Studies were conducted over two years to evaluate the effect of seed soaking with biodigested slurry, zinc sulphate, Azospirillum, phosphobacteria and phytohormone in rice. The result of pot culture study showed that seed soaking in a combination of biodigested slurry, Azospirillum, phosphobacteria, zinc sulphate and phytohormone improved seedling characteristics such as plumule length, radicle length, biomass and seedling vigour. The N uptake increased by 11.8% at seedling stage (30th day). Soaking of seeds in a combination of nutrients enhanced the growth and yield attributes. Seed soaking in this combination of nutrients increased the grain yield by 8.8 % over unsoaked seeds. Uptake of N, P and K also enhanced by various soaking treatments. Uptake of zinc was not influenced by soaking treatments. The study indicated that seed soaking in a combination of organic, inorganic nutrient and biofertilizers is a good pre-sowing technique for rice.

Investigations were carried out during March to June 1991 to evaluate the effect of seed coating with organic, inorganic nutrients and biofertilizers on yield attributes and yield of soybean under three environments with different soil types viz., clay loam, sandy clay loam and sandy loam. Seed coating with bio‐digested slurry 50 per cent, superphosphate 2 per cent, Bradyrhizobium 2 per cent, and Phosphobacteria 2 per cent (w/w of seed) increased the number of filled pods and grain yield by 29.6 and 37.2 per cent, respectively over the uncoated. There was a significant increase in the test weight of grains due to seed coating with Phosphobacteria. Environment with clay loam soil was found to be highly responsive to seed coatings.
