This study consists in looking for an improvement of Archachatina margina reproductions performances by amendment of the breeding substrates. As a result, five types of substrate were prepared by soil amendment at different rates (0%, 10%, 20%, 30% et 40%) with chicken egg shell powder. On these substrates, snails were raised from spat stage until they were laid. Reproductive parameters such as: age of first laying, the number of annual laying per animal, the number of eggs per laying on the different substrates were recorded. Overall, snail laying performances improved with increasing rate of substrate amendment. However, beyond a rate of 20%, the weight of eggs laid began to decline. The chicken egg shell powder is suitable for the amendment of the breeding substrate of snails Archachatina marginata in view of an improvement in their reproductive performance. The rate of amendment recommended to this effect is 20%.

In 2001, BRRI dhan-3l had about 10-15% higher plant height, very similar tillers/plant, 15-25% higher leaf area at all days after transplanting (DAT) compared to Sonarbangla-1. Sonarbangla- 1 had about 40% higher dry matter production at 25 DAT but had very similar dry matter production at 50 and 75 DAT, 4-11% higher rooting depth at all DATs, about 22% higher root dry weight at 25 DAT, but 5-10% lower root dry weight at 50 and 75 DAT compared to BRRI dhan-31. The photosynthetic rate was higher (20 μ mol m-2/sec-1) in BRRI dhan-3l at 35 DAT (maximum tillering stage) but at 65 DAT, Sonarbangla-l had higher photosynthetic rate of 19.5 μ mol m-2 sec-1. BRRI dhan-3l had higher panicles/plant than Sonarbangla-1, but Sonarbangla-1 had higher number of grains/panicle, 1000-grain weight and grain yield than BRRI dhan-31. In 2002, BRRI dhan-31 had the highest plant height at 25 DAT, but at 75 DAT, BRRI hybrid dhan-l had the highest plant height. Sonarbangla-1 had the largest leaf area at 25 and 50 DAT followed by BRRI dhan-31, but at 75 DAT, BRRI dhan-31 had the largest leaf area. The highest shoot dry matter was observed in BRRI dhan-31 followed by Sonarbangla-1 at all DATs. Sonarbangla-1 had the highest rooting depth and root dry weight at all DATs. BRRI dhan-31 gave the highest number of panicles/plant followed by Sonarbangla-I, BRRI hybrid dhan-l had the highest grains/panicle followed by BRRI dhan-31 and Sonarbangla-I had the highest 1000-grain weight followed by BRRI dhan-31. The highest amount of grains/plant (34.6 g) was obtained from BRRI dhan-31. Key Words: Shoot dry matter; root dry weight; leaf area; photosynthesis; grain yield.

Aim: Amelioration effect of soil amendment on growth and yield of Vigna unguiculata L. grown in acidic and alkaline soils. Study Design: The study was conducted in a randomized complete block design with five replicates. Place and Duration of Study: Department of Botany, University of Calabar, Nigeria, between May and September, 2017. Methodology: Composite soils from two locations Akamkpa (pH 4.0) and Odukpani (pH 9.0) were collected, mixed thoroughly with organic manure (OM) and agricultural lime (AL) singly and in combination, allowed to stay three weeks for proper blending before V. unguiculata seeds were sown. On seedlings germination, amelioration effect of soil amendment on growth and yield of cowpea grown in acidic and alkaline soils was studied at different periods of growth. Results: Results revealed significant (P=0.05) increase in leaf area, plant height, number of leaves, leaf fresh and leaf dry weight, relative growth rate, net assimilation rate and leaf area ratio of V. unguiculata grown in acidic and alkaline soils treated with OM and AL. Pod length, number of pods plant-1, number of seeds pod-1, number of seeds plant-1, weight of 100 seeds increased significantly. Organic manure used singly and in combination was more effective in ameliorating soil pH effect than AL. Vigna unguiculata performed better in treated and untreated alkaline than in acidic soils. Least plant height for V. unguiculata grown in untreated alkaline soil at 12 weeks after sowing WAS was 60.22±0.16a cm and highest 119.63E2±.35g cm for plants grown in soil treated with AL1+OM1. Least number of seeds plant-1 for plants grown in untreated acidic soil at 12 WAS was 90.60±0.02a and the highest 139.18E2±0.02e for plants grown in soil treated with AL1+OM1. Conclusion: An improvement in growth and seed yield of V. unguiculata grown in acidic and alkaline soils is feasible through the use of organic manure and agricultural lime.

