Background: Karnataka is predominantly known for cluster bean production. The evidences claims that the cluster bean production is not a profitable option and has many constraints, which hinders farmers to take up this enterprise. The current study aims to analyze the growth in area, to forecast seed demand and to work out the economics of cluster bean production in Karnataka. Methods: The current study was based on the field survey conducted in Karnataka during 2019-20, to collect the primary data from cluster bean entrepreneurs. The study has also used secondary data for analysis. Four major districts in Karnataka were selected for the study, based on the maximum area and highest production. From each district, 30 farmers were randomly selected for collection of primary data, constituting a total of 120 farmers. The Compound Annual Growth Rate and cost-returns techniques were employed for data analysis. Result: The study indicated that Karnataka has registered a declined trend of 3.12 per cent per annum and the total estimated area under cluster bean would be 2,720 ha during 2021-22. Hence, the seed industry should cater seed demand to the tune of 544 quintals for the said period. Total cost of cultivation was worked out to be ₹ 35,176 per acre. The study emphasize that this enterprise provides higher gross and net returns to the tune of ₹ 70,851 and ₹ 35,675 per acre, respectively, with the Benefit-cost ratio of 2.01, indicating its profitability. Lack of availability of High Yielding Varieties/hybrid seeds and high wage rate were the major constraints notified in cluster bean enterprise.

Krishi Vigyan Kendra laid down Front Line Demonstration in the year 2010-11 and 2011-12 introducing new, high yielding and scented variety “Pusa Sugandha-3” and applying scientific practices in their cultivation. The FLDs were carried out in village “Dainiha” of Sidhi district in supervision of KVK scientist. The productivity and economic returns of paddy in improved technologies were calculated and compared with the corresponding farmer's practices (local check). Improved practices recorded higher yield as compared to farmer's practices. The improved technology recorded higher yield of 30.83 q/ha and 32.65 q/ha in the year 2010-11 and 2011-12, respectively than 22.13 and 24.21 q/ha. The average yield increase was observed 37.15 per cent. In spite of increase in yield of paddy, technology gap, extension gap and technology index existed. The improved technology gave higher gross return (37020 and 39180 Rs./ha), net return (16820 and 18920 Rs./ha) with higher benefit cost ratio (1.83 and 1.93) as compared to farmer's practices. The variation in per cent increase in the yield was found due to the poor management practices, lack of knowledge and poor socio economic condition. Under sustainable agricultural practices, with this study it is concluded that the FLDs programmes were effective in changing attitude, skill and knowledge of improved package and practices of HYV of paddy adoption.

Lack of good-quality planting materials has been identified as the most severe problem militating against increased agricultural productivity in sub-Saharan Africa (SSA) and beyond. However, investment of research efforts and resources in addressing this menace will only be feasible and worthwhile if attendant economic gains are considerable. As a way of investigating the economic viability of yam investment, this research has been initiated to address problems confronting yam productivity in eight countries of SSA and beyond: Nigeria, Ghana, Benin, Togo, Côte d’Ivoire, Papua New Guinea, Jamaica, and Columbia. Research options developed were to be deployed and disseminated. Key technologies include the adaptive yam minisett technique (AYMT), varieties adapted to low soil fertility and drought, nematode-resistant cultivars (NRC), and crop management and postharvest practices (CMPP). This article aims at estimating the potential economic returns, the expected number of beneficiaries, and poverty reduction consequent to the adoption of technology options. Estimates show that the new land area that will be covered by the technologies in the eight countries will range between 770,000 ha and 1,000,000 ha with the highest quota accounted for by AYMT. The net present value will range between US$584 and US$1392 million and was highest for the NRC. The CMPP had the lowest benefit-cost ratio of 7.74. About 1,049,000 people would be moved out of poverty by these technologies by 2037 in the region. These technologies are less responsive to changes in cost than that in adoption rate. Therefore, the realization of the potential economic gains depends on the rate and extent of adoption of these technologies. Giving the knowledge-intensive nature of some of these interventions, capacity building of potential adopters will be critical to increasing the sustainability of the yam sector, thereby enhancing food security and reducing poverty.

AbstractIn order to enhance sustainable intensification of potato-based cropping systems, especially in sub-Saharan Africa (SSA), there is a need to investigate the economic viability of investing in this lucrative venture. This study evaluated the economic returns under legume intercropping systems using value/cost ratio (VCR) and benefit/cost ratio (BCR) under treatments comprising of potato intercropped with dolichos (Lablab purpureus L.) (P-D), climbing bean (Phaseolus vulgaris L.) (P-B) and garden pea (Pisum sativum L.) (P-G), and a potato pure stand control (P-S). Across the seasons, tuber yield was not significantly (p < 0.05) affected by intercropping with P-D, whereas under P-B and P-G, it decreased by 19% and 16%, respectively compared to P-S. P-G, P-B and P-D recorded 6, 7 and 12% higher potato equivalent yield (PEY) relative to P-S. P-D was the most profitable intercropping system with VCR of 35 and BCR of 5.1 as compared to values recorded in P-S of 31 and 5, respectively. Regression of VCR against PEY resulted in a stronger coefficient (0.98) compared to that of BCR against PEY (0.82) implying that VCR is a simple tool that could be adopted for economic returns to investment studies such as potato-legume inter-cropping systems.

