Description The field experiment entitled, “Studies on growth, forage yield and quality of maize (Zea
mays L.) as influenced by integrated nutrient management” was conducted during kharif season
of 2010 at Forage Research Farm of Chaudhary Charan Singh Haryana Agricultural University, Hisar
with the objective to study the effect of organic, inorganic and biofertilizer sources of nutrients on
growth, yield, quality, NPK content, their uptake and economics of forage maize under different
combination of treatments. Ten different treatments were taken for the experimental study i.e.
Control (T1), Azotobacter chroococcum (T2), 100 per cent N through farm yard manure (FYM) (T3), 100
per cent recommended dose of fertilizer (RDF) (T4), 75 per cent RDF + Azotobacter chroococcum (T5 )
75 per cent RDF + 25 per cent N through FYM (T6), 75 per cent RDF + 25 per cent N through FYM
+ Azotobacter chroococcum (T7), 50 per cent RDF + Azotobacter chroococcum (T8), 50 per cent RDF + 50
per cent N through FYM (T9), 50 per cent RDF + 50 per cent N through FYM + Azotobacter
chroococcum (T10) were laid out in Randomized Block Design with three replications.
The growth parameters viz., plant height (cm), dry matter accumulation (g/plant), LAI,
LAD, CGR, Leaf: stem ratio were significantly higher in 100 per cent RDF and 75 per cent RDF + 25
per cent N through FYM + Azotobacter chroococcum (T7) treatments than rest of the treatments. Green
forage yield in treatments; T4 (460 q/ha), T7 (443 q/ha), T6 (426 q/ha) and T10 (408 q/ha) were 93.2,
86.1, 78.9 and 71.4 per cent higher respectively over the control. Dry matter yield in treatments; T4
(114.2 q/ha), T7 (109.8 q/ha), T6 (105.1 q/ha) and T10 (100.8 q/ha) were 80.9, 74.0, 66.5 and 59.7 per
cent higher respectively over the control The highest N and P content (%) was recorded in T4 (1.14
and 0.16) followed by T3 ( 1.08 and 0.14) but maximum K content (%) was recorded in T3 (1.15) and
closely followed by T1 0 (1.13). The uptake was 168.1, 139.6 and 103.5 per cent higher in T4
compared to T1, T2 and T8 treatments, respectively. The maximum crude protein content was 6.90%
in T4 and it was followed by T3 (6.76%) and T7 (6.57%) treatments, respectively. Maximum in-vitro
dry matter digestibility (54.1%) was in 100 per cent N through FYM in the control (47.5%) and
digestible dry matter yield (58.9 q/ha) was also maximum with the use of 100 per cent RDF.
Maximum gross returns (Rs. 41400 /ha), net returns (Rs. 17715 /ha) and B: C ratio (1.74) were found
in the treatment T4 (100% RDF) and T7 (75 per cent RDF + 25 per cent N through FYM + Azotobacter chroococcum)
treatment with values of Rs. 39870/ha (Gross returns), Rs. 15665/ha (Net returns) and 1.64 (B: C ratio).
