Leaf area index (LAI) is a dimensionless quantity that characterizes plant canopies.It is defined as the one-sided green leaf area per unit ground surface area (LAI = leaf area / ground area, m 2 / m 2) in broadleaf canopies.In conifers, three definitions for LAI have been used: . Harvest index for different crops: For each crop, harvest index vary and for production of a crop per hectare on international basis, the value of H.I is fixed. Diversification: Access to crop diversification related extension advice such as minimum tillage, crop rotations and mixed cropping has a positive significant effect on crop diversification. When multiple crops are grown simultaneously, this is also known as intercropping.This cropping system helps farmers to double their crop productivity and income. D = 0.3 (Simpson's Index) Then: Simpson's Index of Diversity 1 - D = 0.7. JSTOR®, the JSTOR logo, JPASS®, Artstor®, Reveal Digital™ and ITHAKA® are registered trademarks of ITHAKA. The intensity of cropping, therefore, refers to raising a number of crops from the same field during one agricultural year. Since the FAO indices are based on the concept of agriculture as a single enterprise, amounts of seed and feed are subtracted from the production data to avoid double counting, once in the production data and once with the crops or livestock produced from them. The increase can be plotted as a logarithmic or exponential curve in many cases. D = 0.3 (Simpson's Index) Then: Simpson's Index of Diversity 1 - D = 0.7. Cropping intensity refers to raising of a number of crops from the same field during one agriculture year.
