Abstract

Pertumbuhan bibit kakao yang baik di pembibitan sangat ditentukan oleh ketersediaan pupuk. Pemupukan dapat menggunakan pupuk organik maupun anorganik. Penggabungan kedua jenis pupuk tersebut diharapkan dapat meningkatkan pertumbuhan bibit kakao. Tujuan penelitian ini untuk mengetahui pengaruh pemberian dosis pupuk NPK dan bokashi daun gamal terhadap pertumbuhan bibit kakao (Theobroma cacao L.). Penelitian ini menggunakan Rancangan Acak Kelompok dengan analisis Faktorial 4x4 = 16 kombinasi dengan ulangan sebanyak 3 kali. Faktor  pertama adalah bokashi daun gamal (G)  terdiri dari 4 taraf, yaitu : B0 : tanpa perlakuan ( kontrol ), B1 : 75 g/polybag, B2 : 100 g/polybag, B3 : 125 g/polybag. Faktor kedua adalah pupuk NPK Mutiara (F) yang terdiri dari 4 taraf, yaitu : M0 : tanpa perlakuan (kontrol), M1 : 4 g/polybag, M2 : 8 g/polybag, M3 : 12 g/polybag. Interaksi kedua perlakuan yaitu bokashi daun gamal dan NPK Mutiara memberikan pengaruh yang sangat nyata terhadap pertumbuhan tinggi tanaman dan diameter batang dengan perlakuan terbaik yaitu B2M3 100 g/polybag dan 12 g/polybag sedangkan jumlah daun dengan perlakuan terbaik yaituB3M3 120 g/polybag dan 12 g/polybag

Abstract

Row spacing treatment had no significant effect on all parameters pengamatan.Pada age of 90 days after planting the average weight of the fresh fruit crop was obtained in treatment j2 highest ie 83.30 g, while the average weight of the fresh fruit crop obtained at the lowest possible j3 treatment of 75 , 49 g.Perlakuan extract of petals gods were not significantly affected all parameters pengamatan.Pada age of 90 days after planting the average weight of the fresh fruit crop was obtained in treatment d1 highest ie 83.98 g, while the average weight of the fresh fruit crop lowest was obtained in treatment that is 77.52 g.Interaksi d0 between the treatment plant spacing and crown god leaf extract had no significant effect on all parameters of observation. At the age of 90 days after planting the average percentage of disease were highest in j2d2 treatment combination that is 65.64% while the average percentage of the lowest in disease treatment combination j2d0 yaitu 51.72%. This research was conducted by randomized block design factorial 4 x 3 with three replications. The first factor is a spacing (A) which consists of three levels ie; j1 (60 x 60 cm), j2 (60 x 70 cm) and j3 (60 x 80 cm). The second factor is the extract of leaves of the gods crown (D), which consists of four levels ie; d0 (control), d1 (2 ml / liter of water), d2 (4 ml / liter of water) and d3 (6 ml / liter of water).

Abstract

Effect of Concentration and Interval Pseudomonas Fluorescens Biological Agents In Inhibiting the disease Growth purple patches Plants Onion (Allium ascalonicum L). This study aims to determine the effect of concentration and interval administration Pseudomonas fluorescens agents in inhibiting the development of spot disease purple onion crop. This research was conducted in the District of Samarinda Seberang, Samarinda, East Kalimantan using a randomized block design (RBD) with 5 treatments and 3 replications. The first factor is the concentration of Pseodomonas fluorencens with 5 levels: p0 = control, p1 = 5 ml / liter of water / plant, p2 = 10 ml / liter of water / plant, p3 = 15 ml / liter of water / plant, p4 = 20 ml / liter water / plant. While the second factor is the interval Pseodomonas fluorencens with 3 levels: i1 = 1 week, 1 x application until the age of 60 days, i2 = 2 weeks, 1 x application until the age of 60 days, i3 = 3 week 1 x application to the age of 60 days. Observation frequency and intensity showed no symptoms of disease purple spots, results of analysis of variance showed that the Pseudomonas Fluorescens Biological Agents (P) very significant effect on plant height increment 6 WAP. Further significant effect on the number of bulbs and tuber weight. the influence of the interval (I) had no significant effect on plant height parameter 3 WAP, 6 WAP and WAP, number of tillers, tuber number and weight of tubers. Results of analysis of variance showed that the interaction of Pseudomonas Fluorescens Biological Agents and Interval Giving. no real effect on plant height parameter 3 WAP, 6 WAP and 9 WAP, number of tillers, tuber number and weight of tubers.

Abstract

Identification of Types and Levels of Pests Attack on Palm Plantation Seedlings (Elaeis guineensis Jacq) at PT. Sentosa Kalimantan Jaya, Berau District East Kalimantan Province. Under the guidance of Iin Arsensi and Purwati. This study aims to determine the types of pests that attack oil palm seedlings, the frequency and intensity of oil palm pest attack on the Main Nursery stage nursery. The research was arranged in Survey method, determining 5 research plots in one block diagonally by marking on each plot with plastic marker of seeds, so obtained 15 research plots contained in 3 block that is block J, I and D. Each research plot consists of 30 Oil palm seedlings so that the number of observed 450 seeds of oil palm. The results showed that the types of pests that attack the oil palm seedlings in Main Nursery are Tungau (Tetranychus piercei), Adoretus compressus Beetle, and Locusta migratoria manilensis (Locusta migratoria manilensis); Block Frequency A pest attack in the category of minor attacks is 51.33%, 24% attack, while the intensity of pest attacks is a mild attack category; Frequency of Block I attack of pests in light attack category is 49,33%, moderate attack 37,33%, heavy attack 2%, while intensity of pest attack moderate attack category; Frequency of Block D attack of pest in light attack category is 41,3%, moderate attack 41,3%, severe attack 7,3%, while intensity of pest attack moderate attack category;
