Effect of vegetation area size on alfalfa seed yield

Abstract

This paper surveys sowing norms (row spacing and seed rate) in both the world and our country, optimal seed rates in alfalfa seed production. A short overview of row spacing and seed rates applied in the world and Yugoslavia is given. In our country alfalfa was grown for seed production on large acreages. However, according to some research high seed yields may also be achieved by cultivating alfalfa on smaller vegetation area. Seed yields achieved from crops intended for forage production may exceed seed yields from crops intended for seed production only.

U radu je dat pregled setvenih normativa (načina setve i količine semena) u svetu i u našoj zemlji, najoptimalnije količine semena pri setvi u proizvodnji lucerkinog semena. Takođe je dat kratak osvrt na način i gustinu setve koji su se primenjuju u svetu i način i gustina setve koja se primenjuje u našoj zemlji. U ranijem periodu u našoj zemlji su uglavnom biljke lucerke za proizvodnju semena gajene na većem vegetacionom prostoru međutim, neka istraživanja ukazuju da se visoki prinosi lucerkinog semena mogu postići i pri gajenju biljaka na manjem vegetacionom prostoru, tj. usevi namenjeni za proizvodnju krme u prinosu semena mogu nadmašiti i namenjene za semenske useve.
