- Abstract
The present study was conducted to evaluate the performance of liquid, gel and carrier based formulations of Azotobacter chroococcum MAC- 4 on the growth and yield of maize var. Co 1 at graded levels of inorganic nitrogen fertilizer under field conditions. The liquid formulation of A. chroococcum MAC- 4 inoculation with 75 per cent N level enhanced the plant height (178.33 cm), dry matter production (259.03 g plant-1), yield components like no. of grains cob-1(483.67), grain weight plant- 1(146.45 g), cob weight plant-1(276.45 g), 100 seeds weight-1(28.49 g), grain yield (6.50 t ha-1) and stalk yield of maize (10.53 t ha-1)were recorded followed by gel and carrier based formulations of A. chroococcum MAC- 4. It was concluded that inoculation of liquid based formulation could augment the growth and yield parameters of tomato by fixing higher amount atmospheric nitrogen and secreting higher amount of plant growth promoting substances like Indole acetic acid (IAA) and Gibberellins' when compared to the gel and carrier based formulation in tomato crop.
