Abstract/ Executive Summary:

The study was conducted at the BRRI Research Farm, Joydebpur, Gazipur during Aus, Aman and Boro seasons, 1989 on a previously cultivated, clay loam soil to determine the time required and cost involved for land preparation for the cultivation of wetland rice field with tractor, power tiller, country plough and spade. Four land preparation methods: i) two ploughing with tractor + one laddering, ii) two ploughing with power tiller + two laddering, iii) Three ploughing with country plough + three laddering and iv) two spading + two laddering formed treatment variables. Laddering was done through traditional method (i.e., by pulling the ladder over the cultivated land by bullock). Results revealed that ploughing with tractor required the minimum number of human laborer (153 man-day/ha) which was significant different from other treatments. Land preparation with spade required the highest man-days (18.74) followed by ploughing by country plough (7.26). Although the method of laddering was same for all the treatments, degree of cultivation by different implements caused variation in time required for laddering. Labor required for laddering varied from 0.45 to 1.33 man-days across the treatments. The trend, however, followed the same order as that of ploughing. Almost a similar trend was observed in the case of animal labor required for laddering. Tillage by country plough only required animal power while it was not necessary for the tillage by tractor and power tiller. The cost of different tillage operations was shown that land preparation by country plough entailed the minimum cost while the maximum cost was involved in land preparation by tractor and spading, the difference in cost was however, more than double. Although, the cost of spading was among the treatments but most of the cost was for human labor. Most farmers in Bangladseh utilize surplus family labor in the production practices. Therefore, those farmers who don’t employ hired laborers and have not sufficient cash for mechanized custom tillage may adopt for land preparation by spade. On the other hand, in order to avoid labor crisis in the peak season and to minimize turn-around time, medium farmers may adopt power tiller.

Location: BRRI Farm, Gazipur

Start Date: 30-03-1989

End Date: 31-12-1989

Program Area: Socio-economic and Policy

Commodity: Rice

Objectives:

To determine the time required and cost involved for land preparation for the cultivation of wetland rice with different implements

Methodology:

The study was conducted at the BRRI Research Farm, Joydebpur, Gazipur during Aus, Aman and Boro seasons, 1989 on a previously cultivated , clay loam soil to determine the time required and cost involved for land preparation for the cultivation of wetland rice field with tractor, power tiller, country plough and spade. Four land preparation methods: i) two ploughing with tractor + one laddering, ii) two ploughing with power tiller + two laddering, iii) Three ploughing with country plough + three laddering and iv) two spading + two laddering formed treatment variables. Laddering was done through traditional method (i.e., by pulling the ladder over the cultivated land by bullock). Randomized complete block design with three replications was used. The size of each plot was 25 m x 40 m. Total time required for each of the treatment was recorded. Three seasons' data were recorded and converted into hours per hectare. The time required for human labor and animal labor were converted into man-day and animal days per hectare, respectively.The cost was calculated from the prevailing wage rate of labor., driver, animal and the rent of machinery. The rent for tractor, power tiller, country plough and spade were Tk. 15.00, Tk. 5000, Tk. 0.50 and Tk. 0.25 per hour, respectively. The cost of diesel was Tk. 7.47 per liter. The wages of tractor driver , power tiller driver, human labor and animal labor were Tk. 50.00, Tk. 43.00, Tk. 34.00, and Tk. 30.00 per day, respectively.

The cost of different tillage operations was shown that land preparation by country plough entailed the minimum cost while the maximum cost was involved in land preparation by tractor and spading, the difference in cost was however, more than double. Although, the cost of spading was among the treatments but most of the cost was for human labor. Most farmers in Bangladesh utilize surplus family labor in the production practices.
