Abstract

Diallel analysis of multiple traits is a comprehensive approach to evaluate general combining ability (gca), specific combining ability (sca) and reciprocal effects of parents and it crosses by involving many traits simul­taneously. Describing of cross-by-traits biplot (CT Biplot) can be used to describe the multiple traits diallel analysis. In order to improve the yield potential, four parents of the local varieties and two parents of the high yielding varieties of mungbean were evaluated their multiple traits combining ability by using Griffing Methods I. Results of the research show, there are 3 meaning sectors (MS) and 2 non-meaning sectors (NMS) of crosses and multiple traits. The parents Lasafu Lere Butsiw (LLBs) and Gelatik contained high gca in one MS which associated with traits of the grain weight, number of seeds per pod, number of seeds, number of filled seeds, number of pods, and number of filled pods (MS-1). The parents Lasafu Lere Butsiw fer Namamas (LLBfN), Lasafu Lere Butnem (LLBn), and variety No. 129 in the next MS (MS-3) related to the 100 seed weight trait, meanwhile the parent Mamasa Lere Butnem (MLB) located in another NMS, contained high gca for an ideal type of short plant. Crosses combination of Gelatik × LLBs, Gelatik × LLBfN, and MLB  × LLBn were vertex crosses on MS-1 and therefore, having high sca for the traits that mutually-correlated in the sector. In the other two MS sectors, the parents LLBn and LLBs were vertex genotype, so that crosses that have best sca were not found. Reciprocal effects can be viewed in some crosses, which LLBs × Gelatik was the cross combination with the highest reciprocal effects.

Abstract

This study was aimed to determine the proper dose of ash desiccant on maize seed stored for 30, 60 and 90 days. The design used was a Completely Randomized Factorial Design, with two factors and three replications.  The first factor was desiccant dose (D) : Do = 0 % (control), D1 = 5 % (12.5 g of seed weight), D2 = 10% (25 g of seed weight), D3 = 15 % (37 g of seed weight), D4 = 20 % (50 %g of seed weight), D5 = 25 % (62.5 g of seed weight).  The second factor was length of storage (S) : S1 = 30 day storage, S2 = 60 day storage and S3 = 90 day storage. The result show that use of desiccant only gave effect on the water content of seeds (12.31 %) and speed of seed growth vigor parameters (24.84 %).  Use of desiccant in 90 day storage were able to maintain water content of seeds (12.43 %), seed germination viability parameter (100 %), and vigor of seeds, which consisted of seed growth simultaneity (66.77 %) and seed growth speed (28.71 %).  The interaction between the use off ash desiccant and the length of storage had no effect on  viability and vigor of maize (Zea mays L) seeds but had an effect on their water content after storage (12.73%).

