Design Development and Performance Evaluation of Solar Operated Pigeon Pea (Cajanus cajan L. Millsp.) Pruner

Pigeon pea (Cajanus cajan L. Millsp.) is a vital grain legume known for its contribution to food security and soil fertility. However, pruning, which enhances plant architecture and yield, remains a significant challenge in its cultivation, especially in large-scale operations. Manual pruning is labor-intensive, time-consuming, and costly, which has led to the need for mechanized alternatives, a solar-operated pruner was developed at IGKV, Raipur, to reduce labour, time, and costs. This study focuses on the design, development, and performance evaluation of a solar-operated pruner tailored specifically for pigeon pea. The pruner integrates key components such as a cutting blade, DC motor, solar panel, battery, and charge controller. A 12 V DC motor, generating 10.53 N of force and operating at 8500 RPM, ensures efficient pruning. The motor is powered by a 7.2 Ah battery, which can be charged in 4 hours using an AC adaptor or 8 hours via a 10 W solar panel. The battery allows for 4-6 hours of continuous operation. The pruner's lightweight PVC frame makes it portable and user-friendly, while the protective blade guard ensures operator safety. Performance evaluation of the pruner indicated a field efficiency of 81% and pruning efficiency of 76%. The actual field capacity was measured at 0.097 ha/h, with a walking speed of 1.2 km/h. Losses due to half-cut stems were calculated at 9.04%. The pruner demonstrated its ability to reduce labor costs, improve pruning efficiency, and promote sustainable agriculture through its solar-powered operation. This study highlights the economic and environmental benefits of adopting solar-operated pruners for pigeon pea cultivation.

Non-chemical weed management: Harnessing flame weeding for effective weed control

The goal of the current study was to create and assess the effectiveness of a hand-pulled ergonomically designed flame weeder. The developed weeder was tested in the field at three operating pressures (20, 30 and 40 Psi) and forward speeds (1.00, 1.25 and 1.50 km/h) to study their effects on plant damage, survival rates, weight preservation rates, weed management effectiveness, soil temperatures, and gas and energy consumption. Thereafter, at optimized values of forward speed and operating pressure, a comparative assessment of flame weeding with traditional methods (mechanical and manual weeding) was done in terms of weed control effectiveness, operational time, energy consumption, and cost of operation. Results showed that the optimal performance of the designed flame weeder was achieved when operated at a speed of 1 km/h and an operating pressure of 40 psi. The survival rate, weight preservation rate, weed control efficiency, change in soil temperature, recovery rate, plant damage, gas consumption, and energy consumption were observed to be 27.3 %, 32.5 %, 91.1 %, 40.74 °C, 8.5 %, 2.2 %, 4.05 kg/h, and 2500.24 MJ/ha, respectively, at optimized values of forward speed (1.00 km/h) and operating pressure (40 Psi). The actual field capacity, field efficiency and operating cost of the flame weeder were 0.0755 ha/h, 94.94 %, and 3620.81 ₹/ha, respectively. Hand weeding had the best level of weed control effectiveness, but it was a laborious, time-consuming process. When compared to manual weeding, flame weeding was 50.42 % cheaper and 94.82 % faster.

Conceptualization and development of a semi-automatic vegetable transplanter prototype for small landholdings

The process of seedling transplantation has significant importance within the realm of mechanical vegetable production in contemporary agriculture. A prototype of a two-row tractor-mounted semi-automatic vegetable seedling transplanter (SVT) was conceptualized and developed for small agricultural holdings. The functional behaviour of the prototype was examined with computer-aided design tools, and the various units of the prototype have been finalized. To develop the prototype, the feeding, metering, transplanting, drive train, and soil compacting/covering unit of the machine were developed and constructed using materials readily accessible locally. The machine has a set row-to-row spacing of 600 mm, and it may alter the plant-to-plant spacing when the machine's forward speed changes. The pace was customized to achieve the required 450 mm plant-to-plant spacing. A 12:1 speed reduction gearbox was used for the proper metering of seedlings. The effect of independent factors, namely tray cell type, feeding mechanism, soil covering/compacting wheel angle, and age of seedling, on the machine's actual field capacity (AFC) was examined. The prototype underwent preliminary field testing to assess the functional viability, and the functioning was satisfactory. The main effect of the feeding mechanism and soil covering/compacting wheel angle on AFC was statistically significant at 5 % for tomato and brinjal whereas their first-order interaction was found statistically significant on AFC for tomatoes. The findings demonstrate that this study's prototype can be marketed or used to further vegetable production studies.

