Abstract/ Executive Summary:

The inputs usage for MV ant gher than support the hypothesis of under RPG farming is significantly higher than that of MV boro paddy production under YRMV paddy farming in Bangladesh. In other words, be used more efficiently in MV boro paddy production under RPG FP) for MV boro paddy production farming. Moreover, the dev loped by the farmers since mid' 1980s. The cropping pattern has changed the year' round modern variety (YRMV) paddy farming to RPG fa after the introduction of gher farming. The present study aims to estimate the land productivity of MV paddy production under RPG and YRMV paddy ing in southwest Bangladesh. Ninety RPG farmers and 100 YRMV paddy er from two different villages of two different districts interviewed regarding main inputs used and outputs in MV paddy production. The RPG farming has significant impacts on inputs used in MV boro paddy production. The findings of the study indicate that more chemical fertilisers (72%), TSP (61%), MP (94%) and ha MV RPG farming. Similarly, per ha cost of irrigation (61%), pest land preparation (17%) were also higher in MV boro paddy production YRMV paddy farming compared to RPG farming boro paddy production under two farming showed statistically significant difference with each others. Although fewer inputs were being used in MV boro paddy production under RPG farming, per ha yield was statistically high YRMV paddy farming. All the values of the t-statistics such the study. Therefore, it could be concluded that land productivity of MV paddy production inputs can farming than in MV boro and aman paddy production under the YRMV paddy production. The total factor productivity (T was higher in RPG farming compared to YRMV paddy TFP varied widely within the farms between the two farming.

Objectives:

The present study analyses input used in MV boro paddy production under RPG and YRMV paddy farming. Moreover, the present study estimates TFP for MV paddy production between two farming in Bangladesh.

Methodology:

2.1 Farm Survey and Data Collection To assess the impacts of technologically advanced RPG farming on land productivity for modern varieties (MV) of paddy, two contrasting villages. RPG farming Chanchra Village in Jessore District were selected. The Bilpabla Village was selected purposely because the people have vast experience of RPG farming like other parts of Khulna District, and they directly or indirectly depend on their daily livelihood on various gher' farming activities. On the other hand, Chanchra Village located in Jessore District was also purposely selected because the farmers cultivate MV paddy throughout the year. Moreover, Jessore is neighbour of Khulna District. Ninety RPG farmers and 100 YRMV paddy farmers were randomly selected. The farm survey was carried out during November 2007 based on the agricultural cropping year 2007.

2.2.1 Farm land Farmland is the main input for any agricultural crop production. The farmland input was measured in terms of hectare. As usual, about 60 per cent land of total gher farming is used for MV paddy production under RPG 2.2.2 Human labour Human labour includes both male and female labour used in MV paddy production in a crop calendar year. Two types of human labour are used in MV paddy production' hired and family labour. The labour input was calculated in terms of work hours of male and female labour employed for different farm operations. In this study, labour was measured in terms of adult man-days of eight hours. The measurements of hired and family labour are as follows: 2.2.3 Hired labour The existing wage rate of hired labour both for male and female was considered in MV paddy production in RPG farming of Bilpabla Village and YRMV paddy farming of Chanchra Village. As two farming was different in terms of management as well as located in different places, the wage rate was different. The wage rate both for hired male and female was higher in MV paddy production under RPG farming than YRMV paddy farming. 2.2.4 Family labour Both the family supplied male and female labour to be engaged in various activities of paddy production. However, the family-supplied labours were not engaged in full time like hired labours. Moreover, the family' supplied farming. labours work in their paddy fields on a part-time basis. Sometimes, they work farm operation in a day. In addition, sometimes, the supplied labour’s work is equal like hired labour, even plied labour is converted into male labour based on the market price of daily wage of male and female labour in 2007. The opportunity cost paddy farming. Output variable The main output of MV paddy farming was paddy grain considered in terms only 2-3 hours for efficiency of family though, some farmers’ work efficiency is not the same to the hired labour’s. The difference in the efficiency of labour has been taken into account by converting family labour into hired adult man' days. The opportunity cost of family' support of family male and female was varied from Tk.80-110, 50-80, 60-80, 40-60 and Tk.60-90, 40-60, respectively, for MV boro paddy production under RGP farming, MV boro and aman for YRMV paddy farming.

Achievement/Findings:

RPG farming system is an indigenous agricultural technology solely developed by the farmers since mid-1980s. The cropping pattern has changed from YRMV paddy farming to RPG farming after the introduction of gher farming. The RPG farming has significant impact on soil quality on MV paddy production than YRMV farming. The RPG farming has significant impacts on land productivity for MV paddy production than YRMV paddy farming. The findings of the study indicate that more chemical fertilisers such as urea (72%), TSP (61%) MP (94%) and gypsum (88%) used in per ha MV boro paddy production under YRMV paddy farming compared with RPG farming. Similarly, per ha irrigation (61%), pesticides (26%) and land preparation (17%) cost were also higher in MV boro paddy production under YRMV paddy farming compared with RPG farming. Along with main inputs, more hired male labours were also engaged in per ha MV boro paddy production under YRMV paddy farming compared with RPG farming. The total factor productivity for paddy production was higher in RPG farming compared with YRMV paddy farming. The TFP varied widely within the farms between the two farming. Therefore, it could be concluded that RPG farming has increased the land productivity for MV paddy production and reduced input usage as well as costs for per ha MV boro paddy production compared with YRMV paddy production in Bangladesh.
