A field experiment was carried out Rabi season of 2017-18 at research farm of ICAR-NRCSS, Ajmer, Rajasthan to study the growth, yield and essential oil characterization of coriander variety Ajmer Coriander-2 (ACr-2) as influenced by nutrient levels and crop geometry. The experiment was laid out in Factorial Randomized Block Design with four replications. The experiment was comprises three treatment of each crop geometry and nutrient management. Crop geometry G1 (30 cm x 15 cm), G2 (30 cm x 10 cm) and G3 (30 cm x 5 cm) with nutrient levels N, P2O5 and K2O of kg/ha F1 (40:20:10), F2 (50:25:15) and F3 (60:30:20). The results revealed that the maximum plant height (91.38 cm), primary branches per plant (10.90) and secondary branches per plant (13.28) were recorded with application of 60:30:20 kg/ha NPK and crop geometry of 30 cm x 10 cm. Similar trends were found in yield attributes like number of umbel per plant (34.09) and number of umbellates per umbel (5.91). Seed yield per hectare (1271.25 kg/ha) and essential oil yield (6.74 kg/ha) was also observed with application of 60:30:20 kg/ha NPK with crop geometry of 30 cm x 10 cm. Based on the results it is concluded that nutritional level of 60:30:20 kg/ha NPK with crop geometry of 30 cm x 10 cm is better for realizing higher seed yields of coriander variety ACr-2.
A field study was carried out to assess the effect of different organic manures (Vermi-compost, sheep manure and farmyard manure) and Rhizobium inoculation on yield and uptake of nutrients in fenugreek (Trigonella foenumgraecum L.) and soil properties during 2011-12 and 2012-13. Result revealed that yield of fenugreek enhanced by the application of organic manures and seed inoculation with Rhizobium. However, yield obtained with farmyard manure was highest as compared to other inputs and control. The per cent yield increased with these manures and Rhizobium was 11.45, 20.83, 22.22 and 35.42 with Rhizobium, sheep manure, vermi-compost and FYM, respectively. Chlorophyllcontent and uptake of macro and micronutrients in fenugreek and soil available macronutrients were more with FYM. Total chlorophyll content was more at 90 days followed by 30 and 60 days. Uptake pattern of nutrient indicated that N, K, Fe, Mn and Cu accumulation was more in straw than seed. Contrary to it, P and Zn accumulation was more in seed than straw. Straw yield and availability of micronutrients except Mn did not influence either by manures orseed inoculation with Rhizobium. Soil organic carbon was only higher with sheep manure and FYM. Regardless, it has been cited in some of the literature that vermi-compost is always better than any other farm manures, however our results are warranted. The nutritional value of FYM was the best and vermi-compost was found poorest among the commercially available manures used in this study.
Integrated nutrient management refers to maintenance of the soil fertility and plant nutrient supply to an optimum level for sustaining the desired crop productivity through optimization of the benefits from all possible sources of plant nutrient in an integrated manner. Therefore, it is a holistic approach, where we first know what exactly is required by the plant for an optimum level of production, in what different forms these nutrients should be applied in soil and at what different timings in the best possible method and how best these form should be integrated to obtain highest productive efficiency on the economically acceptable limits in an environment friendly manner. To identify suitable integration of different sources of nutrients in different ratios with respect to vegetative growth, fruit yield and quality, a field investigation was carried out on integrated nutrient management in acid lime (Citrus aurantifolia Swingle) in randomized block design with three replications. There were nine treatments, T 1-Control (500 : 300 : 300 g NPK per tree through fertilizers), T 2-2/3 RDF + 1/3 through Goat manure, T 3-2/3 RDF + 1/3 through Neem Cake, T 4-1/3 RDF + 2/3 through Goat manure, T 5-1/3 RDF + 2/3 through Neem Cake, T 6-50% RDF + 50% through Goat manure, T 7-50% RDF + 50% through Neem Cake, T 8-100% RDF as Goat manure, T 9-100% RDF as Neem Cake. The observation on growth parameters of acid lime tree, fruit yield and yield attributes and fruit quality were recorded to study the effect of treatments and their interpretation. Results of the investigation revealed that treatment T 6 (50% RDF + 50% through goat manure) performed best among all treatments. The maximum vegetative growth and yield (7.58 kg tree-1) of fruits having highest fruit length (4.43 cm), fruit diameter (3.99 cm) and fruit weight (35.71 g) was recorded under T 6 treatment. Similarly best quality fruits were also produced with maximum juice (43.37%), TSS (10.42%) and Ascorbic acid (86.33 mg/100 g juice) content and minimum seed (1.15%) and acidity (6.06%) content under the same treatment.
