Background: Zn deficiency was predominant in soils of Chittoor district of Andhra Pradesh, which causes yield reduction in most of the crops especially in finger millet. Zinc has important role in enzyme activation viz., oxidoreductase, transferases, hydrolases, lyases, isomerases and ligases. The deficient soil gives us the zinc deficient food which is said to be the major root cause for malnutrition among the children. Hence present study was intended to find out most appropriate method and time of zinc fertilization for higher productivity, grain quality and zinc fortification with two major finger millet varieties viz., vakula and tirumala. Methods: The field experiment was laid out in split plot design with three replications and two varieties viz., vakula (V1) and tirumala (V2) with seven zinc application treatments which includes: control (T1); NPK (30-30-20) + FYM @ 10t ha-1 (T2); T2 + soil application (SA) of ZnSO4 @ 25 kg ha-1 as basal (T3); T2 + SA of chelated zinc sulphate @ 5 kg ha-1 as basal (T4); T2 + FA of 0.2% ZnSO4 at ear head emergence stage (T5); T2 + foliar application (FA) of 0.2% ZnSO4 at grain filling stage (T6); T2 + FA of 0.2% ZnSO4 at ear head emergence and grain filling stages (T7). Result: Foliar application of 0.2% ZnSO4 at ear head emergence and grain filling stages registered significantly highest grain and straw yield of 3150 kg ha-1 and 7364 kg ha-1, respectively compared to control and other zinc fertilization treatments. Between the two tested varieties tirumala variety recorded higher grain yield (2298 kg ha-1) compared to vakula variety (2230 kg ha-1).

Background: The improvement in livestock productivity may be possible by availing better quality fodder in adequate quantity to the dairy farmers. Zinc deficiency might be a major factor for lower quality fodder of cowpea. Methods: The experiment was laid out in factorial randomized block design; comprised of three cowpea cultivars viz., C-152, MFC-08-14 and MFC-09-1 and five zinc management practices viz., control; 10 kg ZnSO4 as basal; 20 kg ZnSO4 as basal; 0.5% ZnSO4 as foliar spray at 20 DAS; 0.5% ZnSO4 as foliar spray at 20 and 40 DAS. Result: Results revealed that C-152 showed significantly better quality in terms of higher dry matter, crude protein and total ash; and lower acid insoluble ash, neutral detergent fibre, acid detergent fibre and acid detergent lignin amongst all the three varieties. Though, remarkably higher ether extract was obtained with MFC-08-14. Among the zinc management practices, 20 kg ZnSO4 as basal (Zn3) and foliar application of 0.5% ZnSO4 at 20 and 40 DAS (Zn5) recorded significant improvement in fodder yield and quality traits of cowpea.

Aim: To investigate the effect of KCl and KClO3 as sources of potassium in aerobic rice with four types of split doses and two levels of foliar applications of potassium. Study Design: The experiment was laid out in Randomized Block Design with three replications. Place and Duration of Study: Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, Puducherry. Methodology: The rice variety PMK 4 was tested with two sources of potassium viz., Potassium chloride (KCl) and Potassium chlorate (KClO3), four types of split application viz., K control (S1), basal with no split (S2), two splits (S3) and three splits (S4) along with foliar application treatments viz., no foliar (F1) and foliar spray (F2). Results: The results of field experiment revealed that the N availability in soil was more at all stages of crop growth by two and three split doses of potassium. The KClO3 increased the available N status at active and panicle initiation stages. Whereas in flowering stage, the KCl recorded the higher available N status in soil. The nitrogen uptake at active tillering stage and flowering stage was evidently improved with three split doses of potassium. Whereas in panicle initiation stage, the two split doses registered higher N uptake. The nitrogen uptake by both grain and straw was conspicuously higher in three and two split doses of potassium. Conclusion: The split applications tested in this investigation influenced the available N status in soil. Almost in all the stages, three split applications retained more available N in soil. This implies the positive interaction of potassium with nitrogen.

In the last few years, soil deterioration due to excessive application of synthetic agrochemical has become growing concern. Use of organic fertilizer is believed to be able to enhance soil quality. The objective of this experiment was to determine nitrogen, phosphorus, and potassium uptakes by sweet corn as affected by local based liquid organic fertilizer (LOF) under closed agriculture system. The experiment was conducted in Closed Agriculture Production System (CAPS) Research Station in Air Duku Village, Bengkulu, Indonesia from March to June 2015, employing Randomized Completely Block Design with 2 factors. The first factor was 3 sweet corn genotypes, i.e. Talenta, Jambore, and Asian Honey and the second factor was 5 rates of LOF, i.e. 0, 25, 50, 75, and 100 mg l-1, respectively. Each treatment combination was replicated 3 times. Foliar application of LOF was carried out every week at 2-8 weeks after planting (WAP) with total volume of 600 ml per plant. Sweet corn leaves were sampled at the beginning of tassel emergence. The experiment revealed that sweet corn genotype significantly influenced the uptake of nitrogen, but not phosphorus and potassium. It was observed that Asian Honey genotype absorbed highest nitrogen as compared to other genotypes. In addition, increase in rates of LOF significantly raised nitrogen uptake by sweet corn, but not phosphorus and potassium.

Abstract Soil salinity with different harmful effects on plant growth and productivity is one of the main reasons in diminishing biological nitrogen fixation and nitrogen assimilation in legume plants. Molybdate has a key role on nitrogen metabolism of plants and can be has a beneficial effect on it. Thus, this experiment was conducted to evaluate the effects of sodium molybdate spraying (0.2 and 0.4% solutions in water) on nodulation, nitrogen uptake and translocation in soybean plants under different levels of salt stress (0, 5 and 10 dS m−1 NaCl, respectively). Salinity reduced the nodulation, root and shoot growth and special flavonoids content in roots, which are have a key role in nodulation includes, daidzein, genistein, coumestrol and glycitein, also diminished nitrogenase, glutamine synthetase (GS), glutamate dehydrogenase (GDH), glutamine oxoglutarate aminotransferase (GOGAT) and nitrate reductase (NR) activities in nodes, nitrogen content of nodes, roots and leaves, nitrogen uptake and translocation by soybean plants. Under salt stress and nonsaline condition, sodium molybdate treatments improved the nodulation by increasing flavonoids content of roots, also these treatments enhanced the plant growth and nitrogenase, GS, GDH, GOGAT and NR activities of nodes. Furthermore, nitrogen content of nodes, roots and leaves, nitrogen uptake and translocation by soybean plants improved by sodium molybdate applications. Both of the sodium molybdate doses, exposed the similar effects on improving nodulation and nitrogen metabolism of soybean.

Among the micronutrients, zinc deficiency is widespread throughout the world particularly in low land rice fields causing low yields and affecting nutritional quality of the produce. In present investigation, 26 rice cultivars including some locals, aromatics, HYVs and hybrids grown on an Inceptisols with no Zn, basal Zn and soil+foliar applied Zn were evaluated for agro-morphological and quality parameters in a strip plot design having three replications during kharif season for consecutive two years (2009 and 2010). Rice cultivars differed significantly in their native agro-morphological parameters as well as among cultivar categories. Grain and straw yield as well as harvest index of different cultivars showed wide variations both with and without Zn application. On average, grain yields of different rice cultivars increased by 29% and 22% with soil plus foliar and only soil application of Zn, respectively. Regarding yield efficiency, HYV showed highest efficiency followed by hybrid, aromatic and local cultivars, irrespective of Zn fertilization. Applications of Zn, both as basal and as soil+foliar application significantly reduced the Fe content in brown rice irrespective of the cultivar grown.
