Nutrient Uptake and Quality Parameters of Finger Millet as Influenced by Tillage and Organic Nutrient Management in Finger Millet – French Bean Cropping System

Abstract

A field experiment was conducted at Research Farm of Birsa Agricultural University, Kanke, Ranchi, Jharkhand during 2020-21 and 2021-22. The experimental soil textural class was sandy loam with pH 5.56, EC 0.03 dS/m and OC (5.91 g/kg). The soil was low in available nitrogen (218.63 kg/ha), medium in available phosphorus (15.75 kg/ha) and medium in available potassium (178.32 kg/ha). The experiment was laid out in a split plot design with three replication. The experiment consisted of four main plot treatments viz., conventional tillage–conventional tillage (CT–CT), conventional tillage–zero tillage (CT–ZT), zero tillage–conventional tillage (ZT–CT) and zero tillage–zero tillage (ZT-ZT) and subplot has four treatments with different sources of organic nutrient management viz., 100% N through FYM, 100% N through vermicompost, 50% N through FYM + 50% N through vermicompost and 75% N through FYM + 25% N through vermicompost. The results revealed the significantly highest value of total N uptake (36.02 kg/ha), total P uptake (11.03 kg/ha), total K uptake (51.66 kg/ha), protein content (7.93 %), Ca content (321.34 mg/100 g) and Fe content (4.29 mg/100 g) were observed in conventional tillage-conventional tillage. Among organic sources, 100% N through vermicompost gave maximum value of total N uptake (37.05 kg/ha), total P uptake (11.24 kg/ha), total K uptake (52.25 kg/ha) and protein content (8.07 %).  Ca content (339.15 mg/100 g) and Fe content (4.50 mg/100 g) were observed maximum in 100% N through FYM.
