Effect of Golden Dock (Rumex maritimus) Residues on Weed Growth Performance of Boro Rice (cv. BRRI dhan58 and BRRI dhan74)
Get PDFAllelopathy plays an important role in weed control and crop productivity. We evaluated the effect of the residues of Rumex maritimus on the growth performance of boro rice comprising two cultivars i.e., BRRI dhan58 and BRRI dhan74 and four rates of R. maritimus residues treatment such as 0, 1.0, 2.0, 3.0 t/ha and a farmers practice. The experiment was laid out in a randomized complete block design (RCBD) with three replications. We identified four weed species (Panikachu, Shama, Shusni, Chesra) belonging to four families. Dry weight of Shama, Shusni, Chesra except Panikachu were significantly affected by variety. The highest Shama dry weight (6.61 g/0.0625 m2) was found in BRRI dhan74 and the lowest weed population (5.81 g/0.0625 m2) was obtained in BRRI dhan58 at 1% level of probability and also the highest Chesra dry weight (5.58 g/0.0625 m2) was found in BRRI dhan74 and the lowest weed population (4.89g/0.0625 m2) was obtained in BRRI dhan58 at 1% level of probability. The highest Shusni dry weight (5.11 g/0.0625 m2) was found in BRRI dhan58 and the lowest weed population (5.00 g/0.0625 m2) was obtained in BRRI dhan74 at a 1% level of probability. Weed density and dry weight were also significantly affected by variety and residue treatment. Results of this study indicate that R. maritimus residues showed the potential to inhibit weed growth of boro rice. Therefore, R. maritimus residues might be used as an alternative way for weed management in effective and sustainable crop production

Get PDFThe sustainable management of water resources is essential for agricultural productivity, especially in areas with scarce water availability. This study focused on assessing groundwater quality for irrigation near the subsurface dam area of Miyako Island, Japan. Water samples from three observation points were tested for various parameters, including electrical conductivity (EC), sodium adsorption ratio (SAR), soluble sodium percentage (SSP), residual sodium bicarbonate (RSBC), permeability index (PI), Kelley\u27s ratio (KR), and magnesium adsorption ratio (MAR). EC values ranged from 270 to 800 µS/cm, suggesting water quality ranging from doubtful to good. SAR values between 0.23 and 1.49 suggested excellent quality. SSP ranged from 7.90% to 31.71%, mostly indicating good to excellent quality. RSBC values fluctuated between -1.57 to 1.45 epm, largely within safe limits. PI values varied from 40.34 to 75.83, indicating good permeability. Total hardness (TH) ranged from 105.50 to 326.45 ppm, classifying the water as hard to very hard. MAR values were below 50, suggesting potential soil issues. A numerical model confirmed observed Ca²⁺ concentrations, showing an increasing trend due to enhanced CO₂ emissions and lower pH. The data analysis revealed strong positive relationships between SSP and KR (r = 0.984), SAR and SSP (r = 0.951), and SAR and KR (r = 0.960). Despite generally acceptable values, continuous monitoring is recommended, especially for hardness, to ensure sustainable crop production. This study underscores the need for regular assessment and management of groundwater quality in subsurface dam areas to mitigate potential adverse effects on soil and agricultural productivity

A Review on Impact of Different Nitrogen Management Techniques on Maize (Zea mays L.) Crop Performance
Get PDFNitrogen (N), as a primary nutrient requirement of maize (Zea mays L.), plays a critical role in its development and productivity. Proper nitrogen management practices involve a delicate balance between providing an adequate amount of this nutrient and mitigating potential environmental impacts. When implemented effectively, these practices can significantly improve corn production. An adequate nitrogen supply promotes vigorous vegetative growth, contributing to strong stalks and an abundance of leaves, which are essential for maximizing the plant\u27s photosynthetic capacity. This lush foliage, in turn, leads to increased photosynthesis and carbohydrate production, providing the energy maize needs throughout the reproductive stage to develop and fill its kernels. In addition, nitrogen is closely linked to kernel development. Well-timed and dosed nitrogen applications can result in larger, well-filled ears with plump kernels, ultimately increasing both the quantity and quality of the maize yield. Environmental considerations, such as reducing nitrogen runoff and greenhouse gas emissions, are important for maintaining ecosystems and mitigating climate change. Thus, this review article highlights the need for a holistic approach to nitrogen management, combining innovative techniques with sustainable agricultural practices, to ensure food security and environmental conservation in maize production systems