Abstract

Climate information/data of a region plays an important role in agricultural development in the region, because by utilizing the knowledge of the relationship between crops and climate, forecasts can be made of planting time, harvest time, drought (water deficit), flood (water surplus), pest attack and disease, determining the appropriate type of crop, and so on. The purpose of this study was to assess the presence of soil water and to determine the growing season in the Saumlaki area based on two rainfall conditions. This study used monthly rainfall data for 30 years (1990-2019) as well as other climatic data, such as air temperature, air humidity, sunshine duration and wind speed for 15 years (2005-2019). Computing of the water balance was carried out using Thornthwaite-Mather Method, and determination of growing season using soil water in optimum condition. Based on the calculation of the land water balance in the rainfall conditions there was a 75% chance of being surpassed by the groundwater deficit in the Saumlaki area which lasted for 6 months (June- November), whereas the value increases by 183 mm or 45.52% compared to normal conditions, that was from 402 mm to 585 mm. On the other hand, the groundwater surplus lasted only a month (May) and tended to decrease by 686 mm or 97.03% compared to normal conditions, from 707 mm to 21 mm. The optimum soil water content for plants in rainfall conditions was 75% chance of lasting for 6 months (January-June); 2 months shorter than the normal 8 months (December-July). In conditions of 75% chance of rainfall, the growing season in the Saumlaki area lasted for 7 months (December-June); a month shorter than the growing season in normal rainfall conditions of 8 months (December-July). Keywords: growing season, land water balance, rainfall, Saumlaki area ABSTRAK Informasi/data iklim suatu tempat berperan penting dalam pengembangan pertanian di wilayah tersebut, karena dengan memanfaatkan pengetahuan tentang hubungan antara tanaman dan iklim dapatlah dibuat prakiraan waktu tanam, waktu panen, kejadian kekeringan (defisit air), banjir (surplus air), serangan hama dan penyakit, penentuan jenis tanaman yang sesuai, dan sebagainya. Tujuan penelitian ini untuk menilai keberadaan air tanah dan menentukan musim tanam di Daerah Saumlaki pada dua kondisi curah hujan. Penelitian ini menggunakan data curah hujan bulanan selama 30 tahun (1990–2019) dan data iklim lainnya (suhu udara, kelembaban udara, lama penyinaran matahari kecepatan angin) selama 15 tahun (2005-2019). Perhitungan neraca air lahan menggunakan metode Thornthwaite-Mather, dan musim tanam ditentukan berdasarkan kondisi air tanah optimum. Berdasarkan perhitungan neraca air lahan pada kondisi curah hujan berpeluang 75% untuk dilampaui, defisit air tanah di daerah Saumlaki berlangsung selama selama 6 bulan (Juni-November) yaitu nilainya bertambah sebesar 183 mm (45,52%) dibandingkan kondisi normalnya, yaitu dari 402 mm menjadi 585 mm. Sebaliknya surplus air tanah berlangsung hanya sebulan (Mei) dan cenderung berkurang sebesar 686 mm (97,03%) dibandingkan kondisi normalnya, yaitu dari 707 mm menjadi 21 mm. Kadar air tanah yang optimum bagi tanaman pada kondisi curah hujan peluang 75% berlangsung selama 6 bulan (Januari-Juni); lebih pendek 2 bulan dibandingkan kondisi normalnya 8 bulan (Desember-Juli). Pada kondisi curah hujan peluang 75%, musim tanam di daerah Saumlaki berlangsung selama 7 bulan (Desember-Juni); sebulan lebih pendek dibandingkan musim tanam pada kondisi curah hujan normalnya 8 bulan (Desember-Juli).

