Field trials were conducted in savanna ecologies of Nigeria during the 2015 and 2016 seasons using maize (PVA8) and soybean (TGX 1448-2E) intercropping systems with different fertilizer rates to evaluate the yield of maize and assess the best intercropping system for resource management. Single plant stands and two plants/stand and 2 arrangements of rows (one row on a ridge and two rows on a ridge) were used to impose maize plant densities evaluated in strip inter-crop with soybean. The trial was factorial, laid out in a randomized complete block design and replicated three times. Thus, 8 maize-soybean strip cropping systems and application of 3 NPK rates were evaluated at Saki-Oyo, Ilorin, and Nasarawa (southern Guinea savanna), Kaduna in the northern Guinea savanna, Funtua (Katsina) and Gusau (Zamfara) located within Sudan savanna ecologies of Nigeria. Data on yields and yield components were collected. The intercropping systems were assessed using existing intercropping indices such as Land Equivalent Ratio (LER), Relative Crowding Coefficient (K), Aggressivity (A), Competitive Ratio (CR), Actual Yield Loss (AYL), Intercropping Advantage (IA) and Monetary Advantage Index (MAI). The result showed that Nasarawa and Kaduna were most ideal locations for maize production in the Nigeria savannas. The highest grain yield of 4.04 tons/ha maize and 1.36 tons/ha soybean were obtained from seeding 1 plant/stand in 2-rows per ridge x 4 ridges of maize alternated with 2 rows of soybean with the application of NPK at 100:50:50. The LER was 1.11, AYL (1.10) and MAI (208) gave a profit of ₦312,102.00 (US$990.80) ha-1 with a benefit-cost ratio of 2.38 and production efficiency of 29.56%. The study concluded that, seeding 80% maize and 20% soybean per ha will lead to sustainable maize crop production with limited use of fertilizer. It can be adopted by the farmers in Nigeria savannas as a relatively profitable intercropping system.

Field experiments were conducted at faculty of Agriculture teaching and research farm, university of Maiduguri in 2010 and 2011 rainy seasons. The aim was to investigate the impact of intercropping sorghum with okra on the incidence of flea beetle of okra (Podagrica spp) in the semi-Arid zone of Nigeria. The results showed that sole crop okra suffered flea beetle attack which affected its growth, fruit formation, fruit weights and fruit yield. Intercropping okra with sorghum significantly reduced the flea beetle populations, leaf damage caused by Podagrica spp (Coleoptera: Chrysomelidae). While increasing number of leaves for photosynthetic activities, plant height, fruit formation, fresh fruit weight and total fruit yield. The study concluded that okra intercropping at 1:1, 1:2 and 2:2 are the most efficient and productive intercrop systems in flea beetle management. Okra intercropping with cereal sorghum was found to be good for sustainable agriculture and organic farming in Nigeria due to its numerous advantages, particularly with respect to insect pests’ control.

On-Farm trials were conducted from July to November during the 2009 and 2010 cropping seasons, at Tarka, Benue State, Nigeria to evaluate the effects of intercropping maize and soybean on striga control, grain yields and economic productivity. The treatments consisted of sole maize, sole soybean and the intercrop of maize and soybean, replicated three times in a randomized complete block design. The results obtained showed that intercropping maize and soybean significantly (P ≤ 0.05) reduced striga shoot count by 55.9 % and 56.1 % respectively, in 2009 and 2010 compared to that produced on pure maize plots. Number of affected maize plants, lodging score of maize and infestation rate were lower for intercropping than for sole maize plots. The severity level was also recorded lower for intercropping compared to that recorded for pure maize stands, where severity level is in the range of high to very high. Though, soybean yield was reduced by intercropping, however, soybean and maize intercropping system increased maize grain yield, total intercrop yield, land equivalent coefficient greater than 0.25, land equivalent ratio values greater than one (LER > 1), higher total intercrop values and monetary equivalent ratio greater than 1.00, indicating yield and economic advantages. The implication of study showed that intercropping maize and soybean can be adopted by farmers as an efficient cropping system strategy to reduce striga infestation, increase maize yield and give greater economic productivity.

Full textAbstract:
Field trials were conducted during 2011 and 2012 cropping seasons at the Teaching and Research Farm of the University of Agriculture Makurdi, Benue State located in Southern Guinea Savanna of Nigeria. The objective of the study was to evaluate the response of some improved sweet potato varieties planted at three densities to intercropping with soybean. The experiment was a 2x3x3 split-split plot laid out in a randomized complete block design with three replications. The main plot consisted of two cropping systems [sole cropping (sweet potato, soybean) and intercropping (sweet potato + soybean). The sub-plot consisted of three sweet potato varieties (CIP440037, NRSP/05/007C and CIP440141). The sub-sub-plot treatment comprised of three sweet potato planting densities (25,000 plants/ha, 33,000 plants/ha and 50,000 plants/ha). Intercropping severely depressed the yields of both sweet potato varieties and the soybean component, such that intercrop yields were rarely above 50% of sole crop yields, irrespective of the sweet potato variety used. The number and weight of the sweet potato component was not significantly affected at the planting density of 50,000 plants/ha. Indices used to measure intercrop advantage showed that intercropping these sweet potato varieties with soybean was biologically efficient and percentage land saved varied from 23.08 and 32.43. Soybean was more competitive than sweet potato at all densities tested.

