This post is published by AgriHunt staff member. 2SO2(g) + O2(g) â 2SO3(g) + 100 kJ/mol To be economically viable, this process must yield as much SO3 as possible in the shortest amount of time. For example: A parabola is represented by the equation y = x^2 + 8x. To accurately describe the remaining straw C dynamics, we compared one-, two-, and three- exponent equation to determine the number of C pools: (1) R t = R 1 e â k 1 t (2) R t = R 1 e â k 1 t + R 2 e â k 2 t (3) R t = R 1 e â k 1 t + R 2 e â k 2 t + R 3 e â k 3 t where R t is â¦ Harvest index is influenced by hereditary material as well as different environmental factors. It is the ratio between grain yield and plant yield. And it is different for each crop. 6 hours ago. B. Crop Index Crops are listed alphabetically by genus and common name. general equation of a circle formula, However, if the center of the circle is not the origin of the coordinate axes, and is represented by any random point, say (h,k), then the equation of the circle becomes: (x-h) 2 + (y-k) 2 = r 2 In order to arrive at the equation of a sphere, we need to apply the Pythagorean theorem twice. Regional and income group aggregates for the FAO's production indexes are calculated from the underlying â¦ But usually, harvest index vary from crop to crop. y=3/2 - x. therefore gradient is -1 (coefficient of x (the number that is touching with x)) b) (0,c) = (x,y) therefore substitute in eqn: 0 in x. These factors are not same for all crops but variation exists. The equation for figure 2 is the differential of equation 1.1 (Verhulst's 1838 growth model): = (â) (equation 1.2) can be understood as the change in population (N) with respect to a change in time (t). Writing an equation to represent a situation can help us express how quantities in the situation are related to each other, and can help us reason about unknown quantities whose value we want to know. What made you want to look up crop index? 2y+2 (0)=3. By adjusting the albedo and the aerodynamic and canopy surface resistances to the growing characteristics of the specific crop, the evapotranspiration rate can be directly estimated. It is the ratio of the total grain production of a crop to its biomass. limitation is represented by the difference between the lines corresponding to Eqs. These cereals are the rich source of carbohydrates, provide many minerals, and also provide protein and as a rich source of vitamins. In addition to its core functions, represented by equations (1) and (2), an extensive set of additional model components have been incorporated that includes: the climate, with its thermal regime, rainfall, evaporative demand and carbon dioxide concentration; the crop, with its development, growth and yield processes; Lv 7. y=3/2 - 2x/2.
