Abstract/ Executive Summary:

The experiment was carried out at the research field of Agronomy Division, BARI, Joydebpur, Gazipur during rabi season of 2013-14 to compare the performance of tillage implements for preparing the land for wheat cultivation in getting higher yield. Four types of tillage implements viz. High speed rotary tiller (one pass), Inclined plate seeder (tillage cum seeder, one pass), Bed planter (two pass) and Traditional power tiller (three pass) were used as treatments variables. Different tillage implements had significant effect on bulk density and ploughing depth. The highest bulk density (1.04 g/cc) was recorded where land was prepared by traditional power tiller but statistically identical bulk densities (0.86-0.90 g/cc) were observed in other cases. Higher depth of ploughing was observed in bed planter (9.84 cm) and high speed rotary tiller (9.16 cm). The maximum number of spikes/m² (170.1) was obtained from high speed rotary tiller but in other cases, identical number of spikes/m² was observed. The highest grain yield was obtained from high speed rotary tiller (3.70 t/ha) which was similar to inclined plate seeder (3.22 t/ha) and bed planter (3.16). The minimum grain yield (3.06 t/ha) was found in traditional power tiller. Based on two years study, it might be concluded that high speed rotary tiller might be better for wheat cultivation considering turn around period, easiness and grain yield.

Commodity: Performance evaluation

Objectives:

To compare the performance of tillage implements for preparing the land for wheat cultivation in getting higher yield with minimum cost.

Methodology:

The experiment was carried out at the research field of Agronomy Division, BARI, Joydebpur, Gazipur during rabi season of 2012-13. The soil of the experimental field was silty caly loam in texture with pH 5.8 belonging to Chhiata series under AEZ 28. Four implements viz. High speed rotary tiller (one pass), Inclined plate seeder (tillage cum seeder, one pass), Bed planter (one pass) and Traditional power tiller (three pass) were tested in wheat cultivation. The experimental field was divided into four blocks of 20 m x 30 m leaving 2 m space between blocks. Each block was prepared by a particular implement and wheat was sown. After sowing, each block was divided in to three unit plots of 9 m x 20 m leaving 1.5 m space between two unit plots. Thus, each implement was replicated by trice. Therefore, data were analyzed following randomized complete block design with three replications. Fertilizers were applied @ 120-30-90-15-3-1 kg/ha of NPKSZnB. Half of N and full amount of other fertilizers in the form of urea, triple super phosphate and muriate of potash, gypsum, zinc sulphate and boric acid were applied as basal. Prodip variety of wheat was sown on 19 November 2013 with 20 cm solid line. Soil samples for measuring bulk density were collected from 3 points in each plot. Flood irrigation was given after sowing for proper emergence of the crops The remaining ½ N was top dressed at 20 days after sowing (DAP) followed by irrigation. Irrigation and other intercultural operations were done as and when necessary.
