تأثير كثافة الزراعة على نمو وحاصل نبات الكينوا

Abstract

This field experiment was made in a farm in the municipality of El Raqiba, El Oued State, on 30 November , 2021, to study the agricultural density on two cultivars of quinoa plants (chenpodiun quinoa willd.) which are va and vn with the dimensions (D1, D2, D3 and D4) which are 20cm, 30cm , 40 cm and 60cm, respectively, by sector design Spletplot with three iterations for each dimension for both cultivars, where we studied several criteria, including phenological (germination, flowers and seeds), morphological ( cabbage length , leg length, leg circumference and leaf area ), biochemical (chlorophyll A and B, sugars) and productivity (cabbage weight, seed weight in cabbage, weight of 1000 grains , seed yield). The obtained results showed that chenpodium (quinoa willd) when grown in different densities showed a response to high densities D1, D2 and medium densities D3 in the morphological critera and the productive criteria, but the category va gave better results than the category vn, both categories had better results at the high densities compared to the other crops ( Wheat, barley and maize), but at the low densities D4, the results were the opposite.
