This study aims to determine the response given by the red lettuce plant to the provision of nutrients in the form of nutrient solution (AB Mix) on the horizontal installation of the hydroponic system. The study was conducted on December 20, 2017 until February 16, 2018 at the PKK Gardens Education Center in Bengkulu province. Seeding process of Red Lettuce Seedlings is carried out for 14 days then transferred to a net pot at the installation in the Greenhouse. Fertilizers with the Fiora A and B Brands are dissolved to be mixed in a nutrient bath with a capacity of 3000 L with a nutrient density of 500 ppm in the Greenhouse to be distributed to the horizontal installation of the hydroponic system inside the Greenhouse. Then growth observations were carried out on 10 plant samples with parameters of leaf length, leaf width, number of leaves, stem height, andstem diameter for 30 days. The results obtained by sample 1-10 have an  average growth and development that is not much different. The maximum leaf length and leaf width parameters are in samples 2 and 3. While the highest number of leaf strands in sample 3 is 22 strands with an average of 18 strands and sample 4 has the highest stem height parameter of 3.5 cm with an average height 2.7 cm. The largest stem diameter in sample 4 is 4.1 cm with an average of 3.38 cm. The response of red lettuce after the last week showed symptoms of leaves that are less red with relatively more withered body.

Mangrove forests have important role in coastal ecosystems, for example to overcome marine abrasion, bird nesting sites, forming ecological balance, capturing and localizing sediments, preventing soil acidity and inhibiting sea water intrusion. The success of mangrove reforestation is largely determined by the success in preparing mangrove seedlings. Nursery beds made of bamboo to accommodate 4 species of mangrove seedlings, that are Bruguiera gymnorrhiza, Rhizopora apiculata, Rhizopora mucronata and Rhizopora stylosa with 6 replications and each of 3 individuals of each type. The variables measured were plant height, number of leaves and stem diameter. Statistical analysis with the Costat & Co. program The results showed that the average growth of stem height from the 4 mangrove seedlings measured from 6 -13 MST was 1.5 cm, 1.4 cm, 0.8 cm and 0.7 cm respectively. The average number of leaves from the 4 mangrove seedlings were 0.6, 1.2, 0.6, and 0.6 strands respectively and the average stem diameter of the 4 mangrove seedlings was 0.1 cm. The mangrove seedlings of Rhizopora mucronata and Bruguiera gymnorrhiza species that produced higher growth rates of stem height than others, and Bruguiera gymnorrhiza which produced the highest average number of leaves compared to the other three types.

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)

Khaya senegalensis (Desr) A. Juss is a perennial deciduous tree which has many uses in developing nations. The population of the tree is rapidly declining due to no conservation efforts to prevent the species from endanger and extinction. At the moment there is dearth information on manure types required to raise healthy seedlings of the tree species in the study area. To conserve this genetic resource, germination and early growth rate experiment was carried out using seeds collected from three locations (eco-zones) (Alkaleri, Bauchi and Toro). Matured seeds of K. senegalensis were collected from mother tree stand in the three locations. One hundred and fifty seeds (150) from each location were sown in perforated polythene pots at an average depth of 2-3 cm. After germination i.e. 30 days after planting, different manures were applied to the seedlings. The experiment was laid out in a Completely Randomized Design (CRD) with three treatments, namely: poultry dung, cow dung and NPK manures; the experiment was replicated four times. Data on seeds germination variables of interest (seedling heights, number of leaves, collar diameter, leaf area, leaf width, leaf length and fresh weights) were measured. Seedlings height were measured using meter rule, collar diameters using a venier caliper, numbers of leaves were determined by manual counting the number of leaves on the seedlings, leaf area was measured by tracing leaves of seedling on a graduated graph sheet. Data collected on seed germination and early growth rate were subjected to descriptive statistics and inferential statistics (ANOVA). Where significant differences occurred, Tukey test was used to separate the means. Based on this finding, germination of seeds commenced after 10 to 14 days. Locations and manure types had significant effects on the mean heights, number of leaves, collar diameter, leaf area, leaf width, length and fresh weights of K. senegalensis seedlings in the study area. Thus, for species conservation and genetic heredity, seeds sourced from Bauchi eco-zone was the best with poultry manure as the best performed manure for the raising of K. senegalensis seedlings in the study area.

