Abstract The main goals of this study were to evaluate the agronomic performance of wheat mutant lines; to detect the effect of genotype, location and different fertilizer levels on analysed traits; to assess seed and feed quality; and to select best performing mutant lines for dual-purpose growing. Ten wheat mutant lines were sown on two locations in Macedonia, for evaluation of their agronomic performance. At both locations, grain yield, straw mass, harvest index, nitrogen use efficiency, nitrogen and protein content in seed and straw, neutral detergent fibre and acid detergent fibre in the straw were determined. In order to classify the genotypes based on all analysed traits, two-way cluster analysis was applied. According to their overall performance, at both locations and with the three different fertilization treatments, the mutant lines were classified in two main groups. The first cluster consisted of mutants 5/1-8, 2/2-21, 4/2-56 and 2/1-51, characterized by very high values for seed yield, straw yield and harvest index, and high to moderate values for all other traits. Only 4/2-56 had very low values for N and protein content in the seed. One mutant line, 6/2-2, did not belong to any of the groups and differed from all other genotypes based on its very low seed and straw yield and very high values for nitrogen and protein content in the straw and neutral detergent fibre. All other mutants belonged to the second group, with low to moderate yield and moderate to high values for the other traits. Mutant lines with the highest seed and straw yield, as well as the best quality of seed and straw under different management systems, were identified and after additional evaluation will be submitted for official variety registration.

Growth-stage-based alfalfa harvest treatments were imposed on a 2-yr-old Beaver alfalfa stand in 1992 to determine the effect of harvest treatments on yield and quality. By 1993, alfalfa cut at the vegetative stage or prebud stage contained 25% dandelions by weight. At these stages weeds lowered crude protein content in the total forage relative to pure alfalfa. Weed contents were similar and less than 1% by weight in forage cut at prebloom and later stages. Crude protein and fibre contents were similar in total forage and pure alfalfa at prebloom and later stages.

Deficiency of metals, primarily Fe and Zn, affects over half of the world’s population. Human diets dominated by cereal products cause micronutrient malnutrition, which is common in many developing countries where populations depend heavily on staple grain crops such as wheat, maize, and rice. Biofortification is one of the most effective approaches to alleviate malnutrition. Genetically stable mutant spring wheat lines (M7 generation) produced via 100 or 200 Gy gamma treatments to broaden genetic variation for grain nutrients were analyzed for nutritionally important minerals (Ca, Fe, and Zn), their bioavailability, and grain protein content (GPC). Variation was 172.3–883.0 mg/kg for Ca, 40.9–89.0 mg/kg for Fe, and 22.2–89.6 mg/kg for Zn. In mutant lines, among the investigated minerals, the highest increases in concentrations were observed in Fe, Zn, and Ca when compared to the parental cultivar Zhenis. Some mutant lines, mostly in the 100 Gy-derived germplasm, had more than two-fold higher Fe, Zn, and Ca concentrations, lower phytic acid concentration (1.4–2.1-fold), and 6.5–7% higher grain protein content compared to the parent. Variation was detected for the molar ratios of Ca:Phy, Phy:Fe, and Phy:Zn (1.27–10.41, 1.40–5.32, and 1.78–11.78, respectively). The results of this study show how genetic variation generated through radiation can be useful to achieve nutrient biofortification of crops to overcome human malnutrition.

