Abstract: A field investigation was undertaken on “Influence of plant population and fertilizer levels on growth, yield and quality parameters of quality protein maize (Zea mays L.) in irrigated ecosystem†during the Kharif 2015 at Agriculture Research Station, Siruguppa. It is situated on the latitude of 15o38’ N, longitude 76o54’ E, 380 m elevation from MSL belongs to Northern Dry Zone (Zone 3) of Karnataka. The soil of the experimental site was medium deep black cotton soil with organic carbon content of 0.41 per cent, low in available N (220 kg ha-1), medium in available phosphorus (21 kg ha-1) and high in potassium (375 kg ha-1) content. The experiment was laid out in a split plot design with three replications. Trail consisted of sixteen treatment combinations of four plant populations viz., S1:1,11,111, S2:83,333, S3:74,074 and S4:66,666 plants ha-1 in main plots and four fertilizer levels, F1:150:75:37.5, F2:187.5:93.75:46.88, F3:225:112.5:56.25 kg NPK ha-1 and F4:Nutrient Expert based target yield 10 t ha-1(NE) in sub plots. The hybrid HQPM-1 was used in the investigation. The experimental results indicated that, among the plant populations, 1,11,111 plants ha-1 recorded higher grain (7839 kg ha-1), stover yield (13114 kg ha-1) compared to other plant populations. But minimum total dry matter production (251.21 g plant-1), number of green leaves (6.35/plant) and leaf area (2452 cm2) were registered with higher plant population (1,11,111 plants ha-1) compared to other plant populations. Higher protein content, oil per cent and starch contents were recorded with 66,666 plants ha-1. Among the fertilizer levels significantly higher grain yield (8023 kg ha-1) and stover yield (13434 kg ha-1) was registered with the application of 225:112.5:56.25 NPK kg ha-1 than other fertilizer levels. Similar trend in number of leaves, leaf area, leaf area index, plant height, protein, oil and starch contents were noticed with higher fertilize level compared to other fertilizer levels.
