Potassium (K) is the most neglected nutrient in Indian agriculture and accounts only 10% of the total fertilizer use. The increased cropping intensity and use of high yielding cultivars since the green revolution led to heavy withdrawal of K from soil. Persistent K mining over the past six decades has mined soil K level in many cultivated areas and continuously transforming sufficiency into deficiency. A recent soil test a little over 1 lakh samples from 33 states of India have categorized 41.1%, 29.3%, and 29.5% of soil samples as low, medium and high in available K respectively. Further, the trend of soil available K status showed a persistent decline in percentage of area under high and medium soil K. Consequently, the evidence of rice crop responding to K nutrition is increased. This review attempts the nexus of K nutrition in rice for devising strategies for potassium management in rice-based cropping systems in the country.

The Impact

Soil health and fertility is the basis for sustainable profitability of the farmers.Hence, there is a need for balanced use of fertilizers, keeping this government of India introduced Soil Health Card Scheme across India. On 5th December 2015 the ministry of agriculture introduced the soil health card (SHC) scheme.Some farmers complained that the soil test values are not representative of their fields and they also complained that the field staff are not collected soil samples in their presence.In this background an attempt was made to study the impact on socio-economic conditions of the small and marginal farmers.Total of 120 respondents was selected in Ekangarsarai block, Nalanda district, Bihar by purposive sampling method. The data was collected from them and analyzed using MS-excel.Given the short duration of the scheme, knowledge levels are good. At the same time participation of farmers in meetings, exposure visits are not high. Awareness campaigns need to be organized on content of SHCs, use of recommended practices, reduction in fertilizer use and costs and increase in profitability.

Agriculture Development

Technology united with research and development has evolved as a grave differentiator of the agriculture sector in India including production, processing, and agriculture packing and marketing of given crops. Near about 50 percent of the Indian workforce was engaged in the agriculture sector but its share in GDP was only 14 percent, much lower in comparison to former. Though, certain agriculture items showed a steady annual increase in terms of kilograms per hectare. Agriculture transformed significantly over the past few decades but when it comes to investment in research and development there is a lot more which needs to be done. The paper analyzes the role of various research and development institutions in boosting the growth of the agriculture sector that helps in attaining sustainable agriculture development and self-sufficiency in the production process since independence. It also focusesed on the various issues faced by these development institutions. The findings unveiled that since independence a lot more was done to boost the research and development in the agriculture sector at both the center and state levels but a proper implementation of these policies along with transparency could bring more desirable outcomes than were gained at present.

Quantitative relationships between soil test phosphorus (STP) methods are needed to guide P management especially in manured soils with high P. Our objectives were: (i) to compare amounts of P extracted by different methods; (ii) to develop and verify regression equations to convert results among methods; and (iii) to establish environmental P thresholds for different methods, in manured and non-manured soils of Manitoba. We analyzed 214 surface soil samples (0–15 cm), of which 51 had previous manure application. Agronomic STP methods were Olsen (O-P), Mehlich-3 (M3-P), Kelowna-1 (original; K1-P), Kelowna-2 (modified; K2-P), Kelowna-3 (modified; K3-P), Bray-1 (B1-P) and Miller and Axley (MA-P), while environmental STP methods were water extractable (W-P), Ca Cl2 extractable (Ca-P) and iron oxide impregnated filter paper (FeO-P) methods. The different methods extracted different amounts of P, but were linearly correlated. For an O-P range of 0–30 mg kg-1, relationships between O-P and other STP were similar for manured and nonmanured soils, but the relationships diverged at higher O-P levels, indicating that one STP cannot be reliably converted to another using a single equation for manured and non-manured soils at environmentally critical P levels (0–100 mg kg-1 O-P). Suggested environmental soil P threshold ranges, in mg P kg-1, were 88–118 for O-P, 138–184 for K1-P, 108–143 for K2-P, 103–137 for K3-P, 96–128 for B1-P, 84–111 for MA-P, 15–20 for W-P, 5–8 for Ca-P and 85–111 for FeO-P. Key words: Phosphorus, soil test phosphorus, manured soils, non-manured soils, environmental threshold

