SUMMARYThe effect of available water on yield (e.g. Waring, Fox and Teakle, 1958) and of nitrogen on yield and quality (e.g. Waring and Teakle, 1960) have been examined for wheat grown on black earths of the Darling Downs in Queensland. However, the joint effect and individual contributions of nitrogen and water to this effect in the field appear to have been neglected. Further, the condition known as mottled wheat, described by Wood (1960), is an important problem in the wheat industry, and it was felt by the authors that this condition was the result of a water-protein yield complex. It was therefore decided to examine the effects on yield, total protein and mottling of applications of nitrogen and water in a soil where these were deficient.

Three Stages

A study was conducted at two locations to evaluate the effects of cheat (Bromus secalinusL. ♯3BROSE) competition on four seeding rates (4.5, 9.0, 13.5, and 22 kg/ha) of alfalfa (Medicago sativaL. ‘Riley’). Three stages of first harvest (early bud, early bloom, and late bloom) were imposed on fall-planted alfalfa, with and without cheat overseeding, to determine the effects of harvest stage on alfalfa yield and quality. Cheat infestations significantly decreased alfalfa production and forage quality. Increasing the seeding rate of alfalfa only partially offset these losses. Harvesting early helped minimize the effect of cheat competition. First-harvest protein yield of forage was significantly decreased by, cheat overseeding. Total protein yield at first harvest was not affected by cutting stage but did increase with the two higher seeding rates of alfalfa.

A pulsed-cap microcolumn was used for bromelain extraction from pineapple juice by reversed micelles. The cationic micellar solution used BDBAC as the surfactant, isooctane as the solvent and hexanol as the co-solvent. In order to capture the dynamic behavior and the nonlinearities of the column, the operating conditions were modified in accordance with the central composite design for the experiment, using the ratio between the light phase flow rate and the total flow rate, and the time interval between pulses. The effects on the purification factor and on total protein yield were modeled via neural networks. The best topology was defined as 16-9-2, and the input layer was a moving window of the independent variables. The neural model successfully predicted both the purification factor and the total protein yield from historical data. At the optimal operating point, a purification factor of 4.96 and a productivity of 1.29 mL/min were obtained.

Goat breeding is one of the least developed agricultural sectors in Serbia. This is reflected in the fact that the total number of goats in Serbia is less than 200,000, as well as the fact that no goat milk production has been recorded by the statistics. Over the last decade, there has been great interest of breeders for intensive breeding of highly productive goats, which resulted in imports of breeding goats. In the same period, several herds of the Alpine breed and German fawn goats were formed, while their production results in the growing conditions in our country have not been fully studied yet. During the first three lactations in the period 2003-2009, the following parameters of milk yield were studied: length of lactation, milk yield in one lactation, percentage and the milk fat yield, and percentage and the total protein yield. The average lactation period was 247 days for the first, 260.6 days for the second and 266.8 days for the third lactation. The average of milk yielded was constantly increasing from the first (594.51 kg) towards the third lactation (761.96 kg), showing statistically highly significant differences (P<0,001). What was also observed is that the order of lactation has not significantly affected the percentage of proteins in milk, whereas the total protein yield in lactations was influenced by the order of lactation due to the differences in average milk yield in lactations.

In a greenhouse pot experiment with kohlrabi, variety Luna, we explored the joint effect of N (0.6 g N per pot = 6 kg of soil) and S in the soil (25-35-45 mg kg-1 of S) on yields, on N, S and NO3- content in tubers and leaves, and on alterations in the amino acids concentration in the tubers. S fertilisation had no effect on tuber yields. The ranges of N content in tubers and leaves were narrow (between 1.42-1.48 % N and 1.21-1.35 % N, respectively) and the effect of S fertilisation was insignificant. S concentration in the tubers ranged between 0.59 and 0.64 % S. S fertilisation had a more pronounced effect on the S concentration in leaf tissues where it increased from 0.50 to 0.58 or to 0.76 % S under the applied dose. The NO3- content was higher in tubers than in leaves. Increasing the S level in the soil significantly reduced NO3- concentrations in the tubers by 42.2-53.6 % and in the leaves by 8.8-21.7 %. Increasing the S content in the soil reduced the concentration of cysteine + methionine by 16-28 %. The values of valine, tyrosine, aspartic acid and serine were constant. In the S0, S1, and S2 treatments the levels of threonine, isoleucine, leucine, arginine, the sum of essential amino acids and alanine decreased from 37 to 9 %. The histidine concentration increased with increasing S fertilisation. S fertilisation of kohlrabi can be recommended to stabilize the yield and reduce the undesirable NO3- contained in the parts used for consumption.

