The yield and quality of perennial ryegrass, short-rotation ryegrass–perennial ryegrass mix, oats, millet, maize, rape, kale, pasja and turnips were determined over a 13-week summer period in 1995–96 and 1996–97. The experiment was conducted on the Elliott Research Station in north-western Tasmania (145˚E, 41˚S) and consisted of 2 irrigated and 2 dryland main plots. Within each main plot was a randomised complete block design with 9 forage crop subplots. Where forage is required through the summer, there is little advantage in establishing millet or oats over a spring-sown ryegrass pasture, mainly as the former still require replacement with permanent pasture in the autumn. However, if additional forage is required from late January then turnips are clearly superior to the other forages evaluated in all respects, apart from a low bulb crude protein (CP) content. Turnips responded significantly to irrigation, producing between 15 and 22 kg DM/ha.mm irrigation applied, with yields ranging between 7.9 and 10.6 t DM/ha dryland and between 13.5 and 14.4 t DM/ha under irrigation. The metabolisable energy (ME) and CP contents of turnips were 12.5 MJ/kg DM and 12.4% in the shoots and 13.4 MJ/kg DM and 7.0% in the bulbs, respectively. In comparison, the other fodder crops tested yielded between 4 and 6 t DM/ha under dryland conditions and between 5 and 7 t DM/ha under irrigated conditions. Turnips were most economic, costing on average A$120/t DM irrigated and $160/t DM dryland, while spring renovation to perennial ryegrass cost $385/t DM irrigated and $344/t DM dryland; clearly more expensive than purchased feeds for this period. These findings confirm the choice of many farmers that, of the species examined, turnips are the most suitable as a summer fodder crop, both irrigated or dryland, and integrate well with a pasture renovation rotation.

Field experiments were conducted to study the effect of establishment techniques on yield and economics of red gram [Cajanus cajan (L.)] under irrigated condition at Regional Research Station, Tamil Nadu Agricultural University, Paiyur - 635 112,Tamil Nadu, India during Kharif season of 2013-14 and 2014-15 respectively in randomized block design with four replications. The treatments are line sowing/dibbling of seeds, sowing behind the country plough, sowing in polybag and transplanting at 25 and 40 DAS, sowing in portrays and transplanting in 25 and 40 DAS. The redgram variety LRG 41 was used for study. The results revealed that, dibbling of seeds in lines recorded higher grain yield of 2351 kg ha-1, net income of Rs.99495/- and B:C ratio of 3.39. Thus, dibbling of seeds in lines recorded 6% higher over sowing in poly bag and transplanting at 25 DAS and 27% higher yield over sowing behind the country plough. Considering yield and economics, line sowing seems to better option for the farmers followed by sowing in polybags and transplanted in 25 DAS. Under transplanted situation, transplanting of seedlings at 30 DAS was more suitable where the monsoon was delayed for 30 to 45 days under rainfed situation.

One of the diseases that often found in sorghum plants is anthracnose disease caused by Colletotrichum sp. The purposed of this study was to determine the effect of adding micro fertilizer and the use of several sorghum genotypes on the intensity of anthracnose disease. The study was conducted in Sukanegara, Tanjung Bintang, South Lampung in April 2017 - February 2018 and at the Laboratory of Plant Diseases and Pests, Faculty of Agriculture, University of Lampung. The treatments were arranged using a randomized block design in a split plot design (3 times replications), the main plot was micro nutrients (with micro addition and without micro addition) and 15 subgroups of sorghum genotypes (Numbu, Samurai 1, GH3, UPCA, GH4, P / I WHP, GH6, Super 2, GH13, P / F 51-93-C, Super 1, GH5, Mandau, GH7, and Talaga Bodas). The results showed that the addition of "ZincMicro" micro fertilizers to sorghum plants did not affect the intensity of anthracnose disease, however there were differences in the intensity of anthracnose diseases between sorghum genotypes. Numbu Genotype, GH 3, and GH 13 were relatively more resistant to anthracnose disease than the other genotypes.

