RESEARCH CONCERNING THE INFLUENCE OF SOWING PERIOD AND ROW DISTANCE ON THE NUMBER OF SPIKES AND THE NUMBER OF PLANTS ON A SQUARE METER OF AUTUMN WHEAT IN WESTERN ROMANIA PUBLISHEDMarcela Dragoş, Paul Pîrşan
The results of this study are part of a PhD program, having as theme: " Research on sowing technology ofwinter wheat in Western Romania ", funded by the European Social Fund, the Pilot Program PhD Research Scholars Support Contract from the POS DRU / 6 / 1.5 / S / 21 USAMVB Timisoara, under the leadership of the distinguished university professor Paul Pîrsan. The paper presents the results obtained in the last two years of experience, about the influence of sowing period and row distance on the number of spikes and the number of plants on a square meter, specifically at the Teaching Resort of University of Agricultural Science and Veterinary Medicine of Banat Timisoara, located in the Plain Banato-Crisan, Plain subunit Berecsău Bega-Timis interfluve. Researches were conducted on a chernozem soil, low gleyed, formed on decarbonated loesoide deposits. The goal of the research is to establish seeding technology under current climate conditions, based on the frequent situations in which, for various reasons we can’t saw in the optimal sowing period. Wheat is a grass, originally from the Fertile Crescent region of the Near East, but now cultivated worldwide. The material investigated is the variety Alex (Lovrin 50), variety created by S.C.D.A Lovrin and approved in 1994. Variety Alex is the representative variety for the western part of the country and has the largest expansion in the mentioned area. Among the biometric measurements performed through direct measurements in the field, the number of plants per square meter and number of spikes have an quantitative influence on the production. Number of plants per square meter ranged between 168, obtained in the first year, and 280, obtained also in the first year. The number of spikes on a square meter ranged between 420, obtained in the first year, and 809, obtained in the second year.