Abstract

Climate change has an impact that includes extreme climate events such as El Nino. Experience in recent decades has shown that the El Nino climate anomaly has caused prolonged droughts. Peanut are susceptible to drought in part or all of its growth phases due to below-normal rainfall. This study aimed to describe the occurrence of extreme El-Nino rainfall on Kei Kecil Island, Maluku Province, and how much the El-Nino events affected the planting season and peanut production on Kei Kecil Island. This was carried out using the algebraic average technique for calculating the average (normal) rainfall and the FAO (1978) method for determining the growing season. The variables observed were rainfall data and peanut plant productivity data. Data were analyzed using simple regression analysis. The results of the study showed that the El Nino phenomenon generally took place in the period from April to November; mostly starting in April, May, June and September, October and November. Drought events on Kei Kecil Island did not always coincide with El Nino events, and El Nino events did not always cause drought or rainfall below normal. In 1993, 2003, 2007, and 2012 the amount of rainfall on Kei Kecil Island was below normal (<2,308 mm per year) but these years were not recorded as El Nino years. Whereas, 1994, 2009, 2014, and 2018 were recorded as El Nino years but did not cause drought or rainfall under normal conditions on Kei Kecil Island. During the last 30 years, this incident occurred 3 times, i.e. in 1991, 1997, and 2015. The results of the analysis of the growing season showed that the planting season on Kei Kecil Island under conditions of average (normal) rainfall lasted for 289 days or 9 months 16 days (November 1 to August 16). Meanwhile, the growing season when extreme El Nino rainfall occurred, lasted for 201 days or 6 months 20 days (November 1 to May 20). This indicated that when El Nino occurred on Kei Kecil Island, there was a shift in the growing season (ending sooner). The results of the regression analysis illustrated that the increase of the value of rainfall would increase the productivity of peanut crop. Keywords: El Nino phenomenon, growing season, peanut, productivity, rainfall ABSTRAK Perubahan iklim berdampak di antaranya terhadap kejadian iklim ekstrim seperti El Nino. Pengalaman dalam beberapa dekade terakhir ini menunjukkan bahwa anomali iklim El Nino telah menyebabkan kekeringan berkepanjangan. Kacang tanah rentan oleh deraan kekeringan pada sebagian ataupun seluruh fase pertumbuhannya akibat curah hujan yang di bawah normal. Penelitian ini bertujuan untuk mempelajari kejadian curah hujan ekstrim El-Nino di Pulau Kei Kecil, Provinsi Maluku, dan seberapa besar kejadian El-Nino mempengaruhi musim tanam dan produksi kacang tanah di Pulau Kei Kecil. Ini dilaksanakan dengan menggunakan metode teknik rata-rata aljabar untuk perhitungan curah hujan rata-rata (normal) dan metode FAO (1978) untuk penentuan musim tanam. Variabel yang diamati adalah data curah hujan dan data produktifitas tanaman kacang tanah. Data dianalisis menggunakan analisis regresi sederhana. Hasil penelitian menunjukkan fenomena El Nino umumnya berlangsung dalam periode April hingga November; terbanyak mulai bulan April, Mei, Juni dan September, Oktober dan November. Kejadian kekeringan di Pulau Kei Kecil tidak selalu bersamaan dengan kejadian El Nino, dan kejadian El Nino tidak selalu menyebabkan kekeringan atau curah hujan di bawah normal. Pada tahun 1993, 2003, 2007, dan 2012 jumlah curah hujan di Pulau Kei Kecil berada pada kondisi di bawah normal (<2.308 mm per btahun) tetapi tahun-tahun tersebut tidak tercatat sebagai tahun-tahun El Nino. Sementara itu, tahun 1994, 2009, 2014, dan 2018 tercatat sebagai tahun-tahun El Nino tetapi tidak menyebabkan kekeringan atau curah hujan di bawah kondisi normalnya di Pulau Kei Kecil. Selama periode 30 tahun terakhir kejadian ini berlangsung selama 3 kali, yaitu pada tahun 1991, 1997, dan 2015. Hasil analisis musim tanam menunjukkan bahwa musim tanam di Pulau Kei Kecil pada kondisi curah hujan rata-rata (normal) berlangsung selama 289 hari (1 November sampai dengan 16 Agustus; 9 bulan 16 hari). Sedangkan musim tanam ketika curah hujan ekstrim El Nino berlangsung selama 201 hari (1 November sampai dengan 20 Mei). Hal ini mengindikasikan bahwa ketika El Nino berlangsung di Pulau Kei Kecil, akan terjadi pergeseran musim tanam (berakhir lebih cepat). Hasil analisis regresi menggambarkan bahwa penigkatan nilai curah hujan akan menigkatkan produktivitas tanaman kacang tanah.

Abstract

This study aims to determine the effect of application and timing of Top G2 liquid organic fertilizer on the growth and yield of hotong plants. The research design was a Randomized Block Design with two factorials, namely the concentration of Top G2 liquid organic fertilizer and application time, and each treatment was repeated 3 times. The results showed that the application of liquid organic fertilizer TOP G2 had no significant effect on plant height and number of leaves at 8 WAP, as well as panicle weight g, panicle length cm, weight 1000 seeds g, fresh root weight g and plant dry weight g. While the real weight of the plant fresh and very significant on the dry weight of the roots. The time of administration of 8 WAP showed that plant height and panicle weight were significant and leaf number, panicle length was cm, seed weight was 1000 g, root fresh weight was g, plant fresh weight was g, and plant dry weight was very significant. Meanwhile, root dry weight was not significant. The interaction of 8 WAP was not significant on plant height, number of leaves, panicle weight g, panicle length cm, root fresh weight g, plant fresh weight g, root dry weight g, and plant dry weight g. While the interaction is very significant at the weight of 1000 seeds.

