OBJECT Improved precision fertilization by introducing sensors and remote control to secure fruit yield and reduce nutrient leaching in soil culture. MATERIAL AND METHODS We broadcasted before bedding and mulching 50 g m-2 of a multi-mineral fertilizer. Beds had two plant rows 20 cm apart, with plant distance of 25 cm. Experimental design was split plot with three replications and three treat...

Chemical plant growth regulators (PGRs) are used in the production of ornamental potted and bedding plants. Growth control is needed for maximizing production per unit area, reducing transportation costs and to obtain a desired visual quality. However, the use of PGRs is associated with toxicity risks to humans and the environment. In many countries the availability of PGRs is restricted as few...

The proficient supply of water and nutrients is a key factor for successful vegetable production under greenhouses. This field experiment was conducted during 2018–2019 completely randomized design to evaluate the effects drip irrigation nutrient schedule on soil dynamics productivity greenhouse tomato. consisted two schedules, i.e., I1 (irrigation applied from week 1 2 basis 100% pan evaporati...

The litter carbon (C) pool of a single litter cohort in an agroecosystem is the difference between net primary productivity and decomposition and comprises 1113% of the total C pool (litter and soil 0-15 cm depth) post-harvest. This litter-C pool is highly dynamic and up to 50% can be decomposed in the first 12 months of decomposition. Thus, understanding litter-C dynamics is key in understandi...

irrigation management, soil tillage method and fertilizer management play important roles in increasing crop yield and water and solute movement in the soil profile. the present research was conducted to study the effects of a no-tillage system and nitrogen fertilizer on the mineral nitrogen movement and soil moisture under optimum irrigation conditions. the study was conducted at safiabad agri...

introduction: broadcast fertilization method increases fertilizer losses while results in lower nutrient absorption by plant roots. fertigation is an effective method to increase water and fertilizer efficiency and to reduce the losses of nitrogen. moreover, it allows farmers to apply the nutrients in splits and few amounts in response to crop needs. in the present study, a field experiment was...
