Management of micronutrients require special attention in orchard soils as the requirement of micronutrients for nutrition, physiological need and quality control is more in fruit crops. Distribution and variability of micronutrients in the soil and leaf of litchi orchards of Kangra district of Himachal Pradesh was studied. For this, forty soil sam...

Soil analysis is commonly used to gauge its quality and suitability for diverse purposes from local to national evaluations. However, the complexity of soils, their site-specific traits, past land use impacts, and balancing ecosystem benefits pose significant challenges in identifying relevant parameters and interpreting measurements. This manuscri...

Globally, the majority of farmers use various cropping systems. In order to increase the production of food grains, the adaptation of these cropping systems necessitates intensive cultivation, which eventually calls for a greater quantity of macronutrients as well as micronutrients. The availability of micronutrients is greatly influenced by croppi...

The investigation was undertaken and micro nutrients status of the area was assessed. During February-March 2020, 50 soil sampling locations from tomato growing areas were selected at random and 100 representative surface (0-15 cm) and sub-surface (15-30 cm) soil samples were collected. Various micronutrients, i.e. DTPA-extractable Zn, Cu, Mn and F...

A field experiment was conducted at the experimental site of Department of Soil Science and Water Management, College of Horticulture and Forestry, Neri, Hamirpur (Himachal Pradesh). The experiment consisted of eleven treatments which were carried out in randomized block design with three replications. Observations for micronutrient uptake and soil...

An experiment was conducted at the Experimental farm of Department of Soil Science and Water Management, Neri, Hamirpur to study the combined effect of organic, inorganic and biofertilizer on soil properties. The experiment was laid out in a Randomized Block Design with three replications and consisted of 11 nutrient managements viz., control (T1),...

Imbalanced fertilizer use with intensive cropping has threatened the sustainability of agroecosystems, especially on acid soils. An understanding of the long‐term effects of fertilizers and amendments on soil health is essential for sustaining high crop yields. The effects of application of fertilizers, and amendments for 46 years on soil propertie...

Nutrient management in the subtropical fruit production is very important for obtaining high quality fruits. It involves using crop nutrients as efficiently as possible to improve productivity while protecting the environment. The key principle behind nutrient management is balancing soil nutrient inputs with crop requirements. A well-nourished fru...

Present-day agriculture is challenged to fulfill with twin objectives of achieving food, fodder, fiber and fuel security as well as restoring soil resources for long-term use. Efficient use of crop residues and other farm wastes by converting them to a useful source of soil amendment is a beneficial way to improve soil fertility. The biochar amendm...

Heavy metals, peculiarly copper (Cu), nickel (Ni), cadmium (Cd), zinc (Zn), chromium (Cr), and lead (Pb), are regarded as one of the major sources of pollution of agricultural soil which result in heavy metals accumulation in plants and successive addition along the food chain. The intake of food contaminated with heavy metals by humans can diminis...

This study was undertaken in an on-going long-term fertilizer experiment, initiated during 1972-73 at Experimental Farm of Department of Soil Science, CSK HPKV Palampur to work out the relationship of soil health parameters with quality of maize in an acid Alfisol. The soil of the experimental site was silt loam and classified taxonomically as Typi...

The present study on the long-term effect of fertilizers, farmyard manure and lime on changes in soil properties and wheat productivity was carried out at Himchal Pradesh Agricultural University, Palampur (India). The soil was acidic in reaction and classified taxonomically as Typic Hapludalf. Soil samples, collected from two depths viz., 0–0.15 m...

Impact of integrated nutrient management was assessed on crop yields and soil properties under pea-okra system. Thirteen treatments combinations of lime, NPK doses and vermicompost were imposed in pea-okra cropping system from rabi 2008-09 to kharif 2011. The recommended doses in 100 % N, P and K were 50:11:42 and 75:21:42 for pea and okra, respect...

Effect of long-term addition of chemical fertilizers with or without amendments was studied on different forms of potassium and the yield of maize and wheat. Continuous application of chemical fertilizers and amendments for 40 years influenced different fractions of potassium significantly. Integrated use of a balanced dose of chemical fertilizer,...

The present investigation was undertaken in the on-going long-term fertilizer experiment initiated during 1972 at experimental farm of Department of Soil Science, Himachal Pradesh Agricultural University, Palampur, India. Continuous application of fertilizers either alone or in combination with farmyard manure (FYM)/lime affected different forms of...

A study on long-term effect of fertilizers and amendments on crop productivity and changes in soil fertility in maize-wheat cropping system in an acid Alfisol was carried out in randomized block design with 11 treatments. Continuous application of chemical fertilizers along with farmyard manure (FYM) or lime significantly influenced the grain and s...

The present investigation was undertaken to study the effect of integrated nutrient management on yield and quality of pea (Pisum sativum L.) in an acid Alfisol of Himachal Pradesh using cv. Palam Priya under irrigated conditions at the experiment farm of the Department of Soil Science, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur during r...

The present investigation was carried out to study the effect of integrated nutrient supply on forms of aluminum and acidity at the Experimental Farm of Department of Soil Science, COA, CSK HPKV, Palampur in a randomized block design with 13 treatments replicated three times. The soil of the experimental site was silty clay loam and classified taxo...

In a field experiment initiated in 1991 kharif season (April–October) on an acidic soil in the Western Himalayas of India, 25% and 50% of the recommended doses of nitrogen were substituted through different organics, viz. farmyard manure (FYM), wheat cut straw and Sesbania aculeata (as green manure) in rice, followed by use of chemical fertilizers...

Effect of long-term addition of chemical fertilizers alone or in conjunction with organics was studied on different forms of potassium in soil and their relationship with rice yield and K uptake. Continuous addition of chemical fertilizers along with different organics improved all the potassium fractions in soil over control. Integrated use of che...

Effect of nitrogen substitution through different organics on yield, uptake and available nutrients in a rice- wheat system was studied after 17 and 18th cropping cycles. Nitrogen substitution through different organics increased significantly the productivity and NPK uptake by rice and wheat. Grain yield of rice, wheat and that of the system incre...

Impact of integrated nutrient management was assessed on crop yields and soil properties under long-term experiment. Ten treatments comprising of control, inorganics viz., 50, 75 and 100% NPK and conjoint use of 50 and 75 % NPK with 50 and 25% N substitution either through FYM, wheat cut straw or green manure, Dhaincha (Sesbania aculeata) during kh...

The role of water has been well recognised to sustain life for plants, animals and humans. Land and water are the two basic important natural resources, which play an important role in agriculture production.The plants must be provided with sufficient water for its existence as well as the growth. The water, air, and the sunlight are the main requi...
