“…Cover crops mulches or recently terminated cover crops may also reduce soil temperature and thus soil drying, particularly in no-till production systems [143]. Delayed soil warming in the spring may delay tillage, planting and emergence and thus reduce yields [144].…”

Abstract:In light of the environmental challenges ahead, resilience of the most abundant field crop production systems must be improved to guarantee yield stability with more efficient use of nitrogen inputs, soil and water resources. Along with genetic and agronomic innovations, diversification of northern agro-ecosystems using inter-seeded legumes provides further opportunities to improve land management practices that sustain crop yields and their resilience to biotic and abiotic stresses. Benefits of legume cover crops have been known for decades and red clover (Trifolium pratense) is one of the most common and beneficial when frost-seeded under winter wheat in advance of maize in a rotation. However, its use has been declining mostly due to the use of synthetic fertilizers and herbicides, concerns over competition with the main crop and the inability to fully capture red clover benefits due to difficulties in the persistence of uniform stands. In this manuscript, we first review the environmental, agronomic, rotational and economical benefits associated with inter-seeded red clover. Red clover adaptation to a wide array of common wheat-based rotations, its potential to mitigate the effects of land degradation in a changing climate and its integration into sustainable food production systems are discussed. We then identify areas of research with significant potential to impact cropping system profitability and sustainability.

“…In okra with relatively large seeds, Odeleye et al reported that planting beyond 3cm depth led to reduced emergence, vigour and yield. Effects of sowing depths have also been reported in pigeon pea (Tayo, 1983); Corn (Gupta et al 1983, Alessi andPower (1971), Soybean, Abrecht 1989, but the seeds of all these crops are much bigger than those of Amaranthus and Celosia . Farmers usually mix the seeds of these crops with soil and broadcast.…”

Screen house trials were carried out to evaluate the optimum sowing depths of Amaranthus and Celosia at the National Horticultural Research Institute, Ibadan, Nigeria. Seeds of NHAc3 and ED82/1040A varieties of Amaranthus and local green and TLV8 of Celosia (chosen on the basis of maturity period) were sown at 0,1,2 and 3cm depths using split-split design in randomized blocks with 4 replications. Data were taken on % germination, seedling emergence and establishment indices. Results indicate that Celosia had a higher % seedling emergence than Amaranthus . However, Amaranthus grew significantly taller than Celosia at plant establishment. Highest number of seedlings emerged at 0 cm depth but plants had highest number of leaves and total fresh vegetable production at 1 cm sowing depth. The two crops sown at and 1 cm gave significantly higher root development index than other interactive effects. However, the highest shoot development index was obtained at 0cm depth. The study demonstrated a significant interaction of sowing depth x variety such that the varieties (irrespective of species) performed best at 1 cm depth. The early maturing variety in the crops also had higher vigour, germination and root and shoot development indices than the late maturing variety.

“…According to Alessi and Power (1971) a 10 mm increase in planting depth at a constant temperature of 13 o C results in a delay in emergence by 1 day. Gupta et al (1988) deduced that with an increase in planting depth from 25 mm to 75 mm, time to corn emergence increased, due to a decline in temperature with depth and the increase in distance the cotyledon has to travel before emergence.…”

Average maize grain yields in developing countries are 1.8 Mg ha -1 compared to 9.9 Mg ha -1 in the USA, with much of this due to planter technology. Thirty million hectares in the world are planted by hand, where 2 to 3 seeds are placed per hill at uneven spacing resulting in heterogeneous plant stands. A hand planter was built to deliver single seeds with each strike (singulation) and to improve low grain yields encountered in developing countries. This study was conducted to evaluate drum cavity size and planter tip on singulation and plant emergence in maize, using the OSU hand planter. Two drum cavity sizes, two planter tips and four different seed sizes were used in a two-year study, started in 2014. On all four site years drum cavity 450S resulted in significantly similar emergence as those checks planted by hand and a John Deere vacuum planter. Over site years 17% better emergence was achieved with 450S vs 260-20 drums. Drum 260-20 was better at delivering singulation than 450S however, over four site years 27% misses (no seed delivered) were recorded with drum 260-20. No significant difference was seen with different tips on emergence, singulation and final grain yield. This data suggests that maize producers in developing world could use the OSU hand planter with drum 450S and the conventional tip. This planter can be used as a side-dress N-fertilizer applicator by simply changing the internal drum, that incorporates urea into the soil, minimizing volatilization losses. It also removes chemically treated seed from producer hands thus reducing health risks.iv
