Effect on Vegetative Growth and Economic Feasibility of Potato (Solanum tuberosum L.) cv. Kufri Bahar through Foliar Spray of Bulk Chlorocholine Chloride (CCC) & Nano CCC

A field experiment consisting 12 treatments having 3 replications was carried out from November (2020-21 & 2021-22) at Rajasthan College of Agriculture, Udaipur (Rajasthan) to asses’ economic feasibility of chlorocholine chloride (CCC) and Nano CCC on potato. CCC-CS NFs (0.04, 0.08, 0.12, 0.16 and 0.20% w/v), CCC (0.04, 0.08, 0.16, 0.20% w/v), bulk chitosan (BCH 0.01% w/v) and control (water) were applied through foliar application at tuber initiation at 25th day and tuber bulking at 45thdays. Pooled data of two years showed that CCC-CS NFs (0.20%) got maximum net return (Rs. 267005.90) and maximum leaves/plant followed by 0.16% CCC-CS NFs (386 leaves) as comparative to rest of treatments. Non-significant difference in leaf area was recorded in all concentration of CCC-CS NFs, CCC, BCH and control.
