In an attempt to study the relationship between seed zinc content and seedling vigour, hundred rabi sorghum genotypes were raised during rabi 2009-10.The genotypes at 30 DAS were categorized as low,medium and high vigour types based on drymatter accumulation.In high vigour genotypes the total dry matter ranged from 10.21-12.35g and in medium it ranged from 9.07-10.19g and in low vigour ranged from 6.25-8.84g plant-1. High vigor genotypes had higher zinc content 3.13-4.49 and low vigour types 1.96-2.66 mg100g-1. Thus there was correlation between seedling vigour and seed zinc content. To enhance the seed zinc content in selected genotypes in the field, zinc sulphate @ 10 kg/ha in combination with organics (1t/ha) at the time of sowing increased seed yield by 23% and seed zinc content by 23.6%.Root and shoot growth of sorghum increased considerably due to addition zinc at early stage.Low zinc types responded higher than high vigour types.Thus, zinc has differential response in sorghum...
