BACKGROUND Long-term tillage has been shown to induce water stress episode during crop growth period due to low water retention capacity. It is unclear whether integrated water conservation tillage systems, such asspringdeepinter-row subsoiling with annual or biennial repetitions, can be developed to alleviate this issue while improve crop productivity. METHODS Experimentswere carried out in ...

A study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (Ocimum basilicum L.). The research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. The experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

The cultivation of lemon balm (Melissa officinalis L.) is necessary for pharmaceutical and cosmetic production. aim our work was to investigate the effect plant density as well harvesting method on yield quality characteristics M. officinalis, which used a source polyphenols essential oil in pharmaceutical, food, industries. field experiment carried out two growing seasons (2019 2020). set up 2...

A field experiment was conducted in the Agricultural Research Station, at El-Ghoraieb, Assiut to study dry seed yield performance of two locally adapted cultivars (‘Azmerly’ and ‘Cream 7’) and two line introductions (IT81D-1032 and IT82D-812) of common cowpea (Vigna unguiculata (L.) Walp) grown at three different within-row spaces (20, 30 and 40 cm) and two planting dates in the summer (April 1...

Ultraviolet (UV) disinfection is being increasingly used in drinking water treatment. It is important to understand how its application to different types of water may influence finished water quality, particularly as anthropogenic activity continues to impact the quality of source waters. The objective of this study was to evaluate the effect of inorganic precursors on the formation of regulat...

CMN projected adult size categories: small (<1.5 cm); medium (M1: 1.5-10 cm, M2: >10-20 cm); large (L1: >20-30 cm, L2: >30-40 cm); and giant (G1: >40-60 cm, G2: >60 cm) Total number of naevi in the first year of life: 0, 1 to 20, 21 to 50, 51 or more Additional descriptors of CMN: localization, colour heterogeneity, surface rugosity, hypertrichosis (all none, moderate, marked), presence of nodu...
