  Tomato Shading Study- Las Vegas 2018 Results Authored by Angela O Callaghan Cooperative Extension in southern Nevada has been recommending shading tomato plants in the summer to extend the season and help improve production as well as quality. The question remained “Does shading up tomatoes really help in such a harsh desert climate, and if so, how much shade? Do all tomato cultivars benefit equally?” This research aimed to obtain information that could be useful to small growers, including household growers, who must confront the in this region. We selected four commonly grown tomato cultivars: Celebrity, Early girl, Heat Wave and Red Cherry (a very small-fruited variety). The treatments were, 0%, 30% and 50% shade. We transplanted seedlings into raised beds with organically amended soils. The land where the raised beds were located where plants had not grown previously. Major problems included wind damage, sunscald, herbivory and root knot nematodes. The project had noticea...

Viability of Microorganisms in The Conditions of Permafrost Authored by Neustroev МP The generally accepted warming of the climate in the Arctic may increase the risk of the emergence and spread of infectious diseases of humans and animals due to the melting of permafrost, the intensive development of natural resources, controlled and uncontrolled paleontological excavations, expansion of vector habitats (insects, rodents), changes in the migration routes of migratory birds. It is very important to know the survival time of microorganisms in the environment for the sanitary-bacteriological assessment of environmental objects, as well as determining the possible period of contamination by their pathogenic and conditionally pathogenic microflora in case that they are released by sick animals or bacteria carriers.

Antifeedant Potential of Some Aromatic Plants Against Cowpea Weevil, Callosobruchus Maculatus Authored by Egwunyenga Ogochukwu Andy The antifeedant potential of extracts of five natural plants; Galic (Allium sativum), Manjack (Cordia millenii), African nutmeg (Mondora myristica), Negro pepper (Xylopia aethiopica) and Ginger (Zingiber officinale) against cowpea weevil, (Callosobruchus maculatus) was evaluated. The results established that extracts of Ginger caused the strongest feeding deterrency against the insect pests with percentage feeding index of 48.3%. The order of the antifeedant potency of the extracts against C. maculatus after 5-hour exposure was Z. officinale (43.9%), > X aethiopica (48.3%) > C. millenii (59.9%) > A. sativum (61.6%) > M. myristica (64.9%). The study further discussed the challenges confronting researchers and farmers in practically deploying these plant materials for general use in crop protection and makes recommendations on appropr...

Influence of Planting Dates on Cane and Sugar Yields for Some Sugarcane Varieties Authored by Mohamed Owais Ahmed Galal The present study was carried out at El-Mattana Research Station, Luxor Governorate, Agricultural Research Center, Egypt. In two plant crop seasons of 2017/2018 and 2018/2019 to study the effect of planting dates on yield for three sugarcane varieties (G.T.54-9, G.98-28 and G.84-47) grown at three planting date in mid-March, mid-April and mid-May. The date of harvesting was in mid-March for all planting dates. A split plot arranged RCBD, in four replications, was used for the experiment. The three varieties were randomly distributed to the main plot while the three planting dates were assigned to sub-plot. The results indicated that planting sugarcane in mid-March was superior in millable cane/fed, cane weight, as well as cane and sugar yields in both seasons.

Analysis of Growth Performance Data in Sheep using Linear Mixed Model Authorized by Mekonnen Tilahun The annual Ethiopian goat meat and mutton production is very low. Major causes contributing to such low meat production include slaughtering animals at immature bodyweights, poor genetic potential of the local breeds, poor feeding conditions and policy issues. Increasing the current level of productivity is essential to provide meat to the ever-increasing human population and to satisfy the huge demand of live-animal export to neighboring countries.

The Effect of Organic and Inorganic Nutrient Sources on The Growth and Seed Yield of Bambara Nut (Vigna Subterranean (L) Verdc) Variety Authorized by Getamesay Shiwenzu The research was conducted at the Teaching and Research Farm, of Federal University Wukari, Taraba State Nigeria, during the raining seasons of 2016 and 2017 to assess the effects of organic and inorganic fertilizers on the growth and seed yield of Bambara nut varieties. The treatments consisted of two varieties of Bambara nuts, (white and black varieties) and the fertilizers: organic (10, 20t ha-1 of poultry manure), and inorganic (30 and 60kgN ha-1 of Urea) with a control. These were laid out in a Randomized Complete Block Design (RCBD), with four replications.

Destroyed Windbreaks as One of The Main Causes of Agricultural Production Decrease in Georgia Authorized by Tamaz Patarkalashvili Windbreaks have very important economic, social and environmental value for sustainable development of the country. They increase crop and fruit quality and yield in sheltered areas by providing lower temperatures, increasing relative humidity and retaining soil moisture, reducing damage of soil erosion due to strong winds. The first windbreaks have been planted in Georgia in the early 1960s. Since that time they were developed in all agricultural lands in East and West parts of the country and played their positive role in increasing yields of different kind of crops (wheat, rye, corn, barley etc.), especially in East Georgia, as well as in West Georgia-tea and citrus yields (mandarins, oranges, lemons feijoas). In the Soviet period windbreaks always maintained well. To read more about this article:  Agriculture and Soil Science To kno...

On the meadow-chestnut soil of heavy mechanical composition we studied the productivity of promising varieties of winter durum wheat Grain, de-pending on the doses and timing of mineral fertilizers on the background of irrigation and semi-steam systems of soil treatment in irrigation of the flat zone of Dagestan. The purpose of the research was to obtain experimental data for the development of cost-effective and environmentally friendly resource-saving technology of cultivation of promising varieties of winter durum wheat Grain in the flat zone of Dagestan. The novelty of the research is that for the first time in the conditions of irrigation of the flat zone of Dagestan, the optimal doses of mineral fertilizers and the terms of their application for winter durum wheat, providing a significant in-crease in yield and grain quality were studied and established. On average, for 2014-2018 the maximum yield of the promising Grain variety-5.45 t/ha, on aver-age for 2014-2018, wa...

World Journal of Agriculture and Soil Science Crop performance is the results of genotypic expression modified by interaction with the environment. One of the environmental factors, that most widely limiting for the crop production is water. The deficit of water significantly limits the growth, development and yielding of crops. The paper presents a mini review of the own research results and the literature on the effect of water shortage on the rate of photosynthesis of forage grasses. A better understanding the physiological reactions of plants to water stress should improving irrigation efficiency, modifying plants for more efficient water use, and developing effective agriculture on dry area.

World Journal of Agriculture and Soil Science Potassium (K) is an essential nutrient for plant health and play critical roles in controlling protein metabolism, enzyme activity and various metabolic processes. In order to investigate the effect of different potassium rates and hybrid maize varieties on the yield and yield components of maize, an experiment was carried out at the Bajeng Experimental Station, Indonesian Cereals Research Institute, Gowa, South Sulawesi, from May to September 2017. The level of K on site of the experiment is 0.26 mg kg -1 . The potential grain yield of three hybrid maize varieties has different. Nasa-29 has potential grain yield (13.5 t ha -1 ), Bima-20 (12.8 t ha -1 ) and Bima-4 (11.7 t ha -1 ). The experiment was laid out in randomized split plot design with three replications having a plot size of 9 m x 6 m with planting density 75 x 25 cm. The main plot was provided with six different levels of potassium i.e. 0, 20, 40, 60, 80 and 100 kg...
