The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot provided opportunity to assess if single in-season measurements had value in evaluating at-harvest damage to bolls and if multiple in-season measurements enhanced their combined use. One in-seaso...

Investigating the crop response to the deficit irrigation and evaluating the effect of drought stress on plant is one of the most important issues in crop production. In these circumstances, the use of organic fertilizers can play a mitigative role. Hence, an experiment was laid out as split plot based on randomized complete blocks design with three replications in Research Farm of University o...

Salinity is one of a major abiotic stress, specifically on arid and semi-arid areas that has influenced on crop growth and reduced grain yield. The purpose of present study was identification of agronomic traits related to wheat grain yield variation under control and salinity conditions. In order to produce a population of 272 recombinant inbred lines (RILs), a cross between two bread wheat cu...
