“…Increasing salinity level leads to mortality of the plants. The mortality increased significantly due to increasing number of saline water irrigations from vegetative to pod formation similar results was found by Shanti et al (2014).…”

“…These findings clearly indicated that even though the water is available the plants unable to take the nutrient and water from soil due to blocking of salts to the phloem and xylem vessels and prevent uptake of nutrient and water by the plants. This ultimately leads to growth retardant and drying of plants by increasing salt concentration, similar finding was also reported by Shanti et al, 2014.…”

Background: Blackgram is one of the important grain legumes in India. Pulses are the important source of protein for the vegetarian people. To meet out the current demand of pulses, there is a crucial need to increase the blackgram production. Mostly this crop is cultivated in marginal lands where the abiotic stresses like drought and salinity are predominant. The area under salinity in India is 6.73 million hectares and in blackgram no variety was identified as suitable for saline areas.Methods: This experiment was carried out to study the salinity tolerance levels of balckgram genotypes at vegetative and reproductive stages during Rabi season of 2018-20. A total of six blackgram genotypes were used to screen its performance under saline environment at vegetative and reproductive stage. All the genotypes were raised in pot with the size of 20 cm height and 15 cm width with four replications and salinity were stimulated artificially viz., 4.0 EC, 11.0 EC and 16.0 EC ds/m, its growth habits were observed.Conclusion: Salinity impact adversely affects blackgram genotypes under study. The number of days to survival of the plant and plant height were decreased by increasing salinity level and number of irrigation with saline water and it was reduced to ½ at 16 EC ds/m as compared to control. Days to 50% flowering, chlorophyll content and single plant yield were severally affected by increasing salt concentration. Increasing salt concentration was found directly proportionate to increasing number of days taken for flower initiation and at high level of salinity (16.0 EC ds/m) the plants dried before flowering. The plant yield was much affected by slight increase in salt concentration. At 4.0 EC ds/m level the yield was reduced to ¼ as compared to control. The 100 grain weight was not much affected by increasing salt concentration; Chlorophyll content also reduced 2/3 by increasing salt concentration after 15 DAS. The genotypes VBG-14-016 performed better under 4.0 EC ds/m level and survived for more number of days followed by the variety VBN 8.

“…The decreased growth with the increasing salinity level was possibly due to adverse effect, which hindered seedling growth and biomass production. These results are in harmony with those obtained by Reddy et al [15]; Shanti et al [3]; Jamal uddin et al [16].…”

Water is a second most important resource in agriculture followed by land. The water availability for irrigation is often scarce, is one of the most critical input for agriculture production in most areas. Productivity in these areas can be enhanced by better management of rainwater and /or development of groundwater. So the present investigation was carried out to study the effect of saline water irrigation on the growth of blackgram. The various treatment included in the study were three ruling varieties of blackgram as factor V viz., V1- VBN 6, V2- VBN 4 and V3- VBN 3 and four salinity levels as factor S viz., S1-EC-3 dS m-1 and Sodium Absorption Ratio (SAR) - 4; S2-EC- 3 dS m-1 and SAR-6; S3-EC-3 dS m-1 and SAR-8; S4-EC-6 dS m-1 and SAR-6. The experiment was laid out in a Factorial Completely Randomized Design (FCRD) with three replications. The results of the study concluded that the soil application of saline water (EC-3 dS m-1 and SAR-4) irrigation to saline tolerant blackgram variety VBN 3 (S1V3) was identified as best treatment combination to realize the maximum germination of blackgram under saline water irrigation.
