Hey there Arjun Korah! When it comes to calculating the quantity of nano urea per hectare, it's typically done in kilograms. The calculation involves determining the amount needed based on the recommended application rate for effective results.

Regarding your second question, the quantity is generally calculated based on weight, considering the equivalence to conventional urea during the cost of cultivation calculation. This ensures a fair comparison and understanding of the economic aspects.

Now, diving into the cost of cultivation calculation you Arjun Korah provided:

1. Recommended Daily Nitrogen (RDN): 120 kg N (100%)

2. Treatment T2 involves 50% UREA + NANO N with 2 sprays at 4 ml/lt. of water. One bottle of Nano Urea is considered equivalent to 45 kg of conventional urea. Therefore, 60 kg of N is applied through Nano urea in this treatment.

To find the total nitrogen applied in the T2 treatment, you Arjun Korah sum up the nitrogen from conventional urea and Nano urea: 45 kg (urea) + 60 kg (Nano urea) = 105 kg.

If you Arjun Korah have any more details or need further clarification, feel free to ask.

According to the law of conservation of mass, nanourea molecules will produce exactly the same amount of protein in biomass as conventional urea. I believe nanourea may dissolve more slowly and be carried into groundwater. When used correctly and in a timely manner, these two substances are the same.