We hypothesised (i) that sheep grazing a monoculture of tedera (Bituminaria bituminosa (L.) C.H. Stirton var. albomarginata and var. crassiuscula) would not show signs of photosensitisation or ill health, and (ii) that when given free grazing choice they would show a repeatable preference for certain accessions of tedera related to their chemical composition. We tested this by grazing a group of young merino wethers on a monoculture containing seven accessions of tedera for 21 days. General health was assessed via daily visual checks for skin pinkness on the nose and ears, weekly measures of liveweight, condition score, and blood analysis compared with a group of control sheep fed wheaten hay ad libitum. The Chesson–Manly selection index was used to examine the relative preference of sheep for the seven accessions of tedera over the 21 days. Each accession of tedera was sampled weekly to estimate the dry matter on offer, and these samples were also analysed for crude protein, neutral detergent fibre, acid detergent fibre, in vitro digestibility, water soluble carbohydrates, minerals, and concentrations of the furanocoumarins psoralen and angelicin. None of the sheep showed any signs of ill health, with all blood parameters being within the normal reference range. All sheep gained weight and body condition over the 21 days. The difference in the rate of gain in condition score in favour of the sheep grazing tedera over the 21 days (0.014 v. 0.002 unit/sheep.day) was significant (P < 0.001). Sheep showed repeated preference for accessions T31 and T43 (α >0.143). Nutritive value of all accessions of tedera was high. However, only acid detergent fibre and neutral detergent fibre affected the relative preference of the sheep (P < 0.05) and they were only weakly correlated (r2 = 0.208 and 0.165, respectively). We conclude that there are accessions of tedera that are preferred by sheep that could be used to fill the autumn feed gap experienced in the south of Western Australia without any risk to the health of the sheep.

To compare the effects of varying seeding rate on the agronomic performance, phenology and seed quality of hybrid and conventional summer rape cultivars, four hybrid and two conventional summer rape cultivars were seeded at 1.5, 3.0, 4.5, 6.0 and 9.0 kg ha−1 at two locations for 3 yr. The hybrid cultivars were, very importantly, 24% higher yielding and produced 50% more total dry matter than the conventional cultivars. The hybrid cultivars were, on average, 1.3% lower in seed oil content, 1.0% higher in seed protein content and equal in sum of oil and protein in the seed compared with the conventional cultivars. The hybrid cultivars were on average, 1.3 d later to 50% flowering and 1.1 d later to maturity than the average for the conventional cultivars, (i.e., equal or earlier to flowering and maturity than Regent). The hybrid cultivars were also 3.9% lower in harvest index and 1.3 ppm lower in chlorophyll content than the conventional cultivars. In spite of these differences, there were no significant cultivar-by-seeding-rate interactions, indicating that the hybrid and conventional cultivars responded similarly to varying seeding rate. Lodging, days to 50% flowering, days to maturity, harvest index, survival, oil content and protein content displayed significant linear responses to varying seeding rate. Stand at maturity, seed yield and total dry matter production displayed significant linear and quadratic responses to varying seeding rate. Varying seeding rate had no effect on seed formation period, the sum of oil and protein content, or chlorophyll content. A seeding rate of 6 kg ha−1 maximized seed yield for both hybrid and conventional summer rape cultivars.Key words: Brassica napus, canola, seed quality, agronomy, phenology

