Irrigation water scheduling methods influence the growth, yield, and productivity of crops including potatoes. Therefore, a study was conducted to evaluate effects irrigation frequency determination on tuber fertilizer use efficiency potatoes at Koga scheme, in Northwest Ethiopia. The treatments were consisted two (wetting front detector crop requirement) six NPS rates (0, 90.8, 136.2, 181.6, 2...

To contribute the biological mean of CO2 fixation, more than 200 microalgal isolates were screened from lakes, ponds, sediments, hog wastewater, paddy fields, hot springs, and seawater in Taiwan. Two unicellular microalgae, Chlorella sp. NTU-H15 and Chlorella sp. NTU-H25, were isolated from hog wastewater. In the laboratory, they were able to grow up even in aeration containing CO2 up to 40% an...

The argan tree, which is found in southern Morocco, characterized by environmental, economic and nutritional benefits, but the growth of this tree very slow. This makes it necessary to find methods accelerate its growth. A pot experiment was conducted evaluate effects biochar (BC) bio-compost (CP) each applied at rate 0, 3 6% (M/M) on starting fine silty soil for sixteen months. Main stem lengt...

Sustainable agriculture is an important global issue. Organic fertilizer application improves crop growth by supplying plant nutrients, including micronutrients, as well improving the physical, chemical, and biological properties of soil, thereby providing a better environment for root development soil structure. It has been widely reported that continuous applications inorganic fertilizers alo...

Accurate and timely information on rice crop growth and yield helps governments and other stakeholders adapting their economic policies, enables relief organizations to better anticipate and coordinate relief efforts in the wake of a natural catastrophe, and provides technical backbone of an insurance solution where risks of yield losses from the rice smallholders are transferred to the insuran...

Numerous studies have addressed effects of rising atmospheric CO2 concentration on rice biomass production and yield but effects on crop water use are less well understood. Irrigated rice evapotranspiration (ET) is composed of floodwater evaporation and canopy transpiration. Crop coefficient Kc (ET over potential ET, or ETo) is crop specific according to FAO, but may decrease as CO2 concentrati...

In Pakistan, on-demand availability of groundwater has transformed the concept of low and uncertain crop yields into more assured crop production. Increased crop yields have resulted in food security and improved rural livelihoods. However, this growth has also led to problems of overdraft, falling water tables, and degradation of groundwater quality, and yields generally remain well below pote...

This study was carried out to determine the effects of Immunogen as a prebiotic on growth-related parameters and gut micro-flora in R. kutum fry. A basal diet was formulated using common feed ingredients supplemented with Immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets.  Fish were randomly distributed in 500 L fiberglass tanks (1×1×0.5 m). The experiment lasted for eight ...
