Diversity in Betasatellites Associated with Cotton Leaf Curl Disease During Source-To-Sink Movement Through a Resistant Host
Cotton leaf curl is devastating disease of cotton characterized by leaf curling, vein darkening and enations. The disease symptoms are induced by DNA satellite known as Cotton leaf curl Multan betasatellite (CLCuMuB), ...
Zinc Deficiency in Rainfed Wheat in Pakistan: Magnitude, Spatial Variability, Management, and Plant Analysis Diagnostic Norms
Zinc (Zn) deficiency is a widespread micronutrient disorder in crops grown in calcareous soils; therefore, we conducted a nutrient indexing of farmer-grown rainfed wheat ( Triticum aestivum , cv. Pak-81) in 1.82 Mha Potohar ...
Food Security and Water Poverty in Central and West Asia and North Africa Region
ll countries in Central and West Asia and North Africa (CWANA) region in general, and the WANA region in particular, have faced severe challenges in increasing their agricultural production over the last 40 years. This is ...
Laser-land leveling adoption and its impact on water use, crop yields and household income: Empirical evidence from the rice-wheat system of Pakistan Punjab
Using a primary dataset from 350 farmers from the rice-wheat area of Pakistan Punjab, we estimate the impact of laser-land leveling on water saving, crop yields and household income. The analysis employs propensity score ...
Effects of genetic changes to the begomovirus/betasatellite complex causing cotton leaf curl disease in South Asia post-resistance breaking
Cotton leaf curl disease (CLCuD) has been a problem for cotton production across Pakistan and north-eastern India since the early 1990s. The appearance of the disease has been attributed to the introduction, and near ...
First Report of Chilli leaf curl virus and Associated Alpha- and Beta-satellite DNAs Infecting Nettle Weed (Urtica dioica) in Pakistan
Weeds act as reservoirs of begomoviruses and ‘‘mixing vessels’’ leading to emergence of new viruses that may infect crops once a susceptible host plant is introduced into an agro-ecological system. Owing to the importance ...
Productivity enhancement of salt-affected environments through crop diversification
Recent trends and future demographic projections suggest that the need to produce more food and fibre will necessitate effective utilization of salt-affected land and saline water resources. Currently at least 20 per cent ...
Marketing of goat and sheep skins in highland Balochistan, Pakistan
This study investigated the market of skins of small ruminants through interviews with market agents in highland Balochistan. Two major factors affected skin prices: seasonality and animal species. Prices for sheep and ...
Improved water-management practices and their impact on food security and poverty: empirical evidence from rural Pakistan
Using a comprehensive data set collected through field survey of 950 farmers across Pakistan, the current study evaluates water-management practices and their impact on food security and poverty. The results show that rural ...
A SWAT modeling approach to assess the impact of climate change on consumptive water use in Lower Chenab Canal area of Indus basin
Accurate assessment of spatio-temporal variations of consumptive water use (CWU) in large
irrigation schemes is crucial for several hydrological applications. This study is designed to evaluate
the impact of climate change ...
