The effect of sodium silicate on yield and yield components of pea (Cicer arietinum L.) under salinity stress

Peas are the second most important plant families with high quality protein and important role in increasing soil nitrogen. The plant is sensitive to salinity and given that a large part of our land and the passion necessary to make possible the necessary measures to be taken to prevent a decrease in performance. In this regard, one of the elements that can improve plant water status, the effects of salinity amend, is silicon. For this purpose, a factorial experiment in a completely randomized design with three replications was conducted. Treatments consisted of soil salinity at levels 2, 4 and 6 dS/m and sodium with levels of 0, 1 and 2 mM. The results showed that salinity had a significant effect on the number of pods per square meter, number of seeds per square meter, grain weight, grain yield and dry matter, so that increasing salinity level would be to reduce the amount of these traits. The yield on the EC 6 dS.m to the 41.4 grams per square meter, respectively. Silicon is also a significant effect on the number of pods per square meter, seed weight and seed yield. The highest grain yield in 2 mM sodium consumption to the amount of 99.7 grams per square meter.
