Abstract:
A study was conducted at the Research Farm of ICAR-CPRI-RS, Maharajpura, Gwalior (M.P.) during kharif, rabi and summer season of 2018 and 2019 to investigate the effect of plastic mulching and drip irrigation on physiological parameters of potato (Solanum tuberosum L.) varieties under potato-based cropping system. The study involved eight treatment combinations replicated four times in split plot design. The treatments comprised of four mulching viz. DM₁: Drip irrigation with black-black plastic mulch, DM₂: Drip irrigation with silver-black plastic mulch; DM_3: Drip irrigation without mulch; FI₄: Farmer’s practice (Check) and two varieties viz. V₁ Kufri Badshah and V₂: Kufri chipsona-3. Physiological parameter can be used to account growth in terms of functional or structural significance. With respect to root: shoot ratio, CGR, RGR and AGR, the two cultivars as well as different plastic mulching showed different trend at different growth stages of the crop. The performance of Kufri Chipsona-3 under silver black plastic mulching with drip irrigation remained superior to other treatment combinations. However, this treatment remained at par with performance of Kufri Badshah under drip irrigation with black-black plastic mulching. A non-significant interaction for SPAD meter reading was found between plastic mulching under drip irrigation and potato cultivars at all growth stages during both experimental year and on pooled basis.
