| Popis: | Chickpea (Cicer arietinum L.) is the most important and ancient pulse crop being traditionally grown during rabi season and cultivated mainly in semi-arid regions. The content of iron and zinc in the soil of Regional Agricultural Research Station (RARS) is below the critical level. A field experiment to study the effect of iron and zinc nutrition on growth, yield and nutrient uptake by chickpea conducted in the vertisols of the Regional Agricultural Research Station (RARS), Vijayapur during rabi 2017-18. The experiment was laid out in randomized complete block design with ten treatments and three replications. The treatments included RPP (Recommended package of practice) and application of iron @ 2, 4 and 6 kg ha-1 and zinc @ 2, 3 and 4 kg ha-1 in combinations along with RPP (RDF (Recommended dose of fertilizer) @ 10:25:00:: N : P2O5 : K2O kg ha-1). The results of the experiment revealed that, the application of iron and zinc in combinations resulted in significant increase in growth, yield and nutrient uptake by chickpea over RPP alone. Among the different treatments RPP + 6 kg Fe ha-1 + 4 kg Zn ha-1 was resulted in the maximum test weight (28.28 g), seed (2065.4 kg ha-1) and straw (1734.9 kg ha-1) yield. Similarly, higher protein content, uptake of nutrients (Fe and Zn) by the crop and residual iron and zinc status in soil were recorded due to the application of RPP + 6 kg Fe ha-1 + 4 kg Zn ha-1. These results were at par with the application of RPP + 6 kg Fe ha-1 + 3 kg Zn ha-1 and lower values were recorded in the treatment that received RPP alone. Finally it could be concluded that the application of fertilizers containing iron and zinc helpeds to improve crop yield, protein content and nutrient uptake by chickpea crop and residual soil fertility in terms of iron and zinc. |
