Assessing water use by Prosopis invasions and Vachellia karroo trees: Implications for groundwater recovery following alien plant removal in an arid catchment in South Africa

Author: Dzikiti, Sebinasi ; Ntshidi, Zanele ; Le Maitre, David C ; Bugan, Richard DH ; Mazvimavi, D ; Schachtschneider, K ; Jovanovic, Nebojsa ; Pienaar, Harrison H Date: Aug 2017 Prosopis spp., (or Mesquite), is a desert adapted woody weed which has invaded large parts of arid and semi-arid regions. It has a characteristic deep tap root, and forms dense impenetrable thickets along river banks, flood plains, and seasonal ... Read more
Characterising the water use and hydraulic properties of riparian tree invasions: A case study of Populus canescens in South Africa

Author: Ntshidi, Zanele ; Gush, Mark B ; Dzikiti, Sebinasi ; Le Maitre, David C Date: Apr 2018 Invasive alien plants (IAPs) pose a serious threat to the already limited water resources in dry countries like South Africa which are facing increasing water shortages. Much of South Africa is expected to get drier in future due to climate ... Read more
A comparative assessment of water use by Acacia longifolia invasions occurring on hillslopes and riparian zones in the Cape Agulhas region of South Africa

Author: Mkunyana, YP ; Mazvimavi, D ; Dzikiti, Sebinasi ; Ntshidi, Zanele Date: Oct 2018 The detrimental impacts of invasive alien plants on ecosystems and water resources have raised concerns in arid and semi-arid countries like South Africa where the average precipitation is approximately 500 mm/yr, which is below the world ...

Comparison of two remote sensing models for estimating evapotranspiration: algorithm evaluation and application in seasonally arid ecosystems in South Africa

Author: Dzikiti, Sebinasi ; Jovanovic, Nebojsa ; Bugan, Richard DH ; Ramoelo, Abel ; Majozi, Nobuhle P ; Nickless, Alecia ; Cho, Moses A ; Le Maitre, David C ; Ntshidi, Zanele ; Pienaar, Harrison H Date: Sep 2019 Remote sensing tools are becoming increasingly important for providing spatial information on water use by different ecosystems. Despite significant advances in remote sensing based evapotranspiration (ET) models in recent years, important ... Read more
Contrasting water use patterns of two drought adapted native fruit tree species growing on nutrient poor sandy soils in northern KwaZulu-Natal

Author: Dzikiti, Sebinasi ; Ntuli, NR ; Nkosi, NN ; Ntshidi, Zanele ; Ncapai, L ; Gush, MB ; Mostert, THC ; Du Preez, R ; Mobea, NT ; Mpandeli, S ; Pienaar, Harrison H Date: Jul 2022 Natural forests are an important source of livelihood for various communities. Yet economically important fruit tree species endemic to sub Saharan Africa e.g. Sclerocaryea birrea (Marula) are critically endangered due to over-exploitation ... Read more
Deriving crop coefficients for evergreen and deciduous fruit orchards in South Africa using the fraction of vegetation cover and tree height data

Author: Mashabatu, M ; Ntshidi, Zanele ; Dzikiti, S ; Jovanovic, N ; Dube, T ; Taylor, NJ Date: Aug 2023 Inaccurate crop coefficients are major contributing sources of uncertainty that lead to inefficient use of limited available water resources. Understanding the need to improve water use efficiency in South Africa’s fruit industry, this study ... Read more
Effect of different irrigation systems on water use partitioning and plant water relations of apple trees growing on deep sandy soils in the Mediterranean climatic conditions, South Africa

Author: Ntshidi, Zanele ; Dzikiti, S ; Mazvimavi, D ; Mobe, Nompumelelo T Date: Jul 2023 All commercial apple fruit (Malus Domestica (Borkh) exported from semi-arid regions are grown under irrigation with drip and micro sprinkler systems being the most widely used. Few studies have directly compared the physiological responses ... Read more
Estimating crop coefficients for apple orchards with varying canopy cover using measured data from twelve orchards in the Western Cape Province, South Africa

Author: Mobe, Nompumelelo T ; Dzikiti, Sebinasi ; Zirebwa, SF ; Midgley, SJF ; Von Loeper, W ; Mazvimavi, D ; Ntshidi, Zanele ; Jovanovic, Nebojsa Date: Apr 2020 The FAO-56 crop coefficient (Kc) approach is widely used for making irrigation decisions. Allen and Pereira (2009) extended this approach by developing a method for estimating Kc using a density coefficient (Kd), which is estimated from the ... Read more
Estimating the water requirements of high yielding and young apple orchards in the winter rainfall areas of South Africa using a dual source evapotranspiration model

Author: Dzikiti, Sebinasi ; Volschenk, T ; Midgley, SJ ; Lötze, E ; Taylor, NJ ; Gush, Mark B ; Ntshidi, Zanele ; Zirebwa, SF ; Schmeisser, M ; Jarmain, C ; Steyn, WJ ; Pienaar, Harrison H Date: Jun 2018 Exceptionally high yielding (> 100 t ha-(sup1)) apple orchards (Malus domestica Borkh.) are becoming common in South Africa and elsewhere in the world. However, no accurate quantitative information currently exists on the water requirements ... Read more
Water use dynamics of young and mature apple trees planted in South African orchards: a case study of the Golden Delicious and Cripps’ Pink cultivars

Author: Ntshidi, Zanele ; Dzikiti, Sebinasi ; Mazvimavi, D Date: May 2018 Apple orchards have previously been bearing 60–80 t ha-1 at most. However in recent years yield has increased to more than 100 t ha-1. There is need to understand the water requirements of the high yielding orchards, given that high crop loads ... Read more
Water use efficiency of indigenous fruit trees in South Africa

Author: Ntshidi, Zanele ; Mobe, Nompumelelo T ; Dzikiti, S Date: Jul 2022 South Africa is endowed with many indigenous fruit tree species (IFTs). Besides Marula (Sclerocaryea birrea subsp. Caffra), use of indigenous fruit products in the country is generally low compared with other countries on the African continent. ... Read more
Water use of selected cover crop species commonly grown in South African fruit orchards and their response to drought stress

Author: Ntshidi, Zanele ; Dzikiti, Sebinasi ; Mazvimavi, D ; Mobe, Nompumelelo ; Mkunyana, YP Date: Dec 2021 Cover crops are widely planted in orchards for a variety of reasons. These include suppressing soil erosion, nutrient cycling, phytosanitary purposes, general orchard aesthetics etc. However, there is need to balance these benefits against ... Read more
