It was found that the use of mineral fertilizers for the main processing improved the indicators of the effective fertility of ordinary chernozem. Their combined use with foliar feeding of spring barley plants with growth stimulants reduced the content of nitrate nitrogen at low and medium doses of NPK. An increase in the concentration of nitrogen in the vegetative mass of plants with the use of fertilizers was noted.

This study was aimed to identify the effect of temperature and humidity on nectar volume, the nectar secretion dynamics, honey production potentiality, and the number of bee colonies required to be placed in a hectare of coffee plantation for optimum honey production. The study was conducted in Gera District western Ethiopia. One day before nectar measuring, 5 inflorescences were covered with fine mesh bags on a different part of the tree. From covered inflorescences, twenty flowers per tree were randomly selected and nectar volume was measured using micropipettes. Accordingly, nectar volume and concentration, temperature, and air humidity were measured with an interval of one hour. The average nectar volume (µl) per flower in 24 hours, sugar amount per tree (g), expected honey yield per tree (kg) and honey (kg) production potential per hectare for C. arabica were 3.3 + 0.2, 0.040 + 3, 0.050 + 4 and 125 kg (25-275 kg), respectively. The actual harvestable amount of honey is half of the potential (62.5 kg/ha). If a kilogram of C. arabica honey would be valued at 6.25 USD, the total financial to be expected is $ 390.63 per hectare. The mean nectar volume and concentration have significant differences (p<0.05) at different hours of the day. Nectar volume was positively correlated with humidity while concentration positively correlated with temperature. One hectare of productive trees of C. arabica holds 4 or 3 or 2 honeybee colonies for traditional or transitional or frame hives respectively. From this study, it is concluded that Coffee is not economically valuable only for its seeds, but also for honey production. Therefore, the integration of coffee plantations with beekeeping is recommended.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46715320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The history of breeding development is presented. The main research methods (free pollination and artificial hybridization, interspecific and intervarietal) are described. The main task of selection is formulated: the study of introduced domestic and foreign cultivars, the selection of the best of them to create their own varieties with high winter hardiness, not susceptible to diseases and pests, with different flowering periods that fit into the growing season of the Republic of Bashkortostan. The characteristics of new varieties of Hippeastrum (Akademiya, Akbuzat, Bashkiriya, Velikiy Motsart, Galina Shipayeva, etc.), Iris (Akmulla, Amina, Zigalga, Inzer, Irendyk, etc.), Paeonia (Avrora, Arkaim, Iremel, Lyudmila Mironova, etc.) and Chrysanthemum (Direktor Z.Kh.

One of the most important intensification factors is the use of a fertilizer system. The fertilizer system includes the selection of the best combinations of various types, forms and doses of fertilizers, applied at the optimal time and providing the maximum increase in yield from fertilizers directly in the year of use. At the same time, it should be noted that the most positive effect of fertilizers is manifested in the case when their use is put on a scientific basis, depending on the biological characteristics of the culture, variety and soil and climatic conditions. The correct use of fertilizers should be economically profitable, ensure the production of more high-quality products with relatively less additional costs of production means and labor. Field experiments are often a long-term and costly undertaking. In order to eliminate these shortcomings, they resort to using economic and mathematical methods in the practice of an agrochemical experiment to optimize the fertilizer system.","PeriodicalId":43365,"journal":{"name":"Journal of Agriculture and Environment for International Development","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2021-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72531975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
