Gainful Foliar and Seed Coating Applications of Carbon Nanotube in Pea (Pisum sativum L.) Crop | Asi

During two consecutive winter growing seasons, a field study was conducted to assess the response of garden pea (Pisum sativum L.) cv Master B to carbon nanotube (CNT) applied as a foliar spray or seed gill-coating pretreatment. The seed coating was applied at 50, 100, and 150 parts per million (ppm). Starting at the third true leaf level, the foliar spray was applied three times at week intervals at 100, 150, and 200 ppm.Furthermore, seeds that had not been handled or that had only been gill-coated were included. In general, treated plants outperformed both control treatments in terms of total green pod yield, total chlorophyll, days to 50% flowering, weight of 100 seeds, average green-pod weight, and total number of green pods per plant in both growing seasons. There were inconsistencies in the differences between untreated and merely gill-coated plants. Plants sprayed with 150 ppm CNT or grown from seeds coated with 50 to 100 ppm CNT provided the highest total green pod yield of pea.In the first and second seasons, the increased average green pod yield of the sprayed plants was 125 percent and 154 percent, respectively, compared to the untreated pea plants. In comparison to plants derived from untreated seeds, the use of 50 to 100 ppm CNT as seed coating pretreated increased total green pod yield by 72 percent in the first season and 171 percent in the second season. Total chlorophyll, days to 50% flowering, 100-seed weight, average green-pod weight, and total number of green-pods per plant all had a moderate to strong relationship with total green pod yield.CNT application using either method can be profitable in pea crop production, according to the findings. Seed coating, on the other hand, could be preferable because it complies better with biosafety and environmental sustainability concerns.
