Yield growing conditions

Differences in opium yield between Afghanistan and Myanmar are due to differences in opium poppy varieties and growing conditions. Variations of yields from year to year in the same country are mostly caused by changes in weather conditions and/or, as in the case of Afghanistan in 2001, by a shift in the relative distribution of cultivation from irrigated to rain-fed land. 

This crop appears to be generally more winter-hardy than soft red winter wheat, but less winter-hardy than hard red winter wheat. The yield is generally lower than that of wheat but equal to wheat when the growing conditions are less than ideal. 

Table 1 is important to the analysis of SSPs because it establishes a basis for future evaluation of the fuel source. Yet, much of the information is subject to growing conditions such as soil, water, and amount of competition with other plants. Because there are no cultivated acres of these plants, the projected yields listed in Table 1 are based on stalk weights, which were measured, and growth density (stalks/m2), which were estimated. The estimations came from grid layouts made in productive parcels of wild-grown fields. They represent what I feel to be a conservative estimate of what densities can be achieved in cultivation. 

Jerusalem artichoke thrives under a wide range of growing conditions. However, yields can be greatly affected by environmental factors, including solar radiation, temperature, length of the growing season, and rainfall. 

Chia seed contains 25 0% oil and 18-30% protein. The chia meal is high in protein and fiber similar to flaxseed and soybean (52, 53). Chia seed, oil, and meal can be used as ingredients with high nutritional value for human food and animal feed. Chia seed contains mucilage and water-soluble fiber, may possibly contain lignans, and is similar to flax (53). Trials conducted in 1995 and 1996 showed yield and oil contents to be affected by growing conditions and harvested yields were up to 1500 kg/ha (52). 

The approximate chemical composition of olive fruit is as follows water 52.4% oil 19.6% proteins 1.6% sugars 19.1% cellulose 6.8% and ash 1.5%. Oil yield and quality depend on the cultivar of olive tree, ratio of the various anatomical parts, and levels of minor components as well as growing conditions and health of the trees. Soil moisture is very important during fruit development. 

It was shown that most microorganisms yield characteristic pryolysis products, the pyrograms being readily reproducible under standard culture growing conditions [202— 204]. This enables the chromatograms obtained to be compared with those of known... 

The biennial form of B. campestris is also grown and although it is more winter hardy and requires a shorter growing season than B. napus, the yield of seed and oil is less under favorable growing conditions. Consequently, the area of winter 6. campestris production is limited to the more rigorous climates of central Sweden and Finland (Loof, 1972). In general, the winter forms of both species are less winter hardy than winter barley thus, their distribution is restricted to maritime climates in the temperate zones.
