Tidal swampland is potential but negligible land characterized by poor soil fertility. The study aimed to determine the effect of fertilization packages on the growth and yield of Inpara 2 rice in the tidal field. This research was conducted on the tidal field of Mon Mata Village, Krueng Sabee Sub District, Aceh Jaya, from July to November 2018. The study was designed in a Randomized Block Design three treatments, and three plot replications of 10 m x 10 m. The treatments comprised of three fertilization packages, namely: Farmer’s package A (Urea 100 kg ha–1 + SP 36 50 kg ha–1); Package soil nutrient status B (Urea 200 kg ha–1 + SP36 100 kg ha–1 + KCl 50 kg ha–1), and Recommended package C (Urea 200 kg ha–1 + SP36 100 kg ha–1 + KCl 100 kg ha–1 + 1000 kg dolomite ha–1). The experiment showed that all three fertilization packages significantly impacted plant height, panicle length, number of panicles per hill, grain per panicle, and grain yield. The recommended fertilization package C gave the highest yield (5.20 t ha–1), followed by Package B (4.78 t ha–1) and Package A (3.55 t ha–1). The research suggests that Inpara 2 rice and fertilizers, according to the recommendations, are needed to increase rice productivity in tidal fields.

A pot experiment was conducted at the experimental net house of the Department of Soil Science, Sylhet Agricultural University, Sylhet, Bangladesh to observe the effect of fertilizers on yield and nutrient uptake of local aromatic rice varieties during the Aman season of 2015. The experiment was laid out in a Randomized Complete Block Design with three replications. Five local aromatic rice varieties (Kalizira: V1, Muktasail: V2, Nagrasail: V3, Maloti: V4 and Chinigura: V5) and four packages of fertilizers (F1:  Recommended package i.e. 45-10-20-10-0.5 kg ha-1 of N-P-K-S-Zn, F2: 2/3rd of recommended package, F3: 1/3rd of recommended package, and F4: Control) were used. Urea, TSP, MoP, gypsum and ZnSO4 were used as N, P, K, S and Zn source, respectively. According to the treatment, all fertilizers were applied as basal during final pot preparation while urea was applied in two equal splits (one half as basal and another half at 40 DAT). Nutrient content and uptake of the aromatic rice varieties were significantly affected by the application of different fertilizer packages (with few exceptions). Mostly Kalizira (1.10-0.44-2.31-0.67-13.75 g pot-1 of N-P-K-S-Zn) and/or Nagrasail (1.15-0.46-2.70-0.62-11.74 g pot-1 of N-P-K-S-Zn) varieties showed the highest nutrient uptake in grain and straw with recommended package of fertilizers. While in maximum cases Chinigura (0.41-0.16-0.76-0.197-3.17 g pot-1 of N-P-K-S-Zn) was observed to have the lowest with control treatment. In case of post harvest soil nutrient analyses, Kalizira and/or Chinigura variety associated with recommended package of fertilizers showed the highest nutrient status.

Zucchini (Cucurbita pepo L.) is a horticultural crop of great socioeconomic importance in Brazil and in the world. However, inappropriate fertilization management, such as over-fertilization of soils, may become a limiting factor for its development. Thus, the aim of this study was to evaluate the morpho-physiological behavior of zucchini submitted to nitrogen (N) doses applied via soil and foliar application of silicon (Si). The treatments were distributed in split-plot scheme in a randomized block design, with three replications. The plot was formed by silicon levels (0.0 and 6.0 g plant-1) and the subplots constituted by five nitrogen levels (30, 60, 90, 120 and 150 kg ha-1), adding up to 30 experimental units. Gas exchanges and growth parameters were assessed at 35 days after planting. The data were submitted to analysis of variance by the F test and in the cases of significance was performed a polynomial regression analysis for the nitrogen factor and Tukey test for the silicon factor. The supply of Si positively enhances the effects of N on growth characteristics and gas exchanges of zucchini. The simultaneous application of Si and N does not influence the leaf area of zucchini. The N dose of 93.9 kg ha-1 provides greater assimilation of CO2 in zucchini plants under the conditions in which the experiment was performed.

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research experiment was conducted in a farmer’s field at Pudhupalayam, Coimbatore to investigate the effect of foliar application of PPFM, plant growth regulating compounds and nutrients on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2019 (kharif and rabi) season. The treatments include 100% recommended dose of NPK along with foliar application of diammonium phosphate (DAP), brassinolide (Br), salicylic acid (SA) and pink pigmented facultative methylotrophs (PPFM) with different concentration (1%, 2%, 1 ppm, 2 ppm, 50 ppm, 100 ppm, respectively) in addition to control. PPFM and PGRs were sprayed at 30 and 45 days after the sowing of blackgram. Result: The experiment results of the two seasons study revealed that the application of 100% RDF + PPFM @ 2% recorded higher growth characters viz., plant height (cm), number of branches plant-1, leaf area index and yield attributes viz., number of pods plant-1, number of seeds pod-1, pod weight (g), pod height (cm), 100 seed weight (g) and yield viz., grain yield (kg/ha), straw yield (kg/ha) and harvest index (%). As well as the same treatment recorded higher net return and B:C ratio. Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield with a magnitude of 1.91 and 1.67, respectively. Therefore, application of 100% RDF+2% PPFM spray can be recommended as the best technology to improve the yield and economics of blackgram.
