Since open-field agriculture will face some severe problems in the near future like availability of land and agricultural productivity, an alternative cultivation system, such as soilless cultivation is needed for the sustainability of supply and demand for healthier and safer food. This study aimed to test the effect of vermicompost application method and dosage on growth, yield, and chlorophyll content of water spinach. This experiment used a factorial randomized block design with controls. The first factor was the vermicompost application method, which consisted of three levels, namely solid vermicompost, the combination of solid and liquid vermicompost, liquid vermicompost. The second factor was the vermicompost dosage, which consisted of five levels: 100, 200, 300, 400, and 500g per polybag, compared with control using inorganic fertilizer. The results showed that the vermicompost application method did not significantly affect plant growth and yield. The dosage of 500g in the three different application methods gave significantly higher plant growth compared to control. The fresh weight of water spinach per plant and per polybag in the dosage of 500g showed the highest yield of 13.95g and 122.17g, respectively. The highest chlorophyll content of water spinach was found in solid vermicompost treatment with an application rate of 500g, namely 30.10 µg/ml (chlorophyll A) and 54.79 µg/ml (chlorophyll B). These results indicate that to produce high-quality water spinach in soilless culture systems, it is recommended to use solid vermicompost with an application rate of 500g per polybag.

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.

Economic use of organic and inorganic fertilizers following their availability is necessary for livestock-based Nepalese farming systems. However, how best to integrate these fertilizers in an appropriate manner is not yet clear. Thus, this study was conducted in the horticulture farm of the Agriculture and Forestry University (AFU), Rampur, Chitwan, Nepal from November 2018 to February 2019 to evaluate the effect of organic and inorganic sources of nitrogen (N) on growth, yield, and quality of beetroot (Beta vulgaris L.) varieties. The experiment was laid out in a two factorial randomized complete block design with four replications consisting of two beetroot varieties, i.e., Madhur and Ruby Red, and five N source combinations, i.e., N1: 100% poultry manure (PM), N2: 50% PM + 50% urea, N3: 100% farmyard manure (FYM), N4: 50% FYM + 50% urea, and N5: 100% urea (120:80:40 kg NPK ha−1). Results of this study indicated a significant impact of N sources and varieties on the assessed parameters. During harvest, a significantly higher plant height (41.84 cm), number of leaves per plant (14.68), leaf length (34.56 cm), leaf width (11.38 cm), and beetroot diameter (72.15 mm) were observed in the N2 treatment. Likewise, higher economic (49.78 t ha−1) and biological yields (78.69 t ha−1) were also recorded in the N2 compared to other N sources. Out of the two varieties, the Madhur variety was significantly better in most growth and yield parameters. Similarly, the Madhur variety showed a significantly higher economic (44.49 t ha−1) and biological yields (69.79 t ha−1) compared to the Ruby Red variety. However, the physiological weight loss was higher in the Ruby Red variety. Therefore, the current study suggests that an integration of poultry manure along with the combination of N fertilizer and the Madhur variety is the best combination for quality beetroot production in the Terai region of Nepal.

Green pepper (Capsicum annuum L.) is an important vegetable in the Kingdom of Eswatini. However, there is rare information on pepper production using cattle manure.  The experiment was conducted at the University of Swaziland, Luyengo Campus, in the Horticulture Department Lath-house to determine the effects of different rates of cattle manure on the growth and yield of green pepper in order to come up with a suitable application rate for green pepper. Cattle manure was applied at different rates of 20, 40, 60 and 80 tons/ha in a Randomized Complete Block Design, while 2:3:2 which was used as a control was applied at 150 kg/ha. For every increase in the application level/rate of the cattle manure, there was a considerable increase in the growth parameters that were measured. Results obtained from this experiment indicate that applying cattle manure at 80 tons/ha gave relatively higher yields. This cattle manure rate can be used by farmers in green pepper production.

Plant growth, yield, pigment and protein content of cow-pea were increased significantly at lower levels (20 and 40%) of fly ash but reverse was true at higher levels (80 and 100%). Soil amended by 60% fly ash could cause suppression in growth and yield in respect to 40% fly ash treated cow-pea plants but former was found at par with control (fly ash untreated plants). Maximum growth occurred in plants grown in soil amended with 40% fly ash. Nitrogen content of cow-pea was suppressed progressively in increasing levels of fly ash. Moreover,  Rhizobium leguminosarum  influenced the growth and yield positively but Meloidogyne javanica caused opposite effects particularly at 20 and 40% fly ash levels. The positive effects of R. leguminosarum were marked by M. javanica at initial levels. However, at 80 and 100% fly ash levels, the positive and negative effects of R. leguminosarum and/or M. javanica did not appear as insignificant difference persist among such treatments.Key words:  Meloidogyne javanica; Rhizobium leguminosarum; Fly ash; Growth; YieldDOI: 10.3126/eco.v17i0.4098Ecoprint An International Journal of Ecology Vol. 17, 2010 Page: 17-22 Uploaded date: 28 December, 2010
