Two open field experiments were conducted during summer seasons of 2019 and 2020, in a private farm at Abou El-Matamer district, Behiera Governorate, Egypt. Certified imported potato seeds of 'Cara' cv. were used after splitting-up. Cut seedy explants (ca. 40 g) contain two eyes each were planted at 0.80 m wide and 0.20 m apart between hills, using four concentrations of synthetic NAA auxin (control, 25, 50, and 100 mg l-1) and four concentrations of the synthetic cytokinin BA (control, 25, 50, and 100 mg l-1) were foliar applied separately and in combinations. Control plants were sprayed with distilled water. The effects of both variables and their combinations were investigated on the vegetative growth-related characters, yield and its components, leaves and tubers chemical composition. The obtained results declare, in general, that foliar application treatments of auxin (NAA) and cytokinin as BA alone or in combination to potato plants gave, significantly, the highest average values of both yield and chemical content compare to untreated plants. The combination between 100 mg l-1 NAA plus 100 mg l-1 BA might be considered as an optimal treatment for the production of high yield and good quality of potato plants under the environmental conditions of Behiera Governorate and other similar regions.

The present study was conducted to select cotton stable cultivars with high productivity across various environments. Nine Egyptian cotton cultivars were grown in a split-plot randomized complete block design with three replications consisted of six different environments (2 years × 3 sowing dates) to identify the high yield stability cultivars under these conditions. Pooled analysis of variance for; number of bolls/plant, seed cotton yield and lint yield revealed significant differences due to cultivars, environments and their interactions. Results revealed that the cultivars Dandara and Giza 90 were considered as superior cultivars under different environmental conditions due to their high number of bolls/plant, seed and lint yield traits across different environments when compared with grand mean for these traits beside acceptable stability parameters (bi near to one, S2di non-significant, α stability value not significantly differed from zero and the λ statistic was not significantly differed from one). Therefore, it could be used in breeding programs for development of high yield stable genotypes across environments for future use. Also, principal component analysis (PCA) showed that Dandara and Giza 90 cultivars were located near all studied traits and environments (stable cultivars over different environments). According to our results the two cultivars (Dandara and Giza 90) can be recommended to be uses under a wide range of environmental conditions and use in breeding programs for development of high yield stable genotypes across environments for future use.

Ten yellow maize inbred lines and three testers were top crossed in line × tester scheme in 2019 season. The resulted 30 top crosses with two check hybrids were evaluated at two locations in 2020 growing season to assess mean performance, general and specific combining ability and their interaction with locations as well as elucidate type of gene action. The recorded data were days to 50% silking, plant height, ear height, ear length, ear diameter, No. of rows/ear, No. of kernels/row and grain yield (ardab/fed). The results showed that, the mean squares due to locations (Loc), genotypes (G), crosses (Cr.), G × Loc and Cr. × Loc interactions were significant for all the studied traits. Highly significant differences were observed among the evaluated lines (L), testers (T) and its corresponding hybrids for all traits. non-additive gene action gave an important role in the inheritance of all the studied traits. The inbred lines L2, L4 and L6 showed the best desirable GCA effects for earliness, L6, L7 and L10 for shortness and L4, L5, L6, L7 and L9 for lower ear placement. Whereas the inbreeds L3, L6 and L7 were the best general combiners for grain yield. The crosses L2×T1, L8×T1, L1×T2, L7×T2, L3×T3, L6×T3 and L10×T3 had the best SCA effects for grain yield. The ten inbred lines were classified into three different heterotic groups using HSGCA method. These groups could be used for selecting the best parents for making crosses in maize breeding programs.

