A comprehensive field experiment was conducted to study the â€œVarious Impact of different sources of Liming materials on Growth, Yield and Productivity of the Maize crop Grown in Acid soil of Odisha â€ in the village Bajpur, Haladia, Andharua, Mendhasal in khorda district of Odisha during Kharif, 2013.The soil was ameliorated with three different source sof liming materials (paper mill sludge @ 0.1LR, Stromatolyte @ 0.1 & 0.2 LR and Calcium Silicate @ 0.2 LR)added with soil test based dose with or without FYM. The FYM integrated treatments maintained higher chlorophyll content (SPAD values) than FYM untreated one. However use of liming materials did not influence the recorded chlorophyll content (SPAD values) much in the crop. The calcium silicate source applied @ 0.2 LR and the ST @ 0.2 LR when applied mixed with FYM recorded highest average growth rate of 3.9 cm day-1. Liming of soil and their combined application with FYM resulted in increasing root length, cob length, diameter and seed weight cob-1 respectively. Inorganic (Lime) amelioration of acid soil resulted in 32 per cent higher yield compared to the yield of 22 qha-1 due to inorganic nutrition only. Combining organic amelioration (FYM) with inorganic amelioration measure and inorganic nutrition yielded 26 per cent higher grain yield in maize crop. Irrespective of the sources, the stromatolyte @ 0.2LR mixed with FYM produced higher grain (39.3 q/ha) and stover (31.3 q/ha) yields with higher relative agronomic efficiency (234).
