 ABSTRACT

The field experiment was conducted in field at Regional Research Center, Amravati during kharif season in 2018-19. The experiment was laid out in Randomized block design with three replications consisting of seven treatments. Based on inputs nutrient application rate 25:32:32 kg/ha N:P2O5:K2O comprising of T1: SSNM basal recommendation through nutrient expert (35:49:43 NPK kg/ha), T2: T1 – N Omission (00:32:32 NPK kg/ha), T3: T1 – P Omission   (25:00:32 NPK kg/ha), T4: T1 – K Omission (25:32:00 NPK kg/ha), T5: RDF (NPKS) (30:75:30:20 NPK S kg/ha), T6: Farmers practice (23:58:00 NPK kg/ha), T7: Absolute control. The observation on Yield attributes viz., pods per plant, seed index, seed yield kg/ha, straw yield kg/ha and harvest index was recorded at the time of harvesting.  Significantly highest no. of pods per plant (19.00) was recorded with application NPK. The mean of test weight was (10.73 g) found to be highest with the ample application of NPKS. The significantly highest seed yield (1718 kg ha-1) was recorded with application of NPKS followed by omission of K (1517 kg ha-1) while lowest seed yield (1115 kg ha-1) was recorded under absolute control and omission of Phosphorus (1296 kg ha-1). The mean straw yield recorded was significantly highest (2111 kg ha-1) under combined application of NPKS whereas lowest straw yield (1443 kg ha-1) was registered in treatment absolute control. The treatment with RDF (NPKS) recorded higher net returns and higher B: C ratio.
