The severity of drought during the Maya collapse

The severity of drought conditions throughout the dying of the Maya civilization regarding one,000 years agone has been quantified, representing another piece of proof that would be wont to solve the long mystery of what caused the downfall of 1 of the traditional world’s nice civilizations. [1]

TEST OF COTTON LINES WITH DROUGHT TOLERANT INTERCROPPED WITH MAIZE

The distribution of cotton cultivation is usually settled within the sub-optimal land because of competition with the sphere crop. The cotton cultivation in the state is often done through intercropping with pulses. This analysis aims to check the suitableness of cotton lines with drought-tolerant intercropped with maize. The analysis is conducted in February to August 2016 at Asembagus Experimental Garden, Situbondo. [2]

Evaluation of Physiological and Agronomic Characteristics Related to Drought Tolerance in Spring Rapeseed

Introduction: Among the various environmental stresses, the drought could be a major limitation in reducing crop yields. oilseed could be a plant all-mains to areas with restricted downfall throughout winter and spring and dry air at flowering, grain filling and maturity stages. Water deficit stress throughout the pod filling stage in oilseed reduces the number of grains per money supply, oil p.c, and grain yield. Positive and vital correlations were reported among grain yield with pod variety per plant and grain number in an exceeding pod in winter genotypes of canola, beneath traditional and drought stress conditions. the robust negative relationship between grain yield and cover temperature throughout the procreative stage of colza L. genotypes are reported. The results of learning oilseed genotypes beneath drought stress indicated that the chlorophyll and b content of all genotypes declined because of drought stress at flowering and grain filling stages, however larger reduction in grain yield was discovered once stress was obligatory at flowering stage.

Effects of Drought Stress on Canola (Brassica napus L.) Genotypes Yield and Yield Components

Introduction: Canola (Brassica napus L.) genotypes with the wide ability to environmental conditions might play a serious role in Iran’s seed crop production. choice of high playacting genotypes is extremely necessary for developing canola cultivation. Water stress will cut back crop yield by poignant each supply and sink for assimilation. Canola yield depends on genotype and environmental conditions and response of genotypes to environmental factors. Canola genotypes response to worry depends on the biological process stage and therefore the events occurring before and through the flowering stage. Resistance to water stress is split into turning away and tolerance. Some species square measure tolerable against water stress. [4]

Impact of Drought on Chlorophyll, Soluble Protein, Abscisic Acid, Yield and Quality Characters of Contrasting Genotypes of Tomato (Solanum lycopersicum)

Impact of drought stress on pigment, pigment visible radiation (Fv/Fm), pigment stability index (CSI), soluble macromolecule, abscisic acid (ABA), yield and quality of tomato (Solanum lycopersicum) genotypes was investigated for the assessment of drought tolerance beneath field conditions in rainout shelter. The drought condition was created initial day from movement supported Irrigation water (IW):Cumulative Pan Evaporation (CPE) of soil. Experiment was ordered out with ten genotypes by adopting FRBD with 3 replications and 2 treatments of one IW:CPE and zero.5 IW:CPE. The result disclosed that the reductions in pigment content, Fv/Fm, pigment stability index (CSI), soluble macromolecule and yield were detected at drought condition (0.5 IW/CPE). [5]
