The agrobiological and physico-mechanical properties of leguminous seed plants do not allow them to be harvested without loss exclusively by combine technologies. One way to increase the productivity of the seed production process is to include stationary machines in the assembly technology for wiping and separating seed heaps. Combining these important operations with one machine will further increase the efficiency of legume seed production technologies. This work is devoted to considering ways to increase the efficiency of air-centrifugal separation and dust cleaning seed heaps. A review of recent studies and publications has shown that there is a sufficient methodological basis for determining the parameters of the process of separation of the heap and purification of the exhaust air. An analysis of the publications made it possible to determine the purpose of the research, which is to increase the efficiency of the grater-separation unit by substantiating its scheme and the method of theoretical determination of the parameters of the separation process. According to the results of previous studies, a structural scheme of the grater-separating device is proposed. The main elements of the block are a grater device, which consists of a motionless and movable corrugated discs of the separating device with separate channels for the exit of seeds, straw part of the heap, air. To increase the efficiency of the cleaning process, a blade swirler and a louvre nozzle are placed in the separating device, which provide the air flow with rotational movement around the axis of the cyclone body. In theoretical studies of the motion of particles in a rotational air flow, the simplified assumption was adopted: the particles are spherical, do not deform, and do not interact with each other, the inertia force is directed along the radius of the cyclonic chamber, the tangential and axial components of the particle velocity are equal to the corresponding components of the air velocity, and the particle resistance force determined by the Stokes law, the force of attraction is much less than the centrifugal force, so we neglect it. The obtained formulas allow one to approximately determine the parameters of the cyclone device that will ensure the separation of the seeds of legumes.

Aim: To assess the Knowledge level of Onion growers on Improved Onion production technologies and to find out the Relationship between personal, socio economical and psychological characteristics of onion growers with their knowledge level. Study Design: “Ex-post facto” research design. Place and Duration of the Study: The present study was conducted during 2017–18 in Gadag district of Karnataka. Methodology: Two villages from each of the four Taluks of Gadag district were randomly selected and from eight villages, 15 respondents were selected from each village by adopting random sampling method to form a sample of 120 farmers. Data was collected from the respondents by personal interview method using a pre-tested structured interview schedule. Results: Majority of the farmers have medium level (42.50%) of knowledge followed by high level (31.66) of knowledge. Further study revealed that farmers had cent percent knowledge on seed rate, time of sowing, irrigation and weeding, whereas low level of knowledge on transplanting (10%), fertilizer dose (10%) and plant protection (15%). Independent variables like, Education, Mass media exposure, Extension contact, Management Orientation were have significant relationship with knowledge level of onion growers at 1 per cent level of significance, While Age, Farming experience, Innovativeness, Extension participation, Social participation and Risk Orientation at 5 per cent level of significance and variables such as Family size, Land holding , Area under Onion cultivation, Annual income exhibit non-significant relationship with knowledge level of onion growers. Conclusion: Significant portion of respondents were having medium level of knowledge with most of the independent variables contributing significantly towards their knowledge level on improved onion production technologies.

Sewan grass (Lasiurus scindicus), a popular pastoral species, is getting some much-needed attention as mechanization, modernity in agriculture, and illicit grazing pose severe risks to biodiversity conservation in arid and semi-arid areas. It is found mainly in wastelands, dunes, hammocks, and sandy plains but less popular for cultivation in farmer’s fields. Sewan grass has many features like good nutritional value, soil binder, tolerance to high temperature, high digestibility and palatability, and prolonged drought conditions contributed greatly towards its success as a potential forage species in arid environments. It contains significant quantities of crude fibres, lignin, minerals and crude protein, and varies in the proportion of their tissue that can be digested by ruminants. Most research focuses on the species as a forage plant and agronomical practices and is largely published in agricultural and grey literature. Meanwhile, there is a lack of information about breeding strategies and seed production technologies. Therefore, here we present a comprehensive review about agronomic management, breeding, and seed production strategies systematically that will aid in the management of sewan grass now and into the future.

Abstract.The sugar beet seed production is currently employing a non-planting-and-transplant technology with the use of steklings. Planting units of the machines available on the market feature a number of drawbacks: low productivity, possible injuring of root crops, and increased labor intensity of operators. (Research purpose) To develop a universal design and parameters of an increased-productivity unit for planting steklings of sugar beet and other root crops. (Materials and methods) The design scheme and type of a planting unit have been chosen according to the requirements of applicability and versatility. Its preferred design parameters have been calculated as well. A prototype machine with a universal planting unit in the form of a cellular disk has been developed and manufactured in test production. (Results and discussion) The conducted field experiments proved the versatility of a planting machine with a disc-type unit used for planting root crops, including dimensional characteristics corresponding to those of steklings. The authors have found that when replacing a disk with a different number of cells of different sizes, the machine is suitable for planting a number of similar crops. A removable disk with 12-16 cells has been installed, with its angular speed decreased to 0.393-1.180 radian per second, which is lower as compared to the existing machines. Satisfactory agrotechnical tolerances have been provided for carrot planting in the soil at a depth of 12 cm, a step of 30 cm, and a deviation from the vertical of 110. The intensity of root crop laying in the cells of a seeding disk has been increased to 1-3 pcs. per second. (Conclusions) It has been found that the machine and the planting unit can increase the working speed up to 1.0 meter per second and reduce the labor intensity of operators to the level of safety requirements. The use of universal machines in the breeding and seed production of root crops will reduce the range of the applied machines and operating costs of farm enterprises.
