Abstract:
An experiment was conducted to study the “Impact of different sources and levels of iron on yield and quality of groundnut [Arachis hypogaea (L.)].” at Mangulam village of Mangalor block, Cuddalore district, Tamil Nadu. Total eleven treatments were tried in Randomized Block Design (RBD) with three replications. The treatment consisted of different sources and levels of Fe. Soil application of 50 kg Fe-EFYM along with Bacillus subtilis @ 2 kg ha^-1 and RDF (T₇) recorded significantly the higher number of pods per plant (38.67), 100 kernel weight (48.69 g), pod yield (2060 kg ha^-1), haulm yield (2891 kg ha^-1), oil yield (966 kg ha^-1) and protein content (14.5%) followed by soil application of 37.5 kg Fe-EFYM along with Bacillus subtilis @ 2 kg ha^-1 and RDF (T6). It was also observed that, the oil content was not influenced due to soil and foliar applied iron treatment alone or in combinations.