DESIGN AND EVALUATION OF A LOCALLY- DESIGNED PEANUT DIGGER

Manual peanut digging in the Philippines is still a practice due to the unavailability of low-cost mechanical diggers adaptable to local field conditions. Hence, the peanut digger design and evaluation were developed. The design involves benchmarking local field practices, ANSYS analysis of the digger blade, and CAD drawing. It is designed to dig, lift, convey, and drop the peanut stalk in a windrow. Its main parts are the main frame, digger blade, belt stalk conveyor, power transmission system, and hitching system. The pulling force and power requirement for the peanut digger is 1,387.48 N and 2.0 hp, respectively. The performance measures are the belt stalk conveyor speed levels at 205 rpm, 410 rpm, and 615 rpm, replicated three (3) times with three (3) plots per replication. They revealed an actual field capacity, digging efficiency, and mechanical physical damage of 0.025 ha/h, 95.31%, and 0.56%, respectively. Investing in the machine is economically viable with a benefit-cost ratio (BCR) of 2.09, a break-even point (BEP) of 5.33 ha/yr, and a payback period of 1.60 years. This implies that digging operations wider than 5.33 ha/yr start profit generation for farmers.

Economic Analysis of Tractor Powered Manure Pulverizer cum Applicator over Traditional Manure Application Practices

Background: A well-managed manure is a valuable resource in providing nutrients for crop production. Farmers usually follow manual manure application practices which involves lot of drudgery and physical stress to pulverize as well as to apply in field. Also traditional practices results in a reduced field capacity along with higher cost of application. So there is a need to create a medium between the farmers and manure application practices by introducing manure pulverizers and applicators. Hence a study was undertaken to analyze the economic impact of a tractor powered manure pulverizer cum applicator over traditional practices. Methods: A manure pulverizer cum applicator helps in managing the manure by simultaneous pulverization and application in the field as basal application. On the other hand traditional practices involve manual dumping, clearing of lumps and spreading them in the field which require more than 3 labours to cover an acre in a day. Cost incurred with both manual and mechanical practices were calculated in terms of rupees per hour and rupees per hectare of operation. Result: The actual field capacity and efficiency of manure pulverizer cum applicator was observed to be 0.311 ha h-1 and 86.5% at a forward speed of 2.0 km/h-1. The cost of manure pulverizer cum applicator alone was Rs. 64,000. Cost of operation of manure pulverizer cum applicator as an attachment to tractor was found to be 1943.5 Rs ha-1. Cost of manual manure application followed by manure pulverization was noted as 4662.2 Rs ha-1. Saving in cost of operation was more than Rs. 2700 with tractor operated manure pulverizer cum applicator over manual application practices. The benefit-cost ratio of the developed machine was 1.4:1.

UAV was operated at 2.0 m height above the tree top.The water and oil sensitive papers were fixed on the outer side as well as inside of selected guava trees at four different canopies. Organic neem seed kernel based azadirachtin 0.15% EC biopesticide was used at recommended dose. After spraying, all water and oil sensitive papers were collected for further laboratory analysis. All spray quality parameters, i.e., coverage (%), droplet density (droplets cm-2), droplet size (µm) and uniformity coefficient were determined. For the efficacy of drone sprayer insects were counted before and 1, 2, 7 days after spray (DAS) and reduction in number of insects was calculated. Results: The on-flight field capacity of spraying with UAV was 3.0-3.3 ha h-1 whereas actual field capacity was found to be 2.0-2.3 ha h-1. The total mean coverage area was found in the range of 2.67-10.67%. The maximum coverage was at the top canopy (inner and outer) of tree which was significantly higher than all other observation points on the canopy. The mean droplet density was found in the range of 14.67-28.33 droplets cm-2. The highest droplet density (28.33 droplets cm-2) was found at the top outer side of the tree canopy. The volume median diameter was found in the range of 208.0-418.3 µm whereas, number median diameter was in the range of 138 to 269 µm. The percent reduction in aphid population 1, 2 and 7 days after spray (DAS) was 38.06, 68.28 and 62.69%, respectively whereas it was 47.95, 78.69 and 70.90% with knapsack sprayer. Interpretation: Hexacopter UAV sprayer is effective in terms of quality of spray and effective control of aphid population.

