Abstract/ Executive Summary:

The field experiment was carried out at Bangladesh Institute of Nuclear Agriculture, Mymensingh during October 2017 to March 2018, to investigate the effect of different levels of phosphorus and mulches on growth, yield attributes and yield of tomato cv. Roma VF. Two factors: (i) Four levels phosphorus viz., 0, 40, 80 and 120 kg P ha^-1 and (ii) four different mulches viz., no mulch (control), water hyacinth, rice straw and banana leaves. The experiment was laid out in two factors randomized complete block design with four replications. The effect of phosphorus levels and mulches on morphological characters: plant height, leaf number plant^-1, reproductive characters: number of flower clusters plant^-1, flowers plant^-1, days to flowering and yield contributing characters: number of fruits plant^-1, fruit length, single fruit weight and fruit yield both plant^-1 and ha^-1 was significant. The highest morphological and reproductive characters, yield contributing characters and fruit yield (71.98 t ha^-1) were recorded in 120 kg P ha^-1 followed by 80 kg P ha^-1 (69.76 t ha^-1) with same statistical rank. In contrast, the above morphological, reproductive, yield attributes and fruit yield (47.62 t ha^-1) was recorded in control plant where no phosphorus was applied. Application of P @ 80 kg ha^-1 was found suitable dose for tomato cultivation. Among the three mulches, water hyacinth had remarkable effect on plant growth and yield attributes which resulting the highest fruit yield (68.35 t ha^-1) in tomato. So, we may use water hyacinth mulch with application of 80 kg P for maximizing tomato fruit yield during winter season for silty loam soil.

Keywords: Tomato, Phosphorus, Mulching, Yield, Fertilizer

Location: Research Farm of the Bangladesh Institute of Nuclear Agriculture, Mymensingh

Start Date: 00-10-2017

End Date: 00-03-2018

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer, Tomato

Objectives:

To assess the optimum level of phosphorus and to determine suitable mulch for maximum production of tomato.

Methodology:

The field experiment was carried out at the Research Farm of the Bangladesh Institute of Nuclear Agriculture, Mymensingh during the period from October 2017 to March 2018. The selected site was a medium high land and the pH of the soil was 6.4 with organic matter content of 1.21%. The analytical data of the soil sample from the experimental area was organic matter 1.67%, N 0.09%, available P 4.81ppm, exchangeable K 0.27 me/100 g and available S 13.9 ppm. The tomato variety Roma-VF was used as planting material in the experiment. The experiment consisted of two factors: Factor A: Four different levels of phosphorus such as 0, 40, 80 and 120 kg ha^-1 and Factor B: three mulches such as water hyacinth, rice straw and banana leaves. The experiment was laid out in two factors randomized complete block design with four replications. Seeds were sown in seedbed on 29 October 2017 and 27-day old seedlings were transplanted in the experimental field with recommended spacing of 50 cm × 50 cm. The unit plot size was 4 m × 3 m. Urea, muriate of potash (MoP), gypsum and cow dung were applied at the rate of 280 kg ha^-1, 180 kg ha^-1, 80 kg ha^-1 and 10000 kg ha^-1, respectively (BARC, 2012). The triple superphosphate (TSP) was applied according to treatment. Whole amount of TSP, gypsum and half of MoP were applied as basal dose during final land preparation, cow dung also applied before 10 days of final land preparation. The remaining half of MoP was applied as top dressing at 45 days after transplanting (DAT). Half of urea was applied as top dress at 21 DAT and remaining half was applied at 45 DAT. Weeding, pruning, staking, pesticides spray and other intercultural operations were done when required.The first trip irrigation was given 30 days after planting (DAP) followed by irrigation at 45 DAT. Mulching was also done after second irrigation at appropriate time by breaking the soil crust. At harvest, ten plants from each plot were selected randomly for data recording on morphological and reproductive characters, yield and yield related traits. Fruit yield was collected from each plot excluding border line and converted into t ha^-1. Harvesting was done at different dates depending on fruit ripening. The collected data were analyzed statistically following the analysis of variance (ANOVA) technique and the mean differences among treatments were compared by Duncan’s Multiple Range Test (DMRT) using the statistical computer package program, MSTAT-C (Russell, 1986).

Achievement/Findings:

Tomato growth and yield were affected by different levels of phosphorus application and use of mulches. Application of P @ 80 kg ha^-1 was found suitable dose for tomato cultivation. Among the three mulches, water hyacinth had remarkable effect on plant growth and yield attributes which resulting the highest fruit yield in tomato. So, we may use water hyacinth mulch with application of 80 kg P for maximizing tomato fruit yield during winter season for silty loam soil.
