This study investigated the influence of three soil moisture irrigation regimes on concentration of seed iron and zinc content of four biofortified bean varieties promoted for eradication of malnutrition in Sud-Kivu highlands. A field experiment was conducted in the Hogola marsh highlands during two cultural seasons B2013 and B2014. The experiment design was a RCBD with a split plot arrangement where the main plots were 110 m2 and split plots 20 m2. A strategic application of homogenisation of the experimental site’s soil fertility by chemical fertilizers of the type: CaCO3, KCl and DAP was conducted out. Four biofortified varieties (CODMLB001, RWR2245, HM21-7 and RWK10) constituted main factor, while water regimes respectively [bottom of the slope: R1 = 48% soil moisture, at the middle of the slope R2 = 37% soil moisture and at the top of the slope: R3 = 29% soil moisture according to the gradient of humidity] represented secondary factor and seasonality, tertiary factor. The study showed that the concentrations of iron and zinc were highly correlated with soil moisture regimes. The variety HM21-7 demonstrated better adaptability because it showed a low rate of reduction of iron and zinc concentration under the three soil moisture regimes and was therefore best suited to fight malnutrition in the Sud-Kivu province.

Experiments were conducted in growth chambers growing wheat on a soil initially low in NO3-N. At rates up to 100 ppm N, grain yield increased with succeeding increments of fertilizer-N. Increased temperatures (15, 21, and 25 C) significantly decreased grain yield in most instances. Low to moderate stress soil moisture regimes (0.3–0.5 and 0.3–2.8 bars) had no significant influence on grain yield. A line was plotted for percent protein vs. added fertilizer-N resulting in a concave protein curve, with an initial decrease in protein to 50 ppm N and a subsequent rise with 100 and 200 ppm N. At each level of N, a close negative correlation was shown between percent protein and grain yield. The effect of increased temperature in increasing percent protein was found to be mostly an indirect effect through the influence of temperature on grain yield. Moisture regime was found to have no significant direct effect on percent protein.

Abstract Integrated nutrient management strategies involving chemical and biologic fertilizer is a real challenge to stop using the high rates of agrochemicals and to enhance sustainability of crop production. In order to study the effects of livestock manure, chemical nitrogen, and biologic (Azotobacter) fertilizers on yield and yield components of wheat, an agricultural experiment in the form of split factorial design with three replications was conducted in Elam region, Iran. The aim of this research was assessment of the effects of these fertilizers separately and in integrated forms; and setting out the best fertilizer mixture. The results showed that treatment with livestock manure, Azotobacter and chemical nitrogen increased plant height, biological and grain yield. Using livestock manure and Azotobacter increased biologic yield through increase in plant height which cause to increase in grain yield without any significant changes in harvest index and other yield components, but the use of chemical nitrogen caused an increase in plant height, No. of spikelete/spike, No. of grain/spike, one thousand grain weight and harvest index, biologic and grain yield. In the light of the results achieved, we may conclude that using livestock manure and chemical nitrogen fertilizer together with the Azotobacter had the maximum impact on yield; and that we can decrease use of chemical fertilizers through using livestock manure and biologic fertilizers and to reach to the same yield when we use only chemical fertilizers.

The experiment comprised of 10 treatments, such as T0: Control condition; T1: All chemical fertilizer as recommended dose; T2: Cowdung as recommended dose; T3: Compost as recommended dose; T4: ½ Cowdung + ½ Compost; T5: Cowdung + Compost; T6: Cowdung + ½ Chemical fertilizer; T7: Compost + ½ Chemical fertilizer; T8: Cowdung + Compost +½ Chemical fertilizer and T9: ½ Cowdung + ½ Compost + ½ Chemical fertilizer. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Data on different growth characters and yield were recorded. Among the treatments all chemical fertilizers as recommended dose (T1) and cowdung + compost + ½ chemical fertilizer (T8) were found superior considering all yield contributing characters and yield. At 30 (Days after Sowing) DAS, the longest plant was recorded from T8 (27.93 cm), while the shortest plant was found in T0 (23.13 cm). At 50, 70, 90 DAS and harvest the longest plant was recorded from T1 (52.13 cm, 82.13 cm, 85.93 cm and 95.21 cm), whereas the shortest plant was obtained from T0 (41.14 cm, 65.84 cm, 70.77 cm and 76.00 cm). At 30, 50, 70, 90 DAS and harvest the maximum number of tillers hill-1 was recorded from T1 (2.00, 5.64, 6.93, 6.15 and 5.78), whereas the minimum number was found in T0 (1.33, 2.87, 4.20, 3.94 and 3.72). The longest spike (19.86 cm), maximum number of spikelets spikes-1 (20.33), maximum number of filled grains spike-1 (34.00), highest grain yield (3.71 t ha-1) and highest straw yield (5.78 t ha-1) was attained from T1 and the shortest spike (14.33 cm), minimum number of spikelets spikes-1 (14.18), minimum number of filled grains spike-1 (21.53), lowest grain yield (2.06 t ha-1) and lowest straw yield (4.49 t ha-1) was recorded from T0.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22066 J.

Major Factors

Reduced spikelet fertility appears to be one of the major factors responsible for the decreased rice grain yield when cultivated under semi irrigated aerobic condition. We demonstrate that genotypes with better root systems coupled with higher cellular level tolerance (CLT) can significantly improve spikelet fertility under semi-irrigated aerobic condition in the field. A set of 20 contrasting rice accessions differing in root traits and CLT with significant molecular diversity were subjected to specific soil moisture regimes during a period between five days before and 10 days after anthesis. Lowest spikelet fertility was observed among the plants grown under water limited (WL) conditions followed by the plants grown aerobically in field conditions (AF). Deep rooted genotypes generally maintained higher spikelet fertility under both WL and AF conditions. Furthermore, genotypes that had high roots biomass as well as high CLT recorded the lowest reduction in spikelet fertility under WL and AF compared with the low root and low CLT genotype. This study emphasised the relevance of combining water acquisition and CLT for improving field level tolerance of rice to water limitation. Such genotypes recorded significantly higher grain yield under stress as well as well watered conditions. The study led to the identification of promising trait donor genotypes which can be exploited in breeding to develop superior trait pyramided cultivars suitable for semi irrigated aerobic cultivation.
