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.

This study aims to improve the growth, yield, and quality of LP-VoS bulbs by applying bokashi fertilizer from goat manure and regulating the duration of water supply with a sprinkler irrigation system. This research is a field that arranged in split-plot design. The main plot is the duration of irrigation water supply, consisting of three levels, 0.5; 1,0; and 1.5 hours. The subplot is giving organic fertilizer bokashi goat manure, which consists of two kinds, namely: without bokashi fertilizer and the addition of bokashi fertilizer 15 t.ha-1. Each treatment was repeated three times so that in total, there were 18 experimental plot units. The results showed that the duration of irrigation 0.5 hours at intervals of 3 days, followed by the application of 15 t.ha-1 bokashi organic fertilizer could increase the bulb circle of 'Lembah Palu' varieties.The use of bokashi organic fertilizer 15 t.ha-1 could increase soil moisture so it can growth, yields, and quality of shallot bulb. The duration of irrigation with a sprinkler system for 0.5-1.0 hours at intervals of 3 days could result in the growth of total dry weight and total leaf area per plant as well as the number of tubers per clump, fresh weight of tubers per clump and yield of tubers per hectare higher than treatment of water for 1.5 hours at intervals of 3 days. Water supply regulations and the use of bokashi organic fertilizers can increase the growth, yield, and quality of LP-VoS bulbs on dryland. For the cultivation of‘Lembah Palu’ varieties of shallots in dry land, it is necessary to apply organic fertilizers to increase the soil water content for increased production and quality.

Abstract Background Antioxidants or vitamins are organic compounds that are needed in tiny quantities and have stimulatory role on growth and productivity of different plants. Two field experiments were conducted in two summer seasons to investigate the role of two irrigation systems (spraying and dripping) and α-tocopherol foliar treatment with different concentrations (0, 100 and 200 mg/L) on some growth indices and physiological aspects, yield and its components of sweet corn plants. Results The results show that dripping irrigation system was more effective than Sprinkler system on increasing the studied growth indices and biochemical attributes as well as yield quantity and quality. The results also show the enhancing effect of different α-tocopherol treatments on growth indices, and yield quantity and quality of the sweet corn varieties via enhancing photosynthetic pigments, indole acetic acid, phenolics, carbohydrates constituents, free amino acids and proline contents. Moreover, the interaction between the two irrigation systems and different concentrations α-tocopherol showed that, dripping irrigation with 200 mg/L α-tocopherol was the most effective treatment on increasing growth, yield and yield components of sweet corn plants. Conclusion It could be concluded that dripping irrigation system was more effective than Sprinkler system on increasing the studied growth indices and physiological aspects, yield and its constituents. Moreover, treatment of maize plant with α-tocopherol could improve the studied growth indices, physiological aspects and consequently yield.

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.

Proper nutrition is one of the factors which is limiting onion production. Onion yield and quality is affected by fertilization of macro and micro nutrients. Mineral nutrients, Nitrogen, phosphorous and Potassium are macronutrients which significantly affect onion production. Nitrogen and phosphorous fertilization significantly affect growth, yield and quality of onion. The requirement of mineral fertilizer varies from place to place, depending on different factors in the growing areas. Effective use of N, P and K fertilizer depends on soil condition, irrigation system, climatic factors and management factors. In all different research reports, it is described that onion is a heavy feeder for N, P, K and the application of these mineral elements enhance production significantly. The quality of onion, physiology and production is highly limited by fertilization of N, P and K fertilizers. Therefore, in this review the effect of mineral nutrition on growth, physiology and yield of onion are discussed and examined in detail.

Rootstocks in various species have been shown to significantly influence vigor of scion growth, yield, fruit size, maturity, quality, and other phenomena. This research studied the effects of combinations of three scions and three rootstocks of Iranian pistachio on characteristics of fruit. A split-plot design was laid out at Rafsanjan/Iran in 1993 and results for a period of 2 years from 1994 to 1995 are presented. Diameter of trunk 5 cm above and below the graft area, weight of nuts with hull, weight of nuts without hull, weight of in-shell nuts, weight of blank, percent of shell splitting and total yield weight were measured. Almost all the treatment differences in the experiment were associated with rootstock effects and not scions. Statistical analysis indicated that different scions had no effect on any of the measured characteristics except the diameter of trunk 5 cm below the graft area. Rootstocks, however, had large and significant effects on all the characters except percent shell splitting. Interactions between scion and rootstock were important such that the combination of the scion `Kalehghochi' with the rootstock `Ahli' gave substantially higher yields than any other combination.

Yield And Quality

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.
