“…4) show that total protein content increased considerably with increase in nitrogen supply of the growth medium. The results are similar with earlier finding of Menezes et al (1999) working with Pearl Millet (Pennisetum glaucum (R) Br. ): he reported that supra-optimal nitrogen application reduces the growth and grain yield but it caused an increase in protein.…”

Pests are major factor affecting the crop yield, quality, and esthetic value. Although pest resistance is genetically controlled, it is mediated through physiological and biochemical processes interrelated with the nutritional status of the plant. Nutrition of plant may determine its resistance or susceptibility to pests. An experiment was conducted to determine whether and up to what extent varying concentrations of N modulate the infesting rate of whitefly on Okra (Hibiscus esculentus). Twenty-one-dayold okra plants were subjected to five concentrations of 4, 8, 12, 16, and 20 mM N for 30 days. Number of eggs, nymph were counted on each plant after every 4 days. Growth and yield of okra plants increased with increasing supply of N but it decreased slightly at the highest level of N (20 mM). Leaf soluble proteins, amino acids, and soluble sugars were determined on fresh weight basis. From these results, it is clear that increasing N level increased the biosynthesis or accumulation of protein, free amino acid, and sugars that might have attracted more whitefly for feeding.

“…In Eastern Nebraska, a significant increase in grain yield of pearl millet with application rate of 78 kg N ha -1 was observed by Maman, Mason, Galusha, and Clegg (1999) and Limon-Ortega et al (1998). According to Menezes, Gascho, and Hanna (1999), highest pearl millet yield resulted from N rate of 112 kg ha -1 . On the other hand, N-fertilizer applications have also been reported to be associated with decreased grain yield under late planting situations, drought conditions or high levels of mineral N in soil.…”

Pearl millet (Pennisetum glaucum [L.] R. Br) has the requisite characteristics for dry land production in the southeastern USA in comparison to the traditional grain crops while requiring less input. The purpose of this study was to identify the genotypes that produce the highest yield and seed quality at different rates of nitrogen. Four pearl millet genotypes (2304, LHB08, 606A1*2304 and 707A1*4280) were cultivated on secondary land and treated with 4 different nitrogen rates: 0, 40, 80 and 120 kg ha -1 . The genotypes were evaluated for agronomic parameters including booting, number of tillers, plant height, plant weight, number of heads, head length and yield. Nitrogen rate did not have any significant effect on the head length, number of tillers and plant (dry) weight among the genotypes. Plant height ranged between 96 and 111 cm and was significantly different among the genotypes. However, numerically, genotype LHB08 produced the longest heads (42 cm) and highest seed yield (6,159 kg ha -1 ) across all treatments. Overall, nitrogen rate did not produce significant difference in yield among the genotypes. Since grain yield obtained in this study is comparable to those reported elsewhere, it can be inferred that pearl millet has the potential as a new grain crop for the southeastern United States. Furthermore, results demonstrated that pearl millet can be grown with limited N-input. As N-fertilization is the major cost of producing any crop, pearl millet offers special opportunity for large number of limited resource farmers in the region.

“…At the Dixon site, the grain N concentration was also slightly higher with cattle manure than with hog manure. Splitting fertilizer N application to increase N supply in the later stage of growth increases grain N concentration in pearl millet (Pennisetum glaucum (R.) Br) in comparison to a single large application at the planting (Menezes et al, 1999). Through slow mineralization, the residual cattle manure may have provided an extended supply of available N to the wheat in the late stages of growth.…”

SummaryThe efficiency of nitrogen (N) derived from different manures in the years following application must be determined to optimize use of N and reduce impact on the environment. Five N efficiency parameters that were originally developed for commercial inorganic N fertilizers were selected to measure the manure N efficiency in the second year following application of liquid hog and solid cattle manure in semiarid east-central Saskatchewan, Canada. The manures were applied at two sites (Dixon and Burr) at four rates covering a range from zero to 912 kg N ha ±1 in 1997. A canola (Brassica napus L.) crop was grown in 1997 followed by a spring wheat (Triticum aestivum L.) in 1998 without fertilization. Tested by the wheat, N utilization efficiency (NUE) was similar between the two manures at either site, but it was higher at Dixon site, where the soil properties were better, than at the Burr site (P < 0.07) with cattle manure. Nitrogen physiological efficiency (NPE) was not affected by either manure source or soil. At the Burr site, N agronomic efficiency (NAE) and N recovery rate (NRR) were all higher with the hog than with the cattle manure (P < 0.08 and P < 0.07, respectively), but N harvest index (NHI) was lower with the hog than with the cattle manure (P < 0.04). The similar trends of the NAE, NRR, and NHI between the hog and cattle manure were also found at the Dixon site. However, the differences in NRR between the hog and cattle manure in the second year was rather small in contrast to the large differences in the year of application. Despite that the wheat crop utilized residual hog and cattle manure N equally efficient in producing grain yield, a higher grain N concentration and a higher NHI with the cattle than with the hog manure revealed different N supply dynamics between the two. Possibly due to the low proportion of ammonium (NH 3 )-N in the total N and the high C : N ratio in the cattle manure, mineralization of cattle manure N provided more available N in the later stage of wheat growth than did the hog manure. The N efficiency parameters were useful tools in understanding the impact of residual manure N on wheat production on the Canadian prairies.Key words: liquid hog manure / solid cattle manure / nitrogen utilization efficiency / nitrogen physiological efficiency / nitrogen agronomic efficiency / nitrogen recovery rate / nitrogen harvest index PNSS P113/5B
