“…In addition, spraying amino acid (Steam) gave the highest values of plant height, fresh and dry weight of leaves and roots per plant, and diameter of bulb neck [50]. In an experiment developed in a silt loam soil in Thailand, rice husk and rice straw biochar application increased onion yields by 22% and 35%, respectively, compared with the current farmer practice of using raw rice husk [45]. Field experiments in Egypt determined that deficient irrigation negatively altered the yield of stressed onion including bulb length, bulb diameter, bulb weight, and yield; however, soil amendment using biochar and K-humate foliar application boosted the onion yield up to 53.72 t ha −1 [4].…”

“…The dry weight of the plant organs, including pseudo-shoots (DPW), roots (DRW), and bulbs (TBW), was determined by separating the organs, washing them with tap water to remove soil particles, air-drying them for 3 h, and then oven-drying them at 70 °C for 48 h [45]. Harvest index (HI), a measure of the proportion of biomass allocated to the harvested organs (yield, Y) compared to the total biomass (B) produced by the plant, was also calculated.…”

This study examined using peanut shells, rice husks, and cocoa husks as soil conditioners to boost yields in Allium cepa var. Alvara onions. Three types of biochar and four application rates (1%, 1.5%, 3%, and 5%) were compared to a control with no biochar. The biochars had different nutrient makeups, with cocoa husk biochar (CHB) containing the most essential elements. While overall plant growth (height, leaves, and roots) was not significantly affected (p > 0.05) by any biochar type compared to the control, some plant parts responded differently. CHB (5%) and peanut husk biochar (PHB) (1%) yielded the tallest onion plants (71 and 65 cm), while 1% rice and cocoa biochar resulted in the shortest (below 42 cm). PHB (3% and 5%) produced the longest roots (9 cm), while 1.5% rice husk biochar (RHB) had the shortest. Biochar application had no significant effect on leaf count. However, specific application rates of RHB and PHB increased the harvest index (HI), indicating more efficient yield allocation. HI values > 0.85 were obtained with specific biochar rates (e.g., 1.0–1.5% PHB, 1.5–5% RHB, or 5.0% CHB).

“…This was mainly due to improved soil qualities and increased contents of available nutrients. Another study was carried out and results showed that application of rice husk biochar and rice straw biochar increased the yield of spring onion by 22% and 35% as compared to raw rice husk that is a current practice followed by farmers Organic Vegetable Farming; A Valuable Way to Ensure Sustainability and Profitability DOI: http://dx.doi.org/10.5772/intechopen.101095 practice [37]. Nobil, [38] indicated that incorporation of biochar having low density and higher porosity leads to the higher production of basil and lettuce biomass.…”

The most pressing concern in the world since independence has been producing enough food to feed an expanding population. The mix of high-yielding production techniques has helped the globe to generate a food surplus while also raising worries about soil health and environmental pollution. Though, scientists and policy makers are rethinking agricultural systems that rely heavily on biological inputs. Organic farming can provide high-quality food without compromising the health of the land or the environment; nevertheless, it is unclear if large-scale organic farming would be able to feed world’s vast population. Adoption of this emerging approach “organic vegetable farming” plays a vital role in development of agricultural sustainability through avoiding indiscriminate use of synthetic chemicals. There are numerous organic sources for organic vegetable farming but various type of composts (especially vermi-compost) and biochar are most famous among all other organic sources as they improved soil healthy and vegetables productions through improving soil physico-chemical and biological attributes. In addition, demand and prices of organically produced vegetables are much higher in market and evidence showed that organically grown vegetables are enriched with nutrients and safe for consumption because of their less exposure with residues of in-organic pesticides.
