“…This may have happened due to supplemental irrigation of saline water resulting in the accumulation of salt in the dry/summer season, but that partially leached out in the following kharif season as a result of ample rainfall. A similar increase in soil EC values in long-term salinity trials with groundnut was earlier reported (Bhaduri et al, 2016;Bhaduri et al, 2020). Saline vertisols, dominated by salinization and sodification processes, occupying a large share of salt-affected area (2.22 M ha) are present in Gujarat and productivity of these soils was found to be poor even at low salinity due to the typical physico-chemical characteristics (Chinchmalatpure et al, 2018).…”

An experiment on cowpea-groundnut rotation was conducted to study the effect of saline irrigation water on the availability of micronutrient cations (Fe, Zn, Cu and Mn) in soil and in plants with the effect of a gradual imposition of irrigation salinity (EC iw ). Three saline treatments (S 1 : 2.0 dS m -1 , S 2 : 4.0 dS m -1 , S 3 : 6.0 dS m -1 with a control S 0 ) were maintained in long-term field trials. In summer (cowpea) the soil EC e was raised to 6.01 dS m -1 while in kharif (groundnut) the EC e was 2.21 with S 3 . A noticeable increase in soil pH (from S 0 to S 3 ) was also observed in cowpea (0.48 unit) and groundnut (0.97 unit) seasons. The four available micronutrients in soil did not show any significant trend in both seasons. The concentration of both shoot Fe and Zn increased from control (S 0 ) to highest salinity (S 3 ) to the tune of 19% and 74%, respectively in groundnut. The accumulation of root Fe and Zn in groundnut declined to the tune of 53% and 40% respectively with the increasing salinity from S 0 to S 3 . For cowpea, only Zn content showed a decreasing trend among the other micronutrients. Genotypic variation of groundnut did not affect the accumulation of micronutrients as observed by testing eight groundnut genotypes in the present study. A significant drop in yield was noticed for both crops due to saline irrigation, and the groundnut yield varied between 1.6 t ha -1 (in S 0 ) to 0.14 t ha -1 (in S 3 ). This study marks a relevance where very less information is available on micronutrient availability in plant tissues and soil under changing salinity, especially for groundnut, which is considered an important oilseed crop from the national perspective.

“…Saline has a negative effect on the health status of plants, inhibits the growth processes, decreases the photosynthesis efficiency, leads to physiological drought. Saline and sodication are abiotic soil factors which pose a serious threat to soil fertility and thus affect soil production (Bhaduri et al 2016). To understand the soil system ecology, one must know the activity of soil microorganisms and soil enzymes which show a fast reaction to slight changes in soil environment.…”

Salinity is the key global problem of the soil environment degradation. The paper demonstrates the results of research of the activity of selected soil enzymes (catalase, dehydrogenase, alkaline and acid phosphatase, rhodanase and arylsulphatase) as well as the content of macroelements (available phosphorus, potassium, magnesium and sulphates sulphur) in terms of the principal physicochemical properties. The soil was located in the vicinity of old sedimentation tanks within the impact of the plant of CIECH Soda Polska S.A (the soda plant) in Inowrocław (Central Poland). Pearson's correlation coefficients were applied to assess the interactions between some physicochemical properties, some macroelements and soil enzyme activities. The results have shown that the soil ECe, P, K, Mg and S contents were changing depending on the soil sampling locations. The soil enzymes did not change significantly with an increase in ECe. The activity of rhodanase differed from the other soil enzymes analysed; that one can be used as an indicator of environmental pollutants produced during chemical industry processes. The result of this study found inconsistent salt-affected soil effects on soil enzyme activity. It remains a challenge to thoroughly delineate effects of salt-affected soil on soil process in general and on biochemical processes in particular, and as a result, the selection of the adequate method of revegetating such soil.

“…The conceptual model of Shen et al (2011) depicted a great scope for root/rhizosphere and soil-based nutrient managements for improving P-use efficiency and crop productivity in intensive agriculture. P-uptake of peanut plants was also found to cultivar-specific under similar experimental conditions since cultivars TG 37A and GG 7 accumulated more leaf-P and root-P under long-term salinity trial, when salinity played a crucial role in determining P-uptake (Bhaduri et al, 2016). Poor soil-P availability, high fixation, inconsistent and Phosphorus is an important element for plant growth, essentially required for energy transfer and nucleic acids (Marschner, 1995).…”

Aim: To investigate efficient utilization of soil phosphorus for peanut nutrition through integration of management practices in medium black clay soils of Saurashtra region in Gujarat. Methodology: Soil phosphorus availability and uptake by peanut plants were assessed at five plant growth stages under six different management practices in Kharif season. The availability of soil P was estimated by Olsen P and Resin P extraction methods. The biomass production and phosphorus uptake at each growth stages were observed in order to draw the relationship between these parameters.? Results: The management practices like raised bed with polythene mulch, integrated and organic nutrient management was consistently found promising for enhanced availability and uptake of soil phosphorus under peanut cultivation. The Olsen P decreased with plant growth under all the management options, except organic and integrated nutrient management practices.? In contrary, the resin P generally increased with plant growth, especially under inorganic and organic nutrient management and raised bed with polythene mulch practices. Irrespective of growth stages, the phosphorus uptake by peanut plants was significantly and strongly correlated with biomass production (r=0.85, p<0.01) and Olsen P (r=0.41, P<0.05).? Interpretation: The results indicate that phosphorus requirement of peanut plants can be efficiently met by integrating land and nutrient management practices in these medium black clay soils.
