A study was made on the effect of arsenic (As) and As X P interaction in Boro rice and its residual effect in succeeding T. Aman rice. Arsenic was added to soil (having 2.6 ppm initial As) @ 0, 15 and 30 mg As kg -1 from Na2HAsO4.7H2O and phosphorus @ 0, 20, 40, 60 and 80 mg P kg from KH2PO4. Each pot had received 100 ppm N, 40 ppm K and 25 ppm S from urea, MoP and gypsum, respectively. The gra...

This study investigated the influence of nitrogen (N) fertilizer and straw on intact amino acid N uptake by soil microorganisms and the relationship between amino acid turnover and soil properties during the wheat growing season. A wheat pot experiment was carried out with three treatments: control (CK), N fertilizer (NF) and N fertilizer plus rice straw (NS). We used stable isotope compound-sp...

For characterization of the ability of crops to reflect changing soil properties after the addition of ameliorative materials into the soil both pot and rhizobox experiments were provided. In the pot experiment, the influence of the addition of lime and limestone into contaminated Cambisol containing 7.14 mg Cd/kg, 2174 mg Pb/kg, and 270 mg Zn/kg on element availability for spring wheat was tes...

Two pot and two field experiments were conducted at Patuakhali Science and Technology University research farm to investigate the contribution of tidal submergence to phosphorus nutrition and yield of rice. Pot and field experiments were conducted in the Aus and Aman seasons of 2009, respectively. The factorial experiments include two levels of water sourcei) tidal water and ii) ground water, a...

allelopathic relationship between plant associations, could be applied in non-chemical ‎weed management, however, those allelochemicals should not have adverse effects on arable ‎crops. in order to evaluate allelopatic effects of barley (hordeum vulgare) on ‎germination & growth characteristics of lentil (lens esculenta), two experiments were ‎conducted based on compactly randomized design (crd...

Organic mulches, like peel and rice-straw, besides other materials affect the UV and temperature, which cause a reduction in the aphid arrival. The aim was to evaluate the effect of covering the soil with straw on the populations of the green peach aphid, Myzus persicae on the kale, Brassica oleracea var. acephala plants. The first experiment evaluated the direct effect of the rice-straw mulch ...

This study examines the effects of straw management and winter flooding on soil N dynamics and crop N uptake in California rice (Oryza sativa L.) systems. Experiments were established in two locations in northern California with main plot treatments being winter flooding or no flooding; and four straw management practices (burn, remove, incorporate, and roll) as subplot treatments. Fertilizer w...

Crown gall disease caused by Agrobacterium tumefaciens is considered as the main bacterial disease of stone fruit rootstocks in Tunisia against which only prophylactic control measures are available. Therefore, twelve rhizobacterial strains and two reference antagonists Agrobacterium rhizogenes K84 and K1026 were investigated for their efficacy against the causal agent of the disease in vitro, ...

BACKGROUND Straw is one of the most effective rooting materials to reduce tail biting in pigs. A so-called foraging-tower (FT) provides only small quantities of straw compatible with liquid manure systems. The focus of the present study was on the effect of providing straw by FT in order to prevent tail biting in tail docked pigs. Four consecutive batches of 160 pigs, randomly divided into a st...

The aims of the present study were to determine the effect of rearing environment on the productivity and physiological indicator during the nursery phase of pigs. 14 litters of commercial crossbred pigs (Large White×Landrace) Weaned at 35 days of age were reared in their original pen with the weaker eliminated. 7 flatdecks (F) and 7 straw enriched pens (S) were modified from the farrowing pen....
