The use of crop rotation in hydromorphic soils has been intensified in the state of Rio Grande do Sul, Brazil. Due to the difficult management of these soils, the use of irrigation is fundamental to increase the reliability of these production ecosystems. The present study aimed to evaluate the growth and yield components of corn under different managements of furrow irrigation. The study was conducted in Alegrete/RS in the experimental area of the Farroupilha Federal Institute during the 2017/2018 season. Two factors were evaluated: five managements of furrow irrigation, with a control (not irrigated) and 0, 25, 50 and 100% of the time required to replace the irrigation depth up to field capacity, and the influence of plant position relative to the total length of the furrow, at 0, 25 and 50 meters from its beginning. During the growth stage of corn, its LAI showed better performance for the three collections, at 34, 54 and 76 DAS, and plant height and shoot dry matter showed differences at 76 DAS in treatments that received irrigation. Yield components such as number of grains per ear, harvest index and grain yield were influenced by the use of irrigation, whereas water use efficiency did not differ between the use of irrigation and the control treatment. Lastly, best performances of application efficiency were found in treatments with 0% and 25% of the time required to replace the irrigation depth.

Between 1995 and 2008 the granting of the Binding Forest Award led to fresh cooperation between forest owners and research on silviculture, growth and yield at the Swiss Federal Institute for Forest, Snow and Landscape Research. Various topics were treated: a study of the beech coppices in Rothenfluh rapidly made it clear that very little was known about this formerly widespread type of forest management and its consequences. The same was true to a lesser extent for the conversion of rather uniform high forest into selection forest (in Plasselb), and for the selective management of light demanding tree species, such as the oak, in Rheinau. In Boudry, cooperation between practice and research already existed: the prize award here led to new approaches in the production of high quality oak, whilst taking ecological values into account. All these new projects are still in their earliest stages and will call for a great deal of “sustainability”, in both senses of the word, from all those involved. Considering the long periods of time required for the development of forest ecosystems, this is in fact self-evident.

The experiment was conducted at the Agronomy Field laboratory, Department of Agronomy and Agricultural Extension, University of Rajshahi to study the yield and yield components of wheat as affected by phosphorus fertilization. The experiment consisted of two factors i.e. (i) three wheat varieties viz., Shatabdi, Bijoy and Prodip and (ii) five levels of phosphorus viz. 0, 30, 60, 90, 120 kg P2O5 ha-1. A RCBD design was used for the experiment with three replications. The effect of variety was significant on all the yield components and yield except plant height. Prodip gave the highest grain yield (3.67 t ha-1) followed by Bijoy (3.45 t ha-1) and Shatabdi (3.28 t ha-1). Yield and yield components of wheat were significantly influenced by different levels of phosphorus. The highest grain yield (4.47 t ha-1) was recorded from P4 (120 kg P2O5 ha-1) and the lowest one (2.43 t ha-1) from the control treatment. The highest grain yield (4.80 t ha-1) was obtained from Prodip at 120 kg P2O5 ha-1 and the lowest one (2.3 t ha-1) was found in Shatabdi at control treatment. The results suggest that the combination of V3P4 (Prodip with 120 kg P2O5 ha-1) is the best for obtaining higher yield of wheat.

Although,chickpea isnitrogen fixing crop but water scarcity under rain-fed condition reduces its nodulation process severely and nutrients use efficiency too. An experiment was carried out regarding the combined effect of nipping as well as foliar applied fertilizers on yield and yield components of chickpea under rain-fed conditions. Nipping and foliar application of nutrients significantly improved number of pods plant-1, biological yield (kg ha-1), harvest index (%) and final grain yield (kg ha-1). However, non-significant influence was seen in 1000-grain weight and number of grains pod-1. Foliar application of N PK (20:20:20) @2.5 kg ha-1 × nipping was found to be the best interaction among others which significantly increased number of branches plant-1 (11.30), number of pods plant-1(115.36), plant height(59.48cm) and grain yield(2338.9 kg ha-1) as compared to the control treatment. Nipping along with foliar application of NPKcan be practiced in chickpea for higher profitability.

The experiment consists of two factors. Factor-A Vermicompost V0 (control), V1 (6 t ha-1 vermicompost), V2 (10 t ha-1 vermicompost) and V3 (14 t ha-1 vermicompost) and Factor-B Earthing up E0 (control), E1 (Two times earthing up) and E2 (Three times earthing up). The experiment was laid out in RCBD (Randomized Complete Block Design) with three replications. The collected data were statistically analyzed. Results revealed that in terms of vermicompost application The highest fresh weight bulb-1 (40.07 g), yield plot-1 (527.89 g) and yield ha-1 (5.39 t) were found from the treatment V3 compared to V0 (control) treatment. Again, in terms of different earthing up treatments, the highest fresh weight bulb-1 (32.48 g), yield plot-1 (431.67 g) and yield ha-1 (4.41 t) were found from the treatment E2 (Three times earthing up) compared to E0 (control) treatment. Both vermicompost and earthing up and their combination showed a considerable variation on different growth and yield parameters of onion. The highest fresh weight bulb-1 (42.73 g), yield plot-1 (567.33 g) and yield ha-1 (5.79 t) were found from the treatment combination of V3E2 compared to control V0E0 (control) treatment combination. And it may be summarized that 14 t/ha vermicompost with three times earthing up performed the maximum yield compared to other treatments.
