Abstract
The present research entitled “Performance of different varieties of potato (Solanum tuberosum L.) under Marathwada conditions” was carried out at Experimental farm, Horticulture Research Scheme (Vegetable), Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during Rabi season of 2021-2022, to evaluate the performance of six promising potato varieties for growth, yield and quality parameter under Marathwada conditions. The experiment was laid out in a Randomized Block Design with four replications and six varieties (treatments): Kufri Garima (T1), Kufri Frysona (T2), Kufri Pukhraj (T3), Kufri Lauvkar (T4), Kufri Jyoti (T5) and Kufri Chipsona-1 (T6). There was significant variation observed among the varieties with respect to growth, yield and quality parameters of potato.
The plant emergence percentage was reported highest in Kufri Pukhraj-T3 (93.07%) at 30 DAP. The maximum number of shoots per plant was found in Kufri Lauvkar (T4) was (7.02) at 30 DAP. The plant height increased linearly up to 90 DAP and Kufri Jyoti (T5) reported maximum plant height at 60 and 90 DAP (53.25 cm and 56.48 cm respectively). Maximum number of leaves per plant was reported in Kufri Frysona (T2) (73.77) at 90 DAP. Kufri Jyoti (T5) measured highest leaf length at 90 DAP (8.20 cm). The maximum leaf width was found in Kufri Pukhraj (T3) at 90DAP (4.83 cm). The number of stolon per plant was maximum (22.25) in Kufri Pukhraj (T3).
The minimum number of days required for maturity (80.85 days) was observed for Kufri Lauvkar (T4). Kufri Pukhraj (T3) recorded the more number of tubers per plant (13.25). Kufri Chipsona-1 (T6) had the maximum tuber diameter (6.25 cm). The maximum tuber length (10.75 cm) was found in Kufri Chipsona-1 (T6). The maximum (759.57 g) weight of tuber per plant was reported in Kufri Chipsona-1 (T6). Kufri Pukhraj (T3) reported significantly maximum tuber yield (14.27 kg/plot and 297.40 q/ha).The maximum B:C ratio 2.41 was observed in Kufri Pukhraj (T3).
The minimum number of plants affected by late blight incidence (5.62%) was recorded in Kufri Pukhraj (T3) while minimum number of plants affected by aphids was recorded (17.50%) in Kufri Pukhraj (T3).
Among varieties Kufri Pukhraj (T3) recorded highest TSS content (6.27 0Brix) and Kufri Chipsona-1 (T6) recorded maximum dry matter (22.81%). The highest specific gravity (1.19 g/cm3) was found in Kufri Chipsona-1 (T6). The highest starch content (23.42%) was found in Kufri Chipsona-1(T6). The variety had maximum volume of tuber (165.10 ml) was Kufri Chipsona-1 (T6).
The present study revealed that the existence of significant variability among the different potato varieties in their growth, yield and quality parameters. Kufri Pukhraj (T3) recorded maximum profitability due to its higher farm gate price. Among all the varieties Kufri Pukhraj and Kufri Jyoti have potential to grow successfully and will sustain farmer’s income under Marathwada conditions.
