“application of ZnSO4.7H2O and Na2B4o7.10H2O on Zn and B deficient soils could increase balsam pear yield and its contents of protein, Vc and 17 sorts of amino acids, especially the contents of essential amino acids for human body, but decrease the NO3(-)-N content”

“There was a significant positive correlation between MDA and ABA, but a significant negative correlation with PAs, Put, Spd, Spm, IAA, GA3, ASA, SOD, POD, and CAT”
“classifying the rice plants which grown under several cultural conditions”
e2
“The percentage of ripened grains showed a tendency to decrease progressively with an increase in the number of spikelets per unit area, spikelets per panicle and secondary rachis-branches per panicle”
e3
“while it seemed to increase with an increase in the number of panicles per unit area”
“A negative correlation was found between the dry matter increased during the period from the late spikelet initiation stage to the heading stage and the number of degenerated rachis-blanches”
The increase rate of early hybrid rice was correlated with cloudy days and mean temperature of shoots, with significant coefficients of 0.6094, 0.4799 and 0.6098.
“causes of low yield of early hybrid rice in Hainan Province were analyzed by relative survey method”
e2
“The correlative coefficient and multi-coefficient between increase rate and cloudy days and mean temperature of shoots were 0.6094 and 0.4799 and 0.6098 at 0.01and 0.05 and 0.05 significant level respectively”
“In comparison with lines-carriers of recessive allele vrd2, presence of dominant allele Vrd2 results into decrease of winter- and frost resistance, cutting time to heading increase of weight of grains for an ear and grain yield”
“28 conventional japonica rice varieties were selected to investigate the effects of TCB stress”
e2
“TCB caused sustained inhibition of the growth of japonica rice, which was considerably manifested in plant height, root length, soil plant analysis development (SPAD), and dry weight at different growth stages”
“Highly significantly negative correlations were recorded between ECe, cations (Na+, Ca++ and Mg++), anions (Cl- & SO=4) and each of some studied cotton genotypes characteristics (boll weight, 2.5 Spin length, lint percentage and plant height)”
“on a light loam calcareous Mollisol, having 23% clay content, with Illite clay mineral dominance. The soil is moderately supplied K. Corn as test plant was sown in monoculture in the trial. The first 10 years are evaluated in the paper. Soil K-test/AL-K/values did not decrease in the first 6 years, but diminished in the 7–10th years. The light loam soil did not fix the added fertilizer-K strongly.”
e1
“Yield losses, due to K-shortage, started when AL-K values dropped below 150 mg K kg−1 soil. The 1440 kg K2O/ha initial dose provided appropriate corn yield levels for 10 years, the 960 kg dose for 6 years, the 480 kg dose for 4 years, and the 240 kg dose for 1 year, on this soil, originally moderately supplied with potassium.”
“An unfavorable effect of using a small grain for sowing, fraction 2.2-2.5 mm, on 1000 grain weight of spring wheat manifested itself especially with the delayed sowing date”