The fertilizer market in Hungary is rather concentrated, which has a strong influence on the price of the fertilizer. Our domestic fertilizer use is primarily determined by that of nitrogen. The use of phosphorus is also significant but the trends in the use of potassium do not match the total quantities applied in individual years. Consequently, it can be concluded that the majority of farmers still focus on the application of nitrogen and also apply phosphorus but either neglect or do not pay enough attention to potassium fertilization. The changes in fertilizer prices between 2006 and 2017 can be broken down into two periods. Until 2012 a very important and dynamic increase was observed as a result of which the prices of N, P and K fertilizers increased by 80-120%, 160% and about 120%, respectively. This was followed by a downturn in the market and in relation to 2012 prices there were 20-30/ decreases experienced until 2017 but the rate of this lagged behind the prices in other European countries. Owing to this trend the prices of N, P and K have increased by 60%, 100% and 80%, respectively, over the past ten years. The correlation between fertilizer application and the prices of fertilizers in any given year is low but there is a positive one observed between fertilizer application and the fertilizer prices in the preceding year. This means supposedly that farmers mostly buy the fertilizers they wish to apply not in the current but in the preceding year and store them until these are applied. There is a strong correlation seen between fertilizer prices and the prices of corn and wheat, which means that fertilizer traders also keep tabs on economic results and also increase fertilizer prices under the influence of higher prices. Furthermore, it can be claimed that there is no correlation between crude oil prices on the world market and domestic N fertilizer prices. This is an important factor since the primary base material of N fertilizers is natural gas and their production involves considerable energy costs as well. It can be seen, however, that this is not what determines our domestic fertilizer prices, which can be explained by the fact that the price calculations by the determining actors on the Hungarian fertilizer market is not based on costs but on the demand.

India is marching ahead to face the enormous triple challenges of sustainable increased agriculture and allied sector productivity, maintaining environmental sustainability and mitigating poverty. More than 70% rural households depend on agriculture and the contribution of Agriculture and allied sectors to total GDP (Gross Domestic Product) is 17%. The agriculture and allied sector not only meet the food and nutritional requirements of 1.3 billion Indian, it contributes significantly to production, employment and demand generation through various backward and forward linkage. To extend the benefit of first green revolution (1966-67) and to reduce the yield gap Bringing Green Revolution in Eastern India programme was launched under RKVY (Rashtriya Krishi Vikas Yojana) in 2010-11 comprising seven states namely Bihar, Eastern UP, Jharkhand, Odisha, Assam, Chhatisgarh and West Bengal. There was a need for a second green revolution to feed the growing population. The present study was conducted during 2020-21 in two blocks namely Jamankira and Jujomura in Sambalpur district of Odisha to compare the production and productivity of rice crop between the BGREI beneficiary and non beneficiary farmers. During 2012-13 and 2013-14, the BGREI programme was extended to 22 districts of Odisha and National Rice Research Institute (previously CRRI), Cuttack, Odisha is the nodal agency to guide, supervise, monitor and supervise technical interventions. BGREI consists of the following interventions such as (i) Block demonstration (ii) Asset building (iii) Site specific activities (iv) Marketing support including post harvest management (v) Seed production and distribution (vi) Subsidy on need based inputs (vii) Training programme on cropping system based demonstration etc.

Natural Farming

Crisis of Indian agriculture is very pertinent at this moment as green revolution is gradually losing its hope. Excessive, pointless exploitation of broods of green revolution has left bad footprints on country’s food security and environmental safety. With the motto to ensure food security by reviving Indian agriculture in environmentally safe way as well as to release farmers from debt cycle and suicides, zero budget natural farming (ZBNF) has come in the picture, which discards uses of all the chemical farming inputs and relies on natural way of farming i.e. rejuvenating soil and crop health through its own practices (Jivamrita, Bijamrita, mulching, soil aeration, intercropping, crop diversification, bunds, bio-pesticides etc.). ZBNF movement right now is the most popular agrarian movement which begun in 2002 in Karnataka and later successfully spread in many states (specially, of South India) of the nation through numbers of trainings, demonstrations and various promotional activities. Successful outcomes from farmers’ fields of south Indian states like Andhra Pradesh, Karnataka etc. are encouraging and grabbing attention of farmers, public and private organisations towards ZBNF in recent times. Yet, various controversies regarding its transparency,      inadequate information, efficacy, practices, idealisms, even the term ‘zero budget’ etc. have agglutinated around ZBNF over the years since it debuted. Critics in fact have cited several references of drastic yield reductions with ZBNF practices in many places. Adequate scientific evaluation or monitoring of ZBNF’s successes or failures through multi-locational trials is now therefore the needful before allowing or restraining its run in Indian agriculture.

The paper finds that trade liberalization in Indian agriculture has expectedly promoted specialization in areas of advantage, namely the superior cereals and gone against diversification towards oilseeds. Trade liberalization seems to have picked up where green revolution left off while diversification suffered portending some well known ill effects. Since oilseeds that lose in the process and coarse cereals they replace and that have been on a decline for some decades are suited to dry environments whereas the superior cereals demand more water and other costly inputs, there is a need to seriously consider the concerns of diversity, sustainability and poverty in a heterogeneous agriculture when negotiating trade and designing policy.
