“…During initial year of plantation, irrigation frequency has little influence on growth parameters. Similar types of results were reported in pomegranate (Chopade and Gorantiwar, 1998) and fig (Andrade ., 2014) where irrigation methods and frequencies did not have much influence on the plant growth during initial years. During the year 2011-12 and 2012-13, maximum increase in plant height and plant spread was observed in 1 day followed by 2 days irrigation interval treatment.…”

“…The water requirements of fig trees (Ficus Carica L.) were studied in Brazil by Andrade et al (2014) and Souza et al (2014) using the SWB approach in drip irrigated orchards. The experiment presented by Andrade et al (2014) consisted of two irrigation treatments with different watering frequencies scheduled to avoid water stress. The K c mid resulted higher for the high irrigation frequency.…”

The present study reviews the research on the FAO56 crop coefficients of fruit trees and vines performed over the past twenty years. The main objective was to update information and extend tabulated single (K c ) and basal (K cb ) standard crop coefficients. The selection and analysis of the literature for this review have been done to consider only studies that adhere to FAO56 method, computing the reference ET with the FAO Penman-Monteith ET o equation and field measuring crop ET with proved accuracy. The crops considered refer to vine fruit crops, berries and hops, temperate climate evergreen fruit trees, temperate climate deciduous fruit trees and, tropical and subtropical fruit crops. Papers satisfying the conditions expressed above, and that studied the crops under pristine or appropriate eustress conditions, were selected to provide for standard K c and K cb data. Preference was given to studies reporting on the fraction of ground cover (f c ), crop height (h), planting density, crop age and adopted training systems. The K c and K cb values obtained from the selected literature generally show coherence relative to the crop biophysical characteristics and reflect those characteristics, mainly f c , h and training systems. The ranges of reported K c and K cb values were grouped according to crop density, particularly f c and h, and were compared with FAO56 (Allen et al., 1998) previously tabulated K c and K cb values, as well as by Allen and Pereira (2009) and Jensen and Allen (2016), which lead to define update indicative standard K c and K cb values. These values are aimed for use in crop water requirement computations and modeling for irrigation planning and scheduling, thus also aimed at supporting improved water use and saving in orchards and vines.

“…Studies show the efficiency of trickle irrigation systems compared with the other systems, in different crops, without negatively influencing productivity (Andrade et al, 2014;Carvalho et al, 2014;Geisenhoff et al, 2015;Uribe et al, 2013).…”

ESTIMATION OF THE KINETIC HEAD COEFFICIENT (k) BASED ON THE GEOMETRIC CHARACTERISTICS OF EMITTER PIPES

ABSTRACT:The objective of this study was to determine the variability of the head loss as a function of the emitter geometry as well as to develop a relation between local head loss caused by the emitter insertion and geometric characteristics of the emitter pipe, using index of obstruction for dripper pipes with non-coaxial emitters. For this, an experimental bench was developed to control the system and obtain the variables pertinent to the study. From the value of the total head loss in the emitter pipe and the value obtained with calculation of the distributed head loss in the pipe, the difference of these values was local head loss caused by the insertion of the emitter. Total head loss in the emitter pipe and local head loss on the emitter presented a potential relation with flow rate. The kinetic head coefficient (k), for each emitter studied, was obtained from the local head loss on the emitter and the kinetic head. A model for estimating the k coefficient based on the obstruction index was then generated.
