Saran
Penelitian lanjutan perlu dilakukan untuk memperoleh data yang lebih akurat. Dosis pemupukan K perlu ditingkatkan karena masih banyak respon linear dalam beberapa parameter yang diamati.

Lampiran 2 Cara perhitungan bobot
Bobot per bedeng Diketahui:
Jumlah total tanaman : 20 Jumlah tanaman hidup: 18
Bobot tanaman hidup : 4245.03 g Ditanya: Bobot per bedeng Perhitungan :
=jumlah total tanaman x Bobot tanaman hidup
total tanaman hidup= 20 x 4245.03g 18
= 4716.7 g (*Data yang tertulis di tabel adalah data rata-rata) Bobot per hektar
Diketahui:
Bobot per bedeng : 4716.7 g Luas bedeng : 7.5 m2 Ditanya : Bobot per hektar Perhitungan :
= Luas per hektar x Bobot per bedeng Luas bedeng
=10000 m2 x 4716.7 g 7.5 m2
