The results of diallel analysis of 7 parents and 21 F2 progenies of Burley tobacco cultivars, which were transplanted in 2002 as RCBD with 3 replications in the Tobacco Research Center, Rasht, Iran, showed significant genetic differences among genotypes and high GCA and SCA for most of the traits. Therefore the role of additive and non-additive (dominant) effects of genes on the formation of th...

Rice-rice system and rice fallows are no longer productive in Southeast Asia. Crop and varietal diversification of the rice based cropping systems may improve the productivity and profitability of the systems. Diversification is also a viable option to mitigate the risk of climate change. In Eastern India, farmers cultivate rice during rainy season (June-September) and land leftovers fallow aft...

In the semi-arid tropics, over two-third’s of the world’s people depend on agriculture within which livestock play a major role in building rural livelihoods. Crop residues (fodder/stover) are important feed resources for ruminants. This review was undertaken with the objective of improving understanding of the role of various crop management factors in affecting the productivity and quality of...

Earthworms are essential detritus feeders that play a vital role in the process of decomposition of organic matter and soil metabolism. They are referred to as indicators of soil health. The complex process of partial breakdown of organic matter and mixing with mucous and gut microbial flora in the form of earthworm cast results in the enhancement of soil fertility status. They influence the so...

  In order to reduce the herbicide rate, the combination of cultivation and eradicane herbicide application was tested under field conditions. Treatments including tillage practices of without cultivation, one cultivation and two cultivation and eradicane herbicide application levels of 0, 1.5, 3, 4.5, 6 Lha -1 were tested . Eradicane herbicide was used before plantation. Cultivation treatments...
