to investigate the effect of salicylic acid (sa) on salinity tolerance of two sugar beet cultivars, this experiment was conducted as split factorial based on a randomized complete block design with three replications during growing seasons of 2012 and 2013 in research farm of shahid chamran university. the studied factors were three levels of sa (0 mm, 0.5 mm and 1 mm), two levels of salinity (...

An experiment was carried out to study the performance of different concentrations Amirthakaraisal, a foliar spray, on okra (Abelmoschus esculentus) development and yield. The conducted followed Completely Randomized Design (CRD) with following treatments; T1 - Full recommended fertilizer, T2 Compost 10 ton/ha, T3 5 ton/ha compost as basal topdressing, topdressing 1% (T4), 3% (T5), 5% (T6) Amir...

The application of nutrient solutions to the foliage plants is an alternative means fertilise crops. Foliar fertilisation used overcome disadvantages soil applications. Variable plant responses these foliar spray have often been described in literature. However, knowledge about penetration mechanisms, role a leaf-applied inorganic or organic solution, and results obtained by its still limited. ...

To investigate the effect of salicylic acid (SA) on growth and nitrogen metabolism in mungbean grown under saline conditions, an experiment was conducted in wire house in plastic pots containing soil + sand at NIAB Faisalabd. Mungbean (Vigna radiata L.) varieties, two salt tolerant (NM-98 and NM-92) and two salt sensitive (NM-54 and NM-13-1), identified in laboratory experiments, were grown und...

Yeast associates with many plant parts including the phyllosphere, where it is subject to harsh environmental conditions. Few studies have reported on biological control of foliar pathogens by yeast. Here, we newly isolated leaf-colonizing yeasts from leaves of field-grown pepper plants in a major pepper production area of South Korea. The yeast was isolated using semi-selective medium suppleme...

Striped cucumber beetle, Acalymma vittatum F., is the primary insect pest of cucurbit crops in the northeastern United States. Adult beetles colonize squash crops from field borders, causing feeding damage at the seedling stage and transmitting bacterial wilt Erwinia tracheiphila Hauben et al. 1999. Conventional control methods rely on insecticide applications to the entire field, but surroundi...

In order to study the effect of calcium and humic acid foliar application on growth, yield and yield components of tomato plants as a completely randomized experimental design with four replications. These factors included humic acid in 3 levels (5, 10 and 20 ppm) and calcium in 2 levels (5 and 10 mM) spray on tomato. Results indicated that humic acid (20 ppm) and calcium (10 mM) either alone o...

Three grapefruit orchards on sour orange rootstock were treated by metering DBCP (l,2-dibromo-3-chloropropane) at 56 kg(a.i.)/ha into 15 cm of water in a flood irrigation system. In orchards with 43-49% clay in the surface foot, DBCP reduced numbers of Tylenchulus semipenetrans below control levels for 1.5-2.0 years. In the 3 orchards, DBCP treatment resulted in increases in yield or fruit size...
