Bedded sweetpotatoes are often covered with a rowcover to enhance sprouting. Our study was conducted to evaluate several rowcovers for earliness, plant yield, and plant quality (weight). In 1993 and 1994, variety (`Beauregard' and `Jewel') and rowcovers (clear plastic; black plastic; photodegradable plastic; infrared transmissible plastic; Reemay polyester cover; and black plastic, which was then covered with a black plastic tunnel) were evaluated for their effects on plant production. Holes ≈1 cm in diameter were punched in the plastic ≈2 weeks after planting to prevent exposing the seed roots to excessively high temperatures. Rowcovers were removed when plants began emerging from the soil, except for Reemay and the black plastic tunnels, which remained in place over the bedded plants until first plant harvest. Black plastic tunnels were placed back over the treatment bed each time plants were harvested. When 50% of the plants were 25 cm tall, all plants from the plot were cut 1 to 2 cm above the soil line. Plots were arranged in a randomized complete-block design and replicated five times. `Jewel' produced plants earlier than `Beauregard'. Covering beds with black plastic mulch and tunnels resulted in the first plant cutting being up to 42 days earlier than the other treatments, with no rowcover treatments producing plants the latest. The second earliest cutting was obtained when beds were covered with Reemay rowcover. Plant fresh weight was greater with the no cover treatments; black plastic tunnel treatments produced the lowest weight plants. Using black plastic tunnels consistently produced more plants than the other treatments. In the future, using rowcovers to enhance slower sprouting varieties should be examined.

ABSTRACT In Brazil, studies on commercial exploitation of yacon are still scarce. A growing interest in this vegetable has demanded some researches on this crop cultivation management, though. Considering that yacon has a long cycle, which exposes the soil, studies on mulch management will be of great value. We used a randomized complete block design, with five replicates, under different soil mulches for yacon cultivation: two plastic film covers (black and double-sided), four mulches (corn husk, coffee husk in three levels), and the control (bare soil). Plastic mulch can be used for yacon cultivation, considering that the double sided plastic provides greater production of total roots; however, the same yield of the most valued roots was obtained using black plastic. The second highest total productivity and the highest commercial yield in the most valued root classes were obtained using 50 L m-² of coffee husk as mulch, representing a good alternative for farmers.

The effects of two mycorrhizal species (Glomus versiforme and Glomus intraradix) and a control on the growth of green pepper, Capsicum annuum, and lettuce, Lactuca sativa, seedlings have been evaluated using four types of growing media (Peatwool, Fafard bulk mix. Cornell mix and a compost based mix) and two types of containers, Cell Packs (125 cc volume) and Pro-Trays (65 cc volume) for green pepper and Cell Packs (125 cc volume) and Plug Flats (33 cc volume) for lettuce. The experiments were split plot randomized Complete block design with 6 blocks (lettuce) and 4 blocks (pepper). Seeds were sown directly into the containers of mycorrhizal inoculated media. All treatments received the same fertilizer regime. Cell volume had no significant effects on green pepper fresh weight, dry weight, stem diameter, leaf area or leaf number but the lettuce Cell Pack plants had significantly higher fresh and dry weights, more leaves and higher leaf area. The Fafard Bulk and the Compost mix gave significantly higher fresh and dry weights than did the other two media for both green pepper and lettuce. Mycorrhizal species did not influence plant growth with the exception of leaf area in green peppers and shoot dry weight in lettuce.

<em>The estimated value of genotype variability, phenotype variability, environmental variability, and heritability have an important role in breeding activities of tea</em> <em>in order to create the superior varieties. The objective of this study was to investigate the phenotypic performance, genotype and phenotype variation, and heritability value of nine genotypes of tea. The study was conducted at Pemandangan block, Tambi Plantation Unit,  Wonosobo, Central Java, from April 2013 until April 2014. The Randomized Complete Block Design (RBD) with nine treatments and three replications was used in this study. The 9<sup>th</sup> of treatments consisted of 2 genotypes of tea resulting from a cross (GMB 3 and GMB 4), 2 introduced genotypes (TRI 2024 and TRI 2025), and 5 local genotypes resulting from selection (Cin 143, Kiara 8, RB 3, Tambi 1, and Tambi 2). The results showed that the genotype of GMB 3 more higher than other genotypes in pecco length, leaf length, leaf width, length of leaf stalk, and length of leaf internodes characters, whereas Tambi 2, GMB 3, and GMB 4 more higher in fresh weight of P+2 and P+3. The production of fresh shoot of GMB 4 more higher than the other genotypes, but not significant with GMB 3 and RB 3. The leaf length and fresh shoot production characters has a wide of genotype and phenotype variability, whereas the high of heritability value were found in all characters observed. The selection based on leaf length and fresh shoot production characters will be effective because both characters have a high genotypes variability and heritability.</em>

