This study aimed to determine the effect of different processing methods on the proximate composition and anti-nutritional factors of Dolichos lablab beans (Lablab purpureus) of Kenya. The seeds of KAT/DL-2 variety,sourced from Kenya Agricultural Livestock and Research Organisation, Katumani Dryland Research Station were sorted, then subjected to different processing methods (soaking, cooking and germination). The samples were analysed for proximate composition, tannins, phytates and trypsin inhibitory activity. The results showed a significant increase (2.0%) in crude protein content for germinated lablab beans while carbohydrates content was high in cooked samples. The variety KAT/DL-2 had high levels of phytates; 723.6 mg/100g and tannins 330.3mg/100g and trypsin inhibitor activity 1.3mg/100g. Cooking achieved the highest reduction of anti-nutrients with 88% reduction in TIU. The results revealed that the anti-nutrients in lablab beans can be reduced using different methods of processing. However, there is need to investigate the effect of combined methods on the nutrients and anti-nutrients.

The present study was carried out to evaluate the rehydration characteristics of solar and mechanically dried lablab bean (Lablab purpureus (L.) sweet; hitherto Dolichos lablab) seeds. Bean seeds with and without coat were used to study the rehydration properties. The rehydration ratios were higher for both mechanically and solar dried bean seeds without seed coat than those with coat. Mechanically dried without coat bean seeds had rehydration ratio of 2.34 while with coat was 2.06. For mechanically dried samples, the co-efficient of reconstitution were 0.58 and 0.56 for bean seeds without and with coat, respectively, and were higher than those of solar dried samples having co-efficient of reconstitution of 0.54 and 0.52 for bean seeds without and with coat, respectively. For both mechanical and solar drying the rehydration rate constant was higher for bean seeds without coat than those with coat. Both rehydration ratio and rehydration rate indicated that mechanically and solar dried bean seeds samples without coat showed better reconstitution properties than those with coat. Both fresh and dried bean seeds without seed coat gave higher nutrient content than their counterpart with coat. Solar and mechanical dried seeds were good source of nutrients.

Una alternativa para mejorar la calidad de las dietas para el ganado lechero, es mediante el uso de leguminosas anuales. El objetivo del presente estudio fue comparar la composición nutricional y los rendimientos potenciales de materia seca (MS) y nutrientes de cuatro especies leguminosas anuales durante el periodo disponible en el ciclo de verano en la Comarca Lagunera. El experimento se estableció el cinco y ocho de julio de 2005 y 2006, respectivamente, en el Campo Experimental La Laguna del INIFAP localizado en Matamoros, Coahuila, México. Se evaluaron dos genotipos de chícharo de vaca (Vigna unguiculata L.), uno de frijol gandul (Cajanus cajan L.), cuatro de soya (Glycine max L.) y uno de frijol dolichos (Lablab purpureus L.). Se utilizó un diseño experimental de bloques completos al azar con cuatro repeticiones. Se determinó el rendimiento de MS, distribución de MS en la parte aérea y composición química del forraje. Los rendimientos de soya (7 757-9 280 kg ha-1) fueron superiores (p≤ 0.05) a los de chícharo de vaca, frijol gandúl y frijol dolichos (2 200-6 132 kg ha-1). Los mejores resultados se obtuvieron en soya ‘Hutchinson’ (p≤ 0.05), debido a sus altos rendimientos de MS, energía neta para lactancia (ENl) y proteína cruda (PC) por hectárea, además de su buena composición nutricional, medida en términos de contenidos de PC (228-242 g kg-1), ENl (1.48-1.58 Mcal kg-1 MS) y fibra detergente neutro (318-335 g kg-1). Su baja asignación de MS hacia el tallo y su precocidad propiciaron una mayor proporción de vainas en el forraje (p≤ 0.05) incrementando la composición nutricional durante el ciclo de verano.

In a field experiment at Beerwah, Queensland, bauxite pellet applied with 4 per cent methyl cellulose sticker and 1 per cent methyl cellulose as a simple sticker for the inoculant were compared with the standard treatments used successfully in a previous series of experiments. These were peat applied with 4 per cent methyl cellulose, and Florida rock phosphate pellet with 4 per cent methyl cellulose sticker. Legumes and Rhizobium strains tested were Desmodium uncinatum and D. intortum, inoculated with Rhizobium CB627, Lablab purpureus (formerly Dolichos lablab), Glycine wightii (three cvs. Clarence, Cooper and Tinaroo), and Macroptilium atropurpureum (formerly Phaseolus atropurpureus), all inoculated with Rhizobium CB756, and Lotononis bainesii inoculated with Rhizobium CB376. All were planted after 2-day and 28-day storage of inoculated seed. The effectiveness of the treatments was checked by nodule counting and by serologically identifying the strains in a random sample of nodules from each treatment. The majority of nodules formed came from the applied inoculants, but there were no differences between the inoculation treatments in nodulation criteria or effect on yield. The experiment confirmed that bauxite is a satisfactory pelleting material for tropical legumes, but the application of the inoculant peat with 1 per cent methyl cellulose leads to equally good nodulation.

The Relationship

The seasonal dynamics of aphid Aphis craccivora Koch (Hemiptera: Aphididae) on four bean species namely country bean Lablab purpureus, yard long bean Vigna sesquipedalis, hyacinth bean Dolichos lablab and bush bean Phaseolus vulgaris were studied from September to December 2017 in the experimental field of the Department of Entomology, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh. The study also investigated the relationship between the abundance of aphid and its predatory insect lady bird beetle. Aphid abundance on the bean species showed increasing trend from the 4th week of September and reached to the peak during the 2nd week of November and then declined. Bush bean and yard long bean, respectively depicted the higher and lower abundances of aphid throughout the study. Relationship between the abundance of aphid and lady bird beetle on the bean species were positively correlated. Aphid showed negatively correlation with temperature and rainfall, and positive correlation with relative humidity, and the correlations were not significant. Multiple regression equation showed that temperature had the highest effect which contributed 16.1 - 19.2% role on the population of aphid. Bangladesh J. Zool. 48(2): 357-363, 2020

Set Up

The traditional natural fallows are no longer practicable in sub-Saharan Africa and technologies to replace them are being popularised through management of short fallow systems. Dolichos [Lablab purpureus (L.) Sweet] is among the legumes used to improve such fallows and its residues are incorporated to improve yield of succeeding cereal. Two field studies were conducted to determine dolichos residue mineralisation schedule and response of maize to timing of the residue incorporation, to establish if the current residue incorporation practice maximises nutrient benefit to succeeding cereal. Dolichos residue was applied at 2 t/ha in litterbags, buried in the field at 15-cm depth and retrieved after 1, 2, 4, 8 and 16 weeks, and the remaining debris analysed for loss of weight, N, P and K. A parallel split-plot experiment was set up to determine response of maize to time of residue incorporation, with or without fertiliser nitrogen supplementation. The main plot treatments were nitrogen fertiliser applied at 0, 30 and 60 kg/ha at sixth fully opened leaf in maize. The subplot treatments were residue management regimes, which included four residue incorporation times of 2, 4, 6, and 8 weeks before sowing maize, residue removal off the field, residue mulched on surface and traditional weedy fallow. Results show rapid loss of N, with 50% being released within the first 2–4 weeks after burying. Residue incorporated at 2 and 4 weeks before sowing improved maize yield, while residue removal off-field reduced yield comparably with the traditional weedy fallow. However, there were no statistical differences among the timing of the dolichos residue incorporation. These results reflect poor synchrony of mineralised N and uptake by succeeding maize as currently practiced and suggest residue incorporation closer to sowing maize to benefit the cereal.
