When fish are recovered from ponds, the effluent is often drained, presenting both an environmental challenge and an agricultural opportunity. The effects of irrigation with pond effluent and its interaction with applied fertilizer were assessed in a field experiment using French bean (Phaseolus vulgaris) and kale (Brassica oleracea) over two growing seasons near Sagana, Kenya. Fresh and dry ma...
When fruit set and rainfall are sufficient, grape yields in Arkansas are high, but rain is not always sufficient in Arkansas. There is enough, in terms of inches, but it often comes at the wrong times. Records during the past 20 years have shown that in all but 3 years in Northwest Arkansas, there have been brief dry spells during the growing season that lasted for at least two or three weeks. ...
As more subsurface drip irrigation (SDI) systems are being installed throughout the plains of Texas for cotton production, irrigators are concerned about the high cost of installation and the potential benefits of alternative designs. A field study was conducted at the Texas AgriLife Research facilities at Halfway, Texas, to document the agronomic impacts of distribution uniformities on cotton ...
Background and Purpose: Water stress is one of the major problems for urban trees. It affects a wide range of plant responses, from changes at the cellular level to the reduction in growth rates. Irrigation of trees in urban areas may provide numerous benefits important for increasing tree vitality to withstand other stresses that might occur. The aim of this study was to compare drought effect...
Canopy temperature is a useful indicator of crop water stress and can also be used for making timely irrigation scheduling decisions for center pivot and subsurface drip irrigation systems. However, it is not known how closely the measured canopy temperature from a circular area of the canopy surface compares with a larger continuous area that includes the full canopy width. A study was conduct...
PROCEDURES: We conducted two studies to investigate an integrated program for root rot (Phytopthora fragriae var. rubi) control in raspberries that would be useful to organic and conventional growers. These two studies have been carried out on our commercial field of ‘Meeker’ that was established in 1997 on raised beds with drip irrigation. Soil at this site is naturally infested with the root ...
Received: July 25, 2017 Revised: November 23, 2017 Accepted: December 17, 2017 Abstract: Introduction: Due to the water shortage and dry Mediterranean condition, determination of water and nitrogen (N) fertilizer requirements is a major challenge for crop production and environment protection. A field experiment was carried out for two consecutive years (2014 and 2015) to evaluate the response ...