Sweet pepper is attacked by a number of viruses which cause serious yield losses for many growers. The influence of mulching on virus disease incidence in sweet pepper was studied under irrigation in NIHORT. Healthy seedlings were transplanted to the field and arranged in a randomized complete block design (RCBD). Different mulch used included air-dried leaves of Azadirachta indica (Neem), Tithonia diversifolia (Tithonia), Neem + Tithonia (w/w) and plastic mulch (white, black and yellow) while the control had no mulch. Incidence and severity of virus-like diseases on growth and yield were evaluated. Result indicated that plants grown using white plastic mulch had the lowest disease incidence of 34.43%. Plants grown with Tithonia, Neem, and Neem + Tithonia mulch had high disease incidence of 100%, 88%, and 90.60% respectively. Average virus disease severity ranged from 2.30 and 3.33 on a scale of 1-5 scoring system. Symptoms observed on symptomatic plants include mosaic, mottle, wrinkle and leaf reduction. Plots treated with black plastic mulch produced the lowest fruit weight, while the white and yellow plastic mulch induced highest fruit weight found. The results obtained showed that white and yellow plastic mulches are effective management options for viruses of sweet pepper.

The types of plastic mulch used in horticultural production often fulfill only a few of the grower's needs. Black plastic mulch controls weeds, but can burn young plants. Clear mulch, while warming the soil and enhancing early crop growth, allows prolific weed growth and development. Accordingly, an experiment using a randomized complete-block design with-four replications was set up to compare the effects of black, microperforated black, silver, and wavelength-selective (IRT-76) green mulches, and bare soil on weed growth and development, and on soil temperature and moisture. Each mulch was evaluated for its optical properties. All mulches significantly reduced final stands of seeded weeds compared with bare soil. IRT-76 green had the warmest mean soil temperatures, followed by silver, black, and microperforated black mulches, and bare soil. Soil moisture content was generally higher under plastic mulches than bare soil.

A study was conducted to assess the effect of drip irrigation and plastic mulch on growth and seed yield of Semialata. Two types of plastic mulch (green and silver/black) were tested at three levels of irrigation (120%, 100% and 80%) by drip irrigation and one level (100%) by furrow irrigation. The daily water requirement of Semialata was estimated by the equation ETcrop= ETox crop factor. ETcrop is crop water requirement mm/day. ETo (reference evapotranspiration, mm/day) was calculated by FAO calculator which uses temperature and humidity data. In this experiments there were twelve treatments were considered. The treatments were replicated thrice. The experiment was laid in randomized block design. It was observed that drip irrigation with or without plastic mulch is yielding better results in terms of growth parameters and seed yield as compared to furrow irrigation without plastic mulch. It was also observed that maximum suppression (67.58%) of weeds resulted with drip irrigation and silver/black plastic mulch at 80% level of irrigation.

To study the effects of cover methods and nitrogen (N) levels on the growth and yield components of tomato Cv. Pear F1, field experiments with a 4x3 factorial design were conducted in the 2019 spring and winter seasons using a randomized complete block design with three replications. The cover methods included four treatments: bare soil (BS), black plastic mulch (BPM), transparent polypropylene row cover (RC), and a combination of BPM and RC (BPMRC) with the RC removed approximately 30 days after transplanting. Nitrogen (N) was applied at three levels (150, 180, and 210 kg N ha-1). Using BPM and RC generally led to an increased air temperature, air humidity, soil moisture, and soil temperature compared to the BS treatment. Higher N rates (180 and 210 kg N ha-1) did not result  in different tomato fruit sizes and fruit weights but positively increased fruit yield and quality (Brix values and fruit dry weight) as compared to the 150 kg N ha-1 addition. The cover methods positively affected the yield components and fruit yield of tomato as well as the fruit characteristics compared to the BS treatment. Using cover materials (BPM and RC) combined with a higher N application significantly increased the yield attributes and fruit yield. The highest fruit yield was achieved under the mulching treatment by black plastic (BPM treatment) combined with a 210 kg N ha-1 application, resulting in 50.90 tons ha-1 in the spring and 58.27 tons ha-1 in the winter.
