PENINGKATAN PERTUMBUHAN DAN PRODUKSI KEDELAI MELALUI KOMBINASI PUPUK ORGANIK LAMTOROGUNG DENGAN PUPUK KANDANG
No full textResponse of plant on agroinputs such as organic fertilizer is different, depending on cultivar. Nutrient composition of organic fertilizer is also varied from one to another. The cultivar of Kipas Putih and Anjasmara were studied. The growth and yield of soybean were significantly affected by cultivar and organic fertilizer, composted from manure and green manure using EM-4. The growth and yield of Kipas Putih were significantly better than those of Anjasmara. Fertilization with 12.5 ton/ha of organic matter also increased growth and yield of soybean
RESPONS BEBERAPA VARIETAS PADI TERHADAP WAKTU PEMBERIAN BAHAN ORGANIK PADA METODE SRI
No full textThe objective of study was to determine response of three varieties of rice to timing of providing organic fertilizer on SRI system. The results showed that the timing of providing organic materials exerted a significant effect on grain weight per hill and production per hectare, but no significant effect on variables of other rice growth and production. Provision of organic matter at planting date and a week after planting date gave better grain weight per hill and production per hectare than a week before planting date. These results were consistent for all the tested rice varieties, i.e. Ciherang, Pandan Wangi, and Angke. However, to some extent, Pandan Wangi was the best
ANALISIS KORELASI DAN KOEFISIEN LINTAS ANTAR BEBERAPA SIFAT PADI GOGO PADA MEDIA TANAH MASAM
No full textA study was conducted to study correlation between some characters of upland rice and path coefficient analysis, which will be helpful for further selection process to improve upland rice in acid soils. The results of evaluation of lines for Al-tolerant in acid soils revealed that number of tillers and filled grain per panicle were inherited with high heritability and directly affected grain weight and contributed indirectly to the correlation between grain weight and other characters. However, indirect selection through number of tillers and filled grain per panicle was less efficient than direct selection through grain weight
PENGARUH PEMOTONGAN UMBI BIBIT DAN JENIS PUPUK ORGANIK TERHADAP PERTUMBUHAN DAN HASIL BAWANG MERAH
No full textThe objective of the research was to find out a suitable bulb slicing and kind of organic fertilizer for a maximum growth and yield of onion. This research applied a randomized complete block design (RCBD), 3 by 3 with 3 replications. Factors observed were bulb slicing and kinds of organic fertilizer. Bulb slicing consisted of no cut, cut of one-third, and cut of one-fourth of onion bulbs. Organic fertilizer consisted of compost, manure of cow and manure of chicken. Variables observed were plant height, a number of onion tillers per bunch, a number of onion bulbs per bunch, wet and dry weight of bulbs per bunch. Result showed that bulb slicing significantly affected a number of onion tillers per bunch at 30 day after planting (DAP), 45 DAP, and a number of onion bulbs per bunch. However, bulb slicing did not significantly affect plant height at 15 DAP and dry weight of bulb per bunch. The best growth and yield was found at cut of one-fourth of the bulb. Organic fertilizer showed a significant effect on a number of bulbs per bunch but did not exert a significant effect on other variables. More bulbs per bunch were achieved at compost. There was no significant interaction between bulb slicing and organic fertilizer type on growth and yield of onion
PERUBAHAN ANATOMI DAN KANDUNGAN OLIGOSAKARIDA PADA BENIH REKALSITRAN Avicennia marina AKIBAT PERBEDAAN LAJU PENGERINGAN
No full textABSTRACTThe objective of this study was to evaluate anatomical changes and oligosaccharide content of recalcitrant seed Avicennia marina at various drying rate i.e. fast, medium and slow drying. Oligosaccharide content was determined, and anatomical embryonic axes was observed at various times during desiccation. The result showed that moisture content of A. marina seed was 60.75-64.67% at shedding. The highest ratio of (raffinose + stachyose) / sucrose was 0.41, indicating that embryonic axes were more tolerant to desiccation than cotyledon. Anatomical observation of embryonic axes showed that there was radicle damage due to medium and slow drying treatment
PENGARUH LAMA PENYIMPANAN INANG PADA SUHU RENDAH TERHADAP PREFERENSI SERTA KESESUAIAN INANG BAGI Trichogrammatoidea armigera NAGARAJA
