Abstract
Sustainability of agricultural systems has become an important issue throughout the world. Basil has been used as a medicinal herb, so it has to be free from novice chemical substances. In this context, field experiment was carried out at ICAR - Indian Institute of Horticultural Research, Bengaluru, during kharif seasons of 2015 and 2016. Nine treatments with three replications were adopted in a randomized block design to find out the effect of different levels of N through FYM (100, 75 and 50% of the recommended N) along with and without bio-fertilizers, recommended dose of NPK (160:80:80 kg /ha) and recommended FYM (10 t/ha) + recommended NPK (160:80:80 kg /ha) on the growth, herb, nutrient uptake, oil yield and quality of French Basil (Ocimum basilicum L). The results from the experiment revealed that among the nine treatments, application of recommended dose of FYM (10 t/ha) along with recommended dose of NPK (160:80:80 kg /ha) recorded maximum fresh herb yield (62.56 and 56.08 t/ha) with average yield of 59.32 t/ha, maximum dry herbage yield (13.02 and 11.37 t/ha) with average yield of 12.19 t/ha and maximum oil yield (356.3 and 258.27 l/ha) with average yield of 307.28 l/ha and highest nitrogen uptake in the main crop (155.67 and 113.19 kg/ha) and ratoon (56.43 and 26.65 kg/ha) during 2015 and 2016 respectively. With respect to oil quality, the maximum methyl chavicol percentage (52.3%) in the main crop 2015 was recorded with application of recommended dose of FYM (10 t/ha) along with recommended dose of NPK (160:80:80 kg/ha) While, in the second season application of FYM (10 t/ha) +100% recommended N through FYM + bioferilizer recorded the highest percent of methyl chavicol (63.78%) in the main crop, as well as, in ratoon crop (59.39 and 59.67%) during 2015 and 2016, respectively.
