Effect of Organic Manure and Biofertilizers on Yield and Yield Attributes Characteristic of Cabbage (Brassica oleracea L. Var. Capitata) cv. Golden Acre

The present investigation was carried out at Assam Agricultural University, Jorhat in Horticulture farm during 2009 and 2010, to study the performance of cabbage as influenced by organic manures and biofertilizers. Combined use of organic manures and biofertilizers (PSB + AZB) registered head yield at par to control (RDF). The result revealed that growth and yield attributing characters were significantly influenced by the application of different nutrient sources. The highest plant height (19.47 cm and 25.22 cm), number of leaves at different stage 20 & 40 DAP (9.9 and 12.38) and plant spread (52.15 cm) were reported under T₁₀. The maximum number of wrapper leaves (40.83), non-wrapper leaves (11.50), stalk length (7.28 cm), overall plant weight (0.790 kg), head diameter (13.52 cm), head weight (0.54 kg), and yield/ha (23.35 t/ha) were recorded under treatment T₁₀ which was at par with T₄. Other parameters viz., weight of non-wrapper leaves (164.16g), root length (33.75 cm), maximum root fresh (42.01g) and dry weight (8.7g) and compactness of head (28.00) were recorded highest under the treatment T₄. However, highest dry matter content (6.87%) was recorded under T₆. The highest head to root ratio were recorded under T₁₀ (14.36) which was at par with T₄ and T₈. All the growth parameters were significantly poor under biofertilizers (PSB + AZB) inoculated treatment. However, highest harvest index was recorded under T₁₀ (55.05%) which was at par with T₄, T₇, T₈ and T₃.
