Intensive tillage, removal or burning of crop residues, limited organic manure use, declining irrigation water resources are the major causes of soil degradation and unsustainability of rice (Oryza sativa L.)-wheat (Triticum aestivum L.) system (RWS) in South Asia. Present investigation on “Short-term effects of conservation agriculture practices on soil quality un...

Silicon (Si) is a beneficial element which influences the growth, development and yield of many crop plants especially rice. Rice is known as silicon accumulating plant because of its high requirement which contains Si at levels up to 10 % of dry matter weight. Since optimum crop production depends on the maintenance of adequate plant nutrients in the soil, there i...

Twenty four soil profiles were exposed and four soil samples from each depth at 0-15, 15-30, 30-60 and 60-100 cm were collected from mango, guava and ber orchards falling in the sub-tropical zone of Jammu region. Besides leaf samples at flowering stage in case of mango, middle of shoots (September) in case of guava and tertiary shoots two months after pruning in ca...

Dynamics of soil aggregation and SOC and its quality are strongly influenced by land use pattern, soil erosion and land degradation. An investigation was carried out to study soil erodibility, aggregation, organic carbon stocks and organic carbon pools in different size fractions of soil aggregates and relationship among soil properties and erodibility indices as ...

A study was carried out for two maize growing seasons in the kandi region of Jammu division to gauge and measure the influence of various conservation agricultural (CA) practices on seasonal runoff, soil erosion, soil carbon sequestration, aggregate stability and yield of maize. Three tillage variations i.e. conventional tillage (CA), minimum tillage (MT) and zero ...

A study was conducted to assess the impact of different organic manures on soil properties and growth parameters in okra-broccoli cropping sequence. Study area lies in between 32°39'35.5"N latitude and 74°47'35.0"E longitude at an elevation of 332 meters above the mean sea level in the Shivalik foothill plains of North-Western Himalayas. Surface soil sampling from ...

Available zinc (Zn) being an important micronutrient in the rice-wheat cropping system the study was carried out in Kathua, Samba and Jammu districts, to observe and understand the behavior of Zn in soil which included distribution, fractionation, Langmuir adsorption characteristics, critical limit of Zn for basmati rice (cv. Basmati 370) and the effect of Zn on so...
