The characteristics and yield of basic seeds of two native Peruvian potato varieties "Peruanita" and "Amarilla Tumbay" (Solanum goniocalyx), obtained in temporary immersion bioreactors under greenhouse conditions, were evaluated in order to obtain quality seeds in a continuous and sustainable way to guarantee farmers' production and to meet national demand. For this purpose, microtubers and cuttings obtained by temporary immersion bioreactors (TIB) were cultivated in an area of 240 m2 at 3.201 masl, a completely randomized block design was applied with a bifactorial arrangement (varieties x propagules) of 4 treatments and 3 repetitions. The variables evaluated were: survival (SP) and plant height (AP) at 30 days, number of tubers per plant (NT), tuber diameter (DT), tuber weight (PT), tuber size (TT), tuber skin color (CP) and yield in kg per 14.05 m2 (R). Tubers produced from the microtubers stood out from the cuttings in yield for basic seed, presenting an R=26.89 ± 0,483 kg.14.05 m-2, PT= 0,12 ±0,0036 kg and a TD= 22.59 ±0,451 mm; being the variety "Peruanita" the most optimal in number and weight of tubers per plant for basic seed. The basic seed coming from microtubers was obtained in 5 months, being an alternative to guarantee a constant production, allowing to take care of the demand of farmers and to lower the costs of production.

Shallot production in Central Sulawesi recorded a decline from 8.651-8.362 tons, between 2017-2018. However, the use of an accurate composition of the planting medium serves as a possible alternative to boost the yield. Also, the introduction of organic matter tends to increase the nutrient content, influence the aeration, and subsequently leads to drainage. This study is aimed at determining the effect of plant media composition on shallot growth and yield. A randomized block design comprising 4 treatments, termed soil composition, husk charcoal, and goat manure. Each treatment was repeated at 5 times to achieve 20 experimental units. The results showed that the plant media composition indicated a significant effect on the parameters of plant height at age 4 and 6 Weeks After Plantings (WAP), quantities of leaves aged 4 WAP, tillers aged 6 WAP as well as tubers per clump. Similar impacts were also reported on plant height at 2 WAP, the number of leaves aged 2 and 6 WAP, fresh tuber weight, tuber diameter, accumulated weight loss, root length, and available moisture content. Furthermore, the addition of husk charcoal and manure at a volume ratio of soil: husk charcoal: manures = 2:1:1, tends to increase the quantities of leaves, tillers, tubers per clump, as well as plant height, fresh tuber weight, and shallot bulb diameter.

ABSTRACT            This study aims to determine the effect of bio slurry and cutting of seed tubers on the growth and yield of shallot plants in the Dukuh Kepoh Food and Horticultural Garden, Tohudan Village, Colomadu District, Karanganyar Regency with a height of ± 105 m above sea level, from April until June 2020.          This study used a factorial method with a complete randomized block design (RAKL), consisting of two treatment factors, while the two treatment factors with 12 treatment combinations, each treatment was repeated (3) times. The first treatment, the concentration of bio slurry (S) which consists of 4 levels, namely (S1: Bio slurry 0 ml / l, S2: Bio slurry 50 ml / l, S3: Bio slurry 100 ml / l, S4: Bio slurry 150 ml / l). The second treatment was cutting the seed tubers (P), which consisted of three levels (P1: Cutting 1/4 part of seed tubers, P2: Cutting 1/3 parts of seed tubers, P3: Cutting 1/2 parts of seed tubers).         The results showed that the treatment with bio slurry (S) had no significant effect on all observed parameters. Treatment by cutting seed tubers (P) had a very significant effect on plant height, weight of fresh tubers per plant, weight of fresh tubers per plot and had a significant effect on the number of fresh tubers per plant, but had no significant effect on the number of tubers per plot and weight of fresh stems. The combination between the treatment of bio slurry and cutting of seed tubers (SxP) did not significantly affect all observed parameters, The highest yield of fresh tubers per plot was obtained in treatment (S2P2) with a yield of 800.00 g, while the lowest tuber weight per plot was obtained in treatment ( S1P3) with a yield of 433.33 g.   Keywords: shallot, bio-slurry, seed tuber cutting

