Bachelor Thesis Summary

Research in the form of experiments on the growth and yield of amaranth (Amaranthus tricolor L. var. Giti Green) at various combinations of NPK fertilizer, had been conducted at Kelurahan Binuang Kampung Pauh In the District Municipality of Padang which starts from April to May 2000.

Plant spinach is a high nutritional value horticultural commodities that are potentially to be developed commercially in supporting the provision of nutritious food for the community, source of family income, and as an ingredient of traditional medicine.

To support the vegetative growth of spinach plants to increase the maximum and high quality results it is necessary to act fertilization through the provision of primary macro nutrient supply (NPK) is sufficient with the appropriate number of comparisons that can support the growth of spinach plants well.

Based on the description above has been carried out an experiment which aims to identify and obtain the best combination of NPK fertilizer for crop growth and yield of spinach.

This experiment used randomized block design (RAK) with 6 treatments and 3 groups. Obtained data were statistically analyzed by F test at 5% significance level and if significantly different then followed by Duncan’s New Multiple Range Test (DNMRT) at 5% significance level. The treatments were: (A) 45 kg N / ha + 18 kg + 22 kg K2O P2O5/Ha, (B) 68 kg N / ha + 36 kg + 33 kg K2O P2O5/Ha, (C) 90 kg N / ha + 54 kg + 44 kg K2O P2O5/Ha, (D) 113 kg N / ha + 72 kg + 55 kg K2O P2O5/Ha, (E) 135 kg N / ha + 90 kg P2O5/Ha + 66 kg K2O, and (F) 158 kg N / ha + 108 kg + 77 kg K2O P2O5/Ha.

The observed variables are the components of growth (plant height, root length riding, the number of plant leaves, and total plant leaf area), yield components (total wet weight of plant and total dry weight), and growth characteristics (growth rate and plant relative growth rate relative leaf plants).

The results showed that administration of a variety of different combinations of NPK fertilizer showed significant effect on total plant leaf area and total dry weight.

Giving combination of NPK fertilizer with a dose of 150 kg Urea / ha + 100 kg SP-36/Ha + 60 kg KCl / ha, equivalent to 68 kg N / ha + 36 kg + 33 kg K2O P2O5/Ha have to increase the vegetative growth spinach plants well.
