The problem of generative propagation of soursop is its seeds take a long time to germinate which are caused by the hard seed coat. The solution to solve that problem is scarification and coconut water soaking to simply the process of imbibition and seed germination and also stimulate the growth of shoot. This objective of the research was to determine the effect of the scarification position and the soaking with various concentrations of coconut water on seed germination and growth of soursop seedling. This research was held at the Faculty of Agriculture field, the University of Sumatera Utara in March - July 2017. The research used a factorial randomized block design with two factors and three replication. The first factor is the scarification position (without scarification, stomach scarification, top scarification) and the second factor is coconut water soaking (0%; 25%; 50%; 75 %). The result of the research showed that the germination rate parameter, germination percentage, crop height, number of leaves, root volume and dry weight of crop significantly higher on without scarification treatment than with scarification treatment. The interaction between the scarification position and soaking with various coconut water concentrations was not significantly affecting the seed germination and growth of soursop seedling.

Size Heterogeneity

The variation of the seed size in each species and individuals might be from of difference species adaptation for  a difference environment. This difference may also arise from the constraints of limited formation of seed size. The use of adaptive ciltivars on the growth environment is very influential on the succes in the farm field. This research was aimed to find the adaptation of phase and size seed of two cultivars of soybeans in Jatinangor and Cikajang. This research was held in Jatinangor (Sumedang regency) and Cikajang (Garut regency) from April to July 2016. The design that used in this research was Randomized Block Design (RBD) and Duncan at 5% rate. Improved cultivars that tested in this research were placed at Grobogan and Anjasmoro which were repeated 5 times. The results of experiment showed that adaptation of size seed showed of 100 grains and large seeds. The low temperature condition can increase of variability of seed size. Heterogeneity of environment can not sustain the size of soybean seed. Genetic and environment factors influence significantly for weight of 100 grains and seed size Grobogan in Jatinangor. The weight of 100 grains Grobogan in Jatinangor and Cikajang haved a greater than Anjasmoro. Environmental factors influence yield of soybean, weight of 100 grains of cultivars in Cikajang haved a greater than Jatinangor caused by the seed size.

Three experiments were carried out with the objective of achieving high effectiveness in calli induction from high heterozygosis leaf explants of Coffea arabica through indirect somatic embryogenesis. A randomized-block design in a 2x5 factorial arrangement made up of two media [BOXTEL & BERTHOULY (1996) and TEIXEIRA et al. (2004)] and five C. arabica genotypes were used in the first experiment. In the second experiment the embryogenic calli production potential was evaluated in ten genotypes. Each of them was considered as a treatment. In the third experiment the variations in both 2.4-D (2.5 e 20µM) and 2-iP (2.5 e 20µM) concentrations in TEIXEIRA et al. (2004) medium and secondary media were evaluated. Crops were kept in a growth room under darkness, at 25±2oC. The medium described by TEIXEIRA et al (2004) was found to be superior when compared to that described by BOXTEL & BERTHOULY (1996) in the 2.2 and 7.2 genotypes. An opposite behavior was noticed in 4.2 genotype, that is, BOXTEL & BERTHOULY (1996) had medium superiority. Both 3.0 and 5.0 genotypes had the same behavior in both media studied, which shows that the somatic embryo production depends on the genotype. Calli induction depends on the 2-iP and 2.4 D ratio. The 20.0µM of 2.4-D and 20.0µM of 2-iP combination caused the highest embryogenic calli induction rate.

