Influence of bio-stimulants on biomass production, soil properties and nutrient uptake by chilli (Capsicum annuum L.)

It is because of ability to support ecologically friendly and sustainable farming techniques, biostimulants are gaining more attention in contemporary agriculture. This research applied various concentration of protein based bio-stimulants on chilli. The aim of research was to find their best concentration, leading to maintain biomass production, soil properties and nutrient uptake. The experiment was in random complete block design in a research field at Indian Council of Agricultural Research Krishi Vigyan Kendra, Hadonahalli, Doddaballapura. The experimental treatments were commercial bio-stimulant (3 ml/L), seedling dip and foliar application of amino acid based bio-stimulants (2.5, 5, 7.5 ml/L) at vegetative, flowering and fruit development stage. Maximum fresh shoot weight (275.53 g), root weight (32.43 g), total biomass (308.99 g), dry shoot weight (86.03 g), root weight (20.00 g), total biomass (106.03 g) was observed with the combination of seedling dip along with foliar application of amino acid based bio-stimulants they had no significant influence on soil pH, EC and OC.
