Sulphur is a component of plant amino acids, proteins, vitamins, and enzyme structures which influence the productivity of oil seed and total oil content. The experiment was conducted to find out the effect of sulphur on the seed yield and oil content of sesame in Bangladesh. The experiment comprised three varieties of sesame viz. Binatil-2, Binatil-3 and BARI Til-4 and six levels of sulphur (S) viz. 0, 10, 20, 30, 40 and 50 kg S ha–1. The experiment was laid out in a randomized complete block design with three replications. Dry matter production, crop characters, yield components, seed yield and oil content were significantly influenced by variety, level of sulphur and their interaction. The highest dry matter production plant–1 at 50 DAS (17.56 g), plant height (101.3 cm), number of branches plant–1 (3.66),  number of pods plant-1 (41.56), number of seeds pod-1 (58.83),  seed yield    (747.2 kg ha-1), stover yield (2243.0 kg ha–1) and oil content (40.03%) were obtained in BARI Til-4 while the corresponding lowest values of all parameters were recorded in Binatil-2. In case of sulphur application, the highest dry matter production plant–1 at 50 DAS (20.81 g), plant height (109.7 cm), number of branches plant–1 (3.87),  number of pods plant–1 (46.13),  number of seeds pod-1 (56.67),  seed yield (800.0 kg ha–1), stover yield (2787 kg ha–1 ) and oil content (43.97%) were obtained when crop was fertilized with 30 kg S ha–1 while the lowest seed yield (502.2 kg ha–1), stover yield (1550.0 kg ha–1) and oil content (32.80%) were obtained in control (0 kg S ha–1). BARI Til-4 fertilized with 30 kg S ha–1 produced the highest dry matter plant–1 at 50 DAS (24.80 g), number of pods plant–1 (51.13), seeds pod–1 (62.0) and seed yield (1011.0 kg ha–1). The highest oil content (43.97%) was also recorded in BARI Til-4 fertilized with 30 kg S ha–1, which was as good as that of BARI Til-4 fertilized with 40 kg S ha–1. Therefore, BARI Til-4 fertilized with 30 kg S ha–1 can be considered as a promising practice in respect of seed yield and oil content of sesame in Bangladesh. J. Bangladesh Agril.

Community farms mostly only use the main products of the farm alone, did not see many more opportunities of byproducts such as feces and urine of livestock. Byproducts can be used for very useful organic fertilizers from crops especially forage for animal feed such as mini elephant grass (Pennisetum purpureum schamach) which is able to grow in various types of soil and is a grass of high nutritional value of fiber favored by livestock. The purpose of this study was to examine the effects from the provision of feces and urine buffalo mud and cutting intervals on the production and nutritional content of Pennisetum purpureum schamach. This research has been conducted at the Faculty of Agriculture, University of Sumatra Utara from July to October 2015. This study used Split Plot Design, consisting of cutting interval (4 weeks and 6 weeks) as main plot and type of fertilizer (control / no fertilizer application, mud buffalo feces, buffalo feces + non fermented urine buffalo and feces from buffalo mud + urine fermentation) as subplot. The observed variables were plant height, fresh production, dried production, number of tillers, crude protein and crude fiber from Pennisetum purpureum schamach forage. Cutting intervals have a significant effect on improving nutritional content such as crude protein and crude fiber of mini elephant grass. The interaction of the results showed that the provision of impurities from mud buffalo (feces and urine) gave a real effect to increase fresh production, dry matter production, plant height and number of mini elephant grass. The interaction of the results showed that the provision of impurities from mud buffalo (feces and urine) gave a real effect to increase fresh production, dry matter production, plant height and number of tillers mini elephant grass.. Provision of mud buffalo dung (feces and urine) showed a real interaction with fresh production, dry matter production, plant height, number of tillers, crude protein and crude fiber.Keywords:Pennisetum purpureum Schamach, feces, urine, and and forage productivity

Water Depths

This study aimed to evaluate how different irrigation water depths influence the agronomical features of elephant grass (Pennisetum purpureum Schum) cv. Roxo. Grass was cultivated in a pasture belonging to the Bovine Sector of the National Agrotechnical School of Caceres – MT. The experiment was a block design with five treatments and four repetitions. Treatments consisted of five water depths: 0 = 0% of available water (AW), 1 = 21% of AW, 2 = 34% of AW, 3 = 74% of AW, and 5 = 100% of AW. Evaluated features were production (dry matter ha-1), plant height, leaf/steam ratio, and stem diameter. Dry matter production of cuts from May and July increased linearly with increasing water depth (P < 0.05). Plant height increased linearly as water depth increased in the cuts of May and September, while the height of July cuts was 71.76 cm under an irrigation depth of 390.77 mm. In May, July, and September cuts, leaf percentage decreased linearly as water depth increased (P < 0.05). An increase of 1 mm in water depth reduced leaf percentage by 0.0936% (May), 0.0295% (July), and 0.0122% (September). Our results indicate that to improve dry matter production, May, July, and September cuts should be irrigated with water depths of 56.03 mm, 601.78 mm, and 577.65 mm, respectively.

Alfalfa dry matter production, plant height, protein content, and in vitro digestibility (IVD) were measured in first- and second-year plantings of six alfalfa cultivars grown under natural potato leafhopper infestation with and without methoxychlor treatment for control of the pests. All treated plots yielded more dry matter than the untreated check, except Angus in 1978. Plant height and protein content were higher and IVD was less in the treated plots. All cultivars were susceptible to leafhopper infestation; however, Angus was the least affected. Leafhopper injury was season-specific and damage carry-over from one season to another occurred but was less than from one cut to the next.
