ABSTRACT

 

During the past few decades, significant achievements have been made to increase the food production to meet the ever increasing need of human population. The agricultural practices includes high yielding varieties, excessive use of chemical fertilizers, pesticides, heavy irrigation etc. has resulted imbalance of ecosystem including soil erosion, nutrient deficiencies, loss of organic matter and ultimately loss in agricultural productivity. The concept of biofertilizer solid as well as liquid formulations needs to be popularized in a large way. Liquid technology is emerging as promising future and more efficient and result oriented. The present communication deals with the effect of crude extract of algae on the growth and yield of brinjal (Solanummelongena L.). Six treatments of different concentration were used. Marked response was observed in morphological and biochemical constituents of the treated plants with (20%, 40%, 80% and 100%) concentration against the control (i.e. untreated plant). The morphological parameters- plant height, leaf size, flowering, fruits per plant, and fruit index was studied. The biochemical estimations of proteins, carbohydrates, crude lipids, ascorbic acid, were also found to be significantly increased. Chlorophyll-a, chlorophyll-b and carotenoid contents in the treated plant leaves were also found to be increase as against the control plants. The algal extract favors early and increased numbers of flowers and final fruit setting, also early harvesting as compared to the control plants.
