Background: The availability of macro and micronutrients added to the soil are affected by soil environmental factors leading to various losses. When a similar amount of fertilizer is applied through foliar application, its use efficiency is increased many folds. In the sandy loam soil, foliar applied fertilizers are up to 20 times more effective as compared to soil applied fertilizers. Water soluble fertilizer of 19:19:19 grade N: P: K is totally water soluble and present in crystalline powder form. It can be applied to the crop by fertigation or through foliar spraying. Instant uptake of nutrients by the plants resulting in significant and quick improvement in crop growth. Humic acid when applied to field converted into readily available humic substances which directly or indirectly effect the plant growth. Foliar application of nutrients along with soil application of nutrients increase the yield and to improve the quality of cereal crops .Keeping the aforesaid facts in consideration, the present investigation was carried out to study effect of NPK water soluble fertilizer on growth, yield and yield attributes and nutrient uptake of ragi. Methods: The present investigation was carried out during January – May 2018 at farmers field, kamarajapuram village, Katpadi Taluk, Vellore district, Tamil Nadu, India. The experiments were laid out in RBD (Randomized Block Design), Ragi [Elusine coracana (L.) Gaertn], CO-14 variety were taken into study. The experimental soil was sandy loam, 10 treatments with replicated thrice. The soil and plant sample was collected periodically proceed with standard analytical and statistical method followed. Result: Our investigations the soil and foliar feeding of nutrients along with water soluble fertilizer and humic acid combined treatment T10 (Soil application of 50% RDN + foliar spray of 50% RDN and 100% P and K through water soluble fertilizer [on 20 and 40 DAT] + foliar spray of humic acid 0.1% [on 20 and 40 DAT]) was significantly superior in performance with respect to growth, yield attributes, quality and nutrient uptake by ragi. It can be recommended to farmers to achieve more benefit from finger millet.

Waste generation is a global issue that necessitates effective management for both human and animal health as well as environment. There are several ways to reduce waste, but recycling appears to be the best choice. By recycling, not only will the problem of pollution be resolved, but valuable compounds could be generated to be used as nutrients for plants. In this study, eco-friendly methods were established to produce α- and β-chitosan (CS) (as a source of nitrogen) with different degrees of deacetylation from shrimp shells and squid pin waste, phosphorous through degreasing and calcination of bovine bone and potassium from evaporation of banana peels Kolakhar. The waste bulk products were physically characterized and dry-milled into nano-powders. Different concentrations of the produced nano-NPK fertilizer (10%, 25%, 50% and 100%) were foliar-applied to Capsicum annum L. cv. Cordoba plants and compared to commercial chemical fertilizer and untreated control plants. The obtained results revealed that the nano-composite NPK with 25% concentration significantly promoted growth, yield and harvest of C. annuum as compared with the control and chemical fertilizer-treated plants. This study demonstrated that the use of an eco-friendly preparation of waste NPK composites, with a low concentration, could be applied as foliar fertilizer over chemical fertilizer to enhance the growth and productivity of Capsicum.

Clinoptilolite Zeolite

Papaya cultivation on nutrient deficient acidic peat soils causes poor growth, yield, and fruit quality of this crop. Alkalinity and the high affinity of clinoptilolite zeolite (CZ) for macronutrients could improve pH, nutrient availability, and papaya productivity on peat soils. A one-year field experiment was conducted to determine the effects of CZ on: (i) soil ammonium, nitrate, P, and K, and (ii) growth, yield, and fruit quality of papaya grown on a peat soil. Treatments evaluated were: (i) different amounts of CZ (25%, 50%, 70%, and 100% of the existing recommended rate of CZ) + NPK fertilizer, and (ii) NPK fertilizer alone. The peat soils with CZ improved pH, ammonium, nitrate, P, and K availability because of the sorption of these nutrients within the structured framework of the CZ. Co-applying CZ (70% to 100%) and NPK fertilizers improved the NPK contents in papaya leaves and the growth, yield, and fruit quality of papaya because of the significant availability of ammonium, nitrate, P, and K in the peat soil for their optimum uptake by the papaya plants. Ability of CZ to buffer the soil pH reduced the need for liming. It is possible to use CZ to improve papaya productivity because CZ can regulate nutrient availability.

The study was conducted on sandy loam soil at IAAS Rampur, Chitwan during May to September, 2012 to evaluate the effect of different combinations of biogas slurry and urea on production of okra, laid out in a two-factor RCBD with three replications. Altogether ten treatments consist of two varieties namely Arka Anamika - open pollinated and Jaikisan-62-F1 hybrid and four different levels of biogas slurry and urea combination (urea75%+biogas slurry25%, urea50%+biogas slurry50%, urea25%+biogas slurry75% and biogas slurry100%) and only inorganic chemical (75:60:50 kg NPK/ha) as control. All treatments were based on fulfillment of required nitrogen for the crop. The results showed that application of urea50%+biogas slurry50% increased plant height, leaf area, number of leaves and number of nodes at final harvesting. Treatment urea50% + biogas slurry50% allow maximum number of pickings/plant (23.2) and number of fruits/plant (23.5) resulting highest yield/plant (376.3 g). Among the varieties, Jaikisan-62 is superior in terms of growth, yield and post harvest character than Arka Anamika. The net return (Rs. 474,136/ha) and mean B/C ratio was highest (2.59) in Jaikisan-62 treated with urea50%+biogas slurry50%. So, for the commercial production hybrid variety is suggested.

Pathogenicity Tests

Two hundred twenty-seven isolates of Magnaporthe grisea isolated from blast-infected rice tissues from different states of India were tested with MAT1-1 and MAT1-2 fertile standard testers to determine their mating type. Of the 227 monoconidial isolates, 90 (39.6%) were fertile and 137 (60.4%) were infertile and did not produce perithecia when mated with any of the four testers. In the states of Meghalaya and Himachal Pradesh, both mating types were found. In the states of Andaman Islands, Andhra Pradesh, Karnataka, Haryana, and Punjab, only mating type MAT1-1 was identified. In states where MAT1-2 occurred, its frequency was low. Among the 90 fertile isolates, 40 (44.4%) produced perithecia, asci, and ascospores, and 11 of those isolates produced perithecia, asci, and ascospores with both MAT1-2 testers, KA-9 of finger millet, and GUY11 of rice origin. However, when monoconidial isolates were mated among themselves, isolates from the same field produced only barren perithecia. Pathogenicity tests of the ascospore progeny derived from crosses of field isolates and host-specific testers revealed that none of the ascospore progeny were as virulent as the parents, despite showing compatible reactions with both rice and finger millet cultivars. These results indicate that recombinant progeny may be at a selective disadvantage despite having an increased host range. This is the first report of the occurrence of high levels of fertility (24 to 52%) in rice isolates of M. grisea in different states of India. In a Southern blot analysis, 58% of 74 isolates were identified as MAT1-1 and 41% as MAT1-2. In this population, 23 Magnaporthe grisea repeat (MGR)-restriction fragment length polymorphism groups or lineages were identified. In terms of lineage composition, the 18 isolates from Meghalaya showed maximal diversity with nine lineages.
