Abstract

Food and nutrition scientist show more interest towards millets and its health effects on combating lifestyle diseases and now millets are regaining its importance on achieving nutrition security. Proso millet is a true millet of history that can grow well in many agro-climatic conditions. Though the chemical fertilizer increases the plant growth and vigour, hence meets the food security of the world but chemically produced plant will accumulate in the human body as toxic chemicals, which are very dangerous. Various researchers have investigated the possibility of augmenting vermicomposts with additional nutrient-rich organics (enriched vermicompost) as a remedy to the poor nutrient content of organic manures. The liquid organic solutions are the source of macronutrients, important micro nutrients, vital amino acids, growth stimulating factors like IAA, gibberellic acid and favourable microorganisms. Hence, the present study was carried out to study the effect of enriched vermicompost and organic foliar spray on growth and yield of prosomillet at Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu. The experiment was laid out in Randomized Block Design (RBD) with thirteen treatments and three replications. Treatments consists of T1: 100% Vermicompost, T2: 100% Enriched vermicompost, T3: 100% Enriched vermicompost + 3% Humic Acid, T4: 75% Enriched vermicompost + 3% Humic Acid, T5: 100% Enriched vermicompost + 3% Sea weed extract, T6: 75% Enriched vermicompost + 3% Sea weed extract, T7: 100% Enriched vermicompost + 3% PPFM, T8: 75% Enriched vermicompost + 3% PPFM, T9: 100% Enriched vermicompost + 3% Panchagavya, T10: 75% Enriched vermicompost + 3% Panchagavya, T11: 100% Enriched vermicompost + 3% Vermiwash, T12: 75% Enriched vermicompost + 3% Vermiwash, T13: Control (no manure and foliar spray). The study revealed that among the different doses of enriched vermicompost and organic foliar nutrition, 100% enriched vermicompost + 3% sea weed extract recorded higher growth parameters viz., plant height, LAI, number of tillers and yield attributes, grain yield (2172 kg/ha) and straw yield (4085 kg/ha) of prosomillet and it was comparable with 75% enriched vermicompost + 3% sea weed extract. The lowest grain (960 kg/ha) and straw yield (2100 kg/ha) were recorded in control without any vermicompost and foliar spray of nutrients which signifies the importance of application of enriched vermicompost and foliar nutrition in prosomillet.

Conclusion

It can be concluded from the result that the enriched vermicompost and organic foliar nutrition were significantly influenced the growth and yield of prosomillet and the treatment T5 (100% Enriched vermicompost + sea weed extract) was found the best treatment among all the treatments and it gave the maximum growth and yield, whereas it was comparable with T6 (75% Enriched vermicompost + Sea weed extract). On the basis of the result obtained after completion of present investigation it was concluded that application of 100% enriched vermiompost on equal N basis along with foliar spray of 3% seaweed extract increases growth parameters and yield attributes, grain yield of prosomillet.
