A field experiment was conducted at Agricultural Research Station (MPUAT), Borwat farm, Banswara (Rajasthan) during the rainy season of 2018 with objective to evaluate the performance of genotypes under varying plant spacing and fertility levels. The treatment consisted with two spacing viz 60x30 cm (55,555 plants/ha) and 60x 25cm (66,666 plants/ha, two fertility level and four sweet corn varieties viz. ASKH-1, Madhuri, Priya and Win-orange. The experiment was Layout in split plot desing with three replicatin. The results revealed that plant growth, green cob yield and economy of sweet corn varying significantly with plant spacing, fertility levels and genotypes. The closer plant spacing of 60x25cm was significantly increased plant population, green cobs, net return and B:C ratio in tune of 17.24, 29.19, 33.03 and 44.62% higher over wider spacing of 60x30cm, respectively. Plant height, green fodder yield and net return recorded higher with higher nutrient levels compared lower nutrient level. Among genotypes, Madhuri observed tallest (227cm) that found statically at par with priya and Win-orange and significantly 2.11% superior over ASKH-1. The maximum green cob yield (11.04t/ha), green fodder yield (16.98t/ha), net return (Rs. 75548/ha) and B:C ratio (2.17) obtained with ASKH 1 which green cobs yield was significantly 13.38, 31.58 and 57.77% higher than mathuri, priya and Win-orange, respectively. The significant effect of plant spacing, nutrient levels and genotypes recorded in term of net return obtained from green cob yield and green fodder yield. The effect of nutrient levels reported non-significant in B:C ratio. The closer spacing (60x25cm) gave more benefit than wider spacing. ASKH 1 gave higher B: C ratio than other varieties.
