“…In the same context, results presented by Nicou et al showed significant positive effect of soil tillage on yields of various crops in the West African semi‐arid tropics. In fact, soil tillage may improve soil properties (water content, aeration, infiltration and thermal conditions) and the uptake of some mineral elements . In our experiment, soil tillage was conducted four times per season (in February, June, August and mid‐October) which contributed to the increase of soil's ability to hold the high precipitation that occurred in March (43 mm and 66 mm, respectively, in the 2013 and 2014 seasons) and also the autumn and winter rainfall that occurred from September to December (reaching 55 mm and 80 mm, respectively, in September and December 2013) (Fig.…”

“…Although NT is recognized as one of the Conservation Agriculture practices (Lal, 2004;Reicosky and Saxton, 2007;Martínez et al, 2008;Tabaglio et al, 2009;Kolb et al, 2012;Soane et al, 2012;Fiorini et al, 2018), its adoption requires a transition phase (on average 7-8 years), characterized by higher annual weed and disease pressures, slow rebuilding aggregates in soil, and lower and variable yields (Knowler and Bradshaw, 2007;Pagnani et al, 2019). However, as outlined in Sharma and Abrol (2005), soil types react differently to the same tillage method. That certainly why the grain yield had significantly decreased by 708.8 kg.ha -1 under no-tillage at Za-zounmè, whilst it increased by 262.8 kg.ha -1 at Dan under no-tillage between 2018 and 2019.…”

“…NT practices are considered as Conservation Agriculture practices (FAO, 2011) and reaching up to 70% of the total cultivated area in South America. However, various soil types react differently to the same tillage method with respect to some selected soil properties, and the effects of tillage method on crop Akplo et al 9 yield vary with the crop species (Sharma and Abrol, 2005). In Africa and Europe, NT practices are not widespread and a decrease in crop yield and an increase in runoff and soil loss during its establishment has been reported (Akplo et al, 2019a;Basch et al, 2008;Pittelkow et al, 2015).…”

Soil quality constitutes a major factor for crops growth. This study aimed at determining the sustainable soil conservation practices that would increase maize growth as well as production and improve the soil moisture. Two experimental sites were chosen: Dan localized on Acrisol and Zazounmè localized on ferralsol. Two cropping seasons were investigated: the long rain seasons of 2018 and 2019. The experimental design was split-plot with four replications. The main factor was tillage with three modalities: no-tillage (NT); ridging parallel to the slope (PR); Isohypse ridging (IR) and the second factor was mulching with four amounts: 0, 3, 5 and 7 t.ha -1 . Tillage, mulch amount and their interaction significantly influenced the soil moisture, maize growth and yield over the two investigated cropping seasons at both sites whereby the highest values were obtained under IR for tillage, 7 t.ha -1 (for mulch amount) and IR7M (for the interaction tillage x mulch amount). Overall, IR significantly increased the maize growth speed by 8% at Dan and by 16% at Za-zounmè; the maize grain yield by 33% at Dan and by 30% at Za-zounmè and the soil water content by 24% at Dan and 20% at Za-zounmè, in comparison with No-Tillage. An increasing effect of mulch amount was also observed. As far as mulching is concerned, the highest values (in average of LR2018 and LR2019) of growth speed (3.77 cm.day -1 at Dan and 4.08 cm.day -1 at Za-zounmè); grain yield (3003.03 at Dan and 3471.09 kg.ha -1 at Za-zounmè) and soil water content (26.89 mm at Dan and 20.44 mm at Za-zounmè) were observed. This suggests that isohypse ridging associated with an appropriate amount of organic mulch could be an option to mitigate dry spells and drought and improve local farmers' income in the area of low rainfall in sub-Sahara Africa.

“…Sivakumar et al [12] observed that two irrigations increased sorghum yields from 2430 -5990 kg•ha −1 . Single 50 mm irrigation from runoff harvesting in the watershed increased sorghum yields from 2570-3570 kg•ha −1 [13] [14].…”

Sorghum (Sorghum bicolor L. Moench) is cultivated as monocrop in Eritrea. Efforts were made to grow sorghum-pigeonpea (Cajanus cajan L. Millspp.) intercrop on the tillage, fertilizers and supplementary irrigations necessary for sorghum. Experiments were conducted in terraced fields at Hamelmalo during 2013-15 to evaluate growth and yield of sorghum-pigeonpea intercrop in split plot design with conventional tillage (CT), reduced tillage (RT) and zero tillage (ZT) in main plots and rainfed (I 0), 50% of full irrigation (I 1), 75% of full irrigation (I 2) and 100% of full irrigation (I 3) in subplots. All irrigations were stopped 15 days before sorghum maturity. Full irrigation was 60 mm applied at 50% depletion of available soil water in 1 m profile. Sorghum growth was faster than pigeonpea until 85 days from planting and pigeonpea growth accelerated only after sorghum harvesting. About 80% of sorghum roots were within 0.6 m profile but more than 75% of pigeonpea roots were below 0.60 m depth. This showed a weaker competition between the two crops for nutrients, water and light. Both grain and stover yields of sorghum were optimum in RT + I2 during the 2 years. Highest grain yield was 6900 kg•ha −1 in RT + I 3 in 2013, which was at par with that in RT + I 2. Mean residual soil moisture at sorghum harvesting was 74 mm•m −1 , which decreased to 8 mm•m −1 by pigeonpea harvesting. Residual moisture was more in the irrigated than non-irrigated plots. Pigeonpea yields were optimum (1363 kg•ha −1) in RT + I 3 and lowest (297 kg•ha −1) in ZT + I 0. Average water use by sorghum-pigeonpea was 374 mm by sorghum harvesting and 438 mm by pigeonpea harvesting, producing total sorghum equivalent yield of 7475 kg•ha −1. This raised average water use efficiency from 12.6 kg•ha −1 •mm −1 at sorghum harvesting to 17.1 kg•ha −1 •mm −1 at pigeonpea harvesting. Benefit was doubled at 50% of full irrigation and >4 times at 75% of full irrigation.
