Abstract:
The field experiment was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U. P.) during Kharif season of 2 consecutive years 2008 and 2009. Twenty one treatment combinations comprised of three levels of fertility (120: 60:60 kg NPK ha-1, 150: 75: 75 kg NPK ha-1 and 180: 90: 90 kg NPK ha-1) with seven hybrids (SHP-O1, SHP-02, SHP¬03, SHP-04, SHP-05, SHP-06 and NDRH-2) were executed in split plot design keeping fertility levels in main plot with four replications. The soil of experimental plot was silt loam in texture with low in organic carbon and nitrogen, medium in phosphorus and high in potassium. The crop received normal recommended agronomic and plant protection measures. All the growth characters i.e. plant height, number of tillers and dry matter accumulation increased significantly with increases fertility levels at all the growth stages of the crop. Highest plant height, number of tillers and dry matter accumulation were found with fertility levels N180 P90 K90 kg ha-1 witch was at par with N150 P75 K75 kg ha-1 and significant superior over N120 P60 K60 kg ha-1 at all the growth stages of crop. Maximum plant height, number of tillers and dry matter accumulation were recorded with hybrid SHP-04 which was at par with hybrid NDRH-02. At harvest plant height was recorded (133.97 and 135.72 cm), number of tillers (455.14 and 457.00 m¬-2) and dry matter accumulation (1521.18 and 1569.61gm-2) with hybrid SHP-04. Grain yield increased with increase in fertility levels and highest grain yield (65.36 q ha-1 and 67.54 q ha-1) were recorded under highest fertility level of N180 P90 K90 kg ha-1 (Table-I), which showed an increase of 8.9 and 9.9% grain yield over N120 P60 K60 kg ha-1 and remained at par with N150 P75 K75 kg ha-1 during both of the years
