Planting potatoes in the tropical lowlands as an effort to reduce the adverse effects of planting in the highlands such as erosion, pests and plant diseases has been carried out and the tubers have been successfully obtained. Planting of potato seeds was carried out with an aeroponic system and climate modification in the root zone cooling environment. Climate modification is carried out at an altitude of 250 m asl and <125 m asl. The stability of the temperature in the aeroponic chamber can be maintained by regulating the time of spraying cold nutrients through the nozzles to the root area. However, the importance of the time to provide nutrition in order to maintain the optimal temperature of the root area in aeroponic systems in the lowlands has not been widely reported scientifically. The purpose of this study was to obtain the appropriate time for nutrition in order to maintain optimal chamber temperature and to have an effect on the growth and yield of potato seeds. The research was conducted in the greenhouse of the Faculty of Agriculture, Jenderal Soedirman University, Purwokerto, Central Java, Indonesia. Height of place <125 m above sea level. The study was conducted from July to September 2017. The factors that were tried in the study were as follows: 1. Length of time for nutrition (T): T1: 2.5 minutes OFF and 15 minutes ON; T2: 5 minutes OFF, 15 minutes ON, T3: 10 minutes OFF, 15 minutes ON, T4: 15 minutes OFF, 15 minutes ON, 2. Varieties (V): V1 (Atlantic), V2 (Granola). Growth parameters observed: plant height, number of leaves, number of tubers, tuber weight. Experiment using a randomized block design with 3 replications. The data were analyzed by F test and continued with Duncan’s Multiple Range Testof 5% level.The results showed that the duration of nutrient administration by setting a timer gave different results on the growth and development of aeroponic plants of potato seeds in the lowlands 125 m above sea level. The duration of nutrition administration 2.5 minutes OFF gave the highest number of tubers and tuber weight compared to the duration of nutrition 5 minutes, 10 minutes and 15 minutes OFF. The number of tubers obtained is 7.3 tubers / plant with boto an average of 2 mg. The duration of nutrition is 5 minutes, 10 minutes and 15 minutes OFF does not produce tubers.

ABSTRACT The growth and yield of taro plants can be influenced by the planting material used, and the use of improper types of planting material can cause plants to be unproductive according to potential yields. The use of planting materials derived from tubers is expected to increase the yield of taro. This study aims to determine the best type of planting material to increase the yield of taro. The experiments were carried out in the villages of Antirogo, Sumbersari, Jember, East Java with an altitude of ± 89 meters above sea level starting in April 2018 to October 2018. The experiment used a Randomized Block Design (RBD) method with 2 treatment factors. Factor 1 is the type of planting material (B), B1: Bulbs; B2: Puppies; B3: Stolon. Factor 2 is taro variety (V), V1: Green Taro; B2: Brown Taro; B3: Purple Line Green Taro. Each repeated 4 times. The results showed that there was an interaction between the use of different types of planting material and varieties that had an effect on tuber weight per plant. The type of planting material has a significant effect on the number of tillers, leaf area, tuber weight, and tube diameter. Varieties significantly affect all observed variables. The treatment that gave the best results was planting material from tubers (B1) and Purple Line Green taro varieties (V3) with tuber yield per plant 362.58 grams (± 14.5 tons/ha). Keywords: taro, planting material, varieties ABSTRAK Pertumbuhan dan hasil tanaman talas dapat dipengaruhi oleh bahan tanam yang digunakan, dan penggunaan macam bahan tanam yang kurang tepat dapat menyebabkan tanaman tidak produktif sesuai dengan hasil potensial.

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

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.

