Abstract
ABSTRACT
The present investigations entitled “Studies on the standardization of cultivation
practices of Andrographis paniculata Nees under mid hill conditions of Himachal Pradesh”
were carried out in the experimental field and laboratory of the Department of Forest
Products, Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.)
during the year 2008-09. The effect of nursery practices, spacings, fertilizers and harvesting
stages was studied on growth and yield parameters of Andrographis paniculata and further
cost of cultivation was also calculated. The results revealed that application of different soil
media and field conditions had significant effects on growth and development of A.
paniculata. Soil + vermicompost (1:1) medium in glasshouse conditions was found to give
best results for seed germination and growth parameters. Line spacing of 15x15 cm with
grass mulch gave best result for seed germination and seedling vigour. Among spacings,
fertilizers and harvesting stages, 15x15 cm with application of NPK @ 75:75:50 kg/ha at post
full blooming stage registered the maximum fresh and dry aerial and underground biomass
followed by the application of PSB, VAM and Azotobactor @ 10 kg/ha in A. paniculata.
Maximum benefit: cost ratio (3.79:1) was obtained at 15x15 cm spacing with the application
of NPK @ 75:75:50 kg/ha at post full blooming stage. Among different organic fertilizers,
benefit: cost ratio was found maximum with the application of PSB (2.89:1) followed by
VAM (2.84:1) and Azotobactor (2.59:1) @ 10 kg/ha application, FYM (1.90:1) and
vermicompost (0.73:1) @ 20t/ha at 15x15 cm spacing.