The solubility and availability of Si from the feldspar, silica, and zeolite as Si-bearing minerals were studied in a sandy soil. Silicon uptake by the soybean (<em>Glycine max L.</em>)<em> </em>plant was discussed. The minerals used were applied before planting in two separate rates; rate 1 ≈ 595.2 and rate 2 ≈ 1190.5 kg ha<strong><sup>-1</sup></strong> accompanied by a ≈ 4.8 kg ha<strong><sup>-1</sup></strong> constant rate of the K-humate sprayed as a solution on soil after planting in a complete randomized block design. The dissolved Si from the different minerals at rate 2 followed an opposite direction to their SiO<sub>2</sub> percentage that may be due to the structural differences: silica (1.46 mg kg<strong><sup>-1</sup></strong> - SiO<sub>2 </sub>=98.4%) &lt; zeolite (1.71 mg kg<strong><sup>-1</sup></strong> - SiO<sub>2 </sub>=75.9%) &lt; feldspar (2.09 mg kg<strong><sup>-1</sup></strong> - SiO<sub>2 </sub>= 71.9%). The individual mineral treatments at rate 2 have almost decreased the available NPK estimated after soybean harvesting. The K-humate has enhanced the effect of silica at rate 2 for the available N and P. The soybean seed yield (kg ha<strong><sup>-1</sup></strong>) increased significantly by 117.9% for the S1 + H, 109.2% for K-humate and 57.5% for the Z2 + H. The seeds’ Si (mg kg<strong><sup>-1</sup></strong>) increased significantly from 3.6% to 102.9% affected by the silica treatments.

Abstract: The production of bell pepper seeds may be affected by the plant management and harvesting point of fruits. The goal of this study was to evaluate the quality of organically produced bell pepper seeds according to free plant growth, branch thinning and ripening stage. The experiment was conducted in a greenhouse with randomized block design; plants were tutored to parallel tape supports, with and without branch thinning, and fruits were harvested at three ripening stages (completely green, green/reddish and red). The following determinations were made: seed moisture content of at the time of harvest and after post-harvest rest, number of seeds per fruit, seed germination, and seedling emergence. It is possible to conclude that the production of bell pepper seeds in an organic system is viable, resulting in seeds with a germination percentage and seedling emergence above 90%. The management system of plants without branch thinning results in the production of seeds with greater viability and higher quantity per fruit. The cultivation of bell peppers for seed production may be carried out with fruits at the green ripening stage (51 days after anthesis), without any quality loss.

Papaya is a very popular fruit in the tropical and subtropical regions of the world and has witnessed an increase in demand. This has fuelled an interest to develop region specific hybrids with desirable vegetative growth and vigour.  Hence a field experiment was carried out at College of horticulture and forestry, Navsari Agricultural University in Gujarat during 2018-2020 in randomized block design with three replications to know the mean performance of parents and hybrids for comparative growth performances of papaya. Wherein, thirty papaya hybrids were developed from six morphologically distinct parents through full diallel crossing technique and all the parents and hybrids were evaluated for their germination and growth parameters. The variability was distinct in all hybrids and parents for germination percentage, days taken to germination, periodical plant height and girth, number of leaves, petiole length and internodal distance. Amongst all the parents, Pusa Delicious, CO-8 and Lucknow Local exhibited improved germination, better vegetative growth and dwarf stature, respectively. Among the hybrids, Pusa Delicious x Lucknow Local was found to have dwarf stature with minimum internodal length however, the reciprocal cross: Lucknow Local x Pusa Delicious recorded maximum plant girth and number of leaves. Based on their mean performance, these parents can be used for further breeding programmes and hybrids could be exploited for cultivation.

The efficiency of inorganic fertilizers can also be done by using mycorrhizal biofertilizers. Efforts to increase corn growth need to be done by using inorganic fertilizers and biological fertilizers. This study aims to determine the effect of urea and mycorrhizae doses on the growth of maize (Zea mays. L). The research was conducted in Gejugan Village, Andong District, Boyolali Regency, an altitude of 154 m above sea level with grumusol soil type. This study used a completely randomized block design (RAKL) with two treatment factors, namely the first factor urea fertilizer dosage consisting of 4 levels, namely N0 = 0 kg / ha, N1 = 100 kg / ha, N2 = 200 kg / ha, N3 = 300 kg. / ha, and mycorrhizae consists of 3 levels, namely M0 = 0 g / plant, M1 = 5 g / plant, M2 = 10 g / plant. with 3 repetitions. The results of this study indicated that the dose of urea fertilizer affected the growth of maize, while the mycorrhizal dose did not affect the growth of maize except for the length of the plant roots. The effect of urea dose interaction with mycorrhizae only affected the root length growth of maize. The best growth of maize plants after being given a dose of urea as much as 100 kg/da and mycorrhizal biofertilizer 10 g / plant with the longest roots (40.44 cm)
