Performance of modern cultivars in terms of yield under organic farming differs from that of conventional system. As the demand for organic rice is increasing, so to maintain high productivity, there is a need to evaluate modern high yielding rice varieties under organic farming systems. Field experiments were carried out using randomized complete block design involving fourteen rice (Oryza sativa L.) varieties including seven coarse and seven fine grain types with three replications under organic farming systems for three years (2013-2015).

Rice (Oryza sativa L.) is one of the most important staple food crops worldwide. Nitrogen (N) is the most important nutrient in irrigated rice cultivation. Current high yields of irrigated rice are often associated with applications of higher doses of fertilizer N, as nearly 30-40 percent of applied nitrogen is actually utilized by the crop; even with the best agronomic practices. It has always been a problem to raise the utilization rate of the rice plant and to increase efficiency of absorbed nitrogen for grain production.

Phosphate is the key macronutrient required for the growth of plants. The soluble forms of phosphorus when applied to soil are rendered insoluble by undergoing chemical fixation. The soil collected from organic farm, SKUAST- Jammu was investigated for screening the phosphate solubilizing bacteria. In the present study, soil samples were collected from rice rhizosphere of sixteen varieties grown in OFRC, SKUAST- Jammu. This study revealed the existence of Phosphate Solublizing bacteria in the rhizosphere soils of rice.

The KVK, Mangan, North Sikkim conducted On Station Trials and Frontline Demonstrations to evaluate the suitability and profitability of high yielding rice variety Abhishek over local variety Attey as check in different locations. Improved organic cultivation practices were followed for the Abhishek variety and traditional farmer practices for the local check variety. The results indicated that the yield increase of 46.34 to 51.72 percent in Abhishek variety was recorded over local variety. Highest yield of 37.70 qt/ha with net return of Rs. 1,22,500 and C:B ratio of 2.

Global demand for organically grown foods is increasing and organic agriculture is growing fast in recent years. Organic farming encourages the reduction of agrochemicals and promotes soil conservation principles. Field experiment was conducted at Krishi Nagar, Research Farm, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (MP) during kharif season 2018. Experiment was carried out using randomized complete block design involving twelve scented and non scented rice (Oryza sativa L.) varieties with three replications. An improved scented varieties viz.

A field experiment was conducted during Rabi season of 2018 in Departmental Research Field of Department of Horticulture, SHUATS, Prayagraj on heading type of Chinese cabbage (Brassica rapa ssp. Pekinensis)/ napa cabbage. The experiment was conducted in Randomized Block Design (RBD) with ten treatments replicated thrice. The experiment consisted of Bio-char (10t/ha, 20t/ha and 30t/ha) made from rice husk and Photosynthetic bacteria, Rhodopseudomonas paulistris (66L/ha, 132L/ha and 198L/ha). The variety, All Season No. 2 was used for sowing.

Investigation into the effect of fly ash with three organic manures viz., Farm yard manure (FYM), green leaf manu) and Humic acid (HA) and inorganic fertilizers on the yield and uptake of rice was studied. The test crop was rice variety (ADT 49) Field experiment was conducted during 2014-15 in Krishi Vigyan Kendra, Tirur, Tamil Nadu Agricultural University. Fly ash generated from Mettur Thermal Power Station was selected for the study and examined for its physical and chemical properties. Analysis of fly ash revealed that it is neutral to alkaline (pH 8.1) in reaction.

Nitrogenous fertilizers applied to soil undergo various physico-chemical and biological transformations due to influence of different enzymes and microbial activity and thereby become available to crops. The efficient use of nitrogen is recognized as an important production factor for rice production but it has always been a problem to raise its utilization rate by rice and to increase efficiency of absorbed nitrogen for grain production. Even with the best agronomic practices only 30-40 percent of applied nitrogen is actually utilized by the crop.
