Os tratamentos foram dispostos em delineamento em blocos casualizados usando arranjo fatorial 3 × 2, referente as doses de calcário de 1,4; 2,5 e 3,6 t ha-1, 80 e 160 kg ha-1 de K2O na forma de cloreto de potássio. Pelos resultados, a irrigação com água salina (3,6 dS m-1), em comparação com dados da literatura de plantas irrigadas com água de boa qualidade, não comprometeu a capacidade produtiva do maracujazeiro amarelo. Dentre os tratamentos, a combinação de 80 kg ha-1 de K2O com 3,6 t ha-1 de calcário calcítico proporcionou os maiores valores de massa média dos frutos, produção por planta e produtividade da cultura. Apesar da alta salinidade da água de irrigação elevar o caráter salino do solo no ambiente radicular das plantas durante o período da estiagem, as águas do período chuvoso e as condições físicas do solo proporcionam a lixiviação dos sais e possibilitam o uso de água com restrições salinas na agricultura.   Palavras-chave: Passiflora edulis, calagem, lixiviação de sais     CAVALCANTE, L.

YELLOW PASSION FRUIT PLANTS PRODUCTION ON SOIL WITH LIME AND POTASSIUM UNDER IRRIGATION WITH SALINE WATER       2 ABSTRACT   The experiment was carried out in Coronel Ezequiel county, Rio Grande do Norte, Brazil, in order to evaluate the effects of limestone and chloride potassium in production components of yellow passion fruit plants and soil salinity, caused by irrigation with saline water of 3.6 dS m-1 during the dry season, and salt leaching of the soil promoted by waters of the rainy season. Treatments were arranged in randomized blocks using factorial design of 3 × 2, referring to three levels of limestone,  1.4, 2.5 and 3.6 t ha-1 and two potassium levels,  80 and 160 kg ha-1 in potassium chloride form. According to present results, irrigation with saline water (3.6 dS m-1), in comparison with data from the literature about plants irrigated with non-saline water, did no compromise the productive capacity of yellow passion fruit. Among the treatments, the combination of 80 kg ha-1 of K2O with 3.6 t ha-1 of limestone provided the fruits production with more mean mass, yield per plant and crop yield. Although the high salinity of the irrigation water increases the soil saline character on root environment of the plants during the dry season, the rainy season waters and the soil physical conditions provide the salt leaching and allow the use of water with saline restrictions in agriculture.   Keywords: Passiflora edulis, liming, salt lixiviation

The research had as objective to study the influence of the doses of nitrogen, phosphorus and potassium on soil fertility and nutritional status of yellow passion fruit plants. The experimental design was in randomized blocks in an incomplete fractioned factorial 1/2 (4 × 4 × 4), with four doses of N (150, 300, 600 and 1200 Kg-1 ha-1 yr-1 N); four doses of P2O5 (200, 400, 800 and 1600 kg-1 ha-1 yr-1) and four doses of K2O (100, 300, 500 and 700 kg-1 ha-1 yr-1). The fertilizers used were the ammonium nitrate = 32% N; triple superphosphate = 44% P2O5 and potassium chloride = 60% K2O. In the fertility of the nitrogen fertilization increased the content of phosphorus and sulfur. The doses of P2O5 increased the concentration of P in the soil. The doses of K2O influenced the increase in the content of K in the soil in the harvest 2013/2014. There was an interaction of the doses of N and K2O in the availability of K in the soil in the harvest 2012/13 with the maximum levels of K, in the doses of 200-400 kg N ha-1 and 600 to 700 kg ha-1 of K2O. In the nutritional state the yellow passion fruit plants was influenced by the doses of N for the sulfur content of the leaves. The maximum content of S leaf concentration of 3.63 g kg-1 was obtained in the dose estimated at 1120 kg ha-1 of P2O5.

