Cultivating spinach during autumn, as a sealing crop, has important economic and agro-ecological significance both through the yields achieved and by the more complete and rational utilization of the residual nutrients in the soil after harvesting the previous main crop. A field experiment with spinach variety Matador is conducted on the alluvial-meadow soil. The soil reaction (pH) is slightly acidic, humus content is low (1.33 %). The availability of mobile forms of N, P and K variants of an experiment in post-harvest predecessor are low mineral nitrogen and high P2O5 and K2O. The study aimed to assess the post-effect of organic, mineral and mixed manure and mineral nutrition in the predecessor previous crop early potato with many treatments. Control variant without nutrition (T1), with organic (manure) (T2), with mineral (T3), and with mixed 50% manure-50% mineral nutrition (T4). The effect of treatments on growth, yield, quality of production and quality parameters in autumn growing Spinach (Spinacia oleracea Linn) has studied. The experiment is a completely randomized design. The results indicate that the highest yield of spinach is obtained from the plants with post effect of the mineral nutrition. Plants are grown after mineral nutrition has higher nitrogen, chlorophyll and nitrates contents. The dry matter content and total sugars are highest in the production of spinach after the previous crop fertilized with manure. |
