Cropping Sequence

A field experiment was conducted at Zonal Agricultural Research Station, VC Farm, Mandya during kharif 2017, summer 2018, kharif 2018 and summer 2019 to study the effect of rock phosphate enriched compost on soil nutrient status after harvest of finger millet-cowpea cropping sequence. Prior to initiation of the field experiment, three different composts viz., urban solid waste compost (USWC), vermicompost and farm yard manure (FYM) were enriched with rock phosphate at 5 per cent. Field experiment consisting of eleven treatment combinations comprising recommended N and K, and P through varied levels of enriched composts. The experiment was laid out in RCBD design with three replications and the test crops were finger millet and cowpea. The initial P2O5 of the experimental site was very high (133.58 kg ha-1). The results revealed that application of recommended N and K + 75 per cent P supplied through enriched USWC (T5) had significantly higher organic carbon (0.56 and 0.58%) in pooled data of both finger millet and cowpea, respectively. Available N (241.94 and 224.86 kg ha-1), P2O5 (138.69 and 120.99 kg ha-1) and K2O (153.92 and 135.31 kg ha-1) were recorded significantly higher in T5 of finger millet and cowpea, respectively. Similarly, in pooled mean, exchangeable Ca [4.15 and 4.04 C mol (P+) kg-1] and Mg [2.16 and 2.05 C mol (P+) kg-1] were recorded significantly higher in treatment which received recommended N and K + 75 per cent P supplied through enriched vermicompost (T8) in both finger millet and cowpea, respectively. The decrease of available P2O5 was 20.98 per cent from initial (133.58 kg ha-1) to final crop (summer 2019) (105.55 kg ha-1).

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.

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.

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.

Detailed knowledge of the soil nutrient status is required in site-specific crop production systems. Moreover, the vertical distribution of plant nutrients is most important for plant production. Therefore, the study was conducted to assess the depth-wise soil fertility status of low and mid hill zones of Himachal Pradesh based on thirty-one (31)soil profiles. Geo-referenced depth-wise soil samples were collected. These thirty-one (31) soils sampling sites were selected to represent the cultivated soils (Entisols, Alfisolsand Inceptisols) under major land-use systemsof low and mid-hill zones of Himachal Pradesh. The results of the soil nutrient status revealed that low to medium content of available N, P and S, low to medium content of available K except fewsubsurface horizons in Inceptisolswas found in most of the soils of low hill zone. Under different land-use systems in mid-hill zone, medium to high content of available N and K, low to medium of available P, low to high of available Swas found in most of the soils. Generally, surface soils had a higher mean values of N, P, S, Cu and Zn and lower values of K, Ca, Mg, Fe and Mn. Alfisols had higher value of all the nutrients as compared to Entisols and Inceptisols.

Sowing Dates

A field experiment was conducted during kharif, 2005 at Agricultural Research station, Devihosur, Haveri, Karnataka to assess the progress of powdery mildew at different time interval of sowing dates. Totally 20 different dates of sowings were imposed in the experiment at an interval of 10 days. The crop sown on last week of May to mid of June recorded minimum disease severity compared to rest of the date of sowings. This clearly indicated that crop sown during this period suffers less, which may be due to low inoculum potential, whereas late sown crop suffers more because of the readily available inoculum in the early sown crops. Low disease severity in last week of May to mid of June sowing may be attributed to the non-congenial weather factors for the development of the disease.
