“…The observed positive effect of BP soil mulching on plant height, leaves area and leaves, shoots and canopy dry weight plant -1 might be due to the enhanced soil temperature, adequate plant microclimates, the absence of light under black plastic mulch, depressed weeds growth and other metabolic activities led to growth characters. Similar kind of observations with respect to plant growth parameters were reported by Coling (1997), Hooks and Johnson (2003), Assi and Rayyan, (2007) and Muhammad et al (2009) and Singh and Ahmed (2008) who proved that, growing potato plants under black plastic mulch caused the highest plant height, leaf area index and main stems number hill -1 .…”

Two field studies were conducted consecutively in the summer season of 2015 and 2016 to investigate the effect of different soil mulching materials (bare soil: BS as a control, white plastic: WP, black plastic: BP and rice straw: RS) on growth, productivity, and water-use efficiency (WUE) of potato under three levels of irrigation (I100=100%, I80=80%, and I60=70% of crop evapotranspiration). Growth characteristics, yield and its components, and WUE were significantly (P ≤ 0.05) affected by both irrigation level and mulching materials. All mulching materials effectively enhanced growth and productivity when compared to bare soil. Potato plants grown under BP and WP as well as RS showed higher mean values of large size (> 60 mm) tubers and WUE compared to non-mulched treatment (BS) in both seasons. Mulching treatments noticeably increased tuber yield in the order of BP > RS > WP. Results displayed that, under different soil mulching materials, the I80 strategy studied here could be successfully applied during summer season in commercial potato production allowing water savings of 20% without any detrimental effect on plant growth or productivity.

“…In addition to consumption, onions are produced for medicinal purposes such as prevention and treatment of blood and heart diseases [5]. The crop is also a rich source of Vitamin C and E [6] and in Uganda, onions contribute to household income especially in highland areas where they are grown purposely for sale [7]. In India, onion is being grown in an area of 0.83 million hectares with production of 13.57 million tonnes and the productivity is 16.30 ton ha -1 which is low.…”

Onion (Allium cepa L.) varieties grown in Uganda are anticipated to have different yield and storage potential. To determine the yield and storage performance of onion varieties, a field experiment was conducted at Namulonge in Uganda. The experiment constituted six onion varieties as treatments arranged in a completely randomized block design (RCBD) replicated thrice. During the cropping seasons, total and economic yield data was collected and analyzed. The total and economic yield of onions were found to be significantly (P= .05) influenced by varietal effects. Among the onion varieties, Bombay red East Africa provided the highest (4690 kg ha-1) yield while the control (local cultivar) yielded (770 kg ha-1) least. The highest economic yield (2867 kg ha-1) was realized from red creole variety while the lowest yield (687 kg ha-1) was obtained from the control. The economic yield of onions was also influenced by cropping seasons with the highest yield (2693 kg ha-1) obtained during 2017B. Although the control yielded least it had the longest shelf life because after 112 days of storage it had the lowest sprouting and rotting percentage (50%). These results are useful in guiding onion farmers in selecting varieties with high yield and storage potential.

Although onion, Allium cepa L., production has been enhanced by the addition of organic matter to soil, other reports indicated no effect. In this study, onion plots (var. Sweet Sunrise) were treated with conventional fertilizer, composted sugar mill ash and vegetative yard waste, or fertilizer + compost. Measurements during two consecutive growing seasons in the Lower Rio Grande Valley of Texas were recorded on soil nutrients, nutrients in onion leaf tissue, leaf lengths, bulb yields in terms of numbers and weights in different size classes, and biochemical qualities. Our study demonstrates that the compost enriched soil fertility, particularly P, K, and Zn; percentage N in the onion leaf tissue was increased to the same extent as plants that received fertilizer; and leaves grew as long as in plots with fertilizer. At harvest, small cull bulbs were consistently the most prevalent in the control, and although compost had a positive influence on numbers and weights of marketable bulbs, fertilizer provided the highest yields during the first growing season. During the second season, however, marketable bulbs in composted plots were as abundant as in the plots receiving fertilizer. Treatment effects on thrips-induced leaf scarring were negligible. We conclude that the compost was useful for increasing marketable onion yield, and that effects improved as the compost decomposed over the two consecutive growing seasons.
