Abstract:

In this study, seventy two sunflower recombinant inbred lines were tested for their yielding ability under both water-stressed and well-watered states. The inbred lines were evaluated in a rectangular 8?9 lattice design with two replications in both well-watered and water-stressed conditions, separately. Eight drought tolerance indices including stability tolerance index (STI), mean productivity (MP), geometric mean productivity (GMP), harmonic mean (HM), stress susceptibility index (SSI), tolerance index (TOL), yield index (YI) and yield stability index (YSI) were calculated based on grain yi

Abstract:

The aim of this study was to test the behavior of 5 genotypes cultivated in normal and irrigated conditions with regard to drought stress. We used seven indices of tolerance and resistance to drought stress. Analyze of variance showed that the geometric mean productivity, mean productivity, stress tolerance index, yield stability index, stress sensitivity tolerance and tolerance intensity were effective in judging tolerance to water stress, Boussellem and Oum Rabie was the best at water stress resistance genotypes. Correlation analysis showed that GMP is both an indicator of high performance u

Abstract:

Abstract Most of investigations showed that nitrogen fertilizers gave substantial rapeseed yield increases even in diverse and contradicting conditions but in a few studies were focused on nitrogen deficiency stress effects. Some of important seed yield stress indices based on application and non application of nitrogen (N+ and N0) was studied using six spring rapeseed varieties and their 15 F2 progenies. Significant mean squares of genotypes effects were observed for potential yield (Yp), stress yield (Ys), mean productivity (MP), geometric mean productivity (GMP), tolerance index (TOL), stre

Abstract:

Given the current scenario of global climate change, high temperature stress is appearing as a major challenge limiting crop productivity including chickpea (Cicer arietinum L.). Evidences of significant yield loss in chickpea due to high temperature stress encountering during reproductive stage has been recorded. Therefore, to sustain chickpea productivity, identification of heat stress (HS) tolerant chickpea via recruiting ‘breeder’s friendly’ selection criteria based on yield traits under field condition is urgently needed. In our current study, we evaluated 78 chickpea genotypes (including

Abstract:

Durum wheat (Triticum durum L.) is used for the preparation of multiple food products, including pasta and bread. Its production is restricted due to diverse environmental stresses i.e. drought and heat stress. Here, comparative analysis of durum wheat varieties was done by studying canopy temperature depression (CTD) and chlorophyll content (CHL), yield and yield contributing traits to evaluate their performance under stress and low stress conditions. Twelve durum wheat genotypes were studied under stressful and low-stress conditions in Gachsaran region of Iran. CTD and CHL were measured at t

Barley is widely cultivated in the northern coasts of Egypt and in the newly reclaimed lands. The goal of this study was response of some naked barley cultivars with high yield potential using supplemental irrigation under rain-fed conditions at Al-Kasr area, Marsa Matrouh, North-Western Coast of Egypt. The growth, yield, and drought-tolerance indices of Giza 129, Giza 130, and Giza 131, barley cultivars were estimated under rain-fed and supplemental irrigation regimes (SI0: rainfall only; SI1: two supplementally irrigations at tillering and heading stages; SI2: three supplementally irrigation

Subsequently, an applied treatment was conducted over the past decade at the infertile Salmon River to offset intensive logging impacts and to accelerate colonization of steelhead tro

Abstract:

Desertification is one of the major problems affecting our environment in the 21st century. Indeed, it threatens more than 1.5 million people worldwide and affects a quarter of the land in less than 100 countries, it spreads over half a billion hectares per year and reduces the surface water and groundwater. Thus, according to a report by the Food and Agriculture Organisation written in 1993, the direct and visible impacts of desertification are the damage on crops, on livestock, on the electricity productivity, etc. Indirect impacts are lack of food production, poverty, social upheaval, rural

Abstract:

Abstract Since early 2010s’, horizontal drilling has become the standard practice in developing oil and gas production capacities – it amounts for over 80% of production capacities in USA alone. However, despite countless improvements in technology, many operators are seeking additional insights into explored reservoirs, as lateral wellbores pose numerous challenges, especially when introducing water. Horizontal wells have a larger contact area with the reservoir compared to vertical wells, which means they are more likely to encounter water-bearing zones. This can happen if the well is drille
