Influence of root-knot nematode, Meloidogyne incognita (Kofoid & White) Chitwood infection on different plant growth parameters in Mungbean, Vigna radiata (L.) Wilczek

Root-knot nematode, Meloidogyne incognita (Kofoid & White) Chitwood, is a major threat to mungbean cultivation. The pest causes a significant reduction in plant growth parameters that ultimately results in loss of grain yield. The present study was carried out under glass house condition to study the effect of different inoculum load of root-knot nematode M. incognita on plant growth, nodulation and nematode development and nutrients status of Mungbean. The results revealed a progressive decline in plant growth parameters viz., fresh and dry shoot weight and shoot length with respect to increase in inoculum level. However, fresh and dry root weight showed the opposite trend. The fresh and dry shoot weight was decreased by 44% and 66%, respectively at 4 J2s/g soil. The chlorophyll content in the leaves also decreased with the increase of inoculum level from 100-6000 J2s/pot. Nutrients contents of the plant viz. N, P, K, Ca and Mg were significantly reduced in shoots while in roots these was increased with an increase of inoculum levels. Nodulation was affected by 80% at the highest inoculum level i.e. 6000 J2s/pot. Also leghaemoglobin, bacteroid content and nitrogenase activity was reduced progressively with increased levels of nematode inoculum. Thus, the root-knot nematode, M. incognita interferes with the process of symbiotic nitrogen fixation between mungbean host and rhizobium and that can affect the quality of produce.

Variation of Epiphytic Flora Affecting Silage Quality in Pure and Mixed Mung Bean and Sweet Sorghum

This study was carried out to determine the microorganism population affecting silage quality of sweet sorghum and mung bean cultivated with different sowing patterns as mixture or sole crop. Twin row (20×55 cm row spacing), narrow row (55 cm row spacing) and conventional row (75 cm row spacing) were used as mixture sowing patterns. The mixtures were formed based on the plant densities and alternative row numbers of sweet sorghum and mung bean. Sowing was made on alternation rows of 1 row mung bean plus 1 row sweet sorghum (R1:1) and 1 row mung bean plus 2 rows sweet sorghum (R1:2). In pure and mixed cultivations, the plant density of sorghum was 14 plants m-2 while the plant densities of mung bean were 14, 21 and 28 plants m-2. The experiment was planned as two-factors (sowing patterns and mixtures) and was arranged in randomized blocks according to the split plot design with 3 replications. Pure and mixed plants were harvested when the sweet sorghum plant reached the dough stage. Lactic acid bacteria, enterobacteria and yeast and mold populations in the plant epiphytic flora were investigated under experimental factors. There were significant effects of the main factors and their interactions on the plant epiphytic microorganisms. According to the results obtained from the current study, mixed cultivation of sweet sorghum and mung bean in conventional row pattern improved the desired lactic acid bacteria population for silage quality, while reducing the undesirable enterobacteria and yeast and mold population for silage quality. It was determined that the (R1:2) MB14+SS14 mixed cultivation system was the most suitable mixture in conventional row pattern in terms of high lactic acid bacteria population.

Increasing Productivity and Profitability of Summer Mungbean through Cluster Frontline Demonstrations in Sonipat, Haryana

Background: Cluster frontline demonstrations on summer mungbean were conducted at farmers’ fields in 2018-19 and 2019-20 in Sonipat district of Haryana state. Crop yield and returns of demonstrations were compared to those obtained in the local check plots. Adoption of improved practices of crop production in demonstration plots increased the crop yield by 30% over local check. Methods: A total number of 150 cluster front line demonstrations (CFLDs) were conducted in 60 ha. area during 2019 and 2020. A survey to get information on summer mungbean cultivation practices was undertaken before conducting the demonstrations. Selection of farmers and improved practices for demonstrations were done on the basis of survey information. Result: The average yield recorded in the demonstration and local check plots was 580 kg/ha and 447 kg/ha, respectively. This increase in yield was recorded with additional expenditure of Rs. 2285/ha. Net returns, additional returns and benefit cost ratio in demonstrations came out to be Rs. 13076 /ha, 3073 /ha and 1.77, respectively. The extension and technology gaps were recorded as 132.5 and 920.0 kg/ha, respectively. The technology index of 61.3% strongly indicated the technology inadequacies in the crop cultivation. The results of demonstrations revealed that low level of productivity at farmers’ fields could be increased to sustainable level by adoption of improved practices.

