Abstract

Mentimun adalah salah satu keluarga Cucurbitaceae yang memiliki nilai ekonomi penting. Bibit berkualitas adalah bibit yang kuat, berdaun hijau, sehat dan memiliki perakaran yang baik. Tujuan penelitian ini adalah untuk mengetahui komposisi media yang tepat untuk pertumbuhan bibit mentimun. Penelitian ini dilaksanakan di Dramaga Bogor pada tahun 2013. Percobaan disusun dalam Rancangan Acak Kelompok dengan empat ulangan dan tujuh perlakuan. Perlakuan yang diberikan adalah vermikompos, arang sekam, pupuk organik granul, vermikompos-arang sekam, vermikompos-pupuk organik granul,arang sekam-pupuk organik granul, vermikompos- arang sekam- pupuk organik granul. Hasil penelitian menunjukkan bahwa semua karakter pengamatan (perkecambahan biji, tinggi tanaman, jumlah daun, luas daun, panjang akar, volume akar, rasio tajuk akar) berbeda nyata. Bobot basah tajuk  tertinggi diperoleh dari vermikompos-arang sekam (25,16 g), diikuti oleh vermikompos (24,70 g), vermikompos ? arang sekam- pupuk organik granul(16,60 g), arang sekam (12,28 g), arang sekam- butiran pupuk organik (7,47 g), vermikompos- pupuk organik granul (2,04 g) dan pupuk organikgranul (0 g). Sedangkan bobot basah akar tertinggi diperoleh dari vermikompos-arang sekam-pupuk organik granul(2,72 g), diikuti oleh arang sekam-vermikompos (2,43 g), vermikompos (2,43 g), arang sekam (1,37 g), vermikompos-pupuk organik granul (1,07 g), arang sekam ? pupuk organik granul (0,23 g), dan pupuk organik granul (0 g). Secara umum dapat dilihat bahwa media pembibitan mentimun akan memberikan pertumbuhan yang baik jika kita menggunakan vermikompos sebagai komponen utama atau campuran.

Abstract

The increasing popularity of leaf and fruit of African nightshade as vegetables in Indonesia stimulates farmers to harvest both leaf and fruit from single plant alternately; the yield is presumably affected by fertilizer rate, e.g., nitrogen. The present study aimed to evaluate such hypothesis through evaluation of plant production, N absorption, and its status. Seedlings were treated with five N levels, i.e., 0, 90, 180, 270, and 360 kg/ha in Leuwikopo Experimental Farm, IPB Bogor, Indonesia. The results revealed that leaf and fruit productions were sensitive to nitrogen level. Leaf and fruit productions had quadratic correlation to N levels, i.e., r 2=0.9671 and r 2=0.9483 with optimum dosages as 304.8 kg/ha and 336.5 kg/ha, respectively. Proper N application is important for both leaf and fruit productions because nitrate level in leaf had quadratic relationship (r 2=0.5264) and it has a linear relationship in fruit production (r2=0.9587) by increasing N level from 90 to 360 kg N/ha. From the total fresh mass leaves and fruits harvested, the optimum N for the best alternate harvesting was 271.1 kg/ha (r 2=0.9644).

Abstract

Potassium (K) is required in a large amount for plant growth and production of most fruit crops, including pineapple. However, excess application may decrease its growth and production. Therefore, fertilizer application must be site specifi c, based on soil nutrient status and plant requirements. The aims of the research were (1) to determine the soil K nutritional status of pineapple and (2) to determine the optimum dosage of K fertilization for pineapple grown in Sawah Baru, Darmaga, Bogor. The research was conducted using split plot randomized block design with fi ve soil K status as main plots i.e. 0, 70, 140, 210, and 280 kg K2O ha-1 representing status levels of very low, low, moderate, high, and very high, respectively. The sub plot was dosage of K fertilizer i.e. 0, 200, 400, 600, and 800 kg K2O ha-1. The result of the research showed that plant growth and production of pineapple were improved by soil K nutrient status and dosage of K application. The level of soil K nutrient availability was classifi ed into low (<14 ppm K2O), medium (14-50 ppm K2O), and high (>50 ppm K2O). Potassium fertilizer is recommended for the soil with low soil K status of 634 kg K2O ha-1 .

Abstract

Spray hose is a micro-irrigation system using perforated hose as for micro irrigation. Shallot conventional cultivation requires lots of water and labor man days therefore is more efficient. Shallot cultivation system needs to be developed to increase yield and to reduce production cost. This research was conducted to compare conventional cultivation methods with using Spray hose and polyethylene mulch for shallot production. This research was conducted in a hydromorphic alluvial soil type at the Center for Tropical Horticulture Studies Field Station in Kersana, Brebes, Central Java (S 6 o, 55’, 20.536”; E 108o, 51”, 50618”) from May to July 2016. The experiment was arranged in a randomized complete block design (RCBD) with a single factor and three levels of planting system, i.e. conventional ‘Surjan’ system without mulch, one line spray hose with mulch, and two lines spray hose with mulch, with five replications. The result showed that shallots production using of polyethylene mulch and two-line spray hose had higher yields than the conventional method. In addition, this system is more efficient in terms of labor requirement. Cost Revenue Analysis shows that conventional cultivation R/C ratio was 1.72, one-line spray hose R/C ratio was 1.92, while two-line spray hose was 2.26. This study demonstrated that the use of polyethylene mulch combined with two-line spray hose significantly improved shallot growth and increased bulb production, and more cost efficient.Keywords: R/C ratio, micro irrigation, labor, ‘Surjan’ system, soil drench, fertilizerConclusionIrrigation of shallot with two-line spray hose resulted in a better crop growth and a higher yield than conventional planting system and one-line spray hose for polyethylene mulched shallot.  Conventional planting system using more water and labor requirement than the two other treatments.

Abstract

Fertigation with drip irrigation is one of the technologies to solve fertilization and irrigation problems in chilli pepper production using polyethylene mulch. Potassium (K) is one of the important macro nutrients that affect plant growth and development due to its roles in the biochemical and the biophysical processes in plants. The objective of this study was to determine the best sources and the optimum rates of potassium for drip irrigated polyethylene mulched chilli pepper field production. The study was conducted in January until July 2018 at Tajur Experimental Farm, Center for Tropical Horticulture Study, Bogor Agricultural University. The experimental design was a split plot with the K sources (KCl, ZK, NPK) as main plots and K rates that consisted of five levels (0, 68, 136, 204, 272 kg K2O.  ha-1) as sub-plots. The results showed that the best optimum rate of K to produce fruit is 101.11 kg K2O.ha-1 with a maximum yield of 2.26 t.ha-1. Chilli crops fertilized with NPK and KCl had the greatest fruit weight per plant, fruit weight per plot, and fruit weight per hectare.
