T1 treatment and HA application showed superior influence on vegetative growth traits, in both growing seasons. On the other hand, the highest mean values for tuber content of starch were obtained by Ta and HA application.
