Abstract:
An experiment was planned and executed over the Research Farm of LPU, to understand the impact of seed priming with Mg (NO₃)₂ on morphological changes and the yield of sorghum cultivars. The varietal response showed that V₂ (Dairy Green) performed well for most of the morphological and yield parameters such as plant height, fresh and dry weight, number of leaves, leaf area, LAI, SPAD readings and biological yield (235.7 cm, 345.7 g, 85.4 g, 9.2, 1555.2 cm² plant^-1, 7.1, 5.2, 37.8, 30.5, 341.58) while V₃ (Shri Ram Green) was recorded better for the economic yield and HI% as compared to rest of the varieties (Fat boy and Dairy green). However, among the concentrations of seed priming treatment, C₂ (7.5 mM) was recorded better for all the morphological as we as yield of sorghum (229.9 cm, 319.2 g, 79.4 g, 9.4, 1535.0 cm² plant^-1, 7.3, 5.1, 38.2, 31.0, 341.11) as compared to rest of the concentrations of the priming treatments C₁ and C₃ (5.5mM and 9.5 mM) including control C₀ (Non primed seed). Results of statistics at (P>0.05) showed that most of the parameters were recorded as significant while the interaction of VXC showed a non-significant difference for the parameters such as the number of leaves, leaf area, and LAI at harvest and SPAD at 60 DAS.
