How to reduce irrigated water consumption from already highly strained water resources using the latest in irrigation scheduling software.

With current drought conditions being experienced in the North West, Free State, Kwa-Zulu Natal and Mpumalanga, the South African irrigation farmer is, now more than ever, faced with the problem of “how to produce more, with less”, and to make every drop count.

In order to manage our strained water resources, as well as practice good environmentally sustainable practices, farmers rapidly have to introduce new technologies to improve their efficiencies and yields. In the irrigation farming environment, irrigation scheduling appears to be the most popular and cost effective way to achieve just that.

Irricheck™ is independent of hardware manufacturers, however, prescribe that the most efficient irrigation scheduling hardware in use currently is the continuous logging soil moisture capacitance probe, coupled to a GPRS unit, in order to measure live soil-moisture content and temperature data.

New clementine, satsuma and orange varieties. Growing interest in early and late easy-peeling citrus fruits

www.freshplaza.com

According to David Alba, director of Citrus Genesis, a specialist in integrated development and management of new protected plant varieties, when it comes to citrus fruits, mandarins and clementines are the most common in terms of protected varieties, given current consumer trends, which favour easy-peelers, intense flavour profiles and lack of seeds.

Despite the ongoing focus on citrus black spot, South Africa’s citrus volumes to Europe actually increased significantly in 2015.

The South African citrus industry has been at great pains all season to point out how difficult and expensive it has become for them to trade in Western Europe, due to the measures relating to citrus black spot (CBS) disease they have to contend with.

The Reproductive Phenology of Citrus. II: Citrus floral ontogeny

Jakkie (OPJ) Stander

E-mail: jakkie@sun.ac.za

Citrus trees are perennial evergreens, which sustain a complex tree structure with one to three distinct annual vegetative growth flushes. After a sufficient induction period, with the onset of growth-promoting conditions during spring (increase in temperatures and sufficient water and mineral nutrient supply), flowers develop from buds on vegetative shoots that originated from vegetative shoots in the different growth flushes of the previous 12-month season.

Could Ethylene Metabolism in Lemon Fruit Influence Peteca Incidence?

E-mail: paulcronje@sun.ac.za

Peteca of lemon is a postharvest physiological disorder resulting in the collapse of the oil glands. Subsequently, the oil leaks into the adjacent tissue and
causes a darkened depression. The occurrence can be severe, without any specific pre- or postharvest practises to employ to reduce the incidence.
