BACKGROUND: Organic farming has emerged as important priority area globally in view of growing demand for safe and healthy food and long term sustainability and concerns on environmental pollution associated with indiscriminate use of agrochemicals. Nano fertilizers can be easily absorbed by crops and may exhibit a prolonged effective duration of nutrient supply in soil/crop co...

Harvest index is a measure of success in partitioning assimilated photosynthate. An improvement of harvest index means an increase in the economic portion of the plant. Our objective was to identify genetic markers associated with harvest index traits using 203 O. sativa accessions. The phenotyping for 14 traits was conducted in both temperate (Arkansas) and subtropical (Texas) climates and the...

BACKGROUND: Polyacrylamide is the main synthetic polymer used, and it absorbs water through the formation of hydrogen bonds. Super Absorbent Polymer (SAP) can absorb water up to 200-400 times its weight and increase its size by up to 100 times. OBJECTIVES: Evaluate effect of different irrigation regime and super absorbent polymer on agrop...

Leaf developmental traits are an important component of crop breeding in small-grain cereals. Surprisingly, little is known about the genetic basis for the differences in barley (Hordeum vulgare L.) leaf development. The two barley row-type classes, i.e., twoand six-rowed, show clear-cut differences in leaf development. To quantify these differences and to measure the genetic component of the p...

in order to study the effect of nitrogen level on physiological characteristics, grain yield and yield components of tetraploid wheat genotypes, a split plot randomized complete block design field experiment with three replications was conducted in 2007 at research farm of isfahan university of technology. four levels of nitrogen fertilizer (20, 80, 140 and 200 kg/ha) were chosen as main plots ...

Genetic progress for forage quality has been poor in alfalfa (Medicago sativa L.), the most-grown forage legume worldwide. This study aimed at exploring opportunities for marker-assisted selection (MAS) and genomic selection of forage quality traits based on breeding values of parent plants. Some 154 genotypes from a broadly-based reference population were genotyped by genotyping-by-sequencing ...

currently deficiency of raw materials and initiative resources caused an increasing need of cellulose industries to new lingo cellulose products and resources. kenaf as a fibrous plant is considered along with the other plant sources that their bast has suitable fiber. this experiment was carried out in split–plot form with 4 replication in order to evaluation effect of harvest time and genotyp...
