Response in growth of maize to temperature was studied under controlled conditions. The growth of plants was measured in terms of :
I. Growth characters
A. Stem, (1) surface area (πdh) (2) volume (πr2/h)
B. Leaves, (1) area, (2) dry weight
II. Growth attributes or physiological components of growth
A. Net assimilation rate (NAR)
B. Relative growth rate (RGR), (1) dry weight (R), (2) leaf area (RL)
C. α coefficient (R/RL)
III. Morphological components of growth
A. Leaf area ratio (LAR) : leaf area/total dry weight
B. Leaf weight ratio (LWR) : leaf weight/plant weight
C. Specific leaf area (SLA) : leaf area/leaf weight = 1/leaf thickness. The response was measured in terms of these characters and critically
analysed in relation to temperature and age of plants.

Corn stover, which includes stalks, leaves, and husks left in the field after harvest, holds promise as a feed source for ruminant livestock due to its nutritional value. However, a lack of research on its nutritional composition has led to wasteful practices like open burning and disposal. Therefore, this study aims to determine and compare the nutritional value of corn stover between sweet and kernel corn. The samples of corn stover were collected at Universiti Sultan Zainal Abidin Farm. All samples were subjected to the cleaning, chopping, drying, and grinding processes before undergoing nutritional analysis using proximate analysis. The proximate analysis was measured based on the percentage of crude protein, ash, crude fibre, moisture, and fat. The results indicate that sweet corn stover exhibits the highest nutritional value (p< 0.05) in terms of ash, crude protein, and fat, with percentages of 5.44%, 19.04%, and 3.86%, respectively, particularly in its leaves. Additionally, the stalks of sweet corn stover contain the highest percentages of moisture (4.89%) and crude fiber (27.05%). This study found that sweet corn stover is more suitable for ruminant feed because it contains the highest levels of essential nutrients like crude protein, fat, and ash.