A tractor drawn mulch laying machine was developed in order to integrate the operations and fix the anomalies in terms of labour associated with conventional mulch laying operations. The prototype integrates the operations of bed making, drip line laying, mulch laying, mulch covering and punching hole on mulch in one pass. The developed prototype was evaluated at three-levels of forward speed (3.0, 5.0, 7.0 kmh-1 ), two-levels of bed width (76.2, 91.4 cm) and two-levels of dibbling hole spacing (15.2, 20.3 cm). The results of evaluation experiment for the developed machine showed that the draft requirement decreased with the increase in forward speed (3.0 to 7.0 kmh-1 ), bed width (76.2 to 91.4 cm) and dibbling hole spacing (15.2 to 20.3 cm). Field efficiency increased with increase in forward speed, bed width and spacing of dibbling holes. Although at low speed (3.0 kmh-1 ), the actual field capacity and field efficiency decreased about 57% and 5.0%, respectively while draft increased about 36 %, compared to the speed of 7.0 kmh-1 . However, at a speed of 3.0 kmh-1 , the mulch damage, un-covered mulch percentage and missing of dibbling hole decreased about 65%, 64% and 7.0 %, respectively. The standardized value of draft requirement, effective filed capacity and field efficiency were observed as 63.27 kp, 0.40 ha.h-1 and 72.7% while as percentage uncovered mulch, percentage mulch damage and percentage missing number of holes were as 3.1 %, 3.4%, 6.25%, respectively. The man-hour requirement and cost of mulching operation with developed machine reduced about 97 % and 75 % as compared to conventional method of mulch laying. Therefore, the study recommends using the developed machine to install a raised-bed, laying of plastic mulch and drip irrigation pipes on the bed and making dibbling hole for vegetable seedling transplanting at a speed of 3 kmh-1 achieved the better efficiency.

​Development and Performance Evaluation of a Two-row Mechanical Paddy Transplanter

Background: Paddy is one of the most important staple food in most south-east Asian countries. It is grown either by direct sowing or by transplanting under wetland conditions depending upon the availability of water. India produces 116.48 million tonnes of rice with a productivity of 2659 kg ha-1. Manual transplanting of rice seedlings by hand is generally done in stooping posture which is laborious and drudgery. It also requires a huge amount of labour during peak season. Considering the need and to suit the hilly region, a two-row manually operated paddy transplanter was developed. Methods: For picking the seedlings, a four-bar mechanism was selected as the basis of design. The machine construction consists of a float, seedling tray, fixed-fork type finger, chain sprocket system and lugged wheel. For operation, the operator has to rotate the crank handle which transmits the motion through the chain sprocket system and four-bar linkage which in turn picks the seedlings and plants them onto the soil. Result: The machine was tested in the actual field condition and was working satisfactorily. The designed fixed fork-type finger can hold 5 to 8 seedlings at a time. The developed machine was found to be comfortable working at a speed of 0.5 kmph. The actual field capacity of the machine was 0.02 ha/h.

Business Viability of Small Combine Harvester in Haor Areas

Haor areas are the most vulnerable areas in Bangladesh. Rice is the major food crops grown in the hoar areas despite natural threats during the harvesting period. The appropriate size of the mechanical harvester is one of the solutions to mitigate the natural calamities and labor shortage in the hoar regions. This paper examines the technical and financial performance of a small combine harvester with the aim of determining its market viability in Bangladesh's hoar areas. Based on the field test and economic assessment, data on field power, forward speed, fuel consumption, time allocation in harvesting, hire fee, and payback period of machine were determined. The study showed that the operation by width was 10% less than the operation by longitudinal. Plot length and area of the plot should be more than 25m and 400 m2, respectively, to operate the small combine harvester at full capacity. Harvesting speed ranged from 0.63-0.90 km hr-1, and actual field capacity ranged from 0.03-0.05 ha hr-1. Fuel consumption ranged from 25-32 L ha-1 due to slow cutting speed. The plant density was observed higher due to cultivating high yielding variety. The machine should be operated at a low speed, preferably walking speed, to avoid clogging in the conveying chain. The combine harvester has used 56% of the harvest time, and a remaining 44% for turning purposes and other inevitable uses. The small combine harvester recorded 1.12-1.40% loss of grain. However, grain damaged was not observed during harvesting. The small combine harvester becomes profitable for the investment cost of Tk 3,50,000 with a hiring rate of Tk 10,000 Tk ha-1 following 15 ha of harvesting area in a harvest capability of 0.04 ha hr-1. This machine is suitable for a small size of land where larger sizes of machines are inaccessible. This would offer small entrepreneur different choices of paddy harvesting mechanization to encourage future adoption of enhanced innovations.