Replacement of Synthetic Nitrogenous Fertilizer by Human Hair Hydrolysates in Cultivation of Mung Bean (Vigna radiata L.)

Comparative Effect of Inoculation of Phosphorus-Solubilizing Bacteria and Phosphorus as Sustainable Fertilizer on Yield and Quality of Mung Bean (Vigna radiata L.).

Globally, the availability of phosphorus (P) to crops remains limited in two-thirds of the soils, which makes it less accessible to plants and ultimately associated with low crop yields. The present study investigated the effect of phosphorus-solubilizing bacteria (PSB; Pseudomonas spp.) for the improvement of phosphorus in mung bean (Vigna radiata) varieties and growth of net grain and biological yields. Results showed that inoculation of mung bean varieties with PSB at the rate of 100 g/kg seed significantly improved the root and shoot dry weight of about 1.13 and 12.66 g, root and shoot length of 14.49 and 50.63 cm, root and shoot phosphorus content of 2629.39 and 4138.91 mg/kg, a biological yield of 9844.41 kg/ha, number of pods of 17 per plant, number of grains of 9 per pod, grain yield of 882.23 kg/ha, and 1000-grain weight of 46.18 g after 60 days of observation. It was also observed that PSB-treated varieties of mung bean showed the maximum photosynthetic yield, photosynthetic active radiation, electron transport rate, and momentary fluorescent rate of 0.75, 364.32, 96.12, and 365.33 μmol/m2 s, respectively. The highest harvest index of 13.28% was recorded by P-treated mung beans. Results disclosed that inoculation of seeds of mung bean with PSB exhibited different effects in measured parameters. It is concluded that PSB possessed remarkable results in measured parameters compared to the control and highlighted that PSB could be an effective natural sustainable fertilizer for mung bean cultivation in sandy soil.

Ecogeographic assessment of mung bean (Vigna radiata (L.) R. Wilczek) from the collection of the Vavilov Institute (VIR)

Background.Mung bean (Vigna radiata(L.) R. Wilczek) is a nontraditional crop for Russia. The crop’s main areas of cultivation are situated in the subtropical zone of the planet. However, positive experience with mung bean cultivation in a number of regions – the South of the European part and the Far East of Russia – implies the expediency of a search for source materials suitable for the development of cultivars adapted to these conditions.Materials and methods.The results of the field phenotyping of 76 mung bean landraces from VIR have been analyzed. The experiments were performed in 1949–1956 in Uzbekistan (former Central Asian Branch of VIR), and in 2009, 2018 and 2019 in Astrakhan Province, where VIR’s collection had been reproduced from the early 1990s. The data on the variability of phenological and agronomic characters and their relationships were compared for both areas and analyzed using the methods of multidimensional statistics.Results and discussion.A strong variability of all studied characters and their dependence on the environment were observed in both locations. According to the averaged longterm data, differences were found in the duration of interphase periods and the entire growing season, seed yield, plant height, and 1000 seed weight in both sites. Significant differences were shown in the strength of correlations between the studied characters. In Astrakhan Province and in the years with less favorable conditions in Uzbekistan, the level of correlations between most traits was higher. Therefore, an increase in the strength of the relationships between crop characters may be regarded as an indicator of unfavorable growing conditions. The genotypes with short periods from sprouting to flowering and from sprouting to maturation were the most resistant to environmental changes. It is these traits that should first of all be transferred to mung bean cultivars when promoting its production to the north, beyond its traditional area.

The effect of dung and local microorganism of banana corm application on the growth and the yield of mung beans (Vigna radiata L) Vima - 2 variety

Mung beans are plants that have high economic value but the production of mung beans in Indonesia is still low. Dung serves to provide nutrients for plants, improve soil structure, and retain water in the soil. MOL (local microorganisms) banana corm has a number of microorganisms that can help plants absorb nutrients found in the soil. The purpose of this study was to determine the effect of the interaction between types of dung (dung) and banana corm local micro organization (MOL) on the growth and yield of mung beans Vima 2 and to determine the type of dung and the MOL dose of banana corm that was best for the growth and yield of mung bean plants. The method used in this study was a randomized block design with 2 factors and 3 replications. The first factor is the type of dung = no dung (j0), chicken dung (dung) (jl), goat dung (j2) and cow dung (j3). The second factor was the MOL dose of banana weevil, 0 ml plant-1 (m0), 50 ml plant-1 (m1) and 100 ml plant-1 (m2). The results showed that the application of dung and the MOL dose of banana corm did not show any interaction, but there was an independent influence by the type of dung on the parameters of plant height, number of pods per plant, number of seeds per plant, weight of seeds planted, and harvest index, so that the type of dung that gives optimum results in mung bean cultivation is chicken dung.