No full textThe purpose of this study was to investigate effect of storage period length under low temperature on host preference and host suitability for egg parasitoid, Trichogrammatoidea armigera. In this study, Corcyra cephalonica eggs were used as the alternative host. The result showed that the storage of host eggs under low temperature for 1.5 to 3 hours was able to delay host egg hatching until the day 5, however, for normal host eggs the hatching time was started at day 4. This method did not exert a negative effect on host preference and host suitability for parasitoid T. armigera. The rate of parasitism on the stored hosts was more than 90%, and it was not significantly different from the normal host. T. armigera progeny (offspring) emerged from the stored host was also very high (more than 100%). The result also showed that the percentage of T. armigera female progeny emerged from stored hosts higher than the normal host. The female progeny emerged from normal host was 51%, while from hosts stored under low temperature for 1.5, 2.0, 2.5 and 3 hours were 69,49%, 66,03%, 66,16% and 71,10%, respectively. The results indicated that the stored host eggs under low temperature (1 4 oC) for 1,5 3,0 hours did not kill the host embryo, but only delay the hatching times. Therefore, the availability of a sufficient number of fresh hosts could be maintained in the laboratory, so that the efficiency of mass rearing program of T. armigera parasitoid could be increased
KONFIRMASI TEKNIK PENGAMBILAN SAMPEL UNTUK SELEKSI LAJU DAN MASA PENGISIAN BIJI TANAMAN JAGUNG
No full textConfirmation of Sampling Technique for Selection of Rate and Filling Periode Duration in CornTeuku Mahmud Fakultas Pertanian Unsyiah, Darussalam Banda AcehABSTRACTKernels of the original (C0) plus fifth cycle (C5) of a maize (Zea mays L.) synthetic, divergently selected for long and short effective filling period (EFP) or high and low dry matter accumulation rate (DMAR), were evaluated by two different sampling procedures. The objectives were to evaluate single plant vs. multiple plant measurement procedure for EFP and DMAR, plus changes the selection traits, physiological and morphological characteristics, and plant yield. The two sampling techniques and all data analysis procedures resulted in a similar ranks of kernel size, DMAR, and EFP. The best estimate of maximum kernel size was at black layer maturity. The nonlinear procedure estimated EFP better than did other procedures. Compared to C0, DMAR was increased 31.5% and reduced 36% for the C5 high and low DMAR subpopulations, respectively. The kernel size of high and low DMAR in C5 differed by 105.4%. Long EFP selections tended to decreased DMAR. Compared to C0, EFP was increased 11.3% and reduced 8.8% for the C5 long and short EFP subpopulations, respectively. The EFP differences between long and short EFP selections was 22.1%. Duration differences occured almost exclusively in the late lag phase. Yield of the long EFP and high DMAR selections were equal to C0 but significantly greatert than short EFP and low DMAR selections. Yield was positively correlated with kernel size, DMAR, and EFP. Kernel size was correlated with DMAR and yield. From this experiment one might infer that selection for long EFP and high DMAR should increase yield

Units of research arranged according to completely randomized design (CRD) with 3 replicates. The factor of fruit ripening stadiums consisted of 3 levels: before, in and after physiological maturity, and also the factor of seed position inside the fruit consisted of 3 levels: both ends and at the middle of the fruit. Observations conducted to the potency to germinate, Germination capacity, rate of germination and uniformity of germination. The results showed that germination capacity, rate of germination and uniformity of germination were highly significant affected and potency to germinate was significantly effected by fruit ripening stadiums. The highest jackfruit seed viability was found from physiological matury stadium. Germination capacity and rate of germination also highly significantly affected by seeds position inside the fruit, but not significant on the potency to germinate and uniformity of germination. The highest jack fruit seeds vibility come from the middle of the fruit. There was a very significant of both factors on seed rate of germination, significant interaction on germination capacity, and not significant to other parameters
