Abstract:
Effects of foliar nutrition of soybeans (cv.PB-I) with nitrogen and
molybdenum on the seed yield and its quality are reported. Nitrogen uptake
was positively affected by the foliar application of nitrogen. Foliar applcation
of 1% ammonium nitrate solution (30kgN/ha) during the early pod-fill period
has significantly increased the seed yield and the % protein in seeds. This
effect was further enhanced by incorporation of 0.05%ammonium molybdate
in the spray solution. Application of nitrogen: 3.0kgN/ha at two leaves tV22),
15kgN/ha at early flowering (RI-R2) and 30kgN/ha at early pod-fill (R4-R5)
periods had a better effect on the seed yield and the % protein in seeds. The
highest seed yield (1727 kg/ha), protein yield (703.4 kg/ha) and fats (351.6
kg/ha) were recorded in the fertilizer treatment where nitrogen was applied
together with molybdenum at all three stages of growth.
