Assessment Effect of Super Absorbent Polymer and Nitroxin on Growth Curves and Corn (Zea mays L.) Production

BACKGROUND: Nutrient management plays an important role for obtaining satisfactory yields and to increase crop productivity. Also keep soil moisture under drought stress is an important factor to produce economical production, so super absorbent polymer has great role to achieve mentioned goal. OBJECTIVES: Present study was conducted to evaluate the effect of different level of super absorbent polymer and Nitroxin biological fertilizer on the productivity of maize and growth Indices. METHODS: Current research was carried out according factorial experiment based on randomized complete blocks design with three replications during 2015-2016. The first factor included different level of Super Absorbent Polymer (S1= nonuse of super absorbent polymer or control, S2= 100 kg.ha-1 and S3= 150 kg.ha-1 super absorbent polymer) and second factor included three level of Nitroxin (N1= nonuse of Nitroxin or control, N2= 1 L.ha-1 and N3= 3 L.ha-1 Nitroxin). RESULT: Result analysis of variance revealed effect of super absorbent polymer and Nitroxin on seed yield and biologic yield was significant but interaction effect of treatments was not significant. According result of mean comparison of different level of super absorbent that maximum seed yield (8455 kg.ha-1) biologic yield (13266 kg.ha- 1), Leaf area index (3.5), Leaf area ratio (0.0035 m2.gr), Relative growth rate (0.09 gr.gr-1.day-1), crop growth rate (35 gr.m-2.day-1) 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 characteristics observed for 1 L.ha-1 treatment. CONCLUSION: Finally according result of current research consume of 150 kg.ha-1 Super Absorbent Polymer and 1 L.ha-1 Nitroxin led to produce highest corn yield and growth indices and it can be advised to farmers in studied region.
