An experement was conducted during winters of 2000-01 and 2001-02 to find out effect of planting time, fer- tility level and phosphate-solubilizing bacteria on winter maize (Zea mays L.) after rice (Oryza sativa L.) at Varanasi, on sandy-loam soil conditions of eastern plain zone of Uttar Pradesh. Delay in planting from 15 De- cember to 30 December decreased the maize yield by 19.25% with mean reduction of 82.7 kg maize yieldlhal day. Fertility level up to 180, 90 and 60 kg N, P,O,and K,O/ha significantly improved growth, yield and yield at- tributes. On the basis of the 2 years average data (pooled), the increase in maize yield was 52.6 and 82.97% with 120, 60 and 40 kg N, P,O, and K,Olha and 180, 90 and 60 kg N, P,O, and K,Olha, respectively, over 60, 30 and 20 kg N, P20,and K20/ha. Phosphate-solubilizing bacteria (PSB) inoculation alone or along with 5 tonnes FYMIha and no-PSB inoculation also differed significantly with regarding to above parameters. The maximum maize yield was abtained with PSB inoculation along with 5 tonnes FYMIha, whereas no-PSB inoculation gave the minimum maize yield.References
