“…Variation in the number of pods per plant, dry matter accumulation and growth rate due to different treatments might be attributed as positive assotiation with leaf area, number of leaves per plant and net assimilation rate of soybean plants (Malek et al, 2012). The differences in total dry matter accumulation in genotypes reflect differences in photosynthetic production (Bhattacharya, 2021).…”

Background: In India, the area under soybean is steadily increasing, while production and productivity is low compared to the world average. To bridge this gap, factors of production determining the per-unit production plays a crucial role. In order to identify and quantify the factors of soybean production and their contribution, present study was undertaken. Methods: The field experiments were conducted during kharif 2019 and 2020 in randomized block design with seven crop management practices for evaluation of effect of individual practice on soybean yield. Result: Soybean grown with full practice (3221 kg ha-1) gave significantly higher seed yield over omission of RDF (2489 kg ha-1) and weed management (2560 kg ha-1). Increase in seed yield with full practice over omission of RDF was 22.72% and over omission of weed management was 20.52%. The yield gap was higher with omission of RDF (732 kg ha-1) and omission of weed management (661 kg ha-1). Economic gain due to full practice was maximum over the omission of the practice. Least break-even cost was incurred with full practice (₹12.93 kg-1), while higher with omission of weed management (₹14.81 kg-1). Crop output efficiency in terms of partial factor productivity and agronomic efficiency was higher with full practice.

“…Light availability, light collection, energy conversion, and the shape of the plant canopy are the factors that influence yield potential. Energy conversion, which is dictated by photosynthetic efficiency, is a major limiting factor affecting carbohydrate partitioning crops including rice, wheat, and maize, as well as cowpeas, that contributes to yields below their potential maximum [4,5]. Because photorespiration might lose up to 50% of fixed carbon under some conditions, Carbondioxide (CO 2 ) enrichment experiment has continuously provided compelling evidence towards enhanced yields.…”

Recent studies have found compelling evidence that enhancing photosynthetic mechanisms through genetic engineering can increase crop yield potential. This paper focuses on cowpea productivity in Sub-Saharan Africa, its importance, factors limiting photosynthetic potential, and techniques towards boosting cowpea photosynthetic efficiency. High light intensity, low temperature, low CO2 environment, and water scarcity have all been identified as key limiting factors for crop photosynthetic efficiency. Deactivation of Rubisco functioning in shade has also been noted to reduce cowpea photosynthetic potential. However, recent successes have been observed through genetic manipulation of photosynthesis traits so as to improve photosynthetic efficiency and yield under control conditions with considerable increase in yield from 14 to 40%. Thus, improving photosynthesis has the potential to increase crop productivity.

“…The dry-matter production of different crop species is influenced by the crop growth stage and photosynthetic variations (Raza et al, 2020). The DMA is a complex process, under a strong influence of the environment, cultivar and their interaction (Bhattacharya, 2021;Lammerts et al, 2017;Pszczółkowski et al, 2021). Characterizing the ecophysiological factors responsible for DMA is essential for understanding the high-yielding conditions for Siberian wildrye.…”

Siberian wildrye (Elymus sibiricus L.) is a perennial and self-fertilizing forage grass that support animal husbandry and environmental sustenance in the world. In order to explore influence of nitrogen(N) application in Siberian wildrye seed production, the field experiments were conducted to evaluated the effect of different N treatments (of 0, 30, 60, 90 and 120 kg/hm2) on dry matter, N accumulation, transport and utilization, yield components and seed yield of Siberian wildrye DJ-01, which was generated and stored in our lab. The results showed that the 90 kg/hm2 group significantly improved Fertile tillers m−2, spikelets per fertile tiller, 1000-grain weight and seed yield. Furthermore, the seed yield of 90 kg/hm2 group reached 899.3 kg/hm2 and elevated 45.6% compared with 0(CK) group. Moreover, we found that Siberian wildrye exhibited more advantages in dry matter and N translocation. The increment of grain N depended on pre-anthesis dry matter translocation (Pre-DMT) and pre-anthesis N translocation (Pre-NT), but not post-anthesis dry matter accumulation (Post-DMA) and post-anthesis N uptake (Post-NU) to seed yield. With the increase of N, N partial productivity and N absorption efficiency gradually decreased. All data showed the 90 kg/hm2 had the best effects on seed yield components, seed yield, dry matter accumulation (DMA), N accumulation and N efficiency. These results provide an ideal strategy to expand the plant area of Siberian wildrye.
