Bangladesh has an agrarian economy in which paddy is the dominant crop. A significant amount of field losses of paddy occurs every year due to natural calamities and a shortage of time during the harvesting period. During this study, a modification was done on locally developed BAU self-propelled reaper and its performance was compared with manual harvesting system of paddy. Several experiments were conducted in Boro paddy (April–May 2017) and Aman paddy harvesting (November–December 2017) at BAU farm of Bangladesh Agricultural University after necessary modification works in the workshop. An experiment was also conducted on Aman paddy in 2017 at BAU farm for determining manual harvesting cost. The technical and economic performances of the modified BAU self-propelled reaper were determined based on the field experiments. Results reveal that average fuel consumption, effective field capacity and field efficiency were 2.71 L/ha, 0.255 ha/h and 77.27%, respectively for the modified BAU self-propelled reaper and 2.88 L/ha, 0.25 ha/h and 75.76%, respectively for the existing BAU self-propelled reaper. These results indicated that field performances of modified BAU self-propelled reaper were better than that of the existing BAU reaper. Paddy harvesting cost was found 916 Tk/ha for modified BAU self-propelled reaper and 9200 Tk/ha for manual harvesting system. The benefit-cost ratio of the modified BAU self-propelled reaper was 2.18. Considering the technical and economic performances, modified BAU self-propelled reaper was found suitable than the existing BAU reaper.  So, the modified BAU self-propelled reaper may be introduced in Bangladesh in the commercial basis.J.

Field experiments were carried out in the Agronomy field of BARI, Joydebpur, RARS, Jamalpur and RARS, Ishurdi during two consecutive kharif seasons of 2012 and 2013 to determine the suitable plant spacing and optimum fertilizer dose for higher yield of mukhikachu. Three levels of spacing viz., 60 cm x 60 cm, 60 cm x 45 cm and 60 cm x 30 cm and three levels of fertilizer dose viz., recommended dose (3000-96-27-81-18 kg ha-1 of CD-N-P-K-S), 25% less than the recommended dose and 25% higher than the recommended dose were used as treatment variables. The experiments were laid out in factorial randomized complete block design with three replications. Results revealed that the closer spacing (60 cm x 30 cm) in combination with 25% higher than the recommended fertilizer dose gave the maximum edible yield of mukhikachu (two years average) at all locations (20.04 t ha-1, 20.75 t ha-1 and 16.63 t ha-1 at Joydebpur, Jamalpur and Ishurdi, respectively). The wider spacing (60 cm x 60 cm) coupled with 25% less than the recommended fertilizer dose produced the lowest yield (two years average). The maximum benefit- cost ratio (two years average) was obtained from the combination of the recommended fertilizer dose and 60 cm x 30 cm spacing, that were 2.93 at Joydebpur and 3.42 at Ishurdi, while at Jamalpur the maximum benefit-cost ratio (two years average) was found maximum from 60 cm x 30 cm spacing with 25% higher than the recommended fertilizer dose (3.12).Bangladesh J.

Harvesting is one of the most critical operation in carrot cultivation because it is labour intensive (350 – 450 man-h/ha) and time consuming for the farmers. The present study was undertaken to evaluate the performance of single row tractor operated carrot digger designed by department of Farm Machinery and Power Engineering, COAE&T, CCS Haryana Agricultural University, Hisar, Haryana, India. The developed digger consisted of a digging, conveying, de-topping, collector and power transmission units. The carrot digger can be operated with 35 horse power tractor. It was evaluated under three variables viz., three digging blade angles (15°, 18°, 21°), three conveyor angles (25°, 35°, 45°) and three shoot catch heights (2, 4, 6 cm). The optimum value of variables obtained for operation of carrot digger were blade angle of 21°, conveyor angle of 250 and shoot catch height of 2 cm. Effective field capacity of the digger was 0.11 ha h-1 with field efficiency of 61.70 %. The digging efficiency, cut carrots, bruised carrots, picking efficiency and cutting efficiency of de-topping unit were 100, 0.62, 0.90, 62.29 and 100%, respectively at optimized value of operational variables. The labour requirement with developed carrot digger and manual method of harvesting was found 27 and 450 man-h ha-1, respectively. The operational cost of carrot digger was found Rs. 8242 ha-1 and it saves time and cost of operation in comparison to manual method of carrot harvesting. The break-even point, payback period and benefit cost ratio were 234 hours, 2.21 years and 1.56, respectively when operated for 400 hours annually. The carrot digger works better if carrots are sown in single row on the ridges rather than the broadcasting method.

