Net assimilation rate (NAR) increased with nitrogen content per unit leaf area (C), but further increase in leaf nitrogen caused diminishing returns of NAR Optimal nitrogen content per unit leaf area (Copt) to maximize dry-matter production of a leaf could be determined by drawing a tangent from the ongin to a curvilinear relation between NAR and C. This optimal content divides a nitrogen-limiting range (C < Copt) from a carbon-limiting one (C> Copt) along the axis of nitrogen content. Animal component existed in 60% of the sampled households that included cattle (cows and goats), pigs, poultry and birds (hens and ducks).

Top of document DEFINITIONS Alley Cropping: Growing annual crops between rows of trees or shrubs. Productivity: most, if not all, Agroforestry systems aim to maintain or increase production (of preferred commodities) as well as productivity (of the land). In the UK, traditional agroforestry systems include wood pastures such as the New Forest, browsing of acorns and beech mast (pannage), parklands, orchard grazing and hedgerows. Nitrogen availability influenced nitrogen uptake of plants through the uptake rate per unit root weight rather than the amount of root. Thampan P.K. This diversification of the farming system initiates an agroecological succession, like that in natural ecosystems, and so starts a chain of events that enhance the functionality and sustainability of the farming system.

Apart from distinct differences in clean bole length, crown depth, maximum crown width and leaf area index (LAI), the ES species showed higher allocation to the shoot, particularly to the bole, whereas the LS species had higher allocation to the root. of dry matter and nitrogen among organs. The implication of these results for agroforestry and mixed plantation forestry is emphasized. Ponds as a component of homegardens were observed in 11% of the homesteads whereas only animals in pond ecosystem of the homegarden were observed in only 2% of the household. The study reported species diversity, size and component arrangement in randomly selected 100 homegardens from north Bengal. Additionally, the company founded a plantation in 2012, which has set up an agroforestry system. The ES species with shallow root system had more root biomass within the upper 20 cm of the soil profile while the LS species with deeper roots had a higher proportion of root biomass distributed below the 20 cm depth. Using regressions of the parameters on leaf nitrogen, a model of leaf photosynthesis was constructed which gave the relationships between leaf nitrogen, photon flux density (PFD) and photosynthesis. h�b```f``Z������� € ",@Q� `.ӲWlk�6|f�h`�Ǡc���!I��(Y�ʢ- ��QP?m�B!�]ߔ�tL�$�j������9f ƝȍT�$�ήpq�� �����������,,�@��I����(#��g3(0�H�Ң@,v�&�0�� �u� �.��g�Xe++dX�X"��:�����M2���l/u!f*3�D��b``�Ux,��x�>AT1v x�I� major agroforestry systems in the tropics and the recent developments in each of them are discussed in Section II (Chapters 3-10). and particular .

Evaluate the ways of learning by and about … Hydromorphic agroforestry system: It referes to agroforestry in the wet lands or in waterlogged areas, e.g., acquaforestry, paddy cultivation with fish culture. Accelerated root growth was observed only in plants which earlier had received high levels of nitrogen. Measurements show that dense leaf canopies transmit very little radiation in the wavelengths 400-700 nm and many times as much radiation in the longer wavelengths.It is shown that germination of seeds requiring either light or darkness can be inhibited under a dense canopy but the ecological importance of this phenomenon is not proved. Forests Types of India Page. In: TREES AND TREE FARMING. Learning Objective Page. Productive Agroforestry system: this system refers to the production of essential commodities, req uired to meet the bas ic needs of the society.
