The effect <strong>of</strong> various organic sources on tomato yield was found to be significant. The<br />

treatment T10 i.e. RDF + FYM 5 t /ha recorded the highest tomato yield (33.8 t/ha) which was<br />

found significantly superior over rest <strong>of</strong> the treatments. The lowest tomato yieldwas recorded in<br />

T11 (20.3 t/ha) i.e. control. The highest GMR was obtained with the application <strong>of</strong> RDF + FYM 5<br />

t/ha (T10) (₹ 257920/ha) which was significantly superior over rest <strong>of</strong> the treatments. Similar<br />

trend was observed in case <strong>of</strong> NMR. Whereas, application <strong>of</strong> RDF + FYM 5 t /ha recorded<br />

highest B:C ratio (3.45) followed by treatment T9 (2.74) i.e. RDF + FYM 5 t /ha + Phosphorich<br />

@ 157 kg/ha + Neem cake @ 400 kg /ha. Among the organic treatments, application <strong>of</strong> RDN<br />

100% through Vermicompost (T2) recorded highest tomato yield (26.1t/ha), highest GMR<br />

(Rs.209626 /ha) and highest NMR (Rs. 148440/ ha) over rest <strong>of</strong> the treatments. Similar results<br />

were reported by (Shankar et al. 2012) that organically grown tomato has found to be<br />

significantly influenced the nutrient content compared to tomato grown through conventional <strong>of</strong><br />

fertilizer application<br />

Conclusion<br />

The results revealed that the application <strong>of</strong> RDF + 5 t FYM/ha produced significantly higher<br />

tomato yield (33.8 t/ha), highest GMR (₹257920 /ha) and highest NMR (₹183200/ha). However,<br />

among organic treatments application <strong>of</strong> RDN 100 % through vermicompost (T2) recorded<br />

highest tomato yield (26.1 t/ha), highest GMR (₹ 209626 /ha) and highest NMR (₹145440/ha).<br />
