Abstract/ Executive Summary:

Raipur Upazila is situated in the north-western part of Lakkhipur district. It lies between 22º53´ and 23º04´ north latitude and 90º38´ and 91º50´ east longitude and covers an area of 18,650 ha. It lies in the agro-ecological zones of Lower Meghna River Floodplain (AEZ 17), Young Meghna Estuarine Floodplain (AEZ 18). The upazila comprises of 10 unions and a pourosava having a population of 236,829 (2001). Two land types namely highland and medium highland were identified. The textural classes were sandy loam, loam and clay loam. Five soil groups were identified. Total 55 soil samples were collected and analyzed. It was found that soils of upazila are deficient in N, P, K, Zn and organic matter. Three major cropping patterns were found in the upazila. Fertilizer recommendations for suitable crops are given. Raipur upazila was first surveyed in 1991 and updated in 2008.

Keywords: Raipur upazila, Land types, Soil groups, Cropping patterns,Guide

Location: Raipur Upazila, Lakkhipur

Start Date: 01-01-2007

End Date: 30-04-2008

Program Area: Crop-Soil-Water Management

Commodity: Land management

Objectives:

1. Land and soil resources inventory of Raipur Upazila

2. Soil fertility assessment and fertilizer recommendation.

3. Crop suitability assessment.

4. Preparation of land and soil resource utilization guide with soil and landform map

Methodology:

Field survey was conducted on the basis of semi-detailed soil survey method. Interpretative soil and landform map was prepared using 1:50,000 aerial photographs. Soils were investigated following a catena and composite top soil samples were collected. The sampling frequency were 1 (one) sample per 200 ha, although more samples were taken wherever necessary according to complexity of soils. During survey crops, cropping patterns, soil management data were collected by physical observations and interviewing the farmers. Soil samples were analyzed for fertility assessment. Crop suitability for each land type was determined. Fertilizer recommendations for suitable crops were made. Final soil and landform map was made from the interpretative field map through verification by ground truthing and field checks. After compiling physical and chemical data sets the land and soil resource utilization guide was prepared.

Funding Source:

1. Government

Budget: 150000

Total Budget (Tk.) : 150000

Achievement/Findings:

Major land type recognized was medium highland (53.4%). Major textural classes identified loam (44.6%) and clay loam (11.7%). Major soil groups identified Ramgati (25.0%), Homna (15.6%), and Hatia (8.0%). Suitable crops were rabi vegetables, cabbage, chilli, cauliflower, tomato, potato, rabi maize, watermelon, groundnut, soybean, khesari, mung, lenil, muskali, til, kaon, chhola, zinger, turmeric, onion, garlic, boro rice, T. Aus rice, T. Aman rice, sugarcane, lemon, betelnut. Major cropping patterns were Boro rice-Fallow(F)-T. Aman rice (42.5%) and Rabi crops (soybean/mung/ chilli)-T.Aman rice (7.9%). Fertilizer recommendations for 55 existing and potential crops of the upazila at high and medium yield goals and for 89 crops at high yield goal are given. The soils of upazila are deficient in N, P, K, Zn and organic matter. This guide can be used for determining flood, drought, water-logging and soil erosion. Demonstration site selection for technology transfer can be done with the help of this guide. Upazila land and soil resource's carrying capacity can be estimated which would help in determining food deficit or surplus situation.
