Abstract:
Demonstration was conducted during rabi (December, 2020–April, 2021) on the horticulture farm at Krishi Vigyan Kendra, Sardarkrushinagar Dantiwada Agricultural University, Khedbrahma, Sabarkantha, Gujarat, India to study the impact of improved varieties with integrated crop management (ICM) in onion and scientific temperament of farmers of North Gujarat part. The demonstration was conducted in four plots (replications) consists of five varieties (treatments). About 55 days old seedlings of onion were transplanted in flat beds at a spacing of 15 x 10 cm. Four improved varieties of rabi onion are compared with local variety. The varieties (treatments) are symbolized as T₁- Agrifound Light Red, T₂ - NHRDF Red2, T₃ - NHRDF Red3, T₄ - NHRDF Red 4 and T₅ – Local of Sabarkantha region of Gujarat (Farmer’s seed). The parameter wise data (yield parameter like bulb yield, quality parameter like bolting percent and visual appearance of bulb) of four plots (replications) and five varieties (treatments) was recorded to assess the impact of KVK interventions on onion yield and economics and analyzed in randomized block design (RBD). All these four improved varieties of rabi onion under demonstration had significant impact on bulb yield, bulb quality, bolting per cent and economic as compared to the local variety. Significantly higher bulb yield and net return, superior bulb quality and lower bolting per cent was recorded in improved onion varieties as compared to the local.
