Divergent consequences of bio-resources on morphological plasticity and biochemical responses in early-stage leguminous species:Sustainable productivity approaches

Inorganic resources can be detrimental to the environment when exploited.In comparison,organic resources help balance the soil’s carbon and nitrogen(C/N)ratio,enhance soil fertility and benefit ecological protection.Current climate crises,rapid urbanization,and fast population growth are causing many natural forests to be converted to agricultural and industrial lands to fulfill ever-increasing food and developmental requirements.Application of different bio-resources becomes necessary for sustainable productivity of available lands.This study explores the effects of various organic amendments on the growth,morpho-physiological and biochemical attributes of three leguminous tree species:Dalbergia sissoo,Vachellia nilotica,and Acacia ampliceps,concerning sustainable productivity.One-year-old healthy,disease-free,and homogenous seedlings were used as study material in a greenhouse pot experiment.Four organic amendments,i.e.,compost(CMP),cow dung(CD),poultry manure(PM),and biochar(BC),along with a control(CK)treatment,were applied.Results showed that all the organic amendments performed significantly better(P<0.05)than CK.CD produced the most significant results,followed by BC application,while PM influence was the least.Among all treatments and species,the maximum values of root length,root biomass,chlorophyll content,carotenoids,catalase,and total phenolic content were recorded under the CD treatment.Whereas for plant height and collar diameter,no big differences were observed between CD and BC(P=0.054).While comparing species,V.nilotica growth was significantly enhanced under organic amendments,followed by A.ampliceps.Combined and comparative results of studied parameters conclude that CD and BC were the most effective organic amendments,which greatly improved the growth of experimental leguminous tree species;this makes these two biofertilizers a powerful tool for sustainable agricultural productivity.Our study contributes toward an enhanced understanding of plant’s morpho-physiological responses,biochemical growth patterns,controls,and activities under different bio-fertilizers.

Morpho-anatomical adaptations of dominantly grown wild Datura inoxia to wastewater resource:Productivity and ecological issues

With the increasing global water scarcity,wastewater irrigation has become widespread,but it can have detrimental ecological consequences.Although wastewater contains valuable nutrients for plants,improper treatment or the use of untreated wastewater in irrigation can negatively impact soil fertility and plant growth.This study is divided into two parts:firstly,a phytosociological survey was conducted to identify plant species with the highest importance value index(IVI)in the vicinity of wastewaterirrigated areas.Secondly,a comparative morpho-anatomical analysis was carried out to investigate the morpho-anatomical adaptations of the species with the highest IVI under wastewater irrigation compared to normal water irrigation.The results of the phytosociological survey revealed the presence of 51 plant species in the vicinity of the wastewater-irrigated areas,with varying relative densities and coverage.Datura inoxia exhibited the highest IVI(28.79),followed by Xanthium strumarium(24.34),while Lippia nodiflora showed the lowest IVI(1.86).The morphological growth of D.inoxia was superior under normal water irrigation,but the average root length was greater under wastewater irrigation.Regarding cell anatomy,cell thickness and cell area characteristics in the dermal,ground,and vascular tissues of the stem and root tended to be greater under wastewater treatment.However,the opposite trend was observed in leaf anatomical analysis,possibly due to the combined effect of wastewater and climatic conditions.Stem and root xylem thickness were greater under wastewater irrigation,whereas phloem thickness was higher under normal water irrigation.The number of vascular bundles in the stem,root,and leaf was higher under wastewater treatment compared to normal water irrigation,but their arrangement was circular in the latter and scattered under wastewater irrigation.Datura inoxia demonstrated strong adaptive potential under wastewater irrigation,as indicated by its highest relative density,coverage,and IVI,suggesting its suitability for phytoremediation.However,due to the low relative density,coverage,and IVI of many other species,the use of untreated wastewater for irrigation cannot be appreciated.
