Impact of precipitation and temperature on winter wheat yield at different sowing densities

Abstract

Agro meteorological conditions are of great importance for the successful production of wheat. This paper analyzes the NS five varieties of winter wheat in the period 2010-2012. The experiment was conducted with different planting densities at the site Rimski Šančevi. Unlike the temperature, the amount and distribution of precipitation had a greater impact on the realization of the yield. Higher average grain yield was achieved at a higher sowing density, where, among analyzed varieties no big difference was observed between the yield at a lower or higher sowing norms. To make the right conclusions it is necessary to include a greater number of sites and different growing seasons.

Agrometeorološki uslovi od velikog su značaja za uspešnu proizvodnju pšenice. U radu je analizirano pet NS sorti ozime pšenice u periodu 2010-2012. Ogled je postavljen sa različitim gustinama setve na lokalitetu Rimski Šančevi. Za razliku od temperature, količina i raspored padavina imali su veći uticaj na realizaciju prinosa. Veći prosečni prinos zrna ostvaren je pri većoj gustini setve, pri čemu, između analiziranih sorti nije uočena velika razlika u prinosu pri manjoj, odnosno većoj setvenoj normi. Za donošenje pravilnih zaključaka neophodno je obuhvatiti veći broj lokaliteta i različitih vegetacionih sezona.
