“…Likewise, in peanut [25] found that overall dry weight of weeds decreased by 25.66-25.71% due to reduced irrigation by 60%. Uncontrolled irrigation not only depletes ground water reserves, but may leach nutrients and other chemicals from agricultural lands and this can also allow weeds to grow in irrigated agriculture [26]. Thus, there is a tremendous scope to maintain the productivity with 20-40% less water by eliminating the water loss or weed competition through better crop cultivation.…”

“…Weeds are very dynamic in nature and vary due to differences in soil moisture under different sowing methods. The optimal soil moisture and space may allow weeds to flourish and compete with resources, hence the impact of irrigation on weed growth is a pivotal component of any modern crop production system [26]. It was found that ridges and furrows are the most common method of irrigation worldwide which wets the entire fields and allows water to seep and increase the weed pressure in the irrigated furrows [27].…”

The aim of this study was to explore the effect of sowing methods and deficit irrigation on weed dynamics, yield and water-use efficiency (WUE) of the maize–cowpea system during the summer and monsoon seasons, respectively. The field experiment was carried out for two years (2015 and 2016) using a split design with three replicates under irrigated (maize) and rainfed (cowpea) conditions on vertisols of a semi-arid region. Treatments included three sowing methods [i.e., broad bed and furrow (BBF), corrugated furrow (CF) and ridges and furrow (RF)] and four irrigation levels [i.e., irrigation once in 10 days (I10D), irrigation at 40% (I40), at 50% (I50) and at 60% (I60) depletion]. The results indicated that, regardless of weed flora (monocots, dicots and sedges), the RF method produced higher weed density (2.09–2.98 No. m−2) compared to CF (2.00–2.80 No. m−2) and BBF (1.85–2.64 No. m−2) in maize at 30 and 60 days after sowing (DAS). The RF method with irrigation at I40 and I50 recorded significantly higher weed density, followed by the CF and BBF method. A similar trend was also observed with dry weight of weeds (monocot; 24.19%, dicot; 25.52%, and sedges; 29.80%) in maize at 30 and 60 DAS. Higher weed density and dry weight of weeds in the RF method with I40 was due to higher soil moisture availability and higher nutrient uptake due to larger lateral wetting of the soil and greater water use (29.27%). However, the BBF method favoured the growth of weeds (9.33–16.60%) in cowpea at 55 DAS and coped under rain-fed situation over CF and RF. The CF with moderate depletion (I50) method produced significantly higher maize equivalent yield (MEY) of cowpea (10,000 kg ha−1) with considerable reduction in the total water usage (19.33%). Therefore, under a water scarcity situation, growers can practice CF and I50 for higher yield and WUE of maize–cowpea sequence cropping.

“…Sulama suyu kaynağı ve sulama yöntemi, yabancı ot yoğunluğunu önemli derecede etkilemektedir. Gereksiz su ve gübre uygulamaları da modern tarımda yabancı otların gelişmesine izin vermektedir (Coolong, 2013). Sulama ve sürekli pamuk ekimi ile yabancı ot kontrolü ve bitkisel üretim uygulamalarının, yabancı otların florasının kayması üzerinde etkili olduğunu belirtmekte; çünkü sulama, toprak tuzluluğunu teşvik etmekte ve bu nedenle bu koşulları tercih eden türler daha baskın olabilmektedir (Bükün, 2005).…”

