Performance of Potato Variety Rolpa Local (Solanum tuberosum L.) under Different Mulching Conditions and Zinc Levels at Rolpa, Nepal

Use of the right mulching techniques is a crucial first step in replacing issues with irrigation and weed infestation potato production. To assess performance potatoes at two doses zinc under different conditions, field experiment was laid out two-factorial, randomized complete block design (RCBD) comprising eight treatments three replications each. The variety used Rolpa local. factor consisted materials: plant residue (M1), black plastic (M2), silver on (M3), control plot (M0), whereas second compromised levels (0 kg/ha 4 kg/ha). Both mulches were found to have significant influence germination rate during research; however, all other observations for growth yield parameters, such as height, tuber number, weight, per plant, significantly superior plastic. highest percentage observed mulch (94.67 %). However, parameters be condition, height (87.28 cm), leaf count (145.70), number tubers (22.16), total 21.83 t/ha. Similarly, yield-attributing characters among levels, 17.70 t/ha zinc. Silver level resulted benefit-cost (B:C) ratios 3.18 2.23, respectively. results showed that using improved both vegetative yield, favorable B:C resulting higher profitability. Thus, maximize profit, it would advantageous utilize
