Description A field experiment on “Effect of integrated nutrient management on
growth, yield and quality of forage sorghum (Sorghum bicolor L. Moench)”
conducted during kharif 2006 season on sandy loam soil low in available N,
medium in available P and rich in available K at Forage Research Farm
Department of Plant Breeding, CCS Haryana Agricultural University, Hisar.
The experiment consisting of ten treatments viz., control (T1), Azotobacter (T2),
100% RDF (T3), 15 t FYM/ha (T4), 25% RDF + 11.25 t + FYM/ha (T5), 50%
RDF + 7.50 t FYM/ha (T6), 75% RDF + 3.75 t FYM/ha (T7), 25% RDF +
11.25 t FYM/ha + Azotobacter (T8), 50% RDF + 7.50 t FY/ha +Azotobacter
(T9) and 75% RDF + 3.75 t FYM/ha + Azotobacter (T10) was replicated thrice
in a randomized block design.
The results indicated that growth parameters viz., plant height, dry
matter accumulation, LAI, LAD, CGR and leaf: stem ratio were significantly
higher in the treatment having 100 per cent recommended dose of chemical
fertilizers than other treatments, except the treatment having 75% RDF + 3.75 t
FYM/ha + Azotobacter. The application of 100% RDF further significantly
improved the green fodder and dry matter yield over the remaining treatments.
The treatments having substitution of 25 per cent N through FYM along with
75% RDF + Azotobacter proved superior for green fodder and dry matter yield
over other combinations of organic and inorganic fertilizers. The highest N, P,
K, crude protein content and IVDMD (%) in sorghum fodder was recorded
with the application of 15 t FYM/ha whereas the uptake of these nutrients,
crude protein and DDM yield was higher when 100% RDF was applied to the
crop. The residual N, P and K content in soil was observed to be higher with
the application of 15 t FYM/ha. The highest net returns of Rs.10,014/- were
obtained with the application 100% recommended dose of fertilizers.
