A pot experiment was conducted under rainfed condition to study the effect of water hyacinth compost on the morpho-physiological parameters of soybean (Glycine max L.) at the Teaching and Research Farm of Faculty of Agriculture and Veterinary Medicine, Imo State University, Owerri. The treatments were control (T1) 100g (T2), 150g (T3) and 200g (T4) of water hyacinth compost and replicated four times. The treatments were arranged in Complete Randomized Design (CRD). The parameters measured were plant height, number of leaves, leaf area (cm2), leaf area index, relative growth rate (RGR), Net assimilation rate (NAR), shoot dry weight(g), yield and yield components (Number of pods, pods weight, 100 seed weight). The results obtained indicated that T3 significantly produced highest plant height (57.6cm) compare to control. While it was observed that T4 (200g) significantly produced the highest number of leaves (233.25), leaf area (631.80cm2), shoot dry weight (15.445g), number of pods (129.75), pod weights (25.38g) seed weight (7.23g) and yield (0.72kg/ha) relative to control and other treatment levels. Root parameters were also significantly improved by the rates of water hyacinth application compared to control. It will be worthy to note that there was no nodulation perhaps that was why the yield was poor. The results showed that soybean growth can effectively be improved with incorporation of water hyacinth into soil.

<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>

Herbicide Drift

There have been anecdotal accounts of increased crop sensitivity due to herbicide drift followed by an in-crop herbicide. An experiment was conducted from 2005 to 2007 at Elora, Ridgetown, and Woodstock, Ontario, to determine the effects of simulated mesotrione drift followed by in-crop applications of glyphosate, imazethapyr, bentazon and glyphosate plus chlorimuron on glyphosate-resistant soybean [Glycine max (L.) Merr.] visual injury, plant height, plant density, shoot dry weight, and seed yield. As the rate of simulated mesotrione drift increased, there was an increase in soybean injury and a decrease in shoot dry weight, height, and yield. Simulated mesotrione drift followed by bentazon resulted in synergistic responses in injury shortly after application in some environments. This increase in injury was transient, with no synergistic responses in density, shoot dry weight, and yield. In contrast, antagonistic responses were observed when glyphosate, imazethapyr, or glyphosate plus chlorimuron were applied after simulated mesotrione drift in some environments. Further research is required to develop a better understanding of the interactions of drift followed by the application of an in-crop herbicide.

ABSTRACTThis study aims to determine the vegetative appearance of three genotypes of large-seeded soybean under puddle stress. The Experimental method was used and the plastic buckets as the experimental units were arranged using a Split Plot Design. The main plot was the stress factor (S) consisting of normal conditions (S0) and puddle stress (S1), and the subplot was the genotype factor (G) consisting of G1 (KH1), G2 (Argomulyo), and G2 (Grobogan). Each genotype was repeated four times. The observed variables were plant height, number of leaves, leaf area, number of productive branches, specific leaf weight, root/shoot dry weight ratio. The results showed that there were significantly differences in the appearance of the vegetative characters of the three genotypes of large seeded soybean under puddle stress conditions, especially on plant height, leaf area, plant dry weight, and shoot dry weight. Under puddle stress conditions, KH1 showed the highest of the plant height, root dry weight, and shoot dry weight. Argomulyo showed the highest of the leaf area, while Grobogan did not show as a tolerant variety under puddle stress conditions.

PACOVAN ABSTRACT:In order to achieve high rates of survival during the acclimatization and later planting in the field, was evaluated the in vitro of banana cv. Pacovan plants under different concentrations of sucrose and MS basal salt mixture. The experiment was assembled in a DIC, in 6x2x3, six different culture media [three different MS salt mixture concentrations (100%; 50% of macronutrients; and 50% of macro/micronutrients) and two sucrose concentrations (1.5/3%)], two photoperiods (12/16 hours) and three cultivation times (21, 28 or 35 days). Each treatment was composed by 6 replicates. Plant height, number of leaves/plant, fresh and dry weight of roots and shoots, were analyzed. Satisfactory results for plant height and shoot and root fresh biomass were observed in MS with macro/micronutrients (50%) + sucrose (3%), 16 hours/35 days. The highest values of shoot dry weight were observed in MS with macro/micronutrients (50%) + sucrose (3%); the highest root dry weight was achieved with MS 100% + sucrose (3%) (12hs/28 and 16hs/21 days). The suggested medium for the in vitro elongation and rooting stage of banana cv. Pacovan is the MS with 50% of salts (macro and micronutrients), reduction or maintenance of sucrose (1.5 or 3%) in 16h/35 days of cultivation.Keywords: Musa spp., in vitro propagation, root system. DOI:

Sego SupremeTM is a designated plant breeding and introduction program at the Utah State University Botanical Center and the Center for Water Efficient Landscaping. This plant selection program introduces native and adapted plants to the arid West for aesthetic landscaping and water conservation. The plants are evaluated for characteristics such as color, flowering, ease of propagation, market demand, disease/pest resistance, and drought tolerance. However, salt tolerance has not been considered during the evaluation processes. Four Sego SupremeTM plants [Aquilegia barnebyi (oil shale columbine), Clematis fruticosa (Mongolian gold clematis), Epilobium septentrionale (northern willowherb), and Tetraneuris acaulis var. arizonica (Arizona four-nerve daisy)] were evaluated for salt tolerance in a greenhouse. Uniform plants were irrigated weekly with a nutrient solution at an electrical conductivity (EC) of 1.25 dS·m−1 as control or a saline solution at an EC of 2.5, 5.0, 7.5, or 10.0 dS·m−1 for 8 weeks. After 8 weeks of irrigation, A. barnebyi irrigated with saline solution at an EC of 5.0 dS·m−1 had slight foliar salt damage with an average visual score of 3.7 (0 = dead; 5 = excellent), and more than 50% of the plants were dead when irrigated with saline solutions at an EC of 7.5 and 10.0 dS·m−1. However, C. fruticosa, E. septentrionale, and T. acaulis had no or minimal foliar salt damage with visual scores of 4.2, 4.1, and 4.3, respectively, when irrigated with saline solution at an EC of 10.0 dS·m−1. As the salinity levels of treatment solutions increased, plant height, leaf area, and shoot dry weight of C. fruticosa and T. acaulis decreased linearly; plant height of A. barnebyi and E. septentrionale also declined linearly, but their leaf area and shoot dry weight decreased quadratically. Compared with the control, the shoot dry weights of A. barnebyi, C. fruticosa, E. septentrionale, and T. acaulis decreased by 71.3%, 56.3%, 69.7%, and 48.1%, respectively, when irrigated with saline solution at an EC of 10.0 dS·m−1. Aquilegia barnebyi and C. fruticosa did not bloom during the experiment at all treatments. Elevated salinity reduced the number of flowers in E. septentrionale and T. acaulis. Elevated salinity also reduced the number of shoots in all four species. Among the four species, sodium (Na+) and chloride (Cl–) concentration increased the most in A. barnebyi by 53 and 48 times, respectively, when irrigated with saline solution at an EC of 10.0 dS·m−1. In this study, C. fruticosa and T. acaulis had minimal foliar salt damage and less reduction in shoot dry weight, indicating that they are more tolerant to salinity. Epilobium septentrionale was moderately tolerant to saline solution irrigation with less foliar damage, although it had more reduction in shoot dry weight. On the other hand, A. barnebyi was the least tolerant with severe foliar damage, more reduction in shoot dry weight, and a greater concentration of Na+ and Cl–.
