Description The present investigation was carried out at the MA & UUP Research Area of
CCS Haryana Agricultural University during the year 2005. The main objective was to
find out the optimum plant spacing and best harvesting time Kalmegh crop. Four
harvesting time (120, 135, 150 DAP and at seed maturity) and equal number of plant
spacing (30 x 15, 30 x 10, 20 x 15 and 20 x 10 cm) were taken split plant design with
three replications. The growth parameters i.e. plant height, leaf area index, stem
diameter, number of branches per plant, leaf : stem ratio, leaf yield and dry matter per
plant were statistically maximum at 135 days after planting. The green and dry herbage
yields were (148.83 and 54.53 q/ha) with net returns (Rs. 59282/ha) and B :C ratio
(2.32) at this stage. Seed yield attributes i.e. capsule length, capsule width, number of
capsules per plant, seed per capsule, seed yield per plant and seed yield (kg/ha)
increased up to seed maturity. Among plant spacing all the growth parameters and seed
yield attributing parameters except leaf area index were maximum in 30 x 15 cm plant
spacing but the fresh and dry herbage yield (121.64 and 46.53 q/ha) and seed yield
(20.37 kg/ha) were maximum in 20 x 10 cm plant spacing. Andrographolide content
and its yield were maximum at 135 days after planting. Iron content was maximum at
120 days after planting, but its uptake was maximum at 135 days after planting.
Harvesting at 135 days after planting and plant spacing of 20 x 10 cm was resulted in
maximum net returns and B : C ratio.