ÖZET iyarbakır'daki pamuk alanlarında yabancı otların mücadelesinde karşılaşılan sorunları değerlendirmek amacıyla 2016'da 80 üreticiye anket uygulanmıştır. Ankette yabancı ot ve herbisitlerle ilgili 16 soru sorulmuştur. Araştırma sonucunda pamuk üreticileri açısından sorun oluşturan yabancı otlar %51 oranında domuz pıtrağı (Xanthium strumarium L.), %22 it üzümü (Solanum nigrum L.), %8 fener otu (Physalis spp.), %5 horozibiği (Amaranthus retroflexus L.) ve %5 kanyaş [Sorghum halepense (L.) Pers.] olarak saptanmıştır. Ankete katılanların %41'i çıkış öncesi total herbisit (%100'ü glyphosate) kullandığını bildirmiştir. Geniş yapraklılar için %94'ünün ekim öncesi (%55'i pendimethalin, %33'ü fluometuron, %5'i benfluralin, %2'si trifluralin (2013'te kullanımı sonlandırılmıştır), %1'i metholachlor-S+benoxacor) ve %6'sının çıkış öncesi fluometuron kullandığı belirlenmiştir. Dar yapraklılar için %88'inin çıkış sonrası herbisit kullandığı saptanmıştır. Herbisit seçiminde %53'ü fiyatın, %17'si yabancı otların, %16'sı yağışın ve sulama yöntemlerinin, %12'si ise münavebe ürününün etkili olduğunu belirtmişlerdir. Mekanik mücadele olarak %73'ünün iki, %24'ünün üç, %3'sının bir defa el+traktör çapası yaptığı belirlenmiştir. Kanyaş ve ayrık gibi rizomlu ve dar yapraklılar çapayla kontrol edilemediğinden, çapalama geniş yapraklılar için yapılmıştır. Ankete katılanların %58'i pamuğun ön bitkisinin pamuk, %30'u mısır ve %12'si buğday olduğunu belirtmiştir. Sonuç olarak pamukta yabancı ot kontrol yöntemlerinin geliştirilmesinin ve ekim öncesi herbisit kullanımına bağlı yapılan uygulamalara alternatif çıkış öncesi ve çıkış sonrası kontrol yöntemlerin geliştirilmesinin önemli olduğu görülmüştür.ABSTRACT survey questionnaire was conducted over 80 cotton farmers in 2016 to evaluate the weed problems in cotton fields of Diyarbakır. The survey included 16 questions on weeds, herbicides, tillage and crop rotation. The research showed that the most common weeds were common cocklebur (Xanthium strumarium L.), black nightshade (Solanum nigrum L.), groundcherry (Physalis spp.), redroot pigweed (Amaranthus retroflexus L.) and johnsongrass [Sorghum halepense (L.) Pers.] were 51, 22, 8, 5, 5% respectively. Only glyphosate used as a total herbicide prior to crop emergence (100%). Across the province, pendimethalin, fluometuron, benfluralin trifluralin (forbidden in 2013), metholachlor-S+benoxacor are used as preplant herbicides to control broadleaf weeds at 55, 33, 5, 2 and 1% respectively.Only fluometuron (6%) was applied as pre-emergence. It was detected that 88% of growers prefered herbicides to control grass weeds. Expense, weed species, rain or irrigation, and crop rotation were considered for herbicide choice by 53, 19, 16, and 12% respectively. Soil tillage during season was applied twice (%78), three times (24%), only once (3%). Since effective control of perennial weeds such as johnsongrass and bermudagrass is not possible by hoeing, the hoeing is made for broadleaf weeds. The preceding crops were cotton (58%), maize (30%) and wheat (12%)....

“…Subsurface drip irrigation has been reported to increase yields and iWUE for processing tomato compared with SUR (Ayars et al, 1999(Ayars et al, , 2015. In addition, SDI may increase nutrient use efficiency (Zotarelli et al, 2008), improve pesticide and fumigant placement in plant beds (Camp, 1998;Lamm and Camp, 2007;Woodrow et al, 2008), and reduce soil surface wetting, thus reducing weed pressure, particularly in arid climates (Coolong, 2013).…”

“…Patel and Rajput (2007) documented a reduction in weed pressure in potato (Solanum tuberosum) with SDI placed at depths as shallow as 10 cm below the soil surface; however, surface wetting and weed pressure were present when SDI was placed at 5-cm depths. Organic vegetable producers are also using shallow SDI to reduce surface wetting, reducing weed pressure, and allowing for cultivation without disturbing drip tubing (Coolong, 2013).…”

Subsurface drip irrigation (SDI) has been increasingly used for the production of numerous agronomic crops and a limited number of vegetable crops. To determine the impact of SDI compared with surface drip irrigation (SUR), a study was conducted in 2011 and 2012 with ‘Table Queen’ acorn squash (Cucurbita pepo var. turbinata) with irrigation initiated at 75% and 50% plant available water (PAW). The study was arranged as a factorial randomized complete block design and plants were grown with two irrigation types (SUR or SDI) and two tensiometer-controlled irrigation regimes. Results from 2011 suggested that SDI used less water compared with SUR at each irrigation set point. However, in 2012, significantly more water was used in all treatments due to warmer temperatures and less rainfall. In 2012, SDI used more water than SUR treatments at the same irrigation set point. In 2012, yield was affected by irrigation treatment. Plants grown using SUR irrigating at 75% PAW had greater numbers of fruit compared with other treatments. Furthermore, the highest yielding treatment had more than twice the number of irrigation events than the other treatments though the average lengths of irrigation events were shorter. Although overall yields were greater in 2012, irrigation water use efficiency (iWUE) was lower than in 2011 due to increased water use. These results suggest that while SDI may have some advantages over traditional SUR, environmental factors during growth can significantly impact the efficiency and productivity of each system.