Experiments were carried out during two consecutive 2017/2018 and 2018/2019 seasons to measure the influence of various sources of nitrogen fertilizers on enhancing growth and fruiting of Williams banana plants grown under Qena Governorate, Egypt. Applying 25% of the recommended nitrogen dose along with 25 to 50% organic-N enriched with EM as a bio-form at 50 or 25% were effective in enhancing all growth aspects, production and fruit quality compared to the control. Using combination of three forms of nitrogen were more favorable than using mineral-N alone.Therefore, it could be concluded that using three forms of nitrogen fertilizers get high yield with good fruit quality of Williams bananas. In addition, it reduces the cost of production and environmental pollution, due to excess of chemical fertilizers..

study the effect of some treatments shows that sunburned berries % was significantly reduced with spraying Kaolin at 4 %, Purshade at 4%, Screen Duo at 12 cm3/L, GA3 at 10 ppm+ 2 % Urea was investigated on the control of sunburn effects, berry temperature and yield quality of red globe grapevines grown under the Egyptian hot conditions during 2019 and 2020 seasons. The vines received three sprays of Kaolin, purshade and Screen Duo at (first-June, mid-June and mid-July), while GA3 and Urea were sprayed twice at two weeks after fruit setting and 30 days later for both seasons. Results showed that all treatments reduced berry temperature. The application of Screen Duo surpassed the application of Kaolin, Purshade and GA3 plus Urea in this respect as it was one of the most effective techniques in controlling. However, spraying in all treatments effectively reduced sunburned berries %, total acidity and improved yield quality, cluster weight, total soluble solids, anthocyanin and reducing sugar. Treatment with Screen Duo at 12 cm3/L+ GA3 at 10 ppm+ 2 % Urea gave the best results concerning Growth parameters, yield, cluster weight, cluster length, cluster width, sunburns and some physical and chemical properties of berries grapes. Control treatment gave the lowest value concerning all parameters in two seasons.

Pot experiments were conducted during two successive seasons of 2019 and 2020 at the Fac. of Agric., Minia Univ. to investigate effects of four application rates of compost (0, 1, 2 and 3%) (w/w) and six treatments of bio-fertilizers and/or mineral NPK fertilization (control, Azotobacter chroococcum + Bacillus circulans, Azotobacter chroococcum + Bacillus megaterium, mixture of bio., mixture of bio. + 75% NPK and 100% NPK) on vegetative criteria, accumulation of bioactive compounds (phenolic compounds and flavonoids) through improving plant's secondary metabolism and antimicrobial activity of methanolic and ethanolic extracts of Populus alba. All compost treatments significantly improved all transplant vegetative growth parameters such as plant height, diameter, aerial part fresh and dry weights, main root length and roots fresh and dry weights, as well as, total chlorophylls and NPK% as compared to control. Biofertilizers and/or mineral NPK fertilization treatments significantly increased all the previous traits, the mixture of three species of bacteria plus 75% NPK followed by mineral full dose of NPK treatments were the most effective than other used treatments. The highest values were obtained when Populus alba transplants were grown in sandy soil contained 3% compost plus inoculation with three species of bacteria plus 75% NPK or compost at 3% plus 100 % NPK and these two treatments give the highest values of phenolic compounds in the methanolic and ethanolic extracts. This research confirmed that poplar is a promising wooden tree to be grown on sandy soils for timber production in Egypt, woody products and bioactive compounds.

Eight exotic colored rice lines and four testers were crossed in line x tester. The resulted 32 F1 hybrids along with their parents were evaluated in a randomized complete block design (RCBD) with three replications at the Experimental Farm of Rice Research Department, Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt during2019 and 2020 growing season, to assess mean performance, general (GCA) and specific (SCA) combining ability as well as identify type of gene action controlling the inheritance of the studied traits. The non-additive gene effects had an important role in the inheritance of all the studied traits more than the additive gene effects. The parental lines Dullar, Black Rice and IRBLKM-TS-[CO] were identified as a good combiners for earliness and KWANG CHANG Ai, Black Rice and Sakha 101 for shortness. Whereas, parental lines: Dullar, Red Rice, IRBLKM-TS-[CO], IRBLTA- CT and Sakha 108 were the best general combiners for grain yield and its components. The hybrid combinations Dullar x Giza 178, Red Rice x Giza 178, B40 x Giza 178, KWANG CHANG Ai x Sakha 108, Dullar x Giza 177 and IRBLTA-CT2 x Sakha 108 had the best SCA effects for grain yield as well as one or more of its components. Moreover, the hybrids Red Rice x Giza 178, IR71567-108-1-2 x Giza177 and B40 x Sakha108 recorded the highest value in Fe and Zn concentrations in grains. These hybrids could be used for improving grain yield and micronutrient content particularly Fe and Zn in rice breeding programs.

