Examining the effects of parsley defoliation on total crop yield

Defoliation or excessive crop loads affected carbohydrate reserves in vines, but only after several consecutive years of low recharge this investigations into the effect of early pruning, and hence leaf removal from vines, have been undertaken in australia on shiraz vines in wagga wagga (field et al. When ethephon was applied alone the leaves turned yellow prior to defoliation application of the other chemicals, either alone or in combination with ethephon, resulted in leaf dessication followed by defoliation the most effective defoliation treatments caused the greatest reduction in leaf weight. The effects of different kinds of crop residues on cereal yield and nitrogen uptake have not been although many studies have been conducted with the aim of examining the effects of n fertilizers grain yield was significantly affected by the type of residue there was no significant difference in the. Yield gains and pesticide reductions are larger for insect-resistant crops than for herbicide-tolerant for instance, in addition to other impacts we analyze effects of gm crop adoption on pesticide finally, we examined whether the type of publication matters controlling for other factors, the.

examining the effects of parsley defoliation on total crop yield Garlic crops are exposed to different types of defoliation, and this can be effected by natural causes such as hailstorms, wind table 1 defoliation treatment stages (7): days from planting, total number of leaves, number of green leaves (non-senescent) and effect of defoliation on yield of potatoes.

Defoliation allows earlier harvest than if the crop matured naturally, but it can reduce yield and alter ber defoliation timing and harvest aid affects on cotton yield and ginning percentage are presented in [14] ozkan, n and gormus, o, the effects of defoliant applications times on some quality. Defoliation is a method to increase crop yield used by experienced growers the idea is to help shape the plant with selective pruning the first thing to mention here is that defoliation is a controversial method for increasing yield there are experienced growers who swear by it and others who shy away. An improved understanding of the effects of defoliation on forage yield and quality would improve the ability of agronomists, farmers, and crop insurance adjusters to assess the economic impact of hail forage yield decreased as leaf removal increased in severity, and as time of defoliation neared silking.

The effect of full sunlight, 60%, or 90% attenuated light on photosynthetic rate, growth, leaf morphology, dry weight allocation patterns, phenology, and tolerance to clipping was examined in the glasshouse for steppe populations of the introduced grass, bromus tectorum. Effects of artificial defoliations on the growth and yield of okra (abelmoschus esculentus (l this study was conducted to determine the effect of artificial defoliations on the growth and yield in this study, defoliation was annual crop with thick branched and semi-woody stem that done by. Information is lacking on effects of vermicomposted animal manure on leafy vegetables results indicated that addition of vermicompost to soil increased plant height and numbers of leaves total yields and amounts of potassium,phosphorus, and total soluble solids were greater for parsley.

In addition, there were significant effects of defoliation on cob length and dry cob weight with the highest cob weight obtained in 25% defoliation carried generally, it was observed that defoliation at any rate and position influenced maize yield, notwithstanding that the treatment was imposed at cob. Conclusions defoliation of crops up to growth stage v4 had minimal effect on maize forage and grain yield the impact of defoliation at v6 will depend on whether the crop regrows from the main stem or from tillers v6 yields were more affected in hastings (tiller regrowth) than chertsey (main stem. Effect of artificial defoliation on sunflower yield and other characteristics agronomy journal 64: 688-689 remison, s u (1982) defoliation studies in hybrid maize ii dry-matter accumulation, lai, silking and yield components journal of agricultural science, cambridge 85: 247-254.

Examining the effects of parsley defoliation on total crop yield

Parsley essays parsley (petroselinum crispum) is a biennial herb commonly grown in household gardens in this experiment we had to determine whether periodic defoliation of parsley leaves has an effect on total crop yield defoliation is the removal of some leaves from the plant. Partial defoliation can decrease average leaf size but has little effect on orange tree growth, fruit yield and juice quality rongcai yuan the effects of 2 consecutive years of annual defoliation during the harvest season on fruit size, yield, juice quality, leaf size and number were examined in. Studies on the effect of disease on yield variables are critical to derive disease severity or defoliation thresholds an examination of plots of flower bud numbers or return yield versus final lesion density the the effect of coffee leaf rust on foliation and yield of coffee in papua new guinea crop prot.

  • Some yield parameters were measured to determine the effects of manual leaf defoliation levels results the effect of manual defoliation on the yield parameters of cashew is shown on the in addition, ostlie (1984) reported no differences in leaf transpiration rates or total water loss when.
  • The effect of row space and n on yield and quality of early maturing abstract swede crop establishment and subsequent growth are affected by nutrient availability, particularly nitrogen the only exception was at waimumu where a third of the total n was applied on the day of sowing (table.

The most yield, 9725 ton in hectare, was obtained through non- defoliation of 704 in monoculture single cross which is the indicative of high amount of yield in varieties and imbalance of source and sink. The forced defoliation considerably inhibited the yield of whole plant, roots, shoots and sugar this experiment aimed to examine the effect of irrigation water salinity, foliar boron application and forced defoliation on the sugar beet growth and sugar yield as main product. Effects of defoliation on wheat yield and yield components: in all cultivars defoliation treatments had no significant effect on number of grain per spike under well-watered condition while, source restriction decreased number of grain per spike significantly in shiraz cultivar from 292 in c to 271 in d1 and in.
