KnanySoils, Water and Environmental Research Institute - Agriculture Research Center, Giza, EgyptJournal Article20201102A pot experiment was conducted during 2018 and 2019 seasons in Sakha Horticulture Research Station, Kafr El-Sheikh Governorate, Egypt to study the effect of foliar application of potassium sulphate 50%, potassium nitrate 43% (1, 2 and 3 g/l water) and potassium silicate 38% (1, 2 and 3 ml/l water) on growth and flowering of snapdragon <em>(Antirrhinum majus</em> L.) plants. The results indicated that foliar spraying with the different potassium treatments significantly affected all the studied parameters in terms of plant height, number of shoots per plant, fresh and dry weight of plant, roots and flower, number of flowers per plant, spike length, total chlorophyll content andnutritional status (N, P, K and Si) as compared with control. Foliar spraying with potassium sulphate at 3 g/l water gave the significantly highest values of plant height, number of shoots per plant, fresh and dry weight of plant, roots and flower, number of flowers per plant, spike length and total chlorophyll compared to other treatments. Data showed also that, growth parameters, flowering characteristics and nutritional status were significantly increased with increasing the levels of potassium from 1 to 3 g/l water or ml/l water under the same source of potassium. So, it can be concluded that potassium foliar spray can be used as a partial substitution of the recommended soil amended potassium for increasing nutrients uptake and thus stimulating growth and flowering characteristics of snapdragon <em>(Antirrhinum majus</em> L.) plants and potassium sulphate at 3 g/l water can be used in this respect.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111120201101Phylogenetic Diversity of Trifolium L.

Therefore, these two crosses would be useful in breeding programs for improving the studied characters.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111120201101Farmer's Behavior and Attitude in Using Chemical Fertilizers and Pesticide in Rural Areas1077108113091510.21608/jpp.2020.130915ENSumaia M.RaheemAgribusiness and Rural Development Department, College of Agricultural Engineering Sciences, University of Sulaimani, Sulaimani City, Kurdistan Region, Iraq.Hawall I.RasulAgribusiness and Rural Development Department, College of Agricultural Engineering Sciences, University of Sulaimani, Sulaimani City, Kurdistan Region, Iraq.Rezhen HarunAgribusiness and Rural Development Department, College of Agricultural Engineering Sciences, University of Sulaimani, Sulaimani City, Kurdistan Region, Iraq.Journal Article20201114Human activates especially farmers can have impacts on the environment via using chemical substances, these effects can be directly on human or indirectly through food, wildlife, climate, crops, or livestock. Chemical substance which are created to introduce into delicately balanced ecosystems, they could have led to damage in motion that reverberates via the food for years. Nevertheless, it wreaks havoc, biodiversity and the natural system that human survival depends on. The aim of this study is to evaluate farmer’s behavior in using pesticides and fertilizers to prevent the environment pollution and the harm to the human beings. Primary data was used to achieve the objective which using a semi-structure questionnaire, that administered in a random sampling technique, face to face administration. The total number of farmers in the sample was 200 farmers in 31 villages. The analysis is conducted with SPSS and Excel Spreadsheets. The results illustrated that great number of farmers in rural area of Sulaimani uses chemical pesticides and fertilizers in huge amounts, they still with the adage, “if little is good, a lot more will be better”. In addition, the great number of farmers don’t follow the product’s labels, or believe that these chemical substances impact on the environment, or adopt new techniques in applying chemical substances. So, farmers require knowledge and informations to understand the negative influences of these chemical substances on the biotic and abiotic components of the environment to use organic fertilizers and pesticides instead of toxic chemicals with the recommended standard levels.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111120201101Response of Snap Bean Plants to some Treatments under Temperature Stress Conditions1083109613092110.21608/jpp.2020.130921ENHala A.El-SayedHort.

Sakha108 was developed from backcrossing between Sakha101 and HR5824-B-3-2-3 to retrieve blast resistance that was broken in wide spread variety Sakha101. The cross between Sakha101 and HR5824-B-3-2-3 was initiated in 2003, F<sub>1</sub> then was backcrossed with Sakha101 as to produce F<sub>1</sub>BC<sub>1</sub>. This backcross was advanced up to 2008 to enrich the genetic background of the recurrent parent Sakha101 along with blast resistance and reach homozygosity up to F<sub>1</sub>BC<sub>6</sub>. Five selected promising sister lines were evaluated in preliminary yield trial (GZ8564-SP70-20-6-1-1, GZ8564-SP70-20-6-1-2, GZ8564-SP70-2-6-1-3, GZ8564-SP70-20-6-1-4 and GZ8564-SP70-20-6-1-5). The promising line GZ8564-SP70-20-6-1-1 surpassed all selected lines and was evaluated from 2010 to 2015 in multi-location yield trials, regional, final and verification yield trials. The results indicated that GZ8564-SP70-2-6-1-1 exceeded yield potential of recurrent parent Sakha101, yet with shorter growth duration and blast resistance. The selected line grain yield recorded 10.75 and 11.00 t/haduring 2015 and 2016 seasons with total duration 137 day, while Sakha101 recorded 10.32 and 10.50 t/ha, <sup> </sup>respectively with a total growth duration of 145 day. GZ8564-SP70-2-6-1-1 showed high level of blast resistance in the field and artificial inoculation under greenhouse conditions compared with Sakha101 that showed susceptible reaction to rice blast under both field and greenhouse conditions. The application of 165 kg N/ha<sup>-1 </sup>and wider space (25x20 cm) significantly increased growth, yield attributes and grain yield of the new cultivar Sakha108. The new cultivar exhibited multiple resistance to other important biotic stresses.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111120201101Effect of Organic, Chemical Fertilizations and Plant Stimulants on Eggplant (Solanum melongea L.)

Center, Giza.Journal Article20201120Two experiments were carried out at a private Farm in Rowad Village belong to Sahl El-Husseiniya, Sharkia Governorate through 2019 and 2020 seasons to determine the impact of organic,chemical fertilizations and spraying with some plant stimulants (yeast extract, potassium silicate and chicken manure tea) on growth traits, yield and its components and chemical ingredients of eggplant(Black Beauty cultivar) grownup under saline soil. The experiments were conducted using split-plots design with three replications. Organic and chemical fertilization treatments were arranged in the main-plots. The sub-plots were assigned to some plant stimulants (yeast extract, potassium silicate and chicken manure tea) treatments.The obtained results showed that growth, yield and its components and chemical ingredients of both eggplant leaves and fruits were significantly affected by the different levels of organic and chemical fertilization in both time of years. The supreme values of these traits were obtained from using 100%of (NP and K)chemical + 0% of (FYM) farmyard manure fertilizers,50%of NP and K+ 50% of FYM and75%of NP and K+ 25% of FYM fertilizers.Spraying eggplant plants with potassium silicate, chicken manure tea and yeast extract significantly improved growth, yield and its components and chemical in gredients in leaves and fruits through both years. It could be recommended that spraying eggplant plants with yeast extract with using50%of NP and K+ 50% of FYM to enhance growth, yield and its components and chemical ingredients under the ecological situation of this research.
