ABSTRACT: Weeds reduce the productive potential of crops. Plants of the Ipomoea genus, besides competing for water, light, space and nutrients, create problems in crop harvests due to their volatile stems. The objective of this work was to evaluate the growth and development of five Ipomoea species. For such, Ipomoea grandifolia, Ipomoea hederifolia, Ipomoea nil, Ipomoea purpurea and Ipomoea quamoclit plants were analyzed during the summer and winter season. Five destructive and periodic growth evaluations were carried out for each study, where leaf number, leaves, stems, roots and the total biomass were analyzed. Phenological stages of the plant development were also evaluated for emergence, flowering and maturation sub-periods by degree-days, totalizing five treatments, conducted in a completely randomized design with four replicates. The phenology averages were analyzed according to the Hess scale, and the growth data through nonlinear regressions. I. quamoclit and I. grandifolia obtained the highest number of leaves in the summer and the winter, respectively. I. nil obtained greater accumulation of leaf and stem dry biomass in both seasons. I. grandifolia obtained greater root development in both periods. I. quamoclit presented reduced cycle times when compared to the other species, especially I. hederifolia and I. grandifolia, which presented larger cycles. Based on the results, I. grandifolia probably shows greater interference with agricultural crops due to high root growth, high leaf production and longer cycle. Shorter-cycle species, such as I. quamoclit, when present, should require shorter residual control periods.

Objective: The objective of this study was to evaluate the response of different concentrations of a fungal consortium on the growth and yield of Cenchrus purpureus ecotypes under storm conditions.Design/Methodology/Approach: An experiment was established under a completely randomized design with a 9X2X4 factorial arrangement. The factors were 9 ecotypes of Cenchrus purpureus, two seasons of the year (Summer-Fall and Winter-Spring), and four levels of mycorrhizal consortium. The variables evaluated were: number of buds, number of leaves, height of the bud, leaf length, total biomass, and leaf-stalk ratio.Results: The response of the ecotypes had a differential effect on the variables NB, LLL, TB and L/SR, while the season affected the variables LN, PH, LLL, MLL, SLL, TB and L/SR. Low inoculation levels increased the variables NB, PH, LLL, MLL and TB.Study Limitations/Implications: The evaluated factors indicate that the level of inoculant and the season determine the growth and yield of Cenchrus purpureus.Findings/Conclusions: The mycorrhizal consortium dose and season of the year mainly determined the growth and yield of C. purpureus. Ecotypes respond differently to changes in the season and in mycorrhizal consortium dose. The evaluated factors indicate that the mycorrhiza dose and the season of the year determine the growth and yield of C.purpureus. Two growth strategies of the ecotypes are visualized: 1) many buds, with few small leaves and 2) few buds with many large leaves

Effect On Growth

Controlled environment experiments were carried out to determine the effect of temperature and photoperiod on Astrebla pectinata, A. lappacea, A. elymoides, and A. squarrosa. Photoperiod had little effect on growth and development of tillers and on floral initiation, but did affect numbers of emergent inflorescences. Usually, inflorescence production increased with decreasing photoperiod. Temperature had significant effects on all parameters measured (number of main tillers and emergent inflorescences, elongation of main tillers, and number of leaves and axillary tillers per main tiller). Growth per tiller and leaf production increased with temperature (up to 30/25�C) but for tiller numbers the optimum was about 28/23�, Geographically separated strains of A. pectinata generally exhibited similar responses to photoperiod and temperature while different species from the same location differed in their response.

