The experiment was conducted during the year 2014- 15 in Dungariya village, Barghat block, Seoni district, Madhya Pradesh. The study was planned under RBD, with four replications and six treatments viz., Micronutrients (T1), Zinc (T2), Boron (T3), Plant growth regulator (Chlormequat chloride 50% SL) (T4), Humic acid (T5) and Control i.e. water spray (T6). The results revelled that the mean dry weight (g) of 100 cells of lac insect varied from 3.82g to 5.18g. The mean dry weight of 100 lac cells was highest in T4 (5.18) followed by T2 (5.14g), T3 (5.02g), T1 (4.59g), T5 (3.86) and T6 (3.82g). The mean dry weight (g) of raw lac per 30 cm stick varied from 07.53 to 21.57g and it was highest in T4 (21.57), followed by T2 (16.88), T3 (15.14), T1 (13.00), T5 (10.41) and T6 (07.53). The mean yield of raw lac (kg) per plant obtained after harvesting of lac crop was 4.01, 3.41, 3.24, 2.52, 2.32 and 2.03 respectively among the treatments viz., T4, T2, T3, T1, T5 and T6.
