Review of Literature Alaskan peas have the shortest growing season of all pea types. This strain was developed to adapt to short growing seasons and colder climates. They were developed in 1881 by Thomas Laxton. They grow to be approximately 3 feet tall, and its pods produce 5-8 seeds. In an optimal environment, they can be grown year round. Most authorities recommend that Alaskan pea seeds are to be planted between an inch to an inch and a half deep, which is approximately 5 centimeters.
In the groups where the seeds were planted 5cm and 4cm deep, only 1 seed in each group did not sprout. The experiment refuted the hypothesis, which stated that the seeds planted at 5 cm would grow the tallest. The seeds that were planted 4 cm deep grew the tallest. This was probably because the higher planting level allowed for the peas to grow more roots, and therefore taking in more water. Some conclusions that could be drawn from the data were that the plants that were planted at 6cm grew the least because they had to grow up through more soil to get sunlight. The averages between the seeds planted at 5 and 6 cm deep were within a centimeter of each other, which could possibly be within the margin of
