Pot marigold (Calendula officinalis L.) is a medicinal and ornamental plant. The effect of different concentrations of chlormequat (cycocel), and daminozide, two plant growth retardant, on plant height, flowering, the content of essence and some other traits in pot marigold (Calendula officinalis) was assessed. Plant growth retardants are commonly applied to limit stem elongation and produce a ...

Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...

natural organic wastes contain considerable amounts of nutritional elements. the availability and uptake of nutrient elements in soil) especially in alkali and calcareous soils) increase due to high content of organic matter, and reduce the micro-elements deficiencies. organic wastes have pathogenic contaminations that come from waste type and transmitted by microorganisms such as bacteria, fun...

good perception of relation-sheep among plant morphological traits and resistance to fusarium head blight of wheat is quite effective to make a good success in plant breeding project. in this experiment this relation has been checked out. the morphological traits were included plant height, peduncle length and spike density. we used 28 spring wheat genotypes and 2 durum genotypes. there was sig...

Tillage and crop rotation system effects on corn (Zea mays L.) growth and development have been studied extensively over the past 30 years, but most studies have principally focused on the effects of tillage and crop rotation on mean corn response parameters such as plant height, grain moisture content, and grain yield. As a result, many agronomists and growers have concluded that instances of ...
