Abstract/ Executive Summary:

The field experiment was carried out to find a suitable and economic dose of fertilizer (combination of N, P₂O₅, K₂O and S) for potato cultivation in no tillage with mulch situation. Three fertilizer packages with a control (without fertilizer) were tested. At all locations, the treatment F₄(120, 100, 120 and 20 kg ha^-1) N, P₂O₅. K₂O and S respectively, out yielded the control as well as other fertilizer doses. The tuber yield pattern due to different fertilizer packages followed the same trend for all tested locations but overall performance of Shariatpur was better than Madaripur and Gopalgong. The gross return, gross margin and marginal rate of return were also found to be the highest in the same treatment at all the three locations.

Keywords: No tillage, Saturated soils, Fertilizer packages, Potato production, Tuber yield

Location: Shariatpur, Madaripur and Gopalgong district.

Start Date: 00-11-1996

End Date: 00-03-1997

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Potato

Objectives:

i) To investigate the response of chemical fertilizer on potato under no (zero) tillage condition.

ii) To identify the economic viability of additional uses of fertilizer under that situation.

Methodology:

On-Farm trial was carried out at the farmer's field of Shariatpur sadar upazila of Shariatpur district (L-1). Madaripur sadar upazila of Madaripur district (L-2) and Gopalgong sadar upazila of Gopalgong district (L-3) during the rabi (winter) season of 1996-97 (November 1996 to March 1997). The land type was low with clay loam soil texture. All the areas were under the low Ganges river floodplain soils of Agro-ecological zone (AEZ) 12. The land usually remains fallow during the rabi season (October to March). In the early kharif (mid April to mid May) sprouted seeds of rice (aus and aman at the ratio of 2: 1 respectively) are usually broadcasted and it continues up to the early rabi (October) to harvest aman rice. After that there is no crop in the field up to mid April. This single factor experiment (combination of different fertilizers) was laid out in randomized complete block design (RCBD) with three replications at each location. One farmer was considered as one replication (i.e.. in each location three farmers field was considered for three replications). The fertilizer treatments were viz. F₁ = Control (without any fertilizer), F₂ = 80, 60, 80 and 10kg ha^-1 N, P₂O_5, K₂O and S, F₃ = 100, 80, 100 and 15kg ha^-1 N, P₂O_5, K₂O, S and F₄ = 120, 100, 120 and 20 kg ha^-1 N, P₂O₅, K₂O and S respectively. The sources of N, P₂O₅, K₂O and S were urea, triple super phosphate (TSP), muriate of potash (MP) and gypsum respectively. All fertilizers were applied as basal i.e., the same day of potato tubers sowing. The size of a unit plot was 8 x 6m² (48m²). On an average, 28mm diameter of grade " A" potato tuber (cv. Diamant) were planted following the distances of 60 and 40cm row to row and hill to hill respectively. The tubers were planted on November 11, 12 and 14, 1996 at Shariatpur, Madaripur and Gopalgong respectively. After sowing of tubers all plots have been covered by sun dried water hyacinth (collected previously from the same land) as mulch materials at a height (thickness) of 15cm to retain the soil moisture. All intercultural operations like placement of mulch materials for second time after one month was done equally to harvest better yield from all treatments. Plant height, number of tubers hill^-1, weight of tubers hill^-1 were collected from twenty randomly pre-selected hills of each unit plot. The marketable tuber yield was recorded from three randomly selected spots of (6m²) in each unit plot. The plot yield was converted into hectare yield. The collected data was analyzed statistically for analysis of variance (ANOVA) under RCB design to test for significant differences among treatments. A suitable statistical package MSTAT-C was used for analyzing the data.

Achievement/Findings:

At all locations, the treatment F₄(120, 100, 120 and 20 kg ha^-1) N, P₂O₅. K₂O and S respectively, out yielded the control as well as other fertilizer doses.

The gross return, gross margin and marginal rate of return were also found to be the highest in the same treatment at all the three locations.
