Abstract:
A field experiment was conducted at Research Farm, Department of Soil Science and Agriculture Chemistry, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif season 2014-2015. The soil of experimental field was clayey in texture, moderately high in available nitrogen, moderate in available phosphorus, rich in available potassium with slightly alkaline in reaction. Five treatments with various combinations of fertilizer were compared with each other in Randomized Block Design with four replications. The treatments were- 1) NF (no fertilizer)), 2) RDF (recommended dose of fertilizer, 60:30:00 kg ha-1), 3) RDF+15k2O (60:30:00 + 15 kg K2O ha-1), 4) RDF+30k2O (60:30:00 + 30 kg K2O ha-1), 5) RDF+45k2O (60:30:00 + 45 kg K2O ha-1). Treatments were compared to evaluate the effect of different fertilizer levels on growth, yield and economics of pearl millet. Experiment results revealed that fertilizer treatments significantly influenced the growth and yield of pearl millet.
Maximum grain yield (16.90 kg ha-1) was recorded with RDF+45k2O. The second best treatment in this regard was RDF+30k2O with grain yield of 16.60 kg ha-1. Maximum potassium use efficiency (12.63 kg kg-1) was recorded with RDF+30k2O. The second best treatment in this regard was RDF+45k2O with grain yield of 9.08 kg kg-1. Both of these treatments were statistically similar with each other.
In nutshell it can be inferred that the treatments which received the fertilizer at the rate of 60:30:45 NPK kg ha-1 and 60:30:30 NPK kg ha-1, both being at par with each other, improved the soil fertility status and profitability of the pearl millet crop.
