hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” agrobacterium rhizogenes. in most plants such as cichorium intybus l., hairy root cultures have proven to be an efficient system for secondary metabolites production. the effect of zinc (znso4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mm) on some secondary metaboli...

La eficiencia del uso nitrógeno (EUN) por los cultivos agrícolas es muy baja pérdidas asociadas con su alta solubilidad y, en algunas condiciones de suelo, volatilidad, lo que trae como consecuencia impactos negativos la rentabilidad económica y contaminación medio ambiente. Se realizó un experimento campo bajo riego suelo Bajío Guanajuato, México para estudiar asimilación fertilizante nitrogen...

In laboratory studies performed in the United States and Hungary, the dump fly Hydrotaea aenescens (Wiedemann) was reared successfully in manure of 1- to 8-wk-old dairy calves, and in manure from adult lactating dairy cows. Survival in manure collected from 1-wk-old calves was poor (7.2%), better in manure collected from 2- and 3-wk-old calves (53.5%), and best in manure collected from 4- to 8-...

The Field experiment was conducted at College farm, of Agriculture, Rajendranagar, Hyderabad during rabi season 2022 on zinc deficient soils to evaluate the effect nano growth, yield and quality sweet corn. study included 9 treatments with 3 forms Zn fertilizer viz., ZnSO4, EDTA Nano Zn. Results indicated that foliar application 5 g L-1 produced significantly highest parameters, cob (15.5 t ha-...

A microplot study was conducted on a medium black soil to screen improved sulphur (S) utilizers among blackgram genotypes. For this experiment, four different S sources including Gypsum, SSP, FeSO4, and ZnSO4, were applied at levels (S @ 0, 20, 30, 40 kg ha-1). With the application of high (40 ha-1), growthand yield parameters (plant height, root length number pods per plant) gram increased sig...
