Sustainable Food System and GM Foods in Era of Climate Change and Variability: Indian Perspective Authored by RK Gupta Agriculture and allied sectors are backbone of Indian economy. They are source of living for over 70 per cent of the population and provide around 50 per cent of employment in country. India has witnessed appreciable agriculture growth through crop improvement efforts, technological interventions and policy support. The food grain production has increased from 51MT (1950- 51) to 285 MT (2018-19). Rice, wheat, pulses, oilseeds, sorghum, and maize are important field crops. The cotton and sugarcane are the principal commercial crops. Livestock and horticulture sectors have also contributed significantly in Agriculture GDP. India has one-half of the buffalo and one-sixth of the cattle population of the world. It ranks first in goat and sixth in sheep population besides vast potential of fishing resources. India has huge challenges in terms of population growth that is li...

Environmental Impact Assessment and Source Identification of Total Suspended Particulate Matter and Some Elements Emitted from a Workplaces in Jordan Authored by Omar Ali Al Khashman The objective of the present study was to assess the extent and severity of atmospheric particulate concentrations and metal concentration in dust, street dust and soil in the Aqaba Industrial Estate (AIE). Samples of dust, street dust and soil were analyzed for their contents of atmospheric particulate matter and elements (Fe, Cu, Ni, Pb, Zn, Mn and Cr) after digestion with nitric acid. This study shows that analyzed major sources and magnitude of elements pollution. The mean concentrations of the elements were as follows: CFe > CPb > CZn > CCr > CMn > CCu and CCd where C stands for concentration. Zn, Cd and Pb were in high levels in the area close to the workplace, while the chromium level was low. This study indicates that all of the elements are concentrated on the surface soil, and dec...

Influence of Planting Dates on Cane and Sugar Yields for Some Sugarcane Varieties Authorized by Mohamed Owais Ahmed Galal The present study was carried out at El-Mattana Research Station, Luxor Governorate, Agricultural Research Center, Egypt. In two plant crop seasons of 2017/2018 and 2018/2019 to study the effect of planting dates on yield for three sugarcane varieties (G.T.54-9, G.98-28 and G.84-47) grown at three planting date in mid-March, mid-April and mid-May. The date of harvesting was in mid-March for all planting dates. A split plot arranged RCBD, in four replications, was used for the experiment. The three varieties were randomly distributed to the main plot while the three planting dates were assigned to sub-plot. The results indicated that planting sugarcane in mid-March was superior in millable cane/fed, cane weight, as well as cane and sugar yields in both seasons. The commercial sugarcane variety G.T.54-9 surpassed the other two varieties in the number of m...
