International Conference on Reimagining Rainfed Agro-ecosystems: Challenges & Opportunities
during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
(Arachis hypogea L.) was conducted at Oilseeds Research Station, Latur (Maharashtra) to study
the effect of INM on growth, yield and economics of groundnut during kharif season of 2020-21.
Methodology
The experiment was conducted in randomized block design with three replications on vertisols at
Oilseeds Research Station, Latur During kharif season of 2020-2021. Eight INM treatments were
applied to the crop viz., T1- RDF(control) , T2- RDF+FYM @ 5 t/ha., T3- RDF+ Vermicompost
@ 2.5 T/ha., T4- RDF+Poultry manure @5 t/ha., T5- RDF+Elemental Sulphur @ 20 kg/ha., T6-
RDFR+ Znso4 @ 20 kg/ha., T7- Feso4 @ 20 kg/ha and T8- RDF+Gypsum @ 500 kg/ha. All the
nutrients were applied at the time of sowing. The data were analyzed statistically with standard
ANOVA method.
Results
Pod yield, Gross monetary returns (GMR), Net monetary returns (NMR) and B: C ratio of
groundnut varied significantly due to various nutrient management treatments. Treatment T3 i. e.
application of RDF+Vermicompost @ 2.5 t/ha recorded significantly highest pod yield (2080
kg/ha.) which was found at par with T2 (RDF+FYM @ 5 t/ha.) and T8 (100% RDF+Gypsum @
500 kg/ha.) The highest GMR (99840 Rs/ha.) was also recorded with application of
RDF+Vermicompost @ 2.5 t/ha which was found at par with the application of RDF+ FYM
@5t/ha and RDF+ Gypsum @500 kg/ha. The highest NMR (52025 Rs/ha.) was recorded with
the application of RDF+Vermicompost @ 2.5 t/ha which was found at par with treatment T8
(RDF+ Gypsum @500 kg/ha.) The highest B: C ratio was obtained with the application of RDF+
Gypsum @500 kg/ha followed by treatment T7 (RDF+ Feso4 @ b20 kg/ha.)
Conclusion
On the basis of present investigations, it is concluded that application of RDF+ Vermicompost @
2.5 t/ha recorded significantly highest pod yield (2080Kg/ha), highest GMR (99840 Rs/ha),
NMR (52025 Rs/ha) and B:C ratio followed by application ofRDF + FYM @ 5t/ha and
application of RDF+ Gypsum @ 500 kg/ha.
