Weeds are a major constraint to the success of dry-seeded rice (DSR). The main means of managing these in a DSR system is through chemical weed control using herbicides. However, the use of herbicides alone may not be sustainable in the long term. Approaches that aim for high crop competitiveness therefore need to be exploited. One such approach is the use of high rice seeding rates. Experiment...

Background: Chickpea is a cool season legume crop and grown in several countries worldwide as food source. Seed the main edible part of plant rich source protein, carbohydrates minerals especially for vegetarian population. The current study aimed to effect seed rate spacing on yield attributes chickpea. Methods: research was carried out at Research Farm, Department Agriculture, Maharishi Marka...

to evaluate the effect of gamma rays on the seeds and amounts of nitrogen on growth and yield of chamomile (chamomilla recutita synonym matricaria chamomilla), a factorial experiment was conducted based on randomized complete block design with three replications at the research farm of agriculture college of shahid-beheshti.-urmia in 2010. treatments were gamma rays from cobalt-60 on chamomile ...

A randomized complete block design was used to characterize the relationship between production of total phenolics, flavonoids, ascorbic acid, carbohydrate content, leaf gas exchange, phenylalanine ammonia-lyase (PAL), soluble protein, invertase and antioxidant enzyme activities (ascorbate peroxidase (APX), catalase (CAT) and superoxide dismutase (SOD) in Labisia pumila Benth var. alata under f...

Volunteer potatoes are difficult to control in onions and can greatly reduce onion growth and yield. Herbicides and cultivation were evaluated for control of simulated volunteer potatoes in onions in 1996 and 2000. Three interrow cultivations did not control potatoes in the onion row and the remaining plants reduced onion yield 50 and 73% compared with the hand-weeded checks. Three applications...

Plant growth promoting rhizobacteria (PGPR) mediate the soil processes such as decomposition, nutrient mobilization, mineralization, solubilization, nitrogen fixation and growth hormone production. Microorganisms having the phosphate solubilizing capacity can convert the insoluble phosphates into soluble forms through the production of organic acids. Inoculation of seed with P-solubilizing micr...

During the kharif season of 2020-22, a field experiment with soybean in soybean-wheat cropping system was conducted at ICAR-Indian Institute Soil Science, Bhopal, (M.P.) to assess effect different levels crop residue retention treatments and nutrient doses on growth parameters, physiological indices, yield attributes, profitability soybean. The laid out Factorial Randomized Block Design (FRBD) ...

Many communities in the Midwestern United States obtain their drinking water from shallow alluvial wells that are vulnerable to contamination by NO3-N from the surrounding agricultural landscape. The objective of this research was to assess cropping systems with the potential to produce a reasonable return for farmers while simultaneously reducing the risk of NO3-N movement into these shallow a...
