challenges viz. increased agricultural demand necessitated by a growing
population, extreme weather and growing conditions related to climate
change and limited natural resources. Due to rapid depletion of agricultural
areas, water and soil quality by means of ever-increasing population and an
excessive addition of chemical fertilizers, a rehabilitated attention is a need of
the hour to maintain sustainable approaches in agricultural crop production.
Biostimulants are materials, other than fertilizers, that promote plant growth
when applied in low quantities. It aims to enhance nutrient efficiency, abiotic
stress (i.e., frost, drought, salinity) tolerance and crop quality traits regardless
of its nutrients content. Main objective behind using these products is not
to supply nutrition but rather to favor and stimulate the metabolism of the
plant, decrease plant stress etc. Industry focus is to develop and commercialize
biostimulants that are compatible with advanced farming techniques used in
integrated crop management (ICM), the cornerstone of sustainable agriculture.

Great potential of the crop is not yet fully exploited under Indian condition mainly because of lack of research on biotic and non-biotic stresses. As the people are conscious about their health, quinoa is gaining the increased demands in domestic and international market. Introduction of quinoa in the cropping systems adds to additional income to the farmer as the B:C ratio is improved. The cultivation of quinoa provides an alternative for countries with limited food production which are therefore forced to import or receive food aid.

In such situation Farmer Produces Organization plays an important role in promoting and strengthening member based institution of farmers. This business form allows 10 or more producers to form an organisation as per its memorandum of association. FPO's can link smallholder's farmers to local, regional, national and international markets effectively if there is no political interference. FPOs which are formed as Farmer Producer Company (FPCs) allow its member to access financial and other input services. To surpass this effective and viable profit making FPCs needs to be competent with other companies and rivals in the market and has a huge potential to capture the future food retails not only in India but in the world.

They compete with main crop plant for water, nutrients, air and light resulting in poor crop growth and development. Weeds associated with mustard crop, categorized as broad leaved, narrow leaved, sedges and grassy weeds resulting in poor grain yield. Total eleven weed species were found in mustard crop field belonging to different family and genera. The experiment was conducted in Rabi season during the year 2018-2019. Maximum number of species belongs to broad leaved category of weeds classification. Three species were found to be grassy weeds followed with sedges. The weeds depending upon the type, density and duration of competition accounts for 23-70 per cent reduction in yield of mustard. Three species belongs to Poaceae family followed by Chenopodiaceae, Compositae, Asteraceae, Convolvulaceae, Fabaceae, Polygonaceae and Cyperaceae. Among the grassy weeds, Cynodon dactylon (L.) Pers. was the predominant weed followed by Polypogon monspeliensis and Phalaris minor. Cyperus rotundus L. was the only sedge present in the experimental field. Among the broadleaved weeds, Chenopodium album L. was the dominant one followed by Anagallis arvensis L., Parthenium hysterophorus L., Convolvulus arvensis, Melilotus albam Vicia hirsute and Rumex sp.

The research was conducted using Randomized Block Design (RBD) replicated thrice, which comprised of two factors. The first factor was dosage of the nitrogen with three levels i.e., 50, 75, 100 kg N ha. The second factor was different inter row spacing i.e., 30cm x 20cm, 40cm x 20cm and 50cm x 20cm. The results showed that the growth and yield attributes have been found to be significantly affected by different treatments. Application of 100 kg ha Nitrogen with 50cm x 20cm spacing recorded significantly higher plant height and number of branches. The total fresh leaf yield and fresh stem yield per hectare increased significantly with application of 100 kg ha Nitrogen with 30cm x 20cm spacing.

Stevioside extract from stevia is considered to be 300-350 times sweeter than sugar. It is safe for use by both diabetics and hypo glycaemics due to its low glycaemic index. Stevia has some bitter aftertaste along with sweetness due to the presence of some essential oils, tannins and flavonoids.Methods: Field experiment was conducted at Eastern Block of Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Prayagraj during Zaid 2018. The experiment was carried out in randomized complete block design comprising of three N levels i.e. 50, 75 and 100 kg N/ha and inter row spacing of 30, 40 and 50 cm with 20 cm of plant to plant spacing. The study was carried out to find out response of nitrogen levels and spacing on stevia.Result: Maximum plant height (51.24 cm), leaf area (4596.99 cm2) was observed with treatment 100 kg N ha-1 at 50 cm x 20 cm ...

Climate change is taking a toll on India’s agricultural production and productivity. Intergovernmental panel on climate change (IPCC) has projected that by the end of 21st century temperature in India is likely to increase by 3-4°C which would lead to a loss of 3-26% in net agricultural revenues. Aggravated climatic factors will ultimately decline plant productivity, which will result in increased prices and unaffordable rates for the common population. The absence of mitigation and adaptation measures may result in lower farm income by 12-40% in the coming years. This issue is an important concern for livelihood, economic development and ensuring food and job security of an agrarian nation like India. The causes that ultimately are contributing to increase in greenhouse gases, deterioration of soil and water ecology must be identified and ...

Black wheat is one of them which are gaining importance among health conscious people due to its multiple health benefits. Morphologically it is similar to white wheat in all aspects except its grain color and nutritional composition. Black wheat variety named ‘Nabi MG’ is rich in anthocyanins (imparting color to grains), protein, dietary fibre, iron and zinc content. It has immense biological value and can become health improving food supplement. It has ability to combat and address global and national challenge of malnutrition.

