Abstract

: Lab experiment was conducted in the Department of Agronomy in the year 2023 to study the effect of seed treatment with nano DAP on germination and seedling growth of seven crops viz., rice, wheat, maize, oats, soybean, mustard and gram. The experiment consisted of seven treatments which were tested incompletely randomized design with three replications. Germination percentage and seedling growth indices varied significantly with seeds treated with nano DAP@ 5ml/litre resulted in maximum germination percentage, higher seedling length as well as seedling dry weight and were found at par with nano DAP @ 2.5 ml/litre and significantly higher over other treatments. On the basis of this study it can be concluded that nano DAP has great potential in improving germination, emergence and seedling vigour. Treating seeds with nano DAP @ 2.5 ml/litre or 5 ml/litre enhanced seed germination, seedling indices and seedling vigour index but further increase in nano DAP concentration beyond 5 ml/litre might have adverse effect on plant growth

Conclusion

Significantly higher germination percentage, seedling length as well as seedling dry weight was recorded with treatment in which seeds were treated with nano DAP @ 5 ml/litre though this treatment was at par with nano DAP @ 2.5 ml/litre seed in all the crops. Further increasing the concentration of nano DAP in the solution made for treating the seeds above 5ml/litre (7.5,10.0, 12.5 and 15 ml/litre) significantly lowered the germination percentage. On the basis of this study it can be concluded that nano DAP has a great potential in increasing the germination of different crops as well as ensuring early seedling vigour which might result in better crop productivity. Also the seed treatment with nano DAP should be done at dose of 2.5-5 ml/litre