A study to determine the financial benefits of intercropping immature rubber plantation with cassava in South Eastern Nigeria was carried out at the Rubber Research Institute of Nigeria, Iyanomo near Benin City. The study was set up in a randomized complete block design with each treatment replicated three times. Yield data generated were used to determine the profitability of the systems. The results showed economic yield from rubber as the rubber trees did not attain tappable girth throughout the duration of the study. a mean yield of about 25.72 tonnes of cassava tuber were generated from the sole cassava treatments for the four years period while a mean yield of about 22.92 tonnes of cassava tuber per hectare were generated from the cassava + rubber intercrop treatments in the same period. A total amount of 160,000 Naira was spent in four years as cost of intercropping. Total revenue generated from the sales of cassava in the rubber + cassava system was 900, 000.00 Naira per hectare with a Gross Margin and profit margin of 740,000 Naira and 673, 090.98 Naira respectively. A profitability index of the rubber + cassava system was 0.75, indicating that, 75% of the total amount invested in the rubber + cassava system was recovered in the first four years compared to the additional costs incurred in the sole rubber plantation treatment. This study showed that intercropping cassava with rubber during the immature phase of rubber plantation guarantee early return on investment and more profitable compared with sole rubber plantation systems.

SUMMARYInsect infestation and damage in cowpea (Vigna unguiculala), planted sole or intercropped with tomato (Lycopersicon esculentum) was monitored in 1987 and 1988 in Akure, Nigeria. Infestation of cowpea byEmpoasca dolichiwas significantly reduced by intercropping with tomato in both years, except in the early season of 1988. Infestation of cowpea byOotheca mutabilis, Aphis craccivora, Megalurothrips sjosledti and Maruca testulaliswas not affected by intercropping with tomato in either year. Damage by pod-sucking bugs and Heliothis armigera was significantly higher in sole cowpea than in cowpea intercropped with tomato, in both years. Sole cowpea had a significantly lower seed yield than cowpea intercropped with tomato.Observaciones en cuanto a la infestación de insectos y daños en el caupí(Vigna unguiculata)sembrado en forma simultánea con tomate(Lycopersicon esculentum)en una zona de bosque tropical en Nigeria

Field experiments were conducted from July to November during the 2012 and 2013 cropping seasons, at the Research Farm, University of Agriculture, Makurdi, Nigeria, to evaluate the yields of two newly introduced sesame varieties (Ex Sudan and SN 603) against the commonly grown variety “E-8” under intercropping with maize variety ‘Oba 98’. The trial area consisted of a total of seven treatments, replicated three times in a randomized complete block design. The results showed that, though maize yield was not significantly (P ≤ 0.05) affected by intercropping with sesame varieties, however, intercropped yield of sesame variety ‘Ex Sudan’ was significantly (P ≤ 0.05) greater by 26.8 % and 25.6 % respectively, in years 2012 and 2013, compared to that obtained from intercropped sesame variety ‘SN 603’, and by 19.5 % and 20.9 % respectively, in years 2012 and 2013, compared to that produced from intercropped popular sesame variety ‘E-8’. Intercropping maize variety ‘Oba 98’ with sesame variety ‘Ex Sudan’ gave the highest total intercrop yield, greatest biological efficiency with a relative yield total values of 0.87 and 0.91 respectively, in 2012 and 2013. The combination also recorded the highest land equivalent ratio (LER), highest land equivalent coefficient, highest area x time equivalent ratio (ATER), highest total monetary returns (N584,200 and N588,600 respectively, in years 2012 and 2013) and highest monetary equivalent ratio (MER). The implication of study showed that sesame variety ‘Ex Sudan’ performed best and could therefore be recommended as a potential replacement for the popular variety ‘E-8’ under intercropping with maize variety ‘Oba 98’ in Makurdi, Nigeria.

Full textAbstract:
A field experiment was conducted from August to November, during the 2012 and 2013 cropping seasons at the Research Farm, University of Agriculture, Makurdi, Nigeria, to identify the optimum plant density of okra and intercropping effects on yields of egusi melon-okra mixture and to assess the yield advantages of the intercropping system. The experiment was a 3x3 split plot arrangement of treatments, fitted in a randomized complete block design (RCBD), replicated four times. The intercropping (sole egusi melon, sole okra and egusi melon-okra mixture) constituted the main plots, while the population densities of okra (33,000, 40,000 and 50,000 plants ha-1 equivalent) into egusi melon were allocated to the subplots. Results of study showed that to maximize intercrop yield of okra in an egusi melon-okra intercrop, the optimal population density of okra is 33,000 plants ha-1, while that of 40,000 plants ha-1 is optimal to maximize intercrop yield of egusi melon. Intercropping egusi melon and okra significantly (P≤0.05) reduced yields of egusi melon (37.5 % and 40.5 % respectively, in years 2012 and 2013) and that of okra (9.7 % and 16.9 % respectively, in years 2012 and 2013). The highest mean land equivalent ratio value of 1.57 and highest land equivalent coefficient values of 0.60 and 0.63 respectively, in years 2012 and 2013, were recorded for okra sown into egusi melon at the population density of 40,000 plants ha-1. It is most advantageous having both crops in intercrop when okra is sown into egusi melon at the population density of 40,000 plants ha-1. This should therefore be recommended for Makurdi location, Nigeria.

