Boron (B) is an essential micronutrient in the growth of reproductive plant parts. Its deficiency and/or toxicity are widespread in arid and semi-arid soils with low clay contents. This study was planned to determine the response of sorghum (Sorghum bicolor L., non-leguminous crop) and cowpea (Vigna sinensis L., leguminous crop) to boron (0, 2, 4, and 16 µg g−1) on four distinct soil series from Punjab, Pakistan i.e., Udic Haplustalf (Pindorian region), Typic Torrifluvent (Shahdra region), Halic Camborthid (Khurianwala region), and Udic Haplustalf (Gujranwala region). Overall, there was a significant difference (p < 0.05) in yield between the sorghum (3.8 to 5.5 g pot−1 of 5 kg dry soil) and cowpea (0.2 to 3.2 g pot−1 of 5 kg dry soil) in response to B application. The highest yield was observed in both sorghum and cowpea either in control or at 2 µg g−1 B application in all four soils. Cowpea showed the same yield trend in all four soils (i.e., an increase in yield at 2 µg g−1 B application, followed by a significant decrease at the higher B levels). In contrast, sorghum exhibited greater variability of response on different soils; Udic Haplustalf (Pindorian region) produced the greatest yield at low levels of B application. However, Halic Camborthid produced its lowest yield at that level. Boron concentration in shoots increased with the levels of B application, particularly in sorghum. In cowpea, the plant growth was extremely retarded—and most of the plants died at higher levels of B application even if a lower concentration of B was measured within the shoot. Hot water-extractable B was the most available fraction for cowpea (R2 = 0.96), whereas the easily exchangeable B was most available for sorghum (R2 = 0.90). Overall, these results have implications for micronutrient uptake for both leguminous and non-leguminous crops.

Soil contamination with heavy metals is threatening the food security around the globe. Chromium (Cr) contamination results in poor quality and reduction in yield of crops. The present research was performed to figure out the Cr toxicity in sunflower and the ameliorative role of 5-aminolevulinic acid (ALA) as a plant growth regulator. The sunflower (FH-614) was grown under increasing concentration of Cr (0, 5, 10 and 20 mg kg−1) alone and/or in combination with 5-ALA (0, 10 and 20 mg L−1). Results showed that Cr suppressed the overall growth, biomass, gas exchange attributes and chlorophyll content of sunflower plants. Moreover, lower levels of Cr (5 and 10 mg kg−1) increased the production of reactive oxygen species (ROS) and electrolyte leakage (EL) along with the activities of antioxidant enzymes i.e., superoxide dismutase (SOD), guaiacole peroxidase (POD), ascorbate (APX), catalase (CAT). But at higher concentration of Cr (20 mg kg−1), the activities of these enzymes presented a declining trend. However, the addition of 5-ALA significantly alleviated the Cr-induced toxicity in sunflower plant and enhanced the plant growth and biomass parameters along with increased chlorophyll content, gas exchange attributes, soluble proteins and soil plant analysis development (SPAD) values by scavenging the ROS and lowering down the EL. The 5-ALA also enhanced the activities of antioxidant enzymes at all levels of Cr. The increase in Cr concentration in all plant parts such as leaf, root and stem was directly proportional to the Cr concentration in soil. The application of 5-ALA further enhanced the uptake of Cr and its concentration in the plants. To understand this variation in response of plants to 5-ALA, detailed studies are required on plant biochemistry and genetic modifications.

A pot experiment was conducted to investigate the role of potassium (K) in extenuating the injurious effect of salt stress on maize hybrids differing in salt tolerance at different growth stages. One salt-sensitive viz. 8441 and one salt-tolerant viz. 26,204 maize hybrids were sown in pots having 12 kg soil. The recommended dose of nitrogen and phosphorus @ 200 and 150 kg ha−1 with different rate of potassium (75, 150 and 300 kg ha−1) and salinity level (10 dS m−1) was developed in soil before filling the pots. Salinity stress reduced plant growth by affecting plant morphological characteristics, reducing relative water contents and membrane stability index, decreasing photosynthetic activities, altering K+/Na+ ratios and antioxidant activities of both maize hybrids at all three growth stages. However, results also depicts that maximum relative water contents, membrane stability index, gas exchange attributes, photosynthetic pigments, antioxidant enzymes activities and proline contents was observed at reproductive growth stage as compared to vegetative and grain development growth stages in both hybrids. The inhibitory effect of salt stress was more pronounced on maize hybrid 8441 than 26,204. But, addition of potassium significantly alleviates harmful effect of salinity by improving the plant growth, gas exchange parameters, enhancing K+/Na+ ratios and antioxidant activities of both maize hybrids. Potassium application (300 kg K ha−1) was found more effective in alleviating perilous effect of salinity as compared to other two levels. Salt tolerant maize hybrid (26,204) produced more biomass, less shoot Na+ concentration, high K+ concentration, exhibited more chlorophyll contents, gas exchange parameters and antioxidant enzymes activities under salt stress condition at all growth stages as compared to salt sensitive maize hybrids (8441). These results suggested that potassium application counteracted the unfavorable effects of salinity on growth of maize by civilizing photosynthetic capacity of maize plants against salinity-induced oxidative stress and maintaining ion homeostasis, however, these alleviating effects were cultivar specific.

A hydroponic experiment was conducted to investigate single and combined effects of 5 µmol/L Cd and 100 mM NaCl on growth, root morphology, photosynthetic parameters, leaf and root ultra-structure of two maize hybrids (26204 and 8441) differing in salt tolerance. A more pronounced reduction on growth, root morphology, SPAD value, chlorophyll fluorescence and leaf gas exchange indicated that 8441 was more sensitive than 26204 to both Cd and NaCl stresses. Transmission electron microscopy of 8441 revealed a more severe destruction in root and leaf cells as compared to 26204. The reduction in growth and photosynthetic parameters were associated with severe disorganization of nucleus, chloroplast, mitochondrial damage, vacuolation, and increased number and size of pastoglobuli. Interestingly, the combined stress of both NaCl and Cd had obvious beneficial effect on the plant growth, photosynthetic parameters and cell ultra-structure relative to Cd or Na stress alone in the two maize hybrids. The study suggested that there is involvement of same genetic and physiological mechanisms in response to both Cd and NaCl stresses.