The research was carried out as a pot in an open field (June 16 - July 24) at Isparta University of Applied Sciences, Faculty of Agriculture experiments area in 2020. In the study, Partow variety as a large seed, 70 E 07 genotype as a medium size and 70 S 07 genotype as a small seed were used as seed material. According to the seed sizes (large, medium and small), the mung beans were planted in 2, 4 and 6 cm depths with 25 seeds in each pot. It is consisted of potting soil, field soil and peat (3:1) and the research was established to completely randomized plot design with three replications. In the study, germination (germination rate, germination index, mean germination time) and seedling characteristics (seedling and root length, seedling and root dry weight, above ground dry weight/total dry weight ratio) were examined. According to obtained data; while small and medium seeds characteristics germination ratio and index, root length with above ground dry weight/total dry weight ratio (medium), root dry weight and above ground dry weight (small) characteristics; large seeds have superior in mean germination time with seedling lentgh. In terms of seed depth, When germination and seedling characteristics examined, 2 and 4 cm seed depth obtained values were maximum. As a result, germination and seedling characteristics of mung bean seeds with different grain sizes were affected by planting depths. In mung bean cultivation, it has been determined that if seeds of different sizes are sown at a depth of 2-4 cm and in terms of germination and seedling growth characteristics, superior plants can be obtained.

Socio Economic Determinant and Profitability of Bari Mungbean Variety in Some Selected Areas of Bangladesh

The study was undertaken to find out the socio economic determinants and profitability of BARI mungbean variety in some selected areas of Bangladesh. The study has been conducted three district viz. Jashore, Jhenaidah and Kushtia during June-July, 2020. A total of 90 farmers, 30 from each district were selected randomly for present study. It was observed that most of the farmer cultivated BARI mung-6 (67.78%), BARI mung-5 (21.11%) and BARI mung-7 (11.11%) in the study areas. BARI mung-6 was the popular variety among the farmers in the study areas as its adaptability to diverse nature and high yield. Total cost of mungbean cultivation was Tk. 46368ha-1, where as variable cost was Tk. 27391ha-1 and fixed cost was Tk. 18977ha-1. Among the cost item highest cost was land preparation cost Tk. 7684ha-1 (16.57%) followed by hired labour Tk. 4927ha-1 (10.63%), Seed Tk. 3584ha-1 (7.73%), pod picking cost Tk. 3487ha-1 (7.52%), pesticide Tk. 3029ha-1 (6.53%), fertilizer Tk. 2740ha-1 (5.91%) etc. Pod picking is important cost at mungbean cultivation and farmer expense averages Tk.12.00/kg of green pod. Women (64%) along with children (31%) were involved in pod harvesting. Average yield of mungbean was 1.030 tonha-1 in the study areas. Average Gross return was Tk. 66966ha-1 and net return was Tk. 20598ha-1. Benefit cost ratio was 1.44 that means the mungbean cultivation was profitable. Due to not synchronous ripening of pod mungbean harvest by the mechanical was not possible. Bad weather, pod picking and insect pest attack was major constraints for mungbean cultivation.

Crop intensification with short-duration pulse crop(mungbean)using climate-smart agriculture technology in northeastern region of Bangladesh

Despite the economic progress in Bangladesh, a hot spot of hunger remained within the rapidly growing population and even the Covid-19 Pandemic made the hunger more intensive. Increasing the cropping intensity by replacing fallow with a short-duration pulse crop using climate-smart agriculture (CSA) technology in the northeastern area of Bangladesh might increase food security and the livelihood of poor farmers. Therefore, the objective of the study was to investigate short-duration mungbean crop in between the two rice-based cropping systems following CSA technology. The study was conducted at two locations following Randomized Complete Block Design (RCBD) in the farmers' field of Netrokona and Sunamganj Districts of Bangladesh during the period from March to May 2021. Results from both the study areas showed that CSA technology had substantially increased the total yield of mungbean, and BINA-8 variety performed the best results of 1061 kg/ha yield in the Sunamganj area. In mungbean cultivation, the lower tillage, 50% less fertilization, manuring, crop residues and efficient irrigation of CSA technology had a positive impact on water infiltration, soil nutrient status and water use efficiency of more than 40% compared to traditional cultivation systems. Nevertheless, the CSA in mungbean cultivation had enhanced carbon sequestration and reduces GHG emissions. The results also revealed that mungbean plant residues add an average 4.35 ton/ha green mass to the soil and saved more than 25% labor costs for mungbean cultivation. Therefore, crop intensification with mungbean using CSA technology in the disasters pruned area would be a good approach to combat food security and income generation of farmers. The study also argues that there is an immediate need for more intensive research to better quantify the mitigation effects of CSA technology.

