Abstract

Linseed is cultivated as paira crop in Odisha under residual moisture and minimal management practices which lead to lower productivity of the crop. A field experiment was conducted at Central Research Station, Odisha University of Agriculture and Technology, Bhubaneswar during rabi season of 2021. The experiment was laid out in a split-plot design with four replications comprising of five treatments viz., Soil Test Based Nitrogen Recommendation (STBNR) complete inorganic, Integrated Nutrient Management (INM) (50% organic* + 50% inorganic) *Organic= 1/3rd FYM+ 1/3rd poultry manure+ 1/3rd neem oil cake, Organic source (1/3rd FYM+ 1/3rd poultry manure+ 1/3rd neem oil cake), Soil Test Based Nitrogen Recommendation (STBNR)+ ZnSO4 @ 25 kg/ha and Integrated Nutrient Management (T2) + ZnSO4 @ 25 kg/ha in preceding rice crop along with two methods of crop establishment in linseed (Paira and conventional tillage) were allotted to the main plots and two nitrogen management practices in linseed (100% RDF and 50% N+ full PK) in the sub-plots. The soil was loamy sand, slightly acidic in reaction, medium in organic carbon, available P2O5 and K2O, and low in available nitrogen. The nitrogen management practices in rice influenced the yield attributes of linseed along with establishment methods and nitrogen management in linseed. The organic treatment in preceding rice crop influenced the most and paira cropping also proved to be superior as compared to conventional method.

Keywords

Nitrogen, Linseed, Integrated Nutrient Management, RDN

Conclusion

Among all the nitrogen management practices in the preceding rice crop, organic treatment and INM+ZnSO4 influenced the yield attributes more effectively indicating the residual effect of the previous treatment on the succeeding crop under paira cropping along with 100% RDN.
