This article points out the ways of efficient plant nutrition with microbiological fertilizers on various mineral nutrition backgrounds. Current research is aimed at managing high lentil yields with substantiate application of microbiological fertilizers on mineral nutrition background. The article describes the elements of yield structure and grain productivity of lentil: the number of beans and seeds per plant, the weight of seeds per plant, and the weight of 1000 seeds, which is important for predicting the efficiency of a particular cultivation technique. The effect of microbiological fertilizers on the height of the lower bean attachment is assessed. It was observed that a mixture of Azotovit + Phosphatvit exerted a positive impact on this morphological trait. The obtained results allowed us to conclude that seed treatment with a mixture of Organit N + Organit P at a rate of 0.5 l/ha contributes to high lentil yields, regardless of the mineral nutrition backgrounds. Fertilizer application on the N32P32K32 background ensured a higher yield increase. The highest yield was noted with N32P32K32 when sowing lentil seeds with a mixture of Organit N + Organit P treatment at a rate of 0.5 l/ha.
Keywords: lentil, microbiological fertilizers, mineral nutrition background, productivity, yield.

This article presents data from a study on the effect of the complex fertilizer Folirus Stimul (aq. sol.) on chickpea crops in Ryazan Oblast. Proper organization of the plant nutrition system, including foliar feeding, is crucial for effective chickpea cultivation and the formation of high-quality yields. The study examined the use of three foliar applications of the complex fertilizer Folirus Stimul (aq. sol.) to chickpea plants during the vegetation period. Nutrient deficiencies significantly reduce chickpea yields and grain quality. Particular attention should be paid to the levels and availability of the micronutrients – molybdenum and boron. Applying foliar fertilizers to chickpea crops during the growing season with the studied agrochemical Folirus Stimul (aq. sol.) improved crop structure and increased the yield of the Avatar and Volzhanin varieties. There was an increase in protein content in the chickpeas of the studied varieties. On average over the study period (2024–2025), the highest chickpea yield was observed in the group that received three foliar applications of Folirus Stimul (aq. sol.) fertilizer at a rate of 4.0 L/ha. The yield increase for the Avatar chickpea variety was 13.8% compared to the control, and 11.6% for the Volzhanin variety, indicating the high effectiveness of the proposed method in chickpea cultivation practices.
Keywords: chickpeas, complex fertilizer, agrochemicals, yield, grain quality.

The rate of leaf area growth and the size of the assimilative apparatus of cultivated plants directly depend on the agricultural technologies applied. Echinacea purpurea during the early flowering cycle cannot compete with weeds. Therefore, from 2016 to 2018, for highly productive agrocenoses the effect of different agricultural technologies on photosynthetic potential of Echinacea purpurea plants in the second growing season was examined in the meadow-chernozem soil at the Penza State Agrarian University collection plot. The largest photosynthetic surface area during all growing cycles was formed by agrocenoses of winter crops, where, to control weeds, the soil was chemically treated with Lazurit, SP (0.5 kg/ha) before the flowering cycle, followed by spraying with the herbicide Miura, KE (0.6 l/ha) in the 2-4 leaf stage of annual and perennial cereal weeds. At the stem elongation stage, the leaf area was 40.29 thousand m2/ha, within the bud stage it increased by 7.79 thousand m2/ha, and during the flowering cycle it reached a maximum of 50.28 thousand m2/ha. When weeding manually, the data was slightly lower. During the stem elongation stage, the leaf area was only 1.50 thousand m2/ha less, within the bud stage – by 1.32, and during the flowering cycle – by 0.34 thousand m2/ha. The photosynthetic potential in the first growing season was maximum – 1,516 thousand m2 · day/ha. A particularly significant advantage was achieved by applying herbicides twice, so the photosynthetic potential in the second growing season was 1,679.5 thousand m2 · day/ha. The maximum net productivity of photosynthetic potential of 2.63g/m2 ∙ day was observed during the bud-flowering cycles, when leaf area rapidly increased to its maximum and without any sharp decline for a long time. The highest value of 3.02 g/m2 ∙ day wad gained with the Miura herbicide treatment in the 2-4-leaf stage of early spring sowing.
Keywords. Echinacea purpurea (Echinacea purpurea (L.) Moench), leaf surface area, photosynthetic potential, net photosynthetic productivity, sowing, weed control, herbicide.

Maximizing efficiency in poultry farming requires the considerable improvement of organizational and technological processes at poultry farms. Poultry farms and feed mills have to control diet composition to in-crease the poultry genetic potential with the high-quality feedstuff and the cost-effective approach. Quality requirements in the modern poultry industry depend on the level and quality of protein feeding. Protein is the main micronutrient for high-quality meat. Currently, the alternative plant protein sources are becoming highly important, such as white lupine seeds, which contain 33-39% protein. Lupine is a relatively new crop in the Penza region. Therefore, it is necessary to study the possibilities of lupine cultivation in the Penza region, as well as technological methods of white lupine seeds treatment to provide nutrition to poultry birds and im-prove their digestion.
The research, carried out by the Penza State Agrarian University scientists, confirmed the hypothesis that partially replacing soybean meal with barohydrothermally treated lupine seeds had a beneficial effect on the metabolic processes of poultry, facilitating the genetic potential of broiler chickens. Since feed accounts for the majority of production expenses, it was noted that in the group where 50% of soybean meal protein was replaced with treated lupine protein, expenses decreased by 3.75% compared to the control group. This cost reduction directly impacts production costs. The cost per kg of the carcass in the second experimental group was 17.8% lower than in the control group, and 3.2% lower than in the first experimental group. Includ-ing lupine in animal diets, along with processed soy or sunflower products, gives new opportunities for feedstuff improvement. It could allow feed producers to use more affordable feedstuff resources and reduce expenses significantly.
Keywords: lupine, broiler chickens, feeding, efficiency, cost price, live weight.
