Strategies for Increasing Production of Rapeseed/Mustard

  • Area expansion: Limited scope
  • High yielding varieties: Already available and limited scope for further improvement
  • GM Varieties: No clear policy of the Government till now
  • Package of practices and nutrient management: Scope in view of the deficiency of mineral nutrients due to intensive agriculture

slide6

Our Approach for Increasing Production of Rapeseed/Mustard

Synergize use of high yielding varieties with balanced and split application of N&S at appropriate phenological stages along with phosphorus and potassium

OBJECTIVE

  To Increase the Yield and Production of Rapeseed/Mustard through Improved Nutrient Management Protocol at Farmers’ Fields.

Experimental Design

  • Three states namely Haryana, Rajasthan and Utter Pradesh out of the major rapeseed/mustard growing states were selected. In Delhi, we had used experimental plots at Jamia Hamdard, New Delhi – 110062.
  • Farmers in these states were identified who agreed to participate in the programme. Farmers’ field size varied from 1Acre to 1 Hectare.
  • Soil samples were collected for the analysis of available N &S before sowing.
  • In each farmers’ field one control plot was maintained.
  • In control plot the rapeseed/mustard crop was cultivated using conventional nutrient management package.
  • In rest of the field the crop was cultivated using improved nutrient management protocol.
  • Yield components and productivity of the crop were analyzed after harvesting the crop from both the plots and the data were compared.

Sulphur Deficiency in Soil

The major factors responsible for S deficiency in the soil are:

 1.  Increasing depletion of S through higher yield and cropping

intensity.

 2.  Large scale shift towards S free product in the fertilizer use

pattern.

 3.  Losses of S through leaching and soil erosion.

 4.  Microbial transformations in the soil.

Discussion

  • Increase in productivity of rapeseed/mustard reported is a result of the following contributing factors:
  • -Impact of using seeds of improved varieties (Pusa Gold and Pusa Jai Kisan)
  • -Impact of following improved nutrient management package incorporating N,P,K & S and their application in split dosage at appropriate phenological stages of crop.
  • Increase in no. of pods per plant and weight of 1000 seeds in pods is attributed to increased photosynthesis as a result of adopting improved nutrient management package.
  • 3. Magnitude of increase in yield in response to the improved nutrient management package depends on the severity of sulphur deficiency

Conclusion

The yield of rapeseed/mustard can be increased with the application of sulphur and nitrogen in balanced and split doses at appropriate phenological stages along with phosphorus and potassium with very high benefit:cost ratio.
