  A field experiment was conducted to determine the effect of different tillage implements and rice stubbles as residue on the yield of wheat in saline-sodic soil. Rotavator proved the best among all the tillage implements producing maximum germination counts (35.5 m-2). no. of tillers (289.49 m-2); 1000 grains wt. (45.52 g), grain yield (3.409 t ha-1) and straw yield (3.42 t ha-1). Rice stubbles had better residual effect giving significantly higher values of these parameters than the rice stubbles removed from field before sowing the wheat crop. Incorporation of rice stubbles into soil proved also beneficial in improving health of saline-sodic soil.

  Two genotypes, i.e. Pb-28 and Bakhtawar were proved to be tolerant as they showed better growth and produced maximum grain and straw yield under salinity stress. The performance of two genotypes (Pb-39 and KLR-1-4) under salinity was very poor and were declared as sensitive. Rest of the genotypes were either moderately tolerant or moderately sensitive depending upon their performance under salinity stress.

  In a solution culture study two rice varieties i.e. KS-282 (salt tolerant) and BG 402-4 (salt sensitive) were grown to determine the effect of Zn applied @ 1, 10, 100 and 1000 nM ZnSO4 on shoot fresh weight and concentration of Na, K, Cl, Zn and P, when exposed to NaCl salinity (0 and 70 mol m-3 NaCl). Addition of Zn caused increase in shoot fresh weight under both saline and non-saline conditions, however growth was higher under O salinity. Concentration of Zn, P and K were increased while those of Na and Cl decreased in shoot under saline conditions. Salt tolerance rice maintained low concentration of Na, Cl and P but higher that of Zn and K.
