“…In another study, conventional furrow irrigation was effective for growth and yield parameters of potato; indicating differences between irrigation methods (Verma et al, 2017). The addition of biochar under deficit irrigation helped to compensate for yield losses of vegetables and further enhanced water use efficiency (Singh et al, 2019). We also found that at least one irrigation could be cut off with the application of biochar.…”

A split-plot experiment was conducted to determine the response of potato to application rate of biochar (0, 2, 4 and 6 t/ha , main plots) and number of irrigations (once, twice and thrice a month, sub-plots) in 3 replications as a pot trial in a screen house at Khumaltar during winter season of 2018 and 2019. Biochar was produced from Lantana camara by semi-pyrolysed technique in a Kon Tiki drum. Plastic pots with 26 cm of diameter were used to meet the 25 cm plant spacing of potato recommended in Nepal. The early maturing (90 days) released variety ‘Desiree’ was used for the trial. Observations were recorded on plant and tuber attributes. The results revealed that the influence of biochar rates was positive over zero biochar on plant height, root fresh weight, root dry weight, stem fresh weight and tuber dry weight. The effect of biochar @ 2/ha had similar effects to the rates of 4 t/ha and 6 t/ha rates. Irrigation treatments were significantly different for plant height, number of tubers per plant, root fresh weight, stem and leaf fresh weight, tuber fresh weight, root dry weight and tuber dry weight. Among the irrigation schedules, irrigating twice and thrice a month had similar effects but they were different from one irrigation. Interactions of biochar @ 2 t/ha with one, two or three irrigations were superior to the interactions of biochar @ 0 t/ha with one and two irrigations for tuber dry weight and total dry weight.

“…However, the majority of these studies investigated cereals crops and effects of biochar on vegetable crops are less reported, e.g., [38,39]. A review by Singh et al [40] reported 10 studies on the effects of biochar on vegetables and found that nine of these studies showed that biochar enhanced vegetable growth, yield and water use efferences. Biochar enhanced tomato growth and soil fertility but did not affect the quality and yield [41].…”

Evaluating the Effects of Biochar with Farmyard Manure under Optimal Mineral Fertilizing on Tomato Growth, Soil Organic C and Biochemical Quality in a Low Fertility Soil

et al. 2021

Biochar amendments are widely recognized to improve crop productivity and soil biogeochemical quality, however, their effects on vegetable crops are less studied. This pot study investigated the effects of cotton stick, corncob and rice straw biochars alone and with farmyard manure (FYM) on tomato growth, soil physico–chemical and biological characteristics, soil organic carbon (SOC) content and amount of soil nutrients under recommended mineral fertilizer conditions in a nutrient-depleted alkaline soil. Biochars were applied at 0, 1.5 and 3% (w/w, basis) rates and FYM was added at 0 and 30 t ha−1 rates. Biochars were developed at 450 °C pyrolysis temperature and varied in total organic C, nitrogen (N), phosphorus (P) and potassium (K) contents. The results showed that biochars, their amounts and FYM significantly improved tomato growth which varied strongly among the biochar types, amounts and FYM. With FYM, the addition of 3% corncob biochar resulted in the highest total chlorophyll contents (9.55 ug g−1), shoot (76.1 cm) and root lengths (44.7 cm), and biomass production. Biochars with and without FYM significantly increased soil pH, electrical conductivity (EC) and cation exchange capacity (CEC). The soil basal respiration increased with biochar for all biochars but not consistently after FYM addition. The water-extractable organic C (WEOC) and soil organic C (SOC) contents increased significantly with biochar amount and FYM, with the highest SOC found in the soil that received 3% corncob biochar with FYM. Microbial biomass C (MBC), N (MBN) and P (MBP) were the highest in corncob biochar treated soils followed by cotton stick and rice straw biochars. The addition of 3% biochars along with FYM also showed significant positive effects on soil mineral N, P and K contents. The addition of 3% corncob biochar with and without FYM always resulted in higher soil N, P and K contents at the 3% rate. The results further revealed that the positive effects of biochars on above-ground plant responses were primarily due to the improvements in below-ground soil properties, nutrients’ availability and SOC; however, these effects varied strongly between biochar types. Our study concludes that various biochars can enhance tomato production, soil biochemical quality and SOC in nutrient poor soil under greenhouse conditions. However, we emphasize that these findings need further investigations using long-term studies before adopting biochar for sustainable vegetable production systems.

“…The results showed that drip irrigation and infiltration irrigation could save more than 50% water, yield improvement and increase water use efficiency by 2-5 times (Hanson and May, 2006;Karlberg and Vries, 2004;Song et al, 2009). New water-saving irrigation technologies, such as drip irrigation and infiltration irrigation, have good water-saving and production increasing effects, but they need to install supporting pressure equipment, water pipeline and emitter, which increased the cost and need high water quality requirements (Li et al, 2019;Mostafa et al, 2018;Singh et al, 2019) and ultimately limit the application of water-saving irrigation technology in agricultural production. The perforated membrane is used to replace the pipes, such as drip irrigation belt and drip irrigation pipe and the perforated membrane is laid in the ridged ditch and then a layer of plastic film is covered on it (Wang et al, 2020b).…”

Water-saving irrigation is an important measure to alleviate the shortage of water resources in China. In this study, the growth, nutrient distribution, quality and yield of Tomato under different irrigation treatments are studied by using microporous membrane water-fertilizer integrated technology and the optimal irrigation water quantity under the condition of microporous membrane water-fertilizer integration was determined. The results show that the stem diameter and the fresh and dry weight of tomato increased under the treatment of microporous membrane irrigation, among which the irrigation of 84 m 3 667 m 2 was the best, comparing with the traditional flooding irrigation. Microporous membrane irrigation promotes the accumulation of N, P and K in tomato plants. The organic acid content of tomato fruit was the highest under the treatment of 108 m 3 667 m 2 and the lycopene content is the highest under the treatment of 96 m 3 667 m 2. However, soluble protein, soluble solids, VC content and sugar acid ratio are the highest under the treatment of 84 m 3 667 m 2 and the yield and water use efficiency of tomato are the highest under this treatment. Generally, the optimal irrigation amount of tomato under the condition of microporous membrane water-fertilizer integration is 84 m 3 667 m 2. The experiment clarifies the crop water demand characteristics and provides a certain theoretical basis for the application of water-saving irrigation technology and high-yield cultivation.