Full textAbstract:
Cashew is an important economic tree crop cultivated for its wood, apple and most especially the nut. The large plant spacing involved in its cultivation encourages intercropping. Intercropping cashew during the early phase of establishment with arable and sometimes tree crops is usually practiced which serves as food security, cultural weed control and means of additional income to farmers. The aim of this study is to look into some experimented cashew intercrop and gaps in the intercrop patterns. Review of past literatures was used in discovering cashew intercrop patterns in Nigeria and some major cashew producing countries. Intercropping cashew with arable crops is more popular and profitable than with tree crop except in Sri-lanka where intercropping with coconut seems profitable than cashew sole cropping. Intercropping of cashew with arable crops, legumes and vegetables did not affect the growth of young cashew except millet, sorghum and pigeon-pea. Cashew/maize and cashew/cassava/yam had high returns respectively. Intercrop combinations with more than two crops affected the growth of cashew. Cashew/rice and cashew/plantain intercrop suppressed the growth of weeds with no negative effect on cashew growth. More concise and implementable research can be done where information on weed control, growth parameters, nutrient demands, yield and economic returns can be gotten from an experiment on the various cashew intercrop patterns as this will make the findings more adoptable by the farmers. Intercropping cashew with more than 2 crops should be discouraged.

Full textAbstract:
The primary hypothesis of this research was that improved cowpea genotypes (selected under sole crop) could yield well in several Nigerian cropping systems, and that there were cowpea characteristics that improved overall system productivity. Cowpea lines were identified which were high yielding and stable in several management systems. Practices such as not applying insecticide and intercropping both reduced cowpea grain yield significantly. Land equivalent ratios were greater than one for all tested intercrop systems: cassava-cowpea (1.21-2.35), maize-cowpea (1.31-4.23), maize-cassava-cowpea (1.63-3.40) and millet-cowpea (1.13-6.88). Nitrogen nutrition of component crops was investigated. Line influenced both maize grain (12.5-28.4 kg ha-1) and total biomass (48.7-69.0 kg ha-1) nitrogen yield. Evidence from pot and field experiments (including $ sp{15}$N-dilution studies) indicated same-season nitrogen transfer. Light interception studies also indicated the increased light harvesting ability of early sole cowpea lines compared to early intercropped lines systems.

Full textAbstract:
The use of chemical fertilizers as a supplemental source of nutrients has been on the increase but they are not applied in balanced proportion by most farmers [1]. Also, fertilizer requirements of the mixed intercropping systems have been a matter of conjecture; some studies had suggested that fertilizer requirements of the dominant component be applied [2], others recommend that the sum of the sole crop requirements, be applied [3]. Teriah [4], however, stated that both practices have proved either inadequate or wasteful. In this experiment the effects of different rates of NPK 15-15-15 fertilizer application on growth and yield of hot pepper and Egusi melon in an intercropping system was examined to determine optimum rate for production. The experiment was carried out at the Teaching and Research Farm of the Federal University of Agriculture Abeokuta, in the south western part of Nigeria. It took place from March to October 2017 during the growing season. The experiment was laid out in a Randomized Complete Block Design (RCBD) with 5 treatments (fertilizer rates) and 3 replicates. Treatments were; 0, 100, 200, 300 and 400 kg/ha of NPK 15-15-15 applications. Plot size was 3m by 3m with a 1.5m gang way round each plot to reduce inter-plot effect. Data were collected on growth parameters at 6 weeks after treatment (WAT) and continued at two-week intervals until 10 WAT. Four plants each of pepper and Egusi melon from the inner rows were randomly selected and tagged for the purpose of data collection. Data on yield were also collected at ripening. Analysis of variance (ANOVA) was carried out on each observation and the Least Significant Difference (LSD) was used for means separation (P≤0.05). The effects of fertilizer rates showed significant difference on pepper plant height, number of leaves, number of branches and leaf area. However, there was no significant difference in the effect of fertilizer rate on days to 50% flowering of pepper. Number of vines and vine length of Egusi melon were significantly different in their responses to fertilizer rates but the leaf area and days to 50% flowering of melon were similar at the various treatment levels. Meanwhile, total fruit yield of pepper, number of Egusi melon pods per hectare and the dry matter yield of Egusi melon showed significant difference. It was concluded from the study that the growth and yield of pepper and Egusi melon in intercrop increased with increase in fertilizer rate up to 400Kg/ha of NPK (15:15:15). However, higher fertilizer application rates should be explored in future studies for a better yield increase. These studies should be carried out with various compositions of inorganic and organic fertilizer application rates to ensure sustainable fertilizer application and to also preserve the natural fertility of the soil.
