Abstract:
This study was conducted to
investigate the effect of different
phosphorus doses (0, 15, 30, 40 and 70 kg
ha-1) on chickpea (Cicer arietinum L.)
cultivars at Diyarbakir, Southeast Anatolia
of Turkey over two years at late spring. The
effect of phosphorus on plant height and
number of branches plant-1 was nonsignificant.
Number of branches plant-1 was
different response to phosphorus doses,
although statistically was not significant.
Number of pods and seeds plant-1 were
affected by phosphorus treatment. Although
100 seed weight was not affected by
phosphorus applications, cultivar x doses
interaction was important. Phosphorus doses
were significant for yield, but yield
apparently did not increase. Start dose, 15
kg phosphorus ha-1, was initially increased
the yield, and 30 kg phosphorus ha-1
application slightly was increased. The
highest number of pods and seeds at 30 and
70 kg P ha-1, compared only one of these
control and 15 kg P ha-1. Grain yield was
increased to 16 and 12% with the
application of 30 and 40 kg P ha-1,
respectively, when compared with control
dose. Chickpea cultivars showed low
response to P application. Phosphorus
fertilization could not be effective due to
late sown. Early sown and irrigation supply
can be advisable for more effectiveness
phosphorus intake in this region.