Abstract

The determination of the growing season is closely related with the climate change that occurs in a region The study aims to determine the trend of changing the growing season in the Batabual Area, changes in the growing season that occur due to changes in rainfall, and alternative planting patterns in Batabual region based on changes in the growing season that occur. Data analysis consisted of (1) determining the climatic conditions of the region using the Algebraic average method from monthly rainfall data from the Buru meteorological climate station for the last 30 years 1991-2020 and (2) determining the planting season using the FAO method (1978). The results showed that based on average rainfall data, the growing season lasted for 10 months and 19 days (November to September 19 of the following year). However, if you use rainfall with a 75% chance of being exceeded, the growing season period only lasts for 8 months and 21 days (December – July 21 of the following year).

Abstract

Cropping patterning is an farming practice to obtain maximum production taking into account climatic conditions, soil and types of crops cultivated. This research, which was carried out in the Amahai Region, aimed to: (i) describe extreme climate events and (ii) determine the growing season and cropping patterns of food crops based on the length of the growing season available in the region. The analytical methods used consisted of: (i) determining extreme rainfall based on BMKG standards and ENSO History data, (ii) determining the planting season using the FAO method, and determining cropping patterns in conditions of extreme rainfall. The results showed that a very extreme El Nino event caused a decrease in rainfall in the Amahai region by 1,444 mm or 54% of its normal condition, on whereas a very extreme La Nina event caused an increase in rainfall by 1,528 mm or 60% of its normal condition. The growing season in the Amahai region under conditions of average (normal) and La Nina rainfall is throughout the year (12 months), and under conditions of extreme El Nino rainfall, the growing season lasts for 8 months and 26 days, 96 days shorter than normal conditions. In conditions of extreme El Nino rainfall, the cropping patterns that can be applied are sequential, monoculture, and polyculture/ intercropping.

Abstract

The growth of mustard plants is influenced by the availability of nutrients through the application of fertilizers. Manure and sea mud are one type of biological fertilizer. The study aims to determine the optimal dose of sea mud and manure for the growth and production of mustard plants. The study design was a randomized group design consisting of 2 factors and repeated 3 times. The first of Sea Mud treatment (L) consists of levels, namely: L0 = Control; L1=500 g, L2= 750 g. L3 1000 g. The second factor is that the dose of manure consists of levels, namely: P0=without manure; P1=120 g, P2=160 g: and P3 = 200g. The results showed that L3 treatment was able to increase plant height, while the number of leaves was best in L2 treatment. This treatment was also able to increase the number of leaves, fresh weight and dry weight but between L2 and L3 treatments did not differ markedly. P3 manure treatment is able to increase the best number of leaves, while fresh weight is best P2 treatment. The interaction between treatments only occurred in plant height and leaf area parameters at 17 HST observations.

Abstract

Cassava (Manihot esculenta Crantz) which belongs to the Euphorbiaceae family is a plant that has long been known and cultivated by the people of Indonesia. The process of plant adaptation will cause changes in the shape, size, color and yield of plants. The Cassava breeding program in Indonesia aims to assemble varieties with a high yield, tolerance to major pests and diseases, non-intensive branching, good tuber shape, tolerance to certain soil and climatic conditions, and early maturity. This study aimed to obtain the morphological characters of several varieties of cassava in the Leihitu District. This research was conducted in Leihitu District, Central Maluku Regency, eight villages were used as research locations, namely Morella Village, Mamala Village, Hitu Messeng Village, Hitu Lama Village, Wakal Village, Hila Village, Kaitetu Village and Seith Village. This study used a descriptive analysis method. The results showed in 8 villages in Leihitu District, we found 8 different varieties of cassava plants, namely Inggris, Bistein, Keras/Pahit, Bubur/Lunak, Sukabumi, Kapok and Mentega. The diversity of cassava varieties was very high in Kaitetu Village, whereas the diversity was low in Morella Village and Mamala Village. Based on the dendrogram formed, there were 2 clusters, 3 clusters, 4 clusters, 5 clusters, 6 clusters, and 7 kinship clusters with a kinship distance scale of 5, 10, 11, 13, 18, and 25.
