Effect Nutrient "N" Dose on Growth and Protein Content of Napier Pakchong Grass and Zanzibar Napier Grass

Abstract

The purpose of this study was to determine the effect of the dose of nutrient N on the growth and protein content of napier pakchong grass and napier zanzibar grass. The experiment was arranged using a randomized block design (RAK) with a single factor, namely the dose of N fertilizer on two different types of napier grass, including (1) The dose of N fertilizer was 60 kg/ha on the type Napier Pakchong Grass (2) The dose of N fertilizer is 150 kg/ha on the type of Napier Pakchong Grass. (3) The dose of N fertilizer is 240 kg/ha on the type of Napier Pakchong Grass. (4) The dose of N fertilizer is 60 kg/ha on the type of Zanzibar Napier Grass (5) The dose of N fertilizer is 150 kg/ha on the type of Napier Zanzibar Grass (6) The dose of N fertilizer is 240 kg/ha on the type of Napier Zanzibar Grass. The results of this study showed that there was a very significant response to the variable height of the plant throughout the observation period, the observation of the number of tillers and the number of leaves showed a significant response at the age of 14, 28 and 70 days after planting. The stem diameter showed a significant response only at the age of 14 days after planting and also gave a very significant response to the wet weight observation variable but did not give an unsignificant response to the dry weight observation and protein content test.
