Abstract:
An Agronomic investigation “Effect of mechanization on productivity, growth, yield and economics of soybean” (Glycine max (L.) Merill)” was carried out at Experimental farm, of AICRP for dryland Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during kharif 2019. The experiment was conducted which consisted of three treatments of mechanization practices as main plots and three treatments of moisture conservation as sub plots constituting six treatment combinations which were replicated thrice in split plot design. The three mechanization practices of full mechanization (M₁), partial mechanization (M₂) and no mechanization (M₃) were tested with three moisture conservation practices i.e. Broad bed furrow (S₁), ridges & furrow (S₂), flat bed (S₃) in the investigation. The gross and net plot sizes were 4.5m x 18m and 3.6m x 15m, respectively. The crop was sown as per treatments with recommended spacing of 45cm x 5cm. The growth parameters were influenced by various treatments of mechanization practices. The growth parameters like plant height, number of functional leaves plant^-1, leaf area plant^-1, number of branches plant^-1, total dry matter accumulation plant^-1 were significantly higher in mechanization practices of full mechanization (M₁) treatment followed by partial mechanization (M₂) and no mechanization (M₃). The growth parameters were influenced by various moisture conservation. Broad bed furrow (S₁) recorded highest plant height (cm), maximum number of functional leaves plant^-1, leaf area plant^-1, number of branches plant^-1 and total dry matter accumulation plant^-1. The interaction effects between mechanization practices and moisture conservation not significantly influenced the growth and yield of soybean Thus to achieve higher soybean yield may be sown with full mechanization and broad bed furrow method.
