An experiment comparing crop regulation by pruning with crop regulation by disbunching is described. For three out of four seasons both methods of regulation gave similar yields, and only in one season did disbunched vines yield somewhat better than more severely pruned vines with the same number of bunches. This better yield appeared to be due to larger berries on the disbunched vines. Increased vegetative growth on the disbunched vines was not accompanied by improved fruit bud formation or by better bud burst in the following season. It is concluded that the leaf/fruit ratio has little effect on the yield of sultanas under Murray Valley conditions, and that methods of crop forecasting and regulation by pruning developed for this region should not be affected by the variation in leaf / fruit ratio to which they give rise.

Flower Bud Formation

The modifying effect of growth regulators on bud burst, flower bud formation and sex expression in olives varies greatly according to cultivar, concentration and time of application. Cycocel 200, 500 mg/l, ethephon 200 mg/l and SADH 2000 mg/l stimulated bud burst and flower bud formation in the 'Blanquetta' cv. A noticeable increase in the percentage of perfect flowers was obtained by 100 mg/l of kinetin, and 200 mg/l of Cycocel in the cv. 'Picual', Ethephon 200/1, Cycocel 200 mg/l and SADH 2000 mg/l considerably increased the percentage of perfect flowers in the cvs 'Blanquetta', 'Serrana' and 'Picual'. Treatments at green cluster stage were not effective.

Peach Trees

The vegetative growth of young peach trees was reduced greatly in the growing season following a dual infection with Prunus necrotic ringspot and prune dwarf viruses which caused the disease known as 'peach rosette and decline'. Ninety-two days after bud burst, the dry weight and leaf area of cv. Elberta scions were reduced by c. 60% as a result of infection, while the reduction in cv. Golden Queen was about 93%. The latter cultivar thus appears to be the less tolerant of infection by this virus disease.

Five field experiments with lupins (Lupinus angustifolius) measured the effectiveness, for production, of 4 superphosphate placements either: (i) drilled with the seed to a depth of 4 or 5 cm; (ii) applied to the soil surface (topdressed) before sowing; or (iii) banded 2.5-5 cm and 7.5-8 cm below the seed while sowing. Levels of applied phosphate (P) from 0 to 36 kg P/ha were tested. In all experiments lupin grain yield responded to the highest level of superphosphate applied. At this P level, the average grain yield from all trials was 1.16 t/ha for the deepest banded treatment. This was 0.38 t/ha (49%) better than P drilled with the seed, and 0.62 t/ha (115%) better than P topdressed. Relative to superphosphate drilled with the seed and regardless of the lupin cultivar or the phosphate status of the soil, the effectiveness of superphosphate was increased by 10-90% by banding below the seed, and decreased by 30-60% by topdressing. Increasing the levels of superphosphate drilled with the seed generally reduced the density of seedlings and reduced early vegetative growth, probably due to salt or P toxicity. However, during the growing season, the plants treated with high levels of superphosphate recovered, so that eventually yields of dried tops and grain responded to increasing superphosphate drilled with the seed. In each experiment there was a common relationship between yield and P content in lupin tissue, regardless of how the superphosphate was applied, suggesting that lupins responded solely to P, and other factors did not alter yield. We recommend that farmers band superphosphate 5-8 cm below the seed while sowing, rather than continue the present practices of either drilling the fertiliser with the seed, or topdressing it before sowing.

Meanwhile,attempts to increase national food production have beenlimited by availability of fertile lands. Our researchexploring natural bioregulator capable of improving cropproductivity, found that Sargasum sp., a wild sea weedgrown mostly along the coast line in Indonesia, indicated itsability to improve the growth and productivity of crops likerice, maize, tomato and oil palm even though with nochemical fertilizers added. The experiment on upland rice oflocal variety Batutegi planted in greenhouse, demonstratedthe natural bioregulator has increased the rice productivityby at least 50% over the control. The experiment usingmaize var. Arjuna, the bioregulator treated plants has madetwo to three corncobs instead of only one corncob on thecontrol plants. The experiment on the oil palm grown in thenursery showed that the bioregulator has significantlyinduced vegetative growth better than the control with orwithout chemical fertilizers. Intercropping the food crops,rice or maize in the juvenile phase of the oil palmplantations, should be beneficial to the productivity of theplantation.

