Assessment of application of foliar nutrients on yield and quality of field pea (Pisum sativum)

Abstract

A field experiment was conducted at Agronomy Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, and Sardarkrushinagar during rabi season of the year 2017-18 on “Assessment of application of foliar nutrients on yield and quality of field pea (Pisum sativum)”. In all 12 treatment combinations consisting of two levels of inorganic fertilizers viz., 75 % RDF (N1) (15: 30: 00 N: P2O5: K2O kg/ha) and 100 % RDF (N2) (20: 40: 00 N: P2O5: K2O kg/ha) and six foliar sprays at flowering and pod initiation stage viz., Water spray (F1), 1 % Urea (F2), 1 % 19:19:19 N: P2O5: K2O (F3), 1 % Phosphoric acid (F4), 1 % 17:44:00 N: P2O5: K2O (F5), 1 % 00:00:50 N: P2O5: K2O (F6) were tried in FRBD (Factorial Randomized Block Design) with three replications. In all cases, application of 100 % RDF (N2) was found superior than 75 % RDF (N1), application of 100 % RDF (N2) recorded significantly higher grain yield (1423 kg/ha) and straw yield (1915 kg/ha) of field pea. The highest benefit : cost ratio (BCR) value (2.24) and net realization (29640 `/ha) were obtained under 100 % RDF (N2).One per cent foliar spray of 19:19:19 N: P2O5: K2O (F3) at flowering and pod initiation stage recorded significantly the highest grain yield (1650 kg/ha) and straw yield (2228 kg/ha) of field pea. The higher BCR value (2.62) and net realization (38450 ₹/ha) were obtained under 1 % foliar spray of 19:19:19 N: P2O5: K2O (F3) at flowering and pod initiation stage. The interaction effect of different levels of inorganic fertilizers and foliar spray on grain yield/plant (g), grain yield (kg/ha) and straw yield (kg/ha) was found significant. Treatment combination N2F3 (100 % RDF and foliar spray of 1 % 19:19:19 N: P2O5: K2O) produced significantly the highest grain yield/plant (12.93 g/plant), grain yield (1800 kg/ha) and straw yield (2430 kg/ha). The interaction effect of different levels of inorganic fertilizers and foliar spray on rest of the parameters under study was found non-significant.
