Experiment Background
Sorghum [Sorghum bicolor L. Moench] is
the king of millets and considered the fourth
cereal crops after maize, wheat and rice. It
is an important food, feed and fodder crop.
In India, the area under Sorghum is
approximately 5127 lakh ha with an annual
production of about 4370 lakh tonnes and
an average productivity of 952 kg/ha. (GOI,
2021). In Gujarat, it is cultivated over an
area of 84.88 lakh ha with a production and
productivity of 115.33 lakh tonnes and 1359
kg/ha, respectively. (GOI, 2021).
Nitrogen use and demand is continuously
increasing day by day. Since, it is highly
mobile, it is subject to greater losses from
the soil-plant system. (Abd EI-Lattief, 2011).
Even under better management practices
30-50% of applied nitrogen lost through
different mechanism and hence, the farmer
is compelled to apply more than the actual
need of the crop to compensate the loss. In
this context, we want to access the effects
of sorghum productivity by the foliar
application of urea fertilizer and modern
Nano Urea over the conventional
recommended dose of fertilizers. It is
responsible for greenness, vigorous
growth, and overall crop development;
therefore, it must be available for plants in
adequate amounts. Nano Urea and liquid
fertilizers have emerged as promising
alternatives for ensuring high crop yield
while remaining environmentally friendly.
Liquid Nano fertilizer is currently the best
alternative to conventional urea fertilizer.
The aim of these experiments is to study the
effectiveness of urea and nano urea over
use of conventional urea fertilizers by the
foliar application at different crop growth
stages, and try to know the response and
fulfills its nitrogen requirement and leads to
higher crop productivity and quality in
comparison to conventional urea.
