A field experiment was carried out at El-Kod Agricultural Research Station, Abyan Delta, Abyan Governorate during the seasons 2014 and 2015 in soil sandy silt to assess four levels of nitrogen fertilizers (0, 55, 110 and 165 kg N/ha) utilizing urea fertilizer (46% N) on some crop characteristics and efficiency of nitrogen application on two local cultivars of sorghum (Sorghum bicolor L. Moench). Split plot design was applied in four replicates. Fertilizer levels were distributed in main plots whereas, the cultivars in subplots. The results revealed significant differences between cultivars Benny and Saif in all characteristics during the two seasons. Cultivar Benny was significantly superior to cultivar Saif in all crop characteristics, except the length of spike which was significantly superior in Saif cultivar compared to cultivar Benny in both seasons. The increase in nitrogen level led to significant increase in all parameters of crop growth under study in both seasons, where the highest dose of nitrogen (165 kg N/ha) gave highest grain yield (3013 and 3201 kg/ha) in both seasons respectively, while the efficiency of nitrogen utilization declined with increased level of nitrogen application and highest value in nitrogen efficiency (12.78 kg grain/kg N). The interaction between cultivars and nitrogen fertilizer showed significant differences in terms of all studied parameters during both seasons. The cultivar Benny responded to high level of nitrogen (165 kg N/ha) and gave high grain yield (3640 and 3305 kg/ha) in both seasons respectively. The results yielded significant effect for efficiency of nitrogen application on grain yield between the cultivars, the levels of fertilizers and their interaction in the first season whereas, no significant differences were detected in the second season.

Abstract To evaluate the interaction effects of planting date and different levels of nitrogen fertilizer on sorghum (Sorghum bicolor var. Speed feed) forage production, an experiment was conducted in split plots based on a complete randomized block design in Agricultural Research Station of Khorramabad, Lorestan province, Iran. The experimental treatments comprised of three nitrogen fertilizer levels of control (N0), 100 (N1), and 150 kg per hectare (N2), assigned to main plots and three sowing dates of T1 (June, 10th), T2 (June 26th) and T3 (July 11th) assigned to subplots. Results showed that in sum of two harvests, the yield of hay, forage, leaf and shoot hay weigh in second planting date and N2 and N3 level of fertility was higher than all treatments. In the case of quality treatments the percent of crude protein in first harvest had the most amounts in first and second planting date and N1, N2 and N3 fertility levels. Crude fiber percentage in first harvest of second planting date was highest in N1, N2 and N3 levels of fertility. Treatment interactions had not any significant effect for crude fiber. The most ash percent was observed in first harvest and N1, N2 and N3 fertility level. In second harvest time N2 and N3 fertility levels were superior to the rest. Also, fat percentage in first and second planting date and N1, N2 and N3 increased than the control fertility treatment.

Direct seeded rice is a boon to farmers where the water release from the reservoir is delayed. Nitrogen fertiliser management is one of the strategies bto rectify the nutrient-related issue in Direct seeded rice. The present study aimed to optimize the nitrogen dose for direct-seeded rice in the new and old Cauvery delta zone of Tamil Nadu. Field experiments were conducted during kuruvai and samba seasons at Tamil Nadu Rice Research Institute, Aduthurai and Agricultural research station Thanjavur representing old and new Cauvery delta regions during 2019-20 and 2020-21. Totally from eight experiments, the results of four field experiments in each location revealed the highest grain yield in the treatment T6 -application of 150 kg Nha-1 (5596kg/ha) which was statistically on par with treatment T5 -125kg N/ha (5326 kg/ha) in old delta and new delta. The higher grain yield was recorded in the T6 (5140 kg/ha), statistically on par with T5 (4550 kg/ha). The higher available nitrogen content of 312 kg/ ha,292 kg/ha was recorded for N application @ 150kg/ha, which was statistically on par with  309 kg/ha and 289 kg/ha, respectively, both the kuruvai and samba seasons for N application of 125 kg/ha. In the new CDZ, the same trend was followed as that of the old delta. Based on economics, N applied @125 kg/ha recorded a higher BC ratio for direct-seeded rice. For the benefit of farmers of both deltaic regions, the nitrogen application of 125 kg ha-1 for direct-seeded rice is recommended.

