Abstract:
The use of agrochemicals in excessive amount negatively affect the soil nutrients, biotic community and soil fertility which directly affect the plant health, so it is necessary to develop the eco-friendly methods. Nanotechnology is the latest technique which led to numerous innovations in the agriculture sector to improves the nutrient availability leading to better yield and quality of crops. The nanobiofertilizers
are the combination of nanoparticles and PGPR, having phytostimulatory impact on plants growth. These PGPRs improve plant health by various mechanisms such as nitrogen fixation, phosphorus solubilization, nutrient availability and production of plant hormones. Similarly, the
nanoparticles of metals and their ions play important role in plant growth. the current study deals with green synthesis of zinc nanoparticles by using Azadirachta indica. The PGPR include in current study are Bacillus bingmayogenesis (KH3),Bacillus tropicus (LS5)], Achromobacter denitrificans (HS4) and Pseudomonas sp., (AH2)]. The Green synthesiszed zinc nanoparticles with above mentioned
PGPR were applied on Zea mays in randomized complete block design. A controlled treatment was also given to Zea mays without any nanoparticles and PGPR. The treated plants showed significant increment in shoot length, root length, number of leaves, fresh weight, protein content and chlorophyll content of Zea mays L. as compared to control which indicated that nano-biofertilizers treatment is more efficient, effective and environment friendly strategy and can be utilized for sustainable agriculture as cost effective strategy.
