Sandy soils in coastal areas can be managed for peanut cultivation by minimizing the limiting factors. The study aimed to use organic soil amendments combined with weed control methods optimize peanuts' growth and yield sandy land. research was conducted area of Bengkulu, Indonesia, from September 2019 January 2020. Two experimental factors were arranged a completely randomized block design thr...
Organic apple production in the eastern US is small and is mostly based on existing varieties, which are susceptible to scab, and rootstocks, which are susceptible to fire blight. This requires numerous sprays per year of various pesticides to produce acceptable fruit. From 2014 to 2016, we tested different arthropod, disease and weed management programs in an advanced tall spindle high-density...
Approaches that involve manipulating T cells outside the body and then replacing them have shown promise. However, researchers worry that such cells could provoke autoimmunity because they don’t pass through negative selection, the weeding-out of self-targeted T cells in the thymus. Other concerns are that the re-introduced T cells won’t survive very long and that they won’t generate the memory...
The effect of tillage, crop establishment and weed management was studied on theperformance of wheat grown after soybean at New Delhi, India during 2010-11 to 2011-12.Sixteen treatment combinations involved 2 tillage, viz. conventional tillage (CT) and zero tillage(ZT), two crop establishment practices, viz. raised-bed and flat-bed and four weed management,viz. isoproturon + hand weeding, mesos...
Weeds constitute a serious problem to wheat crops and cause great loss the yield. Manual weeding is labor-intensive time-consuming. Chemical weed control has negative impact on both environment humans. Today agricultural sector requires non-chemical that safeguards consumers demand for high quality food products pay special attention safety. The objectives of study was evaluate performance an-e...
An experiment was conducted at College Farm, of Agriculture, Rajendranagar, Hyderabad during rabi 2020-21 on loamy sand soils to study energy balance weed management practices in mustard. The studies were determined by using direct and indirect energy. Among the different practices, Stomp 30 % EC as PE fb straw mulch 5 t ha-1 recorded higher input. This treatment followed Goal 23.5 Raft 6 ha-1....
This paper describes a dynamic simulation model that allows for comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems. The main outputs of the model include weed seed and plant densities and seasonal and annualised profit over the simulated planning horizon. Results broadly in...
Seeding rangeland following wildfire is a central tool managers use to stabilize soils and inhibit the spread of invasive plants. Rates of successful seeding on arid rangeland, however, are low. The objective of this study was to determine the degree to which water availability, invasive plant abundance, and seeding technology influence postfire seedling establishment. Across four fire complexe...
Tropical dry forests (TDFs) have been widely transformed by human activities worldwide and the ecosystem services they provide are diminishing. There has been an urgent call for conservation and restoration of the degraded lands previously occupied by TDFs. Restoration experiences aim to recover species diversity and ecological functions. Different restoration strategies have been used to maxim...
Plant morphogenesis requires differential and often asymmetric growth. A key role in controlling anisotropic expansion of individual cells is played by the cortical microtubule array. Although highly organized, the array can nevertheless rapidly change in response to internal and external cues. Experiments have identified the microtubule-severing enzyme katanin as a central player in controllin...
