“…Cabbage is one of the most important cole crops in this region, but it was also classified as intermediately susceptible to water stress (Janes 1950;Singh, Alderfer 1966;Nortje, Henrico 1988). Cabbage production during fall and winter mainly depends on supplemental irrigation.…”

Field experiments were conducted in two seasons to investigate growth, physiology and yield responses of cabbage (Brassica oleracea L. cvs Pennant and Rio Grande) to deficit irrigation. In 2012 season, 50% of crop evapotranspiration (ETc) irrigation temporarily decreased plant size, reduced leaf area, fresh weight, relative water content, specific leaf area and gas exchange during late development, and decreased head fresh weight, size, marketable and total yield. Deficit irrigation at 75% ETc had little influence on plant growth and physiology, but it still reduced both marketable and total yield. In 2013 season, 75% ETc irrigation had little influence on plant growth, leaf characteristics, photosynthetic rate, head fresh weight and size, but it temporarily increased chlorophyll and carotenoid content, and decreased stomata conductance, transpiration, and marketable yield. Pennant, the green-head cultivar, had higher photosynthetic rate, head fresh weight, marketable and total yield than the red-head cultivar Rio Grande. In both seasons, deficit irrigations did not influence cabbage head dry weight, indicating that most yield reduction under deficit irrigations is related to water content.

“…Under furrow method, water was supplied to all furrows at every irrigation cycle thus, maximum bulbs survived at the end of growing season. In alternate and fixed furrow methods where water was supplied to specific furrows (leaving others dry), induced water stress may have resulted in fewer bulbs per hectare as reported by Singh and Alderfer (1966). Contrary to alternate furrow, (where soil moisture in furrows refilled due to shuffling after each cycle) in fixed furrow method specific furrows remained dry throughout the growing season thus caused greater plant mortality rate which ultimately reduced number of bulbs per hectare.…”

“…Scientists reported improved crop water productivity by the use of regulated deficit irrigation (English, 1990;Goodwin and Jerie, 1992;Pereira et al, 2002;Fereres and Soriano, 2007) partial root zone drying (Kang et al, 1997(Kang et al, , 1998(Kang et al, , 2000a(Kang et al, , 2002bKang and Zhang, 2004;Zegbe et al, 2004) or alternative furrow irrigation (Mitchell et al, 1993;Mitchell and Yang, 1998). Due to shallow root system (Shock et al, 1998), absence of root hairs and lower leaf water potential (Brewster, 2008) onion is considered very sensitive to water stress (Singh and Alderfer, 1966). Onion crop showed significant reduction when subjected to deficit irrigation (Al-Jamal et al, 2001;Shock et al, 1998).…”

Onion is highly sensitive to water stress due to the absence of root hairs and shallow root system. Water stress at any growth stage of onion can result in severe loss of yield and profit. Moreover, fresh water availability for irrigation is continuously declining due to population explosion and global warming. There is a dire need to increase water productivity of irrigation systems. Although drip irrigation is highly efficient, its practical application is limited in developing countries due to high installation costs and lack of technical knowledge among farmers. The present research work was conducted in semiarid climate of Faisalabad, Pakistan to examine low cost irrigation methods for their profitability for onion production even under limited water availability. A field study was conducted using two onion cultivars (Dark red and Robina) with and without mulch under three irrigation methods (furrow, fixed furrow and alternate furrow) during two consecutive winter seasons (2012-13 and 2013-14). Results showed that profitability of onion bulbs produced under alternate furrow irrigation method with mulching was at par with bulbs produced by furrow irrigation without mulching (common method used by farmers). Among onion cultivars "Dark red" was found more consistent in generating a profit under limited water supply than "Robina". From the experimental results it may be concluded that under limited supply alternate furrow irrigation can be successfully used as an effective low cost substitute of normal furrow irrigation. The results showed that profitability of alternate furrow may be enhanced by the application of mulching.

“…Thus, adjustments to irrigation practices during broccoli heading may provide some control for disease. Irrigation also must be adequate during head initiation and enlargement for satisfactory yields of broccoli (17). Better management of bacterial soft rot in Oregon requires more specific knowledge of irrigation effects on disease development and yield.…”

Effect of Sprinkler Irrigation on Bacterial Soft Rot and Yield of Broccoli

The effect of amount of applied water under two irrigation frequencies (once versus three times per week) on the incidence of bacterial soft rot, caused by Erwinia carotovora subsp. carotovora, and yield of broccoli was investigated in field studies conducted in 1987 and 1988. At head initiation, the amount of applied water was varied by utilizing a line source irrigation system. Incidence of soft rot was higher in the OSU breeding line 86-3 plots, followed by cv. Citation and then cv. Gem. Soft rot was not consistently affected by amount of applied water. Differences in amount of disease were apparent, however, between the separate irrigation frequency studies in 1988; disease incidence more than doubled under the high- compared with the low-frequency irrigation. Further studies on the effects of frequency and timing of sprinkler irrigation on soft rot and yield of Gem broccoli were undertaken in 1993 and 1994. Six sprinkler irrigation regimes, a factorial combination of frequency (irrigation every 2, 4, or 8 days) and timing (morning or evening), were established. Total water applied did not differ by treatment. Incidence of soft rot was negligible at the first harvest in both years. At the last harvest, the incidence of soft rot was significantly reduced, from 22 to 10% in 1993 and from 30 to 15% in 1994, by the change in frequency of irrigation from 2 to 8 days. In contrast, timing of irrigation had no effect on disease incidence. Yield of broccoli was not affected by either frequency or timing of irrigation.
