Abstract:
The present research entitled “Studies on effect of organic and inorganic fertilizers on growth, yield attributes of cabbage (Brassica oleracea L. var. capitata)” was carried out at the research block of the Medicinal and Aromatic Plant Research Station, Rajendranagar, during Rabi-2020. The experiment was laid in factorial randomized block design with three replications.
The experiment was executed with objectives to study the effect of organic fertilizers on growth and yield of cabbage, to study the effect of inorganic fertilizers on growth and yield of cabbage, to study the effect of organic and inorganic fertilizers on growth and yield of cabbage.
Among the organic fertilizers [vermicompost (5 t/ha), Azotobacter (4 kg/ha), Azospirillum (4 kg/ha), Azotobacter (4 kg/ha) + Azospirillum (4 kg/ha)] in cabbage. Azotobacter (4 kg/ha) +Azospirillum (4 kg/ha) significantly recorded the maximum polar diameter of cabbage (15.16 cm), equatorial diameter of cabbage (11.77 cm), head yield per plot (19.86 kg) and head yield per hectare (331.12 q).
Among the different levels of inorganic fertilizers [100% RDF, 75% RDF, 50% RDF] in cabbage. 100% RDF through inorganic fertilizers significantly recorded the maximum polar diameter of cabbage (15.59 cm), equatorial diameter of cabbage (12.12 cm), head yield per plot (19.15 kg), head yield per hectare (319.21q). 100% RDF through inorganic nutrients treated plant also took minimum number of days to first leaf folding (30.64), days to 50% head maturity (80.09).
The interaction between organic fertilizers and inorganic fertilizers has shown significant results, the maximum polar diameter of cabbage (16.12 cm), equatorial diameter of cabbage (12.37 cm), head yield per plot (22.36 kg), head yield per hectare (372.77 q) was noticed in Azotobacter + Azospirillum in combination with 100% RDF. Highest benefit cost ratio (3.72) was recorded at (T8) - Azotobacter + Azospirillum in combination with 75% RDF which was followed by (T4) - Azotobacter + Azospirillum in combination with 100% RDF (3.67) and lowest benefit cost ratio was recorded in (T9) - vermicompost (5 t/ha) in combination with 50% RDF through inorganic fertilizers.
From the above results, it can be concluded that highest plant growth and yield in cabbage recorded in application of Azotobacter (4 kg/ha) + Azospirillum (4 kg/ha) with 100% RDF through inorganic fertilizers followed by application of Azotobacter (4 kg/ha) + Azospirillum (4 kg/ha) with 75% RDF through inorganic fertilizers and lowest plant growth, yield is recorded in application vermicompost (5 t/ha) with 50% RDF through inorganic fertilizers. Whereas highest benefit cost ratio is recorded in plots with application of Azotobacter (4 kg/ha) + Azospirillum (4 kg/ha) with 75% RDF through inorganic fertilizers.
