Production of mungbean has been increasing in Ethiopia because of its high importance as a source of protein and foreign exchange earnings. Determination of appropriate plant density for the varieties of mungbean can increase its productivity. Therefore, an experiment was conducted to determine the effect of inter and intra row spacing on growth, yield components and yield of mung bean varieties under irrigation. The treatments consisted of factorial combinations of three inter row spacing (30, 40, and 50 cm), three-intra row spacing (5, 10 and 15 cm) and two mungbean varieties (N-26 and MH-97) laid out in randomized complete block design with three Replications. The main effect of varieties, inter row spacing and intra row spacing was highly significant and significant on plant height, secondary branch and where the longest plant height (41.71 cm) was for variety MH-97 and from 5 cm intra row spacing, respectively and maximum number of secondary branch was recorded for variety MH-97 (8.91) and from 15cm intra row and 50cm inter row spacing, respectively. The interaction effect of the variety, inter and intra row spacing was highly significant on number of primary branch per plant, number of pod per plant and crop stand count percentage where the highest number of primary branches (7.00) was recorded from variety MH-97 at 50 cm inter row spacing and highest number pods per plant (30.15) were recorded for variety MH-97 at 40 cm inter row and (31.34) at 15cm intra row spacing. Where the highest crop stand count at harvest were recorded from variety MH-97 (97.00%) at 40 cm inter row spacing .The main effect of inter row spacing and intra row spacing were highly significant and significant on above ground dry biomass and the highest above ground dry biomass at inter row spacing of 30 cm ( 5968.8 kg ha-1) and intra row spacing 5cm 6145.9 kg ha-1).The main effect of variety, inter-row and intra-row spacing were highly significant on harvest index and grain yield where the highest harvest index was from variety MH-97 (20.91%), inter row spacing of 40 cm which give (21.18%) and intra row spacing 10 cm which give (20.30%) and the highest grain yield from Variety MH-97 (1117.94 kg ha-1), inter row spacing 40 cm (1213.75 kg ha-1) and intra row spacing 10 cm which give (1151.67 kg ha-1) However, this tentative generalization based one season at one location requires further studies over years and locations to give a valid recommendation.

Penelitian yang bertujuan mengetahui pengaruh dosis pupuk kandang ayam pedaging dan pupuk hayati BiotamaxTM serta interaksinya terhadap pertumbuhan dan hasil petsai dilaksanakan di Desa Selat, Kabupaten Buleleng, Bali pada bulan November - Desember 2018. Rancangan percobaan yang digunakan adalah rancangan acak kelompok (RAK) faktorial, terdiri atas dua faktor. Faktor pertama adalah dosis pupuk kandang ayam pedaging (A), terdiri atas 3 tingkat, yaitu kontrol (A0), dosis 15 ton.ha-1 (A1), dan 30 ton.ha-1 (A2). Faktor ke dua adalah frekuensi pemberian pupuk hayati dengan empat tingkat, yaitu kontrol (B0), pemberian sekaligus yaitu 7 hari sebelum tanam dengan dosis 0,09 g.petak-1 (B1); frekuensi pemberian 2 kali yaitu 7 hari sebelum tanam dan 14 hari sesudah tanam (hst) dengan dosis setiap pemberian 0,045 g.petak-1 (B2); frekuensi pemberian 3 kali yaitu 7 hari sebelum tanam, 14 hst dan 28 hst dengan dosis setiap pemberian 0,03 g.petak-1 (B3). Hasil penelitian, frekuensi pemberian pupuk hayati BiotaMaxTM sekaligus, memberikan berat kering oven tajuk per tanaman terberat, yaitu 9,39 g. Perlakuan dosis pupuk kandang ayam pedaging dosis 30 ton.ha-1 (A2), menghasilkan berat kering oven tajuk per tanaman terbaik yaitu 9,26 g. Hubungan antara dosis pupuk kandang ayam pedaging dengan berat kering oven tajuk per tanaman menunjukan hubungan linier, yaitu y = 0,0608x + 7,2483 (R2=32,53). Berat ekonomis per hektar terbaik didapatkan pada pemberian dosis pupuk kandang ayam pedaging 30 ton.ha-1 (A2), yaitu seberat 30,10 ton.ha-1. Hubungan antara dosis pupuk kandang ayam pedaging dan berat ekonomis per hektar menunjukan hubungan linier, yaitu y = 0,3247x + 21,699 R2=59,88%. Frekuensi pemberian pupuk hayati BiotaMaxTM sekaligus yaitu 7 hari sebelum tanam dengan dosis 0,09 g.petak-1 (B1) memberikan berat ekonomis per hektar terberat, yaitu 28,21 ton.ha-1. Kombinasi dosis pupuk kandang ayam pedaging dan frekuensi pemberian pupuk hayati BiotaMaxTM berpengaruh tidak nyata (p≥0,05) terhadap pertumbuhan dan hasil petsai.DOI:https://doi.org/10.37637/ab.v2i2.383

