Abstract

The modern cultivated cauliflower (Brassica oleracea L. var. botrytis) is one of the most important, vegetable and nutritious vegetable for the world. Increasing need for enhanced crop productivity due to ever increasing population necessitates adequate amount of plant nutrition. Integrated Nutrient Management involves judicious use of organic, inorganic and microbial sources in such a way that it sustains optimum yield, improves and maintains the soil physical, chemical and biological properties, which can bring about equilibrium between degenerative and restorative activates in the soil environment. A field experiment was carried out At the Department of Horticulture, Baba Farid Group of Institute of Management and Technology, Dehradun (U.K.)-248007 (India), during October 2020 to February 2021 to assess the growth and yield characteristics of cauliflower (Brassica olearaceaceae L.) botrytis cv. Snow crown. There were 8 treatments comparing control T1, T2 (recommended dose of NPK (150:100:80 kg/ha), T3 (half dose of NPK/ha+FYM@15 t/ha), T4, (half dose of NPK/ ha + Vermicompost @ 2.5 t/ha + FYM @ 15 t/ha), T5 (Half dose NPK/ha + Vermicompost @ 2.5 t/ha + Azospirillium @ 5 kg/ha), T6 (Half dose NPK/ha + VAM @ 5 kg/ha), T7 (half dose NPK/ha + FYM @15 tons/ha + Azosprilliun @5 kg/ha), T8 (half dose NPK/ha + Azospirillium @ 5 kg/ha). result cm) plant spread (44.30 cm), curd diameter (19.96 cm), curd weight per plant (1002.63 g), curd yield per plot (9.31 kg) and curd weight per hectare (31.04 t/ha) were observed at half the dose. NPK/ha + Vermicompost @ 2.5 t/ha + Azospirillium @ 5 kg revealed that the highest plant height (59.42 cm), number of leaves (16.28), leaf length (49.02 /ha (T5). half dose of NPK/ha + Vermicompost @ 2.5 t/ha + Azospirillium @ 5 kg/ha to increase growth and yield of cauliflower.

Conclusion

Based on the results, of this study it can be realized that among the treatments on cauliflower application half dose of NPK/ha + Vermicompost @ 2.5 tonnes/ha + Azospirillium @ 5 kg/ha (T5) was found to be best for growth and yield of the cauliflower. Application half dose of NPK/ha + Vermicompost @ 2.5 tonnes/ha + Azospirillium @ 5 kg/ha (T5) was found effective in improving plant height, number of leaves per plant, spread of plant, curd diameter, curd weight, yield per plot and yield per hectare. The application half dose of NPK/ha + Vermicompost @ 2.5 tonnes/ha + Azospirillium @ 5 kg/ha (T5) for growth and yield of cauliflower. It was found to be most remunerative for farmers.From this study it can be recommend that the application of INM at half dose of NPK/ha + Vermicompost @ 2.5 tonnes/ha + Azospirillium @ 5 kg/ha can be applied to obtain maximum yield of Cauliflower variety Snow crown.
