Abstract:
Plant spacing and weeding are among the key factors determining leafy vegetable growth and yield through maximum utilization of space, nutrients, water and sunlight. Amaranthus species is a popular and very important leafy vegetable crop that is infested and damaged by the arthropod pests in Nigeria. Therefore, this study identified the optimum spacing and proper weeding regime required for the control of leafy caterpillars (Hymenia recurvalis F.) and ensuring the potential yield of amaranths.

Abstract:
In 2016, 10 vegetable amaranth (Amaranthus sp.) varieties were evaluated for fresh greens production in the northeastern temperate climate. Yield, cv, and leaf-to-stem ratios were reported for the eight varieties of edible amaranth (Amaranthus tricolor), one of slender amaranth (Amaranthus viridis), and one of green amaranth (Amaranthus hybridus). All plants were grown using drip irrigation and black plastic mulch under 0.8-mil clear slitted low tunnels. Ten plants of each variety were tested in a randomized complete block design with four replications; the study was repeated seven times over

Abstract:
Amaranth is a promising C4-crop. However, for a wider spread of the crop a better understanding of factors that are influencing yield formation is crucial for optimizing the plant phenotype and enhancing yield. The present study wanted to clarify the effects of assimilate sources and sinks on yield formation by artificially altering source or sink size. Field experiments were conducted in Eastern Austria during three years with three genotypes, applying source-sink manipulation treatments at mid flowering (control, 50% of inflorescence removed, 50% or 100% of leaves removed).

Interference of Powell amaranth (Amaranthus powelliiS. Wats. ♯ AMAPO) in sugarbeet (Beta vulgarisL. ‘Mono Hy A4’) was determined in field experiments. Yield of sugarbeet roots and recoverable sucrose/ha decreased as the density of Powell amaranth increased. At densities of 6, 12, 18, and 24 Powell amaranth plants/30 m of row, root yields were reduced 8, 14, 24, and 25%, respectively, and recoverable sucrose yields were reduced 7, 13, 23, and 24%, respectively.

Field studies were conducted to determine the effect of season-long interference of smooth pigweed or livid amaranth on the shoot dry weight and fruit yield of cucumber. Smooth pigweed or livid amaranth densities as low as 1 to 2 weeds per m2caused a 10% yield reduction in cucumber. The biological threshold of smooth pigweed or livid amaranth with cucumber is between 6 to 8 weeds per m2. Consequently, weed interference resulted in a reduction in cucumber fruit yield. Smooth pigweed, livid amaranth, and cucumber plant dry weight decreased as weed density increased. Evaluation of smooth pigweed,

Having established that the white-seeded amaranth (grain amaranth) can supply both green leaves and seeds (grains) for the Nigerian consumers, there was a need to find cultivars that could yield enough grains to be profitable for an amaranth farmer. Several lines (>100) were screened, with the opaque and creamy-colored seed as the ultimate target. These cultivars, NHAm 261-1 and NHAm258, were selected for yield trials. It was possible to have a high seed rate of 100 plants/m2, and thinning to 22 plants/m2 at the end of 6 weeks. These 22 plants were left to mature, and a maximum of 20 plants

African leafy vegetables have been shown and suggested to have potential to contribute to human diets and alleviate malnutrition; however, their levels of utilisation are currently low especially in South Africa. This is because there is limited access to these crops due to low availability in the market. Limited access is attributed, in part, to the lack of commercialisation as a result of limited agronomic information describing optimum management options for these leafy vegetables. Availability of such information would contribute to successful commercialisation of these crops. The pr
