The external treatment of humic acid and boron has the potential to address these challenges in tomato production. However, the interaction effects of humic acid and boron in tomato cultivation is largely elucidate. This research aimed to evaluate the impacts of humic acid and boron on growth parameters, yield, and quality features of tomato (Lycopersicon esculentum L.). The treatments were consisted of three levels humic acid (0, 50 and 100 ppm) and boron (0, 25 and 50 ppm) and they were foliar sprayed at the vegetative, flowering, and fruit setting stages. The results revealed that combined application of humic acid and boron potentially improved the quantitative and qualitative characteristics of tomato plants over control. The maximum plant height (121.10 cm), the dry weight of each plant (46.72 g), fruit diameter (6.1 cm), single fruit weight (70.4 g), yield per plant (4.45 kg) were observed in combined treatment of 100 ppm humic acid with 25 ppm boron at mature stage. Furthermore, TSS (4.90 °B), total sugar (5.06 mg), vitamin C (21.35 mg), protein (3.11%), ash (0.69 mg), lycopene (4.97 mg), and sodium (6.96 mg) content were higher in 100 ppm humic acid with 25 ppm boron as compared to control at mature stage. These findings revealed that the combined foliar application of humic acid with boron could be practical approach for increasing tomato production and improving quality traits of tomato in subtropical climatic regions.

An experiment was designed to study the impacts of plantlet type (tissue culture and runner) and mulching materials (no mulch, rice straw, sawdust, black polythene, and red polythene) on strawberry cv’s production and quality traits. Festival using a randomized complete block design (RCBD) with three replications. The experimental findings revealed that tissue culture plantlets combined with black polythene mulch produced the highest plant height at the fruiting stage, surpassing the lowest recorded height under runner plantlets without mulch by 80.6%. Similarly, the number of fruits plant-1 increased by 50.4%, single fruit weight by 41.9%, fruit length by 39.3%, and yield plant-1 by 110.7% compared to the least effective combination. For quality traits, this interaction also exhibited the maximum TSS, vitamin C, total phenolic content, and reducing sugars, exceeding the lowest values by 85.1%, 51.5%, 83.8%, and 88.2%, respectively. Results indicated that tissue culture plantlets with black polythene mulch are the most effective approach for strawberry cultivation in Bangladesh and similar agro-climatic regions.

The purpose of this research was to examine the ability of gibberellic acid (GA3) to mitigate salinity stress in tomato plants. The experiment used BARI Hybrid Tomato-5 to investigate the effects of two GA3 dosages (0 and 100 ppm) on plant growth, physiology, and yield parameters in normal and stressed conditions (50, 100, and 150 mM NaCl). Salinity revealed a negative effect on tomato plants in terms of plant height, leaf and branch numbers, flowering and fruiting phases, and physiological features such as photosynthetic pigments, relative leaf water content, electrolyte leakage, proline content, and stomatal conductance including Na+ and K+ ions of plants. The foliar spray of GA3 was useful in enhancing the salt tolerance of tomato plants and stimulated the growth of unstressed plants, resulting in increasing tomato yield.

Water deficiency is acute environmental stress to field crops causing low production of crops. Rice is one of the staple crops whose yields and quality are highly affected due to drought stress. Despite the importance of SA in crop production, little information has been reported concerning the effect of SA under drought stress. Therefore, the possible physiological and morphological responses of rice to SA were investigated under drought conditions. In this study, the external application of 2-hydroxybenzoic acid (Salicylic acid) was identified as a positive tool in decreasing the stress of the drought effect. The field experiment was arranged under a randomized complete block design (RCBD) containing three replications of SA and drought stress treatments. The SA treatments consisted of 0, 250, 500, 750 and 1000 µMm-2 concentrations and drought stresses were slight, moderate and severe. Following the treatments, higher leaf number, leaf area index, relative water content, leaf membrane stability index and pigment content were determined for the application of 750 µMm-2 of SA compared to the alternative treatments and management of plants. Exogenous application of SA during drought stress has growth-promoting and stress priming effects on rice plants, hence reducing yield limitation. The findings of the study imply that SA can be utilized as a protective agent to increase water use efficiency, osmotic management, and pigment content to reduce the negative effects of drought stress on rice growth and physiology, resulting in optimum yield.
