Goats are an important component of the livelihoods of resource poor livestock keepers (RPLK) in Nepal. A major constraint is the poor health (and low economic value) of goats in the early part of the wet season, and this is partly brought about by the shortage of available forage in the dry season. Two invasive weeds (Eupatorium adenophorum, EA, and Chromolaena odorata, CO) now grow throughout Nepal. The plants grow year round, and so could be used as a source of forage, but their voluntary intake and perceived nutritive value by goats is low. If an appropriate means of treating EA and CO could be developed, their nutritive value may increase. EA and CO could then be included in the forage harvested for goats. The objective of this experiment was therefore to determine the effect on the nutritive value of EA and CO of either wilting or soaking these plants.

Allelopathic Potential

An extensive survey of floristic of native and invasive weed species was carried out during 2016 to 2019 in the semiarid agro ecosystem of Baramati Tahsil, Dist- Pune (M.S.). About 18 dominant invasive weeds such as Ageratum, Alternanthera, Croton., Xanthium, Parthenium and Tridax were encroaching the natives, becoming a serious threat to the major crops of this area such as wheat, sorghum, pearl millet, mung bean, pigeon pea, chillies and tomato. Amongst these Croton bonplandianus was highly dominant and wide spreading. Hence, its allelopathic potential was investigated. The allelopathic influence of leaf and root leachates as well as extracts of Croton bonplandianus Bail. was examined on seed germination of mung bean (Vigna radiata L.). The germination assay revealed that allelopathic potential and other factors are responsible for its dominance and successful invasion. The allelopathic influence of rhizosphere soil and its aqueous leachates indicated that both are responsible for inhibiting the seed germination and seedling growth of mungbean. Both the experiments have clearly confirmed the allelopathic potential of Croton bonplandianus. The HPTLC analyses confirmed the existence of a broad groups of allelochemicals like terpenoides, steroids, flavonoids, pungent and bitter essential oils and phenolics in its leaves and roots, which confirmed its allelopathic potential. Further characterization of above mentioned allelochemicals is in progress.

A total of 16 different allergenic and invasive weed species belonging to 12 different families collected from different areas of study area. Among the studied plants, most of the species belong to the Asteraceae family. For morphological studies of pollen through LM and SEM the samples were acetalized. We done the fieldwork for the collection of weed plants and also performed the experimental work i.e. SEM and LM for the pollen morphology. Most of the species recorded with pollen of tricolporate and echinate. Species belonging to Asteraceae were considered as most abundant and allergenic as compared to others. The maximum polar diameter was noted in the Convolvulus arvensis is 40.00 µm and the minimum were noted in Oxalis corniculata is 6.15 µm. Maximum exine thickness was noted in convolvulus arvensis is 3.70 µm and Minimum were noted in Sorghum halepense is 1.65 µm. It was noticed that most of the allergenic and invasive weeds found in plain areas of Lakki Marwat during September and April. Present study provides information about the allergenic and invasive weeds plants and their threats to biodiversity. The pollen of such weed plants causes asthma and atopy disease in humans.

Solanum rostratum Dunal is an invasive weed species that invaded Israel in the 1950s. The weed appears in several germination flashes, from early spring until late summer. Recently, an increase in its distribution range was observed, alongside the identification of new populations in the northern part of Israel. This study aimed to investigate the efficacy of herbicide application for the control of S. rostratum using two field populations originated from the Golan Heights and the Jezreel Valley. While minor differences in herbicide efficacy were recorded between populations, plant growth stage had a significant effect on herbicide response. Carfentrazone-ethyl was found to be highly effective in controlling plants at both early and late growth stages. Metribuzin, oxadiazon, oxyfluorfen and tembutrione showed reduced efficacy when applied at later growth stage (8–9 cm height), as compared to the application at an early growth stage (4–5 cm height). Tank mixes of oxadiazon and oxyfluorfen with different concentrations of surfactant improved later growth stage plant control. Taken together, our study highlights several herbicides that can improve weed control and may be used as chemical solutions alongside diversified crop rotation options. Thus, they may aid in preventing the spread and further buildup of S. rostratum field populations.

Three yearling Cheviot × Suffolk ewes and three Columbia wethers were confined in metabolic cages and fed ad libitum fresh and dried marrow-stem kale (Brassica oleracea var. acephala D.C.) harvested in mid- and late October. Chemical analyses of the forages indicated no marked effects on any of the plant constituents due to drying or advancing maturity. Digestibility measurements demonstrated that marrow-stem kale (MSK) was a highly digestible material with an average dry matter digestibility of 78%. The fresh forages had higher (P < 0.05) dry matter and gross energy digestibility values than the dried form. Dry matter digestibility coefficients were higher (P < 0.05) for late October as compared with the earlier harvest. A trend toward higher (P > 0.05) voluntary intake values due to drying maturity was observed with an average relative intake of 80%. The nutritive value index averaged 65, thus indicating a digestible energy intake similar to a high-quality (legume) forage.

