A field experiment was carried out on cowpea (Vigna unguiculata (L.) variety Kashi Kanchan during summer season at the experimental farm, department of Vegetable Science, College of Horticulture and Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh. The experiment was laid out in factorial complete randomized block design with 12 treatments i.e. three levels of phosphorus [control 0 kg(P0), 20 kg (P1) and 40 kg (P2) /ha] and four levels of bio-fertilizer [control (B0), Rhizobium10 ml/kg seed(B1), PSB 10 ml/kg seed (B2) and Rhizobium + PSB both 10 ml/kg seed (B3)] with three replications. The uniform dose of nitrogen (N) and potassium (K) @ 20 kg/ha along with 10 t/ha FYM (Farm Yard Manure) were applied to all the treatments. Result indicated that the application of P2 (40 kg P/ha) significantly increased the plant height, leaf area index, stem girth, number of nodules per plant, number of branches per plant , total dry matter, pod yield, available soil nutrient status viz., pH, N, P, K, organic carbon and NPK content in plant after harvesting. Similarly, seed inoculation with B3 (Rhizobium + PSB) significantly enhanced the growth, yield, soil nutrient status and nutrient content in plant over single inoculation of Rhizobium and PSB. Combined inoculation of seed with Rhizobium + PSB (B3) along with 40 kg P/ha (P2) significantly increased the stem girth (1.84 cm), total dry matter (13.91g/plant), green pod yield (196.37g/plant and 120.90q/ha), soil nutrient status viz., pH(6.20), available N (370.89 kg/ha), available P (38.57 kg/ha), available K (168.77 kg/ha), organic carbon (2.80%) and N, P and K (0.17%, 0.16% and 0.39%) content over rest of treatment combination.

Background: Cowpea [Vigna unguiculata (L.) Walp] is the most widely cultivated pulse crop of Kerala. Deficiencies of micronutrients viz., Zn and B are a common problem in cowpea. Foliar nutrition is very effective to correct the micronutrient deficiencies in pulses but it is too laborious. Seed pelleting and priming are two simple cost-effective methods to overcome the micronutrient deficiencies. The present study aimed to study the effect of seed invigouration with zinc sulphate and borax and to evaluate its effect along with Trichoderma viride on nutrient uptake and soil nutrient status of grain cowpea.Methods: The experiment was conducted at Coconut Research Station, Balaramapuram, Thiruvananthapuram, Kerala. The experiment was conducted in RBD with 8 seed invigouration treatments and a control during Rabi 2018.Result: Seed invigouration treatments had significant effect on nutrient uptake and nutrient availability. Seeds primed in ZnSO4 0.05 per cent for 4h recorded the highest NPK uptake by crop, the highest soil organic carbon content, available N and Zn status. Zinc uptake by crop and available soil K status were recorded the highest in seed primed in ZnSO4 0.05 per cent for 4h + Trichoderma viride seed treatment 10 g kg-1 seed. Boron uptake by crop and available soil B and P status were recorded the highest in seeds pelleted with borax 100 mg kg-1 seed. Hence it can be concluded that seed primed in ZnSO4 with 0.05 per cent for 4 h improved the Zn availability and uptake and seed pelleting with borax 100 mg kg-1 improved the B availability and uptake of grain cowpea.

Field experiments were conducted on Alfisols in Nigeria between 1991 and 1993 to determine the residual effect of maize (Zea mays) and cowpea (Vigna unguiculata) on the growth, pod yield and N response of a succeeding okra (Abelmoschus esculentus) crop. Cowpea and maize were grown alone with 30 and 60 kg/ha of N, P and K, respectively, or intercropped with 60 kg/ha as a basal dressing. The preceding crops had a significant effect on soil nutrient changes, okra growth and yield, and N response of okra. Cowpea increased the N, P and K status of the soil in both sole and mixed stands, compared with sole maize. Leaf area, pod weight and marketable pod yield of okra after sole cowpea or the maize/cowpea intercrop were all significantly higher than after sole maize. Although the application of nitrogen to succeeding okra promoted growth and increased pod yield, this was not accompanied by an increase in the pod yield of okra after sole cowpea or the maize/cowpea treatment beyond 45 kg N/ha. The beneficial effects of the preceding maize/cowpea intercrop on soil fertility, okra pod yield and amounts of N required for okra were partly due to the higher rate of basal nutrients applied as compared to the effects following sole cowpea.

