Maize, (Zea mays L.) is the third most important cereal food crop consumed by the world"s population after wheat and rice. It is a versatile crop grown under different agroclimatic conditions.Owing to its genetic yield potential maize is referred as "queen of cereals". It is grown throughout the year in all the seasons in India but predominantly grown as a kharif crop and accounts approximately 9 percent of the total food grain production of the country. Maize plays an important role in Indian economy, besides being a potential food source, it is also used as a fodder crop, cattle feed, poultry feed and industrial purposes such as glucose and starch production.Water is the elixir of life, and is the most important input in agriculture. When the soil water is insufficient and results in lack of crop growth and production is referred to as drought. Drought is the major stress that compromises the yield around the world
The insect pests and diseases of blackgram continue to pose a serious threat to the plant growth and yield. The sucking pests in blackgram are economically most important that not only cause the direct damage by feeding but also by transmission of different viral diseases. Sucking pest complex in blackgram include an array of sucking pests out of which thrips, whitefly and aphids are the most important. The leaf curl disease caused by GBNV in blackgram is transmitted through thrips. A study was conducted involving 25 blackgram genotypes to screen them against leaf curl disease. The results obtained from the study indicated that the leaf curl disease incidence (%) and thrips population (Number plant -1 ) varied significantly among the genotypes. Late sowing of the crop coincided with higher temperatures, lower relative humidity and high vector population resulting in higher leaf curl disease incidence. The correlation studies indicated that the leaf curl disease incidence (%) was negatively associated with the mean and morning relative humidity (%) and positively associated with mean, maximum and minimum temperatures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
