The purpose of research is to identify the influence of the fertilizers aftereffect and ameliorator for yield formation and quality of winter wheat grain Bezostaya 1after predecessor (potatoes) in the unirrigated soils of the Askeran region of NKR in 2011-2014. It should be noted that the winter wheat in the region is an advanced crop, but due to lack of irrigation water and the lack of rainfall is often collected by low yields. Research has established that the aftereffect of fertilizers and meliorants noticeable effect for growth, grain quality and yield formation, the amount of which depends from the application of the system of fertilizer. It is proved that more weak effect preserved when under a precursor have been made only mineral fertilizers (N90P90K90), where as potassium fertilizer was used potash (N90P90K90 option), and when on the same background was used gypsum or bentonite. If in the system N90P90K90 fertilizer (KCl) instead of KCl was used treated dacitic tuff (OTD) or on the same MM backdrop bio-fertilizer, as well as an option manure 30 t/ha + N90P90K90 (KCl), the consequence was significant. In these embodiments, the yield increase compared to control 1 (no fertilizer) was 30.2-57.2%, as compared to the control 2 (N90P90K90 option (KCl) – 10.8-30.6%. In these embodiments, the content of NPK was high in the grain: 1.90-2.15% N; 0.93-0.97% P2O5 and 0.77-0.85% K2O, whereas in the control 1 1.78% nitrogen, phosphorus – 0.69%, 0.53% potassium, and in control 2, accordingly – 1.80%, 0.81%, 0.65%.
