Abstract: A field experiment was carried out during Kharif season 2015 taking maize (variety Ganga Kaveri 41-19) to study the Influence of Fertility gradients and FYM levels on growth, productivity and quality parameters of Maize. The experiment was laid out with different Nine treatment combinations of 3 fertility gradients (L1: 60 N: 40 P2O5 : 30 K2O kg ha-1, L2: 120 N : 80 P2O5 : 60 K2O kg ha-1 and L3: 240 N, 160 P2O5,120 K2O kg ha-1) with 3 FYM level (F0: 0 t FYM ha-1, F1: 5 t FYM ha-1 and F2: 10 t FYM ha-1) was laid in factorial randomized block design consisted of nine combinations (L1F0, L1F1, L1F2, L2F0, L2F1, L2F2, L3F0, L3F1, L3F2) followed under optimum agronomic management practices with three replications. Result revealed that the Significant effect of different treatment on yield attributing characters the highest value of cob length (14.96, 14.01 cm) and girth (13.99, 13.03 cm), number of grains line-1 of cob (21.90, 21.10), number of lines cob-1 (13.30, 12.90), numbers of grain cob-1 (288.70, 272.60), grain weight cob-1 (58.54, 53.28 g), test weight (202.25, 193.98 g) and harvest index (22.93, 22.63%) was observed in treatment L3 : ( 240:160:120; N:P2O5:K2O kg ha-1) and F2 (10 t FYM ha-1) respectively and lowest value was observed in treatment L1 : ( 60:40:30; N:P2O5:K2O kg ha-1) and F0 (0 t FYM ha-1). Similarly significant effect of different treatment combinations highest values of cob length (15.71 cm) and girth (15.71 cm), number of grains line-1 of cob (22.2), number of lines cob-1 (13.7), numbers of grain cob-1 (303.7), grain weight cob-1 (64.18 g), test weight (211.35 g) and harvest index (23.11%) were obtained in treatment combinations L3F2 :( 240:160:120; N:P2O5:K2O kg ha-1 + 10 t FYM ha-1).The lowest value of cob length (11.20cm) and girth (9.39 cm), number of grains line-1 of cob (18.4), number of lines cob-1 (10.9), numbers of grain cob-1 (201.8), grain weight cob-1 (31.48 g), test weight (155.95 g) and harvest index (21.61%) were obtained in treatment combinations L1F0 :( 60:40:30; N:P2O5:K2O kg ha-1 + 0 t FYM ha-1). The yield of maize grain and stover was affected significantly due to various treatment combinations. The highest yield of grain and stover was recorded in combinations L3F2 where higher dose of fertilizer was applied (240:160:120; N:P2O5:K2O kg ha-1 + 10 t FYM ha-1) yielding 3387 kg ha-1 and 11317 kg ha-1, respectively. The lowest yield of grain and stover was recorded in combinations L1F0 where lower dose of fertilizer was applied L1F0 (60:40:30; N:P2O5:K2O kg ha-1 + 0 t FYM ha-1) yielding 2167kg ha-1 and 7863 kg ha-1, respectively. The significant effect of the treatment on crop quality parameters with higher application of fertilizers with FYM in treatment combination L3F2 ( 240:160:120; N:P2O5:K2O kg ha-1 + 10 t FYM ha-1) improved the grain protein (10.94%) and starch content (66.73 g/100g). However, integrated application of fertilizer with organic manure noticed remarkable maximum protein and starch content in maize. As regards economic viability with different treatment combinations of fertilizer levels with FYM levels significantly affected the maximum cost of cultivation and GMR (58735, 55360 Rs ha-1 respectively) having recorded in treatment combination L3F2, but highest value of NMR (12100 Rs ha-1) was found in treatment combination L3F0 followed by L2F0 and highest B:C ratio was recorded in same treatment combination L3F0 (1.30).
