Growth characteristics of Cannabis saliva L. are indispensable factors to verify the statements by the criminals of illegal cannabis cultivation. To investigate growth characteristics of C. sativa, two varieties, cannabidiolic acid (CBDA)-rich (CBDA-type) which being cultivated for fiber production and delta9-tetrahydrocannabinolic acid (THCA)-rich (THCA-type) which is used for drug abuse, were...

> Sowing crops following cover crops on forage may cause injuries andproductivity reduction, due reasons as allelopathy or glyphosate residues. Theobjective of this study was to evaluate the influence of differing periods betweencover crop (Urochloa ruziziensis) desiccation with glyphosate and sunflower(Aguará 4) sowing in a no-tillage system on crop development and productivity.Two assays were...

In present investigation, the seeds of Helianthus annuus L. variety Modern were treated with nine different concentrations (0.05%, 0.25%, 0.50%, 0.75%, 1.00%, 1.25%, 1.50%, 1.75% and 2.00%) of caffeine to raise the M1 generation and the effect of caffeine on seedling height on 30 th day of sowing, mature plant height, days to maturity and yield parameters was observed. Generally, the lower dose...

The objectives of this study were to evaluate the effects splitting application 30 kg N ha-1 on growth, yield and economics soybean (Glycine max var. Dea-won) in semi-arid sub-tropical Afghanistan. Besides no-N-fertilization control, urea (30 ha-1) was applied fields four-splits: S1, one time basal at sowing; S2, two-splits 50% sowing 10 DAS (days after sowing); S3, three-splits 33% sowing, 20 ...

ABSTRACT Spontaneous plants in vegetable growing areas significantly impact yield and costs, regardless of the adopted cultivation system. This study aimed to evaluate weed interference periods on profitability organic carrot under different sowing methods. Two experiments were set up [weed control coexistence, a randomized block design arranged as split plots (5 × 2), with five periods: 15, 20...

The germination percentage of Acacia catechu Willd. seeds were tested with four pre-sowing treatments in the nursery of Bangladesh Forest Research Institute and growth performances of seedlings were determined both in nursery and field conditions. The germination test was conducted both in germination tray and nursery bed filled with mixture of soil and decomposed cow dung at a ratio of 3:1. Th...
