It was usually established on a certain arable land. This study was conducted to determine the ability of various teak clones in the sprouting hedge garden which was established in the nursery. The study was arranged in randomized complete block design with 10 clones, 3 replications, and 10 individual ramet per replication. The tested clones were selected from a teak clonal test in Gunungkidul, Yogyakarta. The results showed that clones significantly affected the shoot growth: number, length, diameter, number of internode and number of leaf. At 6 weeks after hedging, the average of shoot number was 4.3, shoot length of 9.1 cm, shoot diameter of 5.9 mm, the number of internode of 2.4, and the average number of leaves was 5.1. The survival rate of plants after hedging treatment was varied from 86.7 to 96.7 %. Estimated heritability for shoot growth was categorized as moderate to high, varying from 0.41 to 0.73.

Flooding is the most important abiotic stress in the tropical and subtropical regions that negatively affects terrestrial plant growth and productivity and even leading to plant death. Amino acid accumulation, on the other hand, may serve as defense during stress resulting to tolerance among others. Thus, a study was conducted to determine the growth, root length and number of leaves produced by Philippine native tomato as affected by different levels of amino acid under varying durations of flooding. Data were statistically analyzed through Analysis of Variance (ANOVA) for Randomized Complete Block Design (RCBD). Comparisons among means were done using Duncan’s Multiple Range Test (DMRT). Shoot growth was increased with application of amino acids (100 ppm) after both flooding conditions (three and six days) at 3.28cm and 7.47cm, respectively. Moreover, no amino acid application or minimal amino acid application (100 ppm) produced the most number of leaves on unflooded and minimally flooded conditions (three days only). On root length, longer roots were produced by plants without amino acid (12.68 cm) or lesser amino acid (100 ppm) at 9.43 cm, while flooding had no significant effect on root length. These results clearly indicate the value of exogenous amino acid (100 ppm) application mainly on shoot growth of tomato. Furthermore, exogenous amino acid application is deemed necessary because even in both number of leaves and root length where results are comparable to without amino acid application, no negative effect was observed.   Keywords - agriculture, flooding, amino acid, Philippine native tomato

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.

Field experiment was carried out during 2010 rainy season to find the effect of seeding rate on the growth and yield of okra (Abelmuschus esculentus) in Zuru Northern Guinea Savannah. Zuru is located in Zuru Local government area of Kebbi State (Latitude 11o 251 to 11o 551 North and Longitude 4o 51 to 5o 251 East of the equator). The experiment consisted of three treatments that is planting okra at one plant per stand (S1), two plants per stand (S2) and three plants per stand (S3). The experiment was laid out in randomized complete block design (RCBD) and the treatments replicated three time. The result of the experiment has shown that plant height and number of leaves/plant at 3, 6 and 9 weeks after planting (    WAP) were significantly influenced by seeding rate (P<0.05). At 3, 6 and 9 WAP tallest plants were obtained from okra plants planted at three plants/stand (27.83, 54.0 and 77.0cm) respectively followed by okra planted at two plant/stand (24.77, 50.67 and 74.33 leave/plant respectively ). However, more number of leaves/plant were obtained from okra plant at one plant/stand (9.67, 24.67 and 48.0 leaves/plant respectively) followed by okra planted at two plants/stand (8.33, 18.33 and 36.33 leaves/plant respectively). Seeding rate had significant influence on time of 50 percent flowering with one plant/stand first attaining 50 percent flowering stage just within 36.33 days followed by okra planted at two plants/stand (38 days). The mean fresh fruit yield of okra was also significantly influenced by seeding rate with the highest yield of fresh fruits obtained from three plants/stand (83.34/ha) followed by okra planted at two plants/stand (55.56/ha). However, the result of the findings recommends that, okra should be planted at two plants/stand for medium sized and marketable okra fresh fruits since at three plants/stand leads to the production of undersized fresh fruits which do not often attract customers. At one plant/stand, there seemed to be early fruiting and bigger sized fresh fruits but low total yield due to underutilization of land resource/space. Planting at one plant/stand should therefore be avoided

This study evaluates the growth performance of lettuce (Lactuca sativa L.) utilizing various fermented products as organic fertilizers. Growth performance is determined through the plant’s weight and leaves and significant differences in growth among various treatments: (a) fish trash, (b) scrap seaweeds, (c) kangkong, and control groups urea (positive) and water (negative) was also determined. Kangkong leaves are fermented for 10 days, fish trash for 14 days and 1 month for seaweeds. Lettuce seeds are sown before transplanting (15 days after germination) into pots and placed in raised beds. Randomized complete block design is utilized in the experiment. Growth performance is measured through the number of leaves 10, 20, and 30 days after transplant and mass of plant upon harvest. After 30 days, the lettuce was harvested. Based on the findings, the soil and fermented products are acidic and the needed organic matter for optimum growth of lettuce are not sufficient as well as some nutrients of the fermented products. Among the organic fertilizers, kangkong at 30 ml performs best in terms of the growth performance of lettuce. Urea performs best in terms of the mass upon harvest. Significant differences exist in the mean number of leaves of lettuce treated with various amounts of organic fertilizers with the plants that receive urea. Lettuce produce more number of leaves and with the highest mass upon harvest when treated with urea compared with organic fertilizers applied after 30 days from transplant.

