تأثير الملوحة في بعض صفات النمو الخضزي والحاصل لصنفين من الذرة البيضاء Sorghum bio –color. (L.)Moench

Abstract

An experiment was made in a special field on the bank of AL-Diwaniyah River to study the effect of the different salinities concentration from NaCl and CasO4 on some growth parameters productivity for two varieties from Sorghum bio-color (Ingath and Milo).The ground was divided into six equal sheets and two factors were used for each. The randomized complete blocks were used L.S.D at 0.05 was used as a method to compare means separation treatment effect was evident. The study involved: the leaf area, the plant height, dry weight, 1000 grains weight, grain yield, and field index.The results showed: 1- There was significant between the two varieties Ingath variety superior in all parameters except 1000 grains weight and field index all the studied growth parameters decreased with increase in salinity level to 8 des/m2-Combination of 8 des/m of NaCl plus 8 des/m CaSo4 caused more decreased in all the growth parameters studied as compared with the control test treatment3- Ingath and Milo varieties did not differ in it is effect the growth parameters studied at the level of 4des/m from NaCl plus CaSo4 but it was significant at level 8des/m.
