The treatments were nutrient solution free nitrogen (N), nutrient solution free phosphorus (P), nutrient solution free potassium (K), nutrient solution free PK, nutrient solution free PN, nutrient solution free NK, nutrient solution free NPK and nutrient solution with NPK. Root dry weight (RDW), Shoot dry weight (SDW), RDW/SDW, leaf number (LN), leaf area (LA) and chlorophyll content were determined. Results showed that the highest LA (561 cm2), SDW (22 g) were obtained in with NPK treatment and KWS2360 hybrid while Ressuda Pionee in NPK treatment had highest RDW (3.8 g) and LN (5.6). The highest R/S obtained in free NP treatment and KWS2360 hybrid (1.1). The lowest LA (45cm2) and LN (3.0) were obtained in free NK treatment. The lowest RDW (0.12 g) and SDW (0.31g) were obtained in free NPK treatment. The treatment of without NPK and KWS2360 showed the lowest R/S (0.16). Chlorophyll content of each leaf decreased in through time. Slope of curve was higher in without NPK, NK and NP treatment compare to with NPK treatment. Hybrids of corn in with NPK treatment had longer growth period compare to other treatments. KWS2360 hybrid showed better performance under nutrient stress. Overall, it can be said that the balance in the ratio of nutrients plays an important role in increasing the vegetative growth of plants including corn and deficiency of each macro nutrients can be a factor in reducing the growth of this plant.","PeriodicalId":287764,"journal":{"name":"Journal of Agroecology","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115739220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vermicompost, as an end product of urban waste recycling with proper physicochemical features, can play an effective role in plant growth and development and also in reducing harmful effects of various environmental stresses on plants. For this purpose, a study with the aim of investigating the effects of vermicompost and salinity interactions on morphological traits of bean (Phaseolus vulgaris L. cv. Light Red Kidney) seedlings was performed. The experiment was conducted based on a randomized complete block design, including five different volumetric ratios of vermicompost and sand (0:100; 10:90; 25:75; 50:50 and 75:25), and four levels of salinity (30, 60, 90 and 120 mmol l-1 NaCl), equal to 2.75, 5.50, 8.25 and 11 deciSiemens per meter (dS/m) respectively, along with control (0.00), in three replications. Seeds were cultured in plastic pots and sampling of seedlings was done after 28 days. The results showed that in an environment without stress, vermicompost had significant effect (p ≤ 0.05) on the stem length, internodes number, area and dry weight of leaves, diameter, dry weight and total roots length, while having no significant effect on stem dry weight. The interaction between salinity and vermicompost has significant effect on the stem length, internodes number, the area and dry weight of leaves and dry weight of roots but no significant effect was observed on the stem dry weight, diameter and total roots length. Thus, in the low levels of salinity, all ratios of vermicompost and in high levels of salinity, high ratios of vermicompost can limit the negative effects of salinity on bean seedlings.","PeriodicalId":287764,"journal":{"name":"Journal of Agroecology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129241470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental design was split plot based on randomized complete block design (RCBD) with three replications. The emergence time was considered in three levels: emergence of the weed 14 days earlier, 7 days earlier and concurrent with corn, respectively, as main plots and density of weed at six levels: 0, 4, 8, 12, 16 and 20 plants per m2, respectively, as subplots. Plant height, leaf area index (LAI) and dry matter (DM) of corn decreased with earlier emerging and increasing density of the common lambsquarters. In contrast, LAI and dry matter of common lambsquarters increased with earlier emerging especially at high densities. Though, the increase in density of the weed resulted in reducing measured characteristics, but there was no difference between the processes of reduction in high densities of weed.

Treatments including two low input management systems based on application of cow manure and compost municipal made from house-hold waste, a medium input system and a high input system. Application of inputs and management practices were based on a basic assumption made prior to the start of the experiment. On the other words, for each of the management system the particular set of inputs were allocated. In this respect, for low input system 30 t.ha-1 cow manure or 30 t.ha-1 compost municipal made from house-hold waste, twice hand weeding were used. In medium management system, 15 t.ha-1 compost municipal made from house-hold waste, 150 kg.ha-1 urea, two seed bed operations, 1.5 l.ha-1 2, 4-D herbicide applied at five-leaf stage and one time hand weeding were used. In high input system, the inputs were two seed bed operations, 2 l.ha-1 Paraquat herbicide used after seeding and 1.5 l.ha-1 2, 4-D applied at five-leaf stage. Results showed that the effect of different crop management practices on the shoot biomass, seed weight, root biomass, total biomass, shoot biomass: root biomass (S:R), SRL and HI were significant (p≥0.01). High input management system enhanced total biomass and S:R and decreased seed weight, root biomass and SRL. The highest and the lowest total biomass observed in high input (18.3 kg.m-2.yr-1) and low input with using compost (10.3 kg.m-2.yr-1), respectively. The maximum SRL observed in low input based on cow manure application (19.8 cm.cm-3 soil) and the minimum SRL was in high input (1.3 cm.cm-3 soil). Range of relative carbon allocation coefficients to seed, shoot, root and extra-root were estimated as 0.10-0.17, 0.19-0.52, 0.23-0.39 and 0.15-0.25, respectively. Low input with cow manure application increased allocated carbon to seed, root and extra-root and decreased allocated carbon to shoot. The highest allocated carbon to root observed in low input with using manure (6.5 g C m-2.yr-1) and the lowest allocated carbon to root was in high input (2.7 g C m-2.yr-1). The maximum and the minimum NPP were obtained in low input with cow manure application (16.6 g C m-2.yr-1) and high input (8.9 g C m-2.yr-1), respectively.
