Field capacity (FC) and permanent wilting point (PWP) are important factors affecting irrigation scheduling and field management. FC and PWP can be estimated from some of the soil physical and chemical properties. Pressure Plate apparatus is usually used for determination of FC and PWP, but this is a time-consuming and laborious procedure besides, the apparatus may not be available in many labo...
Replenishing nutrients through organic sources is essential to maintain the soil health and sustainability in Eastern Himalayan Region, India which is organic by default. Keeping this in mind an experiment was laid out on randomized block design with six treatments viz., T1: Vermicompost (VC; 2.5 Mg ha-1), T2: Poultry manure (PM; 1.25 Mg ha-1), T3: Swine manure (SM; 3.0 Mg ha-1), T4: Cow du...
Field capacity and permasent wilting point are the most important parameters in designing and programming irrigation, whose measurements are troublesome and time-consuming. But these parameters could be estimated by easy data characteristics such as soil texture, organic matter and gypsum, using Pedotransfer Functions (PTFs) with high precision. In order to estimate soil moisture at FC and PWP ...
The effect of four different levels of irrigation periods, including normal irrigation, irrigation after 100, 150, and 200mm evaporation, with three different bio-fertilizer including control, Mycorrhiza, and Rhizobium were investigated on morphological and yield traits of guar. The experiment was conduct in form of split-plot design with irrigation periods as main plots and bio-fertilizers as ...
Robust assessment of crop water availability requires effective integration soil moisture data within the range field capacity (θFC) to permanent wilting point (θPWP). Emerging needs for spatiotemporally dynamic θFC and θPWP are difficult achieve with lab determinations. Therefore, we used long-term from 182 sites across United States evaluate whether extremes defined by 95th 5th percentiles re...
Rice production in East Java has decreased, which is related to climate change. Uncertain results a shift planting time. Climate projection scenarios are solution see future climatic conditions. One of the analyses used water balance. This study aims balance determine rice (Oryza sativa L.) time based on scenarios. The research was conducted from March July 2022 four districts Java. materials a...
