Ebook "Organic crop production – Ambitions and limitations" has been written to provide scientifically based information on organic agriculture such as crop yields, food safety, nutrient use efficiency, leaching, long-term sustainability, greenhouse gas emissions and energy aspects. A number of scientists working with questions related to organic agriculture were invited to present the most recent research and to address critical issues.

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.

This study clearly showed the benefit of P availability in combination with Rhizobium on leaf area, leghaemoglobin content, nitrate reductase activities of leaves and nodules, fresh and dry weight of nodules and fresh weights of stem + leaves at vegetative and flowering stages. Yield components, pod number and seed number were significantly increased by P availability by fertilizer alone and in combination with Rhizobium or through Rhizobium +Microphos.

Nitrogen is a major essential yield limiting nutrient in crop production, it serves as a constituent of many plant cell components, such as amino acids and nucleic acids. Hence it is important to improve the productivity as maize is an exhaustive crop. The low productivity of maize during kharif season is attributed to a wide range of constraints including the low nitrogen use efficiency.

Nitrogen and Phosphorus are the two most essential nutrients in popcorn. Others nutrients that are limiting in soil and require fertilization for popcorn are K, S, Zn, Fe, etc. To produce one tone of grain and dry matter, maize crop withdraws 8.0 kg of N, 2.5 kg of P2O5 and 18 kg of K2O from the soil.

The greatest limitation for increasing the productivity of this crop is inadequate supply of nutrients and maintenance of optimum plant population. In view of above the present investigation was carried out to study the effect of plant density and nutrient management on growth and yield of sunflower.

The crop yield should be limited by the available nitrogen within the soil. Yoshida (1972) reported that nitrogen plays an important role in developing yield capacity and maintaining the photosynthetic activity during grain filling stage of the crop. Nitrogen application can improve the root system, so that water and nutrient absorption are facilitated.

Soil testing is a useful tool that can help to ensure the efficient use of applied plant nutrients. Soil tests measure the quantity of a nutrient that is extracted from a soil by a particular extractant. The measured quantity of extractable nutrient in soil is then used to predict the crop yield response to application of the nutrient through fertilizer, manure and any other amendments. As soil test levels increase for a particular nutrient, the expected crop yield response to additions of that nutrient decreases.

Cassava (Manihot esculenta Crantz) is a perennial shrub and a tuberous root crop well adapted to poor soils and is relatively tolerant to drought, the crop is usually grown under marginal soil and climatic conditions and often with very limited inputs of fertilizers and pesticides. In India, cassava is cultivated in varied agro climatic and pedogenic environments. In Tamil Nadu, it is cultivated mainly for industrial uses, cassava is grown in black soils (Vertisols) and red soils (Alfisols).

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.

Drip irrigation has the greatest potential for the efficient use of water and fertilizers. The limited area of wetting under trickle irrigation reduces the active root zone and also the foraging area of plants to draw water and nutrients from the soil. For minimizing the cost of irrigation and fertilizers, adoption of drip irrigation with fertigation is essential which will maximize the nutrient uptake, while using minimum amount of water and fertilizer.

Plants in nature are constantly exposed to a variety of abiotic and biotic stresses which limits their growth and production. Enhancing crop yield and production to feed exponentially growing global population in a sustainable manner by reduced chemical fertilization and agrochemicals will be a big challenge. Recently, the targeted application of beneficial plant microbiome and their cocktails to counteract abiotic and biotic stress is gaining momentum and becomes an exciting frontier of research.

A pot culture study was conducted in 20 acidic soils of Senapati District of Manipur, India during rabi season of 2013-14 to estimate the critical limit of P in soil and pea plant for predicting the response of pea (Pisum sativum L.) to P application as well as to study the effect of P application on dry matter yield and uptake of nutrients in pea crop. The experimental soil was acidic in nature, electrical conductivity of the soil was in safe limit for crop growth. The organic carbon status was almost high and soil was clay in textural class.

The investigation was under taken during kharif and rabi season 2017-18 at Shaheed Gundadhur College of Agriculture and Research Station, Jagdalpur (Chhattisgarh). The pot experiment, during kharif season with transplanted rice, was laid out under Completely Randomized Design (CRD) with three replications and 11 treatments comprised with keeping one treatment of application of all nutrients (N, P, K, S, Ca, Mg, Cu, Zn, B, and Mo) in optimum level and other treatments were formulated by sequentially omitting each nutrient from all nutrients applied.
