TL;DR: Levels of nitrogen fixation and yield achieved on-farm were measured in commercial faba beans and other winter and summer legume crops sown after cotton over 3 years to assess the relative inputs of fixed nitrogen into this system.
Abstract: Summary. Legumes have become common rotation crops in cotton cropping systems in northern New South Wales. Levels of nitrogen fixation and yield achieved on-farm were measured in commercial faba beans and other winter and summer legume crops sown after cotton over 3 years to assess the relative inputs of fixed nitrogen (N) into this system. Faba bean crops fixed up to 350 kg N/ha, removed up to 160 kg N/ha in harvested grain and contributed up to 270 kg fixed N/ha to soil N after harvest. Grain yields, N2 fixation and dry matter production were reduced in late-sown crops and those water-stressed during pod-filling, but most faba bean crops fixed almost 3 times as much N as was removed in grain. Below-ground legume N, determined with 15N shoot feeding techniques, accounted for 40% of the total crop N at peak biomass, or about 100 kg N/ha for the average faba bean crops. Residual fixed N after harvest was predicted from crop dry matter and grain yield, and this could be used to assess the contribution to soil N from faba beans. Amounts of nitrogen fixed by other legume crops ranged from 20 kg N/ha for adzuki bean and droughted lablab to more than 450 kg N/ha by irrigated soybean. Soybean, peanut and Dolichos lablab contributed more fixed N to the soil than adzuki bean, mung bean or pigeon pea under irrigated conditions. Winter crops including field peas, lentils and lupins and green-manured pasture species fixed up to 240 kg N/ha.

TL;DR: In this paper, the authors evaluated the effect of long-term (19 and 21 years) no-till maize crop rotations including grass [black oat (Avena strigosa Schreb)] and legume cover crops [vetch (Vigna sativa L.), cowpea, pigeon pea (Cajanus cajan L. Millsp), and lablab (Dolichos lablab)] on annual soil N2O emissions in a subtropical Acrisol in Southern Brazil.
Abstract: It has been shown that cover crops can enhance soil nitrous oxide (N2O) emissions, but the magnitude of increase depends on the quantity and quality of the crop residues. Therefore, this study aimed to evaluate the effect of long-term (19 and 21 years) no-till maize crop rotations including grass [black oat (Avena strigosa Schreb)] and legume cover crops [vetch (Vigna sativa L.), cowpea (Vigna unguiculata L. Walp), pigeon pea (Cajanus cajan L. Millsp.) and lablab (Dolichos lablab)] on annual soil N2O emissions in a subtropical Acrisol in Southern Brazil. Greater soil N2O emissions were observed in the first 45 days after the cover crop residue management in all crop rotations, varying from � 20.2 � 1.9 to 163.9 � 24.3 m gNm � 2 h � 1 . Legumebased crop rotations had the largest cumulative emissions in this period, which were directly related to the quantity of N (r 2 =0 .60, p= 0.13) and inversely related to the lignin:N ratio (r 2 =0 .89, p= 0.01) of the cover crop residues. After this period, the mean fluxes were smaller and were closely related to the total soil N stocks (r 2 =0 .96,p = 0.002). The annual soil N2O emission represented 0.39–0.75% of the total N added by the legume

TL;DR: Germination increased the in-vitro protein digestibility of the endosperm of Dolichos lablab in the presence of proteolytic enzymes like pepsin, trypsin and pancreatin and showed a negative but non-significant correlation withtrypsin inhibitory activity, phenolics and tannin contents.
Abstract: A gradual decrease was noted in total protein, soluble protein and protein fractions such as albumin, globulin, prolamine andglutelin in the endosperm of Dolichos lablab L germinated for 8 days. Prolamine showed a maximum decrease of 85% whereas only a 25% decrease was noted in the globulin fraction. Both acid and alkaline protease activities increased during germination, and the acid protease activity was consistently higher than the alkaline protease activity throughout. Electrophoretic studies showed that high molecular weight polypeptide bands disappeared with the appearance of new low molecular weight polypeptide bands in the endosperm proteins of the germinating seeds. Total phenolics and tannin contents and trypsin inhibitory activity also increased during the progressive germination. Germination increased the in-vitro protein digestibility of the endosperm of Dolichos lablab in the presence of proteolytic enzymes like pepsin, trypsin and pancreatin. It showed a negative but non-significant correlation with trypsin inhibitory activity, phenolics and tannin contents. Amylase activity also increased gradually up to the sixth day of germination which coincided with the increase in the reducing sugars.

TL;DR: In this paper, the mature seeds of five cultivars of dolichos beans (lablab L) were analysed for some nutritional and antinutritional factors, including crude protein, crude fibre, 7·62 to 9·63 and total carbohydrate, 54·2 to 63·3.

TL;DR: The phytochemical analysis of Dolichos lablab showed that it contained sugar, alcohols, phenols, steroids, essential oils, alkaloids, tannins, flavonoids, saponins, coumarins, terpenoids, pigments, glycosides, anthnanoids, wide range of minerals and many other metabolites.
Abstract: The phytochemical analysis of Dolichos lablab showed that it contained sugar, alcohols, phenols, steroids, essential oils, alkaloids, tannins, flavonoids, saponins, coumarins, terpenoids, pigments, glycosides, anthnanoids, wide range of minerals and many other metabolites. The preliminary pharmacological studies revealed that Dolichos lablab possessed antidiabetic, antiinflammatory, analgesic, antioxidant, cytotoxic, hypolipidemic, antimicrobial, insecticidal, hepatoprotective, antilithiatic, antispasmodic effects and also used for the treatment of iron deficiency anemia. The current review discussed the chemical constituents and pharmacological activities of Dolichos lablab.
