“…This could be attributed to the wood ash applied to the plots and subsequently its competitive abilities were enhanced. Egbe (2005), had observed similar results in pigeon pea/maize intercropping systems and ascribed this superiority to height and biomass production advantage of the cereal component. Leaf area is a measure of size of assimilatory system of plant and is a product of leaf length and width.…”

Wood ash generated from wood industries have enormous potential which can be utilized due to its properties which influences soil chemistry and fertility status of tropical acidic soils. Field experiments were conducted on an acidic sandy loam alfisol to investigate the effects of wood ash on the growth indices and chlorophyll content of maize and lima beans intercrop during the late and early seasons of 2014 and 2015 at Akure in the rainforest zone of southwestern Nigeria. The treatments were 100% sole maize with ash, 100% sole maize without ash, 75% maize + 25% lima beans with ash, 75% + 25% lima beans without ash, 50% maize + 50% lima beans with ash, 50% maize + 50% lima beans without ash, 25% maize + 75% lima beans with ash and 25% maize + 75% lima beans without ash. Wood ash was applied at 2.4kg/plot. Wood ash increased chlorophyll content in all amended treatments except in amended 25:75% maize-lima beans intercrop and 25:75% maize -lima beans intercrop without ash, however 75:25% maize-lima beans amended with wood ash significantly (P≥0.05) recorded the highest chlorophyll content. Growth parameters such as plant height, number of leaves, leaf area, leaf area index, leaf length, stem diameter, number of flowers, number of pods, weight of plant and total biomass of amended maize-lima beans intercrop were significantly (P≥0.05) increased by wood ash application. Based on experimental findings, 25:75% maize-lima beans intercrop and 75%:25% maize-lima beans intercrop amended with wood ash was concluded to be more recommendable in the study area.

“…Because adequate fertilizer was applied, maize plant height and biomass production were accelerated and subsequently its competitive abilities were enhanced. Egbe (2005) had observed similar results in pigeon pea/maize and pigeonpea/sorghum intercropping studies at Otobi and ascribed this superiority to height and biomass production advantage of the cereal component. The LER (>1) and LEC (>0.25) values obtained in this study proved that intercropping was advantageous.…”

A field experiment was conducted in 2010 and 2011 at the Teaching and Research Farm, FederalUniversity of Agriculture, Makurdi, Nigeria. The aim was to determine the suitability of some landraces of bambara groundnut for intercropping at varying planting densities with maize. The experiment was a 2×3×3 split-split plot laid in a randomized complete block design with three replications. Intercropping decreased number of pods and grain yields of bambara groundnut component. Number of pods and grain yields increased with increased planting density. Productivity indices indicated that bambara groundnut/maize intercropping was productive, and maize was the dominant component. The marginal rate of returns for the best combinations was 116.13%, suggesting profitability of the intercropping systems.

“…These findings are comparable to other studies. Leaf physiology, plant growth, and yield often vary dramatically among different varieties planted in different locations (Akinola and Oyejola, 1994; Egbe and Idoko, 2012). Nam et al (1998) reported that LAI can reach 5 to 6 for some extra‐short‐duration pigeonpea varieties grown in India.…”

“…They also found that seed yield could vary remarkably. Egbe and Idoko (2012) observed that the mean grain yield of 15 pigeonpea varieties was 2050 kg/ha, and ranged from 1380 kg/ha to 3110 kg/ha. In another study, the mean yield was 1660 kg/ha and ranged from 920 to 2850 kg/ha (Egbe and Idoko, 2012).…”

As the demand in the United States for legume crops such as pigeonpea [Cajanus cajan (L.) Millsp.] increases, it becomes increasing important to improve yield and extend the area where pigeonpea may suitably be grown. To understand the effect of agricultural management on the leaf physiology, growth, and yield of pigeonpea, a 3-yr (2010-2012) field experiment was conducted in Nashville, TN. A split-split-plot experimental design with two planting dates in years 2010 and 2012, and one late planting in 2011 were used (main plot factor, early and late planting). Four pigeonpea varieties (subplot factor, GA1, GA2, W1, and W3) at three plant densities (sub-subplot factor, 295,500, 145,250, and 96,833 plants/ha) were planted. Maximum leaf photosynthesis, stomatal conductance, transpiration, plant height, plant stem diameter, leaf area index (LAI), and seed yield were measured. There were significant differences in leaf physiology, growth and yield among varieties, between planting dates, and between years. Leaf transpiration (5.4 mmol H 2 O/m 2 /s) and yield (1048 kg/ha) were higher at early planting than at late planting (4.8 mmol H 2 O/m 2 /s, 2.64, and 629 kg/ha), but height (138 cm) was lower at early planting than at late planting (150 cm). Among varieties, GA2 plants were shorter (131 cm) and had lower LAI (1.61), but produced higher seed yield (1263 kg/ha). Plant density did not show significant influence on leaf physiology, LAI, or yield. All variables measured showed remarkable variation between years. Our results indicated that variety selection and early planting may improve pigeonpea growth and yield in middle Tennessee.
