Bio Stimulant Activity of Protein Hydrolysate: Influence on Plant Growth and Yield
Journal Title: Journal of Plant Science and Research - Year 2015, Vol 2, Issue 2
Abstract
Fertilization practices and growing techniques play a major role in influencing plant productivity. Fertilizers which have minimum impact on the environment are gaining popularity. In this regard, organic bio-stimulants such as protein hydrolysates, humates, etc., are becoming popular, as they reduce the use of chemical fertilizer by up to fifty percent. In this study, we focus on the influence of protein hydrolysate of animal origin on growth and productivity of different crop plants. We observed a positive effect of protein hydrolysate on plant growth and yield across crop species. Both soil and foliar treatments had a higher impact on the initial plant growth compared to control; however, soil application was more effective than foliar application. All parameters recorded including root and shoot length, leaf area, total chlorophyll content, photosynthetic rate, and yield were greater in treated plants. We report here that, protein hydrolysate when supplemented through soil, positively influences plant growth and metabolism; thereby, contributing towards higher crop yields. Hence, protein hydrolysates can be effectively used as organic fertilizers to improve productivity of the crops.
