Salinity is a devastating problem of arid and semi-arid climatic regions with uneven salt accumulation which hinders growth development crops. The deleterious effects salinity mainly depend on level source salinity. We hypothesized that types sodium (NaCl Na2SO4) might cause variable toxicity in maize (Zea mays L.) plants. objective the present study was to compare effect different Na2SO4), each at EC 5 10 dS m–1 growth, physiology nutrient contents plant grown earthen pots under wire house...

The increasing demand for land has resulted in the reduction of potential agricultural land. Land suitability evaluation is an effort that can be made to determine capacity a particular commodity or crop development through various standardized use requirements. East Java as region supplies vegetable commodities on national scale still requires efforts optimize use. This research aimed identify areas have cultivating potatoes. identification was carried out using remote sensing which then...

Restoration of degraded ecosystems is crucial for the conservation biodiversity and provision ecosystem services. In this study, we evaluated success forest restoration efforts in Buner District, Pakistan, by assessing tree species diversity structure. The study area was divided into assisted natural regeneration sites plantations. Altogether thirty (by fifteen plantations) were randomly selected, covering entire area. result revealed that comprised thirteen diverse dominated Pinus...

Lead (Pb) is a ubiquitous pollutant which poses serious threats to plants, animals and humans once entered into the food chain via contaminated industrial effluents on their discharge surface of water bodies and/or geological materials. This study aimed examine compare biosorption potential natural sugarcane bagasse (NB), pyrolysed (PB) acid assisted (APB) for removal Pb from water. To explore this objective, series batch experiments were conducted at various adsorbent mass (0.25, 0.5, 0.75,...

Controlled-release urea (CRU) is widely reported to supply crop nitrogen (N) demand with one basal application, thus effectively replacing split applications of without diminishing grain yield and N use efficiency (NUE). However, its for replacement high-yield (CK) rice untested. In addition, the degree which greenhouse gas (GHG) emissions in systems are affected when CRU substituted CK remains unclear. During 2017 2018, we sampled plant growth a paddy field treated three types...

Heavy metals like chromium (Cr) are hazardous pollutants for aquatic life in water bodies. Similarly, lithium (Li) is also an emerging contaminant soil and which later taken up by plants. The aim of the present study to evaluate removal rate Cr Li Eichhornia crassipes. roots, stems, leaves E. crassipes were evaluated. translocation factor (TF) bioaccumulation (BAF) estimated. Roots accumulated higher concentrations as compared stems leaves. BAF showed that effectively roots Statistical...

Urban air and soil quality has been deteriorating during the past few years due to urbanization, industrialization increased number of vehicles. The goal current study was assess Air Pollution Tolerance Index (APTI) heavy metal absorption (Pb, Cd, Zn, Ni) potential by ten selected trees planted along roadside in metropolitan city Lahore, Pakistan. APTI estimated on basis biochemical parameters (chlorophyll content, ascorbic acid, pH relative water contents) plant extract, while metals (HMs)...