Morocco has a large number of edible weeds, but seventeen are mostly eaten by the population, collected for sale in different provinces, or even exported. Eight weeds have edible shoots while the others have edible stems, fruits, roots, flowers, or petioles. Thirteen weed species are marketed either seasonally or throughout the year and generate money for the people. Morocco's tassel grapehyacinth bulbs and products extracted from pennyroyal mint are exported. Further research should focus on the nutritive value of these weeds and their economic role in the country.

Nutmeg is a source of income for some people in South Aceh, and some types of nutmeg, like mace nutmeg, are of better quality. Mace nutmeg is also an agricultural community with great economic value and benefits for humans, as it can be processed into spices and herbs. A range of products includes nutmeg oil and medicines. The harvesting and drying of mace nutmeg, which is still considered a problem by nutmeg growers, cannot be isolated from the processing of the basic ingredients. The natural process of drying mace nutmeg involves the use of sunshine, which necessitates a considerable drying time. Therefore nutmeg farmers frequently complain of erratic weather, especially during the wet season. The constant rain can cause the mace to rot, causing the nutmeg farming community's revenue to become unstable. Methods and steps of research work starting from the study of literature, determination of design specifications, hardware design, software design, toolmaking, tool testing.Good results were reached with the dryness of the mace nutmeg, which can be adjusted, and without putting into account the weather in the drying process, which is usually done with the heat of the sun, per the results of the testing of the designed tools.The average dryness of mace nutmeg is at a temperature of 45 percent with a time of 4 hours and a capacity of 100 grams; according to the test results of the automatic mace drying machine, it produces 50 grams of dry mace.

Synthetic herbicide, the most popular weed control, causes environmental hazards. The use of allelopathy in controlling weeds is a possible alternative for sustainable weed management. The study was conducted to determine the allelopathic potentials of identified invasive weed species in terms of percent and rate of germination, plant height, length of leaves and roots and percent mortality of grasses, sedges, and broadleaves. The treatments were: T0-Pre/Post-emergence Herbicide, T1Tap Water, T2-Mimosa pudica extract,T3-Lantana camara extract,T4-Chromolaena odorata extract. These were compared according to their effects on Cenchrus spinifex, Conyza canadensis, Impatiens wallerana and Cyperus rotundus. Data were analyzed using Analysis of Variance (ANOVA) for Completely Randomized Design. A further test was done using Duncans Multiple Range Test (DMRT). For germination, Lantana camara is effective in reducing the percent germination and prolonging germination rate of most common weed species. On the other hand, Chromolaena odorata is effective in reducing the percent germination and prolonging the germination rate of Impatiens wallerana, while Mimosa pudica was effective against Cenchrus spinifex and Cyperus rotundus. For growth and development, Mimosa pudica was found to be the most effective in all common weed species, except for Cyperus rotundus where Chromolaena odorata was most effective on reducing the length of leaves and roots, and above ground fresh weight. Furthermore, Chromolaena odorata was found effective against both Cyperus rotundus and Conyza canadensis while Mimosa pudica was effective against Cenchrus spinifex in terms of percent mortality. Thus, such potential of invasive weed species for weed management should be utilized.

Two trials were conducted to evaluate the voluntary intake and digestibility of kochia (Kochia scoparia) as hay or silage for sheep. In Trial 1, kochia (KOC) hay substituted for alfalfa hay (AA) at 0, 25, 50 or 75% of complete diets, or 50% AA or 50% KOC with barley (BAR) were fed to 24 mature wethers in a completely randomized design experiment. As the level of KOC in the diet increased, dry matter intake (DMI) of wethers decreased linearly. There were no differences (P > 0.05) in dry matter or fiber digestibilities among the four diets containing AA and KOC hay. Nitrogen and gross energy digestibilities increased linearly (P < 0.05) with decreasing levels of dietary KOC. In trial 2, KOC silage prepared from two ecotypes of KOC (southern and northern), cut at two different dates and fed in a 50:50 combination with AA silage were compared with a diet containing AA silage. DMI and nutrient digestibilities of the AA silage diet were higher (P < 0.05) than those for the diets containing KOC. Results indicate that KOC hay can be fed in high forage or concentrate diets at levels between 25 and 50% of the diet without adverse effects on intake or digestibility. Results also demonstrate that KOC can be preserved by ensiling and that KOC silage can be used in combination with AA silage in diets for sheep. Key words: Kochia, sheep, digestibility, hay, silage
