Abstract :
In order to investigate the effects of manure and application of Nitroxin fertilizer accompanied by gibberellin on corn (Zea mays L.) in Baiza (Fars province), a split factorial experiment arranged in randomized complete blocks design (RCBD) was conducted with three replications. Treatments included manure(zero and 30 t ha-1) and Nitroxin fertilize (zero and 35 g a.i/ha-1) rrespectively, each at two levels as main plots and three levels of gibberellin (zero, 100 and 200 ppm) were as sub-plots. Results showed that the effect of their interaction was not significant on many traits and characteristics but significant for single effect. The highest traits related to application of different levels of manure were obtained in treatment of 30 t of manure per hectare. The results related to Nitroxin fertilizer application of 35 g/ha-1 increased many traits. Gibberellin increased the traits but among the levels of between 100 and 200 ppm significant difference wasn’t observed on some traits. The highest grain yield was obtained in treatment of 30 t/ha-1 of manure, Nitroxin fertilizer the rate of 35 g/ha-1 plus 100 ppm gibberellin .Results showed that current conditions and the development of sustainable agriculture, use of these inputs can be beneficial and justified.
