Abstract Drought susceptibility and low genetic variability are the major constraints of lentil (Lens culinaris Medik.) production worldwide. Development of an efficient pre-field drought phenotyping technique and identification of diversified drought tolerant lentil genotype(s) are therefore vital and necessary. Two separate experiments were conducted using thirty diverse lentil genotypes to isolate drought tolerant genotype(s) as well as to assess their diversity. In both of the experiments, significant (p ≤ 0.01) variation in genotype (G), treatment (T) and G X T was observed for most of the studied traits. In experiment I, genotypes were examined for drought tolerance at… More >

Abstract Water is essential for the growth period of crops; however, water unavailability badly affects the growth and physiological attributes of crops, which considerably reduced the yield and yield components in crops. Therefore, a pot experiment was conducted to investigate the effect of foliar phosphorus (P) on morphological, gas exchange, biochemical traits, and phosphorus use efficiency (PUE) of maize (Zea mays L.) hybrids grown under normal as well as water deficit situations at the Department of Agronomy, University of Agriculture Faisalabad, Pakistan in 2014. Two different treatments (control and P @ 8 kg ha⁻¹ ) and four hybrids… More >

Abstract Drought can limit the growth and reduce the yield of crops, but the safe and effective bio-approach to improve the drought resistance of crops is very little. We conducted an experiment in which we monitored the effects of polysaccharide from the endophyte Bionectria sp. Fat6 on the growth of Tartary buckwheat (Fagopyrum tataricum (L.) Gaertn) seedlings under control and drought-stressed conditions by determining gas exchange, photosynthesis parameters, photosynthetic pigment contents, and metabolite accumulation. Results indicated that the polysaccharide from endophyte stimulated plant growth and increased the aboveground biomass, root mass, and root/shoot ratio of Tartary buckwheat. Application… More >

Abstract Drought is one of the major abiotic stresses that affect plant growth and reduce agricultural productivity. Use of algal extract as a biostimulant is gaining increased attention from researchers. This study aimed to investigate the potential of Ulva prolifera extract (UE) as a biostimulant when enzymatically extracted under conditions of water deficit. UE treatments (0.02%, 0.06%, and 0.1%) significantly improved the shoot length, root length, and dry weight of roots after 120 h of drought stress relative to that in treatment with the negative control. An increase in catalase (CAT) and peroxidase (POD) activity was also More >

Abstract Application of biochar to agricultural soils is mostly used to improve soil fertility. Experimental treatments were comprised of two factors: i) drought at two level, i.e., 80% and 40% water holding capacity (WHC) which was maintained on gravimetric basis ii) three levels of biochar i.e., control, 2 t ha^-1 and 4 t ha^-1 added to soil. Experimentation was done to examine potential of biochar application to enhance the growth attributes, water relations, photosynthetic pigments and antioxidants activities in maize (Zea mays L.) seedlings. Results of study revealed that biochar application increased the growth qualities (total seedlings biomass,… More >

Abstract Two experiments were performed in 2011-2012 to investigate the response of three oilseed rape cultivars to drought stress, grown under two climate conditions in Iran (cold and hot climates). The experiments were conducted using a randomized complete-block design arranged in split-plot with three replicates. The irrigation treatments (FI: full irrigation; WIF: withholding irrigation at flowering stage, and WIS: withholding irrigation at the silique formation stage until physiological maturity) were allocated to main plots, whereas subplots consisted of the oilseed rape cultivars: early maturating (GKH2005), relatively late maturing (Opera) and late maturing (Okapi). Drought caused a… More >

Abstract Understanding the genetic control of traits associated with yield helps breeders to utilize their germplasm in a more efficient and consistent manner and to make good choices in breeding programs. The current study was carried out to study the genetic control of some quantitative traits in bread wheat (Triticum aestivum L.) and to examine plant responses under full irrigation and drought stress conditions. For this purpose, six generations derived from a cross between two lines (Bezostaya as tolerant parent and 518 as a susceptible parent) were evaluated for grain yield (GY), plant height (PH), peduncle (PL)… More >
