Description A field experiment entitled “Effect of top dressing and foliar application of
organic nutrient sources on growth and yield of sorghum” was conducted during kharif,
2012 at Student farm, College of Agriculture, Rajendranagar, Hyderabad, Southern
Telangana climatic Zone of Andhra Pradesh. The soil of experimental site was sandy
clay loam with pH of 7.9, electrical conductivity 0.96 dSm-1, low in organic carbon
(0.69%), low in available nitrogen (221 kg ha-1) and high in phosphorus (86 kg ha-1) and
high in potassium (446 kg ha-1). The experiment was laid out in randomized block
design with nine treatments and three replications. The treatments comprises of Top
dressing of vermicompost @ 2.5 t ha-1(T1), Top dressing of vermicompost @ 5 t ha-
1(T2),Foliar spray of vermiwash @ 1% (T3), Foliar spray of vermiwash @ 2% (T4),
Foliar spray of humic acid @ 0.5% (T5), Foliar spray of humic acid @ 1% (T6), Foliar
spray of fulvic acid @ 0.5% (T7), Foliar spray of fulvic acid @ 1% (T8), 80:40:40 of
NPK fertilizers (T9).
The results of the experiment indicated significant influence of organic nutrient
management on plant growth and yield attributes.Maximum growth in terms of plant
height, leaf area index was recorded with application of foliar spray of fulvic acid @ 1%
(T8). Dry matter accumulations values were also significantly higher with foliar spray of
fulvic acid @ 1% (T8) on par with foliar spray of vermiwash @ 2 %( T4).
Days to 50% flowering and growth analysis parameters i.e CGR, RGR and NAR
did not vary significantly with different organic sources of nutrients
The yield attributes viz., number of ear heads m-2, number of grains ear head-1,
test weight, grain yield and stover yield were significantly enhanced with foliar spray of
fulvic acid @ 1% (T8) compared to other organic treatments.
Grain yield was higher with foliar spray of fulvic acid @ 1% (T8) followed by
top dressing of vermicompost @ 5 t ha-1(T2) which are on par with foliar spray of
fulvic acid @ 0.5% (T7), top dressing of vermicompost @ 2.5 t ha-1(T1) and foliar spray
of humic acid @ 1% (T6). Stover yield was higher with foliar spray of fulvic acid @ 1%
(T8) which was on par with top dressing of vermicompost @ 5 t ha-1(T2). Protein
content and post harvest soil status and physiochemical properties of soil did not vary
significantly with different organic sources of nutrients. The Nutrient uptake (N, P and
K) by crop at 60 days to harvest stages was higher with application of foliar spray of
fulvic acid @ 1% (T8) on par with top dressing of vermicompost @ 5 t ha-1(T2).
The highest gross returns, net returns and B:C ratio were recorded with
application of foliar spray of fulvic acid @ 1 % (T8) over other treatments.