Suppression of the soybean cyst nematode, Heterodera glycines, by short-term field cultivation and soil incorporation of mung bean

Summary Our previous study using pots reported that short-term growth of mung bean (Vigna radiata) may be useful to decrease the density of the soybean cyst nematode (SCN), Heterodera glycines, in soil. The objective of this study was to determine whether short-term growth of mung bean and its incorporation by ploughing decreased SCN density in infested fields. Firstly, we did pot experiments to evaluate the optimum temperature and moisture for hatching in soil. SCN hatching was stimulated at 25 and 30°C and not at 20°C; however, it was stimulated at alternating temperature conditions between 20 and 25°C. Soil moisture levels with pF 2.76 or less were required to stimulate SCN hatch in soil. Field experiments were done in Saitama, Kanagawa and Nara Prefectures, Japan. SCN density was reduced by nearly half even in control plots, in which mung bean was not cultivated and ploughed, in Saitama and Nara Prefectures. However, SCN density was reduced by nearly 80% or more in the three Prefectures, except for one plot in Kanagawa, and the soil temperature and moisture conditions were kept at around 20-30°C and at <pF 2.8. Increase in yield of green soybean by SCN control was estimated at 350 kg (1000 m)−2. Overall, the present study revealed that short-term field cultivation of mung bean and ploughing was a profitable method to decrease SCN density in infested fields and thereby to increase yield of green soybean.

Impact of Zinc, Boron and Molybdenum Addition in Soil on Mungbean Productivity, Nutrient Uptake and Economics

Zinc (Zn), boron (B) and molybdenum (Mo) are essential to increase the productivity of mungbean (Vigna radiata L.) and help to maintain the soil fertility but mostly ignored. Hence, an experiment was conducted during the years of 2016 and 2017 to know the impact of Zn, B and Mo on mungbean yield, nutrient uptake, economics and soil fertility improvement. The experiments were planned in randomized complete block design including of eight treatments with three replications. The treatments were T1 = Control, T2 = Zn 2 kg ha-1, T3 = B 1.5 kg ha-1, T4 = Mo 1 kg ha-1, T5 = Zn2B1.5, T6 = Zn2Mo1, T7 = B1.5Mo1 and T8 = Zn2B1.5Mo1. The other fertilizers, N, P, K and S at 20, 20, 30 and 10 kg ha-1, respectively were used in all treatments. The results indicate that the highest seed yield (1522 kg ha-1) was obtained from T8 treatment followed by T7. The highest percent seed yield increment (51.6%) over control was achieved in T8 treatment. Most of the growth and yield contributing characters of mungbean were recorded highest in T8 treatment. The maximum nodulation (37.6) and highest amount of protein (24.3%) was also obtained from T8 treatment. The T8 treatment contributed positively to attain higher total uptake of N, P, K, S, Zn and B by mungbean. The combination of Zn, B and Mo is showed more productive compare to sole or couple use of these micronutrients. The T8 (Zn2B1.5Mo1 kg ha-1) treatment exhibited helpful effects on soil organic matter, total N, available P, Zn and B. This treatment also showed economically better on the basis of net return. Results of the present study suggest that the combination of Zn, B and Mo applied at 2, 1.5 and 1 kg ha-1, respectively could be recommended for mungbean cultivation.

Additional Income Generation from Cultivation of Summer Mungbean in Rice-Wheat System of Haryana

