Abstract

Penelitian hasil ubi kayu (Mannihot esculenta Crantz.) terhadap perbedaan jenis pupuk bertujuan untuk mempelajari pengaruh perbedaan jenis pupuk terhadap hasil ubi kayu.Penelitian dirancang menggunakan Rancangan Acak Kelompok (RAK) dengan tiga perlakuan yang diulang sebanyak empat kali. Perlakuan tersebut adalah: A = tanpa pemupukan, B = 250 kg NPK/ha +150 kg urea/ha, dan C = 20 ton/ha bokashi kotoran sapi. Variabel pengamatanadalah: 1) Jumlah umbi/tanaman, 2) Bobot umbi/tanaman, dan 3)Produksi umbi/petak.Data hasil pengamatan dianalisis secara statistik menggunakan ANOVA dan Uji BNT 5%.Hasil penelitian menunjukkan bahwa perbedaan jenis pupuk berpengaruh terhadap hasil ubi kayu (bobot umbi/tanaman dan produksi umbi/petak). Bobot umbi/tanaman dan produksi umbi/petak tertinggi diperoleh pada pupuk bokashi kotoran sapi dengan dosis 20 ton/ha dan 250 kg NPK/ha + 150 kg urea/ha. Perlu penambahan pupuk pada lahan penelitian yang ditanami ubi kayu.

Abstract

ABSTRACT   This study aimed to find out the effects of several types of organic fertilizers on peanut’s yield. This study was conducted in the greenhouse environment using a randomized block design with of four treatments of organic fertilizer. Each treatment was repeated five times. Treatment A = without fertilizer; B = Liquid Organic Fertilizer Super Aci 4 cc / liter of water; C = Granular Organic matter 1000 kg / ha; and D = Humagrow 500 grams / ha. Observed variables included  1) plant dry weight, 2) numbers of pods , 3) numbers of empty pods, and 4) weight of pods.

Abstract

ABSTRACTThe effect mixing of chicken manure and clayed soils (soil colloids) into ex-mining soils (tailings) on soil chemical properties and growth of sweet corn plants were the objective of this study. Tailings and the clay soils were taken from Tatelu Village of Dimembe Subdistrict and from Paniki Mapanget Subdistrict, respectively. This field research was conducted in Tara-tara II Subdistrict Tomohon West, District of Tomohon. Soil analyses were conducted in Soil Chemistry and Soil Fertilizer and in Soil Physics and Soil Conservation Laboratory at Soil Department, Agriculture Faculty UNSRAT Manado. A completely randomized design consisting of 7 treatments in 4 replicates is utilized in experiment using a 30 kg polybags. The results showed that mixing of clay-textured soil and manure on tailings gave significant effect on soil cation exchange capacity, soil P-available, K-available, corn dry weights, and corn cob weights. However, mixing materials have no significant effect on pH, C-organic content, and total N-content. The best combination mixing of materials is 40 persent clay textured soil and 30 tons of chicken manure and tailings.Keywords: Tailings, Clay Textured Soil and Chicken Manure

Abstract

ABSTRACK This research was conducted to observe the changes of physical properties and responses of sweet corn (Zea mays saccharata Sturt.) planted on Tatelu's tailings soil. The reserch conducted at the UNSRAT Experimental Garden in Wailan Village, Tomohon City on July 2018 to February 2019. The research used Completely Randomized Design (CRD) as research methodology which consisted five treatments. The treaments were: A = 300 kg / ha of phonska fertilizer + 0 tons / ha of organic fertilizer, B = 300 kg / ha of phonska fertilizer + 50 tons / ha of goat manure, C = 300 kg / ha of phonska fertilizer + 40 tons / ha of fertilizer organic plus + 10 tons / ha goat manure, D = 300 kg / ha phonska fertilizer + 30 tons / ha organic fertilizer + 20 tons / ha goat manure, E = 300 kg / ha phonska fertilizer + 30 tons / ha organic fertilizer plus + 20 tons / ha of goat manure. Each treatment was repeated four times to obtain 20 experimental pots. Sweet corn plants as indicators. Parameters observed included: 1) Sweet corn cobs weight, 2) Oven dry weight of sweet corn plants 3) Analysis of soil physical properties after harvest: organic-C, Soil Pemeality and porosity. The field experiment used a polybag pot with a completely randomized design consisting of five treatments with four replications. The data obtained will be analyzed by variance. If F-count is greater than F-table (F count> F table), then the data will e analyzed with the smallest real difference test (BNT 5%). The results showed that the combination of organic matter in soil tailings had a significant effect on organic-C, porosity, and permeability, but it had no significant effect on cob weight, and plant dry weight, but tended to provide a greater value compared with no organic matter. Organic materials and plus organic materials tend to be better than goat manure to rehabilitate tailings.  Keywords: Rehabilitation of tailings, and kinds of organic materials.

Abstract

ABSTRACKThis study was to determine the state of soil chemical fertility in the soil planted withchilies (Capsicum annum L.) in Lowian village, Maesaan District, South Minahasa Regency, aswell as to support chili farming in Lowian village. This research was conducted in Lowianvillage, Maesaan District, South Minahasa Regency. Soil sampling was carried out in twolocations, namely at the top of the village and at the bottom of the village. Furthermore, theanalysis of soil chemical properties at the Laboratory of Chemistry and Soil Fertility, Facultyof Agriculture, Sam Ratulangi University, Manado. The research period starts from Septemberto October 2020. The results of the analysis of several soil chemical properties in chilicultivation in Lowian village, Maesaaan District show that soil acidity (soil pH) is in a slightlyacidic state (6.3 - 6.4), C-organic has a low to moderate content value (1.74). - 2.22), the valueof the cation exchange capacity (CEC) is in a low to moderate state (13.82 - 18.54), Nitrogennutrient content is low (0.14 - 0.19), Phosphorus nutrient content is in a low state (11.64 -12.45), and the nutrient content of Potassium is in a low state (13.32 - 20.11) In general, basedon the results of laboratory analysis, it was stated that the soil chemical fertility in Lowianvillage, Maesaaan District, was at a low level.Key words: Soil, chemical properties, chili plants
