This work assessed the effects of sustained (during whole berry growth) and regulated (at post-veraison) practices deficit irrigation on water relations, yield components quality in a commercial vineyard ‘Crimson Seedless’ table grapes. For this, five treatments were established during complete season (from April to October): (i) Control (CTL) irrigated 110% crop evapotranspiration (ETc); (ii) ...
Root depth is one of the main parameters affecting soil moisture availability held within the plant root zone. This study was conducted to evaluate the trend of corn root development during the growing season in different irrigation methods with two water qualities, and distribution of roots in soil profile. The experiment was a split plot design with three main treatments (subsurface drip(SSD)...
Abstract In arid and semi-arid regions, managing agricultural water for irrigation is essential to cope with scarcity maximize crop yields. this study, an experiment was conducted on a potato in the Manouba region (lower valley of Medjerda, Tunisia). The experimental protocol consisted four treatments utilizing water-saving techniques: FI (Full Irrigation 100%): 100% requirements. DI (Irrigatio...
Nutrient uptake by trees is determined by root interception, soil availability, and tree demand. Fruit trees have low rooting density, especially in the case of dwarfing rootstocks. Mobility in the soil is a key factor in determining nutrient availability, and good management of nutrients requires that supply is matched to demand, in terms of amount, timing and retention in the root-zone, and t...
The use of saline water is a challenge modern agriculture since the this type reduces crop quality and yield. From perspective, study aimed to analyze performance cherry tomato under different levels irrigation salinity partial root-zone irrigation. experiment was conducted in plant nursery at Engineering Agricultural Sciences Campus Federal University Alagoas, Rio Largo, Brazil. experimental d...
Plant roots, with respect to their intrinsic characteristics, have important role in both improvement and development of germplasms of drought resistant plants. This experiment was conducted to study direct and indirect effects of root morphological traits on grain yield of four triticale genotypes (three promising lines of ET-82-8, ET-82-15 and ET-79-17 along with the conventional Junillo-92...
estimation of root-zone salinity using saltmod in the irrigated area of kalaât el andalous (tunisia)
in tunisia, kalâat el andalous irrigated district is one of the most affected areas by salinization. the objective of this study was to predict the root zone salinity (over 10 years) in this area using the saltmod simulation model for subsurface drainage system. saltmod is based on water balance, salt balance model, and seasonal agronomic aspects. in the pilot area, irrigated vegetables crops s...
In a runoff irrigation system using levelled basins, the water uptake patterns of different plant species (Acacia saligna (Labill.) H. L. Wend. and Sorghum bicolor (L.) Moench.) with contrasting root and shoot development were compared. Rainfall amounts during 1995 led to enough runoff water for realizing two cropping cycles. The amount of irrigation water was sufficient to fill the moisture-de...
