Abstract

Penelitian ini bertujuan untuk mengetahui jarak tanam dan pemberian dolomite di Lahan Pasang Surut. Penelitian ini dilaksanakan lahan pasang surut yang ada di Desa Sei Ular , Kecamatan Secanggang, Kabupaten Langkat dengan ketinggian tempat ± 1 m dpl selama 4 bulan Juni - September 2014). Tujuan jangka panjang dari penelitian ini adalah dapat kiranya ditentukan diharapkan dapat menekan Na+ dalam tanah, sehingga dapat pH Tanah menjadi sesuai bagi tanaman kacang tanah. Penelitian dilakukan dengan menggunakan rancangan acak kelompok (RAK) Faktorial terdiri dari dua faktor yaitu : Faktor pertama : Variasi Jarak Tanam (J) yakni :J0 = Jarak Tanam 20 cm x 20 cm, J1 = Jarak Tanam 30 cm x 20 cm J2 = Jarak Tanam 40 cm x 20 cm. Faktor Kedua : Pupuk Dolomit (D), yakni D0 = 0/plot, D1 = 3 ton/ha, D2= 6 ton/ha D3= 9 ton/ha. Penelitian ini diharapkan dapat memberikan hasil produksi yang nyata . Hasil penelitian menunjukkan bahwa pemberian perlakuan jarak tanam dan pupuk dolomite pada tanaman kacang tanah memberikan hasil yang nyata pada beberapa pengamatan. Pemberian pupuk dolomite mampu memberikan tekanan atau mengurangi kadar Na di lahan pasang surut.

Abstract

Introduction: The research was aimed to obtain an appropriate dose of cow manure waste, calcium oxide lime, and interactions in increasing the growth and yield of cowpea. Material and Methods: The research was conducted in Secanggang Village, Secanggang Subdistrict, Langkat District in June until September 2017. The research was conducted using the Randomized Block Design Factorial, the first factor (cow manure waste) dose of L0= 0 ton ha-1; L1= 10 ton ha-1; L2= 20 ton ha-1. The second factor (calcium oxide lime) dose of K0= 0 ton ha-1; K1= 3 ton ha-1; K2= 6 ton ha-1; and K3= 9 ton ha-1. Data were analyzed using the F and followed by DMRT at level 5% using IBM SPSS Statistics v.20 software. Results: The cow manure waste dosages of 10 until 20 ton.ha-1 significantly increased the plant height at 4 Weeks After Planting (WAP) and yield.plot-1 of cowpea ranged from 2.14 to 2.50% and 13.00 to 15.98%, respectively and the dose of 20 ton.ha-1 significantly increased the yield.sample-1 of 17.44% compared to untreated. The application of calcium oxide lime at the dose of 9 ton.ha-1 significantly increased the plant height of cowpea at 4 WAP of 2.46%, and the dose of 6 until 9 ton.ha-1 significantly increased the yield.sample-1 and yield.plot-1. However the highest was found in the dosage 6 ton.ha-1 of 13.51% and 20.16% compared to untreated. The interaction of cow manure waste with calcium oxide lime were not significant effect on growth and yield of cowpea.

Abstract

Introduction: This research was determined the growth response of cocoa (Theobroma cacao L.) in N-fertilizer and sugarcane bagasse compost. Materials and Methods: This research was conducted at agricultural area of ​​Sejati Street, Sari Rejo Village, Medan Polonia Sub-District, Medan. This research was conducted from August until December 2015. This research used therandomized block design in factorial. The first factor was N-fertilizer with 4 rates, 0 g.polybag-1 (P0), 2 g.polybag-1 (P1), 4 g.polybag-1 (P2),and 6 g.polybag-1 (P3). The second factor was the provision of sugarcane bagasse compost with 4 rates, 0 g.polybag-1 (K0), 2 g.polybag-1 (K1), 4 g.polybag-1 (K2) and 6 g.polybag-1 (K3). The observed data were analyzed by the F-test, and continued with the DMRT at level of 5%. Results: Composting bagase significantly affected the leaf area of cocoa seedling at 2 and 4 weeks after planting. The application of N-fertilizer had significant affected the number of leaves for cocoa seedling. The interaction of P2K2 (6 g.polybag-1 N and 4 g.polybag-1 of bagasse compost) showed the highest fresh- and dry-weight of cocoa seedling compared to other interactions, although the effect was not significant.

