Abstract

                                Field experiments were conducted during 1997-98 at wood house farm, Udhagamandalam to study the effect of mepiquatchloride (MC) at different concentration from 50 to 250 gai ha compared along with pesticides, water spray and control. Plant samples were collected at 60 and 90 DAS and at harvest and analyzed for N, P and K contents. The results indicated that, foliar application of MC at 45 DAS recorded increased Total dry matter production (TDMP), nutrient content and uptake in the treatment of MC at 62.5 g ai ha-1 alone or in combination with endosulfan and mancozeb.

Key words : Mepiquatchloride, TDMP-Nutrient uptake, Potato.