Exposure of bulbs to cold, a physiological phenomenon called vernalization, and bulb size are important factors in the production of lily bulbs and flowers. This study aimed to verify the influence of vernalization of bulbs on flowering cut lily plants, as well as the impact of size and shape of harvest on the production and quality of flowers and bulbs. In turn, the way the stems of the plants used for cut-flower production are cropped is of higher importance for the production of new flower bulbs. In this sense, the experiment was conducted in Viçosa, MG, in a greenhouse in a randomized block design, in split splot scheme with three replications, in which the vernalization periods (25, 35 and 45 days at 4 ± 1 C) constituted the plots; bulb sizes (diameters of 3.2-3.8 cm; 2.5-3.2 cm 1.9- and 2.5 cm), subplots and ways to harvest (full harvest of the stem at the required length for the commercial harvest of the flower, commercial stem harvest at the commercial length, maintaining 10cm of stem in the soil; removal of the floral buds as soon as their appearance is observed and harvest at the end of the season), the sub subplots. The bulbs were planted in beds, with 15 x 20 cm spacing. It was evaluated the number of plants that flowered and the number of flowers, the length and the diameter of the floral buds, fresh and dry weights, diameter and plant height as well as number, perimeter and amount of fresh and dry bulbs. There was a decrease in the plant height with the increase of the vernalization period and a reduction of the diameter of the planted bulbs, as well as of the number and the fresh and dry weights of the produced buds. The production of flowers and buds in number, size and weight was directly proportional to the size of the planted bulbs, while the form of harvest with removal of flower buds increased the number, the perimeter and the fresh and dry weights of the buds. Bulbs with diameter between 3.2 - 3.8 cm, stored for 25 days in cold chamber enable greater production of flowers and the highest stem height, factors that favor the increase in market value.

ABSTRACT The objective was to evaluate the effect of different spacings and mineral fertilizations on cactus pear growth and production in a randomized block design, with three replicates, in a 3 x 4 factorial scheme: three spacings, 1.00 x 0.50 m, 2.00 x 0.25 m and 3.00 x 1.00 x 0.25 m, and four fertilizations, 000-000-000, 000-150-000, 200-150-000 and 200-150-100 kg ha-1 of N, P2O5 and K2O, respectively. Plant growth was evaluated between 90 and 390 days and production and growth were evaluated at 620 days after planting. There were significant interactions between spacing and fertilization for plant height, number of cladodes and cladode area index from 90 to 390 days and for production of fresh and dry matter at 620 days after planting. Spacing influenced cladode area index, while fertilization influenced plant height, number of cladodes and cladode area index at 620 days after planting. Plant height showed cubic effect for the days after planting. Number of cladodes and cladode area index were dependent on spacing, fertilization and plant age, and fitted to cubic models. The best results of growth and production of fresh and dry matter are associated with NPK and NP fertilizations and the spacing of 1.00 x 0.50 m.

Abstract Plant growth is influenced by seed quality. Seeds need to be treated to prevent pest and disease disorders or to increase seed germination. Soybean planting was carried out in this study by the treatment of varieties and seed pre-treatment application before planting. The study aimed to measure the growth and yield of soybeans by varieties and seed treatment before planting, carried out in the Village of Nggembe, District of Bolo, Bima Regency. The study used factorial randomized block design with two factors. The first factor was soybean varieties consisting of two levels, namely Devon and Dena varieties, and the second factor was the application of pre-planting seed treatments consisting of four levels namely Cruiser, Marshall, Agrisoy, and without seed treatment, each treatment was repeated three times. Observations were made on the performance of agronomic crops and soybean yields. The results showed that the treatment of soybean varieties and the application of seed treatment had a significant influence on plant height and soybean productivity, and both treatments had interactions on parameters of plant height, number of filled pods, weight of 100 seeds, and soybean productivity with the best results successively produced by a combination of Devon-Control, Devon-Marshall, Devon-Agrisoy, and Dena-Cruiser.

The current investigation was carried out to examine the selection criteria for yield improvement in selected genotypes of Indian mustard. Twenty-four genotypes of Indian mustard were evaluated for seed yield and yield attributing characters with randomized block design with three replications. The analysis of variance showed significant differences among all the 24 genotypes against all the characters. The phenotypic and genotypic coefficient of variation were higher for most of the traits like seed yield per plant, number of secondary branches per plant and number of siliquae per plant. High heritability coupled with high genetic advance in percent of mean was registered for number of siliquae per plant, number of primary and secondary branches per plant, plant height, 1000 seed weight, siliqua length per plant and seed yield per plant suggesting predominant role of additive gene action for expression of these traits. The correlation study revealed that seed yield per plant was positively and significantly correlated with number of primary and secondary branches per plant, number of siliquae per plant, siliqua length per plant and 1000 seed weight at both phenotypic and genotypic level. The traits namely, number of secondary branches per plant recorded as highest positive direct effect followed by number of seeds per siliqua, number of siliquae per plant and plant height. Therefore, they may be carried out further evaluation in multilocational trials, biotic and abiotic stress like environmental conditions to check their stability and adaptability.
