Abstract

Grapes constitute a widely grown fruit in Afghanistan. Grapes can be grown just in anywhere but mostly in Kabul, Parwan, Kandahar, Zabul and Ghazni provinces. In Afghanistan there are three local varieties that offer the best commercial return for export: Shindokhani, Kishmishi and Taifi. New commercial varieties are also being introduced, such as Thompson Seedless and Red Globe, and are beginning to make inroads into foreign markets. The present study estimates the growth rate and instability of area, production, productivity of grape in top five provinces and Afghanistan as a whole during years 2011-12 to 2019-20. To analyse the growth rate and instability of area, production and productivity of grape, the statistical tools like Compound growth rate (CGR) and Coefficient of Variation (CV) were used. The result of the study showed that, the CGR for production in the Kandahar and Ghazni provinces were found positive and significant. While negative growth rate were found in Kabul, Parwan and Zabul provinces. The instability of production and area were very high in Kandahar province compare to the other selected provinces.

阿富汗葡萄种植面积、产量和生产力的生长与不稳定
葡萄是阿富汗广泛种植的一种水果。葡萄可以在任何地方种植,但主要是在喀布尔、帕尔万、坎大哈、扎布尔和加兹尼省。在阿富汗,有三种当地品种为出口提供了最好的商业回报:Shindokhani、Kishmishi和Taifi。新的商业品种也被引进,如汤普森无籽和红地球,并开始进入国外市场。本研究估算了2011-12年至2019-20年阿富汗五大省和整个阿富汗的葡萄面积、产量和生产力的增长率和不稳定性。采用复合生长率(CGR)和变异系数(CV)等统计工具分析葡萄的生长速率和面积、产量和生产力的不稳定性。研究结果表明,坎大哈省和加兹尼省的生产CGR为正而显著。而在喀布尔、帕尔万和扎布尔省则出现了负增长。与其他选定的省份相比,坎大哈省的产量和面积的不稳定性非常高。
