| Sumario: | An experimental greenhouse was conditioned in Cuernavaca,
Morelos, Mexico, to carry out the production of poinsettia
crop under protected ambient conditions, from August to
November 2012. Giving an accurately follow for both, the
climatic conditions and the phenological development of
the crop. The following meteorological parameters were
recorded every 15 min, inside and outside the greenhouse:
Wind speed and direction, solar radiation, temperature and
relative humidity. For reference, the precipitation was also
measured outside the greenhouse. The irrigation requirement
or evapotranspiration (ET) Real (ETr) of the poinsettia
was measured with eight weighing microlysimeters in
polyethylene pots 15 cm in diameter with leaf/tezontle/
coir substrate in proportion of 60:20:20, resulting at 40,
70, 150 and 122 mL day-1 at the weeks 1, 4, 10 and 13 after
transplanting (DAT), respectively. Based on data from
weather sensors reference ET (ETo) is estimated using
the algorithm of Penman Monteith (PM) in and out of the
greenhouse. The poinsettia crop coefficient (Kc) was weekly
and monthly measured in the greenhouse based in the inside
climate information, resulting in Kc of 0.22, 0.44, 0.54 and
0.43 at the weeks 1, 5, 11 and 13 DDT and 0.21, 0.36, 0.39
and 0.3 at months 1, 2, 3 and 4 DDT, respectively |
