Influence of planting techniques, type of cuttings, PGRs and seasons on yield attributes in medicinal coleus (Plectranthus forskohlii Willd.)

Abstract

An experiment was conducted to study the influence of planting techniques, type of cuttings, PGRs and seasons on growth, tuber yield and quality in medicinal coleus (Plectranthus forskohlii Willd.) under northern dry zone of Karnataka. The experiment was conducted in split-split plot design with main plot: four treatments, sub plot 1: nine treatments and sub plot 2: two treatments. The interaction effect of planting techniques with the type of cuttings, PGRs and seasons (AXBXS) recorded that, A2B6S1 - Un rooted cuttings in ridge and furrow with the spray of CCC 750 ppm in the Kharif has obtained maximum dry tuberous yield. To obtain maximum tuber yield in medicinal coleus, planting of un rooted cuttings in ridge and furrow method of planting along with CCC-750 ppm (Sprayed at 60 & 90 DAT) in Kharif can be suggested to farmers to cultivate medicinal coleus crop under Northern dry zone of Karnataka.
