Activity of the pest in fruits was observed higher as compared to shoots with the peak (28.26%) during 3rd week of November. Among different varieties, the highest (424.62 q/ha) fruit yield was harvested from the variety Doli-5 with reporting `resistant`. Among the seven treatments, neem oil @ 0.5% was found significantly superior and recorded the lowest (7.77) per cent shoot damage with the highest (1:35.80) Incremental Cost Benefit Ratio (ICBR) in the plots treated with neem oil @ 0.5%. ····· 1036191854
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The link between forests and poverty reduction in developing countries is a subject of considerable interest. Studies have revealed a high dependence on forest resources by neighboring communities for purposes of sustaining livelihoods. However, most studies have focused on the role of Timber products ignoring the vital role of Non-Timber Forest Products in alleviating poverty. Clearly, there exist knowledge gaps on the social aspects of forests, in particular, on the impacts of forest resources on household poverty. This book is an outcome of a field survey conducted in Cherangany Hills, Kenya, to investigate the poverty reducing effect of forests. It uses both qualitative and quantitative analyses to highlight the Poverty-Environment linkages in the forestry sector. The findings should particularly be helpful to conservationists and development practitioners in Government and Civil Society aiming at mainstreaming forestry into poverty reduction strategies. ····· 1036191822

The symptoms of disease first appears on the stems as necrotic spot and later turns to canker resulting in wilting of whole plants. The media most suited for mycelial growth was potato dextrose agar and the optimum temperature was 30 0c. Formation of different biological structures like mycelium, pseudo-parenchymatous tissues, pycnidium and pycnidiospore release from pycnidia were depicted. Vitavax was found most effective fungicide to check mycelium growth in vitro at 550 ppm concentration and among botanicals, neemol was found effective.

Thus, soil characterization and field experiment was conducted to investigate the effects of applied N and P fertilizer rates on grain yield and yield components for triticale (Triticosecale wittmack L.) production on soils of Wabela, around Debretabor area, Amhara National Regional State (ANRS). The experiment involved factorial combinations of four rates of N (0, 23, 46 and 69 kg ha-1) and P (0, 10, 20 and 30 kg ha-1) laid down in RCBD with three replications. The moist soil color of the profile was very dark brown (7.5YR 3/3), at the surface and dark grayish brown (10YR 3/3) at the bottom, with clay loam to clayey texture. The bulk density values varied with depth of the profile from 1.01 g cm-3 at the surface layer to 1.23 g cm-3 at the bottom layer.

Formal survey was carried out on a total of 90 households (HHs) was selected using stratified random sampling. The experimental design of Randomized Complete Block Design (RCBD) was used to examine barley yield at different distance from the bamboo line. The results indicate that The income from bamboo accounted for about 17% of the total household annual income Moreover, the role of bamboo in environmental protection was assessed from farmer s perception and almost about 82% of the respondents believed that bamboo increases soil fertility.

Effect of climate change on yield of two varieties of boro rice has been assessed using the DSSAT (v4) modeling system. The yield of BR3 and BR14 boro varieties for the years 2008, 2030, 2050 and 2070 have been simulated for 12 locations of Bangladesh, which were selected from among the major rice growing areas in different regions of Bangladesh. Available data on soil and hydrologic characteristics of these locations, and typical crop management practice for boro rice were used in the simulations. The weather data required for the model (daily maximum and minimum temperatures, daily solar radiation and daily precipitation) were generated for the selected years and for the selected locations using the regional climate model PRECIS. The model predicted significant reduction in yield of both varieties of boro rice due to climate change yield reductions of over 20% and 50% have been predicted for both rice varieties for the years 2050 and 2070, respectively. ····· 1036191737

Rubber plantation at a maximum age of 40 years could stored up to 468.69Mg/ha Carbon in its tree biomass while a 6 year old plantation of the same species has carbon budget of 31.87Mg/ha. It also revealed that the different C pools of rubber tree significantly related to its total carbon density. The age range of 6-12 years plantation is found to be statistically different with age range 20-40 years. This implies that carbon trapping potentials of rubber tree is highly dependent on age of plantation. on the other hand, the study on the success of stem cut rubber for mass propagation, it was found that older stem parts (brown cuttings) applied with alpha naphthalene acetic acid (ANAA)at a concentration of 1tbsp/3litH2O has 74% survival rate with maximum sprouts and root growth. This is a good indicator that stem cut rubber can be mass propagated even in rural farm level nurseries at minimal cost and labor.

Terrestrial ecosystem, in which carbon is retained in above ground biomass, underground biomass and in soil, plays a vital role in Carbon Cycle. Most of the community forests in Nepal are recognized as major contributors for fuel wood, fodder, timber and non-timber forest products. Furthermore, Community forests help to conserve wild fauna, soil and water, and also provide an opportunity for income generating activities and institutional development. Also, there is a high potentiality in making income from carbon credit in Community Forestry System under market adoption of Clean Development Mechanism (CDM), a frame work of the Kyoto Protocol.

The starch samples were also used in the production of cookies at 5%, 10%, 15%, 20% and 25% level of substitution with wheat flour. The cookies produced were subjected to proximate analysis and sensory evaluation. The result of the sensory evaluation showed that cookies prepared at 5% level of substitution were most acceptable. After eight weeks of storage in light polythene bags, the cookies prepared at 5% and 10% levels of substitution with wheat flour were found to be more acceptable by the panelists. Observations on the functional properties showed that the modified cocoyam starches exhibited higher bulk densities than the untreated starches.

Understanding the effect of processing parameters against the yield of rotenoids resin, rotenone and their biological activities are essential in designing a better processing technology to maintain and preserve the bio-active constituents in the extracts and rotenoids resin effectively. Although genus Derris roots have been identified as a potential cash crop due to its abundance growth in Malaysia, no research work of its own native species has been conducted locally.

To satisfy the concept of precision farming, rapid and intensive soil sampling is necessary for describing the uncertainty within a field. Apparent or bulk soil electrical conductivity (ECa) technique for describing soil spatial variability is widely used. ECa includes soil salinity and soil texture. Soil texture has high correlation with soil cation exchange capacity (CEC) hence, soil nutrient contents.The study showed that most of the soil properties and ECa changed from one season to other seasons, except total N. Many soil properties had the same mean values for seasons 1 and 3 such as K, moisture content, silt and coarse sand. Spatial variability of shallow and deep ECa had the same pattern for different seasons even though the mean values were different.

The exponential relationship between cotton yield and seasonal heat unit input was best fitted. The seasonal yield production function was found best fitted in second order polynomial form. The Jenson multiplicative model was found to be the best fitted for describing the effects of both timing and quantities of water consumption on crop yield. The data of benefit-cost ratio showed that under highly deficit and fully water supply conditions, the drip system adoption was not economically desirable. The developed nomographs were found versatile tools for the land and water resources planning.
