effects of different mulches and saran shading on yield and quality of tomato (lycopersicon esculentum cv. early urbana vf) were studied at ilam university, ilam, iran in 2009. the research work was carried out using a 4×4 split plot experimental arrangment through a completely randomized block design (crbd) of three replications, where shading levels of 0%: no shading; 40%: white; 55%: double-...

ABSTRACT High temperatures may affect the development and yield of sweet potato crop. Technologies such as particle films can mitigate their effects. This study aimed to evaluate effect calcium oxide (CaO) film on remobilization accumulation photoassimilates, well its impact crop yield. The experimental design was randomized blocks, with four replicates per treatment: control, 5, 10 15 % CaO. I...

Abstract Morningglories ( Ipomoea spp.) are among the most troublesome weeds in cucurbits United States; however, little is known about spp. interference with horticultural crops. Two additive design field studies were conducted 2020 at two locations Indiana to investigate of ivyleaf morningglory hederacea Jacq.), entireleaf Jacq. var. integriuscula A. Gray.), and pitted lacunosa L.) triploid w...

using mulch to decrease and optimize water use is known as a practical method. for this purpose, a split-factorial experiment based on complete block design with three replications on two melon cultivars was conducted in spring season of 2010 in torbat-e-jam. interval irrigation treatments in three levels (6, 8 and 10 days) were considered as main plot and mulch (straw plus paddy rice, plastic ...

Thirty-nine commercial varieties of head cabbage were evaluated for feeding preference of the diamondback moth (DBM), Plutella xylostella, at Kula, Hawaii, USA. Varieties were evaluated for density of caterpillars, extent of feeding damage and percentage of marketable heads. Twelve out of 39 (31%) varieties that showed the least DBM caterpillar damage and produced high percentage of marketable ...

The yield and fruit quality of processing tomatoes (Solanum lycopersicum L.) have increased markedly over the past decades. aim this work was to assess effects organic (OFS) conventional farming systems (CFS) on main agronomic parameters involved in tomato components traits heirloom modern genotypes. Marketable from genotypes, both OFS CFS, showing a difference ?20 t per hectare favor CFS. Tota...

Plant tolerance to salinity stress is vital for irrigation scheduling, decision-making, planning and operation, water resource management. This study aimed investigate the effects of on use, growth, physiology, yield parameters drip-irrigated tomatoes in two different growing seasons. In addition control (0.7 dS m−1), three levels: 2.5 (low), 5.0 (moderate), 7.5 (high) m−1 were used. both seaso...
