Abstract: An experiment was conducted at the college Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat during Rabi season of the year 2015-16 with a view to study the response of organic acids and inorganic fertilizers on growth, yield and quality of Rabi maize (Zea mays L.). Maize variety HQPM 1 used in experiment. The experiment consisted fifteen treatment combinations comprised of three treatments of inorganic fertilizers viz., F1: 50 % RDF, F2: 75 % RDF and F3: 100 % RDF (150-60-0 NPK kg ha-1) and five treatments of organic acids viz. M1: Control, M2: Humic acid @ 5 kg ha-1, M3: Humic acid @ 10 kg ha-1, M4: Citric acid @ 2.5 kg ha-1 and M5: Citric acid @ 5 kg ha-1 were tested in a factorial randomized block design with four replications. Significantly the highest cob length (16.91 cm), number of grain cob-1 (499), number of cob plant-1 (1.79), stover yield (7776 kg ha-1), protein content of grain and stover (10.43 and 2.87 %, respectively) were observed in case of application of 100 % RDF. While higher plant height at harvest (205.22 cm) and grain yield (5149 kg ha-1) were observed in case of application of 100 % RDF and it was remained at par with treatment 75% RDF. Among -1 (M5), humic acid 5 kg ha-1 (M2) and citric acid @ 2.5 kg ha-1 (M5). Higher level of organic acids treatments, significantly higher cob length (16.24 cm), number of grain cob-1 (486), grain yield (5103 kg ha-1) and protein content in grain (10.36 %) were observed under the application of 10 kg ha-1 humic acid and it was remained at par with application of citric acid @ 5 kg ha-1 (M5) and humic acid 5 kg ha-1 (M2). Plant height (204.78 cm) was observed in case of application of 10 kg ha-1 (M3) humic acid and it was remained at par with application of citric acid @ 5 kg hacob plant-1 (1.73) and stover yield (7507 kg ha-1) were observed in application of 10 kg ha-1 (M3) humic acid and it was remained at par with application of citric acid @ 5 kg ha-1 (M5). The highest protein content in stover (2.77 %) was observed in case of application of 10 kg ha-1 humic acid (M3). Higher net realization of ₹ 51101 ha-1 and higher B.C.R. value of 2.57 were recorded in 100 % RDF. Among organic acids resulted in to higher net realization ₹ 55449 ha-1 with B.C.R. of 3.03.
