Erodibility of the soil is the sensitivity of the soil to erosion, the higher erodibility value of the soil the easier the soil erodes. One way to reduce the rate of erosion is by covering the soil with mulch. The purpose of this study is (1) to know the effect of plastic mulch and straw on the cultivation of tomato plants on the level of soil erodibility and (2) to know the type of mulch which gives the lowest soil erodibility level in tomato cultivation. The design in this study uses a Completely Randomized Design with treatment consisting of tomato plants planted without mulch, tomato plants planted using black plastic mulch, tomato plants planted using silver plastic mulch, tomato plants planted using transparent and tomato plants planted using straw. The results showed that the treatment without mulch and treatment with straw had increased erodibility values, while the treatment using black plastic and using silver plastic had decreased erodibility value. In the treatment with transparent mulch there is no effect in erodibility value. Each treatment had different values but had the same level of category, which is very high. The type of mulch who had the lowest value is the treatment silver plastic mulch with an erodibilitas value of 0,58 at the beginning of cultivation and 0,55 at three months of planting age.   Keywords: Soil erodibility, tomato plants, mulch.

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.

North Carolina is experiencing a revitalization of the strawberry industry due to the adoption of plasticulture technologies and the California cultivar Chandler, which produces excellent yields and fruit quality on black plastic mulch. With this system, berries can be harvested in just 7 to 8 months after planting. The spring harvest season can last up to 6 weeks in most years. Strawberry plasticulture growers in North Carolina typically experience yields of 17,000 to 18,000 lb/acre (19,054 to 20,174 kg·ha-1). Cash expenses for the system are about $4345/acre ($10,736/ha). The system requires both an overhead sprinkler system for blossom and bud frost/freeze protection, and drip irrigation for supplying water and fertilizer in the prebloom, bloom, and fruiting periods. Sandy loam and clay loam soils are ideal for forming the lo-inch-high (25.4-cm) beds with bedding machines. Usually, 33% of the N, 50% of the K, and all of the P is applied preplant, with the remaining N and K applied through the drip-irrigation system. Problems associated with the plasticulture system include higher initial investment relative to matted-row production, and only one fruiting season is possible with the anthracnose-susceptible `Chandler' in the southeastern United States.

AbstractStrawberry (Fragaria x ananassa Duchense ex Rozier) is an important horticultural crop grown in Latvia. The aim of this research was to evaluate some newly introduced strawberry cultivars and perspective hybrids and to evaluate the efficiency of natural calcite leaf fertiliser (Megagreen®) on strawberry fruit quality and spread of pests and diseases. The trial was established in 2012 at Pûre, Tukums Municipality. Cultivars ‘Saint Pierre’, ‘Annapolis’, ’Sonata’, ‘Chambly’, ‘Elegance’, ‘Rumba’, ‘Honeoye’, ‘Senga Sengana’ and two hybrids: 35-1 and 39-1 were included in the investigation. Calcite fertiliser was applied four times per season in 2013 and 2014 by spraying on leaves in concentration 0.5%. Strawberries were grown on two row beds with black plastic mulch and drip irrigation. The evaluation was done for two seasons. Most of the evaluated newly introduced cultivars and hybrids had better fruit quality and resistance to diseases than control cultivars. Cultivars ‘Annapolis’, ’Rumba’, ‘Sonata’, ‘Elegance’, and 39-1 were selected as the most promising related to fruit quality and resistance. The application of calcite fertiliser (Megagreen®) on leaves had no statistically significant effect on strawberry fruit quality and resistance.

Paper mulch and black plastic mulch were compared with no mulch on tomatoes (Lycopersicon esculentum Mill. `Better Boy' and `San Marzano') for incidence of blossom-end rot (BER) in the field during 1988–90. Early season (late July to late August) harvest had more BER than in later pickings. Black plastic mulch significantly increased early season BER in `Better Boy' relative to paper or no mulch. Late-season BER in `San Marzano' was decreased with paper or black plastic mulch relative to no mulch.
