  The effect of salinity on morphological characters of salt tolerant genotypes PVSB9, PVSB19, PNR381, PNR519, Iratom24 and salt sensitive genotype NS15 along with one standard check salt tolerant rice cultivar Pokkali were assessed in two factors Completely Randomized Design with four replications. Seven rice genotypes in combination with six levels of salinity (0, 3, 6, 9, 12 and 15 dS m-1) were randomly assigned in 168 experimental plastic pots. The different morphological characters studied include plant height, total number of tillers, Root Dry Weight (RDW), Shoot Dry Weight (SDW) and Total Dry Matter (TDM) content of the selected rice genotypes in view to evaluate their response at different salinity levels. The results on the effect of morphological characters indicated that plant height, total tillers, root, shoot and total dry matter were significantly decreased by the application of salinity. The genotypes Pokkali, PVSB9, PVSB19 showed significantly higher values and the lowest value of all these characters were recorded in NS15. A sharp decrease in percent relative- plant height, RDW, SDW, TDM, total tillers were found in susceptible genotype NS15 after 3 dS m-1 level of salinity, but these characters were found to decrease slowly in tolerant genotypes.

  The effect of sulphur (S) and zinc (Zn) on nodulation, dry matter yield, nutrient content of soybean cv. Shohag (Pb-1) was studied during December, 2001 to March, 2002. The levels of S and Zn employed were 0, 10, 20, 30 and 50 kg S ha-1 and 0, 2.5, 5, 10 and 20 kg Zn ha-1, respectively. The results indicated that among the S treatments, S30 gave the highest number of nodules plant-1 mostly at the later stages of growth though the effect was not significant. Zinc also did not show any significant influence on nodulation of soybean. The highest number of nodules were obtained from Zn20 at 90 (DAS). Dry matter yield at different growth stages were significantly affected with the increasing levels of S and Zn application. Sulphur and zinc contents were also significantly increased with the increasing levels of S and Zn up to 30 kg S and 20 kg Zn ha-1 in most of the growth stages and then decreased with higher levels of S.
