The appropriate arrangement of sorghum plants combined with the supply nutrients increases grain yield. In this context, objective was to evaluate agronomic performance grown under different plant arrangements and nitrogen fertilization levels. Experiments were carried out in Rio Verde Montividiu a 3 x 2 factorial randomized completely block design six replications, three spacing between rows (...

this study was conducted to investigate the effect of organic and bio-fertilizers on trifluralin durability.herbicide persistence is an important consideration in crop production since residue levels of trifluralin herbicides can persist to the next growing season and may injure sensitive crops in the rotation. residues of trifluralin persist in the soil for long periods. extremely small amount...

The aim of this study is to manipulate musical cues systematically to determine the aspects of music that contribute to emotional expression, and whether these cues operate in additive or interactive fashion, and whether the cue levels can be characterized as linear or non-linear. An optimized factorial design was used with six primary musical cues (mode, tempo, dynamics, articulation, timbre, ...

Twin-row ridge cultivation is widely used in soybean planting northern China. In order to find the optimal parameters of agronomy, twin-row planter with subsoiling was designed. Field experiments were conducted evaluate effects plant arrangements and cluster densities on growth grain yield under different tillage treatments. The experiment a randomised complete block design consisting 20 treatm...

The objectives of this study were to assess the acute-phase protein response of beef steers following vaccination with two different vaccines, and to determine if this response is additive to weaning. Forty-eight Brahman x Angus steers (average age = 7 mo) were randomly assigned to one of six treatments in a 2 x 3 factorial arrangement, including: weaning vs. non-weaning, and vaccination with O...

Two studies were conducted to optimize use of alkaline-treated corn stover and wheat straw and distillers grains as partial corn replacements. In Exp. 1, a finishing experiment used 30 pens (12 steers/pen) of calf-fed steers (initial BW = 374 ± 23.9 kg) with a 2 × 2 + 1 factorial arrangement of treatments with 6 replications per treatment. Factors were grind size, where corn stover was processe...

The nutritional benefits and functional potential of chia seeds have been highlighted in the literature. However, few studies address planting system species, especially its spatial arrangement. Thus, this study proposes to evaluate cultivation under different arrangements, aiming at agronomic performance. experimental design was randomized blocks a 3×2 factorial scheme, with three inter-row sp...

One of the great challenges beet and cowpea cultivation in crop association is to maintain their productivity as that sole counterparts semi-arid environment. In this context, objective work assess whether there bio-agroeconomic return associations beet-cowpea by optimization population densities spatial arrangements component crops. Experiments were performed randomised complete block designs ...