Penggunaan mutagen kimiawi kolkisin sebagai bahan untuk menginduksi poliplodi pada tanaman, memberikan peluang bagi peningkatan produksi beras hitam yang sampai saat ini produktivitasnya masih rendah. Hal ini berkaitan dengan banyaknya manfaat beras hitam untuk kesehatan, sehingga menyebabkan meningkatnya permintaan konsumen. Perlakuan berbagai dosis kolkisin diharapkan mampu meningkatkan dosis gen, sehingga tanaman mimiliki penampilan dan produksi yang lebih baik. Tujuan dari penelitian ini adalah untuk mengidentifikasi perubahan fenotip pada genotip padi beras hitam (Oryza sativa L.) var Cempo Ireng akibat perlakuan berbagai dosis kolkisin. Penelitian menggunakan desain petak tunggal dengan 4 perlakuan konsentrasi colchicine (0, 250, 500 dan 750 ppm) pada 2 genotipe padi beras hitam (Ungaran dan Cempo Ireng). Analisis data menggunakan independent t-test level signifikan 5%. Hasil penelitian menunjukkan perlakuan kolkisin dengan konsentrasi 750 ppm efektif dalam menginduksi mutasi sehingga menyebabkan perubahan fenotip pada sebagian besar karakter tanaman pada kedua genotip.

In Ethiopia, a great variety of diseases affects faba bean production. However, gall forming faba bean new disease has become a very serious disease that seriously affected faba beans producing areas of Wollo. This prescalling up of integrated faba bean gall technology has been conducted at Meket and Wadla woredas of north Wollo in 2017/18 to create wider demand on the management of gall disease and to enhance integrated gall disease management technology dissemination. The study areas were selected purposively due to high infestation of the disease. A total of 32 farmers were selected based on a voluntary base. Adjacent farms of 5.7 ha at Wadla and 3 ha at Meket was selected and clustered accordingly. Integrated disease management i.e seed dressing with 300 gm Baylaton/100Kg seed, improved varieties and hand weeding were applied as a package for the control of the disease. Dosha with chemical gave an average gain yield of 2.2 tons/ha at Meket whereas Wolki with chemical gave an average grain yield of 2.5 tons/ha at Wadla woreda. However, the local variety with farmers’ practice gave an average grain yield of 100 kg/ha and 900 kg/ha at Wadla and Meket woredas respectively. The result of economic analysis also indicate that the technology is by far advantageous than the local variety and practice. So, the technology should be further disseminated to other hot spot areas of faba bean gall diseases.

Sweet orange (Citrus sinensis L.) is an important fruit produced and consumed worldwide and it’s an excellent source of vitamin C. However, citrus industry in Ethiopia is at an infant stage; which is particularly due to shortage of improved and adapted cultivars and their distribution. Considering these, six sweet orange cultivars were evaluated to select adapted, high yielding and quality cultivar/s. Different growth, phenological, yield and yield component data were collected and analyzed using SAS. Days to maturity was also highly significantly (p<0.01)) affected by cultivars in 2017 cropping year. Fruit weight without rind (flesh weight) and juice weight were highly significantly (p<0.05) affected by cultivars in 2018 harvesting year. Marketable yield, unmarketable yield, and total yield tree-1 were significantly affected by cultivars in both 2017 and 2018 harvesting year. O. Valencia is late matured cultivars which took 1622 days from planting to first harvest. While, P.W.N. is early matured cultivars with average number of days of 1104 from planting to first harvest. In 2017, Hamlin, gave the highest marketable fruit yield tree-1 (68.61 kg) and total yield tree-1 (68.94kg). Jaffa gave significantly the maximum marketable fruit yield tree-1 (197.24 kg) and total yield tree-1 (198.81 kg) in 2018 cropping year. In 2019 harvesting year, Hamlin gave the highest marketable (63.3 kg) and total (64.02 kg) fruit yield tree-1. In average Jaffa and Hamlin gave the maximum marketable fruit yield tree-1 from the three consecutive harvesting years with mean value of 95.38 kg and 72.24 kg respectively. So, in Raya Azebo, and other areas having similar agro-ecologies Jaffa and Hamlin cultivars are recommended. Further, studying the nutritional content and water requirements of these cultivars are suggested.
