Abstract:
The proper amount of nitrogen, phosphorus and potassium is required to maximize the yield of radish. Thus, the study entitled “Effects of different nitrogen, phosphorus and potassium levels on growth and yield parameters of radish (Raphanus sativus L.) variety Pusa Himani” was conducted to determine the effect of nitrogen, phosphorus and potassium levels on growth and yield parameter in radish from 20^th February to 20^th April 2022 in the field of Rama University, Mandhana, Kanpur, Uttar Pradesh, India. The study was conducted on the Pusa Himani variety of radish. The study was conducted on the Randomized Complete Block Design (RCBD) with three replications and each replication consist of eight treatments i.e. eight different rates of nitrogen phosphorus and potassium. Different rates of fertilizers were: T₁ (0:0:0 NPK kg/ha), T₂ (20:10:15 NPK kg/ha), T₃ (40:20:30 NPK kg/ha), T₄ (60:30:45 NPK kg/ha), T₅ (80:40:60 NPK kg/ha), T₆ (100:50:75 NPK kg/ha), T₇ (120:60:90 NPK kg/ha) and T₈ (140:70:105 NPK kg/ha). Different treatments showed significant effects on all observed parameters. Among various treatments, T₅ recorded the highest germination percentage (94.67%), number of leaves (14.330), shoot length (16.530 cm), shoot weight (0.111 kg), root length (29.270 cm), root diameter (11.133 cm), root weight (0.151 kg), total biomass (0.262 kg), root yield per plot (3.775 kg) and root yield per hectare (37.750 t/ha). Thus it is suggested to use nitrogen (N), phosphorus (P) and potassium (K) at the rate of 80, 40 and 60 kg respectively.