Breeding for produced new rice varieties with good grain quality especially for low amylose content has become one of the most important goals in plant breeding programmes. In this experiment, three rice genotypes(Giza178, Giza175 and IR64) were used as a perants to study the inheritance amylose content, heritabilityand genetic parameters for grain yield per plant, 1000-grains weight, grain length, grain shape, hulling%, milling%, head rice% and gelatinization temperature characters. A randomized complete block design (RCBD) was used with three replications for six generations viz., P1, P2, F1, F2, BCP1 and BCP2 of a cross between Giza 178 (low amylose content) x Giza 175 (high amylose content) (cross I) and Giza178 (low amylose content) x IR64 (intermediate amylose content) (cross II) were used for the study. The results showed that the F1 plants of cross I gave intermediate amylose content in the endosperm 22.58%, while, the amylose content of F2 plants varied from 13.10 to 35%. and classified into two categories, i.e. 13.10-19 % and 20.50 -35 %.. These results indicated that high amylose content was incompletely dominant over low amylose. Cross II (Giza 178/IR64) low amylose content parent (Giza178) and intermediate amylose parent (IR64) gave 19.84% amylose content in F1 plants, while in F2 grains amylose values ranged from9.5 to 24.1. The plants could be classified into 3 categories. Category 1 with 9.5% - 11% a, category 2 (14.5-19.05%) and Category 3 (21.1-24.1%). Selection for intermediary segregates would be ineffective because the dosage effects would dissipate in further generations.

A reliable micropropagation protocol was developed for Red Maple tree for the first time in Iraqi Kurdistan Region to introduce this newly entered species to the local community. At initiation stage, healthy and vigorous cultures were established following a critical disinfestation protocol by bleach (Sodium hypochlorite) at 2.5 % for 20 minutes. The obtained results show that shoots multiplication was successfully enhanced by recording the highest number of shoots and leaves per explant when 0.5 mg.L-l BA was added to WPM by recording 2.08 shoots/ explant and 13.7 leaves/ explant, respectively. Whereas, the longest shoots were obtained when 1.5 mg.L-l BA was added by reaching 1.86 cm. For root formation, IBA was more effective than NAA by giving the best rooting parameters. The highest number of roots per explant (3.00 roots/ explant), the longest roots (5.87 cm) and the highest rooting percentage (100%) were obtained when 0.1 mg.L-l IBA was added to WPM. The half-light intensity (50 feet/ candle) showed better rooting abilities of microshoots than full light intensity conditions (100 feet/ candle) by raising the number of roots from 3.00 to 4.00 roots/ explants, increasing the mean length of roots from 5.87 cm to 6.37 cm when the comparing between the highest rooting parameters at full light illumination. A 100% survival rate was achieved from the acclimatized plantlets in the greenhouse conditions without any abnormal morphological characteristics. It can be recommended that this important plant can be propagated by tissue culture technique toward mass production in the local area.

