Crop Geometry and Intercropping of Legume and Oilseed in Irrigated Pearlmillet K. Nagarajan, S. Sanbagavalli, C. Jayanthi, Ga. Dheebakaran, A. Senthil Indian Journal of Agricultural Research, 2025 Background: Pearlmillet is conventionally cultivated by farmers either broadcasting or uniform row spacing of 45 cm where it is difficult to accommodate an intercrop. Modified planting pattern provides additional space for intercrop component as well as harvest better solar energy in the system. Methods: The field experiment was conducted in Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during Kharif (July-October) of 2019. The experiment was laid out in split plot design and were replicated thrice. Different crop geometry viz. 45 x 15 cm, 60 x 15 cm, 30/60 x 15 cm and 30/90 x 15 cm were adopted in main plots, whereas intercropping [S1- Greengram, S2-Sesame and S3- No intercrop] were allotted in subplots. Result: Pearlmillet grown under paired row sowing 30/90 x 15 cm recorded higher growth attributes and yield parameters. Grain and stover yields was also recorded higher in the above-mentioned crop geometry. In intercropping system higher growth and yield parameters was observed in sole crop treatment and it was on par with greengram intercropping system. Pearlmillet grown under paired row sowing 30/90 x 15 cm (M4) + greengram (S1) recorded higher equivalent yield.
Harnessing green synthesized zinc oxide nanoparticles for enhancement of sweet corn yield and quality S Sarin, S Sanbagavalli, P Janaki, P Geetha, S K Rajkishore Plant Science Today, 2025 Sweet corn (Zea mays var. saccharata), cherished globally for its sweet taste and nutritional richness, is sensitive to zinc availability-a key micronutrient vital for enzymatic activity, photosynthesis and kernel development. Despite its importance, zinc deficiency in agricultural soils remains a significant barrier to enhancing crop yield and nutritional quality. This study explores the efficacy of foliar-applied green-synthesized zinc oxide nanoparticles (ZnO NPs) using Moringa oleifera leaf extract in enhancing sweet corn yield and quality under field conditions at Tamil Nadu Agricultural University, Coimbatore, during the Kharif season of 2024, employing a Randomized Block Design with seven treatments, varying ZnO NP concentrations from 100 to 600 ppm, applied at 40 and 60 days after sowing (DAS). The findings revealed that foliar application of ZnO NPs at 500 ppm significantly enhanced yield parameters, including cob weight (269.9 g), grain yield (10277 kg/ha), green cob yield (16195 kg/ha) and green fodder yield (16393 kg/ha) along with quality attributes such as total soluble solids (16.33 ºBrix), total sugars (12.07 %) and carbohydrate content (25.08 %). Enhanced zinc uptake (357.5 g/ha) and recovery efficiency (50.63 %) were also recorded. Correlation analysis also revealed strong positive associations between yield traits, such as cob weight, grain yield and green fodder yield, with zinc uptake and content in grains. These results underscore the potential of ZnO NPs in optimizing zinc bioavailability to bolster sweet corn yield and nutritional value and thereby positioning ZnO NPs as a promising and sustainable biofortification strategy.
Effect of Organic Nutrient Management Practices on Growth and Yield of Short-duration Cassava (Manihot esculenta Crantz) S. Ashokh Aravind, E. Somasundaram, S. Sanbagavalli, P.S. Kavitha, S.R. Venkatachalam, R. Sunitha Indian Journal of Agricultural Research, 2025 Background: Cassava is an important tropical tuber crop with great potential, particularly for short-duration varieties. Understanding the impact of nutrient management practices on the growth and yield of cassava is crucial for improving its productivity. Methods: Field experiments were conducted at Tapioca and Castor Research Station, Yethapur, Salem in 2022-2023 to determine the effect of various nutrient management practices on the growth attributes, biomass production, dry matter distribution and yield characteristics of short-duration cassava. The experiment was laid out in a randomized block design with twelve treatments and three replications. Results: The integrated nutrient management practice of FYM @ 25 t ha-1 + 100% RDF + cassava booster spray (T10) resulted in higher crop growth, dry matter production, yield attributes, tuber yield and top yield. This was comparable with the organic practice of Wood ash @ 2 t ha-1 + 3% panchagavya foliar spray (T7) among other organic practices. The control treatment with no manures, fertilizers or foliar sprays recorded lower growth and yield. The positive correlation between growth and yield attributes and yield was also observed. In conclusion, the application of FYM @ 25 t ha-1 + 100% RDF + cassava booster spray and Wood ash @ 2 t ha-1 + 3% panchagavya foliar spray were effective in improving the growth and yield of short-duration cassava. From the study, it is also evident that the short-duration cassava is suitable for organic cultivation and can be integrated into existing cropping systems.
Perspectives on nutrient management through different farming practices for sugarcane production S Mathesh, S Sanbagavalli, P Geetha, P Janaki, M Gnanchitra, N Sritharan Plant Science Today, 2025 India ranks second among the world’s leading producers of sugarcane and in recent decades, input usage has more than doubled to meet the growing global demand for bioenergy. This surge has contributed to climate change mitigation and reduced dependence on fossil fuels. However, the long-term sustainability of sugarcane production is increasingly uncertain due to the adverse environmental impacts of intensive input use and non-optimized production methods. As the crop's potential for ethanol and green energy gains prominence, it is imperative to simultaneously enhance environmental performance. Nutrient depletion in plant crops often results in yield decline in subsequent ratoons, leading to reduced productivity and economic viability. Sustainable sugarcane production can be achieved by adopting natural and organic farming systems that promote resource conservation and minimize ecological damage. Organic nutrient management offers a viable alternative to maintain soil fertility, reduce input dependency and improve produce quality by avoiding harmful residues. In this context, the adoption of optimal nutrient management practices through natural and organic system has emerged as a research priority for ensuring long-term sustainability. Organic farming systems have attracted increased interest and can address some of the problems faced by humans as well as the agriculture sector. These systems not only contribute to environmental protection and the conservation of non-renewable resources but also address concerns related to food quality, ecosystem balance and farm profitability.
