Effect of Mulch and Mustard Oil Cake on Growth and Yield of Potato

MD. ZIAUL HAQ
Department of Horticulture Bangladesh Agricultural University Mymensingh

Abstract/ Executive Summary:

An experiment was conducted to study the effect of different mulching materials and different doses of mustard oil cake (MOC) on the growth and yield of potato (cv. Cardinal) at the Horticulture Farm. Bangladesh Agricultural University. Mymensingh during the period from November, 1999 to February, 2000. There were 4 mulching treatments, viz. flat open, ridge, straw mulch and black pol)1hene mulch and 6 levels of MOC, viz. 0, 1 00, 200, 300, 400 and 500 kg/ha. The experiment -as laid out in RCBD with three replications. Each experimental plot was fertilised with urea, TSP and MP@ 325, 220 and 250 kg per hectare, respectively. No other organic matter was applied, and the experiment was conducted under rain-fed condition. Mulches had significant influence on growth, yield components and yield of potato. The results of the experiment revealed that days required for 80° o emergence of the crop, plant height foliage coverage, weight of tubers per hill and yield of tubers per hectare were high when black polythene mulch was used.

Keywords: Mustard, Oil cake, Growth ,Yield,Potato

Location: At the Horticultural Farm of Bangladesh Agricultural University.

Start Date: 00-11-1999

End Date: 00-02-2000

Program Area: Crop-Soil-Water Management

Commodity: Potato

Objectives:

i) To study the growth and yield of potato with different mulches under rainfed condition

ii) To find out the effect of mustard oil cake on the growth and yield of potato.

Methodology:

The potato seed tubers (cv. Cardinal) were used as planting material, which were supplied by the Bangladesh Agricultural Development Corporation (BADC), Jamalpur. The seed rate was 2 tlha. 3.5 Treatments The experiment consisted of 2 factors: Mulch (A) and mustard oil cake (B). There were 4 levels of mulch and 6 levels of mustard oil cake. Factor A: Mulch i) Flat open (Mo) ii) Ridge (M 1) iii) Straw mulch (M2) iv) Black polythene mulch (M3)The experiment, consisting of 24 treatment combinations was laid out in the randomized complete block design (RCBD) with 3 replications. First of all, the entire experimental plot was divided into three blocks, each of which was then divided into 24 unit plots. The treatment combinations were assigned randomly to the unit plots of each block. The size of a unit plot (bed) was 1.2 m x 3 m. Two adjacent unit plots and blocks were separated by 50 em and 1 m space, respectively.

Achievement/Findings:

The effect of different mulches and various levels of mustard oil cake were found significant on days required for 80% emergence. The plants grown with straw mulch took the longest time to complete 80% emergence, whereas, the plants with black polythene mulch took the shortest time. The height of plant was significantly influenced by different mulches and various levels of mustard oil cake. Plant height was highest with black polythene mulch, and increased with the increased levels of mustard oil cake. The maximum plant height was found in the treatment combination of black polythene mulch and 500 kg MOC/ha, and the minimum plant height was obtained from the treatment combination of ridge method and no MOC application weight of tubers per hill was significantly affected by mulches, and various levels of MOC. The weight of tubers per hill was highest (433.9g) in black polythene mulch, and lowest (218.3g) in ridge method. The weight of tubers per hill increased with increasing levels of MOC. It was highest (362.0 g) with 500 kg MOC/ha and lowest (287.8g) with no MOC. The combination of black polythene mulch and 500 kg MOC/ha gave the highest yield of tubers per hill (452.3g).yield of tubers per plot was significantly influenced by mulches and various levels of MOC. The yield was the highest under the black polythene mulch. The yield per plot was increased with the increasing levels of MOC The yield was the highest under the highest dose of MOC (500 kg/ha). The combination of black polythene mulch and 500 kg MOC/ha gave a yield of 11.0 kg tubers per plot (30.5 t/ha).
