Continuous use of chemical fertilizers without organic sources poses soil health issues whereas organic manures using alone without inorganics could not be able to fulfill the requirement of high nutrient demanding crops due to the bulk and slow-acting nature of these organic fertilizer sources. However, neither organic fertilizers nor inorganic fertilizers alone can maintain productivity. The major yield limiting factors in crops production in Indian soils are NPS deficiencies.

Rice residues are important natural resources, and recycling of these residues improves the soil physical, chemical and biological properties. Management of rice straw is a major challenge as it is considered to be a poor feed for the animals due to high silica content. A field experiment was conducted at Agricultural Research Station, Bhavanisagar during 2014-2015 and 2015-2016 to review the suitable rice residue management practices and nutrient dynamics by using combine harvester operated rice field after cultivating rice.

The major nutrients nitrogen, phosphorus and potash play an important role in nutrition of garlic plants in relation to growth, yield and quality of bulb. The organic manure is an ecofriendly, economically viable and ecologically sound that also played a significant role in soil biology, chemistry and physics.

The nutrient uptake processes of K, Mg, and Ca are strongly antagonistic resulting in a deficiency of the depressed nutrient [14]. A deficiency of one element could imply a relative or absolute excess of the others resulting in an imbalance for the plants [3]. A sufficient Ca concentration in soil or nutrient solution is important; however, major cations frequently interfere with Ca uptake [1].

The farmers are using local cultivators ie Jhain Mung which gives poor yield. Generally the farmers are not adopting any nutrient and biofertilizer application and YMV is the major reason for poor yield in this area. As the crop is grown in residual soil moisture, the crop faces water stress condition many times. One of the major constraints of poor yield and spread of green gram, is the non-availability of suitable high yielding variety to replace the traditional varieties.

Field studies were conducted on application of zinc and boron to summer rice crop on Alfisols at Naganahalli village, Mysore district, Karnataka. The results showed that external application of zinc as ZnSO4 @ 20 kg ha-1 and boron as borax @ 4 kg ha-1 significantly enhanced the plant height number of tillers hill-1 , grains per panicle, thousand grain weight, grain yield and straw yield of paddy. Further there was significant increase in major (N, P and K), secondary (S, Ca and Mg) and micronutrient (Zn, Cu, Fe, Mn and B) status of soils.

The autoplaque or autolysis of bacterial cell influences the evolutionary potential of clinically important bacteria. It serves as a selection pressure on a bacterial community and provides social goods (nutrients, secondary metabolites, free DNA) in environment. Therefore, it has a major impact on the ecological fitness of microbial communities; however its prevalence in microbial communities of degraded ecosystems is not known.

Interaction between soil microbes and minerals play a major role in environmental cycling processes, which leads to the mobilization of nutrients from soil components into available forms for biological uptake which enhances crop growth and yield. In the present study four (4) potassium solubilizing bacteria (KSB), eight (8) zinc solubilizing bacteria (ZnSB) and two (2) zinc solubilizing fungi (ZnSF) isolated from Rice, Maize, Cotton and Sorghum rhizosphere soil collected from Student and College farm Rajendranagar PJTSAU Hyderabad.

Rice-wheat (Oryza sativa L.-Triticum aestivum L.) rotation is the major production system in Asia, covering about 18 million ha. Continuous and conventional RWC system practice has witnessed a significant slowdown in the yield growth rate. The sustainability of this important cropping system is at risk due to second-generation problems (low fertility status, multiple nutrient deficiencies, and imbalanced use of fertilizers, ground water depletion at faster rate, soil salinization, and inadequate system diversity).

Banana is a highly exhaustive crop which requires large quantities of mineral nutrients for rapid growth and development, thus it readily responds to applied nutrients. Major nutrients like nitrogen, phosphorus and potassium play an important role in the vegetative and reproductive phases of crop growth, depending on the cultivar.

The major uses of soybean are as a source of edible oil and protein rich food, as well as cattle feed. The nutrient requirement and interaction of different nutrients under high phosphorus conditions were not worked out so far in soybean track. To improve the productivity levels of soybean it is imperative to assess the nitrogen and phosphorus requirement under high P fertility soils to obtain the potential yield by the farmers.

Soybean is one of the important oilseed crop in India, which plays a major role in supplementing the income of small and marginal farmers. One of the major constraints of traditional soybean farming is low productivity of local varieties and nutrient deficiency in soil. In this point of view Krishi Vigyan Kendra, Bidar conducted Front line demonstration at 145 farmer’s field to demonstrate production potential and economic benefit of improved technologies at adopted farmer’s field during 2012-13 to 2019-20 of seven years study in rainfed condition.

Plant nutrition plays a major role in quantitative and qualitative crop production in bringing sustainability and plants require seventeen essential elements for their normal growth and development. Among these, those elements required smaller in quantity is called micronutrients (Fe, Cu, Zn, Mn, B, Cl, Mo and Ni). Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants.