SummarySheep prepared either with a rumen cannula, or with a rumen cannula plus re-entrant cannulae in the duodenum and ileum were fed fresh ‘Ruanui’ perennial ryegrass (R), ‘Manawa’ short rotation ryegrass (M) and white clover (C) at dry-matter intakes ranging from 450 to 1000 g/24 h. Paper impregnated with chromic oxide was given once daily via the rumen fistula as a marker.Amounts of non-ammonia-nitrogen (NAN) entering and leaving the small intestine and nitrogen (N) excreted in the faeces were regressed against the intake of N for each sheep and these equations (all significant P < 0·05) were used to calculate the extent of digestion in the stomach, the small intestine and the large intestine at two levels of OM intake (500 and 800 g daily). Amino acid analyses of feed and digesta samples are also presented together with calculations of the apparent absorptions of individual amino acids from the small intestine.At an intake of 500 g OM amounts of NAN entering the small intestine were significantly greater (P < 0·05) in sheep given M than in sheep given R or C. At an intake of 800 g OM amounts in sheep given M were significantly greater (P < 0·01) than in sheep given R. NAN leaving the small intestine and N excreted in the faeces were similar for all three diets.At an intake of 800 g OM apparent absorptions of NAN from the small intestine of sheep given M (0·47 × N intake + 2·8 g/24 h) and sheep given C (0·51 × N intake – 1·3 g/24 h) were significantly greater (P < 0·01 and P < 0·05 respectively) than of sheep given R (0·41 × N intake – 0·5 g/24 h). As intake of herbage was increased the partition of digestion altered.Only small differences between herbages were found in the amino acid composition (g amino acid/100 g protein) of either duodenal or ileal digesta, but because of the large differences in the flows of NAN, the apparent absorptions of individual amino acids from the small intestine were much higher in sheep given M than in sheep given the other two species.The results are discussed in the light of available information on sites of digestion of herbage diets in sheep.

<p><strong>The effect of living post and pepper vines primings on the pepper yield</strong></p><p>To obtain good yield of pepper, farmers fequently apply various treatments to their crops, including pruning of the pepper vines and or their living post. Studies on the aspects of the pruning ae however very limited. Therefore a ield experiment was conducted to investigate the effects of pruning of pepper vines and their living post on the pepper yield. The experiment was carried out at Sukamulya Research Station, Sukabumi. A split plot design with three rcplicaties was used. The main plot was the pruning of living post, and the sub plot was the pruning of pepper vines Plot size was 20 plants per plol wilh spacing of 2.5 m x 2.5 m Results showed that there was signiicant interaction between the pruning of living post and pepper vines. The pruning of living post may be carried out either 3 times (October, January and April) or twice (October and January) a year. However. If the pruning of the living post is carried out 3 times per year, Ihe vine would be pruned once a year or not at all. On the other hand, if the pruning of living post is carried out twice a year, the pepper vines would be pruned 6 times a year.</p>

Biological Actions

Our study compares the content in polyphenolic compounds and hypericin, in four species of Hypericum - H. perforatum L., H. maculatum Cr., H. hirsutum L., H. tetrapterum Fr. (syn. Hypericumacutum Mnch.) harvested from spontaneous flora in the north-western area of Transylvania, Romania. These species represent an important source of such compounds with different biological actions. After making the extracts, they were subjected to HPLC-SM analysis. The presence of rutoside in the largest amount (462.82 mg %) in the H. perforatum extract was observed, this containing most of the flavonoid heterosides. For the species H. maculatum, the presence in a much higher amount of the hyperoside (976.36 mg %) is characteristic compared to the other species. Quercetol is the best represented of the flavonoid aglycons, its concentration being the highest in H. hirsutum (659.66 mg %). The hypericin content ranges from 0.2171 g % in the H. tetrapterum extract, to 0.0314 g % in the methanol extract of H. maculatum.The highest antioxidant properties measured by FRAP method were recorded in the case of H. perforatum and H. maculatum.

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.

A field experiment was carried out during 2015-16 and 2016-17 at ICAR-Central Potato Research Station, Patna, Bihar, in randomized block design with four replications with objective to quantity the optimum requirement of nitrogen to potato crop. Significantly the highest plant height was recorded with nitrogen level of 300 kg/ha. Distributions of the smallest size of tuber yield of potato were decreasing with increasing the level of nitrogen. There was about 26.0% more yield of the smallest size tuber of potato was recorded with zero nitrogen as compare to the highest level of nitrogen i.e. 300 kg/ha. Increasing the nitrogen over the level of 150 to 225 kg per hectare, increasing the yield of tuber gradually slower rate than nitrogen level from 0 to 150 kg/ha. Total and marketable tuber yield of potato were increasing significantly with increasing level of nitrogen up to 150 kg/ha. There was no significant difference in marketable tuber yield was found for nitrogen level between 150 and 225 kg/ha. Highest (1.66) net benefit cost ratio was also recorded with level of nitrogen @ 150 kg/ha in potato. Hence, application of nitrogen @ 150 kg/ha was found statistically and economically more beneficial for potato cultivation in Eastern Indo-Gangatic plain of India.
