A sustainable study of nutrient management using different combinations of organic and inorganic fertilizers for enhancing Wheat productivity

Wheat is a significant cereal crop which play a crucial role in the global nutritional and food security. So nutrient management strategy for the crop is of uttermost importance. Hence, the present study was designed to provide the optimized condition for Integrated Nutrient Management (INM) strategies on growth and yield parameters of wheat genotype WH 1124. The field experiment was carried out by using biofertilizer, vermicompost, and FYM (Farmyard Manure) with different doses of RDF (Recommended Dose of Fertiliser for N) for two rabi seasons 2021-2023 with 9 treatments (T1 to T9). The results revealed that the T4 (70% recommended dose of fertilizer + 2.5% Azospirillum + 2.5% phosphate-solubilizing bacteria + 20% farmyard manure + 5% vermicompost) has a significant effect on all growth and yield attributes, compared to the other integrated nutrient management (INM) treatments. The plant height under T4 varied significantly (29.9%) than T7 (70% RDF + 30% Vermicompost) and 6.13% greater than RDF. The maximum number of tillers recorded in T4, were 16.73% more than RDF. Compared to RDF, the spike length and LAI were 37.03 and 53.4%, higher, respectively. The maximum grain yield in T4 (47.4 q/ha) was 38.39% higher than RDF. Also, the maximum straw yield in T4 (62.7 q/ha) was 39.95% greater than the minimum straw yield recorded in T7. The study concluded that T4 treatment provided the optimized condition for sustainable integrated nutrient management of Wheat.
