Effect of nitrocalcuumphosphate fertilizer on the potato yield and quality

This report lists results of testing a new fertilizer, nitrocalciumphosphate (NCF) produced by open join stock company "Samarkandkimye", on the grow, develop and yield of potato under conditions of Golodnaya Step' area of Uzbekistan. From the experimental results is defined year norm of the fertilizer on typical gray desert soil of low salinity: 20 ton of semi-rotten manure + N-220 P-165 K-125 kg per hectare. For soils of moderate salinity is recommended to apply 40 ton of semi-rotten manure + N-220 P-165 K-125 kg per hectare. It is confirmed that application of organic and mineral fertilizers for potato at optimal norm improves feeding regime of soil, increases yield and quality of tubers and improves significantly meliorative situation in solanized soil.
