Abstract

Analysis of Drought Level to Reduce Risk of Food Crop Harvest Fails in Banten ProvinceABSTRACT. Climate is one of the most important factor to the success of the agriculture production. Climate variability such as season change, lack or excess of water, are sample examples of climate factors which limit agriculture production. Planning agriculture activities which involving climate factors as one of the consideration will reduce crops production failure. This research conducted to identified the potency of drought at Banten Province by consecutive dry days analysis at 5, 10, and 15 continuous days or more. The result showed that the potency of drought at northern Banten is higher compared to middle and southern Banten. This was showed by the high opportunities of DHK = 5, 10, and 15 continuous days or more, as big as 0,65, 0,46, and 0,28. The lowest potency of drought occur at southern Banten with opportunities of DHK≥ 5, 10, and 15 continuous days or more, each as big as 0,43, 0,30, and 0,18.

Solar Radiation Use Efficiency, Growth and Soba (Fagopyrum esculentum Moench.) Production in Ciawi BogorABSTRACT. Soba (Fagopyrum esculentum Moench) is potential alternative food source because of its chemical contents which are not so different from other main food sources. In its agronomical development, intensive and sustain research are needed to study solar radiation uses efficiencies, growth and yield of soba under different population an time planting. This research conducted from April to August 2000 at BPLP Ciawi – Bogor experiment station 415 meter top of sea level, 106 51 BT and 06 38 LS. Unit of research arranged by factorial completely randomized block design. The population factor consist of 3 level : 200 plants m-2 (P1), 160 plants m-2 (P2) and 133 plants m-2 (P3), and time of planting also consist of 3 levels : on April (T1), May (T2) and June (T3). Solar radiation uses efficiency at early growth to weeks after planting was higher at high population compared to low population, but after 5 weeks of planting or when maximum efficiencies, its higher on P2 compared P3 and P1. This showed that when grain filling and maturing, it is more intensive on low population then high population, however the anova for two factors at maximum efficiencies did not showed significant differences. Growth and yield of soba is better on high population compare to low population. This because on high population the microclimate condition and water availability is more adequate then on low population. There was no significant different on 1000 grain weight caused by two factors. For total yield P1 172,1 gm-2 was highest and significantly different then P2 143,6 gm-2 and P3 123,9 g m-2. Production cause by time of planting did not showed significant different between T1 and T2 but it did on T3.

Merrill)ABSTRACT.  The aims of this study were to determine the effect of varieties and spacing and its interaction on growth and yield of soybeans. Randomized Completely Block Design  (RCBD)  3x3 factorial with three replications was applied. Factors studied were varieties: Anjosmoro, Grobogan, and Kipas Merah, and spacing factor of 20 cm x 30 cm, 20 cm x 40 cm, and 40 cm x 40 cm. Variables observed were soybean plant height age of 15, 30 and 45 DAP, the number of pods per plant, number of pods per plant and weight seeds per plant. The results showed varieties effected plant height on 15 and 30 DAP significantly, which higher than Grobogan and Anjosmoro. Meanwhile spacing simply effect plant height on 45 DAP significantly. The highest plant found on 20 cm x 20 cm spacing. There were interaction significantly between varieties and spacing on the number of pods per plant and weight dry seed per plant. The best result were obtained on a variety Anjosmoro with spacing of 40 cm x 40 cm.

Abstract

ABSTRAK. Iklim merupakan salah satu faktor penting dalam keberhasilan produksi pertanian. Variabilitas iklim, seperti perubahan musim, kekurangan atau kelebihan air merupakan beberapa contoh faktor iklim yang merupakan faktor penghambat produksi pertanian tropis. Penelitian ini dilakukan untuk menganalisis perubahan dan lamanya musim kemarau, musim hujan, periode transisi, dan pola perkembangan serta waktu tanam padi berbasis analisis data curah hujan. Analisis perubahan musim dilakukan dengan membandingkan data curah hujan bulanan antara periode 2000 – 2009 dan 1990 – 1999, yang dipisahkan oleh musim kemarau, musim hujan, dan periode transisi dengan menggunakan Beda Nyata Terkecil yang dikoreksi dengan kriteria oldeman. Penentuan potensi waktu tanam diawali dengan analisis neraca air lahan dengan menggunakan metode Thornwaite dan Mather, yang disesuaikan dengan periode waktu tanam dengan kandungan lengas tanah 50% dari air tersedia. Analisis perubahan musim menunjukkan bahwa tidak ada perubahan musim kemarau dan hujan selama periode 2000 – 2009 dibandingkan dengan 1990 – 1999, namun ada pergeseran pada awal musim kemarau dari bulan Juni menjadi Mei dengan durasi 4 bulan. Untuk pola dan waktu tanam, dari 4 kecamatan sentra produksi padi yang ditinjau potensi masa tanamnya antara 4 bulan – 4,25 bulan dengan awal waktu tanam jatuh awal bulan Oktober. Pola tanam yang dianjurkan apabila tidak tersedia irigasi adalah padi pada awal musim tanam pertama dan palawija musim tanam kedua.Analysis of Season Changes and Development of Paddy Planting Pattern Based on Rainfall Data in Aceh BesarABSTRACT. Climate is one of the most important factor to the success of agriculture production. Climate variability such as season change, lack or excess of water, are some examples of climate factor which limit agriculture production in the tropics. This research conducted to analyze the changes and duration of dry season, rain season, and transition period, and develop pattern and planting time of rice crop base on rainfall data analysis. Season change analysis conducted by comparing monthly rainfalls data between 2000-2009 period and 1990-1999 period, where the splitting of dry season, rain season and transition period conducted with LSD (Least Significant Difference), corrected with Oldeman’s criteria. Planting time potency assumed by Thornwaite and Mather water balance analysis approachment, and it is set up that the planting time period is the water holding capacity 50% from available water. The season change analysis showed that there is no change to dry and rain season duration on 2000-2009 period compared to 1990-1999 period, but there is shifting in dry season beginning from June to May with 4 months constant duration. The best planting pattern and planting time, from 4 subdistrict of rice crop main production observed, planting time potency between 4 to 4,25 month with planting time at the beginning of October. Without irrigation, planting pattern suggested is rice crop at the beginning of growing periods and palawija at the end of growing periods.
