ABSTRACT

A field experiment entitled ‟Organic phosphorus management in green gram” was conducted at dryland Farm, S.V. Agricultural College, Tirupati campus of Acharya N.G. Ranga Agricultural University, Andhra Pradesh, India during rabi season, 2023-24. The experiment was laid out in split plot design and replicated thrice. The results of investigation revealed that among the different sources of organic manures recorded significantly higher values of plant height, leaf area index, dry matter production, seed yield and haulm yield of green gram were observed with 100 % RDP through poultry manure (M3) compared to other manures tried. Foliar application of seaweed extract @ 1 % (S4) resulted in higher values of plant height, leaf area index, dry matter production, seed yield and haulm yield of green gram over the other organic foliar sprays tried. The interaction effect found to be non- significant for all the parameters.

KEYWORDS: Greengram, Poultry manure, Seaweed extract.
