    tly, the high extraction yield ( mgg-1) of total flavonoids were obtained under the optimal extraction conditions, which are 80°C for 3 h with corn silk over 60% ethanol ratio of Then, the AB-8 resin was selected for the purification of flavonoids due to the higher static adsorption and adsorption capacity than other resins.   In commercial crops, maize (Zea mays) plants are typically grown at a larger distance between rows (70 cm) than within the same row (16–23 cm). This rectangular arrangement creates a heterogeneous environment in which the plants receive higher red light (R) to far-red light (FR) ratios from the interrow spaces.

CropWatch Reader: I presently plant corn and soybeans in inch rows. Corn is no-tilled in bean stubble and beans are planted after one tillage pass in the spring, usually a tandem disc.

I am considering no-tilling soybeans into corn stubble and was wondering what would be the best planting pattern. Summary of Foliar Fungicide Applications on Gray Leaf Spot and Yield of Corn in Iowa in Choosing a Corn Hybrid or Soybean Variety View more ICM News articles about corn.

Grain yield was generally well above to Mg ha -1, the upper grain yield level at which skip-row planting was found to be advantageous compared with planting all rows for grain sorghum. The effect of environmental factors on high corn yields was investigated with field studies using supplemental light, planting patterns, and plant competition.

The supplemental light study was conducted to determine the effect of increasing the light received by the lower two-thirds of the canopy on yield. Surapon Oupadissakoon has written: 'High population planting-patterns for maximum yield in field corn' -- subject(s): Corn, Field experiments Asked in Football.

The objective of this study was to evaluate the effect of population density and row spacing on field yield and other morphological characteristics of two commercial F1 maize hybrids of different biological cycle (Costanza and LG) in a four-year period.

Field experiments were conducted in a split-split plot design, in two population densities and three types of row spacing, involving Author: Vasileios Greveniotis, Stylianos Zotis, Evangelia Sioki, Constantinos Ipsilandis.

Increasing the maize plant population has undergone a constant evolution over the years, with the purpose of enhancing the crop yield. Field trials, in which 2 different experiments were considered, have been conducted in NW Italy in order to analyze the yield benefit of high plant density on recent hybrids, considering both intra-row and inter-row plant by: Crop grown without water stress (five irrigations) resulted in the maximum seed yield of q ha.

while water stress at seed setting gave the lowest seed yield of q hal. In recent years, methods of achieving high maize (Zea mays L.) grain yields have been based mainly on “structurality,” i.e., increasing the maize population and inhibiting individual growth redundancy [].Chen et al.

tand establishment uniformity in corn is an intuitively important component for achieving the maximum yield potential in a given field in a given year.

Uneven stands may be described in terms of plant-to-plant variability for spacing within the row, time of seedling emergence, and/or eventual growth and development. planting pattern by plant population treatment interactions, i.e., corn yield responded similarly to planting pattern across a likely range of plant populations used by growers in each location (Table 3).

At North Platte ingrain yields were greatest in the standard and PISI planting patterns and least in the P2S2. The use of narrow row spacing for the different landscape positions of a field could punish maize (Zea mays L.) grain yield.

Two experiments were conducted (/07 and /08) at different landscape positions in the Inland Pampas of Argentina.

Hybrid DKMG was grown at the commonest plant density used at each landscape position (approximately Cited by: 8. The yield result showed direct proportionality with tomato populations per unit area of land, i.e.

as tomato population increased from 50% to 67% and then to % of component populations, yield. We assessed whether population canopy structure, individual plant photosynthetic characteristics and grain yield were improved due to the optimized ridge and furrow planting pattern, to provide a theoretical basis for the construction of high light use efficiency population and super-high-yield corn cultivation.

Materials and methods Cited by: 7. In whole plot corn yield averages of the three locations were 9, 10, kg/ha. Generally, the higher population treatments had lower yields than the lower populations.

Corn grain yield was also lower in the depressional areas of plot areas due to greater than normal precipitation resulting in water logging. 76 Planting patterns change in the light environment of the soybean canopy through its 77 lower layer (Awal et al., ), especially as the distance between the maize and 78 soybean rows is reduced (Yang et al., ).

Soybean is highly sensitive to low light 79 which results in its low yield (Wolff and Coltman, ). Most studies have mainly 80 analyzed the effects of light.

There was, however, a high correlation (r=) between the percentage N in the leaf ti«ssue and yield of the various irrigation treatments when the treatment was excluded (Figure 29). The percentage of N in corn leaves at near maximum yield is reported to be between and (Pierre et al., ).

According to [] corn and soybean had higher relative yield when grown in intercrop than when grown as a sole crop and the best relative yield total was at the ratio of corn and soybean.

According to [] found that the LER of intercropping was more than one in all nutrient management samples, indicating the yield advantage of maize. Transgenic crops expressing Bt toxins have substantial benefits for growers in terms of reduced synthetic insecticide inputs, area-wide pest management and yield.

This valuable technology depends upon delaying the evolution of resistance. The ‘high dose/refuge strategy’, in which a refuge of non-Bt plants is planted in close proximity to the Bt crop, is the Cited by: Total corn biomass, measured as silage yield, has been shown to be influenced by plant density in New York, USA, where maximum economic forage yield was calculated to occur at plants m-2 (Cox et al., ).Corn (Zea mays L.) and soybean (Glycine max L.
