Abstract:
A field experiment was carried out during Rabi 2021-22 at the Research field of Agronomy, Central Agricultural University, Imphal (Manipur) to assess the effect of chemical fertilizer, poultry manure and their integration on yield of fodder oat and to study the economic feasibility of the different treatments. The experiment was laid out in a randomized block design (RBD) with three replication consisted of seven treatments. The maximum green fodder yield (475.50 q ha^-1), dry matter content (19.6%), dry matter yield (91.31 q ha-¹), per day productivity of green fodder (5.75 q ha^-1 day^-1) and per day productivity of dry fodder (1.10 q ha^-1 day^-1) were recorded with the application of 75% RDF + 2 t poultry manure ha^-1 while maximum days taken to 50% flowering was recorded in the treatment which received only 1 t PM ha^-1. From economic point of view, the highest net monetary returns (60562 Rs ha^-1) with B: C ratio (2.75) were also recorded with the application of 75% RDF (60:40 NP) kg ha^-1 along with 2 t poultry manure ha^-1. Integrated nutrient management involving 75% RDF + 2 t PM ha^-1 was found to be the most effective in terms of fodder yield production and economics for fodder oat cultivation as compares to the sole application of poultry manures or chemical fertilizers.
