A REVIEW ON CROP IMPROVEMENT STRATEGIES AND BREEDING METHODS IN ORNAMENTAL ANNUALS

Paper ID- AMA-18-01-2024-12850

The availability of a broad variety of cultivars in many ornamental species has increased recently, particularly for attractive annuals, which are valuable commercially for their use as cut flowers, potted plants, loose flowers, and landscape gardening. The breeding of ornamental plants currently is a challenging endeavour with constantly evolving new obstacles. Modern genomic technologies provide opportunities for enhanced precision breeding and selection for harder-to-quantify features. Traditionally, the goals of ornamental breeding have been to increase resistance to biotic or abiotic stress, novelty, yield, and quality. But accomplishing these objectives has frequently necessitated tedious crossbreeding, and exact breeding methods have been underapplied. Developing scientific and commercial interest in ornamentals have been generated by recent developments in plant breeding techniques such as genome editing, somaclonal variation, chromosome doubling, molecular marker assisted breeding, mutation breeding etc., especially with regard to changing desirable plant features and creating new ornamental traits of the crops.

Design and Analysis on M-PID Real-time Control System with Forced Read and Write Mode

Paper ID- AMA-17-01-2024-12848

As a non-linear resistor with memory characteristics, the memristor plays an important role in areas such as image processing, pattern recognition, secure communication and intelligent systems due to its non-volatile storage and variable resistance. Currently, the research of memristor in memristive neuromorphic circuit is becoming more and more mature, but its application to the real-time control system needs to be improved. This study focuses on the proportional-integral-differential (PID) controller and combines the memristor with it to design a Memristive PID (M-PID) control system that can be used for the real-time control system. First, the Time-division Multiplexing (TDM) is used to separate the control system working circuit signal from the memristor trigger circuit signal, which can effectively avoid mutual interference between high frequency and low frequency signals. Second, using the Metal-Oxide-Semiconductor (MOS) transistor's own switching threshold, a threshold memristor control circuit with a “zero state” interval is designed, which can effectively avoid system oscillation caused by frequent switching of the PID controller. Third, a memristor forced read/write mode is proposed, which improves the lifetime of the memristor and simplifies the memristor control circuit. Using MATLAB simulation software, a second-order system is selected as the controlled object, and the proposed scheme is simulated and verified. The results show that the proposed scheme is reasonable and feasible, and can provide certain technical support for the commercial application of the memristor.

Economic and environmental impact of Arecanut based cropping system on the farming community of north eastern sub Himalayan tract of west Bengal

Paper ID- AMA-16-01-2024-12847

The agriculture system is under pressure due to climate change and its hurdle in achieving food, income, and environmental security with increasing rate of population. For this context it needs to improve the crop productivity per unit area through using available space vertically and horizontally along with other natural resources. Arecanut based cropping system (ABCS) is a perspective modern and alternative approach for sustainable productivity in horticultural crops for 85% small and marginal farming community of the North Eastern part of the country, not only providing greater economic return also playing better role in sustainable land use management and in better climate change mitigation through sequestering atmospheric CO2 in terrestrial ecosystem. Integration of different intercrops of annual and perennial nature were made for effective utilization of 70% left over land area and 40% of the incident solar radiation penetrating down within the canopy of the plantation. Various component crops of different ABCS models with their diverse carbon sequestration potential ultimately resulted into distinct total CO2 sequestered by one hectare model with different crop combination ranging from 280.77 to 313.96 t/ ha having lowest value under mono cropping situation with only arecanut (248.31 t/ha). The findings of the present study proved the weakness of monocropping and dictate towards adoption of high-density cropping system not only in terms of economic feasibility of the small and marginal farmers of North Eastern parts of West Bengal but also mitigating environmental issue related to emission of greenhouse gases. Economic assessment in different ABCD contributed better economic return.

Exploring agro-morphological traits for yield attributing factors in rice landraces

Paper ID- AMA-15-01-2024-12846

This study characterized thirty-five rice landraces and six checks for agro-morphological traits associated with yield, conducted at the College of Post Graduate Studies in Agricultural Sciences, Central Agricultural University, Meghalaya during the kharif season of 2022. Traits such as Days to 50 % flowering (DTF), Filled grain per plant (FGPP), Plant height (PH), Panicle Length (PL), Panicle number (PN), Plot yield (PY), Spikelet Fertility (SF) and Spikelet per panicle (SPP) were evaluated using Augmented Randomized Complete Block Design. Analysis revealed significant differences among treatments, checks, and treatment vs. check for all traits. Moderate genetic variability was observed, emphasizing the need for further improvement through hybridization and selective breeding. High heritability coupled with genetic advance highlighted the role of additive gene effects. Correlation analysis identified positive relationships between yield and traits viz FGPP, PL, PN, and SPP. Principal Component Analysis and cluster analysis aided in grouping landraces based on traits, offering valuable insights for future breeding programs. The study contributes essential information for identifying and selecting promising landraces for improving rice yield.

IMPACTS OF VARIETIES AND THEIR BIOCHEMICAL PARAMETERS ON POD DAMAGE BY BORER COMPLEX IN PIGEON PEA IN EASTERN INDIA

Paper ID- AMA-15-01-2024-12845

To understand the impact of varieties and their biochemical parameters on pod damage in pigeon pea, the field experiments were conducted to evaluate thirteen pigeon pea varieties at Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal, India. The experiment was laid out in randomized block design with three replications. Fifty pods had been harvested for recording pod damage by borer complex at three developmental stages of pod viz. pod formation, pod filling and pod maturity. Results revealed that among the tested varieties, MA6, Pusa 9, Pusa 991, CORG 9701 recorded lower pod damage in comparison to the other varieties. Pod damage caused by Helicoverpa armigera on MA6, Pusa 9, Pusa 991 and CORG 9701 were recorded from 2.35 to 2.82%, 7.33 to 9.07% and 15.82 to 19.55% at pod formation, pod filling and pod maturity stages, respectively whereas the corresponding values for Melanagromyza obtusa were 13.01 to 18.85%, 23.03 to 31.30% and 26.73 to 36.84%, respectively. It was evident from the regression studies that the Helicoverpa population can be explained by total seed protein content up to 87.4 % whereas for pod fly protein content can explain the average population up to 82.2 %. The total seed phenol content can explain the Helicoverpa population up to 83.60 % whereas the same can be explained up to 68.8% for pod fly. The seed protein content was directly proportional and seed phenol content was inversely proportional with the average population of all insect pests.
