The Effect of Alternative Tillage Practices on Potato Growth and Yield

An experiment was conducted during the rabi seasons of 2021-22 and 2022-23 at the Research Farm, ICAR-Central Potato Research Station RS, Gwalior (M.P.). The experiment consisted of 7 treatments viz.; Farmer’s practice (T1), CIP Technique (T2), Regional AICRIP/INSTITUTE recommendation/hoeing (T3), Flat-bed planting (T4), Flat-bed planting & mulching (T5), Flat-bed planting & ridging (T6) and Flat-bed planting, ridging and mulching (T7) with 3 replications. The soil of experimental field was a sandy clay loam with uniform topography. The result showed that CIP Technique (T2) at par with Flat-bed planting, ridging and mulching (T7) were registered superior values of growth parameters viz.; plant height, number of compound leaves per plant and dry weight of haulm per plant (45.67 & 45.43 cm, 49.38 & 49.10 and 24.73 & 24.00 g; respectively), yield attributes viz.; number of tubers per plant and dry weight of tubers per plant (8.72 & 8.65 and 54.97 & 54.50 g; respectively) as well as tuber yield (299.23 & 282.44 qha-1) of potato over rest of the treatments.
