Abstract/ Executive Summary:

In an experiment conducted at the Regional Agricultural Research Station. BARI. Ishurdi, the IITA-IRRI designed "Rolling Injection Planter" was evaluated against "hand dibbling" for the establishment of maize (cv. Barnali) at no-tillage following the harvest of wetland rice (T.aman) in calcareous dark gray floodplain medium highland soil. The field performance of the planter was encouraging under the given field conditions i.e, 29.31 % moisture and 1.69 g/cm² bulk density up to 15 cm depth. The draft requirement ranged from 8 to 16 kg. At the working speed of 2.8 km/h the machine had a "field capacity" of 0.057 ha/h and" field efficiency" of 76%. The seed covering device of the machine, however. however did not work satisfactorily. The grain yield of maize was not affected significantly by the methods of planting. Machine planting saved labour and required only 32 man-h/ha against 43 in hand planting.

Keywords: IITA-IRRI designed " Rolling injection planter", Establishment, Wetland rice

Location: Regional Agricultural Research Station. BARI. Ishurdi

Start Date: 00-00-1986

End Date: 00-00-1987

Program Area: Farm Mechanization

Non-commodity: Performance

Objectives:

This study was aimed at evaluating the efficiency of manually operated lITA-IRRI designed "Rolling Injection Planter" in comparison to "hand dibbling" for the establishment of maize following the harvest of T. aman rice in dark grey calcarious floodplain medium highland soil.

Methodology:

A single row "Rolling Injection Planter" obtained from IRRI through its Farming Systems Programme, was tested in the laboratory as well as in the field for the establishment of maize following the harvest of T.aman rice. In the laboratory test, the equipment was calibrated for the test crop, maize, for standardization of metering mechanism, i.e., seed delivery rate and seed breakage. In calibration, dropping of 2 seeds per hill was taken as optimum considering standard seeding practice to ensure normal plant population of the crop. The field experiment was conducted at the Regional Agricultural Research Station, BARI, Ishurdi during the winter season of 1986-87. Maize was planted under no-tillage condition immediately after T. aman (cv. BR3) harvest. Two treatments i.e, (i) seeding by the planter, and (ii) seeding by hand (dibbling) were laid out in randomized complete block design and replicated three times. The unit plot dimension was 15 m x 15 m. The crop was fertilized with 80-60-40 N, P₂O₅ and K₂O kg/ha. Data on missing hills, seeds dropped per hill, hill and row spacings, depth of seeding, power requirement at working speed (for the planter), field efficiency, field capacity, and soil bulk density were collected at the time of seeding. Comparative statement of cost in machine and hand seeding were made by measuring the working accuracy and labour requirements.
