Abstract:
An experiment was conducted to find out the suitable organic, inorganic nutrients and biofertilizers or their combinations for integrated nutrient management in tomato at the Horticulture Research Farm, College of Agriculture, Indore (M.P) during kharif season of 2019-20. The experiment comprised of total eight treatments combinations of organic and inorganic nutrients and control. The experiment was laid out in randomized completely block design with three replications. Application of RDF treatment T₂-100% RDF (100:50:50 NPK respectively) recorded significantly best performance over plant height (114.03 cm) phonological parameters like minimum days taken into first flowering (41.67), days taken to 50% flowering (54.43), days to first fruit picking (82.07), fresh weight of plant (169.12 g) and dry weight of plant (57.22 g). Similarly, treatment T₈ (RDF 75% + 25% [Neem cake (6.25%) + Vermicompost (6.25%) + FYM (6.25%) + Poultry manure (6.25%)] + PSB + Azotobacter,) recorded superior performance over other treatment for growth and yield parameters like maximum number of branches per plant (25.67), number of leaves per plant (77.93), leaf area (360.58 cm²) at harvest stage, and maximum number of fruit per plant (44.13), polar diameter (5.52 cm), equatorial diameter (4.93 cm), fresh weight of fruit (65.89 g), dry weight of fruit (3.64 g), fruit yield (19.40 kg/plot) and fruit yield (269.44 q/ha). The minimum values of all parameters were recorded under control.
