Agronomic and economic evaluation of baby corn under varying row spacing and phosphorus levels in irrigated black soils of Andhra Pradesh

Abstract

An efficient production technology is essential for maximizing remunerative yields of baby corn, including both ear and fodder (green and dry) components. Optimal crop geometry enhances productivity by improving resource-use efficiency and light interception. Additionally, the crop’s high plant density and short growth duration further emphasize the need for timely and adequate nutrient supply. In light of this, a field experiment was conducted at the Fodder Production Farm, Livestock Research Station, Lam, Guntur to study the effect of different row spacing (40 × 15, 45 × 15, and 50 × 15 cm) and phosphorus levels (40, 50, and 60 kg ha⁻¹) on the yield and economics of baby corn. The results of experiment revealed that, baby corn at a spacing of 50 × 15 cm with the application of 50 kg ha⁻¹ phosphorus at sowing is beneficial for farmers in the Krishna Zone of Guntur, Andhra Pradesh, as it ensures higher net returns along with ample green fodder availability.
