Abstract

ABSTRACTAnnona muricata L. is a kind of plant growing and fruiting perennially if the water  demond  is  apparently  sufficed.  A.  muricata  L.  seed  has  averagely  less germination power, however it can be improved by the induction. Coconut water is proved to induct that power because it contains some essences supporting seed growth: auxin, gibberellind and cytokinins. This research was carried out at 13rd January until25th   February in Physiology Laboratory of Biology Departement Unversity of Padang.This is a descriptive research which used six concentrates of coconut water are: 0%,20%, 40%, 60%, 80% and 100% with every concentrate is put on four plastic scuttles. The observation was held six week to find out days when seed started growing and amount of seed germinating. The result showed that germination in 60% appeared in19th      day.  The  writer  summarizes  that  coconut  water  dad  not  be  able  to  inductgermination of A. muricata seed. The result evidenced that from 120 seeds germination, there werw only 7 seeds started growing.

Abstract

Pseudomonad fluorescents (Pf) is a biological agent that has been reported to enhance the growth of many plants because it can produce plant growth substance (auxin, gibberellins, and cytokinins), phosphate solvent enzyme, and siderofor. Information about the frequency of Pf in improving plant growth is limited. This study aimed to investigate the effect of  biofertilizer applied frequency on upland rice growth. The study was conducted from October to December 2011 in the screenhouse and Laboratory of Biological Department, Padang  State University. This study is experimental and the design used was randomized block design with 6 treatments and 5 replications. The treatment is the frequency of Pf applied there are without Pf (control), once, twice, three times, four times and five times. Data were analyzed using ANOVA and further test DNMRT the real level of 5%. The result showed that application of biofertilizer able to increasethe number of tillers and biomass of upland rice. However, the frequency of Pf has no effect on plant height, number of tillers, the wet weight and plant biomass.Key words : Pseudomonad flourescen, frequency, upland rice, biofertilizer

Abstract

Long term period of using fertilizers is not beneficial for soil fertility due to decreasing soil organic matter content. Otherwise, the source of organic matter widely available as waste in the environment are not used optimally because the naturally decomposition quite long time. This problem can be overcome by utilizing various types of microbes, such as Trichoderma. This research conducted to determine the effect of organic fertilizer from the decomposition result of T. harzianum in enhancing growth of spinach plant. This study used a completely randomized design (CRD) with 6 treatments and 4 replications. The treatments were doses variation of decomposition of organic material; 0 g, 15 g, 30 g, 45 g, 60 g and 75 g. Data were analyzed with ANOVA and continued with Duncan New Multiple Range Test (DNMRT). The results showed that the application doses  of organic fertilizer from decomposition result influences height, number of leaves, leaf area, fresh weight and dry weight of spinach plants. Optimal dose for all growth is 45 grams/polybag.
