Bud Chip Method: A Potential In vitro Technology for Bajra-napier Hybrid (Pennisetum glaucum L. X P. purpureum Schum.) for Sett Multiplication

Background: Forages of high quality are the most valuable commodity of any livestock activity and they serve as the basis for most of the rations in a forage-based diet. The lack of good quality seedlings/seeds, notably improved varieties, is the primary reason for the slow adoption of improved forage production technologies. Traditional establishment of bajra napier forage incurs more labour costs, harvesting sett material, transporting, preparing two budded setts and carrying to the planting area. Nearly three to four tons of green leaves stem materials are wasted for planting one hectare of area. In this situation, an alternate method is required to produce high-quality seedlings in a short period. This research objective compared single node bud chip seedling in different protray cell cavities and pot mixtures. Methods: The green shade net field study was carried out between 2019 and 2020, the effect of different pro-tray sizes (50, 60 and 98 cell cavities) and potting mixture (red earth, cocopeat, farmyard manure, vermicompost and root growth promoters like phosphobacteria bio-fertilizer and indole acetic acid (IAA) was taken in different combination for the establishment of Bajra Napier hybrid variety Co (BN)-5 seedling by using single node bud chip technology. The observation was taken up to 30 days in related to seedling growth and development. The observed parameter was statistically analysed in SPSS software. Result: Among the three different protray cavities and five different pot mixtures, 60 cavity protray with red earth + cocopeat + vermicompost (2:1:1) results revealed significant differences (p greater than 0.05) in seedling growth parameters among the different protray and growing media. The maximum seedling growth parameters like germination, numbers of the leaf, plant height, leaf length, width and root length (94.4 per cent, 8.17, 39.12 cm, 38.14 cm, 2.5 cm and 30.8 cm) were observed at 30 days aged seedlings followed by red earth + cocopeat + farmyard manure (2:1:1 ratio) and treated with IAA substance in 60 cavity protray.

Effect of Plant Density and Nitrogen Management for Realizing Higher Cane Yield under Bud Chip Method of Planting in Sugarcane (Saccharum officinarum)

A field experiment was conducted at Regional Sugarcane and Rice Research Station, Rudrur, during 2018-19 to study the effect of plant density and nitrogen management for realizing higher cane yield under bud chip method of planting in sugarcane (Saccharum officinerum). The treatments were plant geometry and nitrogen doses with three and four splits of application in split plot design. The recommended dose of nitrogen was 250 kg N ha-1. Among the geometry, 150 x 60 cm spacing recorded significantly higher cane length which was statistically at par with 150 x 30 cm. 150% RDN (375 kg N ha-1) with four splits of application recorded significantly higher cane length. Among the split application of nitrogen, four splits with 150% RDN at basal, 60, 90 and 120 DAP recorded significantly higher number of tiller at 90 and 120 DAP. Significantly higher single cane weight was recorded in 150% RDN with four splits of application in 150 x 60 cm. Significantly higher cane yield was recorded in 150% RDN with four splits of application in 150 x 60 cm spacing and was statistically at par with 150 x 30 cm spacing. This was followed by 100% RDN with four splits of application in 150 x 60 cm spacing.

Aplikasi IAA Terhadap Kecepatan Tumbuh Asal Bibit Bud Chip Tebu (Saccharum officinarum L.) di Persemaian Pottray

Penelitian ini dilaksanakan di Politeknik Negeri Lampung pada bulan Desember sampai Februari 2019. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) faktorial dengan 2 faktor. Faktor pertama adalah sumber bud chip yang berasal dari 3 bagian batang yaitu B1 (atas), B2 (tengah) dan B3 (bawah). Â Faktor kedua adalah konsentrasi ZPT IAA dengan 4 taraf yaitu A0 (0 mg ), A1 (150 mg ), A2 (300 mg ), A3 (450 mg ). Â Variabel yang diamati adalah kecepatan tumbuh mata tunas, persentase tumbuh tunas (%), tinggi tanaman (cm), jumlah daun (helai) dan diameter pelepah (mm). Hasil penelitian menunjukan asal bibit bud chip bagian tengah memiliki pertumbuhan terbaik terhadap variabel kecepatan tumbuh, persentase tumbuh, tinggi bibit, jumlah daun, dan diameter pelepah. Pemberian ZPT IAA pada konsentrasi 0-450 mg l-1Â yang telah diterapkan pada sumber bud chip bagian atas, tengah, dan bawah dengan perlakuan perendaman selama 20 menit tidak memberikan dampak yang nyata pada kecepatan tumbuh, persentase tumbuh, tinggi bibit, jumlah daun, diameter pelepah dan tidak terdapat interaksi antara perlakuan asal bibit bud chip (atas, tengah, bawah) dan konsentrasi ZPT IAA (0 mg l-1 ,150 mg l-1Â ,300 mg l-1 dan 450 mg l-1 ).

Perkecambahan dan Pertumbuhan Awal Budset dan Budchip Tebu (Saccharum officinarum L.) yang Ditanam pada Berbagai Posisi Mata Tunas

Germination phase is a crucial stage in the cultivation of sugarcane. This phase is influenced by numerous factors, such as the position of bud when the sugarcane seed is planted. This study aims to examine the responses of germination and early growth of sugarcane bud chip and budset seeds variety PS 862 that are grown in various bud positions, namely upward, downward, and side positions. Results explicated that there were significant differences in the seed germination that are grown with various bud positions. Seeds that are planted with a downward bud position germinate slower than the two other bud positions. However, the percentage of germination of all treatments were classified as vigorous since the numbers are more than 80%. There was a strong influence of the bud position on the number of tillers and root/shoot ratio. Seeds that are planted with upward and side bud position have more tillers than seeds grown with the two other positions. The root/shoot ratio was higher in seeds grown with upward positions than the other positions. Meanwhile, there were no significant effects of bud positions and the form of seed on plant and stem height, the number of leaves, as well as root, shoot, and total dry weight of the crop.

Pengaruh Komposisi Pupuk Organik Terhadap Pertumbuhan Bibit Budchip Tanaman Tebu (Saccharum officinarum L.)

Breeding of bud chip cane is an application of ratoon unloading program which often get difficulty fulfilling the requirement of certified seed. Efforts to increase production and restoration of soil fertility can be done application of organic fertilizer compost humic acid, kiambang, and manure. The study aims to get the best bud bud chips. Getting the most effective dose of organic fertilizer composition. and get the interaction of seed bud bud part and organic fertilizer composition. The research method used Group Random Design. The first factor is 3 parts of seedlings (B1) bud seed bud chip (B2) bud seed bud chips the middle, (B3) bud seed bud chip, and second factor amount of composition of organic fertilizer (P) comparison Humic Acid: Kiambang: : (P0) 10%: 70%: 20% (P3) 20%: 10%: 70%, (P4) 30%: P0) without organic fertilizer (P1) 30%: 40%, (P5) 100% humic acid organic fertilizer, (P6) 100% kiambang compost, and (P7) 100% manure. the results of the observations were analyzed by the analysis of variance with the F test, in the Advanced Test with the BNT Test at the 5% level of confidence. The results showed bud buds chip B1 growth faster than B2 and B3. The provision of organic fertilizer P2 composition was significantly better to plant height, while the organic fertilizer composition of P7 showed an increase in leaf number and stem diameter better than other organic composition
