Abstract

Shallot production and productivity of Indonesia is still low; thus, needs to be increased by providing biological organic fertilizers (POH) and growth regulators (ZPT). The research was carried out in the Covid-19 Pandemic Area from December 2019 to March 2020 in Talotenreng Village, Wajo Regency. The aim of this study was to determine the shallot (Allium ascalonicum L.) productivity by using POH and ZPT. Two experimental factors with the Randomized Block Design were used as method for this study. The first factor was the POH (P) concentration of 0 ml liter of water-1, 10 ml liter of water-1, 20 ml liter of water-1, and 30 liter of water-1. The second factor was the ZPT concentration (Z) of 0 ml liter of water-1, 1.0 ml liter of water-1, 1.5 ml liter of water-1, and 2.0 ml liter of water-1. The experimental results showed that the POH concentration significantly affected the weight of fresh blubs per plot and the concentration of growth regulators had a significant effect on the number of bulbs per plot and the productivity of shallots as much as 8.09 t ha-1.

Abstract

Water hyacinth is a type of plant that grows in freshwater environments. This plant is an ideal raw material to produce bokashi which increases the availability of soil nutrients. To maximize the function of the water hyacinth bokashi, a growth regulator is used to encourage plant upatake of soil nutrients. This study aimed to examine the single effect and interaction between water hyacinth bokashi (BHW) and plant growth regulators (PGR) on black rice. Data were analyzed with a factorial randomized block design. The first factor is WHB (B) 0 ha-1 and 2 t ha-1, while the second factor is PGR (Z) 0 ppm and 1.5 ppm. The results showed that the best effect of grain weight per hectare was treatment with WHB 2 t ha-1, PGR 1.5 ppm, and their interactions were 10.34 t ha-1; 11.09 t ha-1, and 12.16 t ha-1 harvested dry rice