THE INFLUENCE CHICKEN MANURE BOKASHI ON VEGETATIVE GROWTH OF BROWN MIDRIB SORGHUM (BMR) UNDER SHADE. The aim of this experiment was to study the effects of application of chicken manure bokashi on the vegetative growth of Brown Midrib (BMR) sorghum.  Completely Randomized Design (CRD) has been used according to Steel and Torrie (1995). The treatments were level of chicken manure  bokashi as follows B1= 0 gram; B2= 200 gram; B3= 400 gram and B4=  800 gram/polybag, with 7 replications to form 28 numbers of observations. The variables measured were plant height, leaf number and  length of leaf. Analysis of Variance showed that treatments effected significanly different (P<0.05) on plant height, leaf number and length of leaf. Result of Tuckey Simultenaus Test showed that between treatment B3 and B4 were not significant different (P>0.05) on all variable measured, but both treatments gave a good performance of all variable measured significantly (P<0,05) better than treatments  B2 and B1. Based on this research result it can be concluded that utilization of chicken manure bokashi up to 400 gram/polybag could provide nutrients requirement to support vegetative growth of sorghum BMR in term of height of plant, leaf number and length of leaf. Keywords: Bokashi, chicken manure, growth, BMR sorghum, shaded.

Mean Time

Sultana vines were examined during bud burst for four seasons, and the date on which each shoot arose was noted. The shoots were later classified as fruitful, barren, or defective. The vines were pruned uniformly in the first season, and two pruning treatments were compared in the other three seasons. In all cases the mean time of bursting a t each bud position was progressively later from the distal to the proximal end of the cane, the number of newly burst buds found at each examination was related to preceding temperatures, and the percentage of fruitful shoots among new shoots found at each examination decreased from the beginning to the end of bud burst. Accessory shoots arising as a result of the death of primary shoots or buds were very rarely fruitful. The results are considered in relation to the discrepancy sometimes found between the percentage of fruitful buds and the percentage of fruitful shoots.

Field And Laboratory Conditions

A study of the effect of environmental factors on the growth and development of the lowbush blueberry was carried out using clonally propagated plants. In a preliminary study a definite photoperiodic response was found. Under 8-hour days flower buds were formed and no vegetative growth occurred. Under 16-hour days vegetative growth resulted and no flower bud formation occurred. In a replicated greenhouse experiment, seven clones produced flower buds with 8-, 10-, and 12-hour days, but produced none with 14- or 16-hour days. One clone produced flower buds with 8-, 10,- 12-, and 14-, but none with 16-hour days. Two clones were able to produce flower buds under all five photoperiods. Under 8- and 10- hour photoperiods no vegetative growth occurred. Under 12, 14, and 16 hours progressively more vegetative growth occurred. In an experiment on the interaction of temperature and photoperiod, vegetative growth was significantly greater at 70° F than at 50° F with the differences being accentuated by day length. Flower bud formation occurred with 11- and 13-hour photoperiods regardless of temperature, but was more pronounced at the higher temperatures. At 70° F, 15-hour photoperiod, no flower buds were formed while at 50° F, 15 hours, three clones produced no flower buds and six clones produced an abnormal type of inflorescence. Similar abnormal inflorescences were produced by giving plants 2, 3, or 4 weeks of 8-hour days. Six weeks of 8-hour days was sufficient to initiate normal inflorescences. Shade, provided by two layers of cheesecloth, significantly reduced the number of flower buds compared with full sunlight. The growth of the lowbush blueberry under field and laboratory conditions is discussed in relation to environmental factors.

Hypocotyl segments excised from seedlings of Santalum album (sandalwood tree) grown in vitro were cultured aseptically on various nutrient media. Regeneration of shoot buds on explants was observed on basal media supplemented with auxins like IAA, IBA, NAA, or NOA. Shoot bud formation was completely suppressed on 2,4-D or pCPA medium. Cytokinins stimulated and enhanced shoot bud formation better than auxins. Excised stem segments from adult plants did not respond to any hormonal treatment. The importance of this method in the propagation of the sandalwood tree is emphasized.

And Chemical Properties

The experiment was conducted during two successive seasons 2016 and 2017 on sweet pepper plants to study the effect of foliar application of some natural extracts (fulvic acid at 2, 4 and 6% or algae at 1, 2 and 4 g.L-1) were applied three times along each season (after 2, 4 and 6 weeks of planting). The influence was evaluated through the response of vegetative growth, and some physical and chemical characteristics of sweet pepper fruits. The results obtained showed that the algae extract at 1 g.L-1 in most cases was better than the other spray treatments investigated to improve most fruit characteristics (length, diameter and yield of fruits), vegetative growth, and chemical properties followed by 6% fulvic acid. With regard to organic acids, malic and citric acids are the main organic acids found in sweet pepper. Malic, succinic and glutaric acids were higher in 1 g.L-1 algae extract treatment, but the concentration of citric acid was higher in 6% fulvic acid treatment. Therefore, algae extract and fulvic acid could be safely recommended as a natural biostimulants application for improving most desirable characteristics of sweet pepper grown under the same experimental condition.