AbstrakKelurahan Lau Cih dan Sidomulyo merupakan dua kelurahan di Kecamatan Medan Tuntungan yang terbanyak partisipasi rumah tangga dalam usaha pertanian. Sebanyak 20% kelompok wanita berperan di bidang pertanian. Pada kegiatan pengabdian kepada masyarakat sebelumnya, Kelompok PKK Kelurahan Lau Cih dan Sidomulyo telah dilatih untuk melakukan penanaman tanaman markisa dataran rendah dalam rangka pemanfaatan pekarangan. Tanaman markisa tumbuh subur dan menghasilkan buah dalam jumlah besar, tetapi buah markisa yang dipanen hanya dimakan dalam bentuk segar. Kurangnya informasi dan keterampilam kelompok PKK dalam pengolahan buah markisa hingga kini buah markisa masih dijual dalam bentuk segar. Tujuan kegiatan adalah: 1. Sosialisasi pengolahan buah markisa menjadi sirup markisa. 2. Melatih kelompok PKK dalam pengemasan produk sirup markisa.3. Melatih kelompok PKK untuk mampu mengolah limbah buah markisa (kulit buah dan biji markisa) menjadi bedak dingin kulit markisa. Kegiatan IPTEKS ini telah dilaksanakan pada 2 kelompok PKK kelurahan Lau Cih dan Sidomulyo yang masing-masing diikuti 20 orang wanita PKK. Metoda yang digunakan untuk memecahkan masalah diatas adalah dengan memberikan pengetahuan dan pelatihan maupun tekhnologi pengolahan sirup markisa dan limbahnya dilanjutkan dengan pembinaan yang dilakukan secara periodik melalui koordinasi dengan ketua kelompok wanita PKK.Hasil yang diperoleh adalah peningkatan pengetahuan dalam pengolahan sirup markisa, pengemasan produk sirup markisa, pengolahan limbah markisa menjadi bedak dingin kulit markisa dan scrub biji markisa.Kata kunci: Lau Cih, Sidomulyo, kelompok wanita PKK, markisa kuning, sirup markisa, pengemasan, pekaranganAbstractLau Cih and Sidomulyo are the two urban villages in Medan Tuntungan sub-district with the highest share of household participation in agriculture. As many as 20% of women's groups play a role in agriculture. In previous community service activities, the PKK Group of Lau Cih and Sidomulyo Villages have been trained to plant lowland passion fruit plants in order to utilize the yard. Passion plants thrive and produce large amounts of fruit, but harvested passion fruit is eaten only in fresh form. Lack of information and skills of PKK groups in the processing of passion fruit until now passion fruit is still sold in fresh form. The purpose of the activities are: 1. Socialization of passion fruit processing into passion fruit syrup. 2. Training PKK groups in packing of passion fruit syrup.3. Train PKK groups to be able to process passion fruit waste (fruit peel and passionfruit seed) into a cool powder of passion fruit ski. This IPTEKS activity has been carried out in two groups of PKK Lau Cih and Sidomulyo villages, each of which followed by 20 women. The method used to solve the above problem is to provide knowledge and training as well as technology of passionfruit syrup processing and waste followed by coaching conducted periodically through coordination with the leader. The obtained is the increase of knowledge in the processing of passion fruit syrup, packing passion fruit syrup, Passion fruit waste treatment into a cool powder of passion fruit skin.Keywords: Lau Cih, Sidomulyo, PKK women group, yellow passion fruit, passion fruit syrup, packing, yard

Abstract: Yellow passion fruit has conquered a significant position in the agribusiness of tropical fruits; therefore, farmers have been interested in expanding their groves, and technical information that guarantees the high yield of the farmings is needed. Aiming to observe factors related to the propagative material targeted at quality and maximization of the genetic potential, the objective of the study consisted in assessing germination and emergence of passion fruit seeds collected in three positions in the fruits and submitted to different methods of mucilage removal (aryl). The passion fruits were split in three parts: distal, medial and proximal and the contents of each part was divided in two. The content of each part of the fruit was submitted to mechanical and by fermentation methods for removal of aryl. It is concluded that the seed position in the fruit does not interferes with the germination. The aryl removal method by mechanical extraction affects the germination and seedling emergence.
