Abstract

Afield experiment was conducted in a sandy loam texture to study effect of
phosphate fertilizer type and its levels on growth and yield of wheat (Triticum
aestivum L.) in a gypsiferous soil. The experiment was conducted according to
Randomized Complete Block Design (RCBD) with three replications used two
types of phosphate fertilizers (TSP-Triple Super Phosphate and DAP- Di
Ammonium Phosphate(. Phosphorus fertilizer was applied in six levels (0, 20,
40, 60, 80 & 100) kg P ha-1 with symbols P1, P2, P3, P4, P5 and P6. The total plots
were 36 experimental units. Nitrogen fertilizer added to all treatments at a rate
of 200 kg N ha-1
in Urea form (46% N) applied at agriculture and at 45 days
after germination. Potassium fertilizer added at rate of 165 kg K ha-1
in the form
of potassium sulfate(43% K). The results showed significant increased (plant
height, spike number, spike weight, straw and grains yield) in all parameters for
both fertilizer types. Results refer TSP fertilizer better than DAP fertilizer in the
growth criteria's and yield components
