Preplant soil applications of oxamyl to shade grown tobacco in Globodera tabacum-infested field soil increased green leaf yields over untreated plots by 10.7 and 21.0% for 2.2 and 6.7 kg a.i. oxamyl/ha, respectively. Green leaf yield was negatively correlated (r = -0.60, P = 0.04) with initial G. tabacum density, which ranged from 33 to 154 second-stage juveniles (J2)/cm(3) soil. Numbers of G. ...

In recent years leaf curl disease of cotton has become a major limiting factor in the production of cotton, which is an important fiber cash crop. In the last two decades or more, leaf curl disease in cotton took on epidemic proportions in Pakistan. In the early 1990’s cotton leaf curl disease (CLCuD) appeared in the bordering parts of India in the states of Rajasthan and Punjab and spread to e...

carbohydrate flow between vegetative and reproductive parts of trees is one of the determining factors of yield and fruit quality. therefore, it varies during different times of growth season. the aim of this study was to investigate the carbohydrate content variation during growth season between leaf and fruit of nectarine. so, eight nectarine trees cv. red gold selected randomly in the orchar...

activity of fresh neem leaf juice to immobilize, anaesthetize and fatal effect were studied against two live fish species, anabas testudineus and channa punctatus. the concentrations, 5, 10, 15 and 20% of neem leaf juice affected both the species, but a.  testudineus was found to be comparatively more susceptible to the treatment  than c.  punctatus . the time required to immobilize were 4 to >...

Agrobacterium tumefaciens B-6 and T-37 strains, inoculated into Nicotiana glauca, N. langsdorffii, and their interspecific hybrid, which forms genetic (spontaneous) tumors as well, initiate amorphous tumors from the B-6 strain and organoid tumors (aberrant roots, stems, and buds) from the T-37 strain. In the hybrid, the critical point was to induce crown gall tumors at the site of wounding and ...

in order to evaluate the effect of freezing stress on safflower (carthamus tinctorius l.) genotypes, an experiment was conducted in faculty of agriculture, ferdowsi university of mashhad, iran. treatments included 6 genotypes (k.w.3, k.w.6, k.w.16, zarghan 279, line 295 and il-111) and freezing temperatures (0, -4, -8, -12, -16 and -20 ˚c). the trial was arranged as factorial based on completel...

the objective of this work was to study the responses of two baby lettuce (lactuca sativa l.) cultivars, namely, green paris island and red sanguine, to different nacl concentrations (0, 5, 10, and 20 mm). the study was conducted in a floating system and plants were harvested at the stage of 5-6 leaves, outside leaf 6-10 cm in length (25 and 31 days after sowing for green and red lettuce, respe...
