Tissue culture plugs of Aglaonema `Cory', `Maria', and `Silver Queen' and Dieffenbachia `Panther', `Snowflake', and `Sport Lynn' were potted singly in 15-cm pots and grown in a shaded greenhouse under a photosynthetic irradiance (PI) of 100 mmol·m–2·s–1. Eight months after potting, 27 plants of each cultivar were placed in nine interior evaluation rooms under three different PI levels (three rooms per level): 4, 8, and 16 mmol·m–2·s–1. In addition, three plants of each cultivar were maintained in the original greenhouse for the duration of the experiment. Number of leaves, plant height and width were monitored monthly. Recently matured leaves were removed at 3-month intervals for 9 months for determination of fresh and dry weight, leaf area, and percentage leaf variegation. Variegated leaf area was assessed using digitized leaf images. Interior PI levels affected growth parameters, but the degree of response was cultivar-dependent. Smallest leaves developed on plants grown under 4 mmol·m–2·s–1 and largest leaves developed under 16 mmol·m–2·s–1. Leaf area of Dieffenbachia `Sport Lynn' showed the greatest response and Aglaonema `Maria' the least response to PI levels. Percentage leaf variegation of Dieffenbachia `Snowflake' was least affected and Dieffenbachia `Sport Lynn' was most affected by PI levels. Fresh leaf weight of unit area decreased as PI levels decreased from 16 to 4 mmol·m–2·s–1, however, the decrease in unit area was most pronounced in cultivars that maintained the highest quality ratings. Based on the results of this study, Aglaonema `Maria' and Dieffenbachia `Snowflake' had the most satisfactory interior performance within their respective genera.

The objective of this study was to investigate the growth parameters and plant biomass of tomato (Solanum lycopesicum) evaluated under different levels of boric acid, major source of boron. The treatments were; Normal nutrient solution (control, boric acid conc. = 0.000308 g l-1); nutrient solution in which the concentration of boric acid increased by the factor of 5 (boric acid x5, boric acid conc. = 0.00154 g l-1); and nutrient solution in which the concentration of boric acid was increased by the factor of 10 (boric acidx10, boric acid conc. = 0.00308 g l-1). Morphological attributes determined were shoot height, number of leaves, leaf area, shoot, leaf and root fresh and dry weight, and growth indices. Shoot height, number of leaves, leaf area, shoot, leaf and root fresh and dry weight, and growth indices in the seedlings treated with boric acid increased by factor of 10 (boric acid x10)were greater than other treatments. It can be concluded that nutrient solution of boric acid increased by a factor of ten improve the growth parameters and plant biomass of tomato.

SummaryEnhancement of the resistance level in plants by rhizobacteria has been proven in several pathosystems. This study investigated the ability of four rhizobacteria strains (Pseudomonas putida BTP1 and Bacillus subtilis Bs2500, Bs2504 and Bs2508) to promote the growth in three barley genotypes and protect them against Cochliobolus sativus. Our results demonstrated that all tested rhizobacteria strains had a protective effect on barley genotypes Arabi Abiad, Banteng and WI2291. However, P. putida BTP1 and B. subtilis Bs2508 strains were the most effective as they reduced disease incidence by 53 and 38% (mean effect), respectively. On the other hand, there were significant differences among the rhizobacteria-treated genotypes on plant growth parameters, such as wet weight, dry weight, plant height and number of leaves. Pseudomonas putida BTP1 strain was the most effective as it significantly increased plant growth by 15-32%. In addition, the susceptible genotypes Arabi Abiad and WI2291 were the most responsive to rhizobacteria. This means that these genotypes have a high potential for increase of their resistance against the pathogen and enhancement of plant growth after the application of rhizobacteria. Consequently, barley seed treatment with the tested rhizobacteria could be considered as an effective biocontrol method against C. sativus.

SUMMARYAn experiment has been carried out in order to study the behaviour under mineral deficiency of three sunflower genotypes, a population variety (Oro 9) and two hybrids (Mirasol and Albena). Sunflower seedlings were submitted to five treatments: N deficiency (N0), P deficiency (P0), K deficiency (K0), N and K deficiency (N0K0) and a control. Plants were harvested when they reached 3-4 true pairs of leaves. Growth parameters measured (height, total leaf area, root length, root and shoot dry mater) were all significantly reduced by mineral deficiency. Leaf area was most reduced by N0 (-61%) and P0 (-56%). Total dry matter was most affected by N0 (-63%) and by N0K0 (-66%). Genotype comparisons showed that Oro 9 had the highest shoot dry matter while Albena had the lowest root dry matter. Effect of mineral deficiency on content and partitioning of N, P, K, Ca and Na was significant and varied according to treatments and among plant parts. Shoot dry weight was significantly correlated with root N content (r2=0.81) and root K content (r2=-0.61) for N0 and K0.

