Effects of organic-inorganic slow release fertilizers on yield and nitrogen recovery in tomato

Pot experiment was conducted to investigate the effects of organic-inorganic slow release fertilizers on yield and nitrogen recovery in tomato.The results showed that the application of organic-inorganic slow release fertilizer B increased nitrogen recovery rate,and increased the distribution proportion of nitrogen in fruits and leaf; New type fertilizer B application improved the yield componet at latter stage,and increased yield by 17.13%.Application of organic-inorganic slow release fertilizer A2 was also increased the nitrogen recovery rate, raised the proportion of nitrogen in roots and leaf and increased yield by 16.33%.Organic-inorganic slow release fertilizer A2 was litter effect on nitrogen recovery rate and yield of tomato.