Background: Mungbean [Vigna radiata (L.) Wilczek], also known as green gram is cultivated on area of 4.75 million ha in kharif and rabi/ spring seasons as monocrop or intercrop in India. It serves as a major source of dietary protein for the vast majority of vegetarian people in the country. Mungbean contributed 10.03 per cent of total pulses production (23.40 million tonnes) in the country with productivity level of 494 kg ha-1 in 2018-19. The pulses cultivation in Haryana is almost eliminated in kharif season owing to deviation of area towards cotton, cluster bean and pearlmillet because of low profitability. However, the new window opens for cultivation of mungbean in rice-wheat cropping system in summer season to generate additional farm income and to improve soil health. The area under summer mungbean in state was around 64 thousand ha with the production of 50 thousand tonnes and the average productivity of 780 kg/ha during 2017-18. Although rice-wheat system provides better farm returns, but it has imposed threat to soil health, availability and contamination of ground water, weed and biotic stress management. Methods: The data pertains to costs and returns from summer mungbean cultivation was gathered from 60 mungbean cultivators of Hisar, Kurukshetra and Panipat districts of Haryana having adequate irrigation water availability adopting personal interaction approach in 2018-19. Simple budgeting technique was employed to draw practical implications which ultimately help to take favourable policy decisions for enhancing acreage of summer mungbean. Result: The inquiry profound that mungbean cultivation in summer season particularly in rice-wheat was established as additional income generation farm enterprise. The net benefits accrued from short duration varieties of mungbean over variable cost was Rs. 31831 ha-1 with time span of 60-70 days by utilizing fallow land in summer season. The B-C ratio toiled considering expenses incurred on variable resources with value of 2.99 divulges economic viability of mungbean cultivation in the study area. It is imperative from results that cultivation of short duration cultivars of mungbean is viable option to enhance farm income, restoration of diminishing soil fertility owing to adoption of continuous rice-wheat rotation by inherent characteristics of converting atmospheric nitrogen. Distinctive efforts are essential to evolve mungbean cultivars suitable to prevailing cropping system in Haryana and assure market procurement. The exploration of mungbean cultivation will reduce dependency on import and improve net availability of pulses in India.

Resource Use Efficiency and Constraint Analysis of Summer Mungbean Cultivation in Rice-Wheat Cropping System

The study was conducted in eastern and western zones of Haryana in 2017-18. From eastern zone Kurukshetra and Panipat and from western zone Hisar district were selected on basis of acreage under summer mungbean. The outcomes of production function analysis reveal that there is scope for reorganization of resources used in cultivation of summer mungbean to optimize their use to enhance returns in the study area. In all the districts, the usage of resources which are showing negative production elasticity should be decreased to achieve the resource optimality and the use of resources viewing more than unity production elasticity should be encouraged to enhance the profitability condition. The analysis of constraints in cultivation of summer mungbean as opined by the sampled farmers recite that non-availability of suitable machine for harvesting, non-procurement of produce by Govt. agencies, harvest price less than MSP were recorded as the major constraints in the study area. Keeping in view the findings of the study, it is suggested that there is need to re-orient the usage of resources for attaining higher returns from summer mungbean cultivation, multiplication of short duration varieties seed, need to develop suitable and low cost harvesting machinery and procurement arrangement of produce at MSP.

Minimum Tillage and in situ Mulch Increasing the Population and Biomass of Earthworms Under Mung Bean Cultivation on Ultisol Soil

Earthworms are important soil biota that can be used as an indicator of soil fertility. Soil tillage systems and application of organic mulch will affect the activity of earthworms. This research was aimed to study the effect of tillage systems and the application of in situ mulch, and their interactions on the population and the biomass of earthworms. The study was conducted from April to July 2017 at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The study was arranged in a Randomized Block Design (RBD) in a factorial treatment with two factors. The first factor was the tillage system which consisted of the minimum tillage and the intensive tillage. The second factor was the application of in situ mulch, which consisted of the application of 0 Mg ha-1 or without mulch and the application of 5 Mg ha-1 in situ mulch.The data obtained were tested for homogeneity of variance with the Bartlett Test and its additivity with the Tukey Test. Data were further analyzed for the analysis of variance and for the LSD’s Test at the level of 5%. The relationship between soil temperature, soil moisture content, soil organic-C and soil pH with population and biomass earthworm was tested by correlation test. The results showed that the earthworm population and the earthworm biomass at 80 DAP in the minimum tillage was higher than that of the intensive tillage. The earthworm population for all detected planting stages (before tillage, 40 DAP and 80 DAP) with the of application of 5 Mg ha-1 in situ mulch was higher than that of the application of no mulch. There is no interaction between the tillage system and the application of in situ mulch at 0 DAP, 40 DAP, and 80 DAP. The genus of earthworms found in all treatment plots was genus Pheretima under the family of Megascolecidae.

Interactive effects of phosphorus and potassium on biomass production and accumulation of nitrogen in field grown mungbean (Vigna radiata L.)

