W roku 1994 prowadzono badania nad wzrostem i rozwojem czterech gatunków roślin (ślazowca pensylwańskiego, topinamburu, wikliny i ligustra) w warukach laguny osadowej oczyszczalni ścieków w Hajdowie i glebie mineralnej GD Felin koto Lublina. Sztobry ligustra i wikliny zaschły po kilku miesiącach od wysadzenia. Rozwój topinamburu byt ograniczony do jednego okresu wegetacyjnego. Jedynie u ślazowca obserwowano...
The paper presents methods and results of studies on the parameters of water transport in wheat kernels in three wheat varieties: Jara, Kadett, and Henika coming from two different nitrogen fertilization levels (50 and 150 kg N/ha).
In the study the authors determined the weed-killing properties of the keratin-bark-urea granulate applied in doses of 200 to 1500 kg/ha in pre-sowing and top-dressing applications, in fields of winter wheat, spring wheat, spring barley, and spring rape. It was found that the weediness of the crops studied depended solely on the dosage of the granulate applied, but was independent of the time of application...
In the paper the authors present the results of studies on the quantitative-qualitative relations of the weediness of oats and winter wheat, grown after winter wheat and spring rape respectively, fertilized the preceding year, in two terms, with 200 to 1500 kg/ha doses of the keratin-bark-urea granulate. It was demonstrated that the granulate in question caused only certain tendencies of changes in...
Three varieties of spring and 3 winter varieties of wheat were examined on soil containing high mineral fertilizer doses. For spring varieties: Jara, Alfa and Ród M the following fertilizer doses were used: 200, 400 and 600 kg/ha and for winter varieties: Panda, Grana and Liwilla - 250, 500 and 750 kg/ha. Basic physical properties, such as 1000 grain weight, volume weight, glassy and superior grain...
In a three-year field experiment carried out on a brown soil developed from light loam, the author studied the effect of the keratin-bark-urea granulate on the seed yield of spring rape variety Mazowiecki. The experiment comprised the following variants - varied dosage of the granulate (100, 150, 200, 500, 1000, and 1500 kg/ha); reference variant (no granulate); and a variant with a herbicide (Kerb...
In the years 1981-1984, at the Agricultural Experimental Station at Felin near Lublin, field experiments were carried out on the crop yields of three varieties of winter wheat (Grana - Liwilla - Panda) under the effect of three sowing rates (3 - 4.5 - 6 million grains per hectare) and three levels of mineral fertilization (250 - 500 - 750 kgNPK/ha). Only several days differences in the duration of...
In a three-year field experiment carried out on a brown soil developed from light loam the author studied the residual effect of keratin-bark-urea granulate on the crop yield of winter wheat and oats. Successive increase in the yield of wheat grain was observed with increasing doses of the granulate; in the case of oats a positive effect was observed at granulate doses of 500-1000 kg/ha. The highest...
В 3-летних полевых опытах, проведенных на бурой почве, образованной из легкой глины, исследовано влияние кератино-коро-карбамидного гранулята на развитие и урожайность мровой и озимой пшеницы и ярового ячменя. Полученные результаты доказывают небольшое и не одинаковое для отдельных видов влияние примененного гранулята. Положительное влияние гранулята на урожайность отмечено у озимой пшеницы (сорт...
