Fertility level

Jiaogulan (Gynostemma pentaphyllum (Thunb.) Makino) is distributed mostly in mountainous areas, in shaded and humid places at 300-3200 meters above sea level. This study was conducted to determine the appropriate application dose of nitrogen for the growth of Jiaogulan under different shading conditions.

To study the impact of artificial creation of soil fertility gradient strategy on soil fertility, nutrient uptake and green fodder yield of sorghum (var. CO 30) by following inductive methodology (fertility gradient concept), a field experiment was conducted during 2014-15 at farmer’s holding of Coimbatore district. The experimental field was divided into three equal strips and three graded levels of fertiliser N, P2O5 and K2O were applied in the form of urea, single super phosphate and muriate of potash, respectively to strip I (N0P0K0), II (N1P1K1) and III (N2P2K2).

The estimates of genotypic correlation coefficients in general were higher than their corresponding phenotypic correlation coefficients indicating strong inherent association among the traits. The seed yield per plant had significant and positive association with number of primary branches plant-1, number of secondary branches plant-1 , number of pods plant-1 , number of seeds plant-1 , biological yield plant-1 , seed yield (kg/ha) harvest index and 100-seed weight at both genotypic as well as phenotypic levels.

three groups of 40 perch breeders were reared in order to study the effects of 3 different levels of dietary n-3 and n-6 fatty acids on egg quality. two experimental diets, r1 and r2 (n-3/n-6 = 0.13 and 35.54, respectively), were compared to one commercial food, r3 (n-3/n-6 = 3.48). spawning and fertilization rates were high for diets r1 and r3, which displayed a n-3/n-6 ratio of 0.77 and 2.34 in the eggs, respectively, by comparison with r2 (n-3/n-6 = 4.87), which produced low reproductive performances. We can conclude that dietary n-3 and n-6 FA levels influence egg and larval...
