Influence on crop growth and yield of sweet corn under vegetable intercropping systems and nutrient management


Nandini KS, Gangadhar K, Sumathi V, Nagamani C and Manasa SR

A field experimentation was conducted at wetland farm, S.V. Agricultural College, Tirupati of Acharya N.G. Ranga Agricultural University during rabi, 2020 to study and evaluate the crop growth and yield of sweet corn under different vegetable intercropping systems and nutrient management. The research was carried out in split plot design and replicated thrice. The treatments consisted of three intercrops viz., sweet corn + knol khol (I1), sweet corn + radish (I2) and sweet corn + onion (I3) as main plots and four nutrient levels viz., 100 % RDF to sweet corn alone (N1), 100 % RDF to sweet corn + 75 % RDF to intercrop (N2), 100 % RDF to sweet corn + 50 % RDF to intercrop (N3) and 100 % RDF to sweet corn + 25 % RDF to intercrop (N4) as sub plots. The results revealed that among the intercrops, sweet corn + knol khol (I1) has recorded significantly higher plant height, leaf area index, dry matter production, green cob yield (6090 kg ha-1) and green fodder yield (12304 kg ha-1). However, among the nutrient management practices, 100 % RDF to sweet corn + 75 % RDF to intercrop (N2) has recorded significantly higher plant height, leaf area index, dry matter production, green cob yield (6211 kg ha-1) and green fodder yield (12546 kg ha-1).
