Abstract: The field and laboratory experiments were during kharif 2014-15 to study the influence of nutrients levels and time of application on plant growth, seed yield and quality of maize hybrid (Zea mays L.)-Hema. The study comprised of four treatments and five replications. The results revealed that among the different nutrient levels of applications T3: 225:112.5:60 NPK kg ha-1 ( 20 % N, 100 % P & K at sowing, 25 % N at 4th leaf stage, 30 % N at 8th leaf stage, 20 % N at tasseling stage and 5 % N at grain filling stage) recorded highest plant height at 4 th leaf and 8 th leaf stage (24.04 and 50.32 cm), cob length (23.46 cm), cob width (3.65 cm), seed yield per cob (123.05 g), Bulk seed yield (26.68 q ha-1) , processed seed yield (24.38 q ha-1) and also recorded highest quality parameters like seed germination (95.60 %), SVI-1 and SVI-II (2570 and 6284). Accelerated ageing test was also conducted for these four treatments with a period of 0, 1, 2, 3, 4, 5, 6, days among these treatments highest field emergence (87.38 %) and germination (90.05 %) was recorded in T3. Economics and cost benefit ratio was calculated. The Marginal cost production and marginal return differed due to different nutrient level treatments. Marginal cost production and marginal return was highest in T3 (Rs 69,524 and Rs 1,49,430), while lowest was observed in control T4 (Rs 59,905 and Rs 1,06,710).
