Abstract/ Executive Summary:

A field experiment was carried out to study the effect of manure and fertilizers on the growth and yield of potato in the village Narayanpur under the Small Scale Water Resource Sector Development Project (SSWRDSP), Local Govt. Engineering Department, Khulna, Bangladesh. Potato was grown with different combination of manures and fertilizers or without combination. The highest plant height was 71.2 cm and lowest was 46.2 cm at 100 days after emergence when potato was grown with cowdung + Mustard Oil Cake (MOC) +N+P₂O₅+K₂O and without manure and fertilizers respectively. However, maximum number of shoot per plant, no. of tuber per hill, yield of tuber per hill, tuber size in diameter were 5.0, 9.0, 365 gm and 14.5 cm respectively when potato was grown with cowdung +MOC+N +P₂O₅ + K₂O as compared to that of other combinations. In addition, the highest yield was 24.3 t ha^-1 and percent infected plant by late blight disease was highest (20) when potato was grown with cowdung+MOC+N+P₂O₅+K₂O and without manures and fertilizers respectively. Whereas, lowest tuber yield was 12.6 t ha^-1 and lowest percent infected plant was 7 in case of without manure and fertilizers and with cowdung +MOC+N +P₂O₅+K₂O, respectively.

Location: Narayanpur village under the area of SSWRDS Project, LGED, Khulna

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Potato

Objectives:

To evaluate the effect of manure and fertilizers on the growth, yield and quality of potato.

Methodology:

The experiment was located in the village Narayanpur under the area of Small Scale Water Resource Sector Development Project (SSWRDS) Project, LGED, Khulna. Total area of land was 435 Sq. m. Individual plot size was 8 x 4.5 Sq. m. The experimental field was 1st opened with a power tiller on the 15th November, 1998. Four ploughing was made to get a good tilth. Weeds and other stubbles were removed from the field carefully. The land was exposed to the natural weathering for 10 days after ploughing. Last ploughing was done at the time of final land preparation. Manure fertilizations were applied at the rate of 10 t ha^-1 cowdung 300 kg Mustard Oil Cake (MOC) 138kgN, 120kg P₂O₅ 130 kg. The experiment was conducted in a Randomized Complete Block Design (RCBD) maintaining three replications were control (T₁) cowdung + mustard oil cake (MOC) (T₂). N + P₂O₅ + K₂O (T₃) and cowdung + MOC+N +P₂O₅+K₂O (T₄). The experimental filed was divided into three blocks. Each block was divided into four plots. Therefore, there was twelve plots in the field. Four treatments were randomly assigned in each block. The border space was 50 cm in all sides. The potato cv. 'Multa' was used in this experiment 20 gm of cut tuber was used as seed. Pit to pit distance was 25 cm and row to row distance was 60 cm. Seeds were treated by formal dehyde to free from disease infection. Seeds were sown at the depth of 2.5cm of the soil. One seed was sown per pit following furrow method. Fifteen Days After Emergence (DAE) 1st earthing up was done and then 30 DAE 2^nd earthing up was done. Irrigation was done three time. Weeding and other intercultural operations were done properly. After 100 DAE the potato tuber was harvested following harmpuling. Recording of data was commenced from 10 DAE. The following parameters were recorded and statistically analyzed. The parameters are plant height, number of shoot per plant, shoot length, number of tuber per hill, size of tuber in diameter and length, tuber yield, number of late blight infected plant.
