Abstract
The article deals with the study of the influence of various resource-saving systems for the treatment of light-gray forest soil and the use of fertilizers and the biopreparation Stimix®Niva on the contamination of pea varieties of the "Beautiful” variety and its yield in the Nizhny Novgorod region. The highest contamination of pea crops was revealed in the variants of field experience, where it was cultivated according to the No-till technology as at the beginning (23.3-36.5 pcs/m2 total, including 18.0-31.0 pcs./m2 perennial contamination), and at the end (23.0-43.8 pcs./m2 total, including 18.8- 39.8 pcs./m2 perennial contamination) of vegetation. The use of Stimix®Niva when growing peas in accordance with the traditional tillage system by the end of its growing season on a non-fertilized background reduces the contamination of crops to 12.5 pcs/m2. Between the total weed infestation of pea crops in the phase of full ripeness of grain and its yield, a strong inverse correlation was found, the correlation coefficient is -0.86. The highest yields of pea varieties "Beautiful” were obtained in the variants where in the system of the main tillage, autumn plowing was used with reservoir turns to a depth of 20-22 cm with the use of ammonium nitrate as a destructor at a dose of 10 kg per 1 ton of straw, as on the background mineral fertilizers (2.76 t/ha) and non-fertilized background (2.70 t/ha). With a decrease in the depth of processing of light-gray forest soil, a decrease in the yield of pea grain per hectare was revealed. When using the No-till technology, the yield of peas is the lowest - 0.74-2.24 t/ha. The use of the background of N60P60K60 fertilizers according to the No-till technology together with the Stimix®Niva biological preparation, as a straw destructor, allows to obtain the pea yield in the Nizhny Novgorod region conditions of 2.24 t/ha.
