Abstract:
The present investigation was conducted at Bajra Research Scheme, College of Agriculture, Dhule. The objective was to estimate the soil properties, yield and quality of pearl millet influenced by integrated nutrient management. The experiment was laid out in Randomized Block Design with eight treatments consists of inorganic fertilizers in combination with organics viz., FYM, vermicompost and poultry manure. Soil chemical properties were estimated at harvest stage. Nutrient uptake and quality parameters were estimated at harvest. Significantly maximum available N, P and K were noted under 50% RDN through fertilizers + 50% N through FYM i.e. 201.79 kg ha^-1, 24.64 kg ha^-1 and 282.16 kg ha^-1, respectively. However, organic C was found higher with the application of 100% RDN through FYM (4.61 g kg^-1). Treatments comprised of vermicompost and poultry manure significantly increases organic C and available N, P and K contents in soil over control. The highest availability of micronutrients viz., Fe, Zn, Mn and Cu (5.97, 0.76, 14.12 and 3.82 mg kg^-1, respectively) were recorded in 50% RDN through fertilizers + 50% N through vermicompost. The maximum N, P and K uptake by grain (53.22, 22.59 and 14.09 kg ha^-1, respectively) and stover (45.17, 28.82 and 156.12 kg ha^-1, respectively) were noticed with application of 50% RDN through fertilizers + 50% N through FYM followed by 100% RDF through inorganic fertilizers. Among the all manure treatments, significantly maximum grain and stover yield (26.51 and 38.05 q ha^-1, respectively) was obtained with the application of 50% RDN through fertilizers + 50% N through FYM. Maximum protein percentage in grain (9.98%) was recorded in 50% RDN through fertilizers + 50% N through FYM, the maximum Fe (48.82 mg kg^-1) and Zn (33.92 mg kg^-1) contents in grain were noticed under the treatment 100% RDN through vermicompost.
