Abstract:
A field experiment was conducted to study the influence of different nutrient management schedules on various physiological attributes of organic cabbage during 2017-18 and 2018-19 at Uttar Banga Krishi Viswavidyalaya (UBKV), Pundibari, Cooch Behar, West Bengal, India by combining 8 treatments in randomized block design with 3 replications. The results revealed that the treatment comprising of combined use of enriched farmyard manure (7t ha-1), enriched poultry manure (2t ha-1) and enriched vermicompost (2t ha-1) as basal dose along with top dressing of enriched farmyard manure (2t ha-1), enriched vermicompost (0.25t ha-1) and enriched poultry manure (0.25t ha-1) at 30 and 60 DAT (T8) recorded the maximum leaf area index of cabbage (2.70). The treatment comprising of sole enriched vermicompost (5t ha-1) as basal along with enriched vermicompost (1t ha-1) as top dressing at 30 and 60 DAT (T3) recorded maximum dry matter accumulation (11.43%). Again, the treatment comprising of sole use of enriched poultry manure (5t ha-1) as basal along with enriched poultry manure (1t ha-1) as top dressing at 30 and 60 DAT (T4) recorded maximum chlorophyll content (73.03 SPAD value) as well as highest head weight (1.64 kg), head yield per hectare (42.76 t). The maximum harvest index (71.30%) was also recorded by this treatment. The study suggested that application of Azophos biofertiliser enriched poultry manure (5t ha-1) as basal along with 2 times top dressing of biofertiliser enriched poultry manure (1t ha-1) exerted maximum influence on different physiological attributes of organic cabbage.
