Abstract

The research programme was carried out during early summer seasons of 2012 and 2013 at the experimental farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar to study the direct and left over effect of organics on Buckwheat (Fagopyrum esculentum Moench) – fodder Rice bean (Vigna umbellata) cropping system. The trial was carried out in Randomized block design with 14 treatments and replicated thrice. Results demonstrate that combined application of vermicompost, poultry manures, mustard cake and farmyard manure improved seed yield of buck wheat by 0.51 and 0.53 t ha-1 over 100 % RDF in 2012 and 2013, respectively. Among the sole application of organic manures, application of poultry manure at 5 t ha-1 proved its superiority in terms of stem and seed yield of buck wheat. Collective application of vermicompost at 2.5 t ha-1 + mustard Cake at 2.5 t ha-1 + poultry manure at 2.5 t ha-1 + Farmyard manure at 4 t ha-1 to the preceding buckwheat crop produced 18.67 and 17.20% more fodder yield of ricebean than 100 % chemically treated plot during both the years. Application of vermicompost at 2.5 t ha-1 + mustard Cake at 2.5 t ha-1 + poultry manure at 2.5 t ha-1 + Farmyard manure at 4 t ha-1 also leave highest amount of available N, P and K in the soil. Economic analysis revelaed that treatment producing highest yield of buck wheat and ricebean fetched lower B: C ratio (0.63 and 0.74 during 2012 and 2013, respectively) as compared to other treatemnts.

Highlights

Organic manures have traditionally been the important input as sources of plant nourishment
The highest stem (2.83 t ha-1 during 2012 and 2.97 t ha-1 during 2013) and seed yield (1.65 t ha-1 during 2012 and 1.77 t ha-1 during 2013) was observed in integrated use of vermicompost at 2.5 t ha-1 + mustard cake at 2.5 t ha-1 + poultry manure at 2.5 t ha-1 + F.Y.M at 4 t ha-1 (T14) might be due to more leaf area, dry matter accumulation, crop growth and yield attributes followed by joint application of vermicompost at 2.5 t ha-1 + mustard cake at 5 t ha-1 (T12) that was statistically equal with sole appliance of poultry manure at 5 t ha-1 (T8) during both the years of experimentation
Similar significant increases on plant height (115.6 and 117.8 cm), number of branches plant-1 (5.2 and 5.3) and number of leaves plant-1 (77.7 and 78.3) were observed in T14 followed by joint use of vermicompost at 2.5 t ha-1 + mustard cake at 5 t ha-1 (T12) which was statistically equal with the sole application of poultry manure at 5 t ha-1 (T8) during both the years of experimentation

Summary

Introduction

Organic manures have traditionally been the important input as sources of plant nourishment. The highest stem (2.83 t ha-1 during 2012 and 2.97 t ha-1 during 2013) and seed yield (1.65 t ha-1 during 2012 and 1.77 t ha-1 during 2013) was observed in integrated use of vermicompost at 2.5 t ha-1 + mustard cake at 2.5 t ha-1 + poultry manure at 2.5 t ha-1 + F.Y.M at 4 t ha-1 (T14) might be due to more leaf area, dry matter accumulation, crop growth and yield attributes followed by joint application of vermicompost at 2.5 t ha-1 + mustard cake at 5 t ha-1 (T12) that was statistically equal with sole appliance of poultry manure at 5 t ha-1 (T8) during both the years of experimentation.
