The Studies were initiated to evaluate the influence of seed priming technique (15 per cent Azospirillum + 15 per cent phosphobacteria, 10per cent P. fluorescens + 20per cent Humic acid, 15 per cent Azophos + 10 per cent P. fluorescens and hydro priming technique) in conjunction with crop management techniques viz., nutrient supplementation as basal (humic acid @ 10kg ha−1, micronutrient 5kg ha−1) and foliar (diammonium phosphate 2 per cent, humic acid 0.1per cent, sea weed extract 0.5per cent) along with NPK application. The results revealed that seeds primed with 20 per cent humic acid + 10 per cent P. flurescense, applied with humic acid @ 10 kg ha−1 as basal application and sprayed with 0.5% sea weed extract improved the productivity of maize and the grain recovery. On comparison of seed and crop management techniques the contribution of seed management technique was higher than crop management techniques. The evaluated seed and crop management techniques were further test verified at Bhavanisagar both during Kharif and Rabi season, which conformed the influence of identified seed and crop management techniques on enhanced productivity and nutrient status of the grain, recommending it as package for commercial hybrid production irrespective of season and location.
Highlights
• 20% humic acid + 10%P. flurescense priming gave best results
• Seaweed (0.5%)foliar spray, 10kg/ha humic acid + NPK gave best results
• Kharif season suitable for MaizeCOH(M)5.
