SILVA, Kathia Maria Barbosa e; ALMEIDA, Francisco Aécio Guedes  y  SILVA, Paulo Sérgio Lima e. Peduncle and fruit yield, in six cropping seasons, of early dwarf cashew tree clones irrigated with different water regimes. Rev. Bras. Frutic. [online]. 2004, vol.26, n.3, pp. 474-477. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452004000300024.

The objective of this work was to evaluate peduncle and fruit yield in clone MS 076 and in a clonal population of drip-irrigated, early dwarf cashew trees propagated by layering, in six cropping seasons. In order to meet the increased water requirements of the crop resulting from plant growth and development, irrigation during the dry season was performed daily according to the following water regime: 15 min/plant/day during the 1st year, 30 min/plant/day during the 2nd year, 45 min/plant/day during the 3rd year and 60 min/plant/day during all subsequent years. Water was supplied by one drip emitter/plant, at an (adjustable) flow rate of 36 L/h.The research was carried out in Fortaleza-Ceará, Brazil, and a random block design was utilized, with five replicates and split-plots. The clones were assigned to plots and the cropping seasons were considered as subplots. The clonal population was superior to the clone only with regard to number of nut shells (NNS), and solely in the first season. The clone was superior to the population as to NNS and peduncle yield (PY) in the second season, and also with regard to the three evaluated traits - NNS, PY, and nut shell yield, in the last three cropping seasons.
