    Response of new genotype pea (Pisum sativum L. var. hortense) to varying seed rates and fertility levels
    (Palampur, 2022-11-17) Kanaiyalal, Patel Swapnil; Rana, M. C.
    This investigation was carried out at CSK HPKV, Palampur during rabi season of 2021- 22. Twelve treatments combination of three seed rates (60, 75 and 90 kg/ha) and four fertilizer levels [control, 50% NPK, 100% NPK (50:60:60 kg/ha NPK) and 150% NPK] were evaluated for growth, development, productivity, soil properties and profitability of a new genotype/line of garden pea. Soil of experimental field was silty-clay loam in texture and acidic in reaction. The soil was high in available nitrogen, medium in potassium and phosphorus. Significantly highest plant population/m2 , plant height and dry matter accumulation/m2 were observed with seed rate of 90 kg/ha. However, dry matter accumulation/plant was found to be significantly highest with seed rate of 60 kg/ha. The developmental parameters were not significantly affected by seed rates. Green pod yield, seed yield, haulm yield, straw yield and biological yield, all were significantly highest with seed rate of 90 kg/ha. N, P and K content in seed and straw was highest with seed rate of 60 kg/ha. However, with 90 kg/ha of seed rate had significantly higher N, P and K uptake which was at par with 75 kg/ha. Partial factor productivity, agronomic efficiency, NPK apparent recovery, all were increased with increasing seed rate from 60 to 90 kg/ha. Net returns and B: C were significantly higher with 90 kg/ha of seed rate which was at par with 75 kg/ha. Total output, input and net energy (MJ/ha) was significantly highest with seed rate of 90 kg/ha. Whereas, energy productivity (kg/MJ) and energy intensity in economic term (MJ/rupee) was significantly higher with 90 kg/ha of seed rate which was at par with 75 kg/ha. Amongst fertility levels, 150% NPK had significantly highest plant height, dry matter accumulation/plant and dry matter accumulation/m2 . However, number of nodules/plant was highest in 50% NPK. Days taken to 50% flowering, pod initiation, first picking, last picking and maturity of garden peas were significantly higher in the treatment where 150% NPK was applied which was at par with 100% NPK. The significantly higher green pod yield, seed yield, haulm yield, straw yield and biological yield, all were recorded with 150% NPK which was at par with 100% NPK. Significantly higher N, P and K uptake was observed with 150% NPK which was at par with RDF. Partial factor productivity, agronomic efficiency, NPK apparent recovery and physiological efficiency, all were decreased with increasing fertility level from 50% to 150% NPK. 150% NPK had significantly higher net returns and B: C ratio which were found to be at par with RDF. Total input and output energy were significantly highest with 150% NPK among fertility levels while net energy and energy intensity in economic terms was significantly higher with 150% NPK which was at par with RDF. Significantly highest energy productivity was obtained in control and lowest was recorded with 150% NPK.
