RESPONSE OF WHEAT CROP TO NITROGEN SOURCES AND APPLICATION TIMES UNDER SALINE SODIC SOIL CONDITIONS

Reclamation of Saline-sodic Soils under Rice-wheat Crop Rotation

A field experiment on a saline-sodic soil with pH 8.21-8.42, ECe 6.40-7.90 dSm and SAR 17.79-23.46mmolwas carried out using five soil reclaiming treatments viz., leaching (Control), Farm yard manure (FYM) @ 10 tons ha, Rice Husk (RH) @ 10 tons ha, FYM+RH @ 5+5 tons ha and Gypsum @ 100% soil requirement in a complete randomized block design with four replications. Rice variety SARSHAR and wheat ...

Saline/Sodic sub-soil on triticale, durum wheat and bread wheat yield under irrigated conditions

Sub-soil (> 30 cm) salinity and sodicity is a growing problem particularly in irrigated agricultural areas with rising water tables, poor water quality and/or deficient soil drainage. There were two objectives in this study; (1) to quantify the effect of sub-soil salinity and sodicity in grain yield of triticale, bread wheat and durum wheat and, (2) to determine if genotypes within and between ...

Physiological Response of Quinoa to Nitrogen Application under Salinity Conditions

Salinity stress is one of the major abiotic stresses which injures plants by limited water absorption and nutrient imbalance and limits crop growth. In order to study the effect of nitrogen fertilizer on physiological traits of quinoa at high salt concentrations, a greenhouse experiment was conducted in a factorial arrangement based on a randomized complete block with three replications in 2019...

Response of wheat crop during transition to organic system under Mediterranean conditions

Organic agriculture is an ecological production management system aimed at sustainableproduction of safe food, environmental protection and maintenance of soil health. The objectiveof this study was to evaluate, in a period of organic transition, the effects of different organicfertilizers on wheat yield, grain quality and soil characteristics. The research was performedin an experimental farm ...
