Abstract

A field experiment was conducted at the Department of Agriculture at Himalayan University, Jullang, Arunachal Pradesh, to assess the impact of composts and biofertilizers on plant growth. The available nutrient status was medium in N, High in P and medium in K. The treatments considered of T1- Control 100 % RDF, T2 - Vermicompost + Phosphorus solubilizing bacteria, T3 – Poultry manure + Azotobacter, T4 – Compost + Phosphorus solubilizing bacteria + Azotobacter, T5 – Compost+ Phosphorus solubilizing bacteria, T6 – Poultry manure + Azotobacter, T7 – Vermicompost + Phosphorus solubilizing bacteria + Azotobacter. The highest plant height recorded 20.87 at 20 DAS, 53.27 at 40 DAS, 124.67 at 60 DAS, 142.73 at 80 DAS and 193.73 at 100 DAS, highest number of leaves plant-1 recorded 4.80 at 20 DAS, 5.80 at 40 DAS, 7.44 at 60 DAS, 8.47 at 80 DAS and 12.60 at 100 DAS and plant dry weight recorded 6.23 at 20 DAS, 54.87 at 40 DAS, 122.00 at 60 DAS, 138.67 at 80 DAS and 159.33 at 100 DAS were obtained with treatment (T7) receiving Vermicompost + Phosphorus solubilizing bacteria+ Azotobacter. Some of the challenges we faced were slow and time-consuming in conducting research trail. Also faced difficulty in getting biofertilizers.

Conclusion

Considering the salient findings in perspective, the study revealed that application of Vermicompost with Phosphorus Solubilizing Bacteria and Azotobacter (T7) was found to be best combination for maximizing the growth parameters (plant height, Number of leaves plant-1 and plant dry weight) of maize. Treatments with Vermicompost and Phosphorus Solubilizing Bacteria was also observed best in CGR (g m-2 day-1) and RGR (g g-1 day-1) in treatment (T7).
