Sesame (Sesamum indicum L.) is one of the chief foreign exchange earning oil crops in Ethiopia. However, its productivity remains low due to lack of appropriate agronomic practices. The aim of this research was to study the effect of organic mulches on sesame productivity and in situ moisture conservation. This experiment was carried out in Humera Agricultural Research Center, Western Tigray, during 2015 growing season. The experimental design was Randomized Complete Block Design with three replications. There were four types of organic mulches; rice straw, sorghum straw, sesame straw, and Sudan grass were compared with control. Sesame, variety Setit-1 was used in the experiment. The organic mulching rate of application was 10 ton ha−1and this was applied evenly to the soil immediately after germination. Soil water content, phonological characteristics yield, and yield components of sesame were collected. The analyzed results indicated that organic mulching had significant effect on soil moisture content at 0–0.2 m, 0.21–0.4 m, and 0.41–0.6 m in every two-week interval after sowing and grain yield of sesame. Sesame straw conserved highest soil moisture content as compared with respective mulch material. The highest yield (664 kg ha−1) was recorded with Sudan grass while the lowest grain yield (190 kg ha−1) was recorded with no mulch.

Draft requirements of two animal – drawn (IAR) weeders operating on loam soil were determined in the study. The implements include a straddle row weeder and an emcot attached rotary weeder evaluated under the same soil conditions, using a pair of white Fulani breed of oxen. The animal draft requirement was first estimated from the animal ergonomics measurements. Using area of 0.054 hectare as experimental plot for each implement the draft requirement of each implement was investigated after taking soil samples for soil moisture content and bulk density determinations. The implements tested showed variation in their average draft requirement. The straddle row weeder had the highest value of 338.15 N respectively while the emcot attached rotary weeder had the lowest value of 188.12 N with 47.03%, respectively. The average soil moisture contents and bulk density were 13.0% and 1.46%/cm3, respectively.

Poor and uneven emergence of seedlings decreases the efficiency of sesame (Sesamum indicum) seed production. In a glasshouse study, seedling emergence was reduced by low soil moisture content (less than 20%, w/v) and by waterlogging (common in soils with small soil particles). Watering events that failed to raise soil moisture content above 20% caused most seeds to germinate (more than than 80%), but only some of these seeds emerged from the soil (less than 50%). Gibberellic acid pre-treatment of seeds (50 or 1000 mg/L) failed to improve emergence of seeds from soils with an initial soil moisture content less than 20%. This result supports previous reports suggesting that gibberellic acid treatment does not influence seedling emergence, and may only be useful to overcome seed dormancy in those sesame varieties where dormancy is a problem. For maximum emergence it is recommended that sesame seeds be sown in non-waterlogged soils and that soil moisture content be maintained above 20% for a number of days after sowing.

Watermelon (Citrullus lanatus) production is concentrated in southern Florida where growers often use seepage irrigation. According to a recent survey, growers believe that nitrogen (N), phosphorus (P), and potassium (K) rates recommended by the University of Florida Institute of Food and Agricultural Sciences (UF-IFAS) are low. A study was conducted during Spring 2004 and 2005 at a UF-IFAS research farm to compare three nutrient and water management systems: high rate [HR (265, 74, and 381 lb/acre N, P, and K, respectively)], recommended rate [RR (150, 44, and 125 lb/acre N, P, and K, respectively)], and recommended rate with subsurface irrigation (RR-S). Irrigation was managed to keep soil moisture content at 16% to 20% for HR and 8% to 12% for RR and RR-S. The experimental design was a randomized complete block design with two replications and three subsample areas within each 0.25-acre plot. The HR management approach produced ≈60% to 80% higher yields (cwt/acre) during 2005 than RR or RR-S. The HR treatment produced larger watermelons than RR or RR-S in 2005. Triploid watermelon prices had to be at least $3.74/cwt to cover all costs associated with HR. The HR approach increased the grower net returns by $590/acre and $1764/acre under conservative and higher yield and price expectations, respectively. Soluble solids content and hollowheart ratings were unaffected by treatment. Total biomass, recorded during 2005, followed a similar trend as yield, with HR producing 105% and 125% greater total dry weight than RR and RR-S, respectively. Total N content of HR biomass was 56% higher than that of RR and RR-S. Total P content was 29% and 50% higher than that of RR and RR-S, respectively. Leaf and petiole tissue from the HR treatment exhibited consistently higher N and K leaf tissue values during 2005 than RR and RR-S. In conclusion, trends in the data consistently showed greater plant performance with higher rates of fertilizer and soil moisture content. Our ability to detect differences in 2005 was probably enhanced by higher rainfall during 2005 compared with 2004.

