Juan G. R., Bernal V. P. and Malagon G. Optimal seedtime for irrigated and no irrigated urban agriculture on the northern coast of Havana.

Hydraulic Engineering Vol. 19, No. 3: 58-61, 1998/. / Presented to XII for Science and Technology Forum Municipality of East Havana,1997/.

Optimal seedtime for agricultural crops and forest plants in function of water requirements and precipitation on the north coast of Havana was studied. The average annual precipitation for the northern coast of Havana is 1241 mm, with a distribution of rainfall of 77% for the wet period and 17% for the dry.

It was found that in no irrigation conditions the optimal seedtime corresponds to months from September to December as a result of the high rainfall in the period from September to October and the arrival of cold fronts during the winter. Sowing with irrigation is from November to May, which is stretched a month in relation to the conditions of Cuba. Annual evapotranspiration in the northern coast of Havana is 1545 mm / year with a net annual demand of 6837 m3/hectare considering a mean year and a coefficient of utilization of the rains of 0.70.
