Opis:
The aim of the study was to determine the response of new cultivars of spring barley in terms of the grain yield, yield components and protein content in grains, to an increase in the sowing rate. Microplot experiments were carried out in the IUNG-PIB experimental plot in Puławy, where the influence of the following sowing densities on the yielding of selected cultivars was studied: 250, 350 and 450 grains m-2. In the years 2011–2012, the following cultivars were investigated: Basic, Goodluck, Iron, KWS Olof, Natasia, and in the years 2012–2013 cultivars: Despina, Ella, Fariba, Gawrosz (hulless variety), Kucyk and Raskud. The experiments were carried out on a soil of a good wheat complex (heavy loamy sand deposited on light loam). An increase in grain yield (averaged across cultivars) was obtained as the sowing density was increased up to 450 grains m-2. At a high sowing rate (450 grains m-2), a significant increase in the grain yield of the following cultivars occurred: Basic, Iron, Despina and Gawrosz, and an increase in the yielding of other cultivars at this sowing rate, compared to the sowing rate of 350 grains m-2, constituted a trend. The largest increases in the yield at a high sowing rate, in comparison to the low rate in the first series of experiments (2011–2012), were demonstrated by the following varieties: Iron (29%), Basic (25%) and Goodluck (21%), and smaller increases were noted for the cultivars: KWS Olof (13%) and Natasia (10%). In the second series (2012–2013), higher yields at a high sowing rate, as opposed to a low sowing rate, were demonstrated by the following cultivars: Gawrosz, Raskud and Despina (31–34%), and lower yields by: Ella, Fariba and Kucyk cultivars (19–21%). The increase in grain yield at a high sowing rate was the result of a bigger number of ears per unit of area in all cultivars (especially in the Basic and Raskud cultivars). The difference in the weight of 1000 grains and the number of grains per ear of the investigated varieties as a consequence of the sowing rate was negligible. In the years 2012–2013, there occurred an increase in the protein content of grains at a high sowing rate. Among all the cultivars (on average considering the sowing rate), the highest grain yields were produced by Iron and Ella, the highest density of the number of ears per unit of area was demonstrated by Natasia, Kucyk and Ella. The cultivars Iron, Gawrosz and Raskud were found to have a significantly higher number of grains per ear than the remaining cultivars.

Opis:
The influence of various irrigation methods on the soybean water consumption rates and yield has been studied. It was established that the yield of the Lastochka soybean variety using the drip irrigation was 52.6 c/ha under the conditions of the Ili Alatau and 49.6 c/ha in the Kyrgyz Alatau, which is 8.0–8.14 c/ha more than when using the furrow irrigation. In both zones, the soybean consumption rates depended on the soil-hydrogeological state of the land.

Opis:
In the years of 2013–2014, pot experiments were conducted to determine the influence of sowing depth and seed size on the dynamics of spring wheat emergence and yields. The study was carried out in Mitscherlich pots using the random block method, in four replications. The experiment included spring wheat cultivar Tybalt. The first factor of the experiment was the sowing depth of seeds (1, 3, 5, 7 cm), while the second factor was the seed yield. Four levels of the second factor were taken into account: a1 – certified material (purchased), a2 – small-sized seeds (1.8 – 2.2 mm), a3 – medium seeds (2.2 – 2.5 mm), a4 – large seeds (> 2.5 mm). Adequate size of seeds for the study was ensured by sorting out of the certified material on Vogel screens. The research showed the joint impact of seed size and sowing depth on grain yield formation, number of plants and ears per pot and production tillering. The application of the sowing depth of 7 cm resulted in a significant decrease in grain yield from the pot of all seed fractions, especially the smallest fraction of seeds (1.8 – 2.2 mm). The variant of sowing large seeds (> 2.5 mm) at the depth of 3 cm turned out to be the most beneficial for grain yield.
