Evaluation Seed Yield, Its Components and Morphological Traits of Corn in Response of Consume Super Absorbent Polymers and Nitroxin

BACKGROUND: Super absorbent polymers (SAP) by increasing the capacity of water storage and nutrition materials, reduction of wasting water and evaporation from the surface of soil improve crop production under water stress condition. Bio-fertilizers have the significant advantages to chemical fertilizers; for instance, they do not produce toxic and bacterial substances in the food chain, are able to reproduce spontaneously, can improve the physical and chemical properties of the soil, are affordable economically and are acceptable environmentally. OBJECTIVES: This research is aimed to examine the changes of seed yield, its components and morphological traits of corn affected different level of SAP and Nitroxin bio-fertilizer. METHODS: Current study was carried out via factorial experiment based on randomized complete blocks design with three replications during 2015-2016. The first factor included different level of SAP (S1= nonuse of SAP or control, S2= 100 kg.ha-1 and S3= 150 kg.ha-1 SAP) and second factor consisted three level of Nitroxin (N1= nonuse of Nitroxin or control, N2= 1 L.ha-1 and N3= 3 L.ha-1 Nitroxin, used in stem elongation). RESULT: Result analysis of variance revealed effect of SAP on all measured traits (instead ear diameter, number of row per ear) was significant, also effect of Nitroxin on all measured traits (instead plant height, stem diameter, ear length, harvest index) was significant. Interaction effect of treatments on all measured traits (instead plant height) was not significant. According result of mean comparison of different level of super absorbent that maximum plant height (179 cm) stem diameter (2.5 cm), ear length (19 cm), seed yield (8455 kg.ha-1), biologic yield (13266 kg.ha-1), harvest index (60%), Number of seed per row (27), 100-seed weight (23 gr) was noted for use 150 kg.ha-1 super absorbent and minimum amount of mentioned traits was belonged to control treatment. Also between different level of Nitroxin the highest amount of measured traits observed for 1 L.ha-1 treatment. CONCLUSION: Generally results of current study indicated consume 150 kg.ha-1 SAP and 1 L.ha-1 Nitroxin led to improve seed yield, its components, harvest index and morphological traits from aspect economically and it can be advised to producers.
