Evaluation Diversity of agricultural plants and Effectiveness of management factors in Non-hunting of Gharaviz
Abstract
Biodiversity is the basis of agriculture. sustainable agriculture both promotes and is enhanced by biodiversity. During present study, agrobiodiversity and management factors were investigated in three villages of Gharaviz area and four villages in surroundings area, in Sarpole-Zahab County. Interested data were collected via farms reconnaissance and visitation and special questionnaires. Species richness index, Shannon - Wiener and Simpson's dominance is calculated. Results suggested Species existed in study area are belonged to seven families among them poacea, fabaceae and solanaceae have the highest contribution. Species of wheat and corn are cultivated in all of rural area. Correlation between farm type to species richness indices (0.429**), Shannon-Weiner (0.449**) and dominance Simpson index (-0.315**) was significant, in other words, dry farming or irrigated farm have been affected afore mentioned indices. Correlation between fertilizer application way with species richness indices (-0.413**), Shannon-wiener (-0.377**), and dominants index of Simpson (0.296**) also was significant. The more tendency and application of chemical fertilizers, the less crops biodiversity will be. Correlation between organic fertilizers application to species richness indices (0.452**), Shannon-Weiner (0.419**), and dominants index of Simpson (-0.338**) was significant that as organic fertilizer increases, crop biodiversity also increases. Also effect of chemical fertilizers application, fallowing, using cultivations instruments and machines, using selected seeds, chemical herbicides and biological input on biodiversity indices have been insignificant.
