Four semi-dwarf rices (Oryza sativa L.) differing in percentage of grain protein, grown in a flooded field receiving basal N fertilization, had a peak activity of root glutamate dehydrogenase 4 weeks after transplanting. A lower peak occurred during panicle formation 10 weeks after transplanting. The percentage of N of the active leaf blades was also highest 4 weeks after transplanting. The act...

Increase in rice yield under excessive nitrogen (N) supply is negligible, hence it is necessaryto analyze the limiting factors via yield components. The present study was carried out during2014 and 2015 growing seasons in order to quantify the yield componenents of different typesof tiller at various N levels. Tillers were divided into three different types (superior, mediumand inferior) based ...

five improved along with three local rice varieties were crossed in a line× tester method in 2001. fifteen f1 hybrids and eight parental genotypes were planted in a randomized complete block design with 3 replications at rice research institute of iran, rasht, in 2002. the main objective of the research was to estimate the general and specific combining ability and gene action for 10 agrnomic a...

this study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. the main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...