Aim: To determine the effect of local rice cultivars and inorganic nitrogen fertilizer on the incidence of stem borer, Scirpophaga incertulas (Walker); leaffolder, Cnephalocrocis medinalis (Guenee); and gall midge, Orseolia oryzae (Wood Mason) and on grain yield of rice. Study Design: A field experiment for two consecutive years was carried out in a split-plot arrangement in randomized block design with three replications. Place and duration of the study: Department of Entomology, Agricultural Research Station, Nellore, Andhra Pradesh, India during Kharif, 2013 and 2014. Methodology: The rice cultivars (NLR 20104, NLR 20106, NLR 3135 and NLR 33892) were attributed to experimental main plots and nitrogen levels (40, 80, 120, 160 and 200 kg ha-1) to the sub plots. Observations on incidence of stem borer, gall midge and leaf folder was recorded in randomly selected 10 hills per subplot in replication and percent incidence was calculated. Results: The pest incidence for the treatments with high N rate as 160 and 200 kg/ha was higher (31.43 & 43.86% stem borer, 9.23 & 13.59% leaffolder and 2.75 & 3.00% gall midge, respectively) than that for lower N rate i.e. 40 and 80 kg ha-1 (19.24 & 20.04% stem borer, 7.37 & 7.95% leaffolder and 1.42 & 1.93% gall midge, respectively). Different rice cultivars significantly influenced the leaffolder incidence but not the stem borer and gall midge incidence. The Highest leaffolder incidence (13.44%) was noticed in NLR 20104 cultivar which was followed by NLR 3135 cultivar with 9.64% leaffolder incidence. Gall midge and leaffolder incidence was not significantly influenced by the combined effect of rice cultivar and nitrogen levels; in contrast, interaction effect has a significant influence on stem borer incidence. Significantly lowest stem borer incidence (18.21%) was noticed with NLR 3135 rice cultivar treated with 40 N ha-1, which was statistically on par with the NLR 20106 rice cultivar treated with 40 kg N ha-1 (18.23%) and NLR 20104 rice cultivar treated with 40 kg N ha-1 (19.76%). Among the different cultivarscultivar, NLR 33892 cultivarhad produced significantly highest grain yield (5955 kg ha-1) may be for having higher physiological indices. The highest/optimum grain yield (5726 kg ha-1) produced by plots that received 120 kg N ha-1. Further increase in nitrogen level beyond 120 kg ha-1 did not significantly improve the grain yield. Optimal N rate was revealed to be 120 kg ha-1 for four rice cultivars for reducing the stem borer/leaffolder/gall midge incidence so as to minimize the cost of inputs for pest control measures and for achieving high grain yield. Conclusions: The incremental doses of nitrogen fertilizer significantly enhanced stem borer, leaffolder and gall midge infestation on rice, which further affects the grain yields.

The research work was conducted in Izra’a Research station, which affiliated to the General Commission for Scientific Agricultural Research (GCSAR), during the growing seasons (2016 – 2017; 2017 – 2018), in order to evaluate the response of two durum wheat verities (Douma3 and Cham5) and two bread wheat varieties (Douma4 and Cham6) to Conservation Agriculture (CA) as a full package compared with Conventional Tillage system (CT) under rainfed condition using lentils (Variety Edleb3) in the applied crop rotation. The experiment was laid according to split-split RCBD with three replications. The average of biological yield, grain yield,  rainwater use efficiency and nitrogen use efficiency was significantly higher during the first growing season, under conservation agriculture in the presence of crop rotation, in the variety Douma3 (7466 kg. ha-1, and 4162kg. ha-1, 19.006 kg ha-1 mm-1,  39.62 kg N m-2respectively). The two varieties Douma3 and Cham6 are considered more responsive to conservation agriculture system in the southern region of Syria, because they recorded the highest grain yields (2561, 2385 kg ha-1 respectively) compared with the other studied varieties (Cham5 and Douma4) (1951 and 1724 kg ha-1 respectively). They also exhibited the highest values of both rainwater and nitrogen use efficiency.

SUMMARYSix intercropping systems and four levels of nitrogen were compared at the Indian Agricultural Research Institute, New Delhi, in the summer rainy seasons (July-October) of 1978 and 1979. The maximum increase in sorghum yield was obtained when it was associated with fodder cowpea, followed by association with grain cowpea and greengram. The application of 40, 80 and 120 kg N ha−1 increased sorghum yield by 8.6, 16.1 and 18.2% in 1978 and by 2.9, 8.1 and 14.1% in 1979, respectively, compared with unfertilized sorghum. The nitrogen uptake by sorghum, and by the total system, was greater in sorghum-legume intercropping systems than in sole sorghum. Nitrogen application also increased the nitrogen uptake by sorghum and by the whole system.

Nicosulfuron is an herbicide used in corn crop for controlling weeds, some hybrids are sensitivity to nicosulfuron even more when it is applied near to the application of nitrogen fertilizers. Thus, this study aimed to evaluate the response of sensitive corn hybrids to association of urea and coated urea applied near to nicosulfuron application on V4 corn stage. P 3646 hybrid was the most sensitive, and urea and coated urea applied near to nicosulfuron had significant effect on corn growth for all hybrids. Most hybrids showed high or significant (p < 0.10) correlation coefficients for grain yield, cob length and row per ear. SYN 7341 hybrid was the one that showed better results in grain yield with urea and nicosulfuron combination. Coated urea should not be applied after V8corn stage when nicosulfuron is applied at V4.