The Difference

A method used for the development of dry areas/marginal lands is the improvement of soil structure and addition to the media to support the growth and development of crops. Tomatoes have the potential to be developed in marginal lands due to its high nutrition, high in demand and easy to be cultivated. One of the method used to improve planting media is the addition of microorganism such as mycorrhiza which can help the absorbtion of water and nutrition for plants. The interval of irrigation is used as a simulation of drought. This research aim was to observe the effect of mycorrhiza in the soil on the growth and development of tomato with several treatments of irrigation. The method used was the addition of 4 g of mycorrhiza  per polybag (size 30x30 cm2), using Complete Randomized Design. There were 6 combinations of treatments. The treatments were : 3 interval of irrigation (every day, every 7 days and every 14 days), and 2 treatments of mycorrhiza (0 g and 4 g). There were 3 repetition for each combination of treatments. The results showed that the addition of mycorrhiza can increase significantly plant fresh and dry weight and also root length. The difference in plant height, number of branches, number of leaves, plant growth rate and percentage of infection were caused by the difference in irrigation interval. The difference in the varieties used also contribute to a difference in the percentage of infection. Further research must be made on the effect of mycorrhiza with addition of inorganic fertilizer to increase the growth and development of tomato plants in water stressed condition.

Objective: To evaluate, in a nursery, the effect of two controlled release fertilizers in three concentrations on the growth components and quality index in caracolillo seedlings. Design/Methodology/Approach: A factorial arrangement (2 x 3) housed in a completely randomized design was used, with seven treatments and twelve repetitions. For three months, the growth of caracolillo plants maintained in 310 cm3 polyethylene tubes, with a substrate of peat moss, vermiculite, agrolite and soil (2:1:1:1), plus controlled release fertilizer (CRF) Basacote® 9M (16-8-12) and Multicote® 12M (18-6-12), in three doses each: 10 (low), 20 (medium) and 30 kg m-3 (high), in addition to a control without conventional fertilization (CF) 17N-17P-17K in doses of 10 kg m-3. The variables height, diameter, leaf number, robustness index (RI), aerial/root dry biomass ratio (ADB/RDB R) and Dickson’s quality index (DQI) were measured. The means were compared by Tukey’s test at a 5% confidence level.  Results: Basacote® and Multicote® fertilizers in low doses allowed an adequate growth and development in caracolillo plants, which was reflected in the variables height, diameter and number of leaves. The RI and DQI indices presented values within the normal ranges, while those of ADB/RDB R were rather low, but in the three cases there were no statistical differences. Study Limitations/Implications: Based on the results obtained, it is recommended to continue monitoring the studied plants in the field, which would allow adjustments in the initial fertilization doses. Findings/Conclusions: The low doses (10 kg m-3) of the controlled release fertilizers Basacote® and Multicote® showed the best results in the growth and development of caracolillo in the nursery stage, but the RI, ADB/RDB R and DQI indices did not present statistical differences.

Influence of urea fertilizer on early growth and development of Pterocarpus erinaceous seedlings were investigated. Two hundred (200) uniformly growing seedlings were transplanted into polythene pots filled with top soil. Four urea fertilizer rates (0.035; 0.065; 0.095; 0.0125 g) and control were applied to the seedlings in the pots 20 × 25 × 25 cm, filled with 800 g of top soil collected from forest plantation. Assessment on the metrical character of the seedlings was done fortnightly. The fertilization of the selected seedlings with urea fertilizer was done round the seedlings in the nursery pots using ring method. The experiment was laid out in a completely randomized design. The data were subjected to analysis of variance, and means were separated using Duncan’s multiple range test at p < 0.05. The results show that fertilizer rates had significant (p < 0.05) effect on the growth and development of seedlings of P. erinaceous. Seedlings treated with 0.095 g of urea produced the highest mean values of 12.00 ± 0.66 cm; 0.33 ± 0.01 mm; 190 cm2 and 12.65 ± 0.67 for stem height, collar diameter, leaf area (LA) and number of leaves respectively. Seedlings fed with 0.125 g had the lowest values of 11.19 ± 0.61cm for height, 0.32± 0.01 mm for collar diameter 11.54 ± 0.70 for number of leaves and 124 cm2 for the LA. Urea fertilizers had significant effect on the early growth of the seedlings, therefore fertilization at 0.095 g per pot is recommended for raising P. erinaceous seedlings.