Among genotypes, Dekalb 900 M Gold recorded significantly higher dry matter/plant, LAI, cobs placement height, grain yield, nitrogen content, protein content, protein yield and protein productivity than other genotypes. Leaves/plant and phytosynthetically active radiation (PAR) above canopy did not influenced by genotypes. Dry matter/plant, plant height, LAI, cobs placement height, protein content, protein yield and protein productivity exhibited higher under highest levels of nitrogen (160 kg N/ha), but at par with 120 kg N/ha. However, grain yield (6300 kg/ha) was highest under nitrogen levels of 120 kg/ha, but also at par with 160 kg N/ha (6240 kg/ha). The effect of applied nitrogen was found non-significant in respect of leaves/plant, PAR above and below canopy, photosynthetically active radiation interception and days taken to tasseling and silking.

The Cost

The objective of this study was to compare the performance of male fertility restored intercultivar F1 hybrids in the nap and pol cytoplasms to determine the relative effect on performance of these two male sterility inducing cytoplasms. F1 hybrids (all were 2n = 39 because a common 2n = 40 restorer line was used to produce the F1 hybrids) in both cytoplasms exhibited superior relative performance compared to the conventional cultivar Regent for seed yield, total dry matter and total protein yield. F1 hybrids in the pol cytoplasm performed significantly poorer than F1 hybrids in the nap cytoplasm for seed yield, total dry matter, harvest index, percent oil, total oil yield, and total protein yield. These results suggest a biological cost associated with the presence of the pol cytoplasm. The cost of the pol cytoplasm, relative to the nap cytoplasm, was affected by parental cultivar, but was consistent over a variety of environments.Key words: Cytoplasm cost, Brassica napus L., cytoplasmic male sterility, heterosis, hybrid

A field study was conducted at Grdarasha Research Station of the College of Agriculture/Salahaddin University, Erbil, during growing winter season of 2017, to study the effect of plant spacing on some yield and quality of chickpea varieties. The factorial experiment was applied in "Randomized Complete Block Design" (RCBD), in three replicates, by using four plant spacing (6, 9, 12 and 15 cm), and three varieties of chickpea (Rafedain, Gab and TH85) were implemented. The 15 cm plant spacing produced the highest number of primary branches per plant (4.34), number of pods per plant (15.44), seed yield (1124.33 kg/ha), protein percentage (23.12), protein yield (247.19 kg/ha), and oil percentage (11.81). On the contrary, the 6 cm plant spacing recorded the highest value of carbohydrate percentage (60.91); also, Gab variety exceeds Rafedain and TH85 varieties in number of primary branch per plant (4.07), number of pods per plant (11.71), seed yield (1120.91 kg/ha), protein percentage (22.25), and protein yield (250.26 kg/ha), but the TH85 gave the optimum oil percentage (11.14) and carbohydrate percentage (59.84). From the interaction of plant spacing with varieties, the highest rate was recorded at 15 cm plant spacing with Gab variety seed yield (1192.85 kg/ha) and protein yield (297.16 kg/ha). There was a positive and negative correlation between yield and number of pods per plant and number of seeds per pod (r = 0.673 and 0.689) and between carbohydrate percentage with protein and oil percentages (r = −0.777 and −0.658), respectively.