A field experiment was carried out in the paddy field of Charfession Govt. College, Bhola, Bangladesh during rabi season 2017 to evaluate growth, biomass production and nitrogen accumulation in mungbean plants. The size of the plot was 60 cm x 45 cm. The distance between row to row and plant to plant was 30 cm and 10 cm, respectively. Eight plants were raised per plot. Seven treatments were P0K0 (Control), P5K6, P5K12, P5K18, P10K6, P10K12 and P10K18 kg ha-1. Forty day old plants were harvestedas root, stem and leaf. The highest plant height (17.2 cm) and number of leaves (14.3 no. plant-1) were recorded in P5K12 kg ha-1 treatment at harvest. The maximum concentration of nitrogen in root, stem and leaf were 1.59, 2.51 and 3.82% in the treatments of P5K12, P5K12 and P5K18 kg ha-1, respectively. The highest amount of dry matter yield 1.88 g plant-1 was observed in P5K12 kg ha-1 treatment. The overall better dose was P5K12 kg ha-1. Thus, a considerable amount of nitrogen and organic matter might be added to paddy fields through the cultivation of mungbean in the coastal region of Bangladesh.

Prospects of Mungbean as an Additional Crop in Rice Wheat System of Punjab Pakistan

Mungbean is a beneficial as well as crucial pulse crop which has high economical and commercial values widely grown in Asia. It is cheap source of dietary protein, iron and minerals. It belongs to family Leguminosae and is valuable grain legume which comprises major portion of proteins, minerals, vitamins and essential amino acid. In Pakistan it ranks second in Pulses production after Chickpea. Mungbean suffers from several diseases due lack of good cultural practices and insight about the genome of this crop. These diseases caused by fungus, bacterium and viruses. Major diseases including Yellow Mosaic disease (YMD), Urdbean leaf crinkle disease (ULCD), Cercospora leaf spot disease (CLSD) and were caused by yellow mosaic virus, Cercospora canesens and Urdbean leaf crinkle virus respectively. Annually, 40-80% grain yield losses were caused due to these diseases. To overcome these threats scientists/researchers are using approaches to develop resistant and high yielding Mungbean genotypes/cultivars. The area under Mungbean cultivation is decreasing day by day because most of varieties were matured at 100 to 120 days which were not suitable in our cropping pattern. There is a dire need to develop those varieties having high yield, resistant to diseases and insect pest, early and synchronize maturity (60-80 days).

Nitrogen, phosphorus, and potassium fertilization to achieve expected yield and improve yield components of mung bean.

Mung bean (Vigna radiata L.) is an important edible bean in the human diet worldwide. However, its growth, development, and yield may be restricted or limited by insufficient or unbalanced nitrogen (N), phosphorus (P), and potassium (K) fertilization. Despite this, there are few long-term studies of the effects of varying levels of N, P, and K combined fertilizers and the optimal fertilization for improving mung bean yield and quality. This study was conducted to optimize the fertilization strategies for high yield and to improve yield components (pods per plant, seeds per pod, and 100-seed weight) in the Bailv9 mung bean cultivar, 23 treatments were tested in 2013–2015, using a three-factor (N, P, and K fertilizers), five-level quadratic orthogonal rotation combination design. Our studies showed that, the N, P, and K fertilizers significantly influenced the pods per plant and yield, which increased and then decreased with the increasing N, P, and K fertilizers. The 100-seed weight was significantly affected by the N and P fertilization, and it was increased consistently with the increasing N fertilizer, and decreased significantly with the increasing P fertilizer. Whereas, the seeds per pod significantly decreased with the increasing N and K fertilizers, and the P fertilizer had no significant effect on it. The NP interaction had a significant effect on yield and pods per plant at high N levels, while the NK interaction had a significant but opposite effect on yield at low N levels. The optimal fertilization conditions to obtain yield >2,141.69 kg ha-1 were 34.38–42.62 kg ha-1 N, 17.55–21.70 kg ha-1 P2O5, and 53.23–67.29 kg ha-1 K2O. Moreover, the optimal N, P, and K fertilization interval to achieve pods per plant > 23.41 and the optimal N fertilization to achieve a 100-seed weight > 6.58 g intersected with the interval for yield, but the seeds per pod did not. The fertilizer ratio for the maximum yield was N:P2O5:K2O = 1:0.5:1.59. Following three years experimentation, the optimal fertilization measures were validated in 2016–2017, the results indicated that yield increased by 19.6% than that obtained using conventional fertilization. The results of this study provide a theoretical basis and technical guidance for high-yield mung bean cultivation using the optimal fertilization measures.
