Background: Borage (Borago officinalis L.) is a valuable medicinal plant with a high content of gamma linolenic acid. It has an important place in Iranian traditional medicine. Although the aerial parts of this plant are extensively used in treatment of diseases, detailed knowledge of the active constituent changes in these parts is not readily available. In addition the most data that has be...

A split plot factorial experiment in RCBD with 3 replications was performed in 2012-2013. Three sesame cultivars namely Biarjomand native, Dashtestan 2, and Darab 1 in the main plot were subjected to drought stress at different growth stages, i.e., control (full irrigation), withdrawing irrigation at 69 BBCH (end of flowering stage) and withdrawing irrigation at 79 BBCH (fully grown fruits). Tw...

ABSTRACT This study was conducted with the objective of evaluating quantum yield, photosynthetic pigments and biomass accumulation mini watermelon cv. Sugar Baby, under strategies irrigation saline water potassium fertilization. The experiment in a randomized block design, 8 × 3 factorial scheme, three replicates, corresponding to eight applied at different phenological stages crop (control - l...

ABSTRACT The objective of this study was to evaluate the effects saline water irrigation management strategies and potassium doses on concentration photosynthetic pigments, gas exchange, fruit production ‘BRS GA1’ yellow passion fruit. experiment carried out under field conditions using a randomized block design, with treatments based 6 × 2 factorial scheme, related six for (irrigation low-sali...

An alternative means by which to examine the importance of assimilates supply to flower and pod formation is to analyze the relationships of leaf area index (LAI), above-ground dry matter (ADM), leaf area duration (LAD) and crop growth rate (CGR) around flowering with flower number and pod/flower ratio. For this objective, an experiment was conducted at Agricultural Research Station of Gonbad, ...

This study investigated the comparative effects of reduced irrigation regimes--partial root-zone drying (PRD) and conventional deficit irrigation (DI)--on the incidence of blossom-end rot (BER) in tomato (Solanum lycopersicum L.) under three Ca-fertilization rates: 0, 100, and 200mg Ca kg(-1) soil (denoted Ca0, Ca1, and Ca2, respectively). The plants were grown in split-root pots in a climate-c...

in order to study the responses of grain yield of chickpea to drought stress and application methods of nitrogen fertilizer, an experiment carried out as split-plot at campus of agriculture and natural resources, razi university, kermanshah, iran, during 2009-10 and 2010-11. the supplementary irrigation at three levels (1. without irrigation, 2. one irrigation at flowering, 3. two irrigations a...
