The Most Dangerous Game, written by Richard Connell, is a thrilling short story about a hunter named Sanger Rainsford who becomes the prey in a twisted hunting game organized by a wealthy Russian aristocrat named General Zaroff.

The story begins with Rainsford and his friend, Whitney, discussing their differing beliefs about the value of hunting. Rainsford, an experienced hunter, believes that hunting is the ultimate sport because it requires skill and strategy, while Whitney sees it as a barbaric and unnecessary activity.

As the story progresses, Rainsford finds himself stranded on an island after falling overboard from his yacht. He is eventually discovered by General Zaroff, who invites him to stay at his mansion on the island. However, Rainsford soon learns that Zaroff has a twisted hobby: he hunts humans as the ultimate prey.

Zaroff tells Rainsford that he has grown bored of hunting animals and has turned to hunting humans because they provide a more challenging and exciting hunt. He offers Rainsford the chance to join him in the hunt, but Rainsford refuses and becomes the target instead.

The story reaches its climax as Rainsford uses his skills as a hunter to outwit Zaroff and turn the tables on him. In the end, Rainsford emerges as the victor, having proven himself to be the better hunter.

The Most Dangerous Game is a thrilling and suspenseful story that explores the themes of survival, the value of human life, and the dark side of human nature. It highlights the dangerous consequences of allowing one's desires and ego to override moral principles and shows the power of intelligence and resourcefulness in overcoming adversity.

Overall, The Most Dangerous Game is a thought-provoking and entertaining tale that serves as a cautionary warning about the dangers of indulging in dangerous and unethical pursuits.

Harvest index

Notice that within the same year, there is variation in the harvest index. The grain is the most economically valuable part of the corn plant and management decisions should be based on maximizing profit from grain yield. Harvest index is not necessarily something that you should manage directly. In this review two main ways for improvement of maize HI are suggested: Increase in kernel setting and decrease of vegetative shoot biomass. Usually the biomass of above ground is taken instead of below ground biomass, because the below ground biomass also includes the roots and the process of taken the root biomass is difficult and during experiment, chances of error increases.

How harvest index relates to crop yield

define harvest index

Harvest index is a simple way to estimate how much stover you have in the field. In salt-stressed maize plants which are particularly prone to kernel abortion, a decrease in plasma membrane H +-ATPase activity in kernels was found around pollination. Cereals are those crop which provide the edible seeds like rice, wheat , lentil is considered as cereals. Stover can be harvested and used as a livestock feed, converted into ethanol or burned for heat or electricity. Averaged over all wheat classes and regions the HI was 0. The DA-Meter device do not require the destruction of the fruit sample considered and allow to monitor the fruit growth and the ripening evolution in planta. While this is a good rule of thumb and can be used to estimate stover production on various fields, it is important to understand that this number can vary widely from year-to-year and from soil type to soil type.

Harvest Definition & Meaning

Mostly, modern cultivars have 0. Using on-going variety performance trials in eight states, a total of 255 varietal trial entriess from five classes of wheat were surveyed for above-ground biomass. With advanced breeding, genetics and more intensive management, higher crop yields can be achieved with the same size plant, resulting in higher harvest index. And it is different for each crop. After this proof of concept increase of maize HI is possible without grain yield losses , the identification of the responsible physiological mechanisms is necessary in order to apply the knowledge to other maize genotypes and to a broader range of growth conditions, eventually contributing to a more sustainable crop production. For questions or comments, please contact. This study was conducted to evaluate straw yield potential and its relationship with grain yield for wheat Triticum spp.

Harvest index and straw yield of five classes of wheat

Wheat straw is a potential cellulosic feedstock for bioethanol. The amount of wheat straw available as cellulosic feedstock in a state or wheat class can be estimated using the grain yield estimates provided by the National Agricultural Statistics Service and the class specific HI. The development of innovative methods for reducing the ripening variability is essential, so that fruits apparently homogeneous on the basis of the quality traits normally used can be more reliably classified in uniform groups allowing a better post-harvest management. Hence, for the better utilization of all of these, the human body required a food in a proper dose. The parents were different in some quantitative traits Table 1 T-test showed that the results of hybridizing of the parents were meaningfully different from traits like length of ears, weight of seed in plant, ear density ratio, and number of days till appearance of ear, and physiologic growth and harvest index.

Harvest index: A predictor of corn stover yield

define harvest index

Harvest index is defined as the pounds of grain divided by the total pounds of above ground biomass stover plus grain. A crop yield will be higher when its harvest index will be higher. These factors are not same for all crops but variation exists. These cereals are the rich source of carbohydrates, provide many minerals, and also provide protein and as a rich source of vitamins. For the reduction of vegetative biomass, the focus lies on the the phytohormones gibberellins GAs. Optimum plant height is considered as an important trait for avoiding lodging, thus maximizes harvest index. However, the production of vegetative biomass which is usually not utilized requires high amounts of water and nutrients.

Harvest index for bioenergy crop research plots at various locations for 2009 to 2012. Corn stover is made up of the stalk, leaves, husks and tassels left in the field after harvesting the grain with a combine. Hard red winter wheat in the southern plain states of Texas and Oklahoma had, on average, the lowest HI. Table 1 shows data from Table 1. This study focused on the definition of the proper harvesting time of the ‘Gala’ fruit in Piedmont growing areas using the I AD non invasive method.

But usually, harvest index vary from crop to crop. The amount of stover produced each crop year depends on weather, soils and management practices like fertilizer and pest control applications. Thus, it can be used as selection criterion for the productivity of a crop. As new opportunities arise for harvesting corn stover for livestock feed or for bioenergy, farmers will want to keep better track of how much stover they have left in the field after harvest and the value of that stover. The yield of a crop can be basically depends upon many factors that may be endogenous factors or exogenous factors.

Harvest index for different crops: For each crop, harvest index vary and for production of a crop per hectare on international basis, the value of H. This is commonly expressed in a ratio called harvest index. As with the passage of time, the population is increasing day by day, food is required more and hence yield of a crop is required in higher amount. This is due to the variability in soil types, geographic distribution of rain and to a lesser extent, management of the corn crop. In normal years, the harvest index generally hovers around 0. In maize, opposite to wheat, a close positive correlation exists between dry matter accumulation and grain yield. It is hypothesized that with application of phytohormones, specifically auxins, H +-ATPase activity can be enhanced, leading to an improved transport of hexoses into the developing kernels and thus to a better kernel set.
