BALANÇO DA FERTIRRIGAÇÃO EM MELOEIRO “PELE-DE-SAPO”  Manoel Januário da Silva Júnior1; José Francismar de Medeiros2; Fábio Henrique Tavares de Oliveira3; Indalécio Dutra21Departamento de Engenharia Rural, Escola Superior de Agricultura Luiz de Queiroz, Universidade de São Paulo, Piracicaba, SP, [email protected] de Ciências Ambientais, Universidade Federal Rural do Semi-Árido, Mossoró 3Departamento de Solos e Engenharia Rural, CCA, Universidade Federal da Paraiba, Areia, PB,  1 RESUMO O melão produzido no estado do Rio Grande do Norte é cultivado sob irrigação, sendo uma das culturas em que mais se pratica a fertirrigação. A fertirrigação tem se mostrado como a técnica mais adequada para parcelar a dose dos nutrientes em várias aplicações durante o ciclo da cultura. Entretanto, ainda não se conhece a eficiência dessa técnica. O objetivo deste trabalho foi avaliar o balanço dos nutrientes no sistema solo-planta, aplicados através da fertirrigação identificando os períodos críticos para o manejo da fertirrigação. Os tratamentos foram: doses de nitrogênio (83, 119 e 156 kgN ha-1) e doses de potássio (190, 271 e 352 kg K2O ha-1) aplicadas via fertirrigação e o experimento foi montado em blocos aleatorizados com três repetições. Coletou-se solo e planta aos 22, 33, 43, 54 e 69 dias após a semeadura e determinaram-se os teores de N, P e K na planta e no solo. O aumento da dose de nitrogênio provocou aumento das perdas desse nutriente e, quando se aumentou a dose de potássio houve acúmulo no solo. As maiores perdas de nitrogênio, fósforo e potássio ocorreram no período de maior exigência nutricional da cultura. UNITERMOS: Cucumis melo L., manejo da fertirrigação, índices de eficiência  SILVA JÚNIOR, M.

BALANCE OF FERTIGATION IN “PELE-DE-SAPO” MELON PLANTS  2 ABSTRACT Melon production in Rio Grandedo Norte state (Brazil) is grown under irrigation and it is one of the crops where fertigation is more used. The importance of fertigation technique is attributed to nutrient dose fractioning into several applications during crop cycle. Therefore, the efficiency of this technique is not known yet. This study aimed to evaluate nutrient balance applied through fertigation in a soil-plant system to identify critical periods for fertigation management. The treatments consisted of nitrogen doses (83, 119, and 156 kgN ha-1) and potassium doses (190, 271, and 352 kg K2O ha-1) applied via fertigation and the experimental design was randomized blocks with three replications. Soil and plants were sampled at 22, 33, 43, 54 and 69 days after seeding to determine plant and soil contents of N, P and K. The increase in nitrogen dose raised soil nitrogen losses, but the increase in potassium dose caused accumulation in the soil. Higher losses of nitrogen, phosphorus and potassium occurred in the crop higher nutritional demand stage. KEYWORDS: Cucumis melo L., fertigation management, efficiency indices

Postharvest Quality

Long-term use of inorganic fertilizers on leafy vegetables can increase soil acidity, harmful to the environment and leaving bad effects on human health. Organic fertilizer application is one of the safer alternatives with many beneficial effects by supplying nutrients for plant growth, environmental-friendly and producing an optimum quality of vegetables. Different organic amendment such as vermicompost, biochar and microbial compost has different effect on plant growth performance since good bacteria could improve structure of the soil and nutrient absorption. Therefore, this study aims to evaluate the effects of organic fertilizer on the growth performance and postharvest quality. The experimental design during planting was conducted in randomized completely block design with a factorial arrangement of treatmentswhile for postharvest quality study was conducted in completely randomized design. Organic fertilizer of vermicompost (110 g/plant), biochar (100 g/plant), microbial compost (80 g/plant) and chicken manure (37.5 g/plant) were treated on Pak choy two times on day 10 and day 24 after transplant. This research revealed the plant growth including plant height, leaf number and leaf length of Pak choy in all treatments were increased as growing stage increased. However, at the end of growing stage, microbial compost and vermicompost resulted in the highest of growth characteristics. In terms of postharvest quality, microbial compost showed the highest fresh weight and premium quality. This study proved that microbial compost at 80 g/plant exhibited optimum growth performance and the best postharvest quality of Pak choy.

This research aims to find out the effect and functional relationship of coconut ash organic fertilizer application on the increasing yield and quality of waxy corn. There are seven treatments of coconut ash fertilizer dosage, i.e. 0.00 ton/ha, 0.75 ton/ha, 1.50 ton/ha, 2.25 ton/ha, 3.00 ton/ha, 3.75 ton/ha, and 4.50 ton/ha. Data is analyzed using one way anova, t test for 2 independent samples, and simple linear regression analysis. Fertilizer dosage has significant effect on ear height position from soil surface, the number of seed row on ear, ear weight with and without dried husk, waxy corn production with and without dried husk, and starch, amilose, and amilopectin contents. The highest average of ear height position and the amount of seed row is obtained at dosage 0.75 ton/ha. Dosage 2.25 ton/ha gives highest average for ear weight with and without dried husk, while dosage 3.75 ton/ha results highest average for variables of waxy corn production with and without dried husk. Dosage 3.75 ton/ha also gives highest average for starch and amilopectin contents and lowest average for amilose content. One way relationship happens between fertilizer dosage with ear height position, the amount of seed row, ear weight, waxy corn production, starch and amilopectin contents.

[PRODUCTIVITY AND FRUIT QUALITY OF CANTALOUPE AT DIFFERENT RATES OF FRUIT THINNING AND NPK FERTILIZER APPLICATION]. Productivity and fruit quality of cantaloupe depend on the availability of nutrients and the number of fruits maintained. The aim of this study was to compare the productivity and fruit quality of cantaloupe at different rates of fruit thinning and NPK fertilizer application. The research was conducted in August-October 2020 on street Kapuas V, Lingkar Barat Village, Gading Cempaka District, Bengkulu city. A field experiment was arranged in a randomized complete block design (RCBD) with 3 replications for alloting two factorial treatments structure, namely rates of fruit thinning (no fruit thinning, thinned to one fruit /plant, thinned to two fruits/plant, and thinned to three fruits/plant) and rates of NPK fertilizer application (400, 600, and 800 kg/ha) on rhe experimental plots. The results showed that fruit thinnings resulted no increament in crop productivity, but the fruit quality was improved as fewer number of fruits were retained on each plant. The NPK fertilizer at 400, 600, and 800 kg/ha were not able to increase the productivity of cantaloupe  and the quality of the  produced fruit when  the application were made only at planting and 23 days after planting.
