dc.description.abstractA pot experiment was conducted to study the efficiency of zinc enriched organic manures with other manurial treatments the yield and chemical compositidn of maize at the Agricultural Chemistry and Soil Science department, Gujarat Agricultural University, Anand Campus, Anand taking fodder maize (Zea mays L.) cv. Gujarat Maize-3 as a test crop during summer season of 2000 on loamy sand soil (Typic Ustochrept). Nineteen different treatments were given, using recommended dose of fertilizer and organic manures viz. Farmyard manure, castor cake, poultry manure and biogas slurry enriched with 25 and 12.5 Kg ZnS04 ha-1 The experiment was laid out using complete randomised design with three replication. The green and dry matter yields were recorded and fodder was analysed for chemical constituents. The soil samples were collected at 30 DAS and after harvest of crop and were analysed for the fertility status. The present study revealed that the application of 50 % N through fertilizer + 50 % N through poultry manure enriched with 25 Kg ZnSO4 ha-1 produced the highest green matter yield but it was at par with biogas slurry, castor cake and poultry manure applied with 25 Kg ZnS04 ha-1 Significantly the highest dry fodder yield was recorded under poultry manure enriched with 25 Kg ZnS04 ha-1. The highest dry root weight values were recorded with same treatment. Application of poultry manure enriched with 25 Kg ZnS04 ha-1 proved to be the best in case of N, K and Zn content and uptake. The highest S content was recorded with RDF + SO4 equivalent to treatment N0.-2. However, differences among the treatments were non- significant in P and Cu content of fodder maize. The maximum removal of N, P, K, S, Zn, Fe, Cu and Mn were observed when poultry manure enriched with 25 Kg ZnS04 ha-1 In root study the variation in N, P and K content and root CEC values were found to be non-significant, while the uptake of N and K were significantly influenced by poultry manure enriched with 25 Kg ZnS04 ha-1 The highest Zn content and uptake values were obtained with the same treatment. While studying the fertility status of the soil after harvest, it was noted that the soil pH, EC, WHC, bulk density, porosity, CEC, available P, K, Cu, Mn content of soil were found to be non-significant, while the organic carbon content, total and available N, available S and available Zn contents were the highest values with the poultry manure enriched with 25 KgZnSO4ha-1 Therefore, it was observed that the application of poultry manure enriched with 25 Kg ZnSO4 ha-1 improved the crop quality and soil fertility as well as sustained the productivity of soil. From the above results and discussion it could be concluded that the application of poultry manure enriched with 25 Kg ZnS04 ha-1 prove to be the best treatment for the best yield and quality of fodder maize on loamy sand soil. It also maintains the fertility of the soil.en_US
