8.4.2 Crop Efficiency This analysis was performed in order to figure out which blocks are performing poorly in comparison to their neighbors. It was determined based on individual area as well as yield rate of each type of crop in each block using the formula which was mentioned below;

Agriculture Efficiency (Ei) =

Iij = * 100

whereas

Iij = ratio between the yield of any crop (Yij) of the individual area ‘i’ under the total area and the average yield rate (Yi) of the entire area ‘y’ of any crop x 100.

Cij = Area in percentage (%) for individual crop in individual areal unit.

Sample Calculation – Aska Block

Firstly, percentage area, yield(productivity) rate (in Qntl/ha) of each crop in Aska block was calculated (Figure 8.10). Then average yield of each crop in all the blocks is calculated (Figure 8.12)

Likewise, the calculation was carried out for all the blocks (Figure 8.11 and 8.12)

Then, Iij was calculated using Yij and Yij, summation of both Cij and Iij was carried out then those are used for calculating Agriculture Efficiency (Figure 8.13).

Similarly, Iij and Cij was computed for all the blocks and determined efficiency values for each block (Figure 8.14).
