Maize is globally the top-ranking cereal in potential grain productivity. It is cultivated in subtropical
regions of the world. Maize (Zea Mays L.) is the third most important food grains
crop in India after rice and wheat. In India maize produced 31.51 million tonnes in an area of
9.9 million hectares during 2020-21, (Acharya et al. 2021). In Jammu and Kashmir maizewheat
is the most prevalent cropping sequence being practiced by farming community in the
kandi belt of Jammu Division (under rainfed conditions). About 12% of the total area of
Jammu region constituting dry semi-hilly belt is rainfed in nature, the most stressed
ecosystem of this region and is locally known as kandi area. Continues use of chemical
fertilizers resulted in decline of soil physical and chemical properties and crop yield and
significant land problems, such as soil degradation due to over exploitation of land and soil
pollution caused by high application rates of fertilizers and pesticide application. Application
of Effect of organic sources of nutrient on yield and soil properties of Soybeans besides
supplying N, P and K also make unavailable sources of elemental nitrogen, bound
phosphates, micronutrients, and decomposed plant residues into an available form to facilitate
to plant to absorb the nutrients. Application of organic sources of nutrients viz FYM and
Crop residue has capability to improve soil quality and higher crop productivity in
sustainable manner without deteriorating the soil and other natural resources. Keeping the
above facts into consideration, the problem entitled “Effect of organic and inorganic nutrient
management practices on growth and yield of maize under sub-tropical kandi area Jammu
region” is proposed to identify the best type of available organic resources which can be used
as fertilizers and their best combination with appropriate proportion of inorganic fertilizers.
Methodology
A field experiment was conducted under rainfed condition during kharif season of 2019 -
2020 at Research farm of Advanced Centre for Rainfed Agriculture Rakh-Dhiansar of
SKUAST-Jammu (32° 39” N 74° 53” E 332 m amsl), under rainfed condition. The soil of
experimental site was sandy loam in texture, with a pH 6.5, low in organic carbon (0.18), and
