Abstract/ Executive Summary:

A field trial was carried out at Farm Machinery Technology Dissemination (FMTD) project site, Sujanagor, Pabna to test performance of planting methods with Bangladesh Agricultural Research Institute (BARI) inclined plate planter, BARI Bed planter over conventional manual planting method for sowing lentil during 2014-15. Mechanical planting method with BARI Inclined Plate Planter showed highest yield (1.67 tha^-1) whereas it was obtained 1.54 tha^-1 for bed planter and 1.41 tha^-1 for conventional manual planting method. Planting methods exhibited non significant response on yield attributes like number of plants population, plant height, seed pod^-1, dry weight of 10 plants and weight of 100 seeds. However, highest no. of pod plant^-1 (168.83), primary branch (6.77) and secondary branch (33.67) was obtained from planting by IPP and these three parameters were shown lowest value (70.20, 3.5 and 11.8 respectively) in manual seeding methods. Total Cost of complete land preparation and planting was exhibited lowest for seed sowing with BARI Inclined Plate Planter (2016 Tk. ha^-1) and it was 2727 Tk. ha^-1 for BARI bed planter and highest for conventional manual seed sowing method (4433 Tk.ha^-1).

Keywords: Field performance, BARI inclined plate planter, Field efficiency, Crop yield

Location: Farmer's field of FMTD project site, Sujanagor, Pabna

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Crop-Soil-Water Management

Commodity: Lentil

Objectives:

The present experiment was conducted to fulfill the following objectives: a) to evaluate the field performance of BARI inclined plate planter (set up with BARI high speed rotary tiller and bed former) in farmers’ field b) to ascertain field efficiency and crop yield under these planting methods.

Methodology:

The experimental trial was conducted at farmer's field of FMTD project site, Sujanagor, Pabna during 2014-15. One unit of power operated inclined plate planter and one unit of bed planter fabricated by Farm Machinery and Postharvest Process Engineering Division, BARI, Joydebpur, Gazipur was engaged for field performance test. The planter was tested for sowing lentil. Seed metering plates were made by using plastic material. Before testing the planters in field, it was tested in OFRD, ARS, Pabna machinery testing field and the seed rate was calibrated as the following formula. Field performance test Field performance test of the planter was conducted in farmers field located in Sujanagar, Pabna for sowing of lentil. The variety of lentil was BARI Moshur-5. The seeds were sown on 30 October 2014. There were three treatments as T1= seed sowing with Inclined plate planter (IPP), T2= Seed sowing with Bed Planter (BP) and T3 = Conventional Manual seeding (MP).The experiment was laid out in randomized complete block design with three replication. Seed rate were 30 kgha1and line to line spacing was 30 cm for mechanical sowing and 33.75 kgha-1 for manual sowing respectively. Tilling, bed formation, seed placement and laddering cum seed covering operations were done at a time in single pass of the machine. Time and cost required for complete land preparation and seed sowing by inclined plate planter and bed planter compared to traditional seeding were recorded. According to Seed placement rate, germination rate was satisfactory because the field was fully at field capacity condition. During data collection there representative plot size was taken 33 × 33 cm2 for plant population, 3 m2 for yield and then converted into ha. Depth of seed placement was measured after seed emergence by cutting 10 seedlings at the soil surface. A part of the stem that was inside the soil (from soil surface to seed remnants on the roots) was taken out and its length was measured which is considered as the depth of seed placement. M.C (%) was measured by automatic penetration type moisture meter. Irrigation, fertilizing, weeding and all other intercultural operations were done properly and timely. The crop was harvested on 17 February 2015. Data on yield and yield contributing characters were collected at harvesting stage and analyzed statistically. Mean comparison were adjudged using least significant differences at the 5% level of the probability. Seed Calibration Test Before the field performance test, it was tested in OFRD, ARS, Pabna machinery testing field and seed rate of lentil was calibrated by operating it for 20 m liner distance according to following formula:
W ts = C × WC× RS Where, Wts =Total Weight of seed (gm) which will have to drop through all Lines for 20 m liner distance during PTOS single pass. C = Constant, which valued 2 for 20 m liner distance, WC = Total width of cut (m), RS = Total seed rate (kg/ha)

Achievement/Findings:

The performance of planting methods significantly influence on lentil yield.Mechanical planting methods (IPP and BP) found promising for increasing lentil yield.Mechanical planting can save fuel, land preparation and seeding cost, time, money, human drudgery and can play an important role in maintaining soil health through reduced tillage and can increase cropping intensity by reducing turnaround time. The field efficiency of mechanical planting/seeding was relatively higher than conventional planting/seeding and showed positive relationship with yield trait and yield of lentil. Therefore, at the circumstances of agricultural labor shortage adoption of mechanical planting would be a viable technological option for raising lentil production at the field level.
