Chickpea (Cicer arietinum L.) is a native crop of Asia which is grown worldwide including Iran.In this study,different selection criteria including correlation,regression and path analysis were used to improve yield.The experimental design was split plot with RCBD replicated four times in which three sowing dates (5 January,4 February,and 5 March) were used in main plots and four genotypes;two ...

Leaf area index, defined as one half the total (all sided) leaf area per unit ground surface area [1], is a key vegetation structural parameter used in most ecological, hydrological and meteorological models to describe physical and biological processes associated with vegetated surfaces and their interaction with the atmosphere. The accuracy of existing global LAI parameters is not yet satisfa...

The quick and accurate acquisition of crop growth parameters on a large scale is important for agricultural management and food security. The combination of photographic and wireless sensor network (WSN) techniques can be used to collect agricultural information, such as leaf area index (LAI), over long distances and in real time. Such acquisition not only provides farmers with photographs of c...

Leaf area index (LAI) is a key biophysical variable in most process-based forest-ecosystem models. However, most such models require LAI as an input, typically obtained from empirical observations. We tested whether scaling principles based on trade-offs between single leaf and canopy properties could be effectively used to model LAI, thereby obviating the need for empirical observations. To do...

Hot pepper (Capsicum annum L.) is the most widely cultivated and economically important crop. However, its production productivities are constrained by different factors in which Cultivar fertilizer level major ones. Thus, experiment was conducted on two hot cultivars (Melka Shote Melka Awaze) six rates NPSZn + urea; to determine growth yield response of levels urea interaction effect both fact...
