Abstract/ Executive Summary:

Jhenaigati upazila is situated in northern part of Sherpur district lying between 25º04´-25º17´ north latitude and 89º03´-89º08´ east longitude covering 20,839 ha area. It lies in the physiography of Hill areas (Northern and Eastern Hills, AEZ 29), Piedmont plains (Northern and Eastern Piedmont Plains, AEZ 22) and Old Brahmaputra Floodplain (AEZ 9). The upazila comprises of 7 unions having a population of 155,067 (2001). Land types recognized were highland (42.62%), medium highland (38.87%), medium lowland (10.25%) and lowland (1.41%). Textural classes identified sandy loam (6.7%), loam (51.07%), clay loam (32.15%), clay (2.8%). Major soil groups identified were Srimangal, Gazani, Jhenaigati, Nunni, Pritimpasa, Manu, Nalitabari, Sonatala, Silmandi, Ghataail. Hill soils of this Upazila are deficient in N, P, K, S, Zn, Ca and Mg; Piedmont plains are in N, P, K, S, Zn and Mg; and Brahmaputra Floodplain in N, P, K, S, Zn and B. Ten major cropping patterns were found. Fertilizer recommendations for existing and potential crops at high and medium yield goals are given. Addition to location specific fertilizer recommendation this guide can be used for determining crop suitability, site selection of demonstration or trials, determining management area and plan against flood, drought, water-logging and soil erosion.

Keywords: Jhenaigati Upazila, Land types, Soil groups, Cropping patterns,Guide

Location: Jhenaigati Upazila, Sherpur District

Start Date: 01-01-2007

End Date: 30-05-2009

Program Area: Crop-Soil-Water Management

Commodity: Land management

Objectives:

1. Land and soil resources inventory of Jhenaigati 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. Total 140 soil samples were collected and analyzed. Crops, cropping patterns, inundation land types, 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. Jhenaigati was first surveyed in 1990 and updated in 2009.

1. Government

Budget: 120,000

Total Budget (Tk.) : 120,000

Achievement/Findings:

In this upazila, some of the suitable crops identified were rice, wheat, sugarcane, lentil, muskalai, mustard, gram, potato, cauliflower, cabbage, beans, cowpea, lemon, jackfruit, guava, kul, gamar, segun, jam, karoi, chapalish. Major cropping patterns were Natural mixed forest; Annual horticultural crops, Boro rice-Fallow (F)-F; Boro rice-T.Aus rice-T.Aman rice; F-T.Aus-T.Aman and Rabi vegetables-Kharif vegetables. Upazila Guide as a micro-level agricultural planning tool delineates existing soil/land and water resource data bases. It helps plan research activities, set location specific crop trials and demonstration and determine site specific suitable crops and cropping patterns, development of surface and subsurface irrigation network, soil and water conservation measures and drainage system improvement. Use of the guide as a vehicle for agro-technology transfer and diffusion will enable the farmers to apply balanced fertilizer applications, use appropriate soil management technologies and thus increase crop production. The guide can also be used as a data base for other local level development plans such as development of community forestry, fisheries and livestock, re-excavation of canals and construction of embankment, roads, culverts and bridges. There is a good possibility for cultivation of rubber plant in this area.