Abstract

Penelitian ini bertujuan untuk mengkaji pemanfaatan pupuk kandang ayam dan pemberian pupuk kalium serta magnesium terhadap pertumbuhan jagung manis (Zea mays saccharata Sturt). Metode yang digunakan dalam penelitian ini adalah rancangan acak kelompok (RAK) Faktorial dengan tiga faktor. Faktor pertama yaitu pupuk kandang ayam (A) terdiri dari: A0= tanpa pupuk kandang ayam, A1= 10 ton/ha (100 g/polybag). Faktor kedua yaitu pupuk magnesium (D) terdiri dari: D0= 0 g/polybag, D1= 17 g/polybag. Faktor ketiga yaitu pupuk kalium (K), terdiri dari: K0= 0 KCl/ha, K1= 0,83 g/polybag, K2= 1,66 g/polybag, K3= 2,50 g/polybag. Hasil penelitian menunjukkan bahwa pemberian pupuk kandang ayam signifikan meningkatkan tinggi tanaman 4 dan 6 MST, bobot kering tajuk dan akar, bobot kering total, kandungan K dan Mg di daun, serapan hara K dan Mg pada tanaman jagung manis. Pemberian pupuk Mg (dolomit) signifikan meningkatkan bobot kering tajuk dan akar, bobot kering total, dan kandungan Mg di daun tanaman jagung manis. Interaksi pupuk kandang ayam dengan pupuk Mg berpengaruh tidak nyata terhadap semua parameter penelitian ini. Pemberian pupuk K (KCl) signifikan meningkatkan bobot kering tajuk, bobot kering total, dan kandungan K di daun tanaman jagung manis. Interaksi pupuk kandang ayam dengan pupuk K hanya berpengaruh nyata terhadap tinggi tanaman 2 MST. Interaksi pupuk Mg dengan K signifikan meningkatkan bobot kering tajuk dan bobot kering total tanaman jagung manis. Interaksi pupuk kandang ayam, pupuk Mg dan K signifikan meningkatkan bobot kering akar tertinggi pada interaksi A1D0K1 sebesar 20,93 g.

Introduction: The purpose of this study was to determine the response of tomato plants (Solanum licopersicum) to the administrationof liquid organic fertilizer cow urine and phosphorus fertilizers on andisol soil. Materials and Methods: This 'research' was carried out in October 2022 – January 2023 in Selayang village, Finish district, with an altitude of 28 meters above sea level. This study used a factorial randomized block design with 2 treatment factors. The firstfactor is cow urine liquid organic fertilizer with Symbol (A) which consists of 2 treatment levels, namely: A0 = (0 ml), A1 = ( 60 ml). The second factor was the application of phosphorus fertilizer symbol (P) which consisted of 4 treatment levels, namely: P0 (without fertilizer), P1 (125kg P/Ha ≈ ­­­­­­­­­­1,7gSP-36/polybag), P2 (250kg P/Ha ≈ 3,5 gSP-36/ polybag) dan P3 (375kg P/Ha ≈ 5,2 gSP-36/polybag). Results: The results showed that the treatment of cow urine liquid organic fertilizer (POC) had a very significant effect on the parameters of plant height aged 56 HST, yield and production of tomato plants with the best treatment found in A1 (60 ml). The aplication of phosphorus fertilizer had a significant effect on soil pH and available-P with the best treatment P1 (125kg P/Ha ≈ 1,7 g SP-36/polybag). The interaction of cow urine liquid organic fertilizer (POC) and phosphorus fertilizer had a very significant effect on the yield and production of tomato plants with the best combination treatment A1P1 (60 ml) (125kg P/Ha ≈ 1,7 g SP-36/polybag).

Abstract

Introduction: The purpose of this study was to determine the response of tomato plants (Solanum licopersicum) to the administrationof liquid organic fertilizer (poc) cow urine and phosphorus fertilizers on andisol soil. Materials and Methods: This research will be carried out in Selayang Village, Prestasi District, Langkat Regency, North Sumatra, from January to April 2023. This research used Liquid Organic Fertilizer (POC) and Chicken Manure with different doses. The design used was a Randomized Block Design (RBD) consisting of Liquid Organic Fertilizer Factors (POC) E0 = Without applying liquid organic fertilizer, E1 = 40ml/liter of water(4%), E2 =50ml/liter of water(5%) and Chicken Manure B0 = Without Chicken Manure, B1 = 100grams of Chicken Cage, B2 =200gram of Chicken Cage. The parameters observed in this study were plant height (cm), number of leaves (strands), stem diameter (mm), and leaf area (cm2). Results: The application of liquid organic fertilizer in oil palm nurseries had a significant effect on the number of leaves at 4 MST, 5 MST and stem diameter at 4 MST. The best treatment was at E1 =40ml/liter of water (4%). The application of chicken manure to oil palm nurseries did not significantly affect all parameters. The best treatment was found in treatment (B2 = 200grams of chicken coop. The interaction of liquid organic fertilizer D. grow and chicken manure had a significant effect on the number of leaves aged 4 WAP. The best treatment combination was found in treatment E2B1 (50 ml/liter of water (5%) (100 grams of chicken coop).
