The experiment was laid out in randomized block design. The different organic manures included were farmyard manure, poultry manure and neem cake. The experiment was carried out using the cultivar Maran. The salient findings are abstracted below.
Plant height was found to be favourably influenced by the treatments except neem cake. Number of tillers per plant and number of leaves per tiller were not influenced by the different treatments.
Dry matter accumulation in the leaves and rhizomes was comparatively higher in the treatments poultry manure alone and farmyard manure alone. Root dry weight was the maximum in the treatments, Azospirillum + 75 per cent N. The treatment farmyard manure was significantly superior to others as far as total dry matter production was concerned.
Yield of green ginger and dry ginger and dry ginger recovery were found to be higher in the treatments farmyard manure and Azospirillum, though not significant. Oleoresin content was unaffected by the different treatments. Percentage of essential oil was significantly higher in the treatments. Azospirillum + 75 per cent N and farmyard manure.
Uptake of N and P was higher in the treatments poultry manure alone, Azospirillum + 50 per cent N and farmyard manure alone.
Incorporation of farmyard manure in the soil resulted in the enhancement in organic carbon content of soil. Plots receiving inorganic form of N contained more available N in soil after the experiment.
Neem cake was found to be effective in reducing the incidence of soft rot disease.
The most profitable among the different treatments was farmyard manure alone.
