Two field experiments were conducted to investigate the effects of three drip irrigation regimes (G1: 120% crop evapotranspiration (ETc), G2: 100% ETc, and G3: 80% ETc) and four nitrogen (N) source treatments (S0: non-fertilized; S1: urea, S2: ammonium nitrate, and S3: ammonium sulfate on water consumption use, water utilization efficiency, chlorophyll, yield and tubers quality of potato (Solanum tuberosum L.; cv Diamond) under a drip irrigation system during two successive winter seasons (2015/16 and 2016/17)). Nitrogen fertilization was applied at 380 kg ha−1 as standard application for potato in the investigated area. The highest tubers yield was obtained from potato grown with G1 S2 (65.8 Mg ha−1), G1 S3 (63.6 Mg ha−1), G2 S2 (64.1 Mg ha−1), and G2 S3 (62.4 Mg ha−1), while the lowest tubers yield was obtained from potato grown with G3 S0 (10.1 Mg ha−1) and G2S0 (17.4 Mg ha−1). Different treatments of N source resulted in a significant increase for water use efficiency (WUtE) compared with unfertilized treatment. For the interaction effect, the highest WUtE was obtained from potato grown with G3 S2 (18.1 kg m−3), followed by G3 S3 (17.6 kg m−3), while the lowest WUtE was obtained from plants grown with G3S0 (3.0 kg m−3). However, the highest chlorophyll content was obtained from plants grown with G1 and any N source, followed by G2S1-3, while the lowest chlorophyll content was obtained from those grown with G3S0. The highest N, S, protein, and P contents in tubers were obtained from plants grown with G3S3, G3S2, and G2S2, while the highest K content in tubers was obtained from plants grown with G1S1 and G1S2. In concussion, the integrative effects of G1 or G2 with S2 or S3 is recommended for high productivity, while the integrative effects of G3S3 and G3S2 are recommended for high quality tubers.

An experiment was conducted in wooden boxes to evaluate water use efficiency, biomass production, nitrogen and potassium uptake and yield of tomato plants (Lycopersicon esculentum) grown under flood irrigation (FI) and surface drip irrigation (SDI). Leaf area, leaf area index, biomass production and yield of tomato plants were significantly (P<0.05) higher in SDI than FI treatment. Biomass production (g/plant) was 53.3 and 42.2 and yield of tomato (kg/plant) was 1.27 and 0.99 in SDI and FI treatments, respectively. Surface drip irrigation increased water use efficiency (Kgm-3) of tomato plants by two fold (37.88) compared to flood irrigation ( 19.88). Significantly (P<0.05) higher concentrations of nitrogen in leaf (3.22%) and stem (2.62 %) were measured for tomato plants grown under SDI than FI (2.63 and 2.19 %). Potassium concentrations on the other hand, showed no significant differences. DOI: http://dx.doi.org/10.3329/jasbs.v38i2.15611 J. Asiat. Soc. Bangladesh, Sci. 38(2): 207-215, December 2012

Plant density affected yield, quality and water use efficiency. Little information describing plant density to optimize yield and quality of potato production is available in the Jordan Valley. This study was aimed to investigate the effects of plant density on the yield and yield components of the potato (Solanum tuberosum L.) cultivar &ldquo;Spunta&rdquo; grown in the middle of the Jordan Valley. Five different densities of plants (41,600 plants ha-1 (D1), 56,000 plants ha-1 (D2), 83,200 plants ha-1 (D3), 28,000 plants ha-1 (D4), and 41,600 plants ha-1 (D5) were randomly distributed over five replicate sites during the growing season from November 2013 to March 2014. Plant height, number of branches, fresh and dry weight of potato plants, tuber number, tuber weight, total yield, specific gravity and water use efficiency of potato plant grown under different plant density were measured. It was found that the productivity of potato increased with increasing plant density, with the highest total, marketable, and non-marketable yields being obtained at densities of 83,200 seeds ha-1, and the lowest occurring at 41,600 seeds ha-1, which equated to total fresh yields of 45.1 and 25.3 tons ha-1, respectively. The highest water use efficiency for marketable yield (11.9 kg m-3) was obtained at a density of 83,200 seeds ha-1, whereas the lowest water use efficiency (7.5 kg m-3) was obtained at a density of 41,600 seeds ha-1. The specific gravity ranged from 1.04 to 1.08 and the average tuber weight ranged from 77.02 g at a density of 83,200 seeds ha-1 to 115.84 g at a density of 28,000 seeds ha-1.
