Two field experiments were carried out at the Experimental Farm, Faculty of Agriculture (Saba Basha), Alexandria University, Egypt during 2017 and 2018 seasons, to study the effect of mineral, nano- fertilization, in addition to different weed control on growth and yield of sorghum. Split plot design with three replicates was used, where the main plots occupied by weed control treatments(hand hoeing one time before the first irrigation, hand hoeing twice the first one was before the first irrigation and the second one was before the second irrigation, Heraty sowing method, herbicide treatment before planting and herbicide treatment before planting + one hand hoeing), meanwhile, the combination between NPK mineral and NPK nanoparticles fertilizers (100% mineral NPK (240:60:60 kg/ha), 100% nano NPK (5 L/ha) and 50 % mineral NPK + 50 % nano NPK) were distributed at random within the subplots. Each subplot consisted of 5 ridges 3.50 m in length and 60 cm in the width and the plot area was 10.5 m<sup>2</sup>. The results revealed that, the yield and its components of the sorghum hybrid (Horas) were affected by weed control methods, mineral NPK, Nano NPK and their interaction. The highest value of yield characters of sorghum was achieved when applying hand hoeing one time with herbicide with fertilizing by 50% NPK mineral + 50% NPK NPs fertilization, also these treatments reducing the effect of weeds under Alexandria conditions.

About 200 species of bryophytes are currently known from Egypt. The majority are mosses, only 13 species belong to the liverworts while no hornworts exist. Regarding the liverworts, and following simplified methods used by previous workers, 11 out of the 13 species are listed under threatened categories; 6 of them are in the CR category, 4 in the EN category, 1 in the VU category and 2 are considered not threatened. This evaluation documents the situation at the time of collection, i.e. from 1958 to 1999, which is quite a long time, however, it is basic for any future Red Listing of bryophytes in the country.

This work was carried out during two successive seasons (2017 and 2018) to examine the response of ʺCrimson Seedlessʺ grapes to some pre-harvest treatments i.e. jasmonic acid (JA) at (4 and 8) mM/L and grapefruit seed extract (GSE) at (0.5 and 1) mM/L on some berries quality parameters under cold storage and shelf-life conditions. Vines were sprayed in two application times at (25<sup>th</sup> and 30<sup>th</sup> August) during 2017 and 2018, respectively. The non-ionic surfactant Tween-20 at 0.05% (v/v) was added to all treatments to reduce the surface tension and increase the contact angle of sprayed droplets. Results showed that both jasmonic acid and grapefruit seed extract treatments at different concentrations were significantly effective in reducing weight loss, berry decay, berry shatter, and total loss in cluster weight percentages during the cold storage period and shelf life as compared to the control. Also, the previous treatments significantly increased berry firmness, soluble solid content (SSC%), SSC/acid ratio, and total anthocyanin contents, where it was caused a significant decrease in total acidity percentage during the cold storage period and shelf life in comparison with control.<br /> Furthermore, the lowest values of weight loss, berry shatter, berry decay and total loss in cluster weight were founded by JA at 8 mM and GSE at 1 mM at the end of shelf life in comparison with other treatments. It could be concluded that JA at 8 mM and GSE at 1 mM as preharvest treatments are applicable for improving the storability of ʺCrimson Seedlessʺ grapes and maintaining their quality during cold storage and shelf life.

The present study was carried out at Nubaria Region, El- Beheira Governorate, Egypt, during the two summer seasons of 2019 and 2020 to study the effect of foilar application of salicylic (SA) and ascorbic acids (ASA) on yield and quality of soybean <em>cv.</em> Giza 111 under drip irrigation. This experiment was laid out in the factorial experiment (two factors) in randomized complete blocks design (RCBD) in three replications. The first factor was salicylic acid (SA) concentrations (water = control, 500, 1000, and 1500 ppm), while the second factor was ascorbic acid (ASA) concentration (water = control, 500, 1000 and 1500 ppm) in both seasons. The obtained results showed that foliar application of salicylic acid (SA) and ascorbic acid (ASA) significantly affected plant height (cm), number of branches/plant, number of pods/plant, 100- seed weight (g , seed yield (kg/fed), straw yield (kg/fed), biological yield (kg/fed), harvest index (%), and oil content (%) in the two seasons, whereas increasing of SA and ASA from 500 up to 1500 ppm increased all the studied characters as compared with the control treatments (water spray) in both seasons. The interaction between the foliar application of SA and ASA concentration was significant on all the studied characters in both seasons, where using 1500 or 1000 ppm SA/fed + 500 or 1000 ppm ASA achieved the highest mean values of all the studied characters in the two cropping seasons in drip water irrigation under the study conditions.

