The Effect of the Timing of Manure Application in Combination with Mineral Fertilizers and Planting Density on the Weediness of Potato Plantings

Potatoes are one of the most responsive crops for grooming techniques since in period from seedlings before closing rows easily suppressed by weeds that take away nutrients, water, light it. The factor causes high harm to potatoes is weed. By absorbing a large number nutrients and moisture soil, inhibit growth development plants, reducing their potential productivity. purpose study was establish effect timing introduction bedding manure conjunction with mineral fertilizers planting density on weediness potato plantings. Studies were provided identify impact together weed potatoes. Experiments laid systematic method tiered arrangement variants experiment 3-fold repetition. We used cattle straw autumn-winter harvesting. following types used: ammonium nitrate, double superphosphate, potassium chloride. Determination amount biomass plantings carried out flowering phase application accompanied an increase weight weeds. Annual predominated plantings: Amaranthus retroflexus L., 1753 blitoides S. Watson, 1877, Chenopodium album L. 1753, Setaria P. Beauv, 1812 viridis (L.) 1812, Echinochloa crus-galli BEAUV., others, perennials included Cirsium arvense SCOP. 1772 Sonchus arvensis (Elytrigia repens DESV. ex NEVSKI, 1933 others. Planting also has definite When applied autumn under plow, increased comparison other options, where only applied. over frozen plow winter snow leads slight decrease (2.3-2.5 pcs/m2) greatest observed during spring plowing fall plow. Nevertheless, studies aimed at clarifying composition structure weediness, great practical importance local agricultural producers. These data should contribute effective control system yields region
