“…Intercropping is the growing of two or more crops on the same piece of land within the same year (Sullivan, 2003). Intercropping is advocated due to its benefits for yield increase on a given piece of land by making use of resources that would otherwise not be utilized by a single crop (Gana and Busari, 2003). One of the goals of intercropping is to control weed (Poggio, 2005) and control legume root parasite infections (Fernandez-Aparicio et al, 2007).…”

Though Nigeria is blessed with vast land and human resources suitable to produce enough food for her teeming population, low productivity in crop production has constrained her food sufficiency effort; this however calls for crop production mixture expansion strategies. The study evaluates the economics of yam-cowpea intercropping in Obi Local Government of Nasarawa State, Nigeria. The specific objectives were to describe the Socio-economic characteristics of yam-cowpea intercrops farmers; identify the sources of fund; to estimate input-output relationship in yam-cowpea production in the study area; determine the cost and returns on yam-cowpea production; and identify the major constraints to yam-cowpea inter-cropping system. A multi-stage sampling technique was used to select 80 yamcowpea intercrops farmers, farm input-output data were collected based on 2015 cropping season with the aid of a structured and validated questionnaire. The results revealed that 83.8% of the respondents were males; most of the farmers (76.4%) had formal education and majority of the respondents (77.6%) had farm size of 0.5 to 2 ha. The results further revealed that majority of the farmers (57.5%) got their finances from their personal savings. The double-log production function analysis reveals that the coefficient of multiple determination, (R 2 = 0.908) indicated that 91% of the variation in the value of the output (₦/ha) was explained by independent variables. Yam sett and labour were found to be significant at 1% while agrochemical was found to be significant at 5% in increasing the value of the output. The gross margin analysis showed that Gross Margin (GM) was N25, 455.30 with return per naira invested of 0.11. The study also revealed that high cost of inputs, pests and diseases and inadequate capital were the major constraints to yam-cowpea production in the study area. The study recommended that inputs (yam setts and agrochemicals) supply at subsidized rate to farmers in the area should be enhanced. There is need to make funds accessible and available for the farmers in the study area through the creation of functional rural micro finance institutions.

“…DASS: days of the intercropped planting after sugarcane sowing; DASH: days of the intercropped planting after sugarcane harvest; 0: legumes were planted same day with sugarcane. In several studies, sugarcane intercropped with legumes or food crops had low yields and unfavourable sugarcane economies (Parsons and Be, 2003, Gana and Busari, 2003, Roodagi et al, 2001a, Billore et al, 2000, Parsons and Khubone, 1999. However, advantages of legumes in intercropping include soil improvement, which addresses the need for sustainable agriculture to increase farm profits (Islam et al, 2009, Malavia et al, 1992, Goviden, 1991, Souza Filho and Andrade, 1985.…”

“…The potential of legume intercropping to mitigate N2O production has been studied in herbaceous perennial pasture grass and grain cropping systems (Huang et al, 2014, Dyer et al, 2012, Hauggaard-Nielsen et al, 2016. Most research on sugarcane-legume intercropping systems has focussed on evaluating profitability and the effects on soil improvement (Córdova-Gamas et al, 2016, Shiming and Gliessman, 2016, Edmilson José et al, 2013, Trento Filho, 2010, Gana and Busari, 2003, Roodagi et al, 2001a.

“…While intercropping can increase crop yield and profitability where both crops are harvested (Brooker et al, 2015, Kaur et al, 2016, Yang et al, 2013, Parsons and Be, 2003, Kwong et al, 1996, legumes in our study were examined solely as a potential source of N for sugarcane to address environmental concerns. It has been argued that the success of sugarcane-legume systems is largely determined by factors that include the capacity of legumes for BNF, water availability and planting time of legumes ( Gana andBusari, 2003, Roodagi et al, 2001b). For example, legumes did not establish well in sugarcane older than three old months at the time of legume planting due to competition (Billore et al, 2000).…”

“…While sugarcane-legume intercropping is successful in some circumstances, in others a negative or no effect on sugarcane yield was observed (Geetha et al, 2015, Gana and Busari, 2003, Roodagi et al, 2001b. Sugarcane yields were suppressed in a sugarcane-soybean/lupin (Glycine max/Lupinus albus) intercrop at N fertiliser N rates of 0, 33, 67, and 100% of the full N rate (Ramouthar et al, 2014).…”

Developing sugarcane - legume companion cropping systems to minimise nitrous oxide emissions

Global efforts are underway to reduce greenhouse gas emissions (GHG) from anthropogenic activities. Nitrous oxide (N2O) emissions accounted for 13% of Australia's National GHG inventory over the period 2016-2017 (NGGI, 2017) with most N2O derived from agricultural soils. Sugarcane soils are high emitters of N2O, and this thesis explores whether legumes, grown as a companion crop with biological N2 fixation (BNF) capacity, can partially replace N fertiliser to lower the emissions of N2O from sugarcane soil. Chapter 2 synthesises published literature on sugarcane intercropping. Most research has focussed on the productivity of sugarcane with intercrops, including legumes. Intercropping can benefit sugarcane yield, have neutral or negative effects. This practice is common in subsistence agriculture, and farm income benefits, but environmental benefits intercropping have not been a research focus. Chapters 3 and 4 explore sugarcane-legume intercropping at three commercial farms in Australia. N2O emissions, soil and crop variables were quantified with different N fertiliser applications and in the presence or absence of legumes. The farms, two Rain-fed, one Irrigated, were located in the dry and wet tropics, and in the subtropics, representing different climate and agronomic settings. Industry-recommended (full) N fertiliser rates were compared with up to 50% reduced N fertiliser rates in the presence or absence of legume and benchmarked against a zero N fertiliser control. We hypothesised that reduced application of N fertiliser limits sugarcane growth and that legumes can alleviate N limitation. However, full and reduced N fertiliser treatments mostly generated similar sugarcane yields, confirming that industryrecommended full N fertiliser rates exceed sugarcane needs. In line with this notion, the reduced N+legume treatments did not improve sugarcane growth. N2O emissions in reduced N+legume were either similar to reduced N fertiliser sugarcane monoculture or higher and similar to the emissions observed with full N fertiliser rates. Soybean strongly benefitted sugarcane yield under N limiting conditions (zero N fertiliser) at one farm, increasing soluble soil N levels and nearly doubling sugarcane yield compared to zero-N sugarcane monoculture, and generating 6-times lower N2O emissions than the full N rate. At the Rain-fed sites, soil nitrate levels explained 81 and 64% of N2O emissions; at the Irrigated site, the interaction of soil nitrate and soil moisture explained 63% of N2O emissions. High N2O emissions factors at the subtropical site were associated with wet, low drainage soil (>70% water filled pore space over summer), conditions that promote denitrification. High N fertiliser rates in Irrigated, welliii draining soils had lower N2O emissions, possibly shifting N losses from gaseous to leaching. The promising findings observed with soybean under N limitation require further investigation to explore N2O mitigation options with a view of optimising legume facilitation and the 'tipping point' for N fertiliser...

Field trials were conducted to determine the optimal rate of nitrogen (N) for chewing sugarcane production in the Southern Guinea Savanna of Nigeria at the upland sugarcane experimental field of National Cereals Research Institute Badeggi (9°45'N, (06°7'E) in 1998 and 1999 wet seasons. In both the years 60kgN/ha resulted in significantly reduced lower growth parameters (germination percentage, tiller count, stalk length and yield tonne / ha). While among the four rates of 120, 180, 240 and 300kgN/ha there was no significant difference as the growth parameters and yield were significantly comparable.