Potassium plays a pivotal role in improving potato quality and yield. Field experiment was conducted during fall seasons of 2018/2019 and 2019/2020 at the experimental facilities of Minia University, Egypt, in order to study effects of different organic and inorganic sources of potassium (Potassium Sulfate - Potassium Humate - Potassium Nitrate - Potassium Silicate) on growth and yield performance of potato cultivars of (Lady Balfour and Cara). After 75 days from planting, maximum plant height and number of branches was obtained with cultivar Lady Balfour fertilized with potassium humate. Use of potassium humate with Lady Balfour gave superlative results in terms of length of branches, number of stems and weight of branches, while the leaf area was increased in the Lady Balfour with potassium silicate treatment. The greatest amount of tubers/plant in both seasons were achieved by Cara fertilized with potassium silicate, while the weight of tubers/plant was recorded by Lady Balfour with potassium humate treatment in the second season. The greatest tuber yields for both seasons were achieved by Cara with potassium silicate and Lady Balfour with potassium humate. Tuber’s texture, TSS and contents of chlorophyll a, b and carotene were higher with Cara cultivar fertilized potassium humate and potassium silicate. The results of experiment showed that the highest contents of nitrogen, phosphorous and potassium in potatoes leaves obtained by humic acid with both cultivars. Positive impacts of potassium humate followed by potassium silicate over other examined potassium sources on potato growth and quality were confirmed.

The experiments were carried out during 2018/2019 and 2019/2020 seasons. Greenhouse experiments carried out at Department of Plant pathology, Faculty of Agriculture, Ain Shams University. Field experiments were carried out at Kaha Vegetable Research Farm, Kaliobia Governorate. Compared with untreated infected garlic plants Sids-40 cultivar, all foliar applications with aqueous extracts of each of henna (Lawsonia inermis), licorice (Glycyrrhiza glabra), rosemary (Salvia rosmarinus), mixtures of them at levels 5% and 10% for each extract or Ridomil plus (2.5g /L) showed significant decrease in purple blotch severity and resulted in significant increases in phenolic compounds, oxidative enzymes activity i.e., CAT, POD and PPO during two growing seasons. However, significant decreases of proline content were resulted in the treated infected leaves during both seasons. Spraying with licorice and mixtures of extracts at5% and10% resulted the highest significant decreases of disease severity under both greenhouse and field conditions. Also, licorice at10% exhibited the highest values of plant length, fresh and dry weight of plants, values of bulb weight, total yield at harvest and after curing. Mycelial inhibition test proved that all extracts have an inhibitory effect on mycelial growth of A. porri and licorice extract exhibited the highest effect, even still lower than Ridomil Plus effect. It can be concluded that all aqueous extracts tested were able to reduce the disease severity as a result of either direct microbial growth inhibition or induction of garlic plant resistance against A. porri, thus as well was associated with improved plant growth parameters and garlic yield.

A field experiment was carried out to investigate the effect of organic and inorganic fertilizers and their combinations under different irrigation intervals on yield and its attributes of the Giza178 rice cultivar, as well as, the availability of some micronutrients in the soil. Irrigation treatments were continuous flooding (CF), continuous saturation (CS), irrigation every 6 days (E6D), every 9 days (E9D) and every 12 days (E12D), while the fertilizer treatments were control (without fertilizer), 5t cattle manure ha-1 (CM), 5t compost ha-1 (C), 5t cattle manure +110 kg N ha-1 (CM+110N), 5t compost +110 kg N ha-1 (C+110N) and the recommended N rate of 165 kg N ha-1 (165N). Prolonged irrigation intervals of more than 6 days substantially decreased the yield and its attributes, Fe and Mn concentration in the soil in both seasons. The opposite was true for Zn concentration. Fertilizer sources containing chemical N (165N) alone or 110N with C or CM significantly surpassed each of the two organic sources alone in yield and yield attributes in the two seasons. The application of C+110N fertilizer with irrigation E6D was statistically at par with the recommended interaction (CF irrigation X 165N fertilizer) in yield and its attributes. The total amount of irrigation water applied was decreased by prolonging the irrigation interval. The inverse was true for water saved and water productivity in kg grains m-3. Application of C+110N fertilizer with irrigation E6D recorded the highest water productivity and saved water > 3000 m3 in the two seasons.
