Nutrients Content and Antioxidant Potential of Selected Traditional Vegetables Grown in Malawi

Abstract: Vegetables provide nutrients, especially minerals and vitamins, and non-nutrient phytochemicals with health benefits. Iron, zinc and vitamin A deficiencies are common in most developing countries yet traditional vegetables that can provide these nutrients grow wildly in most areas. This study evaluated the nutrient contents, phytochemicals and the 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activities of five traditional leafy vegetables grown in Malawi, namely Amaranth hybridus (Amaranth ssp.), Moringa oleifera ( Drum stick), Bidens pilosa (Black jack), Corchorus olitorius (Jute mallow) and Ipomea batatas (Sweet potato) leaves. Results from the present study show that beta-carotene ranged from 829.68 µg/100g to 5,791.64 µg/100g and Moringa oleifera had the highest concentration. Vitamin C content ranged from 7.93 mg/100g to 35.81 mg/100g and Ipomea batatas leaves had the highest concentration. Zinc concentrations ranged from 4.42 mg/100g to 10.59 mg/100g. Iron content ranged from 37.22 mg/100g to 48.21 mg/100g. Total phenolics content (TPC) ranged from 0.98 g/100g to 3.89 g/100g with Bidens pilosa leaves having the highest TPC (3.89±0.23 g/100g). Moringa oleifera and Bidens pilosa leaves had significantly higher (P Corchorus olitorius > Moringa oleifera > Ipomea batatas > Amaranth hybridus . The 50% inhibitory concentration (IC 50 ) values of these vegetables ranged from 12.5 µg/mL to 125 µg/mL. Lower IC 50 values indicate higher radical scavenging activity. The results suggested that the traditional vegetables under the study can significantly contribute to improved human nutrition and have potential to reduce diseases related to oxidative stress.

Strip-cropping of legumes with jute ( Corchorus olitorius ) in jute-paddy-lentil cropping system

Abstract: Tossa jute (Corchorus olitorius L.) is a very important cash crop and the main fibre crop of eastern India especially for West Bengal (72% area, 78% production). It is already established that day-by-day the probability of getting timely onset of monsoon and the quantum of rainfall receiving are reducing in the country, in general and in the jute growing belt, in particular. Being a traditionally considered rain-fed crop, jute at the early phase of growth suffers from severe moisture stress and faces even drought like situation often due to such aberration in the monsoon behaviour. In some extreme years of moisture stress, crop failure can not be ruled out. Vast majority of jute farmers are small and marginal having poor resource base and therefore, they are not in a position to cope up the situation of crop failure. To overcome the uncertainty, strip cropping of carefully chosen legumes can be practiced which may act as insurance against partial or even complete failure of jute crop. Legumes are considered as essential components of a viable cropping system, particularly for its role as a fixer of atmospheric nitrogen in soil and as a potent source of edible protein through pulses. Besides, legume being a fast growing cover crop with low water requirement able to smother weeds effectively and can reduce the cost towards manual weeding. The present investigation is aimed at utilizing the kharif legumes like cowpea [Vigna unguiculata (L.) Walp.], green gram [Vigna radiate (L.) Wilczek], black gram [Vigna mungo (L.) Hepper] and rice bean [Vigna umbellate (Thunb.)] as companion crops in strips (20% area) with jute without reducing its population to augment jute fibre equivalent yield and reduce the cost towards weeding in particular. This practice may also encourage the production of more number of jute plants with reduced basal diameter to yield superior fibre quality (Pal et al., 1981). The field experiment was conducted for consecutive two years from 2006 to 2007 at the main farm of Central Research Institute for Jute and Allied Fibres (22.75°N, 88.43°E, 3.14 m AMSL) The experimental soil was Typic Ustochrept with sandyloam texture having neutral pH 7.23 (1:2.5 w/v), organic carbon 5.50 g kg, medium in fertility (available N, P and K were 332, 33 and 148 kg ha respectively). Legumes were grown as strips of 1.5 m width with jute by narrowing jute inter-row spacing from 25 cm to 20 cm and allocating the additional space (20%) for legumes without sacrificing plant density of the main crop The treatment combinations were: T1: Jute (20 cm row) in 80% area + cowpea as grain crop in 20% area; T2: Jute (20 cm row) in 80% area + green gram as grain crop in 20% area; T3: Jute (20 cm row) in 80% area + black gram as fodder crop in 20% area; T4: Jute (20 cm row) in 80% area + rice bean as fodder crop in 20% area; T5: Jute (20 cm row) alone; and T6: Jute (25 cm row) alone. In strip cropping treatments, jute: legumes area was in 4:1 ratio. The intercrop varieties were Pusa Kamal (cowpea), PS 16 (green gram), T9 (black gram) and K1 (rice bean). The varieties for the succeeding crops were B 77 (lentil) and Khitish (paddy). The experiment was laid in RBD with 4 replications. Both black gram and rice bean were sown as broadcast for fodder, while green gram and cowpea were sown in lines spaced 30 cm apart for grain production. The legumes as fodder was harvested at 60 days crop age. Weed dry matter was recorded at 21 days after sowing. The jute equivalent yield of different crop was calculated. Plant height, basal diameter and yield of jute The plant height of jute varied significantly when grown in different strip-cropped system with legumes (Table 1). The highest jute plant height in black gram treatment (227 cm) was at par with cowpea (221 cm) and rice bean (217 cm). Like plant height, similar trends were also observed in case of basal diameter of jute. The general trend of reduction in basal diameter of plants grown with reduced interrow spacing of 20 cm proved beneficial for quality jute fibre production due to more uniform retting. The fibre yield of jute (grown alone) in 20 cm row spacing (29.6 q ha) and in 25 cm rowed crop (28.1 q ha) were at par. Earlier it was reported that growth and yield performance of pepper can be enhanced in mixture with jute at a plant population of 0.1 million per ha (Loveth, 2006). The fibre yield of jute was not varied significantly among the different treatments.

First identification and characterization of cucumber mosaic virus from Corchorus olitorius in Japan

Abstract: CMV infected in Corchorus olitorius plants cultivated on a farm in Miyagi Prefecture, Japan, was analyzed via western blotting using antibody against the coat protein of cucumber mosaic virus (CMV). The virus was purified from Nicotiana benthamiana leaves rub-inoculated with a homogenate of infected C. olitorius containing CMV genomic RNA. The CMV isolate was named CMV-Co-46. Nucleotide sequence analysis of RNA1, 2, and 3 cDNA grouped CMV-Co-46 in subgroup IA. Inoculation of C. olitorius cotyledons with CMV-Co-46 resulted in slight yellowing on primary and secondary leaves seven days after inoculation and severely suppressing plant growth. However, no further systemic spread was observed and the infected plants were able to recover from the stunting symptoms. These findings suggest that restricted infection followed by recovery from systemic stunting may be a unique feature of the C. olitorius response to CMV. Management of CMV infection at an early growth stage is therefore important in obtaining healthy nursery plants of C. olitorius.
