Impact of nano slow-release fertilizers on growth and sustainable productivity of field crops

The prepared nanofertilizer loaded with carbon nanotube was subjected to thermogravimetric analysis to assess its nitrogen released pattern. The in-vitro incubation was performed for forty days at field moisture condition to study the nutrient contents release rate of the developed nanofertilizer and compared with convectional chemical fertilizer. A pot experiment with ‘Habanero’ pepper plant was performed to study the efficiency of the developed nanofertilizer in the growth advancement of ‘Habanero’ pepper. The post effect of the developed nanofertilizer application in the soil was also conducted. The release pattern of nitrogen from both developed nanofertilizer and conventional fertilizer showed a significant reducing tendency with time while the release of nitrogen contents was high-rise for the developed nanofertilizer than conventional one. The analysis of pot experiments showed a higher accumulation of nitrogen contents in the plant grown with the developed nanofertilizer compared to the convectional fertilizer. The post effects of fertilizers application in the soil revealed a better pH, moisture, cation exchange capacity, and nitrogen available under soil treated with the developed nanofertilizer was higher compared with the soil treated with the conventional fertilizer. The developed nanofertilizer therefore, potentially improved the nutrients contents use efficacy and positively influenced in crop growth enhancement.
