Upscaling and Evaluation of BARI Inclined Plate Planter

Abstract

The BARI inclined plate planter was developed for one pass tillage and seeding operation. But the planter was not capable of planting small seeds as seeds were entering between the plate and base. So, six additional MS base plates were incorporated in the planter. Three plates were redesigned and fabricated for maize seed (9 cells); for wheat, mungbean, lentil, jute, etc (32 cells) and for rice seed (11 cells). Changing of inclination of the plate is needed to use same (32 seed cell) plates for different crops and to calibrate the planter for 10% more or less seed than the predefined rates. Field test of BARI developed inclined plate planter was conducted in Gazipur, Pabna, and Barisal and its performance were evaluated. The planter was tested for sowing maize, wheat and mungbean during 2011-12. Effective field capacity and field efficiency were 0.17 ha/h and 75%, respectively. Coefficient of seed distribution uniformity and coefficient of planting depth uniformity were 97 and 94%, respectively. Time and cost saving to complete land preparation and planting of maize by inclined plate planter were 90 and 86%, respectively than conventional hand planting. The payback period of the BARI planter is 1.20 year. Break-even use time is 97 hours.

Mustard production with different tillage practices at Jamalpur

“…To meet up the edible oil requirement of the country, mustard production should be increased, which is possible by proper tillage cum seeding practices as found in this research. BARI seeder accounted minimum time for seeding and also cost (Hoque and Miah, 2015). The most crucial task in agricultural crop production is soil tillage, which can greatly enhance soil aggregation, encourage crop root growth, and help reduce soil erosion (Jin et al, 2023 andMosaddeghi et al, 2009).…”

“…In conventional agriculture, land preparation takes about two weeks (Hoque and Gathala, 2018). The seeder also showed better performance for sowing seeds (Hoque et al, 2009;Hoque and Miah, 2015), which can be used for small to large seed sowing and planting (Hoque and Karim, 2016).…”

Design and Experiment of a Single-Row Small Grain Precision Seeder

“…Cujbescu used the mathematical model to numerically simulate the working process of the pneumatic seed-metering device, and analyzed the movement of the seeds according to the angle of detachment, the height of detachment of the seed, as well as the speed of the seed in its trajectory towards the channel opened by the coulter (Cujbescu et al, 2022). Hoque developed a tilt-plate seeder, which has been tested to save 90 % of time and 86 % of cost compared to manual planting, with a payback period of 1.2 years (Hoque et al, 2016). However, foreign millet planting area is relatively small.…”

Modified strip tillage blades for two-wheel tractor seed drills improves maize crop establishment under conservation agriculture

“…When used in combination with mulching and crop rotation, PTOS aided strip tillage can be considered a conservation agriculture (CA) practice ( Hossain et al, 2015 ; Gathala et al, 2015 , 2016 ; Islam et al, 2019 ; Hoque and Miah, 2015 ). A number of studies have evaluated PTOS-based strip tillage of wheat, maize, mungbean and chickpea, but with varying results depending on the crop, soil type, and degree of soil moisture, among other factors ( Esdaile, 2010 ; Hossain et al, 2009 ; Hoque and Karim, 2015 ; Krupnik et al 2014 ; Gathala et al, 2020 ). However, technical improvements in PTOS engineering are needed to arrive at optimal blade designs, rotary speed, and suitable furrow openers with an appropriate seed metering systems to optimize crop establishment and assure efficient and low-cost strip-till seed drills that can be accessible to farmers in Bangladesh ( Krupnik et al, 2013 ; Siddique et al, 2012 ).…”
