To increase crop yield and soil fertility, crop producers use agricultural chemicals and artificial fertilizers. As a result plants become prone to fertilizer and soil infertility increases. A substitute to inorganic fertilizer could be biofertilizer. Biofertilizer is very beneficial for plants as it promotes growth and yield of plants without causing any ecological imbalance. The present investigation has been carried out to access the cytological effects of fertilizer urea and biofertilizer agrozyme on root tips of Trigonella foenum graecum L. It has been found that fertilizer turns out to be more chromotoxic and mito-inhibitory at higher doses in comparision to biofertilizer. High concentrations caused gradual decrease in mitotic index in case of fertilizer while in case of biofertilizer mitotic index is increased parallel to the increasing doses. Various chromosomal abnormalities were also observed at high concentration. In case of biofertilizer the abnormalities were lesser in comparison to fertilizer. The treated system showed various cytological irregularities viz. stickiness, precocious movement, unorientation, bridges, and forward movement. Although both share common range of aberrations but stickiness is predominant among them.