The present study was carried out at Nubaria, El-Beheira Governorate, Egypt, during the two summer seasons of 2018 and 2019 to study the effect of foilar application of salicylic rates on yield and quality of some soybean varieties under drip irrigation. This experiment was laid out in a split-plot system with three replications in both seasons. The main plots were soybean varieties (Giza111, Giza 22, J350, and J356), while subplot allocated by the number of spray times of salicylic acid (SA) concentration (water = control, once after 30 DAS, twice after 30, and 50 DAS, and three times after 30, 50 and 70 days after sowing=DAS) was in both seasons. The obtained results showed that foliar application of salicylic acid (SA) of the four soybean varieties significantly affected plant height (cm), number of branches/plant, number of pods/plant, 100- seed weight (g), seed yield (kg/fed), straw yield (kg/fed), biological yield (kg/fed), as well as oil content (%), whereas Giza 111 recorded the highest values of the all the study, also increasing of times of foliar application of SA increased the pervious characters comparing with the control treatments (water spray) in both seasons. The interaction between varieties and number of spray times of SA was significant on all the studied characters, where planting Giza 111 with twice foliar application of SA at the rate 1000 ppm recorded the highest ones in the two cropping seasons in drip water irrigation under the study conditions.

The experiment was conducted on Washington navel orange trees grown in sandy soil under a drip irrigation system at El Nubaria, Behera governorate during both experimental seasons of 2018 and 2019 to study the effect of applying a shading net, spraying potassium silicate, and their combination during fruit development to reduce high-temperature stress on fruit drop (%), number of fruits sunscald, number of fruits/ tree, and fruit quality, the experiment followed Randomized Complete Block Design(RCBD). The results showed that, T4 (Shading net (75%) and T7 (Shading net (75 %) + potassium silicate) caused the highest significant increase in shoot length. in the first season, the two shading treatments (T3 and T4) and the three combined treatments (T5, T6, and T7) caused a significant increase in leaf area compared to the control and the rest treatments. In the first season, Treatments (T4, T6, and T7) caused a significant increase in shoot diameter compared to the rest treatments and the control. In the two seasons, control, and the treatments of spray silicate only (one, two, or three times) caused the highest significant percentage of fruit June drop compared to the rest treatments. All treatments caused a significant increase in average fruit weight (g), juice weight (%), and fruit diameter (cm) compared to control. T2 (35% shading net) caused a significant increase in TSS and TA (%) compared to the control and the two shading treatments (65 and 75%). As for vitamin C shading treatments (T2, T3, and T4) did not show any significant differences among them or compared to the control. The highest value of total chlorophyll was obtained from T4 and T7.

Two field experiments were carried out at Etay El-Baroud Station, El-Beheira Governorate, Agricultural Research Center (ARC), Egypt to evaluate the effect of the three irrigation intervals and potassium silicate of the maize grown in the 2017 and 2018 seasons. The treatments of the two factors were distributed in a split-plot design in the four replications. Where three irrigation intervals (10, 15, and 20 days) were assigned in main plots, meanwhile the four foliar applications of potassium silicate (once spray at 40 days after sowing), twice sprays at 40 and 60 days after sowing, three sprays at 40, 60 and 80 days after sowing) and control (water spray) were allocated in a subplot in both seasons. The results revealed that irrigation every 15 days gave the highest values of growth of maize. Foliar application three times of K- silicate gave the highest values of growth characters. However, irrigation every 15 days with foliar application of K- silicate at three times recorded the highest values of the most growth characters in both seasons.
