Many times crops fail to produce optimum yields in spite of proper nutrient supply. Physiological inefficiency in plants is responsible for such effects.

Plant Growth Promoters are those substances used for better management of Nutrients and Plant growth. These Plant Growth Promoters play a major role in seed germination, fruit ripening, enhances uptake of nutrients, boost protein synthesis, augment immunity and helps to withstand stress conditions, reduce flower and fruit drop and help in better plant growth.

Commonly plant growth regulators are auxins, gibberellins, ethylene etc.. There is growing interest in Natural alternatives. Below is the list of Plant Growth Promoters also called as Bio Agri inputs based on ingredients of Biological origin.
