The performance of neem based agroforestry system was studied during 2016-17 under rainfed ecosystem on farmers’ fields on participatory mode in Yadagir district in the North-eastern dry zone (Zone II) of Karnataka. Grain and biomass yields and harvest index of pigeonpea did not vary significantly among the agroforestry systems. However, significantly lower grain (1192 kg ha-1) and biomass (5563 kg ha-1) yields of pigeonpea were recorded at 5 m distance away from the neem tree line (P=0.05) compared to the distances of 10 m ( 1450 and 6942 kg ha-1, respectively) and 15 m (1449 and 6720 kg ha-1, respectively) away from the tree line. Significantly higher grain yield (1520 kg ha-1) was observed in control without any proximity of trees compared to the agroforestry systems which accounted for a mean reduction of 11 per cent in yield. Among different agroforestry systems, significantly higher tree height was recorded in bund planting (7.61m) followed by boundary planting (7.38 m) and scattered planting (6.46 m) whereas the crown spread recorded was significantly lower in bund planting (6.27 m) followed by scattered planting (6.38 m) and boundary planting (6.68 m). There also existed non-significant difference in girth, volume and biomass of neem trees grown in different agroforestry systems. Further, the physicochemical properties of soil were found improved in agroforestry systems compared to control and the trend varied among the different agroforestry systems

The productivity of teak based agroforestry system was studied during 2016-17 under irrigated ecosystem in Yadagir district of North-eastern dry zone (None II) of Karnataka. Significantly lower pigeonpea grain yield (1766 kg ha-1) and biomass yield (8207 kg ha-1) in association with teak were recorded at 5 m away from the tree line compared to the crop at a distance 10 m (2345 and 10089 kg ha-1, respectively) and 15 m (8207, 10526 kg ha-1, respectively) away from the tree line whereas harvest index remained unaffected. Non-significant differences were observed in grain yield and harvest index, albeit numerically higher grain yield were recorded in the control (2316 kg ha-1) without teak nearby compared to the agroforestry systems and within agroforestry systems boundary planting recorded numerically higher grain yield (2228 kg ha-1) than with bund planting (2081 kg ha-1). Significantly higher girth, volume and biomass of teak were recorded in bund planting (76.37 cm, 0.390 m3 and 215 kg, respectively) followed by silvi-horti system (72.65 cm, 0.381m3 and 209 kg, respectively) and boundary planting (69.10 cm, 0.342 m3 and 215 kg, respectively), whereas significantly lower girth, volume and biomass were recorded in block plantation (51.45 cm, 0.182 m3 and 100 kg, respectively). The study also revealed significantly lower crown spread in block plantation (2.85 m) followed by boundary planting (4.63 m).

The Impact

Total aboveground carbon (TAC) and total soil carbon stock in the agroforestry system at the Balung River Plantation, Sabah, Malaysia were investigated to scientifically support the sustaining of natural forest for mitigating global warming via reducing carbon in the atmosphere. Agroforestry, monoculture, and natural tropical forests were investigated to calculate the carbon stock and sequestration based on three different combinations of oil palm and agarwood in agroforestry systems from 2014 to 2018. These combinations were oil palm (27 years) and agarwood (seven years), oil palm (20 years) and agarwood (seven years), and oil palm (17 years) and agarwood (five years). Monoculture oil palm (16 years), oil palm (six years), and natural tropical forest were set as the control. Three randomly selected plots for agroforestry and monoculture plantation were 0.25 ha (50 × 50 m), respectively, whereas for the natural tropical forest it was 0.09 ha (30 × 30 m). A nondestructive sampling method followed by the allometric equation determined the standing biomass. Organic and shrub layers collected in a square frame (1 × 1 m) were analyzed using the CHN628 series (LECO Corp., MI, USA) for carbon content. Soil bulk density of randomly selected points within the three different layers, that is, 0 to 5, 5 to 10, and 10 to 30 cm were used to determine the total ecosystem carbon (TEC) stock in each agroforestry system which was 79.13, 85.40, and 78.28 Mg C ha−1, respectively. The TEC in the monoculture oil palm was 76.44 and 60.30 Mg C ha−1, whereas natural tropical forest had the highest TEC of 287.29 Mg C ha−1. The forest stand had the highest TEC capacity as compared with the agroforestry and monoculture systems. The impact of planting systems on the TEC showed a statistically significant difference at a 95% confidence interval for the various carbon pools among the agroforestry, monoculture, and natural tropical forests. Therefore, the forest must be sustained because of its higher capacity to store carbon in mitigating global warming.

AbstractIt has been suggested that iodine plays an important role in gastric cancer. Gastric cancer ranks first among the cancers in the north-eastern Anatolia region, Turkey, where iodine deficiency is common. In this study, iodine levels were determined in gastric cancer and surrounding normal tissues in 19 patients with gastric cancer. Tissue iodine levels were determined by the Foss method based on the Sandell-Kolt-hoff reaction. Tissue iodine levels were lower in gastric cancer tissue (17.8±3.4ngI/mg protein, mean±SEM) compared with surrounding normal tissue (41.7±8.0ngI/mg protein) (p<0.001). There was positive correlation between the iodine levels in gastric cancer tissue and surrounding normal tissue (r=0.845, p<0.001). There was no significant difference in iodine levels in cancer and surrounding normal tissue between male and female subjects. The iodine deficiency in our region may be one of the factors for increased gastric cancer prevalence. Our results support the hypothesis that iodine plays an important role in gastric cancer development.

