Abstract
A field experiment was conducted to study the âEffect of Biofertilizer and Spacing on Growth of Field Pea (Pisum sativum L.)â during Rabi season 2023-2024 was carried out in a plot which is located nearby Sunshine School of Dirang, West Kameng District of Arunachal Pradesh. The experiment was laid out in a Randomized Block Design (RBD) which have 7 treatments i.e. T0 (control), T1 - B1 + S1(Seaweed + spacing) , T2 - B1 + S2 (Seaweed + spacing), T3-B1 + S3 (Seaweed + spacing), T4- B2 + S1 (rhizobium + spacing), T5- B2 + S2 (rhizobium + spacing), T6- B2 + S3 (rhizobium + spacing) with 3 replication, i.e R1, R2, R3. The Pea variety was WELCOME 2010 was sown for this experiment. Based on the mean performance of the treatment T4- B2 + S1 (rhizobium + spacing) at 25, 50 and 75 DAS was found the best treatment for plant growth. This obtained highest plant height (11.89cm, 36.78cm, 44.67cm), Dry weight (2.75g, 18.42g, 27.43g), Number of Root nodules (11.55, 24.22, 34.89), No. of pods plant-1 (22.33), No. of seeds plant-1 (9.33) and the lowest plant growth was observed in T0 (control). However seed inoculation of Rhizobium and spacing gave the promising results compared to control. This, shows that the seed treatment with biofertilizer (rhizobium) may be the good option for seed growers to achieve higher growth parameters and yield parameters in field pea. Biofertilizer are chosen over chemical fertilizer since they are non-toxic and contain organic elements. The biofertilizers helps to increase growth, yield and quality of fruits in addition to improve soil fertility. Biofertilizer are microorganisms that help plant to grow by increasing the quantity of nutrients.
