“…found that the incorporation of green manure had positive effects on soil physical, chemical, and biological properties, plant nutrition, and crop yield. Some results also indicated that green manuring increased plant leaf and root dry weight, grain yield, and crop N and P uptake (Astier et al, 2006;Bilalis et al,2009;Blaise, 2011;Rahman et al, 2011). The present results showed that application of ryegrass green manure significantly increased the upland rice dry weight and grain yield in the first growth season by an average of 62.9% and 55.1%, respectively.…”

A 9-year field micro-plot experiment was conducted to investigate the use efficiency, residual effect, and fate of 15 N-labelled ryegrass green manure in soil-crop system, so as to offer useful information for reasonable application of green manures on meadow burozem. Results showed that high application rate (600g per plot) of 15 N-labelled ryegrass green manure resulted in reduction of percent recovery (PR) 15 N plant and PR 15N soil by 25.0% and 12.8%, respectively, and elevation of percent loss (PL) 15 N by 31.2%, as compared with low application rate. The 15 N utilization and loss could be divided into three phases, i.e., high uptake and fast loss in the first and second growth seasons, low uptake and slow loss in the following four growth seasons, and little change in the last three growth seasons. This suggested that the green manure N had a long residual effect but its loss was faster at early phase, and thus, rational application of green manure was of considerable importance to reduce its N loss while improve its N use efficiency.

“…This suggests that the planting and management techniques used for these living mulch treatments were successful in preventing competition with the cotton crop. Reduced tillage and use of a short duration sunnhemp intercrop has been previously reported to improve cotton yields in the Vidarbha region [6]. However, in the Blaise [6] study, sunnhemp was planted late and incorporated into the soil relatively early.…”

“…A group of studies conducted in the Vidarbha region [6] reported that a short-duration sunnhemp intercrop, in combination with reduced tillage practices did not contribute to weed suppression. However, few studies have examined the management and impact of long duration living mulch stands in long duration crops such as cotton under tropical climates.…”

Living Mulch Performance in a Tropical Cotton System and Impact on Yield and Weed Control

Cotton (Gossypium hirsutum L.) is a major crop in the Vidarbha region of central India. The vertisol soils on which much of the cotton is grown have been severely degraded by the tropical climate, excessive tillage and depletion of organic matter. Living mulches have the ability to mitigate these problems but they can cause crop losses through direct competition with the cotton crop and unreliable weed control. Living mulch height was controlled through mowing and herbicides were not used. Living mulches generated 1 to 13 tons ha −1 of dry matter across sites and years. Weed cover was negatively correlated with both living mulch biomass and cover. Where living mulches were vigorous and established quickly, weed cover was as low as 7%, without the use of herbicides, or inter-row tillage. In a dry year, living mulch growth had a negative impact on cotton yield; however, in a year when soil moisture was not limiting, there was a positive relationship between cotton yield and living mulch biomass. Use of living mulches in cotton production in the Vidarbha region of India is feasible and can lead to both effective weed suppression and acceptable cotton yields.

“…This is because both excreting growth inhibiting substances and N starvation during decomposition of green manures often have a suppressive effect on early growth of the succeeding crop (Daimon and Kotoura, 2000;Uratani et al, 2004;Daimon, 2006). In general, a month after incorporation is needed for maturation of green manures (Ngouajio and Mennan, 2005;Liebman and Sundberg, 2006;Blaise, 2011;Espinoza et al, 2012). Although seed rhizomes of turmeric were planted 11 days after incorporation of faba bean residues in the present experiment, no inhibition of turmeric emergence was observed in any plot, and plantlet emergence rate was 100% at 30 DAP (41 days after incorporation of the faba bean residues).…”