Agroforestry Practices

Agroforestry practices offer a unique opportunity to address climate change impacts while securing the livelihoods of the rural communities. This study was carried out in Tillotama municipality of Rupandehi district, Nepal. Agroforestry system practices at the study site were identified through reconnaissance survey and discussions with ward officials. With 10% sampling intensity, purposive sampling was adopted for the study using the structured questionnaire, key informant interview, and field observation. For mean comparison, one-way ANOVA and Least Significant Difference (LSD) as post-hoc tests were carried out. Local communities were adopting eight different types of agroforestry practices under four agroforestry systems, namely agri-silvicultural, silvo-pastoral, agro-silvopastoral and silvi-fishery. The agroforestry system shared up to 50.54% of total households’ income, in which income from agriculture was the highest. Agroforestry income was dependent on the economic status of the households. Change in cropping calendar was found as a major adaptation strategy. Scaling up of agroforestry system and commercialization of agroforestry products were recommended.

"Conoro" is a traditional fermented condiments prepared from seeds of Baobab, Kapok and Okra. It is consumed by the North-Eastern Ivoirians. The aim was to report ethno-nutritional knowledge of "conôro" and to understand theirs uses. Data showed that respondents had a high knowledge level of "conôro" (86 to 96.67%). A significant difference is found in ethnic and age groups (p <0.05). Koulango were majority ethnic and people over 65 years old had the high knowledge level of "Conôro" to 96.8-100 % and 85.7-100 % respectively. Conoro’s utilization rates varied between 85.27 to 97.93 %. Sauces seasoning (ICF = 0.92) and addition of "Conôro" to other natural substances (ICF = 0.46) were respectively the most reported food and therapeutic uses. Blood pressure (ICF = 0.19) and abdominal pain after childbirth (ICF = 0.33) represented the most common treated diseases. "Conôro" was made from seeds taken individually or combined. The production processes of "conôro" were studied in different localities. Fermentation took 3 days in all localities. It was sold in dumpling form at 25 to 100 FCFA. The conservation time of "conôro" was from 6 to 12 months.

Performance of developed genotype RMT 08-2 was evaluated in central, eastern and north-eastern states of India under rain-fed condition for quantitative and qualitative traits. It gave highest seed yield over checks in zone III and V. Morphologically plants were erect, medium spreading in nature and primary branches with dichotomous habit. Plants height ranged from 107124 (cm) which matured in 82-112 days. Mature seeds were round in shape and blackish brown in colour. No significant difference between RVT-2 and checks were observed for test weight trait. An average oil yield 485 (kg/h) was recorded over 7 places which was 10% higher than both checks i.e. 14.12% and 11.24% under AICRP trials. Maximum seed yield was obtained on farmers field during 2013-14 and 2014-15 which was 1500 (kg/h) and 1215 (kg/h) that is 33.42% and 26.30% respectively over farmers own seeds. At Morena center, highest seed yield (1753 kg/h) over Bhawani (1512 kg/h) was 15.94% higher than check whereas RVT-2 gave 2245 (kg/h) against Bhawani (1975 kg/h) which was 13.67% higher. DNA finger printing indicated that primers PUT-19, PUT-96, PUT-149, PUT-169, PUT-181 and PUT-271 are useful in generating unique profile of RVT-2 containing 27 bands for its discrimination from other varieties.

On June 7, 2018, a sub-mesoscale anticyclonic eddy induced by the wind (north-east) was registered on the shelf in the area of the city of Gelendzhik. With the help of field multidisciplinary expedition ship surveys, it was shown that this eddy exists in the layer above the seasonal thermocline. At the periphery of the eddy weak variability of hydrochemical parameters and quantitative indicators of phytoplankton were recorded. The result of the formation of such eddy structure was a shift in the structure of phytoplankton – the annual observed coccolithophores bloom was not registered.

Com este trabalho foi possível estabelecer relações entre a quantidade de água aplicada e produtividade de grãos, para três variedades de feijão caupi submetidas a diferentes lâminas de água. Para caracterização das lâminas de água foi utilizado um sistema de irrigação por aspersão convencional em linha. O controle da irrigação foi realizado a partir de tensiômetros instalados à 15 cm de profundidade. Os resultados mostraram que: i) a cultivar João Paulo II apresentou melhores resultados de produtividade para as lâminas de água aplicadas que variaram de T1 = 291,8 mm a T5 = 141,2 mm; ii) sob condições de reduzida disponibilidade de água, ou seja, menor lâmina aplicada, não ocorreu diferença estatística  para a produtividade entre as cultivares estudadas; e iii) para as condições do estudo, a cultivar Setentão apresentou a menor taxa de redução do produto marginal.       UNITERMOS: caupi, irrigação, função de produção       LIMA, G.

Responses OF cowpea cultivars (Vigna unguiculata L Walp) at differents irrigation deficits     2 ABSTRACT       The caupi is one of the most traditional cultivation of the north and northeast - Brazil, constituting a basic food in these areas. With this work it was possible to establish relationships between the amount of water applied and productivity of grains, for three caupi varieties submitted to different irrigation sheets. To diferentiate water depths in the irrigation system, the aspersion in line was used. The control of the irrigation was accomplished using tensiometers installed to 15 cm of depth. The results showed that: i) the João Paulo II variety presented better productivity for the applied water depths; ii) under reduced conditions of water avai lability for study conditions, these was no significant difference in the productivity reached among the cultivars studied; and iii) for the conditions of the study, the variety Setentão presented the smallest rate of reduction of the marginal product.       KEYWORDS: cowpea, irrigation, production function
