Abstract

Humic acids are highly stable and functionalized portions of soil organic matter. Because of it’sstructural heterogeneity and surface porosity, it act as a catalyst in soil nutrient enrichment and palnt growth. Besides, humic acid sequestrate the heavy metal ions on it’ssurfaces by pore filling and multilayer adsorption. The study focused the structural behavior and the physico-chemical properties of the humci acid extracted from the laterite soils of Kannur district of Kerala. And evaluated the sorption performance of the humic acid with cadmium ion. Efficacy of the removal of the cadmium ion by humic acid will leads to an green technology for water purification and the sustainable use of the natural resources.

Abstract

The agricultural sector is in a dramatic situation in Moldova, a family-based economy.

The recent situation created by the rising cost of non-renewable energy sources and their derivatives makes it necessary to re-examine the way of doing agriculture in Moldova. It is time to move quickly to the bio-dynamic model of agriculture. Agricultural producers group improve the loan exchange of inputs and machinery, help improve education, reduce family poverty and information redundancy due to the creation of a mutual knowledge base and a high level of trust between members. Providing a new perspective to the existing literature, this paper presents a Culture-Knowledge-Intelligence-CKI model that explains the impact of culture on knowledge and intelligence. The study concludes that culture change is necessary to farmers be open to learn modern agricultural practices and business language.

Abstract

The field experiment was conducted in Rabi season during November 2021-March 2022 to find out the effect of organic and inorganic manure on growth and yield of Chickpea (Cicer arietinum L.)at research field of College of Forestry, SHUATS, Prayagraj, UP. The experiment is laid out in Randomized Block Design (RBD) consisting of 9 treatments replicated thrice. Various treatments. Result revealed that at 30 DAS interval maximum plant height (19.44cm), at 60 DAS interval maximum plant height (50.65cm), at 90 DAS interval maximum plant height (56.51cm), at 30 DAS maximum number of branch (4.73), at 60 DAS maximum number of highest number of branch (9.87) and at 90 DAS maximum number of branches (12.27), at 70 DAS the highest 50% flowering% (77.87), at 70 DAS highest number of pods per plant (no.) (41.13), at 70 DAS the highest number of seeds per pod (no.) (2.73), after harvesting the highest test weight (100 seed, hundred-seed weight) (gm) (31.33), after harvesting highest grain yieldq/ha (20.67). after harvesting highest straw yieldq/ha (19.33), after harvesting the highest harvest index % (48.67) and maximum benefit cost ratio 1:70. While maximum gross return (121847.5) and maximum net return (76,828). The highest recorded in the Treatment T9 (NPK 100% + FYM 100%).
