Potential of Integrated Nutrient Managements (INM) on Nutrient Uptake (N, P and K) by Chickpea

Abstract

This work estimated the potential uses of NPK by chickpea under using of different combination of bio-fertilizer. The field experiment was conducted at Research Field, Department of Soil Science, JNKVV, Jabalpur (M.P.). The field is located in the south-eastern part of Madhya Pradesh at 23013’ North latitude, 790 57’ East longitudes at an altitude of 393 meter above the mean sea level. The experimental field was well-drained with levelled topography. The experiment was carried out on chickpea (JG-14). The experiment was consists of three main-plot treatments of NPK and six sub-plot treatments of vermicompost and biofetilizers which were replicated three times in a split plot design (SPD) with treatments error was P>0.05 value during analysis. The results revealed that the INM influence directly on NPK (nitrogen, phosphorus and potassium) uptake. The treatment 100% NPK (65.08 and 26.39 kgha-1) with combination vermicompost and Rhizobium+ PSB+KSB+ Trichoderma (biofetilizers) (61.77 and 27.45 kgha-1) highest nitrogen uptake. Phosphorus uptake estimated maximum in treatment of 50% NPK (7.24 and 4.03 kgha-1) with combination vermicompost and biofetilizers (10.03 and 4.92 kgha-1) moreover potassium uptake found highest in 100% NPK (5.10 and 27.11 kgha-1) with vermicompost and biofetilizers (4.92 and 27.80 kgha-1) in grain and stover respectively.
