Abstract

Potato crop is the highest yielding vegetable in world as well as India. The prevalence of prices fluctuation of potato market is a common phenomenon due to seasonality and biological nature. This intricate interplay leads to substantial variations in potato output, consequently causing fluctuations in prices. So, the present study was conducted with seasonal variation and correlation between market arrivals and price of potato in Deesa market of Banaskantha district. The time series analysis of potato prices and arrivals was conducted in Deesa market for the period 2011-12 to 2020-21. The finding indicated that, the seasonal indices of arrivals reached their maximum during the harvest season and correspondingly decrease during the post-harvest seasons. Seasonal indices of prices decreased in harvest season and when the arrivals decreased, price increased in post-harvest season. Similarly, negative correlation found between the arrivals and prices of potato in certain year, indicating that prices of potatoes were independent on market arrivals in the regulated market.

古吉拉特邦巴纳斯坎塔地区马铃薯季节指数及市场到货与价格的相关性

土豆是世界上产量最高的蔬菜，也是印度产量最高的蔬菜。马铃薯市场普遍存在的价格波动是由于季节性和生物性的原因造成的一种普遍现象。这种错综复杂的相互作用导致马铃薯产量的巨大变化，从而引起价格的波动。因此，本研究对Banaskantha地区Deesa市场马铃薯到货量与价格的季节变化及相关性进行了研究。对2011-12年至2020-21年期间Deesa市场马铃薯价格和到货量进行了时间序列分析。结果表明，季节指数在收获季节达到最大值，收获后季节相应降低。收获期价格季节性指数下降，收获期后价格随到货减少而上升。同样，某年马铃薯的到货量与价格呈负相关，说明在管制市场上马铃薯的价格与到货量无关。