Field experiments were conducted during summer (April to June), 2010 and 2011 to study the effect of post-emergence herbicides in irrigated blackgram (ADT 5). Treatments comprising of three levels (50, 75 and 100 g /ha) of the post- emergence herbicides viz., Imazethapyr 10% SL and Quizalofop ethyl 5% EC were tested alone and in combination and compared with hand weeding twice on 15 and 30 DAS(farmers’ practice). Herbicides were sprayed on 15 DAS when the weeds were 2-4 leaves stage using flat-fan nozzle as per treatment schedule. The results revealed that minimum total weed density (8.44) and weed dry weight ( 27.2 g/m2) and higher weed control efficiency (84.4%) were obtained under combined application of imazethapyr and quizalofop ethyl as tank mix at 100 g /ha. However, this was comparable with application of both the herbicides at 75g /ha. Application of imazethapyr + quizalofop ethyl each at 75 g/ha registered significantly taller plants, higher dry matter production, more number of pods per plant, seeds per pod and higher grain yield (826 kg/ha), net returns (Rs.26621/ha) and benefit cost ratio (2.76). Thus, application of post- emergence herbicides imazethapyr + quizalofop ethyl each at 75 g /ha as tank mix on 15 DAS could be recommended for controlling of emerged weeds in irrigated blackgram.

Modern agriculture requires a modern approach which responds to the necessity of mankind. The study presents the fabrication and performance evaluation of a cassava grater with  juice extractor. Such performance evaluation was conducted to determine its grating and juice extracting capacity and efficiency. It was made from locally available materials then tested experimentally using cassava with a grating capacity of 160 kg/hr. The study employed the Complete Randomized Experimental Design (CRD). In evaluating the experiment, the Two-way Analysis of Variance (ANOVA) was used to determine the significant effect of each factor and the Tukey’s test was used to determine the significant difference between the combined treatments. Two factors with different levels were treated upon the experiment.  These were mainly soaking time (0 min, 5 min, 10 min, 15 min) and the way the cassava was grated and juice extracted (Machine, Manual).  Among these treatment combinations, the soaking time of 15 minutes obtained the highest grating and extracting capacity as well as for the grating and extracting efficiency leaving its quality and acceptable appearance on top.  The computed benefit-cost ratio of 1.86 showed that grating and extracting cassava juice using the cassava grater with juice extractor was highly profitable and economical for local cassava producers.

The present study for performance evaluation newly developed varieties of CIM –Kranti and other varieties of menthol mint cultivation has been carried out at farmers’ field of central Uttar Pradesh. Mints are commonly used as the source of fragrance, flavor and pharmaceuticals industry. During the study period 2017-18, 100 farmers cultivating CIM-Kranti and other varieties have been selected from the region of central Uttar Pradesh. The primary data were collected from the selected farmer’s field on profitability comparison between CIM-Kranti and other varieties under cultivation. The highest area and production has been observed during 2012 and 2013. Simple statistical tools and techniques have been used for data analysis of the cost of cultivation and profitability. It has been observed during the study that CIM-Kranti gives higher returns (.98491/- ha/year) over other varieties (.70977/-ha/year). However, the input cost of CIM-Kranti is higher than other varieties of the crop but the net return of CIM-Kranti was more profitable than other varieties. The benefit cost ratio has been observed 1.45 and 1.74 of other varieties and CIM-Kranti respectively. The new variety “CIM-Kranti” of menthol mint is cold and frost tolerant and has the potential to produce 10-15% more oil i.e. 145-160 kg/ha in summer season as compared to all other popular commercial cultivars of menthol mint.It is suggested from the study that maximum profit is generated through CIM-Kranti cultivation followed by other varieties crop.