Nano seed priming with biogenic ZnO: Assessing the germination potential of sweet corn seeds S Sarin, S Sanbagavalli, V Manonmani, S K Rajkishore, Sathya Moorthy Pon, S Marimuthu, G Gowtham Plant Science Today, 2025 Sweet corn (Zea mays var. saccharata) is a widely cultivated crop valued for its high sugar content and nutritional profile. Seed priming is a pre-sowing technique that enhances germination and seedling vigour and nanopriming has gained prominence with the advent of nanotechnology (NPs). This study aimed to standardize the green synthesis protocol for zinc oxide nanoparticles (ZnO NPs) using Moringa oleifera (MO) leaf extract and assess their impact on sweet corn seed priming. ZnO NPs were synthesized by co-precipitation method, characterized via XRD, FTIR, UV-Vis, TEM and EDAX analyses and subsequently applied in seed priming treatments at concentrations ranging from 100–500 ppm. The laboratory experiment, conducted in a Completely Randomized Design (CRD), evaluated germination parameters such as Germination Percentage (GP), Germination Rate (GR), Seedling Vigour Index (SVI), Mean Germination Time (MGT) and Coefficient of Velocity of Germination (CVG). Results revealed that ZnO NP priming significantly improved germination performance, with the 100 ppm as an ideal priming treatment exhibiting improvement in germination percentage (89.33 %), seedling length and vigour index (3873). The study suggests the potential of biogenically synthesized ZnO NPs in enhancing seed germination and seedling vigour, demonstrating their applicability as an eco-friendly priming agent These findings not only demonstrate the potential of green-synthesized ZnO NPs as an eco-friendly priming agent but also underscore their broader applicability in advancing sustainable agriculture through enhanced crop establishment and resource-efficient seed treatments.
Impact of Organic Nutrient Management Practices on Growth Dynamics and Economics of Short-duration Cassava (Manihot esculenta Crantz.) S. Ashokh Aravind, E. Somasundaram, S. Sanbagavalli, P.S. Kavitha, S.R. Venkatachalam, R. Sunitha Agricultural Science Digest, 2024 Background: A series of field experiments were conducted at the Tapioca and Castor Research Station (TCRS), Tamil Nadu Agricultural University, Yethapur, Salem from 2022 to 2023. The purpose was to investigate the growth dynamics and economics of short-duration cassava under different nutrient management practices including both integrated and organic approaches. Methods: Twelve treatments were carried out consisting of various combinations of organic manures, liquid organic foliar sprays, integrated nutrient management treatments and a control treatment (no manures/fertilizers/sprays). The experiments were carried out in a randomized block design (RBD) with three replications at the same location. Results: The results revealed that the different nutrient management practices had a significant impact on the physiological response throughout the various stages of plant growth. Based on the average data from two experiments, the INM treatment (FYM @ 25 t ha-1 + 100% recommended dose of fertilizers and cassava booster spray) showed the highest physiological response during the final phase of growth. This treatment showed superior performance in terms of leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), net assimilation rate (NAR), tuber bulking rate (TBR) and mean TBR. The organic treatment (wood ash @ 2 t ha-1 and 3% panchagavya foliar spray) recorded comparable performance to the INM treatment in major parameters such as LAI, CGR, RGR and NAR. However, it followed the INM treatment in terms of mean TBR. Economic analysis revealed that the INM treatment yielded the highest net income and benefit-cost ratio (BCR), followed by the organic treatment. The control resulted in the least returns. In conclusion, the findings highlight the effectiveness of the INM treatment and the promising performance of the organic treatment which can contribute to sustainable and profitable cassava cultivation.
Impact of moisture deficit stress at critical growth stages on growth and yield of hybrid maize N Reemala, S Sanbagavalli, A P Sivamurugan, K Vanitha, V V N Kumari Plant Science Today, 2024 A field experiment was conducted in field no. 37F of Eastern Block Farm at Tamil Nadu Agricultural University, Coimbatore, India, during the summer season (January-May) of 2024 to assess the impact of moisture deficit stress at critical growth stages (knee high stage, tasselling, and grain filling stages) on growth and yield of hybrid maize. The growth parameters like plant height and dry matter production were significantly affected by moisture deficit stress. Significant decrease in the yield attributes such as cob length (cm), cob weight (g), number of grains per cob, 100-grain weight, shelling percentage (%), grain yield (kg/ha), and stover yield (kg/ha) was observed. Moisture deficit stress at the vegetative stage significantly reduced plant height and leaf area index. Studies revealed that grain yield and dry matter are significantly reduced in the reproductive stage (T4) and grain filling stage (T6) compared to control plants provided with irrigation at all critical growth stages (T7). The yield reduction was found to be higher at moisture stress for 20 days from tassel initiation (41%) and grain filling stage (34%) when compared with the irrigation without moisture stress (T7-control). The study concluded that moisture stress for 20 days from the tassel initiation stage caused more yield reduction (T4) followed by the grain-filling stage (T6). Moisture stress is more detrimental at the reproductive stage compared to the vegetative stage on maize yield.
