Abstract
The present investigation entitled “Synergistic Effects of Organic and Inorganic Nutrient Sources on Nutrient Uptake and Productivity of Barley (Hordeum vulgare L.)” was carried out at the Research Farm, Department of Agronomy, Vivekananda Global University, Jaipur, Rajasthan. The experiment was laid out in Randomized block design with eight treatments replicated thrice. The experiment was comprised with eight treatment viz., T1-control, T2- RDF 100%, T3- Vermicompost 10 t/ha, T4- FYM 20 t/ha, T5- RDF 75% + FYM 5 t/ha, T6- RDF 50% + FYM 10 t/ha, T7- RDF 50% + Vermicompost 5 t/ha and T8- RDF 75% + Vermicompost 2.5 t/ha. The treatment with application of T8- RDF 75% + Vermicompost 2.5 t/ha was recorded significantly higher plant height (107.63 cm), number of tillers/running row meter (66.32), plant dry weight (22.31 g/plant) and crop growth rate (25.73 g/m2/day). Treatment RDF 75% + Vermicompost 2.5 t/ha (T8) significantly improved the yield attributes viz., number of effective tillers per plant (278.85) and number of grain per spike (52.27). However, T7- RDF 50% + Vermicompost 5 t/ha, T6- RDF 50% + FYM 10 t/ha and T5- RDF 75% + FYM 5 t/ha was found to be statistically at par with T8- RDF 75% + Vermicompost 2.5 t/ha. For test weight difference between treatments was observed non-significant.
The treatment T8- RDF 75% + Vermicompost 2.5 t/ha registered significantly higher values of N, P and K uptake in seed as well as grain. The maximum cost of cultivation (INR 40755.10 /ha), maximum gross return (INR 1,30,130.17/ha), maximum gross return (INR 1,30,130.17/ha), maximum net return (INR 89,375.07/ha) and maximum benefit cost ratio (2.19) was observed in T8- RDF 75% + Vermicompost 2.5 t/ha. Whereas the minimum cost of cultivation ((INR 38399.10 /ha), minimum net return ((INR 68,870.27/ha)) and minimum benefit cost ration (1.79) was observed in treatment T1-control.
