Synopsis

Wheat is a cereal that is very important as a source of food in the world with the largest amount in the supply of staple food for the world's citizens. Constraints encountered in Indonesia are temperature, rainfall, and high humidity. In addition to these environmental factors, another obstacle is the adequacy of nutrients from the soil that affects the growth, development and productivity of wheat. This study aimed to examine the productivity of wheat varieties in the middle plains and to examine the physiology of wheat in the middle plains. This research is a single-factor pot experiment conducted in a Completely Randomized Design. Dewata varieties were given 0 g NPK fertilizer, 2.5 g NPK, 5 g NPK, 7.5 g NPK, and 10 g NPK given each per polybag, the treatment was repeated three times. Observations were made on plant height, number of leaves, age of flowering, number of tillers, and chlorophyll content. Data
were analyzed by Analysis of Variance using the SAS 9.1 for Windows program and continued with testing using the Least Significant Difference Test. The results showed that NPK fertilizer 5 g per plant can increase vegetative growth on the plant height, chlorophyll content the total leaf most high, days to flowering more quickly, while the NPK fertilizer 2.5 g per plant can increase the number of leaves and number of tillers, the highest.
