We investigated the role of Azospirillum brasilense and trans-zeatin riboside (tZR) in the mitigation of arsenic toxicity in wheat for 2 years (2018–2019 and 2019–2020) in pot experiments. Wheat plants grown in soil artificially spiked with arsenic (50, 70, and 100 μM) was left alone or amended with A. brasilense, tZR, or their combination as mitigation strategies. A treatment without arsenic or amendments was maintained as control. Arsenic-induced physiological damages were noticed in the wheat plants. Detrimental effects on the plant physiological functions, such as disruption of cell membrane stability, reduced water uptake, and stomatal functions, were noticed with increase in As toxicity. Application of biological amendments reversed the effects of As toxicity by increasing wheat plant growth rate, leaf area, and photosynthesis and also yield. The...

Three mulch treatments (M0 = no mulch, M1= black plastic mulch and M2= straw mulch) and three irrigation levels (I0= 5days interval, I1= 10 days interval and I2= 15 days interval) were used in the experiment. Minimum weeds number and biomass was recorded under black plastic mulch, followed by wheat straw mulch and maximum in control (without mulch) treatment. Water related parameters like relative water content, excised leaf water loss, soil moisture percentage and yield related parameters like number of bolls, 100 bolls weight, seed cotton yield, biological yield, harvest index and water use efficiency were higher under combination of black plastic mulch with irrigation interval of five days. It was concluded th...

Many advances regarding role of zinc under abiotic stress in plants have been made since its revelation, therefore, present study was intended to understand the ameliorating role of zinc on morpho-physiological and biochemical responses of the okra varieties (Anmol and Haseena) when exposed to salt stress. A solution culture experiment was conducted to understand the protective role of zinc in relation to growth, physiological, ionic and antioxidant attributes in two okra varieties under saline condition. The growth medium was salinized with three salinity (Control, 80 mM L−1 and 160 mM L−1 NaCl) and one zinc level (30 µM L−1) applied exogenously in combine and sole form. Salt stress significantly reduces plant dry matter accumulation, chlorophyll contents, relative water contents (RWC), membrane stability index (MSI), K+/Na+ ratio and ac...

Daryanto et al. (2016) estimated that in the next 20 years, wheat production has to increase up to 60% to meet market demand. Water deficit stress is a major abiotic stress in the world especially in dry climates. Water deficit condition decreased plant growth and actual grain yield (Raza et al., 2012a). Limited water availability for the plant negatively effect on plant water relationship that alters the phenotypic and physiological processes(Raza et al., 2015). Limited crop growth under drought is reported by different scientists (Raza et al., 2014, Daryanto et al., 2016; Jamshaid et al., 2018). Parameters reduced by drought include leaf water content, chlorophyll contents, 1000-grain weight and grain yield (Daryanto et al., 2016), rate of photosynthesis (Niakan and Ahmadi, 2014) as well as soluble sugar contents (Nohong and Nompo, 2015). Drought stress influences internal phytohormone concent...

The objective of the study was to investigate the role of biochar for the improvement of wheat (Triticum aestivum L.) growth and soil biochemical properties under drought conditions. A pot experiment with a completely randomized design was arranged with four replications in a wire house. Drought was imposed on two critical growth stages (tillering and grain filling) and biochar was applied to the soil 10 days before sowing at two different rates (28 g kg−1 and 38 g kg−1). Soil samples were collected to determine the soil properties including soil respiration and enzymatic parameters after crop harvesting. Results showed that water stress negatively affects all biochemical properties of the soil, while biochar amendments positively improved these properties. Application of biochar at 38 g kg−1 provided significantly higher mineral nutrients, Bray P (18.72%), exc...

Therefore, new eco-friendly agricultural practices for sustainable food production are needed. Mulching could potentially serve the purpose by reducing soil evaporation, conserving moisture, controlling soil temperature, reducing weed growth, and improving microbial activities. Additionally, mulches could provide economical, aesthetic, and environmental advantages to agriculture and landscape. Moreover, in the restoration sites, mulches are widely used for the plantation of trees which need no significant care. Mulches combat with different stress conditions in agricultural lands as well as in landscapes. This review paper focuses on multiple significant impacts of mulches for the production and establishment of different crops in nature. Mulches conserve the soil moisture, enhance the nutrients status of soil,...

There is a growing requirement for more use of our natural resources of land, soil, and water. There is ever-increasing pressure on water resources for our extensive use in agricultural production. There needs to be innovative solutions for more efficient irrigation techniques for better development of agricultural irrigation management. Main body of the abstract This review paper shows the consequences of partial root-zone drying happening on various plant species, its advantages and disadvantages, and also the hormone production under partial root-zone drying. In this technique of irrigation, a wet-dry cycle irrigates the crop, i.e., irrigation is scheduled at a regular interval with half way root drying. Short conclusion This is a water-saving irrigation strategy used in arid and semi-arid environments for increasing irrigation water use efficiency and...

To fulfill the dietary needs of increasing population with depleting water resources there is need to adopt technologies which result in sufficient crop yield with less water consumption. One of them is partial root zone drying (PRD). Keeping in view these conditions, a wire house experiment was conducted at University College of Agriculture and Environmental Sciences, The Islamia University Bahawalpur during 2015, to screen out the different wheat genotypes for PRD. Five approved local wheat cultivars (V1= Galaxy-2013, V2= Punjab-2011, V3 = Faisalabad-2008, V4 = Lasani-2008 and V5 = V.8200) and two irrigation levels (I1 = control irrigation and I2 = PRD irrigation) with completely randomized design having four replications were used in the experiment. Among the varieties Galaxy-2013 performed the best and attained maximum plant height, leaf area, stomatal conductance, photosynthesis...