La evaluación de las pesquerías es a menudo problemática debido a que los parámetros de las poblaciones explotadas son poco conocidos o desconocidos. La mayoría de las evaluaciones se limitan al aspecto biológico, ignorando en la mayoría de los casos los aspectos económicos y sociales de la pesca. Los resultados de las evaluaciones tienen en cuenta los datos facilitados por el usuario, lo que debería ser una imagen precisa del aspecto socio-económico del caso de estudio. Así, en la actualidad se utiliza esta información para producir resultados que describen las consecuencias más probables después de cualquier cambio en la estrategia de manejo que se proponga. La evaluación de las poblaciones mediante el modelo FISMO (FIsheries Simulation MOdel) se basa en los principios generales de la evaluación de recursos pesqueros y se realiza con datos históricos de la captura en toneladas de peso fresco. Así, con el propósito de formular mejores opciones de administración, se realizó un meta-análisis de dato para evaluar el desempeño de las pesquerías con base en este modelo de simulación. En cada una de dichas opciones se utilizan datos históricos de la captura y los valores de los parámetros de población. Los costos asociados y los beneficios económicos de cada pesquería son tomados como referencia para el análisis bio-económico. El modelo propuesto permite la prueba de tantas posibilidades de explotación como la pesca y los datos lo permitan, en un ejercicio de programación dinámica que puede proporcionar respuestas a preguntas lógicas como ¿Qué pasará con la biomasa del stock y del rendimiento económico si la talla de primera captura se incrementa? ¿Cuáles serán las consecuencias biológicas y económicas si se duplica el esfuerzo de pesca? ¿Cuál es el esfuerzo máximo que puede soportar la pesquería y dejar de ofrecer beneficios de por lo menos el 10 por ciento por encima de los costos? y ¿Cuáles son las expectativas económicas de la próxima temporada si aumenta el costo de los combustibles en una proporción determinada? A numeric model for the sustainable management of fisheries Usual management targets of many fisheries worldwide are addressed to maintain exploitation at fishing intensities required for the maximum sustainable yield (FMSY). However, variability induced by climate variability and economic forces, often lead to over exploitation. Traditional assessment procedures are limited to the assessment of the biological aspect of fisheries and the socio-economic and social aspects of fishing activities are generally ignored; however, this is an economic activity and in contrast, stakes holders ignore the stock dynamics pursuing economic benefits only. This imposes a gap in the knowledge required for a complete management process. The FISMO is an assessment and management tool that allows forecasting the most likely outcome after the application of any feasible management decision by changing F and the age of first catch (tc). It uses as input historic records of catch data, parameters of the von Bertalanffy growth model, and of the length-weight. Also, socio-economic variables of the last fishing season, such as the number of boats, length (days) of the fishing season, and number of fishers per boat. The model outputs of any target are catch, stock biomass, fishing effort, economic returns, benefit/cost ratio, number of boats, number of fishers and number of fishing days. FMSY , FMEY, and B/C at the economic equilibrium level are found combining F and tc and many management options, useful for planning and co-management, with very reasonable accuracy, can be chosen without compromising the sustainability of the fishery. The software is user-friendly and can be adapted to practically any fishery.

Cluster bean is an important legume cultivated mostly on marginal and sub marginal lands of arid and semi-arid regions. Overall, India produces around 80% of global cluster bean production. It is cultivated on more than 4 m ha in India, Rajasthan alone accounts for around 80% of the area and production. Owing to its demand in the international market, it has been introduced in the non-traditional growing areas like Andhra Pradesh, Tamil Nadu, Karnataka, Maharashtra and Chhattisgarh. Further, its cultivation is also being taken up under irrigated conditions during summer. Cluster bean seed (endosperm) is a source of a natural hydrocolloid (galactomannan/‘guar gum’). The gum has unique abilities with multiple commercial applications like textile, printing, paper, cosmetics, mining, pharmaceutical, petroleum, natural gas, well drilling and oil industries. Green pods are nutritionally rich and are routinely consumed as vegetable especially in northern and western parts of India. Additionally, cluster bean has been reported to have beneficial effects when cultivated as an intercrop. Cluster bean meal (high protein content) obtained from seed coat and germ cell is an excellent feed for monogastric animals. Cluster bean cultivars with high gum content (>32%) and viscosity (4000-5000 cps) are more preferred for export. The value of cluster bean exports from India has increased from Rs 242 crores (1994) to Rs 2100 crores (2012-13). This review presents the various aspects of cluster bean cultivation and its emergence as an important industrial crop.
