“…The highervalues on yield characteristics viz., head diameter, total number of seeds head -1 , number of filled seeds head -1 , percentage of filled seeds, test weight and also higher seed yield and stalk yieldwere observed under the treatment combination of sole sunflower (60 x 30 cm) with application of 40 kgS ha -1 (M 1 S 2 ) due to higher yield characteristics and noncompetition effects in using the available resource and optimum supply of sulphur. The minimum values for yield attributes, seed yield and stalk yield were recorded under the treatment combination of sunflower(120 x 30cm) intercropped with three rows of green gram along with application of S at0 kg ha -1 (M 4 S 0 )which could be due to inadequate availabilityof nutrients (Anas et al, 2017). The similar trend of result was noticed by Singh et al, (2013).…”

A field experiment was carried out during Mar-May, 2019 at the Experimental Farm, Department of Agronomy, Faculty of Agriculture, Annamalai University, Annamalai nagar-608002, to study the effect of different planting geometry and sulphur levels in sunflower + greengram intercropping system on the growth and yield attributes and yield of sunflower. The experiment consisted of twenty treatments and were laid out in factorial randomized block design with two replications. The treatment consisted of Factor A(different plant geometry levels): M1 - sole sunflower (60 x 30 cm),M2 - sunflower (60 x 30 cm) + 1 row of greengram, M3 - sunflower (90 x 30 cm) + 2 rows of greengram, M4 - sunflower (120 x 30 cm) + 3 rows of greengram, M5 -sole greengram and Factor B (sulphur levels): S0 - 0 kg S ha-1, S1 - 20kgS ha-1,S2 - 40kg S ha-1 and S3 - 60kg S ha-1.The results revealedthat growth, yield attributes and yieldwere significantly influenced by different plant geometry and various sulphur levels. Among the different planting geometry levels tried, sole sunflower (60 x 30 cm) (M1 ) significantly recorded maximum growth and yield attributes and yield of sunflower. With regard to various sulphur levels tried, application of sulphur at 40 kg ha-1 (S2 ) significantly recorded maximum growth and yield attributes and yield of sunflower. Interaction between planting geometry and sulphur levels were significant.Among the treatment combinations tried, sole cropping of sunflower (60 x 30 cm) along with application of S at40 kg ha-1 (M1 S2 )had a spectacular effect on growth and yield attributes, ultimately leading to maximum seed yield(2152 kg ha-1). The minimum growth attributes were recorded in sunflower(120 x 30 cm) intercropped with three rows of greengram along with application ofSat 0 kg ha-1 (M4 S0 ).

“…In other words, drip fertigation with high plant population is an important attribute to save nitrogen with sustainable yield for arid culture. Many experiments have conducted to find agronomic practices, high planting density, diversified planting geometry [181] organic fertilizers and improvement of application method of nutrients are helpful to regulate cotton yield for reduced nitrogen conditions in the Yellow River valley, China [11,12,140].…”

Nitrogen is the main limiting nutrient after carbon, hydrogen and oxygen for photosynthetic process, phyto-hormonal, proteomic changes and growth-development of plants to complete its lifecycle. Excessive and inefficient use of N fertilizer results in enhanced crop production costs and atmospheric pollution. Atmospheric nitrogen (71%) in the molecular form is not available for the plants. For world’s sustainable food production and atmospheric benefits, there is an urgent need to up-grade nitrogen use efficiency in agricultural farming system. The nitrogen use efficiency is the product of nitrogen uptake efficiency and nitrogen utilization efficiency, it varies from 30.2 to 53.2%. Nitrogen losses are too high, due to excess amount, low plant population, poor application methods etc., which can go up to 70% of total available nitrogen. These losses can be minimized up to 15–30% by adopting improved agronomic approaches such as optimal dosage of nitrogen, application of N by using canopy sensors, maintaining plant population, drip fertigation and legume based intercropping. A few transgenic studies have shown improvement in nitrogen uptake and even increase in biomass. Nitrate reductase, nitrite reductase, glutamine synthetase, glutamine oxoglutarate aminotransferase and asparagine synthetase enzyme have a great role in nitrogen metabolism. However, further studies on carbon–nitrogen metabolism and molecular changes at omic levels are required by using “whole genome sequencing technology” to improve nitrogen use efficiency. This review focus on nitrogen use efficiency that is the major concern of modern days to save economic resources without sacrificing farm yield as well as safety of global environment, i.e. greenhouse gas emissions, ammonium volatilization and nitrate leaching.

Ecosystem exposure to a biological invasion such as plant invasion could contribute to the extinction of native species and loss of productivity and ecosystem balance. Solidago canadensis (S. canadensis) is a highly invasive species that has formed monocultures in China, Europe, Asia, Australia, and New Zealand. It was designated as a notorious invasive species by the Chinese government. It has adversely affected the agroecosystem’s ability to germinate various plant seeds, including wheat, lettuce, and pepper, which could lead to food insecurity. This study was conducted to control the invasive species S. canadensis by utilizing a competitive species, Sorghum bicolor (S. bicolor) as a cover plant. Sorghum bicolor exudes allelochemicals such as sorgoleone from its roots which suppress the photosystem II activity of nearby plants. The synthesis of sorgoleone depends on a supply of nitrogen. The present study involved the cultivation of S. bicolor alongside the invasive species S. canadensis, with three different invasion levels (high, medium, and low) and three different nitrogen forms (ammonical, nitrate, and combined ammonical and nitrate nitrogen) applied as a modified Hogland solution. S. bicolor expressed higher performance over the invasive species under ammonical and combined nitrogen forms under low and medium invasion levels. Furthermore, even at greater levels of invasion, S. bicolor was not suppressed by S. canadensis. However, the plant height and dry biomass of S. bicolor were significantly high across both nitrogen forms. Leaf area, CO2 uptake, and photosystem II activity of S. canadensis were unable to sustain its growth under the low invasion condition. The plant biomass of S. canadensis was suppressed by up to 80% and the relative dominance index of S. bicolor was 5.22 over S. canadensis. There was a strong correlation between CO2 uptake, leaf area, and plant biomass. Principal component analysis showed that the first four components had a total variance of 96.89%, with principal component 1 (PC1) having the highest eigenvalue at 18.65. These promising findings suggested that S. bicolor, whose high intensity might be employed to control the invasion process for environmental safety, might be able to recover the barren ground that S. canadensis had invaded.
