Field experiments were done in three successive seasons to determine the effects of cultivar and row spacing on growth, yield and quality of cotton. Narrow rows had a higher early season LAI than wide rows, but differences in LAI between row spacings disappeared by the peak flowering stage. Hopicala and Deltapine 16 had a higher LAI than Riverina Poplar and Super Okra M8. Narrow rows produced 28 per cent more fruiting points than wide rows, but this was not reflected as a consistent increase in yield, as fruit shedding was greater and boll size was smaller in narrow rows than in wide rows. Narrow rows yielded 44 per cent more than wide rows in 1972-73 but 7 per cent less in 1973-74 and 1 per cent less in 1974-75. Earlier crop maturity was obtained with narrow rows in all cultivars in 1974-75 and Hopicala only in 1972-73. Deltapine 16 and Super Okra M8 had the highest average yield at both row spacings, with Super Okra M8 having the highest yield at the first pick. No fibre properties were consistently affected by row spacing. Cultivar differences were as expected with the early maturing cultivar Riverina Poplar having the shortest fibres and the later maturing cultivar Hopicala having the greatest fibre strength.

Yield And Quality

Water pumping restrictions of high-quality irrigation water from underground aquifers is affecting vegetable production in Southwest Texas. There is a need to develop efficient deficit-irrigation strategies to minimize irrigation inputs and maintain crop profitability. Our objective was to determine how growth, yield, and quality of cantaloupe (Cucumis melo L. cv. `Caravelle') are affected by irrigation systems with varying input levels, including drip depth position and polyethylene mulch. Stand establishment systems used were containerized transplants and direct seeding. Field experiments were conducted on a Uvalde silty clay loam soil. Marketable yields increased in the order of pre-irrigation followed by: dry-land conditions, furrow/no-mulch, furrow/mulch, drip-surface (0 cm depth)/mulch, drip-subsurface (10-cm depth)/mulch, and drip-subsurface (30 cm depth)/mulch. Pooled across all drip depth treatments, plants on drip had higher water use efficiency than plants on furrow/no-mulch or furrow/mulch systems. Transplants with drip-surface produced 75% higher total and fruit size No. 9 yields than drip-subsurface (10- or 30-cm depth) during the first harvest, but total yields were unaffected by drip tape position. About similar trends were measured in a subsequent study except for a significant irrigation system (stand establishment interaction for yield. Total yields were highest for transplants on drip-subsurface (10-cm depth) and direct seeded plants on drip-subsurface (10 and 30 cm depth) with mulch.

Garlic is primarily grown for its cloves used mostly as a food flavoring condiment. Previous studies carried out on plant density indicate its direct influence on yield. Plant density depends on the genotype, environmental factors, cultural practices, etc. This study was established to determine the effects of different between-row spacing on growth, yield, and quality of four local accession of garlic. It was laid out on two-factorial Randomized Complete Block Design with three replications during two years. Four local accession of garlic (Langroud, Tarom, Tabriz and Hamedan) were culture in three between-rows spacing (15, 25 and 35 cm) during two years. The results of two cultivated years were different. Plant density changed when garlic cultured with different between row spacing. In present research plant yield increased when the lower between row spacing and high plant density were used but the yield improvement occurring at increased plant stand is offset by the reduction in bulb size and some quality indices such as total phenol and antioxidant which severely affects quality and market value, when garlic is produced for fresh market.

The influence of a growth regulator, chlorocholine chloride (commercial name Cycocel 75) on plant growth, (yield) and quality of late-seeded (mid-December) cotton (Gossypium hirsutum) was studied in the Río Dulce Irrigation Area, northwest Argentina, during three growth cycles (1998–2001). Cycocel 75 reduced plant height and node number as well as the total production of aerial biomass, thus increasing the harvest index. Due to an increase in the boll weight and boll number per plant, the yield of treated plots increased by an average of 35% in comparison with the control. Cycocel 75 improved fibre strength significantly, although other parameters of fibre quality, such as length, uniformity, elongation, and micronaire index were not affected. This study indicated that late-planted cotton responds favourably to the application of Cycocel 75, especially when its development cycle is extended due to low air temperatures during the latter part of the growing season.

SUMMARYThe effects of three irrigation regimes on growth, yield and quality of cotton were investigated for two seasons in relation to earliness, quality and water-use efficiency, expressed as m. of water/kg. cotton produced. Light irrigations of cotton, at 75 mm. per irrigation every ten days, were economically better than the traditionally-accepted practice of irrigating every 14 days, and markedly better than prolonging the irrigation cycle to 20 days, mainly due to increased market value of the crop. The results also showed that irrigation intervals of 20 days, besides depressing yield, had a deleterious effect on fibre strength, though the different water regimes did not seem to affect other quality tests.

Two field experiments were conducted during two seasons of 2017 and 2018 to evaluate the effect of both bio-fertilizer (inoculated or uninoculated) and selenium (Se) spray at 0.5, and 10 ppm on vegetative growth, pigments, yield and quality of potato plants. The results indicated that, vegetative growth characters (number of leaves, plant height, plant fresh weight, plant dry weight, leaf area and leaf pigments (chlorophyll a, chlorophyll b and chlorophyll a and b were significantly increased with Bio-fertilizers (Halex-2, and High rate of Se (10 ppm), in both seasons. Plant yield of tuber, number of tubers/plant, average tuber weight and tuber yield/Fed and (tuber content of starch and protein), generally, seemed to be increased with the Bio-fertilizer (Halex-2) and high rate of Se, in both growing seasons. The interaction between Bio-fertilizer (Halex-2) and Se reflected positive effects on the all studied quantitative and qualitative characters of potato plants.

No significant lint or seed cotton yield differences were found between a normal leaf cultivar of cotton and its near-isogenic superokra leaf counterpart in three experiments over three seasons at Kimberley Research Station in north-western Australia. There were also no significant interactions for lint yield of the two lines with variations in inter-row spacing and nitrogen application. Differences in quality between the two were also slight and of no commercial importance. The superokra leaf gene, however, caused earlier maturity and decreased production of leaf and stem tissue. Biologically superokra leaf was more efficient, with a greater production of seed cotton per unit of leaf tissue than for the normal leaf. Superokra leaf led to increased difficulty of weed control in conventional 1-metre cotton culture, but it appeared a desirable factor to transfer to cultivars bred for narrow-row high density cotton.

Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore, India during the North East Monsoon (October-December) seasons of 1997 and 1998 in a split plot design to study the effect of planting pattern and N splits on the yield attributes, yield and quality of rainfed sunflower. The main plot consisted of three plant populations (133,333 plants ha-1, 111,111 plants ha-1 and 88,888 plants ha-1) and the sub-plot treatments of six N split levels. The results revealed that the yield attributes of sunflower were higher at the closest spacing of 30 × 25 cm than at the widest spacing of 30 × 37.5 cm. The seed yield was higher at closer (30 × 25 cm) spacing in 1997 and at wider spacing (30 × 37.5 cm) in 1998. In both years the split application of nitrogen resulted in higher growth, yield attributes, seed yield and quality parameters when compared to full basal application.