This time, rubbish is a very serious environmental problem for the people of Kampung Baru, Sampora Village, Tangerang. The increase in population results in an increase in the amount of rubbish. According to data, rubbish production in Tangerang in 2020 reached 22,873 tons, while the rubbish handled was only around 937 tons (4%).This problem needs to be solved immediately. Rubbish generated by households can be in the form of organic or inorganic. If rubbish is not managed properly, it can damage the surrounding environment.The method   used to solve the problem of organic rubbish can be done through bioconversion of organic rubbish into maggot.Organic rubbish is often considered safe because it is easily biodegradable, even though organic rubbish has the potential to damage the environment, This method has advantages, because during the bioconversion process it does not cause unpleasant odors Bioconversion of organic rubbish can be a rubbish management solution that can be offered to the residents of Kampung Baru..Every 1 kg of maggot requires 2 kg of organic rubbish/hour as food. The speed of maggot using organic rubbish  as feed can be an alternative to reduce the amount of organic rubbish.Maggot that is ready to be harvested has a very high protein content, so it can be used as feed for catfish or  poultry.Catfish fed with maggot as feed, at the age of 100 days, each kilogram contained 6 catfish, while catfish fed only with pellets, at the age of 100 days, each kg contained 7-8 catfish. Thus maggot can increase the weight of catfish significantly.In addition, maggot can reduce pellet consumption by up to 75 percent, so it can help catfish farmers in saving feed costs.Saat ini sampah merupakan masalah lingkungan yang sangat serius bagi masyarakat Kampung Baru, Desa Sampora, Tangerang. Pertambahan jumlah penduduk mengakibatkan pertambahan jumlah sampah. Menurut data produksi sampah di Tangerang pada tahun 2020 mencapai 22.873 ton, sedangkan sampah yang tertangani hanya sekitar 937 ton (4%). Permasalahan ini perlu segera dicari solusinya. Sampah  yang dihasilkan oleh rumah tangga dapat berupa sampah organik maupun anorganik. Jika sampah tidak dikelola dengan baik, maka sampah dapat merusak lingkungan sekitar. Sampah organik sering dianggap aman karena mudah terurai, padahal  sampah organik memiliki potensi untuk merusak lingkungan.Metode yang digunakan untuk memecahkan permasalahan sampah organik dapat dilakukan melalui biokonversi sampah organik menjadi maggot. Metode ini mempunyai kelebihan, karena selama proses biokonversi tidak menimbulkan bauyang tidak sedap. Biokonversi sampah organik dapat menjadi  solusi pengolahan sampah yang dapat  ditawarkan kepada penduduk Kampung Baru, Setiap 1 kg maggot membutuhkan 2 kg sampah organik/jam sebagai makanannya. Kecepatan maggot menggunakan sampah organik sebagai pakan, dapat menjadi alternatif untuk mereduksi jumlah sampah organik.  Maggot yang siap dipanen mempunyai kandungan protein yang sangat tinggi, sehingga dapat digunakan sebagai pakan lele atau ternak unggas lainnya. Lele  yang diberi maggot sebagai pakan, pada usia 100 hari, setiap kilogram berisi 6 ekor lele, sedangkan lele yang hanya diberi pakan pelet, pada usia 100 hari,setiap kg berisi 7-8 ekor lele. Dengan demikian maggot dapat meningkatkan berat lele secara signifikan. Selain itu maggot dapat mengurangi konsumsi pelet sampai 75 persen, sehingga dapat membantu peternak lele dalam menghemat biaya pakan.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from July to December 2004 to evaluate the effect of hill spacing on the performance of BRRI dhan40 and BRRI dhan41 as Transplant aman crop. The experiment consisted of five hill spacings viz., 5cm. 10cm, 15 cm, and 25 cm where row to row spacing of 25 cm was kept constant for all treatments. The experiment was laid out in randomized complete block design with four replications. The 25 cm x 5 cm hill spacing produced the tallest plant, highest total number of tillers/hill, bearing tillers/hill lowest number of non-hearing tillers/hill, grain yield and harvest index, while 25 cm x 5 cm hill spacing produced the highest number of sterile spikelets/panicle, straw yield and biological yield. BRRI dhan41 produced higher grain yield (4.7 t/ha) which was the contribution of higher number of grains/panicle and heavier grain weight. Lower yield (4.51 t/ha) was recorded in BRRI dhan40.Key Words: Varietal performance; T. aman rice; hill density.DOI: 10.3329/bjar.v34i1.5750Bangladesh J. Agril. Res. 34(1) : 33-39, March 2009

ABSTRACTThe composition and degradability of four varieties of rice straw were examined. The varieties were tall or short and early or late maturing. The straws and their botanical parts (leaf blade plus leaf sheath, internode, node and chaff) varied in acid-detergent fibre, ash and silica contents, but not in nitrogen and neutral-detergent fibre. There were some trends but no significant difference in proportions of parts between varieties. Milled samples of whole straw and its parts were either untreated, treated with a cellulase preparation plus propionic acid, treated with ammonia, or treated with cellulase then ammonia. Rumen degradability was measured by incubating the samples in polyester bags suspended in the rumen of sheep. The soluble fraction and potential degradability were greater in untreated short and early than in tall and late varieties, but rates of degradation did not vary significantly. Internode was more degradable than leaf. Cellulase and/or ammonia treatments increased the soluble fraction, especially in tall and late varieties, and increased potential degradabiiity except in internode. Degradability correlated positively with ash and silica contents.
