Production of grain legumes is severely reduced in salt-affected soils because their ability to form and maintain nitrogen-fixing nodules is impaired by both salinity and sodicity (alkalinity). Genotypes of chickpea, Cicer arietinum, with high nodulation capacity under stress were identified by field screening in a sodic soil in India and subsequently evaluated quantitatively for nitrogen fixat...

Abstract. Declining soil-saturated hydraulic conductivity (Ks) as a result of saline and sodic irrigation water is major cause soil degradation. While it understood that the mechanisms lead to degradation can irreversible changes in Ks, existing models do not account for hysteresis between rehabilitation processes. We develop first model effect on Ks explicitly includes hysteresis. As such, ide...

In India, about 3.77 million ha of the country's geographical area is affected by sodicity. There an urgent need to minimize further land degradation and restore fertility degraded soils meet growing demand for food. The most effective way overcome salt stress applying nutrients through soil foliar. this context, a field experiment was conducted at Anbil Dharmalingam Agricultural College Resear...
