**2.7 Crop geometry**

Crop geometry is an important aspect which influences proper sunlight interception which leads to optimum physiological activities of plants. Optimal plant population aids in proper translocation of photosynthates in the plant. In case of higher than optimum plant population, competition for water, space, light, and nutrient increases which results in reduced accumulation of dry matter in plants. Therefore, optimum plant geometry is an important requirement to realise higher production of crops [13, 14]. Crop geometry in case of cumin within row spacing of 22.5–30 cm, within plant spacing of 15–30 cm.
