dc.description.abstractThe present investigation was undertaken to study the comparative efficiency of Zn and Fe enriched FYM on crop yields and nutrients removal under mustard (var. GM-2) - sorghum(var. S-1049) crop sequence. The enrichment was carried out with two levels of Zn (2.5 and 5.0 kg) and Fe (5 and 10 kg) by composting the locally available farm yard manure (FYM) at 500 kg ha-1 for seven weeks as required to complete the enrichment process. The enriched FYM was used for field experiment on the pre-identified Zn and Fe deficient site at Forage Research Project Farm, GAU, Anand. The treatments of Zn and Fe enriched FYM were evaluated as against straight Zn and Fe application at corresponding rates through inorganic fertilizers in conjunction with FYM at 0, 5 and 10t ha-1 In order to evaluate the effect of S, an additional treatment was also kept to supply S at 20 kg ha-1. The average increase in the seed, straw and total yield due to FYM application was higher by 184, 356 and 539 kg ha-1 respectively over no FYM. The Zn and Fe enriched FYM improved average mustard seed yield by 20 per cent over control whereas it was higher by 11 per cent over straight Zn and Fe application. It was noticed that there was no significant difference in mustard yield due to level of Zn and Fe enrichment and FYM levels. The average yield increase in dry matter of sorghum by 11 per cent was observed due to residual effect of FYM over control The overall maximum improvement in sorghum dry matter due to Zn and Fe enriched FYM was higher by about 9 per cent over straight Zn and Fe application. The residual effect of FYM at10 t ha-1 and Zn and Fe enrichment at 2.5 and 5.0 kg ha-1 was found more beneficial to increase sorghum fodder yield. Further, the nutrients removal was found higher under Zn and Fe enriched FYM treatments. Further, mustard seed quality parameters viz. oil, protein and potential oil yield were found improved under treatments of Zn and Fe enrichment compared to straight application of Zn and Fe. In general, the effects under both the levels of enrichments on different parameters in mustard were more or less similar which indicated to lower down the Zn and Fe supplementation dose by one half of the recommended quantity of 5 and 10 kg ha-1 respectively. The application of S alone was also found beneficial; however, the response by the crops was increased when Zn and Fe application was made after their enrichment along with FYM at 10 t ha-1 The Zn and Fe enriched FYM application either maintained or improved the soil fertility status. The Zn and Fe enriched FYM enhanced availability of most of the nutrients especially available N, S and DTPA-extractable micronutrients like Fe, Zn, Mn and Cu after mustard. Thus, the overall findings suggested the importance and practical utility of the Zn and Fe enrichment technique for organics in integrated nutrient management to maintain fertility and crop productivity of the Zn and Fe deficient soil, besides reduction in use of inorganic fertilizers of the micronutrients.en_US
