Bagavathi Ammal U, Karuna Prabu GR and Pradip Dey

The gradient and test crop experiments were conducted at farmer’s holding of Karikalampakkam village in Nettapakkam commune of Puducherry district, U.T of Puducherry during 2017-2018. The study area comes under Bahour soil series which occupies 12.72 per cent of Puducherry district. This soil is classified as fine, mixed isohyperthermic, TypicUstropept. The fertility gradient experiment was conducted with hybrid maize (Kavery super 244) by adopting Ramamoorthy’s inductive methodology and variations in soil fertility were created by applying three graded doses of fertilizer N, P2O5 and K2O viz.,N0P0K0, N1P1K1 and N2P2K2. After the creation of fertility gradient in the experimental field, the test crop experiment was conducted with bhendi hybrid (Green gold plus). The treatment consists of four levels of N (0,100,200 and 300 kg ha-1), P (0, 50,100 and 150 kg ha-1) and K (0, 50,100 and 150 kg ha-1) and three levels of FYM (0, 6.25 and 12.5 t ha-1). There were 21 fertilizer treatments along with three controls which were randomized in each strip in such a way that the treatments occurred in both directions, NPK alone, FYM applied @ 6.25 t ha-1 and 12.5 t ha-1 were super imposed across the strips and was conducted as fractional factorial design.
