Effect of integrated nutrient management on soil fertility and yield of maize crop (Zea mays) in Entic Haplustart in Tamil Nadu, India
Journal Title: Journal of Applied and Natural Science - Year 2014, Vol 6, Issue 1
Abstract
A field experiment was conducted to study the integrated use of organic and inorganic fertilizers on the soil fertility status of Entic Haplustart in maize at Malayalathanpatti village, situated at Madurai district during Kharif season of 2008-2009. The experiment was conducted in Randomized Block Design with three replications in Annaiyur soil series (Entic Haplustert). The results revealed that highest grain yield of 4402 kg ha-1 was recorded in treatment that received vermicompost @ 5t ha-1 with 75 percent Recommended dose of fertilizer (RDF) and it was found to be superior to over treatments. Application of vermicompost @ 5t ha-1+75 percent RDF recorded the highest calcium and magnesium content in pot harvest soil sample (0.139 and 0.281%). And also increased the crude protein (16.67 %) and starch (81.34 %) content in maize crop and it was followed by the treatment which received sewage sludge 2t ha-1 with 75 percent RDF (Recommended dose of fertilizers) and green leaf manure @12.5t ha-1whereas the lowest value was recorded in control plot respectively. The vermicompost along with inorganic fertilizers were efficiently used by maize crop for their growth and development and also maintainined soil fertility and increased yield of the crop.
