Abstract


A field experiment was conducted to enhance micro and secondary nutrient availability into calcareous soils and their
effect on mustard crop yield attributes. Treatment comprised with FYM level (control, @5 t ha-1 and @10 t ha-1) and five
treatment of sources of nutrient (control, 2.5 kg Zn + 1 kg B + 5 Kg Fe + 10 kg S ha-1, 5 kg Zn + 2 kg B + 10 kg Fe + 20 S
kg ha-1, 2.5 kg Zn + 1 kg B + 5 Kg Fe +10 kg S enriched FYM @ 500 kg ha-1 and 5 kg Zn + 2 kg B + 10 kg Fe + 20 kg S enriched
FYM @ 500 kg ha-1). Experiment results showed that application of FYM @ 10 t ha-1 along with 5 kg Zn + 2 kg B + 10 kg
Fe + 20 kg S enriched FYM @ 500 kg ha-1 significantly (p=0.05) improved yield attributes, seed yield (29.64 q ha-1), stover
yield (76.25q ha-1) and oil content (43.11%). Application of micronutrient enriched FYM improve the availability
of nutrient and their uptake to mustard results in higher productivity and quality of crop in calcareous soils. Highest
benefit cost ratio (3.22) was obtained under the treatment of M4 (2.5 kg Zn + 1 kg B + 5 kg Fe + 10 g S enriched FYM @
500 kg ha-1). Thus, micro and secondary nutrients concentration may be enhanced in soil through application of
enriched compost compared to alone use