An experiment was conducted to assess the performance of sweet pepper varieties as influenced by nitrogen levels from August 2014 to February 2015 at Mangalpur, Chitwan. The experiment was laid out in two factorial Randomized Complete Block Design (RCBD) with three replications having sixteen treatments. Varieties and levels of nitrogen significantly affected growth, yield and qualitative parameters of fruits. Hybrid Indra and NS 632 performed better than open pollinated varieties viz. Sagar and California Wonder. Days to fifty percent flowering of NS 632 were earlier than California Wonder. Indra variety had the highest plant height (52.18 cm), number of secondary branches per plant (13.51) from 250 kg N/ha through chemical fertilizer while number of leaves per plant was higher in NS 632 variety (57.22) than Sagar variety (47.37). Indra variety showed the highest fruit weight (87.59 g) and total yield (39.45 t/ha) but NS 632 variety produced more number of fruits per plant (9.25) than California Wonder variety. This study showed that sweet pepper yield of hybrid varieties applied with 250 kg N/ha through chemical fertilizer was appropriate dose to get optimum yield under Chitwan condition.

The application of beads free of fungi and the substrate without an additive were the other treatments. The cuttings were rooted in vessels (60 cuttings per vessel, 180 per treatment) placed in a glasshouse and arranged in a randomized complete block design. The cuttings were estimated for one growing season (approximately for 26 weeks) after their insertion into the rooting substrate. Rooting % of the cuttings ranged from 45 (mycelium-free beads) to 75 (control) according to treatments, 64 on average. No significant differences among treatments were found in % of ECM morphotypes, total ECM colonization of roots (%), and growth parameters of shoots and roots of the cuttings. The applied microbial additives were not sufficiently efficient to form treatment-related ectomycorrhizas that were formed by naturally occurring ECM fungi. Inoculation by the ECM fungus Cortinarius sp. and application of Trichomil had a partial stimulative effect on the shoot growth of cuttings. Shoot and root growth parameters were not significantly correlated with total ECM colonization, except for a negative dependence of the root number in Trichomil treatment. A higher concentration of K but lower concentrations of Ca and Mg in Ectovit treatment than in the other treatments were detected.&nbsp; &nbsp;

The lack of research about escarole cultivars adapted to each region, as well as technical information on plant growth have been some of the factors related to low yields. Therefore, the aim of this work was to evaluate the growth of escarole crop in four seasons of year in Santa Maria, RS. The experiment was conducted in a randomized complete block design, 1 x 4, being a escarole (cultivar Escorola Lisa®) evaluated in four seasons of year (summer, autumn, winter and spring), in six replications. The evaluations were performed in a destructive manner every seven days, from date of transplant to harvest point. The following components were analyzed: number of leaves, number of residues, dry mass of leaves, dry mass of leaves, stem and residue. Thus, it was determined the parameters for growth analysis. With the data obtained, we performed a variance analysis, and presented significant results, and the means of each season of the year submitted to the Tukey test at 5% of error probability. The air temperature and global radiation influence crop cycle. Lower temperatures and lower incidence of radiation result in cycle extended, as observed in autumn. The escarole growth is influenced by seasons of year in Rio Grande do Sul (RS), and summer and spring finish the cycle in advance to others, presenting a larger leaf area. Summer and spring are most indicated season to escarole crop in RS, Brazil.

ABSTRACT: The objective of this study was to evaluate the silvicultural performance of four forest species introduced in a setting for integrated livestock forest (ILF) in a pasture in Lavras, Minas Gerais, Brazil. The species included were the Australian red cedar (seminal and clonal), African mahogany, teak, and guanandi. A split plot scheme with a randomized complete block design comprising four replicates and 48 plants per plot, was used in the following arrangement: (3(3x2) +7x2) m. The evaluation times (12, 18, 31, 36, and 43 months after planting) corresponded to the subplots. Performances of all four species were evaluated on the basis of their survival rate, height (H) and diameter at breast height (DBH). Based on the performance of the species with regard to these parameters, the clonal Australian red cedar showed a greater growth in DBH and height in the ILF setting as compared to the other species, which indicates it to be a suitable species for the region of Lavras, MG as long as its survival control occurs in the implantation phase.

Onion (Allium cepa L.) is one of the most important vegetables in family Alliaceae, which is cultivated worldwide. In onion, weeds are among one of the major concerns which cause its yield reduction. The present study was designed to assess the effectiveness of different methods for weed control in onion. In this study, five treatments were selected including control, black polythene mulch sheet, white polythene mulch sheet, Dual Gold spray @ 9.0 mL L-1 and Preact spray @ 7.5 mL L-1 to control weeds. The weedicides were applied as pre-emergence sprays before transplanting the seedlings. The experiment was laid out in Randomized Complete Block Design with three replications. From the results, it was concluded that there were significant differences among the studied weed control treatments. Among the five treatments, greater plant height (33.0 cm), number of leaves per plant (8), bulb diameter (4.7 cm) and bulb weight (73 g) were observed in the ridges covered with black mulch sheet. However, the minimum weed biomass (fresh and dry) was recorded in black mulch sheet and Preact pre-emergence weedicide spray (140 and 80 g in both). Thus, black polythene sheet as mulching material was found better option for weed management in onion fields.
