Summary: Temperature is a critical factor in regulating ecological processes, and the response to temperature changes is particularly important for biogeochemical processes. This review summarizes the negative impact of excessive soil temperature on soil microenvironment, water and nutrient absorption by roots, and maize root-shoot growth. It also proposes potential cultivation strategies to improve maize yield.

Summary: This study investigated the optimal planting and harvesting times for different cassava varieties, as well as the effect of fertilizer on root dry matter yield. Results showed that delaying harvests increased root dry matter yield, but differences between planting dates were marginal. Fertilizer treatments interacted significantly with location, with the largest responses observed at Ido.

Summary: The co-inoculation of Bradyrhizobium with Rhizobium can enhance the growth and grain yield of common beans. The beneficial effect may not only be attributed to biological nitrogen fixation but also to a plant growth-promoting mechanism. Further adjustments are needed to optimize the response under field conditions.

Summary: A study comparing the water requirements of two common bean cultivars aimed at optimizing water use and found that water deficit adversely affected the agronomic performance of both cultivars, while excess water had a greater detrimental effect on one cultivar. The study also revealed a strong correlation between soil cover fraction and grain yield.

Summary: By reviewing the interacting processes determining sink strength and yield potential in wheat, and visualizing them in a set of 'wiring diagrams', the main traits determining sink strength were identified and research gaps were highlighted for achieving gains in sink strength. In the pre-anthesis phase, grain number could be increased through enhanced spike growth and improved fruiting efficiency. In the post-anthesis phase, grain sink strength could be augmented through manipulation of grain size potential and improving spike vascular architecture. The wiring diagrams provide a potential workspace for yield improvement in wheat and other field crops.

Summary: The study shows that the critical period for lentil yield is between 50-126 Cd after flowering, with grain number and biomass being the main factors affecting yield variation, while grain protein concentration follows a bi-linear model.

Summary: The aim of this study was to evaluate the variability in the dry matter accumulation rate of carioca-type common bean grains and determine the success of selection for this trait and the optimal harvest time. Sixteen lines were assessed in three seasons, and a quadratic equation was used to estimate the days needed to achieve maximum dry matter in the grains. Low variability between lines was observed, indicating limited potential for selection based on this trait. The ideal harvest time is when all grains exhibit the characteristic stripes of carioca common beans, which may vary within and between pods of the same plant. Harvesting before complete physiological maturation results in an average daily decrease of 2.75% in grain dry matter.

Summary: This study examined the associations between bean production, Fusarium root rot, and weed in a field plot study. The results showed that variations in bean yield could be partially explained by changes in leaf area, disease incidence, and weed biomass development. These findings contribute to improving field measurement for breeding and mitigation programs.

Summary: In maize, a rational root structure contributes to high grain yield under dense sowing conditions. The study compared the root structure and distribution characteristics of two maize cultivars, DH618 and SC704, under high-yield and high-density planting conditions. The results showed that DH618 had a well-developed root structure and higher root dry weight compared to SC704, leading to higher grain yield.

Summary: The study evaluated the agronomic and qualitative performance of 16 common bean cultivars under irrigation in the autumn-winter season. Results showed that top-dressing N application significantly influenced the agronomic performance of common bean cultivars, with some cultivars exhibiting good response and efficiency in nitrogen use. Additionally, the qualitative performance of common bean grains was also influenced by top-dressing N application, with some cultivars showing improved results in protein content and cooking time reduction.

Summary: This study investigated the nutrient requirements and effects of fertilization on the soil properties and growth status of Erythropalum scandens seedlings through a series of pot experiments. The results revealed that E. scandens seedlings have a stronger sensitivity to nitrogen levels, and excessive fertilization can lead to soil acidification. Proper fertilization treatments can promote better growth status of the seedlings.

Summary: The effect of nitrogen splitting and different irrigation conditions on agronomic and physiological traits of corn was examined. Drought stress resulted in decreased yield, increased proline and abscisic acid contents. The Maxima cultivar exhibited higher resistance to drought stress. Single cross 704 cultivar showed better adaptability to drought stress and nitrogen deficiency.

Summary: The study examined the effects of growth media made of peat and different domestic materials on tomato nutrition, growth, and yield as an alternative to cocopeat in Turkiye. It was found that using vermicompost and its mixtures with peat as growth media resulted in the highest leaf and fruit nutrient concentrations. The highest fruit yields and biomass weights were obtained with solely peat and 1:1 peat + vermicompost medium. Peat-containing growth media, especially peat + vermicompost mixtures, can be used as alternatives to cocopeat in soilless tomato cultivation.

Summary: This study investigated the effectiveness of bacterially solubilized zinc (BSZn) on the early growth of rice plants and the concentration of zinc in the plant parts. The results showed that BSZn can promote seed germination and seedling growth, increase chlorophyll and carotenoid content, and enhance zinc accumulation in the roots of rice seedlings.
