Florunner peanut was grown after 1 and 2 years of Tifton 9 bahiagrass, corn, cotton, and continuous peanut as whole-plots. Pesticide treatments aldicarb (3.4 kg a.i./ha), flutolanil (1.7 kg a.i./ha), aldicarb + flutolanil, and untreated (control) were sub-plots. Numbers of Meloidogyne arenaria second-stage juveniles in the soil and root-gall indices of peanut at harvest were consistently lower ...

Variable fertilization for crops, like corn, depends on monitoring nutrition condition. Thus, hyperspectral reflectance was used to predict chlorophyll and total nitrogen content under different N,K treatments during corn growth. The area of the experimental field was divided into 3 strips with different nitrogen treatment (N1:0 kg/ha–low, N2:314 kg/ha–normal, and N3:653 kg/ha–high). In each st...

Trials were started in spring, summer and autumn to compare the effect of Agrotain-treated urea and standard urea, at application rates of 25, 50, 75 and 100 kg N/ha, on dairy pasture production on a commercial dairy farm in Canterbury. There were six replicates of these eight treatments, plus two control plots per replicate where no urea was applied. Each trial was mown three times at around t...

RESUMEN The present study was carried out in a Typic Hapludand soil in the municipality of ‘El Rosal’ (Colombia) and aimed to compare the yield performance of the cultivar Criolla Colombia under foliar applications of Zn chelate (0, 1, 2 and 3 kg ha) and edaphic applications of granulated Zn sulfated (0, 1, 2 and 3 kg ha). A split-plot, randomized complete block design, with four repetitions pe...

The study was carried out for two consecutive years (2005-06 to 2006-07) to evaluate the wheat response to five different levels (0, 4, 8, 12 and 16 kg ha) of manganese (Mn) alongwith 150-100-60 kg NPK ha application. The experiment was laid out in randomized complete block design (RCBD) with three repeats under irrigated conditions at Agriculture Research Farm Karor, District Layyah. NPK was a...
