The purpose of the study is to identify the effect of grassland crop rotation crops on the physical, agrobiological parameters of soils and on crop productivity in the forest-steppe zone of the Republic of North Ossetia-Alania. Tasks of the experiment: to study the structural and aggregate composition of the soil; to determine the volume mass of the soil under crop rotation crops; to identify the general biological activity of the soil; to identify the effect of crop rotation crops on productivity. The object of the study is the crops of the grassland crop rotation. The research was carried out in the field stationary crop rotation of the NCMPARI VSC RAS in the conditions of the forest-steppe zone of the RNO-A. The soil of the experimental site is represented by leached chernozems on pebbles, where humus ranges from 3.4 to 4.7%. The experiments were carried out in triplicate. The area of the experimental plots is 100 m2 and registration plot is 96m2. It was found that at the beginning of the growing season, the lumpy fraction under crop rotation crops varied from 13.50% to 50.10%, and soil lumps from 0.25 to 10 mm (macrostructure) – from 49.40% to 82.60%, fraction <0.25 mm – from 1.80 to 8.0%. The index of the structural coefficient ranged from 2.22% (corn) to 2.49% (oats + clover). Studies have proven that leached chernozems contain from 45.0 to 66.5% of aggregates that resist the eroding effect of water, so these soils have a good structure. Over the years of research on oats + clover crops (on average 0–30 cm of soil layer), the soil density was 0.95 g/cm3 at the beginning of the growing season, 1.19 g /cm3 during the period of intensive growth, 1.22 g/cm3 at the end of the growing season. This tendency is evident in all crop rotation crops. In our studies, the best indicators for the collection of forage units were the grass links of the crop rotation and amounted to 15.05 t/ha. In the rowed link of the crop rotation they amounted to 13.12 t/ha. In general, the energy value of the grassland link of the crop rotation turned out to be 216.45 MJ more than the tilled one, and amounted to 255.0 MJ/ha.

Modern intensification of agriculture has significantly speeded up the processes of land destruction and loss of its fertility. This has led to the deterioration in the agroecological situation, boost in the potential fertility of land, and a significant decrease in yields and quality of agricultural products. The purpose of our research was the rational use of land, while compacting the link of the grain crop rotation. The studies were carried out in the foothill zone of the Republic of North Ossetia – Alania, on leached chernozems, in the subzone of sufficient moisture. In the experiments, oats were sown in pure form, mixed with peas, as well as a variant of a pea-oat-sunflower mixture, with harvesting terms for green fodder, grain haylage and grain. Today pea-oat-sunflower mixture, unlike corn for silage, is a resource-saving, low-cost and multicomponent mixture. After harvesting these crops, the crop rotation is compacted by buckwheat crops for grain. With such a sparing use of land resources, the high self-cleaning ability of these mixtures and buckwheat reduces the cost and increases the productivity of arable land. An increase in soil fertility is achieved by introducing green manure crops (winter and spring rapeseed, oilseed radish, white mustard, winter rye, etc.), which, when plowing, improve the soil structure (structural coefficient up to 3), boost the humus content in the soil by 0.02 – 0.05%, neutralize the acidity of the soil environment (up to pH = 5.5 – 6,7), clean the soil from excess nitrates, heavy metals, pesticide residues, etc., and enhance the yield by 15-20%.

“…Nitrogen fertilization increases maize grain yield (43-68%) and biomass (25-42%). Organic and inorganic nitrogen sources have a positive interaction for increasing crop yield and improving soil fertility (Mahmood et al, 2017;Mamiev et al, 2019;Partey et al, 2018;Sofyan et al, 2019;Tonitto & Ricker-Gilbert, 2016). Synergistic effects of nitrogen and organic manure accumulate more total nitrogen in the soil.…”

“…There is an urgent need to increase the judicious use of available land through the integrated application, particularly nitrogenous fertilizer, to meet the everincreasing food requirements human population and maintain soil fertility for optimum crop production (Mahmood et al, 2017;Mamiev et al, 2019;Partey et al, 2018;Sofyan et al, 2019;Tonitto & Ricker-Gilbert, 2016). Organic matter like manure promotes seed germination and the crop plants' root growth by improving the water holding capacity and the soil's aeration.…”

Maize is one of the staple foods that supply the world's food demand. The research aims to determine financial analysis of nitrogen fertilizers and planting systems and its implications on maize agribusiness. The research was conducted in experimental design with a split-plot arrangement comprising four replications. Maize plant density as a system treatment was allocated to main plots (65,000; 75,000; and 85,000 plant per ha). Integrated nitrogen was assigned to sub-plots: control; 0% yard manure (YM) + 100% urea; 100% YM + 0% urea; 50% YM + 50% urea; 75% YM + 25% urea; and 25% YM + 75% urea. Data were recorded on plant harvest, harvest index, and R/C ratio. The result showed that integrated N of 50% Farm Yard Manure + 50% urea in 85,000 plant per ha resulted in a higher harvest index of 31.5% and the highest R/C ratio of 6.2 and enhanced yield of 4,219 kg per ha. This yield almost meets the government's expectations. Total cost was 36,961 PKR, total income was 227,941 PKR, and economic net return reached 190,980 PKR. The government can support the maize crops farmers to activate decomposition household's waste to be organic fertilizer in their house and provide the place for decomposition activity in the crops field to fulfill production government target, food security, and environmental health.JEL Classification: Q01; Q12; Q18
