Mechanisms of adjustment by different pearl millet plant types to varying plant population densities

study the effects of intercropping fodder sorghum with pearl millet at different row proportions and plant densities

to study the effects of intercropping fodder sorghum with pearl millet at different row proportions and plant densities, an experiment was conducted at the research farm of university of tehran in 2005. the experimental design was a split plot with three replications. three different densities of 200000, 270000 and 340000 plants per hectare were as main factor and seven different planting propo...

Mechanisms of starvation tolerance in pearl millet.

The response of pearl millet (Pennisetum glaucum [L.]) seedlings to prolonged starvation was investigated at the biochemical and ultrastructural level. After 2 days of darkness the bulk of the seedling carbohydrate reserves were depleted. After 8 days in the dark the respiratory rate had declined to less than 50% of its initial value and the plants had lost half of their total protein content. ...

Aggregate Size Distribution Indices Influenced by Different Types/Managements of Plant Residues under Field Conditions

1- INTRODUCTION Nowadays, environmental aspects of soil erosion are specifically considered by researchers. In this regard, secondary (aggregate) particle size distribution (SPSD) is so important in different issues such as nutrient loss, pollutant transport and carbon cycle. Aggregate size distribution is known as the representative of soil structure, which is by itself regarded as a dynami...

Evaluation of Agronomic Attributes of Canola Cultivars under Different Plant Densities and Application of Humic Acid

To investigate the effect of humic acid application on agronomic characteristics of canola (Brassica napus L.) genotypes in different plant densities, a factorial split-plot experiment was performed using a randomized complete block design with three replications in the Seed and Plant Improvement Institute, Karaj, Iran. Plant density at three levels of 40, 60 and 80 plants/m2 and humic acid at ...
