“…It showed the mitodepressive activity of magnesium sulphate. Similar result were obtained by Abraham and Nair (1989) in vicia faba. The reduction in mitotic activity may result from a blocking of G1 stage suppressing DNA synthesis (Mohandas and Grant 1972).…”

The mitotic activity and chromosomal behaviour was observed in four different concentrations of magnesium sulphate at four different duration of treatment using Allium cepa as a biological system. Mito-inhibitory effect of the compound was observed in higher concentration. The compound was capable of producing various chromosomal abnormalities indicating the cytostatic and clastogenic properties of magnesium sulphate.

“…Ammonium sulphate was encountered to be mitodecelerating at higher doses, affecting normal mitotic cycle, probably by affecting various crucial enzymatic steps involved in the cellular responses. The mitodecelerating affect of fertilizers on AMI at higher dose was also reported by Abraham and Nair (1989) in Vicia faba, Bhatta and Sakya (2008) in Allium cepa. Tabur and Oney (2009) reported decline in mitotic index at elevated concentrations in Vicia hybrida.…”

The agriculture sector has circumpassed a massive revolution in the past few decades. Old conventional practices and modern innovative techniques have complemented each other well. Applications of fertilizers have increased the crop yield, but its higher concentration has offered detrimental effects. Farmers often exceed the prerequisite limit and this exaggeration denatures the soil and this aggravates various ecological repercussions. To tackle this complication, organic bio fertilizers have emerged as a sustainable, eco-friendly substitute and cost-effective approach. The objective of the present experimental setup is to investigate the effects of fertilizer ammonium Sulphate and biofertilizer agrozyme at the cytological level in the root meristems of barley and to trace out a safer crop enhancer between the two. Various concentrations of fertilizer and biofertilizer used were 50%, 100%, 150%, 200% each, along with a control set. Chromosomal studies revealed a considerable impact on Active mitotic index which depicted a consistent increment in the case of bio fertilizer, but appeared to decline at higher doses in the case of fertilizer, with respect to the control. Various chromosomal anomalies were observed, such as scattering, precocious movement, stickiness, fragmentation at metaphase and stickiness, laggard, unorientation, bridges etc. at anaphase. Percentage of these abnormalities was higher in the case of fertilizer. Conclusively, it is inferred that Bio fertilizers are mitotically accelerating and chromotoxically much safer as compared to fertilizers and should be promoted for agro-system to obtain sustainable crop improvement.

“…The lowering of AMI % can be attributed to inhibition of DNA synthesis at S-phase [13]. The mitodecelerating effect of fertilizers on AMI at higher dose was also reported by Abraham and Nair [14] in Viciafaba, Bhatta and Sakya [15] in Allium cepa. Chromosomal anomalies show intense increases in both the cases, but the chromosomal disturbance was more obvious in the case of APS.…”

The agriculture sector requires a revolutionary alternative that makes crop production high and elicits less ill-effects on the environment. At present, agriculture area facade the challenge of low yield of many agronomic crops which lead to economic losses. Experimentally, it is proved that fertilizer use can boost yield two three times more in spite of other factors unchanged. But surplus and unbalanced usage of these soil supplements like fertilizers and irrigation causes serious problems to our soils like water logging and formation of saline soils and ultimately lead to denatured soil. This situation can be alleviated through the use of eco-friendly biofertilizer. So the present appraisal scrutinizes the effect of fertilizer Ammonium Phosphate Sulphate (APS) and biofertilizer (Agrozyme) on the cytology, morphology and pigment constituents of the Foeniculum vulgare Mill. and to trace out a safer crop enhancer among the two. The results revealed that fertilizer expelled to be more chromotoxic and mito-inhibitory at higher concentration in comparison to biofertilizer. Fertilizer negatively affects the plant’s mitotic index while biofertilizer enhances mitotic index parallel to the increasing concentration. Biofertilizer shows positive effect on the germination, survival and plant growth while fertilizer shows this elevation effect at lower concentration. The biochemical constituents (photosynthetic pigments) are greatly affected by higher concentration of both the treatments. The treated system shows various anomalies such as stickiness, precocious movement, loop formation at metaphasic stage and stickiness, laggard and bridge etc at anaphasic stage. Since, biofertilizers area much safer as compared to fertilizers and it also enhances the qualitative and quantitative traits, therefore it could be used in agro-system to obtain sustainable crop upgradation.
