Seasonal impact on the soil temperature and yield of baby corn (Zea mays L.) under different agronomic practices in tropics of India

Seasonal and diurnal variations in soil temperature play a critical role in baby corn production by influencing nutrient uptake and crop development. This study evaluated the effects of sowing windows, crop geometry and mulching on soil temperature dynamics and yield of baby corn. A field experiment was conducted at Tamil Nadu Agricultural University, Coimbatore, during the winter (January–April) and kharif (June–September) seasons of 2022 using a split-plot design with 3 replications. Results revealed that sowing windows, crop geometry and mulching significantly affected soil temperature at both the surface and sub-surface (15 cm depth) during both seasons. Late sowing (D₃) consistently recorded the highest surface soil temperatures (27.5–29.1 °C at 7:22 hr and 40.1–41.2 °C at 14:22 hr) during winter and kharif, followed by mid (D₂) and early sowing (D₁). Wider spacing (60 × 30 cm) without mulching resulted in higher surface and sub-surface soil temperatures compared to closer spacing and mulched treatments. Sub-surface soil temperature at 15 cm depth was also highest under late sowing and wider spacing without mulching across both seasons. Correlation analysis indicated a significant negative relationship between soil temperature and baby corn yield, with correlation coefficients ranging from -0.57* to -0.98** in winter and -0.60* to -0.94** in kharif 2022. The study demonstrates that appropriate adjustment of sowing time, crop geometry and mulching practices can effectively regulate soil temperature and enhance baby corn productivity under varying seasonal conditions.
Modified micrometeorological influence on growth and yield of baby corn and performance analysis using AquaCrop model

Agronomy Journal, 2026
This study evaluated the effects of sowing dates, spacing, and mulching on baby corn ( Zea mays L.) production and assessed the predictive performance of the AquaCrop model using field trials conducted during winter and kharif 2022 at Tamil Nadu Agricultural University, Coimbatore. Early sowing (January 21 and June 15) combined with closer spacing (60 × 20 cm) and paddy straw mulching enhanced growth attributes, growth rates, intercepted PAR (>56%), radiation use efficiency (>0.50 g MJ −1 ) and physiological parameters (photosynthetic rate: 15.5 µmol CO 2 m − 2 s − 1 ; stomatal conductance: 0.34 mol H 2 O m − 2 s − 1 ; transpiration rate: 3.82 mmol H 2 O m − 2 s − 1 ), resulting in higher total yields despite wider spacing (60 × 30 cm) producing larger cob attributes. The AquaCrop model accurately simulated biomass and yield across planting dates ( R 2 > 0.95). Increased plant density improved leaf area index (3.89 and 4.36 in winter and kharif ), contributing to greater productivity. Overall, AquaCrop serves as an effective decision‐support tool for optimizing baby corn management under varied field conditions.

Bio-mediated synthesis of nanoparticles: A new paradigm for environmental sustainability

Plant Science Today, 2025
The synthesis of nanoscale metals and non-metals is an intriguing subject, and the green synthesis of nanoparticles (NPs) is increasingly utilized across various sectors, including environmental science, agriculture, engineering, and food processing. Traditionally, the production of nanoscale materials relies heavily on physical and chemical processes, which can lead to significant challenges such as high energy consumption and environmental contamination. Poor management of agricultural and industrial waste contributes to greenhouse gas emissions, exacerbates climate change and disrupts ecosystems. Conversely, green nanotechnology offers a safer alternative by leveraging biological materials, that inherently provide capping and reducing agents. This approach is not only more cost-effective but also results in lower pollution levels, thereby enhancing environmental safety. Green synthesis involves the reduction of metallic and non-metallic atoms using plant extracts, microorganisms, and agricultural waste instead of conventional harmful substances. The bioactive compounds, including flavonoids, alkaloids, tannins, and saponins, play a critical role in the bioreduction of metals and the production of nanoparticles. There has been the increasing interest in utilizing these biological sources for green nanoparticle production over the past decade from their potential to serve as economical and environmentally friendly alternatives. Overall, green nanotechnology demonstrates its potential to revolutionize industries and pave the way for a more sustainable and resilient future.

Screening for low Raffinose family oligosaccharides and low Phytic acid lines in macro mutant Urdbean (Vigna mungo L. Hepper)

Vegetos, 2014
Oligosaccharides are important component of urdbean in terms of metabolizable energy for monogastric animals and human. Sucrose, raffinose, stachyose and verbasecose are the four main oligosaccharides present in urdbean. Out of the four, only sucrose is nutritionally useful. When raffinose stachyose and verbascose are fermented by microbes present in the gut, the results are flatulence and discomfort, which ultimately lead to poor weight gain. The objectives of this work were to establish to identify low raffinose family oligosaccharide (RFO) and Low phytic acid (LPA) in macro mutants of TNAUCo (Bg) 6. The seeds of TNAUCo (Bg) 6 were treated with gamma rays (200Gy and 250Gy) EMS (15mM and 20mM). The frequency and spectrum of macro mutants different dose/concentration, number of chlorophyll mutants and Macro mutants observed. Chlorophyll mutants and viable mutants calculated based on the biological damage. The spectrum of chlorophyll mutants (Chlorina, Xantha, Albino and Viridis) and viable mutants (Tall and erect, dwarf, spreading, compact and bushy, crinkled and leathery, small leaf, big and broad leaf, narrow leaf, sterile, non flowering, pod and seed mutants) were observed in both generation. The spectrum of chlorophyll mutants increased with the decreased in dose of mutagen and increased with lower concentration. Total of 22 and 102 macro mutants were isolated from gamma ray and EMS treatments. Compare to all treatment 15mM of EMS treatments were establish more efficient in causing less biological injure and inducing highest amount of mutations. The total of 124 macro mutant three Low Verbascose mutant M2-F58 (0.06 mg/g), M2-F117 (0.13 mg/g) of 15mM, M2-F27 of 20mM (0.13 mg/g) and one low Phytate mutant in M2 -F37 of 15mM EMS (0.02 mg/g) were selected.