This study aims to determine the growth response of the love wave plant (Anthurium plowmanii) on Petrovita leaf fertilizer in an advanced nursery conducted in August - October 2011 in Panarung Village, Pahandut District, Palangka Raya City. Single treatment design (one factor) with 10 (ten) repetitions in the form of Petrovita leaf fertilizer (D) consisting of 5 concentration levels, namely: d1 = 0.5 ml l-1 (0.05%); d2 = 1.0 ml l-1 (0.10%); d3 = 1.5 ml l-1 (0.15%); d4 = 2.0 ml l-1 (0.20%); and d5 = 2.5 ml l-1 (0.25%) using a completely randomized design. Observations were made when the plants in the advanced nurseries had received treatment applications 4 times at intervals of 2 weeks. Observations were made on plant height (cm); stem height (cm); number of leaves (leaves); leaf length (cm); leaf width (cm); and leaf area (cm2). The results of this study indicate that Petrovita complete leaf fertilizer has a very significant effect on increasing the growth of love wave plants aged 8 MST in advanced nurseries. Petrovita fertilizer concentration of 0.2% or 2 ml l-1 (d4) is the best and most efficient treatment for love wave plants in advanced nurseries. It is recommended to increase the growth of love wave plants in advanced nurseries using Petrovita 0.2% concentration but tried with an interval of less than 2 weeks (for example once a week).

Ten genotypes of maize collected from National Center for Genetic Resources and Biotechnology (NACGRAB) were induced with X-ray for morphological and molecular assessment. The experimental design was complete randomized design with four replicates. Morphological and molecular statistical analyses of treated genotypes were conducted using SAS and Power Maker Packages, respectively while dendrogram was generated using Jaccards similarity coefficient using Unweighted Paired Group Method and Arithmetic Averages (UPGMA). The study revealed significant difference which is an indication of genetic variation of characters in treated maize. Genotype DTSR-Wco performed best in plant height (62.35 cm), leaf length (62.35 cm), number of leaves (3.15), leaf width (7.55 cm) and dry leaf biomass (0.24 g). X-ray at 90 Kv/mass, 95 Kv/mass and 100 Kv/mass decreased plant heights to 54.25cm, 53.87cm and 54.10cm respectively compared to Control. Heritability estimate was greater than 70% for all characters evaluated. Genotype TZM 1551 at 0 Kv/mass yielded the highest concentration of DNA at 2841.60 ng/ul and the highest genomic DNA concentration was obtained at 95 Kv/mass for TZM 132 with 1.91%. Primer BMC 1755 was most polymorphic with 58.77% in treated maize genotypes. The plant height was strongly correlated with leaf length (r=0.9), leaf width (r=0.76) and number of leaves (r=0.77). Principal component analysis showed close relationship between plant height (-0.03) and leaf length (0.05) compared with leaf width (-0.67) and number of leaves (0.69). Dry shoot biomass (0.05) was closely related to dry root biomass (-0.03) and dry leaf biomass (-0.04).

Fritillaria meleagris is an endangered Eurasian species with declining populations in most of its distribution area. The signifi cance of the present study is to provide details for improving methods, how age-state structure can be identifi ed in a population. This could help finding the appropriate way of site-management where this species occurs. We investigated two F. meleagris populations in the western part of Hungary (Gyékényes, Tüskeszentpéter). We grouped the recorded plants into five age-state categories: dormant, juvenile, subadult, vegetative- and reproductive adult. We investigated diff erent plant traits such as plant height, number of leaves, leaf width and leaf length. The relative frequencies of leaf numbers differed signifi cantly between the two sites each year. Generally, the majority of the flowering plants had 5-6 leaves at both sites. Only plant height was positively related to plant reproductive success, but there were no clear trends in leaf width and leaf length. There are considerable diff erences in age-state ratios between our sampling sites. The proportion of reproductive plants was noticeably higher in both years in Tüskeszentpéter. Transition into dormant state was regular from all age groups at both sites.
