Abstract :
The experiment was conducted during pre-kharif season of 2012 and 2013 at the Instructional Farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar on sandy loam soils under sub-tropical par-humid to tropical humid climate of terai region of West Bengal, to compare the performance of buckwheat (Fagopyrum esculentum Moench) under different sources of organic and inorganic nutrients. The field experiment was laid out in RBD (Randomized Block design) with fourteen treatments and three replications. Treatments comprised of T1 = Control, T2 = RDF (40:20:20), T3 = Vermicompost @ 2.5 t ha-1, T4 = Vermicompost @ 5 t ha-1, T5 = Mustard cake @ 2.5 t ha-1, T6= Mustard cake @5 t ha-1, T7 = Poultry manure @ 2.5 t ha-1, T8 = Poultry manure @ 5 t ha-1, T9 = F.Y.M @ 8 t ha-1, T10 = RDF +FYM @ 4 t ha-1, T11 = Vermicompost @ 2.5 t ha-1 + mustard cake @ 2.5 t ha-1, T12 = Vermicompost @ 2.5 t ha-1 + mustard cake @ 5 t ha-1, T13 = Vermicompost @ 2.5 t ha-1 + F.Y.M @ 4 t ha-1 and T14 = Vermicompost @ 2.5 t ha-1 + mustard cake @ 2.5 t ha-1 + poultry manure @ 2.5 t ha-1 + F.Y.M @ 4 t ha-1. Poled data revealed that seed yield of buck wheat were increased by 5.2 and 12.8 quintal ha-1 through combine application of vermicompost @ 2.5 t ha-1 + mustard cake @ 2.5 t ha-1 + poultry manure @ 2.5 t ha-1 + F.Y.M @ 4 t ha-1 over 100 % RDF and control. Combined application of vermicompost @ 2.5 t ha-1 + mustard cake @ 2.5 t ha-1 + poultry manure @ 2.5 t ha-1 + F.Y.M @ 4 t ha-1 (T14) recorded significantly higher percentage of starch (72.1 and 72.1) and protein (14.2 and 14.4) during 2012 and 2013, respectively which was followed by combined application of vermicompost @ 2.5 t ha-1 + mustard cake @ 5 t ha-1 (T12) and poultry manure @ 5 t ha-1 (T8). The highest benefit: cost (2.96) was noticed in T8 (Poultry manure @ 5 t ha-1) followed by T2 (2.83).
