Abstract:
A field experiment was conducted on influence of wool waste on nutrient content and uptake of bottle gourd (Lagenaria siceraria) in western Rajasthan at research farm of Agricultural Research Station, SKRAU, Bikaner during Kharif, 2018. The experiment consisted ten treatments viz., T₁- Control, T₂- Recommended dose of fertilizer, T₃- wool waste@ 20 t ha^-1, T₄- RDF + wool waste @ 20 t ha^-1, T₅- RDF + wool waste @ 20 t ha^-1 + 1 per cent FeSO₄, T₆- RDF + wool waste @ 20 t ha^-1 + 1 per cent FeSO₄ + 0.5 per cent ZnSO₄, T₇- STCR recommendation fertilizer dose, T₈- STCR recommendation + wool waste @ 20 t ha^-1 + 1 per cent FeSO₄, T₉-STCR recommendation + wool waste @ 20 t ha^-1 + 1 per cent FeSO₄ and T₁₀ -STCR recommendation + wool waste @ 20 t ha^-1 + 1 per cent FeSO₄ + 0.5 per cent ZnSO₄. The experiment was laid out in randomized block design with three replications. Application of recommended dose of fertilizer with wool waste @ 20 t ha^-1 and foliar spray of 1 per cent FeSO₄ + 0.5 per cent ZnSO₄ had significant effect on bottle gourd yield. Significantly higher nitrogen, potassium, sulphur, zinc and iron in fruit and straw was recorded with the application of RDF + wool waste @ 20 t ha^-1 + 1 per cent FeSO₄ + 0.5 per cent ZnSO₄ as compared to control, whereas, phosphorus content was significantly influenced with RDF + wool waste @ 20 t ha^-1 + 1 per cent FeSO_4. Similarly, application of RDF + wool waste @ 20 t ha^-1 + 1 per cent FeSO₄ + 0.5 per cent ZnSO₄ had significant effect on nutrient uptake by fruit and straw of bottle gourd.