The paitan plant contains allelopathic compounds for other plants so that the utilize of paitan plant as a source of liquid organic fertilizer (LOF) has not been widely applied. This research aimed to study the interaction between LOF dosage and appropriate application method of LOF to increase the growth of kailan plants. The research conducted at experimental garden of UIN Bandung from June-August 2016. The experimental design was a completely randomized design with two factors and replicated four times. The first factor was application methods (A), i.e. a1=direct application to the soil, and a2= spraying. The second factor was LOF dosage (T), i.e. t0: 0 ml plant-1, t1: 20 ml plant-1, t2: 40 ml plant-1, t3: 60 ml plant-1, t4: 80 ml plant-1. The growth parameters observed i.e. plant height (14, 21, 28, 35 and 42 Day after Transplanting (DAT)), leaf area 42 DAT, plant dry weight 42 DAT, and plant fresh weight 42 DAT. The data then analyzed with analysis of variance at a significant level of 5%. If the analysis of variance was significant, the Duncan multiple range test was used at α=5%. The research results showed there was no interaction between method of application with a various dosage of paitan LOF to all of the growth parameters. The application paitan LOF showed similar growth in terms of plant height, leaf area, plant dry, and plant fresh weight. The application method of paitan LOF direct to the soil or spraying to leaves can not increase kailan plant growth.

Vegetables form major part of human dietary/nutritional needs. It provides the necessary vitamins and minerals as well as antioxidants to boost immunity. Different vegetables however have different benefits and require different growing conditions. This study investigated the effect of two growing conditions (Screen-house and open field) and soil amendments; Mexican sunflower compost (MSC; applied at 0, 5, 10 t/ha) and NPK 15:15:15 (applied at 0, 50 and 100 kg N/ha) on the growth performance, yield, and nutritional quality of five selected vegetables (Amaranthus cruentus, Celosia. argentea, Solanum macrocarpon, Solanum nigrum and Solanum incanum). Each treatment was replicated three times and experiment arranged in completely randomized design, Compost was applied a week before seed sowing vegetables grown in the screen-house generally performed better than the open field in terms of leaf area and chlorophyll content. The response however varied based on the vegetable and the soil amendments. Solanum species, performed better than Amaranthus under screen-house than open field. Chlorophyll in the leaf responded positively to NPK fertilizer under screen-house conditions while growth parameters such as plant height, stem girth, number of leaves under screen-house and field conditions varied depending on the vegetables. The number of leaves and leaf area increased with soil amendments. Moisture, crude protein and ash contents were reduced under open field compared to screen-house. The zinc and iron contents of the vegetable leaves showed that addition of compost was superior to NPK and screen-house better than open field. It can be concluded that vegetables grown in the screen-house performed better in their respective growth parameters than vegetables are grown under the open field.

Abstract Rice plants (Oryza sativa) are a significant food crop. Tobacco plants (Nicotiana tabacum) can be beneficial and affect growth due to allelochemical content. The srudy aims to determine the effect of tobacco extract (N. tabacum) on the growth and yield of rice (O. sativa) Inpari-32 variety. The study method used the RBD as an experimental design. Three treatments with different concentrations of tobacco extract and one control with three replications. Growth variables were observed: growth rate, plant height, number of tillers, number of leaves, shoot and root dry weight, flowering age, and phytohormones. Observations of the harvest stage include the weight of stover, number of panicle seeds, the total number of tillers, weight of 1000 seeds, the ratio of the weight of filled grain, and productivity (tons/ha). The results showed that although not significant, tobacco extract treatment increased the number of tillers and leaves, the content of phytohormon IAA in the vegetative phase, the content of GA3 in the generative phase, shoot-root ratio, number of tillers, and accelerated flowering age. The implication of tobacco extract positively affects the plant growth variable and accelerated flowering age of rice variety (O. sativa) Inpari 32.

