Abstract

This research aims to determine the growth of turi plants on former gold mining land, by applying cow manure. This research was carried out at the BPDAS Palu Poso Permanent Nursery in the Tadulako University area. This research was carried out from April to November 2023. This research used a Completely Randomized Design (CRD) consisting of 4 treatments including P0= No Treatment, P1= 150 gr Manure P2= 200 gr Cow Manure P3= 250 gr Cow Manure. Each treatment was repeated 10 times so that there were 40 experimental units. The results of the analysis of variance showed that the growth of turi seedlings in ex-gold mining soil with the application of cow manure had a significant effect on the increase in height, diameter and number of leaves. The treatment that gave the best response was treatment P3= (250 gr of cow manure) with an average increase in height of 19.53 cm, an average increase in diameter of 0.72 mm, and an average increase in the number of leaves of 7.4 pieces.

Abstract

This research was carried out for 3 months, namely from March 2023 to June 2023, located at the BPDAS-HL Palu-Poso Permanent Nursery, this study used the Complete Randomized Design method consisting of 4 treatments, namely P0 = 0%, P1 = 20%, P2 = 30% and P3 = 30%. The four treatments were repeated seven times, bringing the total sample to 28 experimental units. The parameters observed are the increase in seedling height, stem diameter and number of leaves. The data analysis used is fingerprint analysis (F test) fingerprint analysis shows that the best treatment, it will be continued with further tests, namely the BNJ test level of 5%. The results showed that the concentration treatment of liquid organic fertilizer made from gamal leaves had a real influence on the increase in height, stem diameter and number of leaves in arabica coffee seedlings. The best treatment in this study was 40% concentration treatment (P3) with an average seedling height of 15.27 cm, an average seedling stem diameter of 3.17 mm and an average number of seedling leaves of 12.28 strands and the results of BNJ fingerprint analysis with an average height of 5.59 cm, number of leaves of 1.2 strands and stem diameter of 0.88 mm.

Abstract

The fulfillment of rattan needs in the future will continue to increase, and it is estimated that rattan sources from natural forests will not be able to provide sufficient quantities. Therefore, rattan development is still needed, especially in cultivating it on community land or in community nurseries. Rattan cultivation needs to be developed by procuring good and quality rattan seedlings, one form of effort in increasing the productivity of rattan stems is through maintenance so that to obtain quality seedlings, additional materials are needed in the media to provide nutrients that support plant growth. One of the organic fertilizers that plays a role in soil quality and plant growth is cow manure compost where this fertilizer is processed animal waste or cow manure that is given to the soil to improve soil fertility. This study provides information on the effect of giving various doses of cow manure on the growth of rattan stem seedlings (Calamus zollingeri Becc) in polybags so that it can be used as a guide in utilizing the cow manure optimally. This study used a completely randomized design (CRD) consisting of five treatments, P0 = soil without cow manure (control), P1 = 1000g soil + 200g cow manure, P2 = 1000g soil + 300g cow manure, P3 = 1000g soil + 400g cow manure, P4 = 1000g soil + 500g cow manure, Each treatment was repeated 10 times so that it required as many as (5x10) = 50 experimental seed units.

Abstract

The aim of this research was to determine the effect of various types of planting media on the growth of calliandra seedlings. This research was carried out in Wuasa Village, North Lore District, Poso Regency and was carried out for 7 months, namely from April to October 2021. The research method used a Completely Randomized Design (RAL) which consisted of 4 treatments, namely: PO = Land Without Fertilizer (control), P1 = Soil + Sand + Soil Liquid Fertilizer + Leaf Liquid Fertilizer, P2 = Soil + Sand + Solid Organic Fertilizer, P3 = Soil + Sand + Solid Organic Fertilizer + Soil Liquid Fertilizer + Leaf Liquid Fertilizer Each treatment was repeated as many times as ten times, so that a total of 40 experimental units were needed. The observational data was analyzed using analysis of variance (F) with the Least Significant Difference (BNT) test at a significance level of 5%. The results of the research showed that treatment with various types of planting media had a very significant effect on increasing the number of shoots, increasing height, increasing the number of leaves and stem diameter on the growth of calliandra calothyrsus Meissen seedlings. Soil+sand+solid organic fertilizer+soil liquid organic fertilizer+liquid organic leaf fertilizer (P3) is the best medium for the growth of calliandra mesh (Calliandra calothyrsusMeissen) seedlings, in all the variables observed.

Abstract

Coffea arabica plantations in Central Sulawesi are carried out on the Napu highland, where this area is dominated by ultisol or yellow red podzolic soils, which have problems of high soil acidity and low availability of macro nutrients. This study used a completely randomised design method consisting of four treatments namely; without organic fertilisers (control)/P0, Leucaena leucocephala leaf compost 3 Kg/tree (P1), Samanea saman leaf compost 3 Kg/tree (P2), Tithonia diversifolia leaf compost 3 Kg/tree (P3), Cow and goat manuire 3kg/tree (P4). The results showed that there were 10 species of Arbuscular Mycorrhizal Fungi (AMF) associated with Coffea arabica plants namely Glomus sp1, Glomus sp2, Glomus sp3, Glomus sp4, Acaulospora sp1, Acaulospora sp2, Acaulospora sp3, Gigaspora sp1, Gigaspora sp2 and Gigaspora sp3. Furthermore, the higher density of FMA spores was found in the treatment without organic fertiliser application/control (P0) which was 31 spores/10 g soil, compared to the treatment of Tithonia diversifolia leaf compost treatment (P3) with 11 spores/10 g soil, cow and goat manure treatment (P4) with 3 spores/10 g soil, and Samanea saman leaf compost treatment (P2) with 2 spores/10 g soil.  And in the Leucaena leucocephala leaf compost treatment (P1), no AMF spores were found. The difference in AMF spore density in the various organic fertiliser treatments mentioned above is related to the effect of improving soil chemical properties on the soil. The results of this study contribute to the understanding of the importance of soil amendments with organic fertilisers for the improvement of organic and sustainable arabica coffee production in the future.
