Abstract

Today for improving the crop yield, organic and inorganic fertilizers are applied. Mostly chemical fertilizer are applied in greater extend to get faster result. The negative impact of chemical fertilizers includes chromosomal abnormalities in plants and also to the animals who consumes that crop. Panchagavya is an incredible source of growth promoting substances. Panchagavya is a term used in ayurveda to describe five important substances obtained from cow, which include cow’s urine, milk, ghee, curd and dung. In ayurveda all these five products possess medicinal properties against many disorders and are used for the medicinal purpose singly or in combination with some other herbs. Urea is one of the common fertilizer that enriches the soil with nitrogen. As nitrogen is a major component of chromosomes it is quite possible that the residues or metabolites of urea may cause some damage to them. Root initiation in between the panchagavya and urea fertilizer in Allium cepa was calculated. Number of roots in panchagavya and urea treatment was calculated. Mitotic index of panchagavya and urea fertilizer was calculated. Cytogenetic effect in panchagavya and urea was studied on onion bulbes. In 5% of panchagavya solution is favorable for root initiation. The mitotic index is higher in panchagavya solution than urea and control. There is no cytogenetic effect in panchagavya treated onion bulbs. But the abnormalities are shown in the urea treated onion bulb root tips. So finally the panchagavya is good eco friendly and good root initiator fertilizer.
