SUMMARY
A field experiment was conducted at Research Farm Area of Forage Section, Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar during kharif 2010. The experiment was carried out in randomized block design with ten treatments viz., Control, seed treatment with Azotobacter, 100 per cent N through FYM, 100 per cent RDF, 75 per cent RDF+Azotobacter, 75 per cent RDF+25 per cent N through FYM, 75 per cent RDF+25 per cent N through FYM+Azotobacter, 50 per cent RDF+Azotobacter, 50 per cent RDF+50 per cent N through FYM and 50 per cent RDF+50 per cent N through FYM+Azotobacter. The growth indices Leaf Area Index and crop growth rate were observed significantly higher with 100 per cent RDF followed by 75 per cent RDF+25 per cent N through FYM+Azotobacter. Availability of N, P and K in the soil under most of the treatments decreased after the crop harvest than before the sowing of the crop. The highest NPK status in the soil after the harvest of crop was recorded in the treatment 100 per cent N through FYM.
Key words: Maize, leaf area index (LAI), crop growth rate (CGR), Azotobacter, NPK uptake
