ABSTRACT
A field experiment was conducted at Puliyanthoppu village in Krishnagiri District, Tamil Nadu during December 2019 – April 2020 to studythe effect of enriched poultry manure compost and liquid organic foliar nutrition on productivity, nutrient uptake, soil fertility, and microbial population in irrigated finger millet. The experiment was laid out in split- plot design with three replications. The results of the field experiment showed that, among the enriched compost, the application of enriched poultry manure compost applied @ 750 kg ha-1 significantly recorded higher ear heads m-2, grain and straw yields, higher nutrient uptake, soil fertility, and microbial population. The aforesaid parameters were least under plots received with enriched FYM compost @ 750 kg ha-1. In respect of liquid organic manures, foliar application of seaweed extract @ 0.3% on 20, 40, and 60 DAT significantlyrecorded higher ear heads m-2, grain and straw yields, and higher nutrient uptake, whereas soil fertility and microbial population were not significantly influenced by liquid organic manure application. The lowest values were registered in water spr ay.
