Abstract

The aims of this research is to get the best concentration of cow urine as liquid organic fertilizer on rubber seed growth, to get the best fermentation time for cow urine as liquid organic fertilizer on the growth of rubber seedlings, and get the best interaction between concentration and cow urine fermentation as liquid organic fertilizer on the growth of rubber seedlings. The experiment was conducted in teaching farm of State Polytechnic of Lampung from January 2016 until June 2016. The treatments arranged in Randomized Block Design (RBD) with the factorial pattern consisting of two factors. The first factor was the concentration of cow urine, consisting of four levels: 15 cc.l-1, 30 cc.l-1, 45 cc.l-1 and 60 cc.l-1. The second factor was the duration of cow urine fermentation, consisting of five levels: 0 day, 7 day, 14 day, 21 day and 28 day. Rubber seedlings were used as plant indicator. Observations included plant height, number of petiole, stem diameter, stem girth, and dry weight of biomass. The results showed that the treatment of cow urine concentration had significant effect on plant height and number of petiole, but very significant effect on stem diameter, stem girth and dry weight of biomass. Likewise, the treatment of cow urine fermentation has significant effect on all observed variables except on the dry weight of biomass has a very significant effect. The interaction between treatment of cow urine concentration and cow urine fermentation did not significantly affect all variables except on dry weight of biomass had significant effect, i.e. cow urine concentration treatment of 45 cc.l-1 and fermentation of cow urine for 28 days resulted in dry weight of biomass higher rubber seedlings.   Keywords: cow urine, fermentation, rubber seedlingsPermalink: http://jurnal.polinela.ac.id/index.php/AIP/article/view/651

Abstract

One of the disadvantages of oil palm development is the limitedness of fertile soil. A constraint faced by both big plantation and small holders is the high cost of crop maintenance. Around 60% of the total crop maintenance is used for fertilizing the crop. This study aims at finding out phosphate absorbtion and the growth of oil palm seedling with the addition of Arbuscullar Mycorrhizal Fungi (AMF) and different dosages of phosphate fertilizer. A factorial Complete Randomized Design with three replications has been used. The first factor was the addition of AMF consisting of three levels: M0=0 g AMF polybag-1, M1=5 g AMF polybag -1, and M2 = 10 g AMF polybag -1. The second factor was the addition of four levels of phosphate using TCP-36: P0= 0 g TCP-36 polybag-1, P =15 g TCP-36 polybag-1, P2=30 g TCP-36 polybag-1, and P3=45 g TCP-36 polybag-1. Results showed that the Application of 10 g AMF polybag-1was able to increase P-absorbtion and the growth of oil palm seeding such as fresh crown weight, dry crown weight, fresh root weight, dry and root weight. Application of 45 g TCP-36 polybag -1was able to increase the growth such as plant height, dry crown weight, fresh root weight, and dry root weight.
