Baubau City is one of the cashew (Anarcadium occidentale L.) producer area in Southeast Sulawesi with area of 820 ha. This large area of cashew cultivation was not compensated with the productivity caused of low production. An effort to overcome this problem is identifying the growth and yield characters of cashew to apply the good agricultural practices for cashew plantation. The objective of this research was to determine the growth and yield of two cashew varieties at different tree ages; and to identify the relationship between the characters and the productivity of cashew trees in Baubau City. This research was arranged by oversite design with 2 varieties (the cashew with red pseudo-fruit and the cashew with yellow pseudo-fruit), 4 ages of cashew plant (5 years old, 17 years old, 26 years old, 37 years old) and 5 replications. The results showed that both varieties had no significantly different on growth and yield characters. At 37 years old, cashew trees still demonstrated the increasing of the productivity due to the increasing of growth and yield component i.e. plant biomass, the number of flower, the number of cashew nut per plant and cashew nut weight per kernel.

Penelitian ini bertujuan untuk mengetahui pengaruh mineral nitrogen dan besi terhadap sifat fisiologis dan pertumbuhan tanaman terong lokal buton (solanum melongena L). Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) faktor tunggal. Perlakuan berupa pemupukkan dengan membuat larutan Hoagland sebanyak tiga jenis yaitu larutan lengkap, larutan tanpa N, larutan N tiga kali, larutan tanpa Fe, dan larutan Fe tiga kali. Masing-masing perlakuan diulang tiga kali dengan 5 tanaman tiap ulangan. Analisis data pengamatan menggunakan analisis sidik ragam. Apabila ditemukan beda nyata diantara perlakuan maka dilanjutkan dengan uji Duncan’s Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa perlakuan nutrisi dengan beda komposisi serta tingkat dosis berpengaruh terhadap sifat fisiologis tanaman terong lokal buton seperti tinggi tanaman, kandungan klorofil, aktivitas nitrat reduktase dan nisbah luas daun. Secara keseluruhan, perlakuan nutrisi 3 Fe lebih baik dibandingkan dengan perlakuan nutrisi lainnya, yang disebabkan oleh tanaman terong lokal buton masih toleran terhadap penambahan perlakuan Fe.
