2.7. Quantification of Yield Data

Plant height was measured by a meter scale of 100 cm. The plants were cut from the ground level. The height of five plants was measured from the base to the tip of the main shoot, and the height of the five plants was averaged. All pods from the five sample plants were counted, and the average value was taken. The pod having at least one seed was counted as a filled pod and the pod having no seed was counted as an unfilled pod. Pod length was measured on a small scale of 30 cm. After collecting all the pods, ten pods were selected randomly, the length was measured, and the mean value was recorded. After separating the seeds from the pods, they were counted by hand. Then, the average value was recorded. Weight of 100 seeds was recorded for each variety treatment-wise. Total seeds from a 1.8 m² area were weighed by an electrical balance. The weight of seeds was converted to t ha⁻¹. The moisture content of seeds was measured using a digital moisture meter and adjusted to 14% moisture using formula (1).

where W is the fresh weight, and M₁ and M₂ are the fresh and adjusted moisture percent of the grain, respectively.

For taking straw yield, a 1.8 m² area was harvested, and seeds were separated. The plant stems were dried, and straw was recorded and converted to t ha⁻¹. Harvest index (HI) was determined using the following Formula (2):
