Abstract. Purba JH, Wahyuni PS, Zulkarnaen, Sasmita N, Yuniti IGD, Pandawani NP. 2020. Growth and yield response of shallot (Allium ascalonicum L. var. Tuktuk) from different source materials applied with liquid biofertilizers. Biodiversitas 21: 127-133. This research was to examine growth and yield of shallots using different sources of propagation material, namely true shallot seed (TSS) and bulbs. Soil biological fertility, which was generally low, was improved by the addition of liquid organic fertilizer. The purpose of this study a) to determine the differences in the propagation of plants from seeds and bulbs of shallot Tuktuk varieties, and b) to determine the effect of liquid biofertilizer maxigrow and rhizobacteria. The study used a one-factor randomized design. The results showed that the growth and yield of shallots propagated with bulbs were better than the origin of the seeds. The treatment of the two types of liquid biofertilizer produces tangible growth and yield, but there was no significant difference between the two kinds of liquid organic fertilizer.

An experiment was conducted at the Sher-e-Bangla Agricultural University farm from April to June 2017 in Kharif season to evaluate the performance of two mungbean varieties under different NPK fertilizers doses in field conditions. The experiment was laid out in Randomized Complete Block Design (RCBD), comprising six treatments with three replications. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the combination of the treatment were T0 = (control), T1 (10-40-25 NPK kg ha-1), T2 (10-60-45 NPK kg ha-1), T3 (20-50-35 NPK kg ha-1), T4 (30-40-25 NPK kg ha-1) and T5 (30-40-45 NPK kg ha-1), respectively. Mungbean cultivars responded noticeably to the supplementary NPK fertilizers as the crop characters were significantly influenced by different levels of NPK fertilizers. Data were recorded on plant height, leaves plant-1, branches plant-1, pods plant-1, seeds pod-1, 1000-seed weight, seed, and straw yield at different days after sowing. Of the two varieties, BARI mung-6 gave the highest seed yield (1.72 t ha-1) next to the higher plant growth and straw yield On the contrary, BARI mung-5 cultivar produced the lowest seed yield (1.57t ha-1), plant growth, and straw yield. The results showed that T3 (20-50-35 NPK kg ha-1) treatment was the best treatment as regards plant growth and yield parameters. The highest seed yield was produced by treated plot T3 (20-50-35 NPK kg ha-1) over the untreated control plot, T1, T2, T4, and T5, respectively. As for the combined effect, V1T3 (BARI mung-6 and T3 = 20kg N + 50kg P + 35kg K ha-1) performed the best results in all growth and development characters. Therefore, the combined application of 20-50-35 kg NPK ha-1 might be considered to be found optimal to get a considerable seed yield of mungbean variety BARI mung-6.

Transient waterlogging during winter and spring reduces wheat yield in many parts of southern Australia. Yield reductions from waterlogging are associated with reduced production and survival of tillers, fewer and smaller fertile tillers, and smaller grain size. Under favourable conditions, wheats that have the tiller-inhibition ('tin') gene produce a lower total number of tillers but a higher proportion of large, productive tillers and larger grains than wheats without this gene. These characteristics of restricted-tillering wheat may contribute to improved yield under transient waterlogging. We compared the growth and yield of the commercial variety Bodallin and 2 Bodallin backcross derivatives containing the 'tin' gene in 8 field trials grown on shallow, duplex soils in 1995 and 1996 at 3 locations in the south-west of Western Australia. Trials were sown at standard (1995) and standard and high (1996) seeding rates. Trial-mean yield ranged from 0.5 to 4.7 t/ha, depending on the occurrence and severity of waterlogging before anthesis and of soil water deficit before and after anthesis. Grain yield of the restricted-tillering (RT) lines averaged only c. 80% of Bodallin. At all sites and seeding rates the RT lines had fewer spikes per m2 (45% fewer, on average) but averaged 44% more grains per spike. In 1996 only, grain weight of the RT lines was 6% greater than of Bodallin. There was no evidence that the relative yield of the RT lines was greater at waterlogged sites than at other sites. Waterlogging reduced the number of fertile spikes of RT lines and of Bodallin to the same relative extent and differences in grains per spike and grain size had little effect on relative yields. Even though harvest index of the RT lines was slightly elevated in some environments, biomass production of the RT lines was low in all environments. We conclude that wheats with the 'tin' gene are unlikely to have a yield advantage under transient waterlogging unless their biomass production can match that of more freely tillering wheats.

Dicamba and 2,4-D are among the most common and inexpensive herbicides used to control broadleaf weeds. However, different studies have pointed the risk of crop injury and grain sorghum yield reduction with postemergence applications of 2,4-D. No research data on grain sorghum response to 2,4-D or dicamba exists in the Southeastern United States. Consequently, a study was conducted to investigate crop growth and yield response to 2,4-D (100, 220, and 330 g acid equivalent ha−1) and dicamba (280 g acid equivalent ha−1) applied on 20 to 65 cm tall sorghum. Greater stunting resulted from 2,4-D applied at 330 g acid equivalent ha−1or below 45 cm tall sorghum whereas lodging prevailed with 2,4-D at 330 g acid equivalent ha−1and dicamba applied beyond 35 cm tall crop. Regardless of local environmental conditions, 2,4-D applied up to 35 cm tall did not negatively impact grain yield. There was a trend for yields to be somewhat lower when 2,4-D was applied on 45 or 55 cm tall sorghum whereas application on 65 cm tall sorghum systematically decreased yields. More caution should be taken with dicamba since yield reduction has been reported as early as applications made on 35 cm tall sorghum for a potentially dicamba sensitive cultivar.

The experiment was conducted to determine the growth and yield response of pak choi (Brasiccarapa var. Chinkang Genghis Khan) to different foliar fertilizers (viz. vermitea, commercial foliar fertilizer, effective microorganisms [EM-1] and natural farming inputs [NFI]) under protected cultivation. It aimed to evaluate the influence of the different foliar fertilizers on pak choi in terms of growth characteristics, yield components, and pests and disease incidence. Similarly, to conclude which among the foliar fertilizers evaluated will be most the economical for pak choi production. The study was done in the DA-ATI IV-A and LSPU Organic Agriculture Learning Site in the Laguna State Polytechnic University, Siniloan, Laguna in December 2015 to February 2016. A total of 300 plants were used as experimental units in the study. Every treatment was replicated three times and each replication has 10 polyethylene bags planted with two plants each. Data was collected and analysed with the use of the Duncans Multiple Range Test (DMRT). Results revealed that the foliar fertilizers used have no remarkable effect on the weekly height, weekly growth rate, length of leaves, and shoot root ratio of pak choi. Nevertheless, commercial fertilizer significantly increased the mean number of leaves (7.53cm), width of leaves (15.10cm), economic and biological yields (105.10 grams and 106.88 grams, respectively) of pak choi compared with the rest of the treatments, except for vermitea which produced a comparable width of leaves (15.04cm). Also, a significantly lower number of the damaged leaves caused by looper (TrichoplusianiHübner) was noted on plants treated with commercial foliar fertilizer (0.51 leaf per plant). The highest net income was obtained by commercial foliar fertilizer-treated plants, but plants treated with vermitea earned the highest return of investment (ROI). Therefore, the utilization of vermitea in pak choi production can reduce the cost of fertilizer and contribute to an economical production system under protected cultivation.
