Submit Manuscript | http://medcraveonline.com in its theoretical yield (470mt ha-1 year-1) and productivity achieved at field (168 mt ha-1year-1) with average cane yield hovering around 65 tonnes ha-1. In India, which is second largest sugarcane producer in the world after Brazil, this productivity lingers around 28 % of the theoretical maximum. The prevalence of short duration crop cultivation...

The objectives of this research were to characterize dry period lengths for US Jerseys, determine the effects of days dry (DD) on subsequent lactation actual milk, fat, and protein yields, fat and protein percentages, somatic cell score (SCS), and days open (DO), and to determine the dry period length that maximizes yield across lactations. Field data, collected through the Dairy Herd Improveme...

Manufacturing performances tend to produce defects due to various reasons which can be improved by identifying and eliminating them using six sigma. In the present work, DMAIC (Define, Measure, Analyze, Improve and Control) has been used to reduce the number of vehicle engine rejection. In define phase problem was defined by selecting the core issues concerned. In the measure phase data was col...

The adaptive responses of crop genotypes and patterns of genotype x location (G x L) interaction are important to crop improvement as they are the basis for selection for specific adaptation and for elucidation of the causes of G x L interaction. Their legitimate assessment, however, requires yield data for the test genotypes for a large number of sites and over multiple years. Such data are se...

­­Drought is one of the most destructive abiotic stresses worldwide that affects growth, development and final yield of crops. Reactions of thirteen rainfed spring 2-row barley genotypes and cultivars of cold areas of Iran to water stress were evaluated based on phenological, physiological and morphological traits. The experiment was carried out as factorial experiment based on a randomized com...

Temperature and CO2 are two important parameters related to climate change, which affect crop yield. In this study, an attempt has been made to assess the impact of these two factors on the productivity of the four major cereal food crops (wheat, rice, maize and pearl millet) taking New Delhi as study area. This study also aims at identifying the most sensitive growth phase of these crops to th...

Two major difficulties exist in the use of Aspergillus niger v. Tiegh for identification and study of the roles of micronutrients, although these are certainly not unique with this fungus. The water, sucrose, and salts employed may be assumed never to be completely free from impurities of micronutrients. Moreover, increases in yield with apparently non-nutritive elements may be due to biologica...

Microscopic bud dissection can be used to assess grapevine fruitfulness prior winter pruning and long before actual measured in the vineyard following spring. Bud dissections should performed by qualified trained personnel because inflorescence primordia are difficult distinguish some varieties. In Puglia region, Southeastern Italy, 2018 2019, potential using observed were compared for seventee...
