The effects of organic and inorganic
Further, these results are also in concurrence with Negassa et al.
Keeping all these aspects in consideration, the present study was therefore conducted to evaluate the effects of organic and inorganic manures on growth and yield of maize and to assess their residual impacts on soil properties.
Mean values recorded for the above parameters in leaf sample were 3. After air drying and grinding, it was passed through 2-mm sieve and following soil properties were determined: i soil bulk density, ii soil organic carbon, iii Soil pH, iv total N, P, K contents, and v cation exchange capacity, according to methods devised by Sparks Nitrogen was supplied in the form of ammonium sulphate, phosphorus as single super phosphate and potassium as murate of potash.
Wheat Triticum aestivum L. Amaranthus spinosus seedlings were raised and transplanted to seedbeds at a spacing of 10 cm by 20 cm and depth of 3 m, one seedling per hole. It was concluded that the continuous application of organic manure plus balanced fertilization with N, P and K for five years significantly increased apple yield and improved apple quality.
Organic Fertilizer Organic fertilizers are natural materials of either plant or animal source, including livestock manure, green manures, crop residues, household waste, compost, and works directly as a source of plant nutrients and indirectly influences the physical, biological and chemical properties of soil  .
However, values for harvest index were highest in T6.
Effect of organic and inorganic fertilizer on plant growth and yield pdf
Organic fertilizer acts as a buffering agent against undesirable soil pH fluctuations  . The results showed that the integrated use of organic manure with inorganic fertilizers not only increased the rice yield but also improved the fertility status of the soil than inorganic fertilizers alone. Figure 3. Field Crops. It is an annual vegetable that is widely distributed in the humid zone of the tropics including Nigerian Assiak et al. Conclusion In crux, application of organic manures has significant influence on maize productivity and soil physico-chemical properties. Sustaining soil fertility and increasing productivity using organic resources alone would be required large amount of organic fertilizer to maintain soil fertility levels in each and every field. Soil Sediment 10, Organic fertilizer enhances soil biological activity and the colonization of mycorrhizae. Mixture of chicken manure and biofertilizer increases the yield of onion and enriched nutrient content in tuber Fatma et al. For instance in Ethiopian about Combination of organic manures might have improved the nitrogen use efficiency, micro and macro nutrient recovery and help in P solubilization and its uptake by the plants and enhanced K availability that in turn resulted in better growth and yield of maize. Organic fertilizer increase root growth due to enhanced soil structure, promoting soil aggregates, enhances cation exchange capacity . Leaf area development in field-grown maize. Sampling and measurement of various parameters Plant height cm , number of tillers per hill, flag leaf length cm , number of panicles per plant, number of grains per panicle, panicle length cm , kernel length and breadth mm , grain weight were recorded from each experimental plot.
