| A cost-benefit analysis (CBA) of an investment in the protection of malleefowl and associated native vegetation in the Lachlan Catchment’s central-west yielded a benefit-cost ratio of 1.4. The CBA is based on project expenditures over the past four years coupled with benefit estimates from a recent Choice Modelling study in the Lachlan Catchment. The project targets the protection of malleefowl on private land which has not yet been surveyed but where the species is known to be present. The CBA is subject to significant uncertainty due to a lack of available data. Nonetheless, sensitivity analysis indicates that the BCR is consistently larger than unity, if marginal in some cases. This suggests that the project is a worthwhile investment at this early... |

| Larvae of the butterfly Erionota thrax, the banana skipper, destroy the leaves of bananas by eating them and forming massive protective rolls of leaf tissue. They were first observed in north-western Papua New Guinea in 1983 and over the next 6 years spread throughout the mainland at the rate of up to 500 km/year. E. thrax has also spread across the ocean to the east, to invade New Britain, Duke of York and New Ireland islands, and possibly Bougainville. As the banana skipper spread, it destroyed an average of some 60% of banana leaves, leading to both a serious delay in fruit maturation and reduced weight of banana bunches. Previous successful biological control of E. thrax when it invaded Mauritius, Hawaii, Guam and Saipan encouraged Papua New Guinea... |

| ABSTRACT Cereal-legumes intercropping is among the most economical and effective agronomic strategies to boost forage biomass production, nutritional quality and monetary returns. This review synthesizes the research findings on how intercropping affects productivity, quality, competitiveness and economic viability of sorghum-legumes mixed, row and strip intercropping systems under varied pedo-climatic conditions. Though component crops show yield reductions in row (additive and row-replacement series), mixed (seed blended crops) and strip intercropping systems, in general overall productivity per unit land area increases to a great extent. The significantly higher resource capturing with better utilization efficacy by intercrops in temporal and spatial... |

| ABSTRACT: The study aimed to highlight the impact of naphthalene acetic acid (NAA) and irrigation regimes on the productivity of coarse rice under agro-ecological conditions of Dera Ismail Khan, Pakistan. The experiment was comprised of two factors with four levels (0, 60, 90, 120 mL ha-1) of NAA and irrigation at the depths (60, 75, 90 and 105 cm) of soil profile. The data was interpreted to observe the plant height (cm), productive tillers (m-2), sterility percentage (%), biological yield (t ha-1), and grain yield (t ha-1) of coarse rice. The benefit cost ratio (BCR) was also calculated. The results indicated that the application of NAA was found very effective in improving paddy yield and hence resulted in better BCR value. The maximum paddy yield was... |

| The production performance of different sizes of broiler farms has been studied by collecting data from 60 broiler producers of Anand district during 2005. To examine production performance, the average feed conversion ratio, livability percentage, average body weight and age at marketing have been worked out. Though broiler production is capital-intensive, it has been found profitable. The average cost of production per broiler has been found to be ` 64 and per kilogram live weight of broiler as ` 32. The variable cost and fixed cost constitute 84.5 per cent and 15.5 per cent of total cost, respectively. The major cost components have been found as feed cost (58.6%), chick cost (21.5%) and depreciation on buildings (10.7%). The net profit per broiler as... |

| ABSTRACT: Herbicide resistance development among weeds, environmental contamination and health concerns due to the overuse of herbicides have led researchers to focus on ways to reduce herbicides to be sprayed for weed management. Adjuvants are best suited for that purpose, as they accomplish a crucial role in achieving satisfactory control of weeds by maximizing herbicidal activity. A two-year field investigation was carried out at the Agronomic Research Area, in the University of Agriculture, in Faisalabad, Pakistan during the winter of 2014 and 2015, with the objective to optimize the activity of two broad-spectrum herbicides at reduced dose (75% of the label mentioned rate) for weed control in wheat. Minimum weed density, weed dry weight and NPK uptake... |

| ABSTRACT: In direct seeded rice (DSR), flushes of weeds are encountered, and mostly subsequent herbicides need to apply to control weeds that appear later. A farmer friendly approach was hypothesized in present study to integrate the management strategies for water, soil and cost effective weed free rice production. Efficacy of various herbicides in weed control to improve the performance of aerobic rice grown under varying tillage and alternate water regimes was evaluated. Five weed management techniques (weedy check, weed-free, pendimethalin followed by manual weeding, pendimethalin + bispyribac sodium (BS) + bensulfuron (B) and pendimethalin + MCPA) were carried out within the alternate wetting and drying (AWD) regimes (15 and 20 cm depth) under two... |
