Effect of Nano Urea on Growth and Yield of Potato in Lower Gangetic Planes of West Bengal

Abstract

In today’s world it is the need of the hour to adopt new technology to sustain the production of future. Nano technology is gaining popularity for its efficiency over various applied field of science. In agriculture the nano materials have a huge impact on efficiency of fertilizer pesticides etc. As it requires in very less quantity and has a negligible residual effect the environment is safe with the innovation of Nano fertilizer. Keeping this view into account an experimental Trial at farmer’s field was carried out at Berui village in Hooghly District of West Bengal during the winter (rabi) season of 2019 – 20 under the supervision of Berui Cooperative, KVK-Hooghly, BCKV and IFFCO with nano-Urea, nano-Zn and nano-Cu using RBD design with 10 treatments and 3 replications. Experimental results revealed that highest tuber yield was obtained in T-7 (50% N+100% P & K+ 2 spray of nano-Urea), and that was followed by T-10 (50% N + 100% P & K + 50% Zn + 1 spray each of Nano-Urea, Zn and Cu) and T-8 (100% N-P-K + 50% Zn + 2 spray of Nano-Zn). The performance of nano fertilizers, Nano- Urea, was quite promising and economically viable as compared to 100% recommended dose with commercial fertilizers (RDF).
