“…The highest number of pods plant -1 (88.42) was recorded with application of 60 kg P ha -1 which was significantly different from other treatments ( Table 1). The results are in agreement with the findings of Khanam et al (2016) who reported that the number of pods plant -1 increased with the increase of phosphorus rate up to a certain limit and then decreased. Different levels of boron fertilizers also significantly influenced the number of pods plant -1 .…”

“…The highest soybean yield (1.66 t ha -1 ) was produced when the crop was fertilized with 60 kg P ha -1 and the lowest (1.26 t ha -1 ) in control treatment (Table 1). The result was supported by the findings of Khanam et al (2016). Seed yield of soybean varied significantly with different levels of B fertilizer application ( Table 2).…”

“…Since P and B has significant positive impact on biological nitrogen fixation, the plant might have had harvested more N through biological nitrogen fixation. In addition, nutrients maintain stoichiometry in building cells and organs and therefore, application of a deficient nutrient (as P and B in our case) could have improved uptake and assimilation of other nutrients resulting a significant improvement of yield (Hawkesford et al, 2011;Khanam et al, 2016;Sentimenla et al, 2012).…”

The field experiment was conducted at Agronomy Field of Patuakhali Science and Technology University, Patuakhali during the period from December 2019 to May 2020 to evaluate the effect of phosphorus (P0 = 0 kg P ha-1, P1 = 30 kg P ha-1, P2 = 60 kg P ha-1, P3 = 90 kg P ha-1) and boron (B0 = 0 kg B ha-1, B1 = 4 kg B ha-1, B2 = 6 kg B ha-1) and their combinations on nodulation and yield attributes of soybean. Number of nodules plant-1, number of pods plant-1, number of seeds pod, 1000-seed weight, seed yield, stover yield, biological yield and harvest index increased significantly up to 60 kg P ha-1. On the other hand, number of nodules plant-1, number pods plants-1, number of seeds pod-1, 1000-seed weight, seed yield, stover yield, biological yield and harvest index of soybean were enhanced significantly up to 4 kg B ha-1. The combination of 60 kg P ha-1 and 4 kg B ha-1 depicted the highest number of nodules (177.8), plant height (75.60 cm), number of pods plant-1 (92.72), number of seeds pod-1 (2.92), weight of 1000-seed (155.3 g) seed yield (1.91 t ha-1), stover yield (2.98 t ha-1), biological yield (4.89 t ha-1) and harvest index (39.06%). Thus, the combined application of 60 kg P ha-1 and 4 kg B ha-1 could be the optimum for getting maximum yield of soybean. Bangladesh Agron. J. 2020, 23(2): 127-133

SummaryThe common bean (Phaseolus vulgaris L.) has been the subject of a number of studies and has been described by many authors as a legume with low nitrogen fixing potential compared to other legume species. The first objective of this study is to assess the development and growth of P. vulgaris L. var. Djedida and its yield at different developmental stages (vegetative, flowering and fruiting), in the presence and absence of nitrogen fertilizer (Urea 46) in an arid climate and in a soil containing high level of CaCO3 and assimilable phosphorus. The second objective is to carry out a survey on nodulation, number of spores and mycorrhizal infection under these conditions. The results showed that the nitrogen fertilizer amendment is mainly significant (p< 0.0001) for various morphological parameters. Indeed, great improvement was observed on the majority of the morphological parameters with considerable percentages. However, no significant effect was reported for the roots length. In addition, a negligible number of nodules were obtained in the plot without fertilization and no significant effect on the number of spores was recorded. Furthermore, the effect of fertilization on the arbuscular intensity (a%, A%) and on mycorrhizal colonization (M%, m%) of the roots was found to be significant. The soil in the arid region of Biskra showed significant mycorrhizogenic potential, although the conditions in this region were not very favorable for their development, which could constitute an effective biological resource to improve the tolerance of host plants to biotic and abiotic constraints.

“…However, the world average yield of soybean was about 2.9 t ha -1 (FAOSTAT, 2018). The reason for low yield rate of soybean is mainly due to use of low yielding varieties and insufficient agronomic management (Khanam et al, 2016). Experimental evidences reveal that soybean is highly responsive to different fertilizers and its yield can be increased remarkably through the judicious fertilization (BARI, 1988;Mohamed, 1984;Kazi et al, 2002).…”

A field experiment was conducted during the period from January to May 2014 to study the response of growth, flower dropping, pod setting and yield of two soybean varieties to foliar fertilization of urea at early stage of flowering. Soybean varieties, BARI Soybean-5 and BARI Soybean-6, were feeded with four supplemental foliar spray treatments of fertilizer, viz. M1: Control i.e., no additional nutrient spray; M2: 20% of recommended urea spray at flowering; M3: 20% dose of the recommended MoP; and M4: 20% dose of the recommended DAP at early flowering stage. The experiment was laid out in a split-plot design with three replications. There was no significant effect of variety, fertilization spray or their interaction observed on growth parameters. However, flower and pod dropping was affected with higher flower dropping (55.2%) in BARI Soybean-5 and maximum pod dropping (16.44%) with DAP spray treatment. Higher yield attributes’ values such as seeds pod-1 (2.42), seed yield (1.18 t ha-1), stover yield (1.02 t ha-1), and biological yield (2.21 t ha-1) were obtained with foliar DAP spray treatment. The interaction of BARI Soybean-5 and foliar DAP spray showed the highest seed yield (1.48 t ha-1), stover yield (1.26 t ha-1) and biological yield (2.75 t ha-1). Bangladesh Agron.
