An experiment was conducted at Research Area, Pulses Section, CCS Haryana Agricultural University, Hisar, during Rabi 2013-14 to study the influence of chemical and biofertilizers on growth indices, quality and nutrient status in field pea (Pisum sativum L.) under semi arid condition. The experiment was conducted in randomized block design with nine treatments viz., Control, seed inoculation with Rhizobium, Rhizobium+ PSB (Phosphorous solublizing bacteria), Rhizobium + PSB + PGPR (Plant Growth Promoting Rhizobacteria), Recommended dose of fertilizers (RDF), RDF + Rhizobium, RDF +Rhizobium + PSB, RDF + Rhizobium + PSB + PGPR and RDF + ZnSO4@ 25 kg ha-1. The growth indices [(Crop Growth Rate (CGR) and Relative Growth Rate (RGR)] were observed maximum in the combined application of RDF with bio-fertilizers (Rhizobium + PSB + PGPR) as compared to their sole application. Maximum CGR and RGR were recorded at 61-90 days stage compared to 31-60 and 91 DAS- maturity. The significantly highest protein yield was recorded with the combined application of RDF + Rhizobium + PSB + PGPR among all the treatments. Significant lowest protein yield was recorded in control. The RDF + Rhizobium + PSB + PGPR treatment significantly increased available N and P in soil. Various treatments did not produce any significant influence on available potassium. Though the application of RDF + ZnSO4 increased the available zinc in soil but not to significant level. Protein yield (kg/ha) was analyzed, the higher radiation used efficiency (1.22 kg ha-1MJ-1) in the treatment RDF+ Rhizobium+ PSB+ PGPR. The soil temperature were significant influence the absorption of nutrient, the morning time at 5 cm soil depth temperature with range of 16 to 20 degree centigrade which less impact on the flow and absorption of nutrient, the treatment RDF+ Rhizobium+ PSB+ PGPR were efficient higher use of RUE, HUE, HTUE, PTUE and HYTUE higher as followed to rest of the treatment. T max and T min temperature correlation result shows as negative and positive relationship among treatment in the different level.
