Spraying cucumber plants with amino acids increased significantly early yield and total yield in the first season only and average fruit weight in the second season only while TSS was significantly increased in both seasons. Also, microbial inoculants gave the highest number of fruits/m<sup>2</sup>, average fruit weight; early and total yield /m<sup>2</sup> and TSS in both seasons except average fruit weight in the second season only comparing with the other stimulants. Microbial inoculants gave the lowest value of nitrate concentration of fruits comparing with the other stimulants. The combination effect of stimulants and amino acids seems to increase early and total fruit yield and its components and fruit quality. In this connection using microbial inoculants or EM and amino acids gave the highest values of early and total fruit yield and its components and fruit quality.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36697420160401Pearl Millet (Pennisetum glaucum L.)

S.MofeedOlive and semiarid zone fruits department, Horticulture Research Institute, Agricultural Research Center, Cairo, EgyptJournal Article20190821This investigation was carried out through 2013 and 2014 seasons on three olive cultivars (Picual, Manzanillo and Koroneiki) and their adaptability to different types of soil (Sandy, Calcareous, and Silt-Loam) under Wady El-Natroon conditions, El-Behaira Governorate, Egypt. Trees were fifteen years old, planted at 6 x 6 meters apart under drip irrigation system in a private orchard. The aim of the present study was to test the influence of varioustypes of soil on the vegetative growth, flowering, fruiting, yield, physical characteristics of fruits, stones, fruit moisture content (%) and oil content (%) on the studied olive cultivars (Picual, Manzanillo and Koroneiki) to determine the most adapted cultivars for these soil types . The results were, vegetative growth parameters varied according to type of soil and olive cultivars under study, whereas Picual olive trees cultivated in sandy soil recorded the highest values of tree height and trunk cross section, while other vegetative growth parameters [shoot length (cm), No. of internodes/ m, No. of leaves/m and leaf area (cm<sup>2</sup>)] gave the best values with sandy soil and other cultivars. On the other hand, Koroneiki olive trees cultivated in sandy soil produced the highest fruit set (%), the heaviest yield/tree (in both seasons of the study), the longest inflorescence (in the second season) and the best perfect flowers percentage (when cultivated in sandy and calcareous soil). As for fruit and stone physical characteristics, was no clear trend has been shown the effect of soil types (especially for stone characteristics), whereas it's effect was less than the factor of cultivars. It is worth mention and in contrary with all the previous results, all cultivars produced their best percentage of oil content when cultivated in silt-loam soil compared with the other studied types of soil and Koroneiki cultivar was the best in oil content percentage. Under the same conditions of the present study, it could be concluded that, sandy soil was the best soil type for the studied olive cultivars (Picual, Manzanillo and Koroneiki) followed by calcareous soil. But, regarding to the oil percentage, we can take advantage of the cultivation of olive oil cultivars in silt-loam soil.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36697420160401Alleviation of High Temprature in Cabbage Plants Grown in Summer Season Using Some Nutrients, Antioxidants and Amino Acids As Foliar Application with Cold Water.4334414538510.21608/jpp.2016.45385ENM.

Center, Ministry of Agric., during the two successive seasons (2011/2012) and (2012/2013) to study the effects of irrigation intervals and micronutrients on growth, herb yield, leaves yield, essential oil production and its components of rosemary (<em>Rosmarinus officinalis</em> L.) plant. The results showed that: irrigation interval every 7 days resulted in significant increase in vegetative growth characters as well as essential oil content per plant, but irrigation interval every 21 days increased essential oil percentage in the two cuts during the both seasons. Foliar spray with micro elements Fe, Zn, Mn individually and mixture between them recorded significant increase in vegetative growth, as well as the highest essential oil content per plant in the first and second cuts of the two seasons compared to the control. In addition, the previous values of characters were increased by using (Mn) to reach their maximum values by using the mixture of (Fe+Zn+Mn) at 150 ppm in both cuts of the two seasons. The interaction between irrigation interval every 7 days with foliar spray of a mixture, followed by Mn at 150 ppm gave significant increase in vegetative growth, as well as the highest essential oil content per plant in the first and second cut of the two seasons. In addition, the irrigation intervals every 21 days with same spraying treatments gave the highest essential oil percentage compared to other ones or the control plants. The irrigation interval every 21days gave the highest main components of essential oil (camphor, 1.8-cineole and α-pinene) which recorded (50.04 %), while the interaction between irrigation interval every 21days with foliar spray (Mn) at 150 ppm gave the highest main components (65.53 %) followed the mixture of the microelements (60.85 %) of the rosemary essential oil.
