An Experiment on Integrated nitrogen management on
fodder maize and its residual effect on fodder cowpea was conducted during kharif-rabi
season of 2021-22 and 2022-23 at Main Forage Research Station Anand
Agricultural University, Anand 388110 (Gujarat) with twelve integrated nitrogen
management treatments with three replications. All targeted treatments imposed
in kharif fodder maize crop only while in second season (Fodder cowpea),
Common application of seed treatment to fodder cowpea. Significantly higher dry
matter intake (1.92 and 1.97%) of fodder cowpea was observed higher in first
and second year, respectively by residual effect of 125% RDN (100 kg N/ha) +
Micronutrient enriched FYM 0.5 t/ha. In first year, dry matter digestibility
(62.88%), total digestible nutrient (58.22%), relative feed value (92.60%) and
relative feed quality (89.86%) was reported significantly in higher in residual
treatment where application of 125% RDN (100 kg N/ha) + Micronutrient enriched
FYM 0.5 t/ha fb Bio NP drenching 1 L/haat 15,30 and 45 DAS.
In second year, residual effect of 125% RDN (100 kg N/ha) + Micronutrient
enriched FYM 0.5 t/ha treatment noted significantly higher dry matter
digestibility (64.22%), total digestible nutrient (60.45%), relative feed value
(98.50%) and relative feed quality (97.45%).
