[#189] Find the Rice equivalent yield of a system where, Rice yield = 6 t/ha, wheat yield 40 q/ha, price of rice Rs. 30,000/ton and price of wheat is Rs. 2,000/qt.
Correct Answer

(B) 8.66 t/ha

Explanation

Solution: Rice equivalent yield is calculated to compare system performance by converting the yield of non-rice crops into equivalent rice yield on a price basis. Formula: REY = Yx (Px/Pr) Where, Yx is the yield of non-rice crops (kg/ha) = 4,000 kg/ha of wheat Px is the price of non-rice crops (Rs. per kg) = 2,000 per qt Pr is the price of rice (Rs. per kg) = 30,000 per ton Here, REY = 8.66 t/ha
