Energy Inputs and Yield Relationship in Greenhouse Okra Production by Bio-priming

Production of chemical fertilizers is associated with consumption of huge energy. In the present study, an attempt was made to assess the energy consumption in bio-priming mediated okra production under greenhouse conditions. Results showed that among all the treatments, seed priming with Trichoderma harzianum (NBRI 1055) along with 90% RDF was not only helpful in reducing fertilizer dose by 10%, but at the same time produced almost similar yield as compared to with 100% RDF. Bio-priming in different combination with chemical fertilizers had a positive impact on the chemical composition of okra. Bioprimed treatments saved 970 to 1670 KJ energy in producing unit produce as compared with 100% RDF. This proved that bio-priming is cost-effective, user, and eco-friendly technique solving numerous problems in agriculture. This technique requires the prerequisite of incorporating organic matter in soil and seen as complementary to inorganic fertilizer source, not as their replacement.