In such situation Farmer Produces Organization plays an important role in promoting and strengthening member based institution of farmers. This business form allows 10 or more producers to form an organisation as per its memorandum of association. FPO's can link smallholder's farmers to local, regional, national and international markets effectively if there is no political interference. FPOs which are formed as Farmer Producer Company (FPCs) allow its member to access financial and other input services. To surpass this effective and viable profit making FPCs needs to be competent with other companies and rivals in the market and has a huge potential to capture the future food retails not only in India but in the world.

They compete with main crop plant for water, nutrients, air and light resulting in poor crop growth and development. Weeds associated with mustard crop, categorized as broad leaved, narrow leaved, sedges and grassy weeds resulting in poor grain yield. Total eleven weed species were found in mustard crop field belonging to different family and genera. The experiment was conducted in Rabi season during the year 2018-2019. Maximum number of species belongs to broad leaved category of weeds classification. Three species were found to be grassy weeds followed with sedges. The weeds depending upon the type, density and duration of competition accounts for 23-70 per cent reduction in yield of mustard. Three species belongs to Poaceae family followed by Chenopodiaceae, Compositae, Asteraceae, Convolvulaceae, Fabaceae, Polygonaceae and Cyperaceae. Among the grassy weeds, Cynodon dactylon (L.) Pers. was the predominant weed followed by Polypogon monspeliensis and Phalaris minor. Cyperus rotundus L. was the only sedge present in the experimental field. Among the broadleaved weeds, Chenopodium album L. was the dominant one followed by Anagallis arvensis L., Parthenium hysterophorus L., Convolvulus arvensis, Melilotus albam Vicia hirsute and Rumex sp.

The research was conducted using Randomized Block Design (RBD) replicated thrice, which comprised of two factors. The first factor was dosage of the nitrogen with three levels i.e., 50, 75, 100 kg N ha. The second factor was different inter row spacing i.e., 30cm x 20cm, 40cm x 20cm and 50cm x 20cm. The results showed that the growth and yield attributes have been found to be significantly affected by different treatments. Application of 100 kg ha Nitrogen with 50cm x 20cm spacing recorded significantly higher plant height and number of branches. The total fresh leaf yield and fresh stem yield per hectare increased significantly with application of 100 kg ha Nitrogen with 30cm x 20cm spacing.

The main aim of carbon farming is to apprehend the unwanted carbon dioxide (CO2) from the atmosphere which is accountable for global warming and if carbon farming is combined with greater reduction in fossil fuels emission then it can help us in bringing back from the brink of disaster and return our atmosphere to the “magic number” of 350 parts per million of carbon dioxide.

Stevioside extract from stevia is considered to be 300-350 times sweeter than sugar. It is safe for use by both diabetics and hypo glycaemics due to its low glycaemic index. Stevia has some bitter aftertaste along with sweetness due to the presence of some essential oils, tannins and flavonoids.Methods: Field experiment was conducted at Eastern Block of Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Prayagraj during Zaid 2018. The experiment was carried out in randomized complete block design comprising of three N levels i.e. 50, 75 and 100 kg N/ha and inter row spacing of 30, 40 and 50 cm with 20 cm of plant to plant spacing. The study was carried out to find out response of nitrogen levels and spacing on stevia.Result: Maximum plant height (51.24 cm), leaf area (4596.99 cm2) was observed with treatment 100 kg N ha-1 at 50 cm x 20 cm ...

Climate change is taking a toll on India’s agricultural production and productivity. Intergovernmental panel on climate change (IPCC) has projected that by the end of 21st century temperature in India is likely to increase by 3-4°C which would lead to a loss of 3-26% in net agricultural revenues. Aggravated climatic factors will ultimately decline plant productivity, which will result in increased prices and unaffordable rates for the common population. The absence of mitigation and adaptation measures may result in lower farm income by 12-40% in the coming years. This issue is an important concern for livelihood, economic development and ensuring food and job security of an agrarian nation like India. The causes that ultimately are contributing to increase in greenhouse gases, deterioration of soil and water ecology must be identified and ...

It has spread to various states in India with huge success in southern India, especially in Karnataka where it was evolved for that first time. It is an extreme form of low external input sustainable agriculture (LEISA). External inputs are not purchased from outside, rather all inputs are locally available in a symbiotic way which helps in breaking the vicious debt trap of many small farmers. ZBNF method promotes soil aeration, increased water retention, multi-cropping, mulching, reduced irrigation and deep ploughing. Palekar has faced some resistance due to usage of term ‘zero budget, as many questioned the accuracy of the term as some costs are involved in rearing and maintaining livestock. Recently Subhash Palekar changed the name of ZBNF to Subhash Palekar Natural Farming (SPNF). This new name has created confusion and still many including state and central government continue to use the term ZBNF. Government is promoting this farming practice to maintain the ecosystem balance and sustainability and productivity of agricultural system in long term which is declining rapidly due to increased and imbalanced use of chemical fertilizers, hybrid seeds and pesticides. This farming may have low investment but requires lot of hard work and labour. Reports indicate that the drought-prone regions in India are seeing promising changes already in farms with the ZBNF.