AbstractA field experiment was carried out to study the effect of spacing and nitrogen level on growth and yield of maize in Parbat from February to July, 2019. The experiment was laid out in two Factorial Randomized complete Block Design (RCBD) comprising of spacing: 60×15 cm and 60×25 cm and nitrogen: 30, 60, 90 and 120 kg/ha level as treatment with three replications. “Arun-2” variety of maize was planted on clay loam and acidic soil (pH 5.3) having medium in total nitrogen (0.15%), medium in soil available phosphorus (48.1 kg/ha), medium in soil available potassium (218.8 kg/ha) and medium in organic matter content (2.92%). Result shows that yield was significantly increased with increment in N-level up to 90 kg N/ha. The grain yield (5.18 mt/ha) was significantly higher at 90 kg N/ha than at 30 and 60 kg N/ha but at par with 120 kg N/ha. Significant effect on grain yield due to spacing was observed. The grain yield (4.11 mt/ha) obtained at spacing 60×15 cm. Moreover, the highest grain yield showed that highest grain yield (4.33 mt/ha) was obtained under 90 kg N/ha plus 60×15 cm spacing. The result revealed that different spacing and nitrogen level significantly affect the plant height and leaf area index. The plant height and leaf area index were significantly high at close spacing (60×15 cm) and at 120 kg N/ha. Likewise, yield attributing characteristics like cob length, cob diameter, number of kernel/rows, number of kernel row, thousand gran weight were the highest at 90 kg/ha but as par with 120 kg/ha at close spacing (60×15 cm). This study suggested that maize production can be maximized by cultivating “Arun-2” maize fertilizing with 90 kg N/ha and maintaining 60×15 cm spacing.

The yield loss as a result of weed infestation is a major problem in maize fields. Hence, this research meant to examine the impacts of weed chemical control on maize growth and yield. The design of experiment was randomized complete block, and comprised 10 treatments viz., T1 (Control, weedy check), T2 (Weed free), T3 (Atrazine 1.5 kg ha-1 pre-emergence), T4 (Atrazine 750 g ha-1 + Pendimethalin 750 ml ha-1 pre-emergence), T5 (Atrazine 1.5 kg ha-1 followed by 2,4-D amine 0.4 kg ha-1 at 25 days after sowing as Post-emergence), T6 (Halosulfuron 67 g ha-1 at 25 DAS), T7 (Atrazine 1.5 kg ha-1 pre-emergence followed by Halosulfuron 90 g ha-1 25 days after sowing), T8 (Tembotrione 120 g ha-1 Post-emergence at 25 days after sowing), T9 (Pendimethalin 1000 ml ha-1 pre-rise fb Atrazine 750 g ha-1 + 2,4-D amine 0.4 kg ha-1 at 25 days after sowing as Post-emergence) and T10 (Atrazine 1.5 kg ha-1 pre-emergence followed by Tembotrione 120 g ha-1 Post-emergence at 25 days after sowing) with 3 replicates. The results showed that among other treatments, T10 recorded highest number of kernels per row (36.18), number of kernel cob-1 (499.12) and kernel weight cob-1 (136.97 g). A higher plant height (172.19 cm), leaf area (396.6 cm2 plant-1), dry matter accumulation (211.37 g plant-1), kernel yield (6.7 t ha-1) and stover yield (11.6 t ha-1) were found with weed free check plot which is on par with T10 treatment which brought about a higher value of plant height (162.93 cm), dry weight accumulation (205.7 g plant-1), leaf area (384.3 cm2 plant-1), kernel yield (6.5 t ha-1) and stover yield (11.4 t ha-1). In the meantime, T9 treatment reasonably increased kernel yield (6.2 t ha-1) and stover yield (11.0 t ha-1). It shows that application of herbicides as pre-emergence followed by post-emergence, such as T10 treatment could be a good method for weed control in maize fields.
