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.

Design and experiment of impeller seed guide device for rice internal suction hole direct seeding device

Paper ID- AMA-15-01-2024-12843

Multi-grain hole-forming sowing and uniform hole spacing are important agronomic requirements for precise hole-direct seeding of rice. However, the traditional tubular seed-guiding device has problems such as poor hole-forming ability and large coefficient of variation of hole spacing in multi-grain hole-forming direct seeding of rice, especially for the internal suction seed-metering device with high-position seeding. Based on the structural characteristics of the suction component of the internal suction seed-metering device, this paper innovatively designs a kind of impeller type seed guiding device. The main structural parameters of the impeller seed guide device were analyzed by constructing the kinematics model of the rice seed in the impeller seed guide process. Taking the long-grain rice variety Chuangliangyou 4418 as the seeding object, the effects of inner impeller radius, blade offset angle and seeding angle on the hole-forming and seeding-guiding performance of impeller seeding-guiding device were studied by bench seeding test. The optimal structural parameter combination of seeding-guiding device was determined as inner impeller radius 56 mm, blade offset angle 11 ° and seeding angle 36 °. On this basis, the seeding performance test of different seed guiding devices of internal suction seed-metering device was carried out by using rice seeds with different external dimensions. The test results show that the impeller has better cavitation and hole spacing uniformity than the seed guide tube. The average hole diameter is not higher than 21.7 mm, the qualified rate of hole diameter is not lower than 96.1 %, and the coefficient of variation of hole spacing is not higher than 10.1 %. Compared with the seed guide tube, which is increased by 32 %, 16 % and 34 % respectively, And the average hole distance is about 200 mm in theory. The impeller seed guiding device proposed in this paper can improve the problem of poor performance of fixed-distance multi-grain hill-seeding in the tubular seed guiding device, and meet the seeding requirements of precision hole-direct seeding of rice. It provides a theoretical reference for the design of seed guiding device for one-hole multi-grain hole-direct seeding crop.

Evaluation of Pigeonpea (Cajanus cajan L.) genotypes for seed quality traits and seed health status during storage in Prayagraj region (U.P.)

Paper ID- AMA-14-01-2024-12842

The experiment was conducted during 2019–2020 at SHUATS, Prayagraj, with 17 genotypes of pigeonpea and one control variety (encoded with G1 to G17) taken from IIPR, Kanpur (U.P.). Prior to storage, the seeds were treated with mustard oil (T1) and carbendazim (T2) and stored for up to twelve months. The untreated seeds (T0) were used as the control. Under controlled laboratory conditions, 51 treatment combinations were tested using a Complete Randomized Block Design (CRD) with 4 replications for seed quality attributes and seed health status during storage (6 and 12 months, respectively). After the storage period, seeds were evaluated in terms of their qualitative attributes and health status. The highest percentage of germination, seedling parameters, vigour indices, and a low incidence of disease were determined by the mean sum of squares of treatment combination T47 (T2G13), which demonstrated significant differences for the given characteristics under this investigation at the 5% level of significance. The loss of seed (Vigour, Viability, and Nutrients) during storage is a serious problem due to infection and deterioration, which results in low germination, poor health, and poor seed set/production. This phenomenon can be checked & stopped at a certain level by various treatments that prevent seed deterioration. The study revealed that mustard oil had little influence on quality attributes and seed health, whereas carbendazim had the greatest effect on all of these characteristics.

Assessment of Profitability and Sustainability in Integrated Farming Systems: A Case Study in Meghalaya, India

Paper ID- AMA-12-01-2024-12838

This comprehensive study delves into the intricate dynamics of three Integrated Farming System (IFS) models implemented in the Ri-Bhoi District of Meghalaya, India, focusing on Marngar and Sarikhusi villager clusters under the Farmers' First Programme (FFP). Spanning the years 2017 to 2023, these models, designated as IFS I, IFS II, and IFS III, integrate various agricultural enterprises, including fishery, poultry, piggery, dairy, crops, goatery, and mushroom farming. The results reveal a remarkable transformation in the economic landscape for small and marginal farmers adopting these IFS models. In the case of IFS I, covering a 2.47-acre farm, the annual gross income surged from Rs. 1.73 lakhs to an impressive Rs. 6.23 lakhs post-intervention. IFS II, operating on a 1.4-acre farm, showcased the effectiveness of integrating diverse enterprises. The model, incorporating piggery, fishery, poultry, duckery, crops, goatery, and mushroom farming, demonstrated a commendable average annual gross income of Rs. 3.60 lakhs. In the case of IFS III, which encompassed crops, fishery, poultry, and piggery on a 1.10-acre farm, the results indicated an almost twofold increase in annual gross income compared to the baseline. The benefit-cost ratio for IFS III was calculated at 2.38, affirming its profitability. The implications of these findings extend beyond the specific regions studied. Policymakers and agricultural extension services can leverage these insights to design and implement similar interventions in diverse agro-ecological contexts, aiming to promote sustainable agricultural practices. The success of these IFS models suggests a scalable and replicable approach that could contribute to holistic agricultural development and poverty alleviation in various rural settings.
