Abstract:
Background and Objective: Food scarcity is one of the numerous challenges, encountered by the globe. Improvement in food production is highly demanded to overcome this issue. To increase maize production, soil fertility and productivity is required to be enhanced. The current study was designed to use integrated organic and inorganic fertilizers and polymers to improve soil conditions and increase the production of maize crop under the control conditions. Materials and Methods: Nine different treatments, i.e., T1 (Soil+Nitrogen), T2 (Soil+Potassium), T3 (Soil+Phosphorus), T4 (Soil+NPK), T5 (Soil+Compost), T6 (Soil+Polymer), T7 (Soil+(NPK+Compost), T8 (Soil+(NPK+Polymer) and T9 (control soil) were studied. Results: Results depicted that the highest production of maize crop in terms of harvest index (HI, 0.68%) and seed weight (109.64 g per cob) was found in T8 than all the other treatments. Similarly the physiological parameters such as Plant height, LAI, CGR, NAR were found significantly higher in T8 at all growth stages (20, 40, 60 and 90 DAS). Additionally, the crop water use efficiency was also improved by T8 treatment (22.7 kg h1 mm1). Conclusion: The study indicated that implementation of super absorbed polymer mixed with NPK fertilizer could play a better role to improve the soil condition and increase the productivity of maize. This may be due to its better of water holding capacity for longer period of time which could be beneficial for drought affected areas.
