Yield And Quality

Changes in growth, yield, and fruit quality of citrus in a factorial field experiment are presented. Nitrogen fertilization in the sod treatment had only limited effects on yield. After the application of superphosphate, yields at the higher nitrogen levels increased markedly. The initially superior yields from the bare surface treatment decreased gradually, and became at the highest nitrogen level even lower than in the tilled treatments. After application of superphosphate, yields improved in the plots receiving ample nitrogen and became even higher than in the tilled treatments. Yields in the tilled treatments remained good, and were not influenced by nitrogen fertilization. Fruit quality in the no-tillage treatments improved considerably after the application of superphosphate. Increasing nitrogen supply, however, had a depressing effect on fruit quality in all cultural treatment's, but within each nitrogen level the fruit was of similar quality. Nitrogen and phosphorus contents of leaves sampled in 1954 and 1957 are compared, and the changes in yield and quality that occurred during that period are discussed in relation to the modified phosphorus supply in the experiment.

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.

Chlorophyll A Content

The experimental layout was designed in completely randomized complete block with 4 replicates in the combination of nitrogen levels of 28,8; 60; 90; 120 kg/ha with potassium of 0 and 30 kg/ha in order to investigate the effects of fertilization on growth, yield and quality of bon bon (Cattail) in Ca Mau province. At 90days after planting, treatments with higher levels of nitrogen application increased in plant height, tiller number, weight of edible part, fresh and dry biomass. Variations in nitrogen and potassium levels caused no change in photosynthetic pigments but chlorophyll a content was always about more than triple more than that of chlorophyll b. Potassium contributed to enhancinge plant height, biomass, edible part weight but difference in tiller number was not found between the two levels. Higher levels of nitrogen in combination with potassium not only enhanced biomass yield but also improved quality by increasing levels of soluble sugars and protein in the edible part. The interactions between nitrogen and potassium levels were recognizedpositively affected on growth, yield, and quality of cattail; therefore, it is highly recommended to apply both these nutrients when growing this crop.

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.
