Evaluation of genotypic behavior of wheat (Triticum aestivum L.) in saline-sodic soil conditions
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2017, Vol 11, Issue 5
Abstract
Salinity is one of the major constraints of the world that hampers the agricultural production. A relatively simple and practical way of improving crop yield and profitability to sustain food production on these problematic soils is to identify those genotypes that are tolerant to salinity and/or sodicity. To investigate the genotypic behavior of wheat against tolerance to high soil salinity and/or sodicity, a field experiment was conducted in saline-sodic soil using four different wheat genotypes i.e. SARC-1, SARC-2, SARC-3 and Pasban-90. The experiment was laid in a randomized complete block design (RCBD) with four replications. The treatments were categorized as T1 (EC 3.71 dS m-1), T2(EC 5.85 dS m-1) and T3(EC 10.56 dS m-1) on the basis of pre-sowing soil analysis. At harvest, the data regarding plant height, spike length, 1000-grain weight, total dry matter, No. of spikelets spike-1 and grain yield was recorded and analyzed statistically. Soil, leaf, grain and straw samples were also analyzed for N, P, K and Na+ analysis. SARC-3 performed well on the basis of growth and physiological parameters compared with other genotypes. At high salinity i.e. at T3 where EC level was in the range of 9.5-11.50 dS m-1, it produced maximum spike length, 1000-grain weight, number of spikelets spike-1, total grain weight and total dry matter weight. At the other two treatments its performance was also better than the other genotypes however further studies are needed to categorize the highest potential of these genotypes in saline-sodic soils.
