Abstract/ Executive Summary:

To study the effect of mulching and fertilizer management practices on the growth and yield of garlic, an experiment was conducted using three kinds of mulches viz., black polyethylene, straw and water-hyacinth with a control and three types of fertilizer management practices viz., cow dung (F1), urea + TSP + MP (F2) and urea + TSP + MP + cow dung (F3) and compared with no fertilizer/manure. The experiment was conducted at Dinajpur from November 2005 to March 2006. Plants grown under black polyethylene, water hyacinth and straw mulches were produced the yields of 5.80, 5.70 and 5.48 t ha^-1, respectively which were 39, 36.6 and 31.41% higher than the control (4.17 t ha^-1). The effect of black polyethylene and water hyacinth mulch were almost similar on the growth and yield of garlic. On the other hand, the crops grown with urea + TSP + MP and urea + TSP + MP + cow dung and only cow dung gave yields of 6.36, 6.03 and 5.23 t ha^-1, respectively which showed about 80.68, 71.30 and 48.57% increase over the control (3.52 t ha^-1). The interaction effects of mulching and fertilizers did not exhibit significant variations. Though the application of black polyethylene mulch is somewhat hazardous, if it is possible to use the water hyacinth and black polyethylene mulch along with F2 and F3 were suitable for increasing production.

Program Area: Crop-Soil-Water Management

Commodity: Garlic

Objectives:

To study the effect of different mulches and fertilizer management practices on the growth and yield of garlic.

Methodology:

The field experiment was conducted by the Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during the period from November 2005 to March 2006 to study the effect of mulches and different organic and inorganic fertilizer doses on the growth and yield of garlic.The soil of the plot was silt loam in texture having pH 5.8, total N, available P and K were 0.05%, 20 ppm and 0.18 me per 100 g of soil, respectively. Four treatments of mulches denoted as no mulch as control (M0), black polyethylene mulch (M1), straw mulch (M2) and water hyacinth (M3). Fertilizer treatment control (F0), cow dung (F1), urea + TSP + MP (F2) and cow dung + urea + TSP + MP (F3) as shown in this study. The factorial experiment was laid out in a randomized complete block design with three replications. The whole field was divided into three blocks each containing 16 plots. The plot size was 1x0.9 m. The space between the blocks and plots were 50 and 30 cm, respectively. The 16 treatment combinations were assigned randomly to the unit plot of each block so as to allot one treatment combination only once in each block. Planting of a local garlic was done by placing cloves at a depth of 2 cm in the soil with the use of a pointed stick. The spacing was 22 x 15 cm. Planting was done on November 10, 2005. Ten days before the clove planting, the entire quantity of well decomposed cow dung, TSP and MP were applied in the unit plot as per treatment and thoroughly mixed with the soil. Mulching was done immediately after planting with water hyacinth and fresh rice straw. Black polyethylene sheet with small holes at proper spacing was spread over the plot and then the cloves were placed in soil at the required depth. Ten plants were selected randomly from each unit plot for the collection of data. Weeding were done throughout the growth period. After attaining maturity, garlic was harvested. The data on different yield components were statistically analyzed and were evaluated by LSD test.

Achievement/Findings:

The mulches used in the investigation showed better performance than the control on yield and yield contributing characters of garlic. Among the treatments of fertilizer management practices, urea + TSP + MP and cow dung + urea + TSP + MP showed more or less similar performance on yield and contributing characters.
