A field experiment was conducted at Udaipur during rainy (kharif) season of 2014, to study the “Performance of Maize (Zea mays L.) Hybrids at Different Fertility Levels under in Maize Grown Areas of Rajasthan” of the maize–genotypes ‘CMH 08-292’ recorded significantly highest dry-matter accumulation at various stages and yield attributes. Consequently, highest grain (5753.33 kg ha-1), stover (9001.11 kg ha-1) and biological yields (14754.44 kg ha-1) were recorded with CMH-08-292 followed by PHM-3. Among the fertility levels, SSNM recorded highest plant height (264.62 cm), dry matter accumulation (220.89 g plant-1) at harvest. Application of SSNM significantly increased yield components viz. number of cobs plant-1 (1.25), cob length (18.14 cm), grains weight cob-1 (93.08 g), 1000 grains weight (228.72 g) and shelling per cent (86.31%) consequently grain (5092 kg ha-1), Stover (7886.67 kg ha-1) and biological yield (12978.67 kg ha-1) over RDF and farmer’s practice.