In the North Western Himalayas, particularly Jammu region, where 85% of people depend on agriculture and allied sectors, 70% of agriculture is rain-fed. Various factors, especially land use pattern and variations in climatic conditions affect the soil fertility and nutrient contents. However, information on essential nutrients in the soil across the region is meager. An attempt has been made to study the soil nutrient status under different agro-climatic zones of Jammu region. Seven hundred seventy surface soil samples (0-15 cm) from sub-tropical, intermediate and temperate zones of Jammu region were collected and analyzed for soil texture, pH, electrical conductivity (EC), organic carbon (OC), CaCO3, CEC, available macro nutrients (N, P, K, S) and micronutrients (Fe, Cu, Zn, Mn). The results indicated large variation within the soils of each zone. The amount of all the available nutrients was more in the soils of temperate zone than those of other zones. The soils of sub-tropical zones were low in available N, P, S and Zn and to some extent in K. Organic matter content, clay and silt content of the soil vis-à-vis cation exchange capacity were found to be the main factors controlling the available nutrient content of the studied soils.

Birbhum District

A GPS based soil sampling and testing was done in 10 blocks of Birbhum district under monitoring of Rathindra Krishi Vigyan Kendra, Birbhum during 2018 and 2019. In this regard, some soil chemical properties were analysed through Mridaparikshak (soil testing kit). After statistical analysis, pooled data of different soil nutrients were compared based on GPS to prepare a data base for easy fertiliser recommendation of different crops without soil testing. It was found that soil pH (6.29 to 5.50), soil O.C (0.77 to 0.31%), available K (292.12 to 226.60 kg/ha), available B (0.81 to 0.17 mg/kg)  and available Fe (44.4 to 21.5 mg/kg) had been decreased with the increase in latitude from 23°04' 07.4500" to 24°11' 15.3400" and longitude. Recommendation of more liming, organic manure, K, B may be done accordingly. On the other hand, available N (184.0 to 296.95 kg/ha), available P (15.05 to 62.76 kg/ha), available S (11.43 to 44.52 kg/ha) and available Zn (0.20 to 1.04 mg/kg) showed sharp direct relation with the increase in Latitude as supported by higher CV value.

Pods and seed of all annual legume species and a soil sample were collected within a 1 m2 sample area at each of 161 sites in Morocco, and the surrounding area of approximately 0.5 ha intensively searched for all species. This paper reports findings for all genera except Medicago and Trifolium which are the subject of separate papers. Annual legumes were found at 138 sites and 15 genera and 31 species were identified. Scorpiurus sulcata, the most prolific species, was found at 117 sites, followed by Astragalus hamosus (52 sites) and Hippocrepis unisiliquosa (30 sites). The distribution of the genera was related to pH, sand and clay content, altitude and rainfall, but very little to soil nutrient status. The highest pod yield was 890 kg/ha for Scorpiurus sulcata whilst Hedysarum coronarium had the highest average pod yield of 392 kg/ha but occurred at only 3 sites. Scorpiurus had the highest average pod yield of any genus that occurred at more than just a few sites. Overall pod yields were strongly related to sand and clay content of the soil, rainfall and minimum temperature and to a lesser extent, to altitude and soil potash. The most significant finding was the widespread distribution of Scorpiurus sulcata which did not appear to have any specific requirements for soil type, soil nutrient status, altitude or climate. The need to assess Scorpiurus sulcata as a potential pasture plant for Morocco and other areas of similar climate is clearly indicated.

Variety and sulphur play a significant role in the physiological growth and yield of crops such as groundnut. Even so, there has been little information on the application of variety and sulphur in groundnut. Therefore, an experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University (BAU), Mymensingh to investigate the effect of sulphur on yield and yield components of two groundnut varieties. The experiment comprised two varieties of groundnut viz. BARI Cheenabadam-8 and Bina cheenabadam-6; and five levels of sulphur viz. 0, 15, 30, 45, and 60 kg ha–1. The experiment was laid out in a randomized complete block design with three replications. Among the parameters leaf area index  (2.03), dry matter plant–1 (50.36 g),  number of primary branches plant–1 (10.33 cm), number of secondary branches plant–1 (9.27 cm), number of pegs plant–1 (46.27), number of total pods plant–1 (37.80), 100-pods weight (96.82 g), 100- seeds weight (46.25 g), shelling percentage (85.29%), pod yield (3.13 t ha–1), seed yield  (2.67 t ha–1), stover yield (6.84 t ha–1), and harvest index (31.37 %) were the highest  in BARI Cheenabadam-8, when treated with sulphur 60 kg ha–1. The lowest values of all these parameters were found in Binacheenabadam-6, when no sulphur was applied. This study suggested that BARI Cheenabadam-8 combined with sulphur 60 kg ha–1 could be applied for obtaining the highest yield of groundnut. J. Bangladesh Agril. Univ. 17(1): 1–8, March 2019
