Description Ph. D.
The trial was carried out during pre kharif and kharif seasons of 2009-10 and 2010-11 at the Agricultural Research Farm, Banaras Hindu University, Varanasi (India). The experiment consisting of 4 fertility levels control (F0), 50% RDF (F1), 100% RDF (F2) and 150% RDF (F3) and 2 methods of planting (flat bed and raised bed) along with 2 varieties (Pro-Agro 4212 and Sweet Corn Sugar-75) making 16 treatment combinations was laid out in a split plot design with 4 replications by keeping fertility levels in the main plot and planting methods and varieties in the sub plots. Baby corn (unfertilized maize ear) was harvested at 2–3 days of silk emergence stage and marketed as fresh corn (without husk). After harvesting of the baby corn the whole plant stover cut at ground level was spread over respective plots in small pieces. Sorghum was planted in the same lay out without any addition of fertilizer to study the residual effect of the first crop.
150% RDF (F3) fertility level was most effective to cause an improvement in the growth parameters, yield attributing characters, yield of baby corn and stover, nutrient contents (N, P, K, S and Zn) in baby corn and stover as well as quality parameters viz. protein, carbohydrate, sugar and starch content in baby corn and available nutrients (N, P, K, S and Zn) in the soil. 150% RDF (F3) fertility level was the most effective level for improving the net return of baby corn. Between planting methods, raised bed was effective in influencing growth parameters, yield attributing characters, baby corn and stover yields, N, P, K, S and Zn contents, protein content, economics (gross return, net return and B: C ratio) of baby corn and available nutrients (N, P, K, S and Zn) in the soil. Between varieties, Pro-Agro 4212 recorded correspondingly higher growth attributes, yield attributes, yield of baby corn and stover, nutrient contents and their removal besides improving the protein content, gross return, net return and B: C ratio of baby corn, while Sweet Corn Sugar-75 improved carbohydrate, sugar and starch content. 150% RDF (F3) level of fertility conjugated with raised bed and registered the highest values of plant height, dry matter production, N, P and protein content in baby corn and stover. Application of 150% RDF (F3) level of fertility with Pro-Agro 4212 registered the highest plant height, dry matter production, baby corn (with and without husk), stover yields, quality parameters viz. carbohydrate, sugar and starch content, gross and net return of baby corn. The residual effect of 150% RDF (F3) applied to baby corn showed significantly higher values of yield attributing characters, sorghum grain and stover yields, nutrients content (N, P, K, S and Zn) and their removal by sorghum and available nutrients (N, P, K, S and Zn) in the soil. The residual effect of 150% RDF (F3) applied to baby corn registered significantly higher gross and net return but remained at par with 100% RDF in case of benefit: cost ratio. Between planting methods, raised bed was effective in improving grain and stover yields of sorghum and available N in soil. On the bases of net return baby corn is recommended to be fertilized with 150% RDF viz.,225, 135, 135, 60, 15 kg N, P2O5, K2O, S, Zn ha-1 and its residues to be spread on the soil for maintenance of soil health and sustainable production of both the crops. Pro-Agro 4212 maize variety should be recommended with the application of 150% RDF (F3) to get maximum yield and net return. In baby corn- sorghum sequence baby corn should be fertilized with 225, 135, 135, 60, 15 kg N, P2O5, K2O, S, Zn ha-1 and its residues should be spread on the soil for sustainable production of both the crops as well as soil health.
