Abstract This study was carried out during 2011 and 2012 seasons on "Manfalouty" pomegranate cv. grown at the experimental orchard of Pomology Department, Faculty of Agriculture, Assiut University. The objectives of this study were examining the effects of pre-harvest spray with CaCl2 (4%) and GA3 (100 ppm) as well as post-harvest treatments with jasmine oil (2.5 cm3/L), olive oil (2.5 cm3/L), fiber gard (20 cm3/L) and wrapping individually fruit with food polyolefin stretch as an improving effect in physicochemical characteristics of "Manfalouty" pomegranate cv. during storage under room temperature (22+5°C). The experiments were set up on split-plot arrangements in complete randomized block design (CRBD), with three replicates, 20 fruits each. According to the obtained results of this study, it could be deduced that pre-harvest spray with GA3 (100 ppm) gave in general, the best results on improving physical and chemical characteristics, followed by CaCl2 (4%) during the two growth seasons, as well as wrapping individually fruits with food polyolefin stretch gave the best quality during shelf-life period, followed by dipping fruits in both jasmine oil or olive oil and fiber gard during fruit storage under room temperature. Therefore, the authors recommended with wrapping individually fruits to keep fruits with good quality during fruit storage under room temperature.

ABSTRACT The effects of spraying barley seed sprout and/ or potassium silicate each at 0.025 to 0.1% on fruiting of Red Globe grapevines was examine during 2015 and 2016 seasons. The selected vines were sprayed three times with such two stimulants. Barley seed sprout and potassium silicate each at 0.025 to 0.1% single and combined applications improved growth aspects, leaf pigments, some nutrients, berry setting %, yield and fruit quality compared to the control treatment. Using combined applications was superior to using each alone.The effect on these parameters depended on increasing concentrations. Spraying a mixture of barley seed sprout and potassium silicate three times each at 0.05% improved yield and quality of Red Globe grapevines under Minia conditions

Abstract The effects of GA3 and CPPU on fruiting of Seewy date palm grown at the Experimental Orchard, Faculty of Agriculture, Assiut University, Egypt were investigated during 2013, 2014 and 2015 seasons. All treatments were sprayed after two or eight weeks of pollination. The experiment was set up in a complete randomized block design with five replications of one bunch each. The obtained results could be summarized as follow: - Fruit set and fruit retention percentage were significantly decreased due to spray GA3 at 50 ppm after two weeks of pollination followed by GA3 or CPPU after eight weeks of pollination compared to unsprayed one (control). - Spraying the bunch with GA3 twice, once at 50 ppm after two weeks of pollination followed once GA3 at 75 ppm plus CPPU at 7.5 or 15 ppm after eight weeks of pollination gave the highest fruit weight, flesh percentage and dimention of fruits compared to unsprayed ones. - Spraying GA3 and CPPU significantly improved the chemical fruit properties in terms of the total soluble solids and sugar contents and significantly decreased the total acidity and total soluble tannins percentages compared to unsprayed ones. So, it concluded that spray GA3 at 50 ppm after two weeks of pollination plus either GA3 at 75 ppm and CPPU at 7.5 ppm or GA3 at 75 ppm and CPPU at 15 ppm to obtain the high yield with good quality of Seewy dates. GA3 reduce the fruit retention and consequently increase the fruit weight and size induce increased the yield. CPPU induced an increase in fruit weight and size then get high yield of Seewy dates. Thus, spraying the bunches of Seewy date palm with GA3 and CPPU had get the heaviest yield with improvement the physical and tested chemical fruit properties

Abstract This study was carried out during 2014 and 2015 seasons in a private orchard of Jojoba located at Mout, El-Dakhla, New Valley Governorate to examine the effects of GA3 (25, 50 and 100 ppm), camphor oil (1.5, 3.0 and 4.5 cm3/L), effective microorganisms (EM1, 3, 6 and 9 cm3/L), glauconite compound (250 and 500 g/shrub) and a mixture of GA3 (50 ppm) with the afromentioned concentrations of camphor oil on vegetative growth, yield/shrub and Jojoba seed characteristics. The treatments were conducted at start of Jojoba blooming (the 1st application time), and the 2nd application was achieved 3 weeks after fruit set, except the glauconite was applied 3 weeks before Jojoba blooming. The experiment was conducted in randomized complete block design (RCBD) with 3 replicates, 2 shrubs each. According to the obtained results of this study, it could be deduced that all treatments improved the vegetative growth, yield and seed quality. Concerning oil weight/100 seeds and oil % in seeds treatment with mixture of GA3 (50 ppm) and camphor oil (1.5 or 3.0 cm3/L) gave the best results during the two studied seasons. Therefore, for improving yield and seed quality it could be recommended spray jojoba a mixture of GA3 (50 ppm) plus camphor oil at 1.5 or 3.0 cm3/L under the condition of this study.

ABSTRACT During 2014 and 2015 seasons, Early Sweet grapevines were fertilized with the recommended rate of N via 100% mineral N, 100% plant compost (p c) enriched or not with Spirulina platensis algae(S p a) as well as via 25 to 75% inorganic N plus 25 to 75% plant compost with or without Spirulina platensis algae. The merit was replacing inorganic N partially by using plant compost enriched or not with Spirulina platensis algae. Growth characteristics, leaf pigments, N, P, and K, yield, quality of the berries and juice content of nitrite were investigated. Using N as 50% inorganic N + 50% plant compost enriched with Spirulina platensis at 10 ml/ vine improved growth characteristics, yield, cluster weight and quality of the berries. There was a gradual effect on leaf pigments, N, P, K and fruit quality with reducing the percentages of inorganic N from 100 to 0.0% and increasing percentages of plant compost with or without the algae form 0.0 to 100%. Juice content of nitrite and shot berries % gradually declined with reducing inorganic N and increasing plant compost enriched or not with Spirulina platensis algae. Using plant compost enriched with Spirulina platensis was more favorable than using plant compost alone in this respect. A pronounced promotion on yield and fruit quality of Early Sweet cultivar was observed when the vines were subjected to the recommended rate of N as 50% inorganic N plus 50% plant compost enriched with Spirulina platensis algae at 10 ml/ vine. ** Spirulina platensis algae (S p a) - plant compost (p c)
