Abstract :

The experiments were established on the experimental fields at the Training and Research Farm Peterlauki of the Latvia University of Agriculture. The soil at this site is an Endogleyic Calcisol (GLu) with pH KCl 6.8 and low humus content (20 g kgE-1). Half of the six plots (three variants) were conventionally tilled (CT), but the other half of the plots were subjected to a reduced tillage (RT) ...

Abstract :

Soil tillage is one of the most power-consuming and expensive processes in agricultural production. The minimum tillage practices have significant ecological as well as agronomic impact by reducing the soil disturbance and enhancing the soil system stability. The paper presents the results of stationary field experiments carried out in the Training and Research Farm Peterlauki of Latvia Univer ...

Abstract :

Winter wheat is the most important cereal in Latvia. Sowing time is one of the critical elements of growing management, and due to this it has been investigated periodically since 1920ies. The aim of our paper was to analyze the impact of sowing time on winter wheat yield in its main growing areas in Latvia – Zemgale and Kurzeme. Published papers and scientific reports were used, as well as th ...

Abstract :

Long-term field experimental plots were established at the Training and Research Farm Peterlauki of the Latvia University of Agriculture in the autumn of 2008. Experiments were carried out under the conditions very similar to the actual crop production conditions; the total plot area was 6 ha, the area for each treatment – 0.25 ha. Two-factor trials were established: A – soil tillage: 1) soil: ...

Abstract :

Winter wheat (Triticum aestivum L.) is a crop of worldwide importance as well as in Latvia. Grain quality adversely affects price and consumer acceptance of finished products. Field experiments with winter wheat cultivars ‘Bussard’ and ‘Zentos’ were conducted at the Latvia University of Agriculture, Training and Research Farm Peterlauki in 2009/2010 and 2010/2011. The aim of this investigation ...
