“…High nutrient supply, especially of N, in these plots may have had a depressive effect on nodule number. Olayinka et al (1998) also observed that higher levels of applied garbage compost and cow dung depressed the number of nodules in cowpea. The proportion of total nodules: active nodules is shown in Fig.…”

“…Hence, in contrast to the finding that the number of rhizobium was not significantly affected by organic modifications ( Danso and Alexander 1974), rhizobium was found to benefit from the addition to the soil of small amounts of manure ( Adebayo 1985). Also, Olayinka et al (1998) found that organic modifications would benefit N 2 fixation in soils low in indigenous organic matter. An adequate supply of mineral nutrients to legumes enhances N 2 fixation.…”

In a 3‐year experiment on a Typic Haplustert low in soil test sulphur (S), the response to applied farmyard manure (FYM) and S was studied in terms of the nodule production, nodule dry weight, chlorophyll content, dry matter production and seed yield of soybean. FYM was applied to soybean at four levels (0–16 t ha−1). S as gypsum was also applied at four levels (0–60 kg ha−1) to both soybean and wheat every year. Both total and active nodule production, nodule dry weight, dry matter production and seed yield of soybean were increased significantly by the application of both FYM and S. However, the proportion of total nodules to active nodules fell sharply for applications higher than 8 t FYM and 40 kg S ha−1.

“…The potential of cow dung, poultry droppings, refuse compost and farmyard manure as suitable soil amendments in the tropics has been reported [1,2,3,4]. Application of organic materials as fertilizers provides growthregulating substances and improves the physical, chemical and microbial properties of the soil [5,6,7,8].…”

High and sustainable crop yields in the tropics have been reported to be only possible with judicious combination of mineral fertilizers and organic amendments. Fertilizing croppings to achieve this has usually been a difficult task to achieve. The growth and yield of maize cultivated with a complementary application of organic and inorganic fertilizers was assessed compared with sole organic and sole inorganic fertilizers between April and July 2003 and 2004 at Ibadan, Nigeria, in the degraded tropical rain forest zone. There was a no-fertilizer treatment as the control. The organic fertilizer was an equal mixture of composted domestic waste and stale cow dung, applied at 10 tonnes ha -1 . Urea and Single super phosphate were applied as the inorganic fertilizer to supply 70 kg N and 13 kg P 2 O 5 ha -1 respectively. The mixture of organic and inorganic fertilizer treatment consisted of half the rates used for sole organic and sole inorganic fertilizer treatments: 5 tonnes organic mixture was applied, with 35 kg N and 6.5 kg P 2 O 5. Maize plant height at 8 weeks after planting was highest with inorganic fertilizer application while the leaf area was highest with organic fertilizer application. Stover yield and cob yields were also highest with inorganic fertilizer. Complementary application of organic and inorganic fertilizers however had similar plant heights; stover yield as well as cob yields with inorganic fertilizer. Nitrogen appeared chelated with organic fertilizer application. Plant earleaf Nitrogen was highest (1.68%) with inorganic fertilizer while the control plots had a Nitrogen content of 1.12% which was higher than 0.84% and 0.98% N from sole organic and a complementary application of organic and inorganic fertilizers, respectively. Plant P content was increased by 136% and 15% with organic and inorganic fertilizers, respectively, but was reduced by 15% with complementary application of organic and inorganic fertilizers. The K content was highest with inorganic fertilizer (1.91%). Complementary application of organic and inorganic fertilizers had a K content of 1.70% while the organic -fertilized leaves had 1.53%. Stover nutrient uptake was highest for N and K with inorganic fertilizer while the P was highest with organic fertilizer application. Cultivating maize with complementary organic and inorganic fertilizers gives a comparable cob yield as inorganic fertilizer and has nutrients higher than from sole organic fertilizer application.

“…Reijnties et al (1992) and Adepetu (1997) remarked that the downward trend in food production should prompt farmers to amend the soil with different materials in order to enhance growth and yield of crops. Several organic materials such as cattle dung, poultry dropping, pig dung and refuse compost have been recommended to subsistence farmers in West Africa as soil amendments for increasing crop yield (Sobulo & Babalola, 1992;Ismail et al, 1999;Olayinka, 1996;Olayinka et al, 1998). Zougmore et al (2006) reported that poultry dropping and cattle dung increased root growth of maize and the crop extracted soil water more efficiently for increased grain yield.…”

This study was carried out in the Teaching and Research Farm of Delta State. University, Asaba campus (Nigeria) from March 2008 to June 2010 to evaluate the nutrient content (% dry matter) of maize as affected by different levels of organic manure and inorganic fertilizer. The experiment was carried out in a Randomized Complete Block Design (RCBD) replicated three times in a factorial layout. Four different rates of poultry droppings, cattle dung and NPK 20: 10: 10 fertilizer were applied to three maize varieties sown at 75 cm x 15 cm spacing and the maize grains produced were evaluate for their nutrient content in percentage dry matter. The results obtained indicated that hybrid variety 9022-13 had the highest N, P and K contents (1.03, 1.68 and 0.26, respectively). Also, plants that received inorganic fertilizer had the highest values of 1.27% N, 1.64% P and 0.29% K. Based on rates of application, plants that received 450 kgha -1 NPK 20: 10: 10 fertilizer had the highest values of 1.74% N, 1.71% P and 0.49% K. The interaction effects showed that only variety, manure type and rates % application were significant (P < 0.05). Based on this study, it is recommended that (i) Hybrid variety, 9022-13, which was outstanding in its nutrient content be grown in the study area. Alternatively, farmers who prefer open-pollinated varieties could grow BR 9922-DMRSF 2 or Agbor local variety for people who prefer local varieties in maize production (ii) Spacing of 75 cm x 15 cm (88, 888 plants/ha) which resulted in better growth performance and yield should be adopted in maize production (iii) Farmers who prefer mineral fertilizer for increased growth and yield of maize should apply 450 kg ha -1 of NPK 20: 10: 10 (iv) Farmers who practice organic agriculture in Asaba agro-ecological zone should apply 30 tha -1 of poultry manure to enhance maize yield.
