Germination And Growth

Hardwickia binata comes under the endemic biodiversity category and it is multipurpose tree species useful for agroforestry and dry land areas with medicinal, fodder, fuel, fibre, timber and manure utility / potential. It is essential to know more about its seed germination and growth. In present studies the attempts have been made to investigate seed germination and growth performance at three different places located in three different districts. The seed germination and growth performance experiments were carried out for one year on different treatments in nursery, laboratory and field for parameters viz. seed germination, seedling growth and survival rate in H. binata. The investigations revealed that seed germination and growth performance considerably varies with soil combination and locality or region. This study results may be useful in nursery and forestry management as well as conservation of H. binata.

Laju pertumbuhan dan tingkat reproduksi yang tinggi merupakan karakteristik unggul yang dimiliki ikan nila sebagai komoditi budidaya. Tingkat reproduksi yang tinggi menyebabkan terjadinya pematangan gonad sebelum mencapai ukuran produksi dimana hal tersebut dapat merugikan pembudidaya, karena saat ikan mengalami matang gonad energi hasil asimilasi pakan sebagain besar akan dialokasikan untuk perkembangan gonad dan menghambat pertumbuhan somatik. Pemanfaatan senyawa aktif dari bahan alami biji pepaya dapat menjadi solusi untuk meningkatkan pertumbuhan ikan yang dibudidayakan sekaligus menjaga keamanan pangan dan konsumen. Penelitian ini bertujuan untuk mengetahui pemanfaatan tepung biji pepaya terhadap respons pertumbuhan dan tingkat kelangsungan hidup ikan nila. Ikan nila diberi perlakuan dengan lima dosis tepung biji pepaya berbeda (0, 1, 3, 5 dan 7 g/kg pakan) secara oral berdasarkan feeding rate 5% dengan tiga ulangan selama 30 hari pemeliharaan. Hasil penelitian menunjukkan dosis 5 g/kg meningkatkan pertumbuhan bobot tubuh tertinggi sebesar 547 g dibandingkan kontrol sebesar 406 g. Sejalan dengan pertumbuhan bobot tubuh, dosis 5 g/kg menghasilkan tingkat kelangsungan hidup ikan nila sebesar 100% dibandingkan kontrol sebesar 66%. Dari hasil yang diperoleh dapat disimpulkan bahwa tepung biji pepaya dengan dosis 5 g/kg pakan dapat meningkatkan pertumbuhan dan tingkat kelangsungan hidup ikan nila selama 30 hariHigh growth rate and high reproductive cycle are some economical triats on nile tilapia. This is a setback for nile tilapia culture because when the fish reach gonad maturity before reach market size, all the energy demand will flow to reproduction and can cause stunt growth. The utilization of natural compound from papaya seeds can be a solution to enhance growth of farmed nile tilapia and for consumer and food safety. This research aim to know how papaya seed powder can enhance growth and survival rate of nile tilapia. This research conducted into five groups of 5 papaya seeds powder dosage (0, 1, 3, 5 and 7 g/kg) that feed orally to the treatment fishes. Result showed the fishes feed with 5 g/kg papaya seed experienced highest growth performance 547 g compare to control which is 406 g. Same as growth performance, survival rate shown that group feed with 5 g/kg papaya seed had 100% survival rate compare with control which is 66% during treatment periods. Base on this result, we can make conclusion that fish feed with 5 g/kg of papaya seed have a better growth performance and survival rate compare with control group for 30 days treatment periods

The efficacy and suitability of dietary whole wheat flour supplementation was evaluated on the growth performance and survival of rohu (Labeo rohita). The study was conducted in 12 experimental aquaria at the Wet Laboratory, Department of Aquaculture, Bangladesh Agricultural University, Mymensingh. A total of 180 fingerlings of mean initial weight of 1.744±00 g were stocked at the same stocking density (268 fingerlings/m3). Four different treatments (T1, T2, T3 and T4) each with three replications were performed having different level of whole wheat flour such as 0% whole wheat flour (T1), 5% whole wheat flour (T2), 10% whole wheat flour (T3) and 15% whole wheat flour (T4). Feeds were supplied at 5% body weight twice daily in the morning at 9.00 am and in the afternoon at 5.00 pm throughout the study period. The rations were adjusted every week when new weights of the fish for various experimental aquariums were determined. At the end of the 63 days study period, the growth performance parameters such as mean final weight (g), weight gain (g), percent weight gain (%), specific growth rate (%/day) and the best feed utilization in terms of food conversion ratio were found highest at treatment 4 where fishes were fed with inclusion of 15% whole wheat flour and lowest was found at treatment 1 (fed with inclusion of 0% whole wheat flour). Water quality parameters were within the acceptable range and survival rate was found 100% in all treatment. Therefore, it can be concluded that treatment 4 (highest growth performance and survival rate of L. rohita with supplementation of 15% whole wheat flour containing diet) can be chosen by fish farmers for commercial culture of this species.

Study Results

The larvae of white leg shrimp (Litopenaeus vannamei Boone, 1931) at phase nauplii 6 fed with a stocking density of 150 pcs per litre and 3 formula including formula 1 with dry microalgae Spirulina + artemia as main ingredients, formula 2 with microalgae Thalasiosira weissflogii + artemia as main ingredients and formula 3 with microalgae Thalasiosira pseudonana + artemia as main ingredients. Experiments were carried out in 18 tanks fifty-litre composite at Quang Binh branch of C.P Vietnam Corporation. The study results show that, with formula 3, white leg shrimps larvae at zoea stage have the highest growth and survival rates (86.57 %), followed by formula 2 (76.03 %) and finally formula 1 (67.90 %). White leg shrimps larvae at zoea stage in formula 3 have the shortest metamorphosis time (78.61 hours), followed by formula 2 (83.25 hours) and the longest in formula 1 (94.10 hours).

An experiment to observe the growth performance of the larvae produced from female Clarias batrachus treated with 4 dietary levels of vitamin E viz. 0 mg, 50 mg, 100 mg, and 200 mg /kg feed was conducted for 28 days. After rearing for 3 months females were used for induction of breeding to produce larvae. Same dose of pituitary gland (100 mg PG/kg body weight) was used for all treatments. From the 7th day of hatching, the larvae were reared for another period of 28 days to see growth and survival rate of the larvae produced by the broods maintained under different dietary levels of vitamin E. In case of growth performance (percent length gain, percent weight gain, specific growth rate) and health condition larvae of T2 (50 mg vitamin E/kg feed) showed significantly better result when compared with those of T1 and T3. There was no significant difference in the growth performance between the larvae of T2 and T4. Larvae of T2 although showed higher survival rate but the difference between different treatments was insignificant. The results concluded that 50 mg vitamin E/kg feed is more suitable to increase growth and survival rate of the larvae.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16862 Progress.

Germination And Growth

Field and container studies were conducted to determine effects of prodiamine on Florida betony and leatherleaf fern. Effects of Florida betony competition on leatherleaf fern frond yield and quality were also determined. Seed germination and growth and flowering of established Florida betony decreased with increasing prodiamine application rates; 4.5 kg ai ha-1or higher prevented seed germination and eliminated or nearly eradicated established betony one year after treatment. Prodiamine treatments up to 6.7 kg ai ha-1did not affect leatherleaf fern growth, frond yield (number, fresh weight) or quality (color, size, vase life). When leatherleaf fern and Florida betony were grown together in containers for 7 mo, fern frond yield and quality were reduced.
