It also gives a brief overview of the economic importance of the forests and the legal and institutional framework for the forest sector in India. Forest Strategy is inadequate to cope with all the diverse demands that India faces in the sector. India needs a balance of its three policy orientations production forestry, afforestation, and protection/regeneration to have an effective forest strategy, in addition to an enabling environment that promotes research and extension and private sector participation. Support for production forestry does not imply agreement with the essential features of industrial forestry, like replacement of natural forests with monoculture. It merely implies incorporation of a production oriented approach. ····· 10361147166

Consequently, it was possible to reduce water and nutrient loss, which could also help to reduce the environmental pollution. Consequently, it can be said that the obtained equations can be used to establish an easy way to predict the values of crop coefficient (Kc) and root volume and distribution at any time after planting during the same growth season and in the regions having similar climatic conditions. Moreover, these equations could be used with the irrigation scheduling programs in Egyptian software which programmed in Central Laboratory for Agricultural Climate (CLAC). Growers should pay attention to crop appearance, soil water tension, the rate of crop evapotranspiration, precipitation, and the amount of water applied. With knowledge of these factors, irrigation can be well managed in order to obtain high yields of better quality tubers along with environmental protection (Pereira and Shock, 2006). ····· 10361147076

From the study of the effect of methionine, linoleic acid and supplemented fat in the diet it could be concluded that the levels of these components of commercial diets currently used in Spain, in the last part of the production cycle, can be reduced considerably without any effect on hen productivity and little effect on egg quality. In response to the influence of calcium level and source of the diet of laying hens it could be concluded that brown egg-laying hens late in the production cycle require more than 3.5% Ca in the diet (4.08 g Ca/d) to maintain productivity and shell quality. Also, the substitution of part of the fine limestone of the diet by coarse limestone or oyster shell does not affect productive performance and tibia characteristics although it might improve some shell quality traits. Regarding the influence of main cereal and mean particle size of the cereal in the diet of laying hens it could be concluded that both corn and hard wheat can be used indistinctly in diets for laying hens when ground to pass through a 6- to 10-mm screen. ····· 10361147047

The present study, attempts were made to find out the physiological, biochemical and molecular basis of resistant and stage specific immunity, against KB.The enzymes of phenylpropanoid pathway were expressed and remained higher in resistant genotype. Phenylpropanoid metabolism is involved in synthesis of carotenoid, act as precursor of ABA synthesis. The low carotenoid levels in resistant than susceptible genotype due to its more conversion in to ABA pool, induced downstream jasmonic acid mediated pathway and caused induction of PR- proteins (b-1,3 glucanase, protease and protease inhibitors) in wheat spikes. Stoichiometric balance of protease and protease inhibitor play key role in controlling the resistance by intervention of programmed cell death (PCD). The results of present study clearly demonstrated that resistant is due to involvement of multi component signaling leading to genotype to genotype dependent and stages dependent immunity against KB and cystatin-proteinase interaction is key factors in triggering plant defence against pathogenic fungi. ····· 10361146965

Attempts have been made from the colonial era to present time to introduce soil and water conservation measures in a wide range of agro ecological settings, yet many have failed. Being one of the drought prone and famine affected African countries, Ethiopia started a program of soil and water conservation measures on the highlands but the result was far less than expectation. The most influential factors for less adoption of physical soil and water conservation measures, besides socio-political and environmental factors, are land lost by physical soil and water conservation measures and low return from such conservation measures.
