Significant variation was found in all yield and yield contributing characters of field pea at Madaripur, Gazipur, and Jessore, respectively due to the application of different levels of zinc during 2015-16. Seed yield ranged from 1050-1441 kg ha-1 at Madaripur, 1200-1589 kg ha-1 at Gazipur, and 1105-1487 kg ha-1 at Jessore. The average yield of three locations varied from 1118-1506 kg ha-1. The highest seed yield was recorded from the treatment Zn level 3.0 kg ha-1 which was statistically significant with other treatments, but it was statistically identical to Zn level 2.0 kg ha-1 in Jessore. The stover yield of field pea was showed a similar trend to seed yield. The tallest plant was recorded from the treatment 3.0 kg Zn ha-1 followed by treatment of 2.0 kg Zn ha-1 and the lowest plant height was found in the control treatment. Other characters such as pod length, the number of branches per plant, the number of pods per plant, and the number of seeds per pod showed significant variation due to the application of different levels of Zn. Anonymous (2009) reported that the application of N, P, B, and Rhizobium inoculum was significantly enhanced the positive growth and yield parameters of field pea. Field pea yield contributing characters and yields were influenced significantly due to the application of different levels of boron during 2015-16 at Madaripur, Gazipur, and Jessore. The seed yield ranged from 1104-1371 kg ha-1 at Madaripur, 1198-1560 kg ha-1 at Gazipur, and 1189-1455 kg ha-1 at Jessore, respectively. The average seed yield of three locations ranged from 1164-1462 kg ha-1. The highest seed yield was recorded from the B level of 2.0 kg ha-1 treatment which was significantly higher than the other treatments at Madaripur, Gazipur, and Jessore. The lowest yield was recorded in the control treatment (Table 25). It was observed that the seed yield increased gradually with the increase of B level up to 2.0 kg ha-1. The trend of stover yield showed a similar seed yield. A similar trend was also observed by several authors (Ryan and El-Moneim 2007; Singh et al. 2004). Others yield contributing characters showed variation significantly due to different levels of B application. In most of the cases, the highest performances were found with B level 2.0 kg ha-1 followed by B level of 1.5 and 1.0 kg ha-1 respectively. The interaction effect between Zn and B on the yields of field pea was observed statistically significant during 2015-16 at Madaripur, Gazipur, and Jessore. The highest seed yield was obtained from Zn3.0B2.0 treatment followed by Zn3.0 B1.5 and Zn2.0 B2.0 treatments at Madaripur, Gazipur, and Jessore, respectively, and the lowest yield was recorded from Zn0 B0 in all the locations. The average yield of three locations of field pea varied from 923-1617 kg ha-1 and the average highest % yield increased in Zn3.0 B2.0 (42.9%) treatment followed by Zn3.0 B1.5 (42.1%) treatment over control. Other yields contributing characters such as plant height, pod length, branch per plant, pods per plant, seeds per pod, and 1000 seed weight were significantly influenced due to the combined application of Zn and B but some variations existed at Gazipur and Jessore were plant height was insignificant, pod length, the number of branch per plant and number of seed per pod were nonsignificant at Madaripur. The combined application of Zn and B showed significantly superior yields and yield components of field pea than their single application. Bhuiyan et al. (2008) found that the yield contributing characters of pulses responded significantly due to the combined application of nutrients. Abdo (2001) observed a similar trend with foliar spray of Zn and B. Soil samples were collected from each treated plot for analyzing different soil properties viz. soil pH, organic matter, total N, and available P, K, S, Ca, Mg, Zn and B. Initially the soil pH was 6.6 at Gazipur and 8.2 was at Jessore, but after completion of experiments, the soil pH remained unchanged although minor variation existed. A minor change in soil fertility occurred from the initial status due to different micronutrients management practices. The combined application of Zn and B tended to maintain the initial fertility or increased slightly only OM, and total N, Potassium (K), S, Ca, and Mg slightly decreased in all plots over the initial status. The available Zn and B content of the soil slightly decreased when they were not applied, but remained almost static or increase when applied.
