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.

<p>ABSTRACT</p><p><br />Shallot is one of important commodity besides chili and potatoes. Shallot is cultivated on dry land. The dry land used in Indonesia is still relatively small, while the potential of this area is considered large for the development of agriculture. Pressurized irrigation system has the advantage of efficient use of water making it suitable to be applied on dry land. The study consisted of two experiments, the effect of irrigation volume and frequency of irrigation influence on the growth of shallot. The research was conducted at the Experimental Station Teaching Farm and Postharvest Laboratory Department of Agronomy and Horticulture, Bogor Agricultural University from October 2014 to April 2015. The research consisted of two experiments by using a Randomized Block Design with four replications. The treatment in the first experiment was percentage of the volume of irrigation water consisting of five levels (S100% ETc, S75% ETc, S50% ETc, S25% ETc (with sprinkler) and 100% ETc conventional (without sprinkler). The treatment in the second experiment was frequency of irrigation consisting of four levels (two times a day, once a day, once in two days one and once in three days). Results of the first experiment showed the plants could grow<br />and produced up to S25% ETc or 81.17% water available for evapotranspiration, but the best treatment was S100% ETc volume irrigation, based on yields. Watering with sprinkler irrigation provided better effect than manual watering which was usually done by farmers. The second eperiment showed that the best watering frequency for vegetative growth was once a day while for total yield was twice a day.</p><p>Key words: dryland, irrigation, shallot, sprinkler, total yield, vegetative growth,</p><p>ABSTRAK</p><p><br />Bawang merah salah satu komoditas unggulan nasional selain cabai dan kentang.

The present work aimed to evaluate the influence of use, as well as to determine adequate doses in organic fertilization of the bokashi type in the cultivation of two basil (Ocimum basilicum L.) cultivars. Seeds from the collection of the Floriculture Laboratory of the Phytotechnics Department of the Federal University of Ceará were used. The treatments used were arranged in a randomized block design (RBD), arranged in a 2x5 factorial scheme, consisting of two cultivars of basil (Genovese and Anão) and five doses of Bokashi, namely: 0, 3, 6, 9 and 18 g.L-1. Plants that received no dose (0 g.L-1) served as a control treatment. Each treatment contained 5 repetitions, with the plot consisting of 7 pots, one plant per pot, the useful unit a pot with a basil seedling. From the transplant, applications of bokashi were started in doses of 0, 3, 6, 9, and 18 g.L-1 in both cultivars. Both applications were performed every 20 days after the first application of Bokashi. Fivety five days after transplantation in the final pot, the following variables were analyzed: plant height, stem diameter, fresh and dry mass of the aerial part and the root. The 9 g.L-1 dose of Bokashi showed the best results for the variables analyzed for both cultivars, in addition to being efficient when compared to the control, in which the vegetative growth was incipient.
