Abstract
With increasing demand on agricultural production there is an increasing trend in excessive use of chemical fertilizers and pesticides. These chemicals do not degrade easily and can have severe side effects. Lot of studies have highlighted the impacts and have prompted for more sustainable alternatives. Organic fertilizers and pesticides have been developed and studied for potential effects on productivity. Recently bio fertilizers have been developed which use microbial and enzyme based pathways to promote plant growth and development. The current study focuses on effect of bio fertilizers from fish waste on chlorophyll content and plant growth in Cicer arietinum. Chlorophyll a, b and Total chlorophyll were calculated using the (Arnonâs 1949) method. The chlorophyll a content was similar in control and samples (0.588 to 0.650). The highest value is for 0.645 is for commercial fertilizer. While similar trend was visible for chlorophyll b with values ranging from (1.006 to 1.190) with commercial fertilizer getting the highest value 1.180.Total chlorophyll content was also comparable to control. Though commercial fertilizer had a slighter higher chlorophyll value enhancing potential but has very poor germination rate hinting towards potential toxicity of the same.
