Yield gaps have become a useful tool for guiding development-related agronomy, especially in the global South. The main proportion of the total yield gap was caused by water deficit (about 89 t ha-1, representing 73% of the total), followed by sub-optimal crop management (about 35 t ha-1, representing 27% of the total). One can calculate the DPS by dividing the total dividend by total outstanding shares.On the other hand, the yield on a bond is the return that an investor gets by investing in bonds. The yield gap analysis shows that 61%, 55% and 46% of wheat yield gap existed when the national average yield was compared with that of the actual yield at research station, farmers’ plot and potential yield at highland part of the country, respectively. So far it produces only 44% of the potential calorie production while irrigated farming has … Typically equities have a higher yield (as a percentage of the market price of the equity) thus reflecting the higher risk of holding an equity. Systems analysis and crop growth simulation mod-elling … Our agronomically robust yield gap analysis for 10 countries in SSA using location-specific data and a spatial upscaling approach reveals that, in addition to yield gap closure, other more complex and uncertain components of intensification are also needed, i.e., The yield gap analysis is an important tool to estimate to what extent the production could be increased if all factors are controlled. and the average dividend yield on stock shares. The second challenge in this endeavor is the Based on this analysis, we identify the key components and associated uncertainties of a global protocol for yield gap analysis to produce locally relevant outcomes that can be aggregated to regional or national estimates. published local and global yield gaps. The results show that the mean technical efficiency of the overall sample is 0.769 meaning about 23% technical inefficiency in the system implying that the sample wheat producers are producing at a yield gap of 659 kg/ha. reveals how this gap is shaped. NW-Europe), regions with humid tropical climates, and crops more susceptible to pests and diseases are all expected to have a larger organic yield gap. They found that labour use differences at plot level and variety types are main exponents of the yield gap. However, it is often difficult to estimate the attainable yields … The yield gaps were calculated as follows: YGE = Experimental station yield - Common-farmer actual yields (1) YGM = Model-farmer yield - Common-farmer actual yields (2) For the analysis of factors influencing yield gap, both types of yield gap were Downloaded by [Ghulam Murtaza] at 22:33 18 April 2015 converted into a 0–100 transformation, termed as yield-gap index (YGI), such that the higher the YGI the wider the yield gap … Globally, rain-fed farming covers 74% of cultivated land. It aims at identifying major yield constraints and at defining quantified Here, we attempt to clarify the definition of yield gap and the various methods used to estimate it. Ù[¾I9pHÛȼíÛsžr‘¬S™™S %lu®=Ä=0 You can download the paper by clicking the button above. Yield gap analysis, in which attainable yields without nutrient and water limitations are compared with actual yields, can iden-tify how much yield increase can be expected by alleviating these constraints. Van Ittersum & Rabbinge, 1997 The latter consist of the simulation of the water-limited yield of a crop for a certain climate and soil, to be used as reference yield to estimate the yield gap, and of the effect of management factors to explore possible yield gains (e.g. The yield gap therefore depends on the region and crop type: regions with more intensive, high-yielding production systems (e.g. Yield gap analysis of wheat-maize double cropping and its components 27 in the Hebei plain of China. of Agril Chemistary & Soil Large spatial and temporal variability was observed in the yield gaps of the four legumes across the production zones. Yield gap analysis of rapeseed-mustard through front line demonstrations in agro climatic zone IVa of Rajasthan BL Meena*, RP Meena, RH Meena1 and CM Balai2 Krishi Vigyan Kendra, Distt.- Rajsamand (Raj.) The empirical analysis found there is What is Yield Gap? Yield gap analysis of adopted and non-adopted pomegranate orchards in 2009-10 30 30 30 8.83 Gap Analysis Definition: Gap Analysis can be understood as a strategic tool used for analyzing the gap between the target and anticipated results, by assessing the extent of the task and the ways, in which gap might be bridged.It involves making a comparison of the present performance level of the entity or business unit with that of standard established previously. Yield Predictions: Conventional vs. Aimulation Approach. Definition The yield gap is a concept that rests on the definition and measurement of yield poten-tial. Six genotypes, two each for indica inbred, indica/indica F 1 hybrid, and the second‐generation new plant type, were grown in DS and WS of 2003 and 2004. Yield gap analysis of adopted and non-adopted pomegranate orchards in 2008-09 30 30 30 9.41 7.6 11.12 5.75 3.07 9.34 0 5 10 15 20 25 30 35 Maharashtra Karnataka Andhra Pradesh Yield (tonnes/ha) Potential Yield IDIPM Schedule Farmer's Practice. These bond issuers create bonds to borrow funds from bondholders, to be repaid at maturity. Concepts Yield potential (Yp), also called potential yield, is the yield 2. The yield gap analysis provides quantitative estimates of the production constraints for a number of crops and regions and reveals the difficulty to measure and compare yield potentials and actual yields consistently under a range of environmental conditions, and it shows the difficulty to disentangle interacting production constraints. Yield Gap Analysis of Crops in South and South-east Asia Yield gap analysis of rainfed crops in India By 2025, India’s population is expected to On the other hand, a study conducted in Vietnam attributed the yield gap between male- and female-headed households to be man-ifestations of endowment variations and their returns fluctuations [13]. Affholder, 1995, Rockström and Falkenmark, 2000, Bhatia et al., 2008). The Yield Gap is the difference between the yields of government-issued securities Bond Issuers There are different types of bond issuers. Assessment of the factors influencing yield gap In order to study the relationship between the ' factors contributing to yield gap … This study aimed to (i) compare the grain yield of rice in dry season (DS) and wet season (WS) and (ii) determine climatic and physiological factors critical to the yield gap between DS and WS. Production ecological principles YIELD GAP eg. According to the average yield gap in Paddy in India. Yields are potential, calculated with models; experimental, measured in researcher designed trials in growers’ fields, and maximum, average and minimum yield from surveys. Dividend yield, one can calculate by dividing Dividend per Share (DPS) by the market value of the share. Where multiple cropping is prevalent, yield gap analysis should target the system and its components; Section 4.1.4 presents an example of gap analysis in wheat-maize double crops in China. The differences between these theoretical yield levels and actual farmers' yields define the yield gaps, and precise spatially explicit knowledge about these yield gaps is essential to guide sustainable intensification of agriculture. The yield gap of a crop grown in a certain location and cropping system is defined as the difference between the yield under optimum management and the average yield achieved by farmers. While critics have challenged some aspects of the yield gap methodology, and the relevance of food security advocacy based on yield gaps, very few studies question the actual relevance, application and scalability of yield gaps for smallholder farmers (and researchers) in the … The yield gap analysis in the Hebei plain of China development-related agronomy, especially in the global....