An experiment was carried out at the Bangladesh Agricultural University Farm, Mymensingh during the Aman season of 2008 to study the effect of tillage intensity, fertilizer and manure on the root mass density soil properties and their correlation on rice yield (BRRI dhan 41). The experiment was laid out in a split plot design with three replications. The treatments were three tillage operations as factor A: one passing (P1), two passing (P2), and three passing (P3) of a power tiller and four fertilizer and manure treatments as factor B: recommended dose of fertilizers (FM0), 50% of N plus rest of recommended dose of fertilizers + cowdung @ 5 t/ha (FM1), 50% of N plus rest of recommended dose of fertilizers + rice straw @ 5 t/ha (FM2) and 50% of N plus rest of recommended dose of fertilizer + cowdung @ 2.5 t/ha plus rice straw @ 2.5 t/ha (FM3). The highest and the lowest bulk densities were found in P1FM0 and P3FM treatments, respectively. The maximum soil moisture content and air filled porosity were obtained in P3FM1 treatment, whereas PM1FM0 demonstrated the lowest soil moisture content. The maximum (8.09 mg cm-3) and minimum (1.63 mg cm-3) root mass densities were observed in P3 (10 cm depth) and P1 (10-20 cm depth) treatments, respectively. The highest grain yield was recorded in P3FM0 treatment. Root mass density was positively correlated with soil moisture content and grain yield, but negatively with bulk density. Bangladesh J. Agril.

An experiment was undertaken to identify the suitable mulch paper for different high value vegetables during the winter season of November 2019 to March 2020 at the research farm of Olericulture Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh. The experiment was randomized complete block design with 3 replications. Three vegetables varieties viz., netted melon, watermelon, cucumber and 3 mulch treatments viz., T1=Silver over black mulch; T2= Black mulch; T3= No mulch were included in this study. Different vegetables responded differently with the changes of mulches irrespective of different characters. Considering relationship between the soil moisture content and fruit number it was clear that fruit number, average fruit weight, fruit length, fruit diameter was strongly related with soil moisture content. The effect of different plastic mulches on fruit weight per plant and yield (t/ha) were significant. Mulching produced higher fruit yield per plant and fruit yield per hectare than for the control, indicating that the mulch had positive effect in generating increased fruit yield. Silver over black plastic mulch produced the highest fruit yield viz., 24.22 t/ha (cucumber), 26.37 t/ha (netted melon), 43.59 t/ha (watermelon) followed by black and no mulches. Obviously, control plot produced the lowest fruit yield.

Post anthesis drought is common problem in late sown wheat, which reduces crop yield. A field experiment was conducted at Institute of Agriculture and Animal Science (IAAS), Rampur in 2005/06 to find out the effect of irrigation, seed rate and mulch on soil moisture content and productivity of late sown wheat. Irrigation applied at crown root initiation CRI and heading stage significantly increased moisture content at 80 days after sowing, grain filling period (GFP) and crop duration period (CDP), thousand grain weight, grain yield and harvest index. Higher seed rate was non significant on yield attributes and yield. Soil moisture content at 30, 80 and 95 days after sowing, vegetative growth period (VGP) and crop duration period, and grain yield were significantly higher in mulched plot than non mulched plot. Irrigation at reproductive stage and mulch were effective in increasing yield of late sown wheat.

The Effect of Soil Tillages Frequency and Compost Fertilizer on Soil Physical Properties and Corn Yields. The aims of this research is to determine of effect soil tillage frequency and compost fertilizer on soil physical properties and corn yields. The method was used a Randomized Block Design (RBD), factorial consisting of two factors, namely: Soil Tillages Frequency (T) consists of 3 levels, namely: T0 = no tillage; T1 = if one time and T2 = if twice. Compost Fertilizer (K) consists of 3 levels, namely: K0 = Without compost, K1 = 5 tons compost/ha and B2 = 10 tons compost/ha. Combination treatment into 9 treatments, namely T0K0 , T0K1, T0K2, T1K0, T1K1, T1K2, T2K0, T2K1, T2K2. and each treatment was repeated 3 times, so there were 27 research plots.The results showed that the soil tillage frequency and compost fertilizer had no significant effect on the soil physical properties and corn yields. Twice soil tillage frequency resulted bulk density, porosity, soil moisture content and dry corn yields respectively 1.01 g/cm3, 60.98%, 37.31% and 0.83 kg/m2, and not significant different compared with no tillage which is 1.03 g/cm3, 60.43%, 36.57% and 0.81 kg/m2. Addition of 10 tons compost/ha resulted bulk density, porosity, soil moisture content and dry corn yield respectively 0.99 g/cm3, 61.75%, 38.21% and 0.86 kg/m2, and not significant different compared with without compost fertilizer which is 1.06 g/cm3, 59.40%, 36.44% and 0.80 kg/m2.

A reliable and low cost sensor that can measure soil moisture at or near the soil surface is currently not available. The objectives of this study were: (i) to evaluate the possibility of modifying an impedance probe (IP) to measure soil moisture content at a very shallow depth (2–5 cm); and (ii) to compare the soil moisture values obtained using the IP to the values obtained using the traditional gravimetric method. The research was conducted at the Winfred A. Thomas Agricultural Research Station (WTARS) Hazel Green, Alabama. The standard IP that is capable of measuring soil moisture content at 6-cm soil depth was modified to measure soil moisture at 2-, 3-, and 5-cm depths. Using a site and depth-specific calibration technique it provided results that were comparable to the values that were obtained following the traditional gravimetric water content determination protocol. We found that the instrument was very sensitive to changes in soil moisture content and has great potential as a replacement for the gravimetric technique. It allows repetitive measurements of soil moisture content at a very shallow depth with minimal soil disturbance. Fur thermore, the instrument is particularly valuable for providing ground- truth soil moisture contents to validate remotely sensed data. Key words: Soil moisture, remote sensing, impedance probe, ground-truth, validation
