SUNFLOWER GROWTH AND YIELD IN RESPONSE TO COMBINED APPLICATION OF FARMYARD MANURE AND INORGANIC FERTILIZERS (NITROGEN AND PHOSPHORUS)

Abstract

The research was conducted in 2022 in the
Agronomy Student's Experiment Farm at
Sindh Agriculture University Tando Jam. It
used a complete block design with
randomization. The main goal was to
evaluate how much adding different amounts
of FYM and nitrogen-phosphorus affected
the growth and seed production ability of
sunflowers. The research had five different
FYM options and nitrogen-phosphorus
levels. The HO-1 variety was given these
treatments. The assigned treatments were as
follows: T1 = control (no FYM, 0 kg/ha
nitrogen and 0 kg/ha phosphorus); T2 =
adding a small amount of farmyard manure
plus some extra nutrients in the form of
nitrogen at a rate of 30kg per hectare, along
with an additional quantity of 15 kg per
hectare. The best results were seen in T5 (5
tons of farm FYM + fertilizers, with 120 kg
per hectare of nitrogen and 50 kg per hectare
of phosphorus). This method resulted in the
most plants on a square meter (9.11), the
tallest plant growth at about 248.8 cm high;
T5 was closely followed with good results (a
lot of FYM plus 120 kg per hectare nitrogen
and 50 kg phosphorus). The research
indicates that the optimal combination for
enhancing sunflower growth and yield
includes applying 120 kg ha-1 of nitrogen, 50
kg ha-1 of phosphorus, and incorporating 5
tons of FYM
