Abstract

To evaluate the effect of irrigation treatments and integrated manure and chemical N fertilizer on baby corn yield, an experiment was carried out in Ramin Agriculture and Natural Resources University of Khuzestan, at summer and autumn 2015, in a strip plot design with four replications. In the experiment, three irrigation treatments (full irrigation and two limited irrigation treatments) were placed in length strips and six integrated fertilizer treatments were placed in width strips. Irrigation and fertilizer levels affected plant height, stem diameter, leaf numbers per plant, length of ear with sheath, diameter of ear with sheath, weight of ear with sheath, baby corn yield and harvest index, significantly. Integrated fertilizer treatment with full irrigation of furrows had higher baby corn yield, in comparison with other treatments. In limited irrigation treatments, N chemical fertilizer had more yield than the others. Therefore, integrated fertilizer treatments caused to decrease the yield of baby corn in limited irrigation fertilizers.
