Effects of fertilizer and planting density on yield and agronomic traits of non-tilling maize planted on rice field

Taking maize variety Guixing as material，experiments were carried out by two factors split plot design，setting slow controlled-release fertilizer rate as main treatment with 4 levels，and planting density as auxiliary treatment with 4 levels，effects of slow controlled-release fertilizer and planting density on yield and agronomic traists of nontilling maize variety Guixing planted on the rice field were studied. The results showed that yield of 6 treatments were more then 12 000 kg per hectare，which were A4B3，A4B4，A3B3，A3B4，A4B2 and A3B2. A3B3 treatment（fertilizer of 600 kg/hm2，planting deasity of 57 000 plants/hm2） was suggested the best treatment according to yield，agronomic traits and fertilizer input.
