The differential weed-competitive abilities of eight rice genotypes and the traits that may confer such attributes were investigated under partial weedy and weed-free conditions in naturally occurring weed flora in dry direct-seeded rice during the rainy seasons of 2011 and 2012 at Ludhiana, Punjab, India. The results showed genotypic differences in competitiveness against weeds. In weed-free p...

Cropping intensification has led to yield declines, compacted and poor quality soil, and increased pest problems. Cover crops in the Brassica (mustard) family offer benefits in soil conservation, improvement in soil quality, reduction in nitrate leaching, and suppres...

The biological effect of white fluorescent light exposure (emitted from an ordinary 30 Watt, 220V fluorescent bare lamp) on the anatomical architecture of Phaseolus vulgaris L.plants obtained from pre-treated seeds was obtained . Both soaked and dry seed lots were separately exposed to light source for 1, 2, 3 & 4 discontinuous periods of one hour with a break time of a complete hr. between eac...
