The application of nanotechnology in agriculture has increased rapidly. However, the fate and effects various nanoparticles on soil, plants, humans are not fully understood. Reports indicate that exhibit positive negative impacts biota due to their size, surface property, concentration within system, species or cell type under test. In translocated either by apoplast symplast pathway both. Also, it is clear whether entering plant system remain as biotransformed into ionic forms other organic compounds. Controversial results toxicity nanomaterials available. general, nanomaterial was exerted producing reactive oxygen species, leading damage denaturation biomolecules. intensity cyto- geno-toxicity depends physical chemical properties nanoparticles.

Maize (Zea mays L.) is an important crop grown for food, feed, and energy. In general, maize yield decreased due to drought stress during the reproductive stages, and, hence, it critical improve grain under drought. A field experiment was conducted with a split-plot design. The main factor irrigation regime viz. well-irrigated conditions withholding from tasseling filling 21 days. subplots include six treatments, namely, (i) control (water spray), (ii) zinc oxide @ 100 ppm, (iii) manganese 20 (iv) nZnO ppm + nMnO (v) Tamil Nadu Agricultural University (TNAU) Nano Revive 1.0%, (vi) sulfate 0.25% 0.25%. During stress, anthesis–silking interval (ASI), chlorophyll b content, proline, starch, carbohydrate fractions were recorded. At harvest, grain-filling rate duration, per cent green leaf area, traits Drought increased proline (38.1%) (0.45 d) over irrigated condition. However, foliar application of ZnO (100 ppm) (20 lowered ASI index, content water spray. seed-filling (17%), duration (11%), seed (19%) Nevertheless, (90%), (13%), (52%) by spraying These findings suggest that significantly conditions.
