Abstract:
An investigation on “Response of bio-NP consortium along with iron on nutrient content, uptake and quality of kharif pearl millet in inceptisol” under Northern Maharashtra was carried out during Kharif season 2022 at the Division of Soil Science and Agricultural Chemistry, in College of Agriculture Dhule, under Mahatma Phule Krishi Vidyapeeth, Rahuri, Maharashtra. There were 9 treatments each replicated thrice. The experiment was laid out in Randomized Block Design. Pearl millet variety “Phule Adishakti” was grown by adopting recommended package of practices. The result showed that application of 100% NP + bio- NP consortia @ 6 ml + 30 kg ha^-1 FeSO₄ (T₅) recorded highest nitrogen, phosphrous and potassium content in grain of kharif pearl millet i.e., 1.493%, 0.495% and 0.829%, respectively, however it was at par with treatment T₃ (100% NP + bio-NP consortia @ 4 ml + 30 kg ha^-1 FeSO₄). Similar trend was observed in the stover nutrient content of pearl millet crop i.e., 1.121, 0.354 and 1.42%, respectively in treatment T₅. Maximum iron content (52.2 mg kg^-1) was recorded with application of treatment T₅ (100% NP + bio- NP consortia @ 6 ml + 30 kg ha^-1 FeSO₄) followed by T₃ (51.6 mg kg^-1). Similarly, application of treatment (T₅) recorded significantly higher iron content (mg kg^-1) 32.7 in straw of pearl millet. However, it was at par with treatment (T₃) also recorded the high iron content in stover (32.1 mg kg^-1). Application of T₅ (100% NP + bio- NP consortia @ 6 ml + 30 kg ha^-1 FeSO₄) recorded highest total nitrogen, phosphorus and potassium uptake by grain of pearl millet 59.61, 19.76 and 33.10 kg/ha, respectively followed by T₃ (100% NP + bio-NP consortia @ 4 ml + 30 kg ha^-1 FeSO₄). Similar trend was observed in the stover nutrient content of pearl millet crop i.e., 76.09, 24.02, 96.38 kg/ha, respectively in treatment T₅. Maximum iron uptake by grain and straw of kharif pearl millet i.e., 208.43 g ha^-1 and 221.96 g ha^-1, respectively observed in treatment T₅.
