Plants in their natural habitats adapt to drought stress in the environment through a variety of mechanisms, ranging from transient responses to low soil moisture to major survival mechanisms of escape by early flowering in absence of seasonal rainfall. However, crop plants selected by humans to yield products such as grain, vegetable, or fruit in favorable environments with high inputs of wate...

Economic weights have been estimated in two breeds (Latxa and Manchega) using economic and technical data collected in 41 Latxa and 12 Manchega dairy sheep flocks. The traits considered were fertility (lambing per year), prolificacy (number of lambs), milk yield (litres) and longevity (as productive life, in years). A linear function was used, relating these traits to the different costs in the...

Debate over the consequences of marine reserve implementation has long focused on tradeoffs between ecological improvements from reserves and possible economic losses from reduced harvest. More recently, several articles suggest instead that reserves might generate economic as well as ecological benefits (1; 2; 3; 4). In particular Hastings and Botsford demonstrate that, even without any ecolog...

A field experiment was carried out in 2020 kharif season, on loamy sand soil at the S.K.N. College of Agriculture's Agronomy Farm Jobner (Rajasthan). It included two foliar sprays each four liquid manures (control, 100% RDP panchgavya @ 5%, vermiwash 10%, and cow urine 5%), totaling sixteen treatment combinations. treatments organic through FYM, vermicompost, poultry manure) manures. Three repl...

In order to investigate the effect of urea and Azocompost on economic yield, nitrogen use efficiency (NUE) and radiation use efficiency (RUE) of wild majoram, a factorial experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 k...

The objective of present study was to derive the economic values for number of inseminations to conception, calving interval, milk yield and stillbirth, using economic data of 10 Iranian Holstein herds. The economic values were derived by using the profit function methods and differentiating a profit equation with respect to the traits of interest. The cow fertility costs herd amortization or r...

this study investigated the effects of land size and two leased and private farming systems of machinery on economic efficiency and factors such as total production cost per hectare (ratio of total cost of agricultural inputs and operations to farm size), total income (ratio of product and byproduct value to farm size), yield (ratio of crop production to farm size) and degree of mechanization f...