An experiment consisting of four phosphorus levels (0, 40, 60 and 80 kg/ha P2O5) and five zinc levels (0, 10, 20, 30 and 40 kg/ha ZnSO4) was laid out in randomized block design in factorial mode to find out the effect on yield and quality of fodder cowpea [Vigna Unguiculata (L.)Walp.]. Growth parameters viz. plant height, number of leaves, number of branches, leaf length, leaf width and leaf stem ratio were improved with the application of 60 kg/ha P2O5 and 20 kg/ha ZnSO4. Application of 60 kg/ha phosphorus recorded 27.64 t/ha yield, which was 7.50 and 55.6 % higher than 40 kg/ha and no phosphorus application, respectively. Application of zinc in the form of ZnSO4 @ 20 kg/ha increased significantly the green fodder yield (25.89 t/ha). Interaction effect of phosphorus and zinc application was found significant with respect to green fodder, dry matter yield and nutrient uptake. Yield, phosphorus and zinc uptake in cowpea fodder were showing declining trend at combination of application rate more than 60 kg/ha P2O5 and 20 kg/ha ZnSO4.

O experimento foi desenvolvido no campo experimental da Embrapa Mandioca e Fruticultura Tropical, em Cruz das Almas, Bahia, no delineamento em blocos casualizados, com cinco tratamentos e cinco repetições. Foram obtidos dados biométricos (altura de planta, diâmetro de caule e área foliar) e de produção. Não houve diferença significativa entre as médias de crescimento e produtividade do mamoeiro nos diversos tratamentos, indicando não haver diferença entre as fontes nítrica e amoniacal para fertirrigação. A substituição do sulfato de amônio por nitrato de cálcio como única fonte nitrogenada para o mamoeiro promoveu um ganho de produtividade de 14,79%, elevando, porém, o custo de produção em 649,84%. A aplicação de nitrogênio ao solo no período de 12 meses, considerando 50% do período com sulfato de amônio e 50% com de nitrato de cálcio, não causou acidificação ou aumento do pH do solo. UNITERMOS: Fertirrigação, parâmetros biométricos, produtividade.  SOUZA, T.

GROWTH AND YIELD OF PAPAYA UNDER COMBINATIONS OF NITROGEN SOURCES APPLIED BY IRRIGATION WATER  2 ABSTRACT The purpose of this work was to study the effects of different combinations of nitrogen sources (ammonium sulfate and calcium nitrate), applied by irrigation water, on biometric and production parameters of papaya cv. Tainung # 1. The experiment was carried out at Embrapa Cassava and Tropical Fruits, in Cruz dasAlmas,Bahia, under a randomized block design, with five treatments and five replications. Biometric data (plant height, stem diameter and leaf area) and production ones were collected. There was no significant difference among treatments, i.e., no difference between the nitrical and ammoniacal nitrogen sources at growth and production stages of the crop. The replacement of ammonium sulfate by calcium nitrate as the only nitrogen source for papaya provided a gain of 14.79% in yield, but the productions of cost increased 649.84%. The application of nitrogen to the soil during 12 months by ammonium sulfate during 50% of the period and calcium nitrate in the remaining did not cause acidification or increase of soil pH.KEYWORDS: Fertirrigation, growth parameters, productivity

Abstract   This study aims to determine the effect of compost and biochar fertilizer at a dose of 15 tons ha-1 made from livestock manure and its interaction on the growth and yield of red chili plants. This research was conducted in Blahkiuh Village, Abiansemal District, Badung Regency, Bali with an altitude of 400-500 m above sea level. This research was started from February 2020 to July 2020. The design used in this study was a factorial randomized block design (RBD) consisting of 2 factors, namely: chicken compost with 4 levels and biochar 2 levels by testing the types of compost and biochar. The interaction between the treatment effect with the type of compost and the type of chicken biochar had no significant effect on all observed variables. The treatment of compost application had a significant to very significant effect on most of the observed variables, except for the number of leaves, which had no significant effect. The treatment of chicken biochar dosing had a significant to very significant effect on most variables except for the maximum number of leaves and fresh weight per fruit, which had no significant effect. The results showed that the highest fresh fruit weight was obtained in the type of compost given by chicken livestock, namely 1499.56 g or an increase of 46.46% compared to the lowest treatment obtained without compost, namely 1023.85 g. To increase the growth and yield of red chili plants, it is recommended to use compost types of chicken livestock and chicken biochar at a dose of 15 tonnes ha-1 and further research is needed on the provision of biochar and compost types at different locations and types of plants.   Keywords:  compost, biochar, and chili plants.
