VALIDATION AND REFINEMENT OF SOIL TEST BASED DERIEVED FERTILIZER EQUATION FOR SRI RICE IN VERTISOL

Field experiments were conducted during 2015-16 to gauge the fertilizer requirements for hybrid rice (cv. US-382) under Integrated Plant Nutrient Supply in Alluvial soils of Jorhat district of Assam. Following Ramamoorthy’s Inductive cum targeted yield model, the nutrient requirement per quintal of[r]

Most of the farmers with extensive poverty in Surguja dominated by rainfed ecologies where rice is the principal source of staple food, employment, and income for the rural population. Success has been limited in increasing productivity in rainfed rice systems. The study based on primary as well as[r]

Conservation agriculture (CA) is based on principles of minimum soil disturbance through zero or minimum tillage operations, residue retention on soil surface and crop diversification which not only improves healthy functioning of soil but also enhances nutrient availability, its biological quality[r]

Agricultural growth with stability has been a matter of concern in Odisha. As rice is the major crop growing in the state, the present study was therefore carried out with the objectives to work out the district wise growth rate of area, production and yield of rice and to estimate district wise ins[r]

A pot culture experiment was conducted in earthen pots contains 5 kg of well mixed air dried red sandy loam soil. The rice var. BPT 5204 used as test crop. Carefully selected uniform sized seeds were directly sowed in each pot.

The present investigation entitled “Genetic variability, heritability and genetic advance in rice (Oryza sativa L.) under salt affected soil” comprised of 7 lines and 3 testers recommended for sodic soil. Crosses were made in “line x tester mating design. Thus 21 crosses (F1‟s) were produced during[r]

Among the various Sub-catchments in the state of Jammu and Kashmir, the Namblan Subcatchment of Jhelum basin has not been studied in view of the nutrient status of the soils. Based on variations in vegetation, altitude, land use and soil heterogeneity six representative soil profiles were exposed an[r]

The current investigation was performed with two major objectives: Assessment of BPH resistance of the batch of converged rice cultivars and local rice varieties; Phylogenetic analysis and using marker molecular-based breeding methods to develop the excellent 2-3 cultivars with sustained resistance[r]

The largest producer is Africa, Brazil, Haiti, India, Myanmar, Srilanka, Australia; Bosnia and Herzegovina also have significant production. Worldwide cowpeas are cultivated in approximate 8 million hectares. The total world production is estimated about 3.3[r]

A study was under taken to assess the available (DTPA-extractable) zinc and iron in soils under rice based cropping system in Chamarajanagar district, Karnataka, India. Results of the study indicated that the soils were sandy clay loam in texture with neutral to alkaline pH (6.6 to 9.2).

The recommended dose of fertilizer for cowpea is 25:50 NP kg ha-1 . Farmers does not follow the recommended dose of fertilizer, they are using low fertilizer level and soil fertility status has deteriorated over the years which resulted in low productivity.

In this respect, soil FDA is an important indicator of soil microbial activity and biological health of soil. The aim of this research was to assess the effects of crop residue retention and P fertilization on FDA activity in soil.
