Abstract:
A field experiment was conducted during zaid season of 2020 at SHUATS Crop Research Farm (CRF), Department of Agronomy, SHUATS, Prayagraj (UP) on sandy loam soil so as to evaluate the effect of iron and molybdenum on growth and yield of groundnut. The treatment consisted of 3 levels of Iron viz., FeSO₄ 15 kg/ha soil application, 1% FeSO₄ foliar spray and 7.5 kg/ha soil application + 1% FeSO₄ foliar spray and 3 levels of Molybdenum viz., (NH₄)₆Mo₇O₂₄ at 0.5 kg/ha, (NH₄)₆Mo₇O₂₄ 1.0 kg/ha and 1.5 kg/ha. The experiment was laid out in randomized block design with ten treatments replicated thrice. Study revealed that with application of 7.5 kg/ha FeSO₄ soil application and 1% FeSO₄ foliar spray + 1.5 kg/ha of (NH₄)₆Mo₇O₂₄ recorded significantly higher plant height (60.20 cm), number of nodules/plant (50.66) and maximum plant dry weight (57.80 g) at harvest stage as compared to other treatment combinations. The treatment with application 7.5 kg/ha FeSO₄ soil application and 1% FeSO₄ foliar spray + 1.5 kg/ha of (NH₄)₆Mo₇O₂₄ also recorded significantly higher number of pods/plant (16), number of kernels/pod (2.13), grain yield (2940.97 kg/ha) and haulm yield (4400.93 kg/ha) as compared to all the treatment combinations.
