Abstract:
Nano fertilizers are synthesized or modified form of traditional fertilizers by different chemical, physical, mechanical or biological methods with the help of nanotechnology used to improve soil fertility and productivity of agricultural produces. Nanostructure fertilizer exhibits novel physico-chemical properties, which determines their interaction with biological substances and processes. The study entitled was carried out in three parts, (i) Synthesis and characterization of nano NP and nano P fertilizers, (ii) optimization of nano NP and nano P fertilizers dose for wheat under in vitro and (iii) in green house study with using pots of 13 kg capacity of soil at Anand Agricultural University, Anand, Gujarat during 2021. In laboratory, the nano NP and nano P fertilizers were synthesized of different concentrations viz., 0, 500, 1000, 2000, 3000 and 4000 ppm by using direct precipitation method. The in vitro experiment conducted in laboratory was comprised of six levels of nano NP (0, 500, 1000, 2000, 3000 and 4000 ppm) and nano P (0, 500, 1000, 2000, 3000 and 4000 ppm) with 36 treatment combinations laid out in factorial completely randomized design (FCRD) with three repetitions. The greenhouse experiment was carried out based on the in vitro study. From the in vitro study, seed treatment of NP₃ + P₂ (nano NP @ 2000 ppm + nano P @ 1000 ppm) was found optimum dose for the wheat seedlings in terms of growth parameters. The results of greenhouse experiment reveled that foliar fertilization of NP₃ + P₂ (nano NP @ 2000 ppm + nano P @ 1000 ppm) and NP₄ + P₂ (nano NP @ 3000 ppm + nano P @ 1000 ppm) was found better at 21, 35 and 60 DAS than rest of the treatments in terms of growth, dry matter yield, nutrient content and uptake by plant.
