Abstract/ Executive Summary:

Field experiments were conducted to study the changes in dry matter production and to determine the total nutrient uptake of groundnut as influenced by poultry manure in combination with chemical fertilizers. BARI Chinabadam-6 was sown on December 2-6, 2007 in Lalmonirhat, Burirhat and Dinajpur farmers’ field. Six treatment combinations comprising two levels of each of N (20 and 60 kg ha^-1), P ( 30 and 45 kg ha^-1) and three levels of poultry manure (0, 2 and 4 t ha^-1) along with one control treatment were tested in a randomized complete block design with three replications. A blanket dose of 20 kg S, 50 kg K, 2 kg Zn and 1 kg B ha^-1 was used in each treatment and also to develop these practices in the farmer’s field of Burirhat, Lalmonirhat and Dinajpur. Poultry manure along with chemical fertilizers had significant influence on pod yield of groundnut in the study areas. Significantly higher pod yield Burirhat 2.94 t ha-1, Lalmonirhat 2.79 t ha-1 and Dinajpur 2.91 t ha-1 was produced with 4 t ha^-1poultry manure along with 45 kg P and 20 kg N ha^-1. Therefore, 4 t PM ha^-1 in combination of N20P45 kg ha^-1 along with the blanket dose S20K50Zn2B1 kg ha^-1 would be most suitable for the cultivation of groundnut in Northern region of Bangladesh (AEZ-3).

Keywords: Groundnut, Poultry Manure, Chemical Fertilizers

Location: Lalmonirhat, Burirhat and Dinajpur

Start Date:

End Date: 30-06-2008

Program Area: Crop-Soil-Water Management

Commodity: Ground nut

Objectives:

i. To investigate the yield potentiality of groundnut ii. To study the influence on dry matter production and iii. To determine the nutrient uptake as influenced by poultry manure in combination with chemical fertilizers

Methodology:

The experiment was carried out in the farmer’s field of Lalmonirhat and Dinajpur and at the Agricultural Research Station (ARS) farm, Burirhat (AEZ-3). The design of the experiments was RCBD . BARI Chinabadam-6 was sown on December 2, 3 and 6, 2007 in Dinajpur, Burirhat and Lalmonirhat respectively. Unit plot size was 3m X 2.4m. Seeds were sown with a spacing of 30 cm between rows and 15 cm within a row. Two to three seeds were sown per hill and plants were thinned out to one plant per hill after establishment. Hand weeding was done twice during the growing season. There were six treatments replicated three times. The initial soil samples were collected from the respective fields and were analyzed in the Soil Science Laboratory, BARI. Accordingly, the fertilizer doses and treatments were re-adjusted and based on theses, treatments were as follows: T1- N20P30 kg ha^-1 + PM0 t ha^-1 T2- N20P30 kg ha^-1 + PM2 t ha^-1T3- N20P30 kg ha^-1 + PM4 t ha^-1 T4- N60P30 kg ha^-1 + PM4 t ha^-1 T5- N20P45 kg ha^-1 + PM4 t ha^-1 T6- Absolute control Nitrogen and phosphorus were used in the form of urea and TSP. All the treatments except the control, also received 20 kg sulphur (S), 50 kg K, 2 kg zinc (Zn) and 1 kg boron (B) ha^-1, in the form of gypsum, muriate of potash, zinc sulphate and boric acid, respectively. All the fertilizers were incorporated in the soil during the final land preparation. A general application of lime (Dolomite) was applied @ 2 t ha^-1one month before final land preparation in Burirhat and Lalmonirhat to raise the soil pH for the availability of major plant nutrients. Data collected on plant height, number of plants m-2, number of branches plant^-1, number of pods plant^-1, number of kernels pod^-1, 100 pod and kernel weight and pod yield were done. Collected data were statistically analyzed and means of treatments were compared by DMRT. Ten randomly plants were carefully uprooted from each plot at harvest. The plants were first air dried, then oven dried at 70º C for nutrient analysis.

Achievement/Findings:

Six treatment combinations comprising two levels of each of N (20 and 60 kg ha^-1), P ( 30 and 45 kg ha^-1) and three levels of poultry manure (0, 2 and 4 t ha^-1) along with one control treatment were tested in a randomized complete block design with three replications. A blanket dose of 20 kg S, 50 kg K, 2 kg Zn and 1 kg B ha^-1 was used in each treatment and also to develop these practices in the farmer’s field of Burirhat, Lalmonirhat and Dinajpur. Poultry manure along with chemical fertilizers had significant influence on pod yield of groundnut in the study areas. Significantly higher pod yield Burirhat 2.94 t ha^-1, Lalmonirhat 2.79 t ha^-1 and Dinajpur 2.91 t ha^-1 was produced with 4 t ha^-1poultry manure along with 45 kg P and 20 kg N ha^-1. Therefore, 4 t PM ha^-1in combination of N20P45 kg ha^-1 along with the blanket dose S20K50Zn2B1 kg ha^-1 would be most suitable for the cultivation of groundnut in Northern region of Bangladesh (AEZ-3).
