Study of Shade Net Cultivation Compared to Open Field on Yield of Potato Varieties (Solanum tuberosum L.)

Abstract

A field experiment was conducted at the potato research station, Mainpat, Surguja (C.G.) during Rabi season 2021-22 with a view to study the “Study of shed net cultivation compared to open field on yield of potato varieties (Solanum tuberosum L.)”. The field experiment was carried out in split plot design with three replications. The soil of experimental field was sandy clay soil. The investigation, There were the recommended dose of fertilizer NPK kg ha-1 was applied at different concentrations in potato with two production system (Main plot) i.e., P1- Open field and P2- Shed net house and four potato varieties (Subplot) i.e., V1-KufriKhyati, V2-Kufri Lalit, V3-KufriChipsona- 3, and V4- True Potato Seed (F2C2) which were interaction effect of potato. The yield attributes of potato i.e. number of tubers plant-1, fresh weight of tubers plant-1 (g), tuberization efficiency (tuber: haulm), grade wise tuber yield i.e.<50g, 50-100 g &>100 g, total tuber yield and haulm yield of potato were significantly superior in shade net house growing system (P2) with Kufri Lalit (V2) variety. On the basis of above findings, among the different production system P2(Shed net house) followed by P1 (Open field) showed the best result for all the parameters. Amongst the different verity V2 (Kufri Lalit) followed by V3 (Kufri Chipsona-3) recorded best result for all the parameters. However, interaction effect of variety with production system P2V2(Shed net house and Kufri Lalit) followed by P2V3(Shed net house and Kufri Chipsona-3) noticed best result for all the treatments of yield parameter.
