a field experiment was conducted to study the physical properties of maize grain in response to different urea fertilization methods (urea foliar spraying and soil application), three harvest times (grain moisture content of 20, 30 and 40 pecent) in four maize hybrids (three foreign hybrids e.g. ns640, jeta600 , konsur580 and one common hybrid, sc704 as control) at khorram abad agricultural res...

Since the introduction of LLE (Roweis and Saul, 2000) and Isomap (Tenenbaum et al., 2000), a large number of non-linear dimensionality reduction techniques (manifold learners) have been proposed. Many of these non-linear techniques can be viewed as instantiations of Kernel PCA; they employ a cleverly designed kernel matrix that preserves local data structure in the “feature space” (Bengio et al...

The goal of blind text image deblurring is to obtain a clean from the given blurry without knowing blur kernel. Sparsity-based methods have been shown their effectiveness in various models. However, kernel estimation based on sparse priors lack consideration for brightness information about kernel, which will affect restoration effect Besides, previous seldom apply both spatial domain and trans...

Kernel starch content is an important trait in maize (Zea mays L.) as it accounts for 65-75% of the dry kernel weight and positively correlates with seed yield. A number of starch synthesis-related genes have been identified in maize in recent years. However, many loci underlying variation in starch content among maize inbred lines still remain to be identified. The current study is a genome-wi...

This study was conducted to determine the dietary effect of graded levels unripe plantain peel meal on growth performance and internal organs broiler chickens. One hundred five (105) day-old unsexed Arbor Acre chicks were used in a56-day feeding trial. The birds assigned 5 treatments (T1- T5) with a total 21 per treatment replicated three times 7 replicate completely randomized design (CRD). T1...

self pollinated cultivars of hazelnut are limited mainly due to dichogamy and self- incompability. to enhance productivity of hazelnut orchards, identification and selection of suitable polinizers are necessary. to meet this quest, collection and evaluation of iranian hazelnut germplasm have began by department of horticulture research, seed and plant improvement institute, iran, since 1994. ha...

most of hazelnut orchards in iran have been established by planting native genotypes. to enhance productivity of these orchards, adapted and high yielding hazelnut cultivars are to be developed and released. to meet this quest, collection and evaluation of iranian hazelnut germplasm have began by horticultural crops research department, seed and plant improvement institute, iran, since 1994. ha...

The objective of this research was to investigate physicochemical and biochemical characteristics of fieldsprouted grain sorghum and its fermentation performance in ethanol production. Five field-sprouted grain sorghum varieties, which received abnormally high rainfall during harvest, were used in this study. Enzyme activities, microstructure, flour pasting properties, kernel hardness, kernel w...
