investigation of the interrelationships between yield and its components will improve the efficiency of a breeding program with appropriate selection criteria. in this study, the relationship among yield components and their direct and indirect influences on the total yield of melon were investigated. the study was based on evaluation of 49 entries gener-ated from a 7×7 diallel involving irania...

Prolonging the marketing period of peach fruits in Egypt through introducing new cultivars, breaking dormancy early or delaying maturity of some cultivars by safe compounds would increase the growers' profits. This study was conducted during two successive seasons 2005 and 2006 by using "Desert Red" peach cultivar (Prunus persica L.) grafted on Nemaguard rootstock. Trees were grown at El-Noubar...

abstract water is the most common carier used to dilute herbicides and their application. researches had shown that water quality is an important factor in some herbicide efficacy. in order to study the effect of water hardness on 2,4-d efficacy, an experiment was carried out under controlled conditions in 2010 at the college of agriculture, ferdowsi university of mashhad. experimental treatmen...

transport of pathogenic bacteria has been recently considered a major source surface and subsurface water contaminations. soil could affect transport or filtering of bacteria depending on its physical and chemical properties. calcium carbonate and calcium sulfate are two important minerals of arid and semi-arid soils that their effect on bacteria transport has not been investigated, yet. in thi...

In California's Mediterranean climate, management of grapevine trunk diseases (Botryosphaeria dieback, Eutypa Phomopsis Esca) focuses on protecting vines during the dormant season, when pruning coincides with rain-induced spore dispersal causal fungi (‘trunk pathogens’). Applying protectants (fungicides, toxic barriers, sealants, biocontrol agents) after can minimize infection wounds. For seaso...

 Knowledge of the Saxaul dimensions used in sand dunes stabilization is considered essential for designing live windbreak in desert regions. This research aimed to collect and analysis data and was performed on the pruned and control shrubs of Haloxylon aphyllum L. in Yazd province, Iran in the last two decades. Our review clearly showed the superiority of shrubs pruned at the height of 35 cm i...

Two factors of different levels pruning intensities, i.e. 40cm, 60cm and 80cm from ground level, with foliar feeding NAA concentrations, 100ppm, 150ppm 200ppm, were tried to investigate their effects on growth, yield quality attributes phalsa (Grewia asiatica L.)cv. Sharbati, conducted at Horticulture Garden, Department Fruit Science, C.S.A.U.A.T., Kanpur, (U.P). The results showed significant ...
