“…The application of high concentration of nitrogen fertilizer can improve the water status and nutrient absorption of plants under salinity stress and improves the yield in subtropical conditions (Kabir et al, 2005). Root dry weight of Vigna radiata L. Wilczek increased with the combined application of N and K fertilizers in Bangladesh under saline stress and waterlogged conditions (Amin et al, 2015). Naeem et al (2006) showed that inorganic fertilizers (NPK; 25-50-50 kg ha −1 ) positively affected mungbean yield in Pakistan.…”

A field experiment was conducted comprising two varieties of mungbean, BARI Mung-5 (V1) and BARI Mung-6 (V2), and five levels of phosphorus fertilizer: triple super phosphate [Ca(H2PO4)] viz. T1 (control), T2 (42.5 kg P ha−1), T3 (85 kg P ha−1), T4 (127.5 kg P ha−1), and T5 (170 kg P ha−1). The experiment was organized in a randomized complete block design with three replications. V1 produced the highest number of pods per plant (7.65), whereas the maximum 1,000-seed weight (49 g) was produced by V2. The maximum plant height (30.89 cm), number of branches per plant (8.55), number of leaves per plant (19.05), number of pods per plant (10.25), pod length (8.95 cm), number of seeds per pod (9.11), 1,000-seed weight (48.17 g), and yield (1.05 t ha−1) were obtained from the T4 treatment. The interaction of phosphorus levels and varieties had a considerable effect on the growth, yield, and yield attributes of mungbean. The highest number of leaves (20.44) and number of pods (10.39) were obtained from V1 when 127.5 kg P ha−1 (T4) was applied, whereas the maximum number of seeds per pod (9.25) and maximum pod length (9.09 cm) were obtained when 85 kg P ha−1 and 42.5 kg P ha−1, respectively, were used. The highest number of branches per plant (8.87), 1,000-seed weight (52.83 g), and the maximum seed yield (1.14 t ha−1) were achieved from the treatment V2T4 owing to the interactive effect of phosphorus dose and mungbean variety.

“…However, maturity duration delayed for medium N dose (N 2 ). Amin et al (2015) reported that soil waterlogging delayed flowering but the application of N and K fertilizers after the termination of waterlogging enhanced early flowering by 4 to 6 days compared to that of control.…”

Post-waterlogging Rescue Nitrogen Improves Waterlogging Tolerance in Mungbean (Vigna radiata)

The study was conducted at the Stress Research Site of the Department of Agronomy of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during the period from April to July 2017 to evaluate the effect of rescue nitrogen fertilizer for improving the performance of waterlogging tolerance in mungbean genotype VC-6173A. Both waterlogged and non-waterlogged mungbean plants were received varying doses of rescue nitrogen from urea fertilizer. The rescue nitrogen (N) treatments were: N0-no rescue N; N30 - 20 and 10 kg ha-1 rescue N applied at 0-day and 15-day after removal of waterlogging (ARW); N40 - 30 and 10 kg ha-1 rescue N applied at 0-day and 15-day ARW and N50 - 40 and 10 kg ha-1 rescue N applied at 0-day and 15-day ARW. The study was laid out in a randomized complete block design with four replications. Different levels of rescue N improved plant height, leaf chlorophyll index, phonological period, plant growth, pod formation and seed yield of mungbean. N-treated plants showed higher relative SPAD chlorophyll values and the increment was higher for higher N-dose. Waterlogging reduced 40% root dry matter and 34% both shoot and total dry matter relative to non-waterlogged plants. Rescue N significantly increased both the root and shoot dry matter. The waterlogged plants without rescue N showed 29% reduction in the number of pods per plant and the reduction showed 13% for rescue N40 in waterlogged plants. The seed yield reduction was 25% in waterlogged plants without rescue N but with rescue N, seed yield remarkably increased particularly in N40-treated plants. Therefore, the study suggests that rescue N fertilizer application may be a viable practice in improving waterlogging tolerance and increasing yield of mungbean.

“…Mineral nutrients are important for plant root growth (Fageria and Moreira, 2011). Amin et al (2015) stated that Potassium supplement improves root and shoot growth and enhance plant nutrient uptake. Phosphorus and iron increase plant root length (Ding et al, 2018).…”

Purpose : Fruit peels waste is one of the waste accumulate in huge quantity every day. It is a serious problem and need to be managed to make environment free from pollution. Fruit peels are very rich in macro and micro nutrients that are beneficial for plant growth. By using fruit peel as fertilizer we can reduce load of wastes and can get more benefits than inorganic fertilizer. Research Method : The experiment was carried out in a Completely Randomized Design with six treatments having twenty replicates. Treatments were, recommended fertilizer application at basal and topdressing (T1, control), half dose of recommended fertilizer application at basal and topdressing times with 1g of banana peel powder (T2), 1g of pomegranate peel powder (T3), 1g of orange peel powder (T4), 0.5g each of banana and pomegranate peel powders (T5) and 0.5g each of orange and banana peel powders (T6) at both times. All agronomic practices were followed as per Department of Agriculture, Sri Lanka except fertilizers. Findings : The results reveals that application of fruit peel powder at basal and top dressing had significant differences (P<0.05) on plant height, number of leaves per plant, leaf area, chlorophyll content, days to 50% and 100% flowering, dry weights of leaves, stem, root and fruit, fruit length and girth. At 1st, 2nd, 3rd and 4th picking, and the highest value was obtained in T6 and lowest value in T1. Originality/ Value : Application of fruit peel powder into the soil leads to improve growth and yield of okra in sandy regosol compared to recommended inorganic fertilizer and present study suggested that, among the all tested treatments, half recommended fertilizer application at basal and topdressing times with 0.5g each of orange and banana peel powders at both times would be the most suitable fruit peel powders to get higher growth and yield of okra in sandy regosol.
