A comprehensive review of literature on container size, root restriction, and plant growth, along with suggestions for future research and concern are provided. Transplants for both vegetable and floral crops are produced in a number of various sized containers or cells. Varying container size alters the rooting volume of the plants, which can greatly affect plant growth.

Each factor had three levels thus 3 x 3 factorial design was used to investigate the factors. It was found that all the three factors had significant impact on the number of broken grains. The optimum parameter settings that led to the smallest percentage of broken rice grains were as follows: size of hopper feed at 12 cm 2, gap adjuster at 5 ...

The grinding mill is one of the important mining machines. When grinding materials, the output of grinding mill will be affected by many factors, mainly by the particle size of the finished product, the hardness of the material, the humidity of the material, the composition of the material, the viscosity of the material, the working efficiency of the supporting measures …

The quality of the machining is measured from surface finished and it is considered as the most important aspect in composite machining. An appropriate and optimum machining parameters setting is crucial during machining operation in order to enhance the surface quality. The objective of this research is to analyze the effect of machining …

kernels have a significant impact on the effectiveness of milling. The main factors that influence the properties of kernels during milling are hardness and vitreousness (GREFFEUILLE et al. 2007a,b). The hard wheat varieties produce higher yield of flour since the endosperm is more effectively separated from bran (POSNER 2003b). The hardness of ...

The standard closed circuit comminution process commonly employed in industrial vertical roller mills has been analyzed to determine the influence of typical abrasive minerals on wear rates. With the main focus on raw mixes used in …

and discussed the influence of the yield curve on load distribution. In order to study the load distribution, CHEN Haiping [15] discussed the analytical, photo elasticity and 2D FE methods, and the factors, which affect the load distribution are systematically studied, and the main factors were investigated by regression analysis.

Combining these two influences upon the vertical displacement yields the following equation. y = v iy • t + 0.5 • g • t 2 (equation for vertical displacement for an angled-launched projectile) where v iy is the initial vertical velocity in m/s, t is the time in seconds, and g = -9.8 m/s/s (an approximate value of the acceleration of ...

Ethylene. Leaf growth and development are affected by various environmental factors and endogenous hormonal signals (Table Table1 1).These processes are regulated by phytohormones, transcriptional regulators and mechanical properties of the tissue (Bar and Ori, 2014).The role of ethylene in the leaf growth and development has been confirmed …

Studies have shown that soil pH can influence crop yields, soil nutrient release, and soil microbial activity to a large extent [10, 11]. If farmland soil is too acidic or too alkaline, then land production will be limited . Soil pH is an important regulator of soil and is inevitably controlled by different soil-forming factors [13–16].

Fig. 3: Effect of variety on hullability assessed by test milling Effect of agronomic factors Agronomic guidelines for the oat crop are well-established in terms of yield and lodging. However, the effects of agronomic factors on quality are less clear due to the absence of methods to assess the processing characteristics directly related to

In this paper, two methods of orthogonal numerical simulation test and similar material simulation test are used to study the influence of five factors on the stability of rectangular roadway: roadway width, roadway height, roadway buried depth, lateral pressure coefficient of surrounding rock, and comprehensive strength of surrounding rock.
