Effect of nitrogen and poultry manure on yield and nutrients uptake by maize (Zea mays)

Abstract

From this study we can conclude that significantly increase the yield of maize due to integrated nitrogen management could be further attributed to increased growth and vigour of plant as evident from increased growth attributes. So, the treatment combinations (T10) of 125 kg/ ha Nitrogen through inorganics plus 10 t/ha poultry manure through organics were having significant difference as compared to all other. This might be due to ready supply of nutrients through inorganic in the initial stages of crop growth and slow release of nitrogen and steady supply of other nutrients over an extended period of crop growth by organics. Organics have a priming effect on the release of nitrogen from inorganic fertilizer. Moreover, thoroughly decomposed organics were used in these treatments which might have mobilized native nutrients from soils. Poultry manure showed higher yield and yield attributing characters due to faster mineralization of nitrogen with its narrow C:N ratio (15:1-20:1) as evident by its chemical composition. The proper dose of poultry manure can be used as a source of organic manure for sustainable maize production.

“…The results in table (8) showed that there are significant effects between chemical fertilizer levels compared with control on yield g plant⁻¹, the highest value was from 50% of recommended chemical fertilizer application(84.99 g) where's the lowest was from control (72.50 g ) with the rate of increase 17%, also in type and levels of organic The interaction between chemical fertilizer levels, types and levels of organic fertilizers affected significantly (p ≤ 0.05) on yield (g plant -1) , the highest value (104.5 g) obtained from interaction ( 50% of recommended chemical fertilizer and 4 ton ha -1 of domestic organic fertilizer ) and the lowest value (49.1 g) obtained from control of chemical and two types of organic fertilizers, with the rate of increase 112.8% These results agree with [34] on maize plants that they found an increase of yield by increasing of nitrogen and poultry manure levels. *P.M.=poultry manure.…”

INSTANTANEOUS CONVERSION of AGRICULTURAL PLANT RESIDUES as ORGANIC FERTILIZER and it APPLICATION on MAIZE CULTIVATION: A COMPARATIVE STUDY with NPK AND MANURE.

“…And Nitrogen is essential for the growth and development of maize plants. It is an important component of chlorophyll, the pigment responsible for photosynthesis, and amino acids, which are the building blocks of proteins [38]. The result obtain is in line with [25], where sugarcane waste straw biochar, in comparison with Farm Yard Manure and NPK, significantly improved okra plant growth and yield parameters over the control, FYM and NPK.…”

“…There was no much difference between maize D and Maize E, although no sign of grain was observed in maize E as it still looks to be developing at that moment but the cob was a bit bigger and taller to that of maize D, this is probably due to the slow release of the nutrient present in the rabbit manure and insufficient nitrogen and phosphorous, as adequate nitrogen supply is essential for optimum maize growth and yield potential. According to a study by [38], nitrogen application significantly increased the grain yield and biomass production of maize plants while phosphorus is important for root development, seedling growth, and flowering [40]. Maize B despite being the tallest plant among all, have an average yield when compared to maize A and maize C, it maturity was fast compared to the two, this is clearly due to the imbalance of nutrient mostly inadequacy in nitrogen because potassium is important for the development of strong stems and roots and maize cobs [41].…”
