Abstract

India is the largest producer, processor, exporter, importer and second largest consumer of the cashew in the world. The manual shelling process is done with pedal operated cashew nut sheller in standing posture. The objective of this study was to develop the pedal operated cashew nut desheller in such way that it could operated in sitting postures to reduced the drudgery involved in the deshelling operation. The dimensions in the design of seat were used from available anthropometrics and strength data of women worker of Konkan region. The modified pedal operated cashew nut desheller was ergonomically evaluated on six women ranging from 20 to 45 years. The mean values of working heart rate, corresponding oxygen consumption, energy expenditure, per cent VO₂, ΔHR were 93.56 bpm, 0.39 l/min, 8.31kJ/min, 29.33 per cent, 10.54 bpm which were less than limit of continuous performance (LCP). The operation categorized into 'moderately heavy'. With the help of developed pedal operated cashew nut desheller, kernel recovery of cashew nut obtained 7.68 kg/day. The overall performance of the developed pedal operated cashew nut desheller was good.

Abstract

The field experiment was conducted at agronomy field DBSKKV, Dapoli, on the traditional method of paddy transplanting and manual paddy transplanter. Eight male and seven female workers were participated in this activity. The mean working heart rate (WHR) during traditional method of paddy transplanting for male and female subject were 105.9 (±4.01) and 106.97 (±3.39) bpm, respectively, While mean WHR for male workers with manual paddy transplanter was 128.44 (±12.38) bpm. The field capacity for traditional method of paddy transplanting for male and female workers were 0.0040 ha/h (40 m²/h) and 0.0038 ha/h (38 m²/h), respectively. The workloads for male and female workers was "Moderately heavy" for traditional method of paddy transplanting. The field capacity and field efficiency with manual paddy transplanter were 0.020 ha/h and 47.75 per cent, respectively, with 21(DAS) nursery. The workload was "heavy" for manual paddy transplanter. Hence, the field capacity with manual paddy transplanter was 5 times more as compared to traditional method of transplanting. The working heart rate (WHR) with manual paddy transplanter for male workers was 0.82 more as compared to traditional paddy transplanting.

Abstract

This field experiment was conducted at Agronomy field, DBSKKV, Dapoli. Three different ages of nursery as 21, 28 and 35 DAS were taken for study. Plant and field parameters were measured during operation with manual paddy transplanter (hand cranked). The 21 (DAS) nursery required less time (25 min) for upischolar_maining and preparing ischolar_main washed seedlings from area of 1 m² as compared to that of for 28 (DAS) (35 min) and 35 (DAS) (42 min) nursery. Missing of hills were also less in 21 (DAS) nursery. The field capacity with existing manual paddy transplanter (hand cranking) was 0.020 ha/h for 21 (DAS) nursery, whereas, for 28 and 35(DAS) nursery it was found 0.018 ha/h and 0.019 ha/h, respectively. Hence, 21 (DAS) nursery was found suitable for manual paddy transplanter (hand cranking).