<p>Tanaman nilam tumbuh dan berproduksi dengan baik pada daerah dengan curah hujan relatif tinggi dan merata sepanjang tahun. Tanaman dalam kondisi kekurangan air terus menerus akan mengalami strcs air dan berpengaruh terhadap proses fisiologis, menurunkan permukaan trans- pirasi, luas daun menurun, dan mempercepat dcfiidrasi protoplasma. Penelitian pengaruh ketersediaan air terhadap petumbuhan dan produksi 2 (dua) klon nilam dilakukan di rumah kaca Instalasi Penelitian Cimanggu, Balittro Bogor mulai bulan Nopember 1999 sampai dengan Mei 2000. Penelitian ini betujuan untuk mengetahui pengaruh ketersediaan air terhadap partumbuhan dan produksi dua klon nilam (klon Sidikalang dan klon Situak) sekaligus diamati pengaruhnya terhadap kadar dan kualitas minyak nilam (rendemen, warna dan kandungan patchouly alkohol). Percobaan dilakukan dalam polibag menggunakan tanah kering jenis latosol Cimanggu Bogor yang diaduk dengan pupuk kandang sapi (3:1) sebanyak 10 kg/polibag disusun menggunakan rancangan factorial (dua faktor) dalam rancangan acak lengkap (RAL), diulang 3 kali. Ukuran plot 8 polibag/ perlakuan. Faktor pertama : klon nilam terdiri dari 2 jenis (K) yaitu : Kl = klon Sidikalang dan K2 = klon Situak. Faktor kedua: tingkat ketersediaan air (A) 4 taraf yaitu Al = 25% kapasitas lapang, A2 = 50% kapasitas lapang, A3 = 75% kapasitas lapang, dan A4 = 100 % kapasitas lapang. Peubah yang diamati meliputi persentase tumbuh tunas, tinggi tanaman, luas daun, bobot daun basah dan bobot daun kering, kadar minyak digambarkan dari rendemen dan kualitas minyak (wana dan kandungan patchouly alkohol). Hasil penelitian menunjukkan bahwa untuk jumlah tunas tidak ada interaksi antara tingkat ketersediaan air dan klon yang diuji, tetapi untuk jumlah daun ada interaksi. Tingkat pemberian air 75% kapasitas lapang (KL) secara keseluruhan memberikan pertumbuhan optimum bagi kedua klon, kecuali untuk parameter jumlah daun. Pada klon Situak. tingkat pemberian air 100% KL yang memberikan jumlah daun terbanyak. Perlakuan ketersediaan air 100% KL pada klon Sidikalang memberikan bobot daun kering tetinggi dibanding perlakuan lainnya, sedang untuk klon Situak, ketersediaan air pada taraf 75% KL memberikan bobot daun kering tetinggi. Rendemen minyak klon Situak dengan tingkat ketersediaan air 25% KL tertinggi (4.0%) dengan wana minyak kuning muda tcrang, diikuti tingkat 50% KL (3.0%) dengan wana minyak kusam/kemh. Kandungan patchouly alkohol klon Situak rata-rata (30%) lebih baik daripada klon Sidikalang, diperoleh dari perlakuan ketersediaan air 25% KL. Dapat disimpulkan bahwa untuk memperoleh petumbuhan dan produksi yang tinggi, ketersediaan air dalam tanah diperlukan antara 75 - 100% KL. Namun, untuk mendapatkan kandungan patchouly alkohol tinggi ketersediaan air yang dibutuhkan lebih rendah yaitu 25 % - 50%) KL.</p><p>Kata kunci: Nilam, Pogostemon cablin, ketersediaan air, petumbuhan, produksi</p><p> </p><p><strong>ABSTRACT</strong></p><p><strong>The effect of water availability the growth and production of two patchouly clones </strong></p><p>Patchouly plant grows and produces very well in the area with high and everly rain fall through the year. Plants with continuous shortage of water would face water stress and affect physiologis process, transpiration surface, leaf area and protoplasmic dehydration. Several levels of water needs were tested in this experiment, which was carried out in a glass house of Cimanggu Installation, Indonesian Spice and Medicinal Crops Research Institute, Bogor, rom November 1999 to May 2000. The objective was to find out the effect of water availability on two clones of patchouly growth, production and oil content (rendement, colour and patchouly alcohol). The experiment was conducted in polybags using Cimanggu Latosol soil mixed with cow dung (3:1), 10 kg/polybag, arranged in a factorially completely random design with 3 replications. Plot size was 8 polybag/treatment. The first factor was two clones of patchouly : K, = Sidikalang and K2 = Situak. The second factor was 4 levels of water availability: 2J% (A,), 50% (A2). 75% (A,), and 100% (A,) ield capacity (FC). Variables observed were percentage of shoot growth, plant height, leaf area, fresh weight and dry weight, oil content (rendement, colour and patchouly alcohol). The result showed that there was no interaction between the two factors for number of shoots. Clone of Sidikalang had higher plant height than that of Situak. The water availability of 75% (FC) gave optimum growth for the two clones, except the number of leaves. For Situak the water avaibility of 100% (FC) gave the highest number of leaves. For Sidikalang the water availability of 100% gave the highest dry weight of leaves. Oil rendement for Situak with 25% FC was the highest (4.0) with bright yellow colour. The content of patchouly alcohol for Situak was higher than that of Sidikalang (30%). Therefore, it can be concluded that to obtain the optimum growth and the higest production it needed 75 - 100% (FC) water availability, while for high patchouly alcohol content, it needed buzer the water availability, i.e. 25-50% (FC).</p><p>Key words: Patchouli, Pogostemon cablin, water level, growth, production</p>
