“…Generally, the cotton yield is largely dependent on its height as higher plant develops more nodes, branches and leaves that are the main sites for photosynthesis (Ahmad et al, 2015). A lower plant height under PRD irrigation is probably due to less cell division and turgidity (Raza et al, 2017). Stikic et al (2003) also recorded a lower plant height under PRD irrigation than under full irrigation.…”

“…Leaf area index (LAI, m 2 /m 2 ) was measured with portable laser leaf area meter (CI-2002L, CID Bio Science, United States). Leaf relative chlorophyll content (%) was measured by chlorophyll meter (CL-01, Hansatech instruments Ltd., United Kingdom) (Raza et al, 2017). To calculate the leaf relative water content (LRWC, %), we sampled the youngest fully expanded leaves and recorded their fresh weight (FW, g) and soaked the leaves for 24 h at 25°C in distilled water, after which turgid weight (TW, g) was recorded.…”

“…Net photosynthesis rate (µmol/(m 2 •s)) and stomatal conductance (mmol/(m 2 •s)) of cotton leaves under natural conditions (Raza et al, 2017) were measured with, respectively, an infrared gas analyzer (Li-COR-LI 6250, Hertford, Herts, England) and an automatic porometer (MK-3, Delta-T Devices, Burwell Cambridge, England).…”

“…Maintenance of turgor and production of antioxidant enzyme activities are helpful in reducing the damaging causes of drought. Enzymes mostly involved in this defense mechanism are catalase (CAT), superoxide dismutase (SOD), peroxidase (POD) and ascorbate peroxidase (APX) (Raza et al, 2017). Previous studies revealed that activities of these enzymes significantly increased under PRD irrigation (Javanovic and Stikic, 2018), thus reducing the harmful effects of drought in cotton (Ullah et al, 2017).…”

Water is the main factor for the healthy life of plant. One of the main negative effects of climate change is the increasing scarcity of water that is lethal for plant. Globally, for water deficit regions (arid and semi-arid), drought is the main factor responsible for low production of agriculture, especially for cotton. Great efforts have been and are being made to find alternatives to water saving practices. This study aimed to examine the effects of partial rhizosphere drying (PRD, half of the root system irrigated at one event, and the other half irrigated in the next event, and so on) with and/or without various mulching treatments on physiological and biochemical traits of cotton. To explore this objective, we laid out experiments in completely randomized design with factorial arrangement in the Islamia University of Bahawalpur, Pakistan in 2016. Two factors included were four mulching treatments (M 0 , no mulching; M 1 , black plastic mulching; M 2 , wheat straw mulching; and M 3 , cotton sticks mulching) and two irrigation levels (I 0 , control (full irrigation); and I 1 , PRD). Fisher's analysis of variance among means of treatments was compared using least significant difference test at 5% probability level. Results revealed that the maximum plant height, leaf area, leaf gas exchange (photosynthetic rate and stomata conductance), chlorophyll, proline and total sugar contents, and enzyme activities were higher under M 2 than under other three mulching treatments. As for irrigation levels, higher values of plant height, photosynthesis and water related parameters (leaf water potential, leaf osmotic potential, leaf turgor potential, etc.) were recorded. Contents of total sugar and proline and activities of antioxidant enzymes were significantly higher in PRD-treated plants than in control plants. It was concluded that combined application of PRD and mulching was more effective than the rest of the treatments used in the experiment. Similar study can be conducted in the field by applying irrigation water in alternate rows in semi-arid regions.

“…PRD induced production of abscisic acid (ABA) by plant roots minimize stomatal conductance, minimize transpirational water loss and make plant more water efficient. Hence increase water use efficiency (Raza et al, 2017). It was first used by Grimes et al (1968) in cotton and reported 32% water saving with 5% yield loss.…”

Significance of Partial Root Zone Drying and Mulches for Water Saving and Weed Suppression in Wheat

One of the main negative effects of climate change is the increasing scarcity of water worldwide. Wheat is the second major staple food of the world and drought is the main factor affecting its production. In order to ensure food security, there is need to adopt easy and economic techniques for increasing crop production under limited water resources. Two of the effective techniques are; use of ground covers and partial root zone drying (PRD). Experiments were comprised of two irrigation methods (I 1 = irrigation on both sides of roots and I 2 = irrigation to only one side of root as alternate irrigation) and four ground covers (M 0 = open ground without any cover, M 1 = black plastic cover, M 2 = wheat straw cover and M 4 = cotton sticks cover). Results revealed that more spike length, number of spikelets and grains were found in full irrigation treatment. While water use efficiency and grain nutrient (NPK) contents were more in PRD. All soil covers suppress the weeds and significantly influenced the yield attributes as well as the grain nutrient contents. However, black plastic cover performed the best. It was concluded that joint use of both techniques was more effective than their sole application and combination of PRD with black plastic mulch performed the best than rest of the treatments.
