“…In their study, to emphasize the importance of the N starter dose on the legume crop growth and development, ref. [54] stated that in the early growth stages the legume crop relies mainly on N in seeds and soil fulfilling its requirements until the seedling stage, whereas, in later growth stages, N requirements are fulfilled mainly from biological N fixation. Therefore, deficiency of N in the soil in the seedling stage and/or limited biological N fixation at later stages might induce N deficiency symptoms on the legume plant.…”

Intercropping maize and forage cowpea is a widely proposed strategy to improve land use efficiency, and maximize the economic value of the farming system, especially in developing countries with restricted resources. The current study was carried out during the successive summers of 2020 and 2021 in Northern Egypt. The main objective was to evaluate the effect of three N schedules (NS1, NS2, NS3), when three different maize–cowpea intercropping patterns (IP1, IP2, IP3) were applied, on the grain yield of maize, forage yield and quality of forage cowpea. In addition, yield gain and land use efficiency were evaluated using the land equivalent ratio (LER) and dry matter equivalent ratio (DMER) indices. Results revealed that the intercropping patterns that provided wider spacings for the component crops and reduced the competition between them, mainly IP3, resulted in the best performances for the two crops. This was clear for maize ear and grain yields, 100-grain weight and harvest index, in addition to cowpea fresh and dry forage yields, crude protein and non-fiber carbohydrates of the three cuts. Regarding the applied N schedules, NS1 which included the application of a N starter dose with sowing proved to be the most efficient schedule that led to the best performance for both crops. Maize produced 9.07 t ha−1 grain yield under IP3 and NS1. In addition, the application of IP3 resulted in the highest significant cowpea dry forage yield (DFY), with the highest crude protein (CP) content. The DFY of cuts 1, 2, and 3 amounted to 1.27, 0.45, and 0.24 t ha−1, while the CP content for the three respective cuts reached 159.49, 157.96, and 148.91 g kg−1. Nonetheless, NS1 produced a reasonable amount of DFY with high CP content. It is recommended to follow the third proposed intercropping pattern (IP3) and to include a nitrogen starter dose (NS1) in the fertilization scheme to ensure highest productivity from the intercropped maize and forage cowpea.

“…Nitrogen occurs primarily in the plant as component of protein. Generally, the soil containing higher nitrogen increases grain protein ratios so that application of N fertilizer, especially in the soil with a low level of nitrogen, could increase grain protein content (Dar et al, 2016). Our results revealed that inoculation and nitrogen application supplied together or separately to chickpea increased grain protein content.…”

“…The results of various researches have shown that chickpea usually can tolerate low fertilizer input, and has illustrated different growth patterns and responses to nitrogen application. Many authors reported that nitrogen fertilizer application had significant effects on morphological and physiological traits of chickpea (David and Khan, 2001;Salvagiotti et al, 2008;Glyan'ko et al, 2009;Dar et al, 2016). Some researchers argue that before the symbiosis becomes fully functional, it is required to apply nitrogen fertilizers to legume crops so as to provide adequate amount of N for the young plants.…”

To evaluate the effects of nitrogen fertilizer and inoculation with arbuscular mycorrhiza and Rhizobium ciceri on grain quality of chickpea, two experiments were conducted. The greenhouse experiment was designed as randomized complete blocks (RCB) in a factorial arrangement with four replications. The first factor consisted of two seedbeds including S 1 (field soil) and S 2 (soil + organic fertilizers). The second factor included inoculation with rhizobium, mycorrhiza, combined rhizobium and mycorrhiza, and control. The results showed that combined inoculation in S 2 increased plant height, root dry matter, shoot dry matter, and leaf chlorophyll content by 23.5, 27.2, 60, and 41.3%, respectively compared with control and it was selected for the next experiment as the best inoculant. In the field experiment, treatments included two inoculation levels (noninoculated and combined inoculation) and split application of nitrogen fertilizer during sowing, flowering, and pod filling including F 0 (0 kg, 0 kg, 0 kg), F 1 (25 kg, 0 kg, 0 kg), F 2 (25 kg, 25 kg, 0 kg), F 3 (25 kg, 25 kg, 25 kg), F 4 (50 kg, 0 kg, 0 kg), F 5 (50 kg, 50 kg, 0 kg), and F 6 (50 kg, 50 kg, 50 kg), respectively. The results showed that application of nitrogen fertilizer increased grain nitrogen, phosphorus, fiber, and protein content compared with unfertilized treatment (F 0 ) but did not affect P, K, Fe, Zn, and starch content. Also, combined inoculation increased grain N, P, K, Zn, Fe, and protein content by 18.7, 7.6, 7, 9.7, 10.4, and 11.2%, respectively, compared with control. In general, the split application of N fertilizer (especially F 3 and F 6 treatments) and coinoculation with effective rhizobacteria and arbuscular mycorrhiza fungi increased nutrient content and the quality of chickpea grain.

“…Accumulations of these activities have led to the reduction of soil N to about 0.12% of the average plant requirement in semi-arid regions of Kenya (Wafula et al 2021). Although chickpea can fix nitrogen (N), soils with N deficiency require small doses of starter N-fertilizer at planting time to promote early growth (Lemma et al 2013;Dar et al 2021). Thus, legumes also need N-fertilizer application to boost their productivity (Li et al 2016).…”

Chickpea is a pulse crop that is rich in proteins and helps in fulfilling the requirement of protein for vegetarian people thus yield maximization needed. This study aimed to determine the effects of spacing, nitrogen rates, and their interactive effects on the growth and productivity of the selected chickpea varieties. Field experiments were conducted at Mwea, Kenya between 2017 and 2018 involving four varieties (Saina K, Mwanza 2, Chaina I and Chaina III) at a spacing of 50x10cm, 50x20cm, and 50x30cm, and starter nitrogen-fertilizer application rates 0kg, 30kg, 60kg, and 90kg ha-1. A split-split plot design arranged in a 4x3x4 layout was used in the current study. Data related to plant height, biomass, grain yield, and harvest index were collected and subjected to statistical analysis by GLM in SAS 9.4 computer software. Variations occurred in measured traits like the height of crops (34.81-38.00cm), biomass yield (3.31 - 8.08t ha-1), seed yield (0.14 to 1.9t ha-1), and percent harvest index (5 - 45%) was reported. Mwanza 2 expressed the highest plant height, biomass, and grain yield. The highest plant biomass was obtained under 50x10cm spacing, while the highest grain yield weight was reported under 50x30cm spacing x 60kg N ha-1. From the results of the study, it can be concluded that the highest enhanced growth and productivity of chickpea were realized at interactions of Mwanza 2x50x10cmx90kg ha-1 nitrogen rate in the study area.
