dc.description.abstractA Field experiment was conducted in Rabi season 2019 at Instructional farm, College of Agriculture Kota, Rajasthan using Kota Masoor-3 variety of lentil as a test crop to studies on effect of phosphorus, zinc and their liquid bio fertilizers on soil fertility and productivity of lentil. The experiment was laid out in randomized block design with 10 treatments viz. T1 - Absolute control, T2 - Recommended phosphorus dose (40 kg ha-1), T3 - ZnSO4 25 kg ha-1 soil application, T4 - Biophos @ 5 ml kg-1, T5 - Biozinc @ 5 ml kg-1, T6 - Biophos @ 5 ml kg-1+ Biozinc @ 5 ml kg-1, T7 - 50% RD phosphorus + Biophos @ 5ml kg-1, T8 - 12.50 kg ZnSO4 + Biophos @ 5ml kg-1, T9 - 50% RD phosphorus + Biophos @ 5ml kg-1+ Biozinc @ 5ml kg-1, T10 - 50% RD phosphorus + 12.5 kg ZnSO4 + Biophos @ 5 ml kg-1+ Biozinc @ 5 ml kg-1. Among all treatment application of T10 - 50% RD phosphorus + 12.5 kg ZnSO4 + Biophos @ 5 ml kg-1+ Biozinc @ 5 ml kg-1 significantly increased the growth and yield attributing characters of lentil viz., plant height (25.97 cm), number of nodules (30.62), fresh weight of nodules (37.04 mg plant-1), dry weight of nodules (6.61 mg plant-1) and protein content in seed (20.59 %), chlorophyll content (3.05 mg g-1), number of pods plant-1 (199.11), grain yield (2337 kg ha-1), straw yield (4630 kg ha-1) and biological yield (6967 kg ha-1). It also attained significantly higher nutrient content and uptake in grain, N (3.29 %, 76.92 kg ha-1), P (0.93 %, 21.75 kg ha-1), K (1.13 %, 26.51 kg ha-1), Zn (32.97 mg kg-1, 770.91 g ha-1) and in straw, N (1.24 %, 56.94 kg ha-1), P (0.31 %, 15.20 kg ha-1), K (1.53 %, 75.12 kg ha-1), Zn (29.97 mg kg-1, 1474.98 g ha-1) was found in T10 - 50% RD phosphorus + 12.5 kg ZnSO4 + Biophos @ 5 ml kg-1+ Biozinc @ 5 ml kg-1. Application of 50% RD phosphorus + 12.5 kg ZnSO4 + Biophos @ 5 ml kg-1+ Biozinc @ 5 ml kg-1 recorded the maximum increment in available nitrogen (289.87 kg ha-1) and in available potassium (259.31 kg ha-1) while, in case of available phosphorous content (24.35 kg ha-1) and available Zinc (0.76 mg kg-1) recorded the significant increase in the application of Recommended phosphorus dose 40 kg ha-1 and application of ZnSO4 25 kg ha-1 in soil, respectively as compared to other treatments and fetched highest net returns (88867 Rs. ha-1) with the highest B: C ratio (3.81).en_US
