 ABSTRACT

The experiment was conducted by Krishi Vigyan Kendra, Jajpur in collaboration with IFFCO, Jajpur in the farmer,s field of village Dihakuransa, Block Rasulpur of Jajpur District of Odisha  to study the effect  of Nano fertilizers on growth, yield  and economics of Tomato variety Arka Rakshak in Rabi season 2019. The experiment was laid out in randomized block design (RBD) with five treatments and five replications. Treatments involved were T1 - Farmers Practice (FP) ( 100% NPK + 100 % Zn application ), T2 - FP (50% N+100% PK+100% Zn ) + two sprays of Nano N  , T3 – FP (100 % NPK + 50 % Zn ) + two sprays of Nano Zinc, T4 – FP (100% NPK + 100% Zn) + two sprays of Nano Cu) , T5 - FP ( 50 % N + 100 % PK + 50 % Zn ) + 1st spray Nano N + 2nd spray Nano Zn + 3rd spray Nano Cu @ 4ml / lit water each. First spraying was done 20 days after transplanting, 2nd spraying at 15 days after 1st spraying and 3rd spraying was done 10days after 2nd spraying. From the experiment it was observed that application of  T5  produced maximum plant height (122.45cm), No. of branches per plant (12.4), fruit length (7.15cm), fruit girth (5.32cm), maximum number of fruits per plant (64.03), individual fruit weight (66.48g) and highest Yield per ha. (425.24q) followed by T2 (414.32 q/ha), T3 (409.28 q/ha) and T4 (407.42 q/ha). Lowest yield was found in T1 (398.20 q/ha) where RDF was 175:150:175 kg NPK per ha. Application of T5 ie. FP (50 % N + 100 % PK + 50 % Zn) + 1st spray Nano N + 2nd spray Nano Zn + 3rd spray Nano Cu recorded highest gross income of Rs 2,12,620 / ha with net return Rs 1,59,720 / ha and maximum benefit cost ratio 4.01. N- Nitrogen, P- Phosphorus, K- Potash, Zn- Zinc, Cu-Copper.
